The operational relationship of the present invention configured as described above will be described with reference to FIGS. 1 to 8 as follows.

First, as shown in FIG. 4 , in a state in which the inlet 31 of the external filter 30 is opened, the blocked part of the inner filter 20 is inserted toward the inner end of the external filter 30 .

Then, in the state in which the upper lid 103 is removed from the upper part of the casing 101, as shown in FIGS. 1, 2 and 5, 6, the filter unit 10 is transferred to the filter inlet 104 formed in the upper lid 103. ) while inserting the fitting hole 32 formed in the inlet 31 of the external filter 30 into the fitting protrusion 105 protruding upward to the outside of the filter inlet 104, the external filter 30 The entrance is opened in the form of a cylindrical tube.

In this state, pull the anti-sag strap 36, the inner end of which is fixed to the inside of the external filter 30, toward the inlet 31, and then insert the hook portion 37 formed at the outer end of the anti-sag strap 36. When inserted into the filter unit (105), the filter unit (10) has a “U” shape because the length of the anti-sag strap 36 is shorter than the overall length of the external filter 30, and the After hanging the hook hole 35 formed at the inner end of the hook 108 installed on the inner wall of the casing 101, the upper lid 103 is closed.

Next, the abrasive water discharge pipe 201 protruding downwardly to the lower side of the spectacle lens polisher 200 while widening the inlet tightening part 21 of the internal filter 20 inserted into the wide opening of the external filter 30. When the drawstring 22 is tightened after being inserted outside, the internal filter 20 is connected to the grinding water discharge pipe 201, and the entire length of the filter unit 10 is longer than the inner width of the casing 101, so the filter unit 10 is Overall, the "U" shape is drooping, and the lower part of the filter unit 10 drooping in the "U" shape is placed on the support frame 107 in the form of a mesh installed inside the casing 101 .

At this time, the upper part of the external filter 30 is shorter than the length of the external filter 30 by the anti-sag strap 36 installed on the inner upper part of the external filter 30 , so the external filter 30 mounted on the abrasive water treatment device 100 . ) of the upper and lower parts of the casing 101 is opened inside the state.

When the filter unit 10 is installed in the abrasive water treatment device 100 in this way, the user can use the sewing line display part 39 installed on the sewing line 38 of the external filter 30 to face upward, as shown in FIGS. 1 and 3 . do. This is to prevent the lens powder (sludge: 10a) particles generated when grinding the spectacle lens through the small gap formed by the sewing line 38 from leaking out.

Glasses in a state in which the filter unit 10 is mounted on the polishing water treatment device 100 as above, and the internal filter 20 included in the filter unit 10 is connected to the polishing water discharge pipe 201 of the spectacle lens polisher 200 When power is supplied to the lens polishing machine 200, the polishing motor 202 of the spectacle lens polishing machine 200 drives and the polishing machine installed on the motor shaft rotates interlockingly and at the same time, it is polished by driving a circulation pump (not shown). Water is supplied to the grinding machine side.

In addition, the control unit 102 of the abrasive water treatment apparatus 100 is operated to input the number of dimensions to be processed in a state in which power is supplied.

In this state, after cutting the spectacle lens into a desired shape in the spectacle lens polisher 200, the cut surface of the spectacle lens is polished. They are mixed together and discharged to the polishing water discharge pipe (201).

At this time, the internal filter 20 included in the filter unit 10 is connected to the grinding water discharge pipe 201 so that the abrasive powder particles and abrasive water (hereinafter referred to as abrasive mixture) flow into the internal filter 20 . However, the inner filter 20 is opened only at the inlet side and the inner end is formed in the form of a clogged bag, so that the abrasive mixture is contained in the inner filter 20 .

When the abrasive mixture is introduced into the inner filter 20 in this way, the filter unit 10 is installed to be suspended in a “U” shape and the anti-sag strap 36 is installed therein. The upper inlet side becomes open without sticking inward, so that the inflow of the abrasive mixture becomes smooth, and the filter unit including the internal filter 20 ( 10) is drooping down, but the filter unit 10 is not stretched or damaged because the lower part of the filter unit 10 is supported on the support frame 107 in the form of a mesh.

In this state, when the abrasive mixture is introduced into the inner filter 20, it is a fine void formed in the fabric of the inner filter 20 manufactured in the form of a sack as a fabric paper. Most of the abrasive powder in the abrasive mixture (sludge: 10a) Silver is caught on the inside of the inner filter (20) and does not escape into the voids, and the grinding water escapes under the inner filter (20).

And, as shown in FIG. 6, a ventilation part 33 is formed at the inner end of the external filter 30 so that when the abrasive mixture flows into the internal filter 20, air is introduced together with the internal filter 20. As the fabric bag is formed, the ventilation part 33 is opened at the inner end of the external filter 30 so that the air flowing into the internal filter 20 is exhausted to the outside of the internal filter 20, followed by the ventilation part It is exhausted to (33) so that the abrasive mixture is smoothly introduced into the inner filter (20).

As above, the abrasive water flowing out below the inner filter 20 contains a very small amount of abrasive powder particles. As the (10b) is contained inside the external filter 30, the second filtration is made.

At this time, since the external filter 30 is made of multiple layers of fabric paper, the passing amount of the abrasive powder particles is minimized every time it passes through the multiple layers of fabric, and the abrasive water 10b is formed on the multiple layers of fabric. As it passes through the micropores and leaks to the lower side of the external filter 30, it is contained in the inner space of the casing 101. The abrasive water leaked to the lower side of the external filter 30 and filtered is referred to as filtered water 10c. .

As above, when the water level of the filtered water 10c contained in the casing 101 rises and reaches the height set in the water level sensor 109, the pump 110 is operated to remove the filtered water 10c contained in the casing 101. It is discharged to the outside through the discharge hose 111, and the control unit 102 outputs the discharged state of the filtered water as an audio signal, so that the user can easily know the discharged state of the filtered water.

Through this process, up to the lens polishing quantity is displayed on the character display unit of the control unit 102 by the setting signal with the spectacle lens polishing machine 200, and when the set quantity is reached, a voice signal is emitted and the polishing water treatment device 100 After stopping the operation of the spectacle lens polisher 200, the filter unit 10 is separated from the casing 101, the sludge contained in the inner filter 20 is taken out and discarded, and the inner filter 20 and the outer filter (30) is washed and reused.

And, in the overflow pipe 114 included in the present invention, when an abnormal situation occurs that the pump 110 installed inside the casing 101 does not operate, the water level of the filtered water contained in the casing 101 is at a certain height. When it is reached, it overflows.

In addition, the lower drain port 113 facilitates the cleaning operation by discharging the filtered water contained in the inner side of the casing 101 when the valve 112 is opened when cleaning the abrasive water treatment device 100 . , the water level indicator 115 is a transparent body vertically installed on the outside of the casing 101 so that the lower end communicates with the inside of the casing 101, the water level and the degree of turbidity of the filtered water 10c visible inside the transparent body of the water level indicator 115 you can see it with the naked eye

Next, this embodiment of the abrasive water treatment apparatus 100 shown in FIG. 7 will be described, which shakes the lower part of the filter unit 10 in the embodiment shown in FIG. 1 as described above. ), the abrasive water contained in the abrasive mixture flowing into the inside of the filter unit 10 quickly leaks out of the oscillating means 40 is added, so the description of the same part as in one embodiment is omitted and added. Only the rocking means 40 will be described in detail.

In the case of one embodiment, as the filter unit 10 is stopped in a state of being placed on the support frame 107, the time for which the grinding water is discharged from the internal filter 20 and the external filter 30 to the lower side is delayed, so that the lens polishing is continuously performed. There may be a fear that the grinding water may flow back from the grinding water discharge pipe 201 of the spectacle lens polisher 200 due to excessive discharge of the grinding water, in this embodiment, the filter unit 10 as a rocking means 40 As the abrasive is shaken, the abrasive powder particles contained in the inner filter 20 do not agglomerate and form a gap, thereby shortening the discharge time of the abrasive water.

That is, when the cam 46 installed on the motor shaft rotates by the driving of the motor 45 installed on the support bracket 106 , the cam 46 rotates together with the cam 46 . ), the cam guide part 44 with the lower end resting on the upper surface rises and descends according to the eccentric curvature of the cam, and the upper part of the cam guide part 44 is guided to the column guide part 107a of the support frame 107. 43) is installed vertically, and at the upper end of the column 43, a plate-shaped support 42 located above the bottom surface of the support frame 107 supports the bottom of the filter unit 10, so that the motor 45 is driven. The operation of repeatedly pushing up and lowering the lower part of the filter unit 10 is repeated.

As the plate-shaped support 42 repeatedly ascends and descends as described above, the abrasive mixture contained in the inner filter 20 oscillates and the abrasive powder particles are separated from each other without agglomeration. The stagnant time in the filter 20 and the time the grinding water is discharged to the outside of the inner filter 20 are shortened, and the stagnation and discharge time of the grinding water inside the external filter 30 is also shortened.

The external filter 30 shown in FIG. 8 is formed so as to leave a gap between the multi-ply fabrics 30a constituting the external filter 30 . The abrasive mixture discharged to the lower side of the inner filter 20 contains a very small amount of abrasive powder particles. Since a water film is formed on the outer filter 30, the stagnant time and the discharge time of the polishing water contained in the inside are delayed, but in this embodiment, the multiple-ply fabric paper 30a is spaced apart, so that the polishing water is stagnant and discharged. The time is shortened so that the abrasive mixture can be effectively treated.

And, in the present invention, the external filter 30 is formed by combining a plurality of fabric paper 30a cut into a square by sewing each individually in the longitudinal direction to form several fabric paper tubes with both ends open, and then each of the fabric paper tubes. After inserting the fabric paper tube, both ends of the fabric paper tube fitted in multiple layers are joined by sewing to form a sack shape with an open mouth. When introduced, each of the fabric paper tubes can move in all directions, thereby minimizing clogging of the pores forming the fabric paper tube, thereby allowing the abrasive water to easily leak out.
