Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an invention in which fats and oils contained in juice and washing water of ramen are prevented from flowing into sewage and the collected fats and oils are effectively used as a recycling resource. Things.

[0002]

2. Description of the Related Art A grease strap is provided in a drainage route of a store that uses a large amount of animal and vegetable oils for cooking, for example, a Chinese restaurant or a ramen restaurant, so that oils and fats that are mixed with the residual rice do not flow into the sewer. This will be described with reference to FIG. 13. Reference numeral 30 denotes a washing tank (sink) installed in the kitchen. Reference numeral 31 denotes a grease strap. The grease strap 31 is connected to the washing tank 30 by a pipe 32.
The grease strap 31 has another lid 33 buried in the soil outside the kitchen (outside the building), and 34 allows the water in the grease strap 31 to flow to a sewer or a septic tank (not shown). It is a pipe for the purpose. This pipe 34 is connected to the bottom of the grease strap 31, as is apparent from the figure. The pipe 32 is connected to the upper part of the grease strap 31. Washing tank (sink) 3 of Chinese restaurant or ramen shop having such grease strap 31
As shown in the figure, the oil remaining at 0
Soup or dishwashing detergent. Since all wastewater such as oils and fats pass through the grease trap, they are separated into oils and fats and water in the grease strap 31, and only water is drained to the sewer. If the grease strap 31 is used, or if a large amount of detergent is used, the following problem is likely to occur in the case of the existing grease strap 31 only. For example, oils and fats adhere to the inner walls of the pipes 32 and 34, and are likely to be clogged by oils at last, and the oils and fats are not separated well by a grease strap. And pollute rivers. Alternatively, unless the grease trapped in the upper part of the grease strap is opened and removed periodically with human power, the odor goes out and deteriorates the surrounding environment. Further, there is another problem that even if an attempt is made to periodically remove the oils and fats, a large amount of water is taken, and it is difficult to treat the collected oils and fats. Among these problems, there is a proposal to automate the work of periodically opening the lid of the grease collected on the upper part of the grease strap and manually removing the grease with human power. Hereinafter, this proposal will be described with reference to FIG. 14. 35 is a washing tank (sink) installed in a kitchen.
The liquid waste and soup-containing water described in FIG. 36 is a grease strap (interceptor). The grease strap 36 has a separation tank 37. The grease strap 36 is buried in the soil outside the kitchen as shown in the figure. Thus, the fats and oils that flow into the washing tank 35 together with the water (for washing) enter the separation tank 37 from the inlet 39 of the grease strap 36 via the conduit 38. The oil or fat containing water is first separated by a filter 40 into a solid and a liquid. Then, in the separation tank 37, it is separated into water and oils and fats, and the oils and fats accumulate above the separation tank 37, and the water accumulates below it. The water accumulated below is drained from the drain 41 to the sewer. At this time, the proposed grease trap 36 uses the pump 42 to pump oil and fat floating above the separation tank 37 instead of human power. The oil and fat pumped up by the pump 42 is collected in an oil and fat collection unit 43. As an example of the grease removal system or the apparatus provided with the grease straps 31 and 36 shown in FIGS.
No. 6, JP-A-7-284767 and the like. still,
When installing the kitchen stand shown in FIG. 14 in a kitchen or the like, the consistency of the members naturally becomes a problem. Therefore, the existing washing table (kitchen table with washing tank, dust sink, work table with sink, Chinese cooker with sink, etc.) is unified, for example, with a height of 800 to 850 mm and a depth of 450 to 750 mm. When the width is used as a variable, many models are created. For this reason, for example, even if an expensive oil and grease removing device can be technically incorporated in the above-mentioned washing stand, it has been impossible for the manufacturer to cope with the cost. From this point, in the past, a simple kitchen stand or the like was mainly used and marketed. Japanese Patent Application Laid-Open No. 2000-84542, filed and published by the same applicant, discloses an oil / fat removing apparatus for removing an oil / fat contained in ramen or the like. In other words, this is a store that uses a lot of animal and vegetable oils for cooking,
For example, to remove grease from the Chinese restaurant or ramen restaurant that flows into the washing tank of the kitchen mixed with the garbage left before entering the grease strap (interceptor) to prevent the grease strap (interceptor) from becoming dirty. , At least between the washing tank (sink) and the grease trap (interceptor) in the kitchen, at least a washing tank dedicated to fats and oils and a fat-separating tank whose temperature is controlled,
An oil / fat removing device having means for removing the oil / fat accumulated above the oil / fat separating tank is interposed. However, in the oil and fat removing device, the temperature of the separation tank is controlled by being heated by a throw-in type heater. Putting a throw-in type heater directly into the separation tank means that the previous heater is placed in water containing a large amount of salt, etc., so that the heater is naturally made of a material with excellent corrosion resistance. And must be. For this reason, cost increases are unavoidable. Further, there is another problem that when the entire separation tank is heated by the heater, the surface area of the heater must be increased to provide a structure capable of heating the entire tank.

[0003]

As described above, conventional kitchen stands are not equipped with a grease removing device, and therefore, when they are washed in the sink (wash tank) of the above-mentioned washing stand, The problem of the grease trap described on the left was retained as it was. Also, according to the kitchen stand maker side, even though the dimensions are unified to some extent, it means that all high-priced grease removal devices are incorporated in each type of kitchen stand with different height and width dimensions, for example It was very difficult, if technically possible, to finance. On the other hand, it has been impossible for a user to purchase a washing table provided with a grease removing device or the like suitable for each kitchen. Further, there has been no device for collecting oils and fats contained in washing water and applying the collected oils to recycled resources. Furthermore, there is no electric heater that heats the inside of the separation tank considering the installation conditions from the aspect of corrosion resistance.
Further, the present invention relates to an invention for increasing the surface area of an electric heater.

[0004]

The present invention has been made to solve the above-mentioned problems. That is, it is composed of an oil skimmer for pumping oil and fat stored on the upper surface of the separation tank, an oil tank and the like for storing oil and fat captured by the oil skimmer,
A release plate is provided between the oil tank and the oil skimmer, and the oil and fat separated from the oil skimmer is guided to the oil tank via the release plate, and water containing oil and fat in the separation tank is removed. A heating heater for heating is provided independently of the separation tank, and the heating chamber is filled with water and the like, and the water containing oil and fat in the separation tank is heated through the heated water and the like. Therefore, it is possible to solve the above-mentioned problem and to efficiently recover the fats and oils. In other words, even if a dish, a dish, or the like contaminated with oils and fats is washed and flushed as it is, in the case of the present invention, the oils and fats directly flow into the sewage due to the interposition of the oil and fat removal device between the sewage. Of course,
The collected fats and oils can be effectively used as recycled resources with low environmental impact. Specifically, since the heating chamber provided independently of the separation tank is provided in the separation tank and the heating chamber is provided over almost the entire height of the separation tank, the entire separation tank is overheated from top to bottom. Things. At this time, the heat of the heater is efficiently transferred into the separation tank through the water in the heating chamber. Furthermore, since the temperature of the water containing oils and fats in the separation tank is such that the upper part of the tank is heated and the lower part thereof is heated by the heater, the oils and fats are about 80 to 60 degrees, and The relatively odorous water containing fine-grained slag at the bottom of the tank has a temperature of 50 to 30 degrees at which no odor is generated, and the fats and oils are efficiently pumped to the oil skimmer side. In addition, the water located in the lower part of the separation tank contains fine-grained slag, so when it is solidified, it emits an unpleasant odor.However, since the lower part of the tank is also appropriately heated, the solidification is prevented and the generation of unpleasant odor is prevented. is there.

FIG. 12 is a further development of the auxiliary separator shown in FIG. 10, and FIG. [I] is a washing table provided with the present invention (this washing table [I] includes a kitchen table, a work table, a Chinese cooker table, etc.). In addition, a washing tank 1 dedicated to fats and oils for washing dishes, dishes and the like contaminated with fats and oils is provided on the front side. The oil / fat cleaning tank 1 constitutes a cleaning tank 1 dedicated to oil / fat of an oil / fat removing device 2 described later.
Is an oil tank for storing the oil and fat collected by the oil and fat removal device 2. [II] is a top plate forming the upper surface of the washing table [I], and the outer shape of the top plate [II] is used for various kitchen tables provided adjacent to the main washing table [I] in a kitchen or the like. Made together. That is, by replacing the top plate, it can be adjusted to any adjacent kitchen table. For this reason, the top plate is mounted so as to be detachably mounted on the lower oil / fat removing device 2, and the outer dimensions do not always match those of the oil / fat removing device 2. In other words, this top plate [II] has a height and a depth of an adjacent kitchen table (for example, height 80).
0-850, depth 450-750 mm). Furthermore, if the manufacturer prepares only this kind of top plate, it can always supply a consistent kitchen table in a normal-sized kitchen. This will be described in more detail with reference to FIG. 2.

Has a flange portion [IIb] that enters into the inside of the upper surface opening portion. Reference numeral 2a denotes a support provided on the grease removing device 2. The top plate [II] is mounted on the support 2a with the outer frame [IIa] mounted thereon.
On the other hand, the flange portion [IIb] of the top plate [II] is mounted so as to just enter the inside of the upper surface opening of the grease removing device 2. Reference numeral 12 denotes an oil tank, 15 denotes a duct to be described later, 9 denotes a drain port, 1 denotes a cleaning tank exclusively for fats and oils, and the drain port 1a is assembled so as to correspond to the drain port 9 of the duct 15. Next, the grease removing stem (entire configuration) will be described with reference to FIG.
1 is a washing tank (sink) dedicated to fats and oils installed in the kitchen,
In this washing tank (sink) 1, liquid residue rice such as ramen soup, ordinary soup, sauce, and dressing is poured.
Of course, the washing tank (sink) 1 dedicated to fats and oils is also provided with a snowboard (filter) not shown in the figure for preventing solids from flowing downstream. Reference numeral 2 denotes an oil / fat removing device, and the oil / fat removing device 2 includes a cleaning tank (sink)
Liquid waste that has flowed through the pipes (duct 15 described later)
In addition to the above-mentioned liquid waste, wastewater containing grease from tableware and cooking utensils flows into the grease removing device 2 via the duct 15 through the washing tank dedicated to grease. Reference numeral 5 denotes a washing tank (sink) in the kitchen. In this washing tank 5, drainage that does not contain oils and fats, such as tableware, soaking water for cooking utensils, drainage for dishwashers, and washing water for vegetables, is supplied. The grease strap 7 is sent to the grease strap (interceptor) 7 via the grease strap 7 and is generally employed. The grease strap 7 is used to flow non-oil and grease into the sewer 8 and store the grease in the grease strap 7. It is. The drainage from which most of the oil and fat has been removed by the oil and fat removal device 2 described above is introduced through the pipe 3 in the middle of the pipe 3, in other words, after the washing tank 5 and before the grease trap 7.
In addition, the grease removing device 2 and the cleaning tank 1 dedicated to the grease are integrally formed, and are usually provided together with the cleaning tank 5 in the kitchen in a normal state. In this way, the people working in the Chinese restaurant usually select the liquid residue containing oil and fat in the washing tank 1 dedicated to oil and fat and the wastewater without oil and fat in the washing tank 5 as normal work. It can be drained. As mentioned above,
The liquid residue containing fats and oils passes through the fats and oils removal device 2,
Drained to the sewer via existing grease straps. As a result, the sewage system is not contaminated as in the prior art, and the frequency of cleaning the grease strap itself can be greatly reduced.

Next, the overall structure of the grease removing device 2 incorporated in the washing stand [I] will be described with reference to FIG. 4. The washing stand [I] having the grease removing device 2 is installed in a kitchen. However, there is no problem even outside the kitchen (outside the building). The height of the grease removing device 2 is 800 to 850 mm with the top plate [II] described above attached.
It is made in. Reference numeral 1 denotes a cleaning tank dedicated to fats and oils, and the cleaning tank 1 dedicated to fats and oils is used for cleaning dirt from liquid residue and dishes and cooking utensils. Reference numeral 10 denotes an oil skimmer that causes oil and fat to adhere (adsorb by hydrophobic interaction) to a metal belt described later and pump the oil and fat from the separation tank 11. Numeral 12 denotes an oil tank where the oil and fat pumped up by the oil skimmer 10 is temporarily stored. Since the fats and oils stored in the oil tank 12 are pure fats and oils containing no water, they can sufficiently withstand recycling. Reference numeral 11 denotes a separation tank, which will be described in detail with reference to FIGS. As described above, the washing tank 1 dedicated to fats and oils
In addition to the liquid residue and the like, tableware 13 contaminated with oils and fats is supplied and washed there. As shown in FIG. 9, the introduced liquid waste or the water containing the washed fats and oils is supplied from a drain port 9 to a duct 15 provided on an outer wall surface 14 a of a second separation tank 14 formed by partitioning the separation tank 11. Discharge port 1 via
The second separation tank 14 is taken into the second separation tank 14 from FIG. 6, and this second separation tank 14 is independent of the separation tank 11 as shown in FIG. Things. Along with this, the cleaning tank 1 dedicated to fats and oils is of course also of a detachable built-in type. Reference numeral 21b denotes a heating chamber provided on the side wall of the separation tank 14, and the heating chamber 21b is usually made of the same material as the stainless steel that forms the separation tank 14. The heating chamber 21b is provided over almost the entire height of the separation tank 14, as shown in FIG. Further, the heating chamber 21b will be described later. A heating heater is provided to heat the inside of the separation tank 14 via water filled in the heating chamber 21b.

Returning to FIG. 3, the water containing the fat and oil entering the second separation tank 14 from the discharge port 16 is guided by the guide plate 22 to guide the fat and oil of the liquid residue upward and the water downward. I will Reference numeral 10 denotes an oil skimmer, which is one of means for removing oils and fats by an adsorption action.
Is driven by a drive motor 17. For example, the thin stainless steel belt 18 is rotated as shown in the figure, and the fats and oils are pumped to the upper portion by utilizing an adsorption action such as hydrophobic interaction with the belt. Accordingly, the lower end of the belt 18 is immersed above the second separation tank 14 in which the oils and fats accumulate. The oils and fats pumped by the belts 18 are separated from the belts 18 by the peeling plate 19 and pass through the auxiliary tank 20. , To the oil tank 12. The release plate 19a
Is provided so that the oils and fats attached to the belt 18 are separated before reaching the drive motor 17. or,
The role of the auxiliary tank 20 is to flow only oil and fat into the oil tank 12 and to return impurities including water and the like to the separation tank 14. That is, as shown in the figure, the auxiliary tank 20 incorporates a double-pipe separation device 20a, and impurities such as water accumulated in the lower portion are returned to the separation tank 14 as shown by arrows. In addition, an adsorption mat (not shown) can be used in place of the oil skimmer as a means for removing the oil and fat by the adsorption action. 21 is the inside of the second separation tank 1
4 is heated by a heater for preventing solidification (increase in viscosity) of fats and oils in the second separation tank 14.
It is installed in. The heater 21 installed in the heating chamber 21b heats the inside of the separation tank 14 via water filled in the heating chamber. It is well known that, unlike mineral oils, animal and vegetable oils increase in viscosity at low temperatures. One of the features of the oil and fat removing apparatus of the present invention is that a heating means is provided to absorb or pump oil or fat from a separation tank using an oil absorbing mat (not shown) or an oil skimmer 10 even when the ambient temperature fluctuates. It is one that can be fried. In addition, in order to perform efficient adsorption etc., it is good to maintain the temperature of the place where the fats and oils are stored in the upper part in the separation tank at 60 to 80 degrees. From the viewpoint of temperature control, it is advantageous to separate the second separation tank 14 from the separation tank 11 and reduce the volume in consideration of power saving and the like.
Further, the heater 21 naturally has a temperature control section 21a, and always controls the temperature of the second separation tank 14 in an optimum state. That is, the temperature in the upper portion of the separation tank 14 is set to a temperature at which oil and fat easily adhere to the belt 18 (60 to 80 degrees), and the temperature in the lower portion of the separation tank 14 is set at Temperature at which odor does not appear from [fine particles] (4
0 to 60 degrees). Heating heater 21
Is supplied to the separation tank 1 via the water filled in the heating chamber 21b.
4 is conducted. That is, the water acts as a conductor to heat the inside of the separation tank 14. The reason why the heater 21 is installed in the heating chamber 21b is to efficiently heat the inside of the separation tank 14 using the water in the heating chamber 21b. Therefore, even if the animal or vegetable oil reaches the solidification temperature at ambient temperature, the oil does not solidify in the tank. This is also true when the present fat and oil removing device 2 is placed outside a building. Further, if the bottom of the auxiliary tank 20 is located in the water in the separation tank 14 so that the heat of the heater is applied to the auxiliary tank 20, the oils and fats do not solidify in the auxiliary tank 20 and are always good. High liquidity.

Reference numeral 23 denotes a double-tube auxiliary separation tank provided on the separation tank 11 side. This auxiliary separator 23 is shown in FIGS.
As shown in FIG. 1, the outer pipe 23 protrudes from the bottom of the separation tank 11.
a protrudes above the oil and fat surface 24a, and the inner tube 23b is set to be equal to the water surface 24b. And, as shown in FIG. 11, a water intake port 25 is provided below the water surface 24b in the outer tube 23a. Water is taken in from the upper end of the inner tube 23b. In the drawing, reference numeral 26 denotes an oil-absorbing mat, and this oil-absorbing mat 26 is to finally dispose of oils and fats that are not captured in the separation tank 14 and reach the auxiliary separator 23 side. When the oil supply mat 26 is not used, if the oils and fats in this portion are periodically removed manually, the device can be efficiently used for a long period of time. Here, a development of the auxiliary separator 23 will be described with reference to FIGS. 23 is an auxiliary separator, this auxiliary separator 23
Are connected to the drain side pipe 27, and traps A, B, and C for separating water and fats and oils with a specific gravity difference inside.
As shown in FIG. The auxiliary separator 23 is composed of a main pipe 23C composed of a triple pipe and a branch pipe 23d composed of a double pipe.
The lower end of 3d is connected with a horizontal pipe 23e. 23
f is a branch pipe 23f provided in the middle of the horizontal pipe 23e. Separation of water and oil in the auxiliary separator 23 will be described below. The water from which most oils and fats have been removed by an oil skimmer or the like is configured to be guided to the lower part of the separation tank 11 as shown by an arrow in FIG. This water proceeds as shown by the arrow and is guided upward by the inclined portion 23g of the branch pipe 23d formed of a double pipe. At this time, the function of the inclined portion 23g rises as shown by the arrow, giving a lifting force to the water containing oil and fat, thereby increasing the water intake port 2.
It works to make it difficult for oils and fats to enter from 5a. The water that has reached the water intake 25a is divided as indicated by an arrow and an arrow circle 10. The portion that separates water and oil before and after the water inlet 25a is a trap A. That is, water and fats and oils are separated by utilizing the specific gravity difference between the fats and oils and water. Water intake 25
The water containing the oils and fats that has entered the branch pipe 23d from the point a. proceeds as indicated by the arrow almost directly to the water intake 25b of the inner pipe that is not provided so as to face the water intake 25a. The oil intake rises to the water surface side.
The place where water and oil are separated before and after 5b is trap B. As for the water containing fats and oils, which has entered the inner pipe of the branch pipe 23d composed of this double pipe, only the fats and oils float up as indicated by an arrow circle 11, and the water containing a slight amount of fats and oils becomes an arrow 12
As shown in the figure, it descends due to the drainage power of the drain.
3e reaches the branch pipe 23f. Also in this part, the oil and fat floats up to the water surface side as shown by the arrow, and the water containing the oil and fat that has passed through this goes to the main pipe 23c side and reaches the main pipe 23c. Even at this time, the horizontal pipe 23e is connected to the water intake 25
Since it is located below b, the mixing of oil and fat is drastically reduced. The fat and oil reaching the trap C is indicated by an arrow 13.
The water is separated as indicated by arrow 14. What is particularly important is that the water inlet 25c provided in the middle pipe of the main pipe 23c formed of a triple pipe is provided below the trap C at a distance. By taking this distance sufficiently, the fats and oils contained in the flow of water indicated by arrow 14 cannot rise and rise to the water surface side as indicated by arrow 13. In other words, the water inlet 25c is provided near the bottom of the separation tank 11. On the other hand, the water that has entered the middle pipe through the water inlet 25c as shown by the arrow 15 rises and is guided to the drain pipe 27 through the opening 25d of the inner pipe. Also at this time, the fat and oil components float on the horizontal plane as indicated by the arrow 16 due to the trap D, and only the water flows as indicated by the arrow 17.
It is to the drain side. In this way, the auxiliary separator 23 allows the water flowing in the auxiliary separator 23 to pass through the trap portions provided at a plurality of locations based on the suction force of the water flowing through the drain to remove fats and oils, and to cleanly purify the purified water downstream. They try to flow to the side. The auxiliary separator 23 is provided with lids 23h and 23i at the tops of the main pipe and the branch pipe, respectively, so that the external appearance is organized well. It can be removed from time to time with an oil absorbing mat or the like. Returning to FIG. 3, reference numeral 27 denotes water separated by the auxiliary separator 23 in FIG.
This is a pipe that leads to the grease strap (interceptor) described in (1). As described above, the drainage of the present oil / fat removal device 2 is not directly drained to the sewer but is drained to the existing grease trap 7 (see FIG. 5). 28 is the separation tank 1
1, the cleaning drain cap 28 is provided at the bottom of the separation tank 11 for cleaning the inside of the tank.
After draining all the water out of the tank, the washing tank 9 dedicated to fats and oils, the oil skimmer 10, the oil tank 12, the second separation tank 14, the heating heater 21 and the like incorporated in the separation tank 11 are sequentially removed and washed. Is what you do. FIG.
As shown in FIG. 3, a heat conductive plate 19b is attached to the peeling plate 19, and the heat conductive plate 19b is in close contact with one end so as to cover the entire back side of the peeling plate 19, as is clear from FIGS. The other end is immersed in the auxiliary tank 20 heated in the separation tank 14. In other words,
The release plate 19 is heated by receiving the heat of the separation tank 14 heated to about 60 degrees to 80 degrees to prevent the oils and fats flowing on the release plate 19 from solidifying on the release plate 19. Is what it is. It is to be noted that the fat or oil is easily solidified not only when the outside air temperature is falling as in winter but also immediately before the end of the operation of the present fat and oil separating and removing apparatus. That is, it is a time when the amount of flowing fats and oils decreases and adheres to the peeling plate 19 due to surface tension. In order to prevent this, the peeling plate 19 is heated by the heat conducting plate 19b. The heat conducting plate 19 is made of copper or aluminum having good heat conductivity, and the whole of the peeling plate 19 is made of a material having poor heat conductivity such as stainless steel. It is necessary to warm. FIG. 7 shows an embodiment different from FIG. 6, in which the entire back surface of the peeling plate 19 is heated by a heater. In this case, the temperature of the peeling plate 19 can be controlled to 30 to 50 degrees by controlling the input of the electric heater 19c without using any special means. FIG. 8 shows the heat conductive plate 1 shown in FIG.
An example is shown in which an electric heater 19c is used to assist when the heat carried by 9b is insufficient and the release plate 19 cannot be heated to 30 to 50 degrees. Further, although not shown in the drawings, the present invention has been described in detail with an example in which the peeling plate 19 is heated. However, since the present invention can be applied to the auxiliary tank 20 located on the downstream side of the peeling plate 19, If necessary, this is also heated by various means. By doing so, the oil and fat separated from the oil skimmer passes through the peeling plate 19 and the auxiliary tank 20 so that the oil tank 1
2 is guided by a liquid, solidified and deposited on the way, and does not prevent the next flow. The supply of the washing water containing oils and fats to the washing table with the top plate is not shown in the drawing,
If a height difference or a pump is used, a cleaning tank dedicated to fats and oils and a fat and oil removing device can be placed at separate positions. Next, the oil removing step in the oil removing device 2 having such a configuration will be described with reference to FIG. The liquid is introduced into the second separation tank 14 from a discharge port 16 as shown by an arrow via a duct 15 provided in the tank 14. The wastewater containing fats and oils that has entered the second separation tank 14 is separated into water and fats and oils by the guide plate 22. The fats and oils float on the surface while maintaining an appropriate viscosity without solidifying because the second separation tank 14 is heated by the heater 21 provided in the independent chamber. The oil floating on the surface is pumped up by the oil skimmer 10 or the like. The pumped-up fats and oils are stored in the oil tank 12 via the peeling plate 19 and the auxiliary tank 20, and are recycled. On the other hand, the water from which the fats and oils have been removed
From the wastewater that reaches the separation tank 11 through the bottom of the guide plate 22 to the arrow part and further from the second separation tank 14 to the separation tank 11 as indicated by the arrow, the oil and fat component (oil skimmer 1)
The fats and oils that could not be removed at 0 float upward due to the difference in specific gravity and are adsorbed on the oil absorbing mat 26. The oil-free water enters the auxiliary separator 23 composed of a double pipe as shown by an arrow, enters the pipe 27 from the upper end of the inner pipe 23b, and is guided to the grease strap 7 (see FIG. 3). By installing the grease removal device 2 in front of the grease strap 7 in this manner, contamination of the grease strap 7 can be suppressed. Further, as shown in the present fat and oil removing device 2, a caster 29 is provided. The washing table with a top plate of the present invention can be easily moved not only in the kitchen but also outside the building. In other words, the kitchen table with the top plate can be moved to an easy-to-use place in a shop or the like and used. Further, since the peeling plate 19 is heated, the oil or fat peeled off from the oil skimmer 10 solidifies in the process of flowing through the peeling plate 19 and does not adhere to the peeling plate 19. If the oil or fat once solidifies and accumulates on the peeling plate 19, the next oil or fat flows on the surface of the solidified oil or fat, so that the accumulation is accelerated more and more. This indicates that the release plate 19
Means that it is necessary to always heat the substrate to 30 to 50 degrees regardless of the ambient temperature. The present invention has realized this. Another feature of the present invention is that the second separation tank, the oil skimmer, the oil tank, the auxiliary tank, the heating heater, the auxiliary separator, etc., are all easily detachable based on the separation tank 11, It is superior in serviceability.

[0009]

As described above, the present invention comprises an oil skimmer for pumping oil and fat stored on the upper surface of the separation tank, an oil tank for storing oil and fat captured by the oil skimmer, and the like. A separation heater is provided between the separation tank and the oil containing the oil and fat in the separation tank. It is provided independently of the tank, and the heating chamber is filled with water and the like, and the water containing oil and fat in the separation tank is heated through the heated water and the like. It can be prevented and can provide tremendous effects such as collecting and recycling oils and fats.Also, the separation tank can be heated to an appropriate temperature, so that oils and fats can be collected efficiently and the generation of unpleasant odors from the separation tanks is suppressed. Bets are those that can be. In particular, the function of the grease strap, which could not withstand long-term use, can be prevented, and oil and fat can be collected regardless of the ambient temperature.
The double or triple oil / fat removal function has the effect of further improving the purification of wastewater flowing to the sewer. Further, the life of the heater is further improved because the heater is introduced into the heating chamber (a chamber filled with clean water) without being directly introduced into the separation tank.
