Description

The reproduction apparatus of feed or compost using food waste}

The present invention relates to a feed and compost recycling apparatus for food waste, and in particular, to sterilize, dry and process food waste so that it can be easily removed and treated with water to remove salts so that it can be safely used as livestock feed or compost. It relates to a feed and compost recycling apparatus of food waste.

In general, a method of treating food waste or animal waste is incineration, landfilling or purification to discharge into a stream, or fermentation with a fermentation apparatus and recycling to compost or livestock feed.

However, the method of incineration has an inefficient disadvantage because the food waste contains too much water and consumes too much fuel.

In addition, the landfill or discharge into the river is a wastewater that causes water pollution by eutrophication of the river as it flows into the river due to the groundwater contamination by the leachate and the lack of purification facilities or lack of treatment capacity.

Compared to this, the fermentation method is more effective because it can be used as feed for livestock such as compost or chicken.

However, since food contains a lot of salt, it is difficult to regenerate livestock feed and compost unless the salt is removed.

Therefore, it is a problem to be solved to effectively treat salt in such food waste.

In addition, the food waste includes various metals, glass, toothpicks, and the like, and if the livestock is eaten, there is a risk of serious damage.

Accordingly, an object of the present invention is to provide an apparatus for effectively treating salt as well as a process for treating food waste economically and effectively by devising to solve the problems described above.

In addition, the purpose of the present invention is to provide a feed for the livestock to eat safely by performing effective sterilization treatment by selecting and removing various metals, glass and toothpicks, etc. contained in the food waste.

1 is a food waste treatment process flow chart according to the present invention, Figure 2 is a food waste treatment process diagram according to the present invention.

The food waste is collected in a separate food waste collection vehicle and dropped off in the storage hopper 10 to be temporarily stored.

Since the collected food waste is a mixture of vegetables and fish bone grains, the food waste shredding process is performed because the particle size and physical properties are different.

The primary shredding operation is performed through the shredder 20 to make the particles of the food waste fed through the feed shoe 11 of the storage hopper 10 into particles suitable for processing into feed and compost.

The shredder 20 to shred the food waste to a suitable size in this way to install the shredding blade 25 in the center of the cylindrical body 21 formed with the inlet 22 and the outlet 23 up and down to beat the falling food waste It is structured to be crushed. That is, a plurality of shredding blades 25 are radially installed around the rotary shaft 24, and the shredding blades 25 are hinged to the rotary shaft 24 to be rotatably coupled to each other so that the rotary shaft 24 rotates. It is spread out in a radial manner to break up food waste. At this time, when the unfragmented contaminants such as metal, synthetic resin, wood, etc. fall, the shredding blade 25 is rotated to prevent breakage of the shredding blade 25.

Food waste that has passed through the shredding process contains various wastes that cannot be used as feed or compost, such as synthetic resins such as PE and PP, metals, wood, glass, etc. Things must be screened because they can be fatal to animals. Therefore, the sorting operation is carried out through a separate sorter (30).

Separator (30) for removing contaminants from food waste is a vibrating device (33) for vibrating the screen conveyor (31) to be transported to the top of the screen conveyor 31 is installed at the bottom of the shoe to supply food waste Is installed, the transport conveyor 34 for transporting the food waste passed through the screen at the lower portion of the upper screen conveyor 31 is configured separately. In addition, one side of the screen conveyor 31 is provided with a discharge device for discharging the impurities that did not pass.

By this configuration, the food waste fed by the quantitatively falls through the screen conveyor 31, and the synthetic resin such as various vinyls contained in the food waste, or other impurities such as metal, wood, etc., do not pass through the screen conveyor 31. Transported for disposal. The food waste passing through the screen conveyor 31 is transferred to the next process through the transfer conveyor 34 at the bottom.

Food wastes that have undergone crushing and sorting are required to have a suitable pH as feed or compost, and thus undergoes a process of adjusting the pH through the PH concentration control device 40.

PH concentration control device 40 is installed in a circular tank (41) having inlet and outlet (42a, 42b) on both sides as shown in Figure 3 so as to rotate horizontally, the inlet for introducing food waste into the inlet (42a) The pipe 44a is connected, and the discharge port 42b is connected with the discharge pipe 44b. The rotation of the circular tank 41 is to rotate by connecting the power of the motor M1 to the chain 46 by installing a sprocket 45 around the circular tank 41. Alternatively, a gear (not shown) may be installed around the inlet 42a or the outlet 42b and rotated by power. And the rails (49a) are formed around both sides of the circular tank (41) for smooth rotation, the guide roller (49b) to guide the smooth rail (49a) to guide the smooth rotation while supporting the load is installed have.

The inflow operation of food waste into the circular tank 41 may be introduced by installing a transfer screw 441 in the inlet pipe 44a, and pumped through a separate pump (not shown). You can also supply. In addition, the discharge pipe 44b is installed to be close to the bottom of the circular tank 41 by bending the end thereof, and to suck and discharge food waste through a pump. Inlet and outlet ports 44a and 44b are provided with air inlet and exhaust pipes 47a and 47b for supplying oxygen therein. End of the air inlet pipe (47a) is bent to the bottom and horizontally piped close to the bottom of the circular tank 41, a plurality of air blowing nozzles (471) is installed on the top to distribute the air evenly distributed The end portions of the exhaust pipes 47a and 47b are bent upward in the circular tank 41.

The inner wall surface of the circular tank 41 is provided with a plurality of guide vanes 43 having an inclination angle in the discharge direction, so that the food waste is gradually transported toward the outlet 44b when the circular tank 41 is rotated. In addition, an open / close door 48 is provided around one side of the circular tank 41 so that the circular tank 41 can be repaired or cleaned if necessary. In addition, the lower portion of the circular tank 41 is provided with an indirect heating device through direct heating or heat medium oil to maintain a suitable temperature for fermentation.

Therefore, when food waste is introduced into the circular tank 41 through the inlet pipe 44a, the circular tank 41 slowly rotates and moves the food waste toward the outlet 42b and at the same time, evenly stirs it. In addition, air is introduced through the air blowing nozzle 471 of the air inlet pipe 47a to supply sufficient oxygen to the inside of the food waste, and to create an appropriate temperature condition by the heat supplied from the drying apparatus 50 to be described later. The fermentation takes place actively because of the cycle. In addition, the gas generated in the fermentation load is discharged through the air exhaust pipe (47b). In this process of fermentation, the pH concentration is appropriately adjusted and the food waste of which the concentration is controlled is pumped through the discharge pipe 44b and transferred to the sterilization process.

In the sterilization process, food waste is passed through a sterilization device 72 equipped with an ultraviolet lamp 72 to remove harmful bacteria. The ultraviolet sterilizer 72 has a structure in which a conveyor is passed through a sterilization chamber and a plurality of ultraviolet lamps 72 are installed on the sterilization chamber. UV sterilization may not affect within a certain thickness of the food waste to pass through, so that the food is configured to pass through in a thin spread state, and the length to have a length enough to achieve a sterilization action.

Meanwhile, since the sterilizer 70 has various sterilizers in addition to the sterilizer using ultraviolet rays, the sterilizer 70 may be sterilized using various sterilizers such as an ozone sterilizer in addition to the ultraviolet sterilizer.

The sterilized food waste enters the drying apparatus and goes through a drying process together with a desalination process.

In addition, the drying apparatus 50 has a plurality of salt removal device 60 on the inner upper portion of the body of a constant size as shown in Figure 4, the lower portion of the cylindrical drying cylinder 55 mounted with a transfer screw 58 therein up and down There are a number of horizontally installed.

The desalination device 60 and the inlet port 56a and the outlet port 56b of the drying cylinder 55 are installed so as to be arranged in opposite directions to each other so that the food waste passes them in a relay manner. The lower part of the drying chamber 50 is provided with the combustion chamber 51 in which the burner 52 was provided, and the heating plate 53 which radiates heat and far-infrared radiation is provided in the upper part of the combustion chamber 51.

Desalination device 60 is to compress the food waste and discharge it instantaneously to remove moisture and salt.

As shown in FIG. 5, the pressure feeding screw 63 connected to the motor M2 is provided inside the cylindrical cylinder 61 having the inlet and outlet 62a and the outlet 62b. At the rear side, a valve plate 65 for opening and closing the discharge port 62b is provided. The valve plate 65 is installed to flow on the extended shaft 64, and a tension device 67 for continuously pushing the valve plate 65 toward the cylinder 61 is installed at the outside thereof so that the cylinder 61 is always provided. It is supposed to block. Moreover, the edge part of the cylinder 61 and the contact surface of the valve plate 65 which contact | connects it are tapered.

When the food waste is introduced by this structure, the pressure feeding screw 63 is pumped toward the valve plate 65, so that the inside of the cylinder 61 is in a high pressure state. When the pressure inside the cylinder 61 becomes higher than the tension device 67, the valve plate 65 is momentarily opened to discharge the food waste inside. By this operation, the high-pressure food waste is discharged instantaneously and placed in a low pressure state, which causes the volume to inflate and the vaporization point of the water to be lowered, thereby rapidly evaporating. At this time, the salinity is also released and removed.

Figure 6 is another embodiment of the desalination valve plate of the present invention, it may be provided with a plurality of valve plate as shown.

This is because the feed screw 63 feeds the food waste so that the pressure acts on the valve plate 65 not uniformly acting on the entire valve plate 65, but at the portion where the end of the feed screw 63 is positioned highest. Since the torsion phenomenon occurs when the valve plate 65 is opened and closed, there is a fear that a smooth opening and closing operation may not be achieved.

In order to prevent this, the valve plate 85 is configured to be divided into a plurality of circumference of the sealing plate.

In view of the structure, the discharge port 62b of the cylinder 61 is blocked by the sealing plate 83, and a plurality of small discharge ports 84 are formed around the sealing plate 83, and each discharge port 84 has a shaft. The small valve board 85 which opens and closes and retracts in the direction is provided, respectively. Of course, the tension device 86 is provided in the outer surface of each small valve board 85, and the contact surface of the discharge port 84 and the small valve board 85 is tapered.

When the press screw 63 rotates by this structure and compresses food waste, the pressure acts on each valve plate 85. When the pressure is below the allowable pressure, the state closed by the tension device 86 is maintained as it is, and when the end of the pressure feeding screw 63 is rotated and pressure is applied, the valve plate 85 corresponding to the end of the pressure feeding screw 63 is momentarily. It is opened and closed to partially discharge the food waste. This phenomenon, the valve plate 85 also opens and closes in sequence according to the end operation of the pressure screw (63).

In addition, the drying cylinders 55 are provided with a transfer screw 58 that is rotated by the motor M3 therein, and the salinity removing devices 60 located at the upper side and the drying cylinders 55 at the lower portion thereof have respective inlets ( The guide shoe 57 is installed so that the 56a) and the outlets 56b can relay food waste to each other in a relay manner.

The feed screw 58 is configured to transfer food by fixing and fixing a screw piece 583 formed by winding a flat iron spirally around the shaft 581 around the shaft 581. In addition, the food waste to be transported is evenly distributed on the inner wall surface of the drying cylinder 55, and provided with a long spreading member 584 to increase the drying effect so as to slightly project around the screw piece 583 and rotate at the same time. It is provided in both sides of the feed screw 58 so that it may incline in the direction to become.

When the food waste is introduced by this structure, the feed screw 58 rotates to feed the food, and at the same time, the food waste to which the spreading member 584 installed around the feed screw 58 is conveyed is transferred into the drying cylinder 55. It spreads thinly on the wall and the drying action is done quickly.

In addition, the water and gas is generated in the process of drying food waste, the exhaust pipe 59 is installed in the upper portion of the drying cylinder 55 adjacent to the inlet 56a in order to easily discharge it. Therefore, air is introduced through the outlet 56b of the drying cylinder 55 to discharge gas and water vapor into the exhaust pipe 59. At this time, the exhaust gas discharged is odor because it is to deodorize it using a deodorizing device (591).

In addition, since the waste heat discharged from the drying device 50 to the exhaust port 592 is heated through the heat exchanger 593, the air is heated and then supplied to the PH concentration control device 40 to maintain a suitable temperature for fermentation, thereby adjusting the pH concentration. It is possible to further activate fermentation for.

As such, the food waste passed through the desalination device 60 and the drying device is subjected to the second sorting process again. At this time, various kinds of synthetic resins or metals and glass that are not removed in the primary screening process are screened.

Food waste that has undergone the sorting process is shaped into pellets that are easy to eat for livestock, and cooled to a temperature that is easy to pack through a cooling process. The cooled food waste is packaged in a wrapping paper of a suitable capacity through a packaging process to be shipped.

As described above, the food waste feed and compost recycling apparatus according to the present invention has to go through the screening process twice in the process of transporting food waste to efficiently collect the substances that can not be used as livestock or the contaminants that can not be used as compost It can be filtered and sterilized, thereby increasing the stability of the feed.

In addition, by discharging the food waste instantaneously from high temperature high pressure to low temperature low pressure, there is an effect that the salt can be reliably removed by discharging the water and salt contained in the food waste together.
