Description

TECHNICAL FIELD [0001] The present invention relates to a polishing apparatus for polishing wastewater,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an abrasive wastewater treatment apparatus for an abrasive machine, and more particularly, to a polishing abrasive wastewater treatment apparatus for abrasive wastewater by collecting abrasive wastewater generated in a process of cutting a lens for a spectacle lens using an abrasive machine to produce sludge, The present invention relates to an abrasive wastewater treatment apparatus for an abrasive wastewater which is capable of preventing the discharge of abrasive wastewater causing environmental pollution by discharging it after drying.

Generally, in order to purchase glasses suitable for the eyesight, the consumer searches the optician, finds a lens of a frequency suitable for his or her vision, selects a spectacle frame having a desired design, and inserts the lens into the selected spectacle frame.

On the other hand, since lenses are generally manufactured in a factory and manufactured in a circular shape at the factory, the spectacle frame has a variety of designs. Therefore, in order to mount the lens on the spectacle frame, it is necessary to cut the edge of the lens to fit the shape of the spectacle frame An apparatus used for cutting such a lens is generally referred to as an'oxidizer '.

The lens used for the spectacles is usually made of glass or plastic material. If the lens is cut by using the jade moisture, heat is generated due to friction during the process, The polishing water is used for lubrication and cooling.

However, since fine abrasive grains are generated at the time of cutting the lens, these abrasive grains are mixed with polishing water and discharged as abrasive wastewater. Conventionally, such abrasive wastewater is immediately discharged through the sewer so that water consumption due to lens processing is large, Not only is it wasteful, but also has a disadvantage in that a cost burden due to the use of polishing water is increased.

Thus, the polishing wastewater generated during the cutting process of the lens is collected in the collection container 20 of about 20 to 40 L, and the collected wastewater is filtered using a filter to reuse the filtered wastewater as polishing water, And if it is difficult to further filter, it is discharged through a sewer.

However, in the case of such a conventional abrasive wastewater filtration and reuse method, by using a fiber filter to filter the abrasive wastewater, it is possible to effectively filter the abrasive particles in the course of filtering the abrasive wastewater. On the other hand, Clogging of the filter due to particles frequently occurs.

Therefore, the amount of the filter used increases, and therefore frequent replacement of the filter is inevitable, which leads to an increase in the cost and burden of the maintenance.

In addition, the amount of water consumption can be reduced through filtration and reuse of abrasive wastewater, but the abrasive wastewater reused for a certain period is eventually discharged through the sewer. In recent years, there has been a problem of environmental pollution due to unauthorized discharge of lens abrasive wastewater It is true.

That is, in recent years, the lens for spectacles is mainly manufactured by using a plastic material having a light weight instead of glass. In the case of a lens made of a plastic material, petrochemical products are mainstream. Therefore, abrasive wastewater containing abrasive particles In addition to various heavy metal components, there are substances that are toxic to water pollution such as dichloromethane, chloroform, phenol, cyan, 1,4-dioxane and formaldehyde, which are carcinogenic substances and carcinogenic suspicious substances.

Therefore, when the abrasive wastewater containing various heavy metal components is discharged through the sewer, there is a possibility of causing serious water pollution and environmental pollution. Thus, it is possible to effectively treat the polishing wastewater generated during the cutting process of the lens It is inevitable to develop an abrasive wastewater treatment apparatus for an abrasive machine which can reduce water consumption and prevent environmental pollution.

Will be described with reference to Figs. 2 to 4. Fig.

An abrasive wastewater treatment apparatus for an abrasive machine of the present invention comprises: a main body case (1); A water treatment section 2; A water circulation unit 3; A sludge transfer section (4); A sludge drying unit 5; And a control unit. The water treatment section 2 of the abrasive wastewater treatment apparatus for an abrasive includes a collection tube 20 and a sludge filtering net 21 for collecting abrasive wastewater and separately collecting the sludge produced by the collected abrasive wastewater.

The water collecting container 20 is formed with a water inlet 201 having a first filter 201a for primarily filtering the abrasive wastewater discharged from the oven, and collecting the collected abrasive wastewater into the oven And a drainage section 202 having a second filter 202a for secondary filtration to supply the water. The water collecting tube 20 is installed at one side of the body case 1 in order to collect the polishing water discharged from the oven and to store the water supplied through the water line 311.

It is preferable to limit the amount of the water or abrasive wastewater collected in the water storage tank 20 to 50 to 60 liters, but it is not limited thereto.

A flexible hose 201b is provided between the jaw and the water inlet 201. A stopper 201C removable from the water inlet 201 is installed at the end of the connecting hose connected to the water inlet 201 do.

Inside the cap 201C, a first filter 201a for filtering foreign substances having a diameter of 1 mm or more, such as lens fragments contained in the polishing wastewater flowing through the connecting hose, is detachably installed.

That is, an insertion groove 201d is formed in the stopper 201C so that the first filter 201a is inserted into the insertion groove 201d, and a male threaded portion is formed in a female threaded portion formed outside the insertion groove 201d The first filter 201a can be attached and detached by disassembling and assembling a fixed cap 201e.

Accordingly, the first filter 201a can easily and decompose the first filter 201a when a large amount of filtrate is filtered through the first filter 201a due to long-term use, by using a metal mesh type filter which can be used semi-permanently. It can be reused after washing.

The second filter 202a uses a metal mesh type filter for filtering foreign substances having a diameter of 1 mm or more, such as lens fragments contained in the polishing wastewater, like the first filter 201a, so that large particles mixed in the polishing wastewater The filtered water is discharged through the drainage part 202 and supplied to the oven, thereby enabling repeated reuse of the water.

The second filter 202a may have a detachable structure such as the first filter 201a. By using a metal mesh type filter that can be used semi-permanently, such as the first filter 201a, It is preferable to disassemble, clean and reuse the second filter 202a when a large amount of foreign matter is filtered in the filter 202a.

As time elapses, sludge is produced as shown in Fig. 3, and the sludge coagulates and expands over time and is suspended in the polishing wastewater.

That is, a large amount of abrasive grains are mixed in the abrasive wastewater generated in the process of polishing the lens for spectacles. The abrasive grains are polymeric compounds of a plastic material having a nanometer size. When the abrasive grains are close to each other, they are coagulated and sludgeed, The larger the volume is expanded.

Therefore, when the mixing ratio of the abrasive particles mixed in the polishing wastewater used in the polishing process of the lens is low, the distance between the particles is too long to be dispersed in the polishing wastewater without mutual agglomeration.

On the other hand, when the mixing ratio of the abrasive grains incorporated in the abrasive wastewater increases due to an increase in the number of polished lenses, the distance between the abrasive grains becomes closer to the cohesive distance and coagulates to form sludge. When the sludge agglomeration amount increases, Is swollen and floats on the surface of the polishing wastewater.

The sludge screening network 21 is detachably mounted on a mounting part 203 formed in the water collecting container 20 for collecting sludge generated by polishing wastewater flowing through the water receiving part 201.

The sludge screening network 21 is installed in a removable manner so as to be removably attachable to a receiving part 203 formed in the catching crate 20 in order to selectively discharge the sludge agglomerated and expanded inside the catching cans 20 from the polishing wastewater.

The sludge filtering net (21) has a mesh size that allows abrasive particles mixed in the polishing wastewater collected in the collection container (20) to pass therethrough, while agglomerating the abrasive particles to filter out sludge in the form of lumps.

Therefore, the polishing wastewater flowing into the collection tube 20 is subjected to both coagulation and expansion of the sludge in the sludge filtering net 21 which is disposed in a floating manner in the collection tube 20. Even if the sludge is generated in the sludge filtering net 21, the polishing wastewater flowing through the water intake part 201 formed on the upper part of the water collecting cylinder 20 flows smoothly through the drainage part 202 formed in the lower part of the water collecting cylinder 20 .

Therefore, the sludge screening network 21 mounted on the mounting part 203 formed in the cistern 20 is manually lifted, and the sludge coagulated and expanded inside the sludge screening network 21 is dried by the drying unit 5 It is also possible to insert it into the container 50 manually.

The first ultrasonic oscillator 22 may further include a first ultrasonic oscillator 22 for transmitting high-frequency vibration to the abrasive wastewater collected in the bottom of the water collection tube 20 to improve flocculation of the sludge and prevent clogging of the sludge filtering net 21 have.

That is, when the high-frequency vibration is transmitted to the collection container 20 in a state in which the abrasive wastewater used for a certain period of time is collected in the collection container 20, the high-frequency vibration is transmitted to the abrasive particles mixed in the abrasive wastewater, So that agglomeration between the abrasive particles is activated as the distance between abrasive grains approaches.

Therefore, it is possible for the user to intentionally agglomerate the abrasive grains incorporated into the abrasive wastewater into agglomerated sludge.

When the high-frequency vibration is transmitted to the watercontainer 20 in the state where the abrasive wastewater is collected, the sludge filtering network 21 disposed in the watercount receptacle 20 and the second filter 202a through the sludge filter network 21 and the second filter 202a through the sludge filter network 21 and the second filter 202a by separating and depositing foreign matter adhering to the surfaces of the sludge filter net 21 and the second filter 202a, The passage of the wastewater is smooth, thereby facilitating the repeated use due to the circulation of the filtered water.

And a water pressure sensor 221 may be provided on one side wall of the water collecting container 20 to provide a control unit for controlling the operation of the first ultrasonic oscillator 22 by sensing the water pressure inside the water container.

That is, if the circulation of the water is not smooth due to the increase of the foreign matter adhered to the surface of the sludge filtering net 21 and the surface of the second filter 202a located inside the cistern 20, the water pressure in the cistern 20 increases.

Therefore, when the sensing value sensed by the water pressure sensor 221 and provided to the control unit exceeds the reference value pre-stored in the controller, the controller outputs the operation control signal of the first ultrasonic oscillator 22 to the first ultrasonic oscillator 22 So that the sludge filtering net 21 and the second filter 202a are prevented from being clogged to enable smooth circulation of the filtered water.

The water level sensed by the water level detection sensor 30 can detect the highest water level and the lowest water level, respectively, so that when the highest water level is sensed, the supply of the water is stopped by the controller, and when the lowest water level is sensed, It is preferable that the supply of the constant water is started by the control unit so that the troubles due to replenishment of water can be solved.

In addition, when the highest water level and the lowest water level are detected, it is preferable that the control unit outputs an audiovisual alarm signal according to the water level detection so that the user can recognize it.

There are various methods of detecting the water level, such as a mechanical type using a buoyancy of a ball tower, and an electronic type sensing a water level using a sensor emitting infrared rays. However, due to the characteristics of the sludge agglomerating and expanding in the water cistern 20 It is desirable to use electronic rather than mechanical, which can interfere with water level detection.

The water supply valve 31 connects the supply part side to the water supply line 311 in order to interrupt the supply of the water supplied through the water supply line 311 to the inside of the water storage container 20, The water supply hose 312 connecting the water supply hose 312 connected to the water supply hose 20 is connected to control the supply of clear water from the water supply line 311 to the water storage can 20 along with the opening and closing of the water supply valve 31, As well.

That is, the control unit controls the operation of the water supply valve 31 according to the sensing value provided by the water level sensor 30 installed in the water container 20 to maintain the water level of the water container 20 constant, It is possible to maintain the proper amount necessary for polishing.

It is preferable to use an electronic opening / closing valve that is automatically opened and closed by the control unit, but the present invention is not limited thereto.

The circulation pump 32 is connected to the drainage unit 202 of the watercontainer 20 in order to supply the polishing wastewater filtered in the watercontainer 20 to the indoors, The sludge filtration net 21 disposed in the collection cistern 20 and the second filter 202a disposed inside the drainage portion 202 of the collection cistern 20 are connected to each other by the connection hose connected thereto, Is re-supplied to the furnace through the circulation pump (32).

The circulation pump 32 also functions to regulate the supply pressure and the supply amount at the same time as supplying the filtered water from the collection receptacle 20 to the air humidifier.

Accordingly, the control unit controls the supply amount of the filtered water, which is discharged through the drain part 202 of the water collecting container 20 while being operated by the circulation pump 32 in cooperation with the circulating pump 32, .

It is preferable to use an electronic opening / closing valve that is automatically opened and closed by the control unit, but it should be noted that the filtering water supply valve 33 is not limited to this.
