It is designed to be supplied to 1a.

Further, a timer T is attached to the upper wall 40b of the main body case 410, and the time set by the timer T is the filtration processing time. [Operation] Next, the operation of the lens grinding apparatus 1 and the grinding water treatment apparatus having the above-described configurations will be described. (A) Grinding Water Circulation during Grinding When grinding is performed by the lens grinding device 1, first, the opening / closing valve 47 is opened by operating the opening / closing operation lever 47b to connect the grinding water supply hose 30 to the water supply port 15. The open / close valve 50 is opened by operating the open / close operation lever 45b, the open / close valve 90 is opened by operating the open / close operation lever 90b, and the drain hose 31 is connected to the drain ports 16 and 16 '. On the other hand, the open / close valve 49 is operated by operating the open / close operation lever 49b.
The air discharge side of the air compressor 20 and the water supply port 1
Block communication with 5.

Next, the control panel (not shown) of the lens grinding apparatus 1 is operated to rotate the grinding wheel 1b at a high speed, and the lens to be processed is ground into the lens shape (eyeglass shape) of the eyeglass by the grinding wheel 1b. To process. On this occasion,
The control device 76 receives the grinding start signal from the lens grinding processing device 1 and operates the grinding water supply pumps 24 and 25.

As a result, the grinding water chamber 3 of the grinding water tank 3
The grinding water in a is pumped up by the grinding water supply pump 24 as shown by the arrow A1 in FIG. 9 (see FIG. 10),
It is supplied to the nozzle 1 a in the lens grinding processing apparatus 1 via the grinding water supply hose 26. Then, as shown in FIG. 9, the grinding water is sprayed from the nozzle 1a toward the grinding portion A by the grinding wheel 1b of the lens L to be processed, and the grinding portion A
Cooling and flushing of grinding debris. In this way, the grinding water from which the grinding dust has been washed away is caused to flow down from the bottom of the lens grinding apparatus 1 through the drain hose 19 into the drainage chamber 3b of the grinding water tank 3 together with the grinding dust as shown by the arrow A2. (See Figure 10).

On the other hand, the grinding water supply pump 25 sucks the grinding water in the drainage chamber 3b of the grinding water tank 3 together with the grinding waste, and the grinding water containing the grinding waste is supplied as shown by an arrow A3. It is supplied into the grinding dust separation filter 10 through 30, the on-off valve 47 and the water supply port 15 (see FIG. 10).

The grinding water is filtered and separated by the grinding dust separating filter 10 and flows down to the bottom side of the separation container body 9. The grinding water separated in this separation container 9 is discharged from the drain port 1
6, connection pipe 1 through drain pipe 16c and on-off valve 50
While being guided to 6b, drain port 16 ', drain pipe 16

), And is sucked into the grinding water supply pump 24 and circulated.

Incidentally, the grinding waste separation filter 10 is clogged by such grinding, and the grinding water returned to the grinding water chamber 3a of the grinding water tank 3 through the drainage port 16 and the drainage hose 31. Even if the amount decreases, the grinding water in the drainage chamber 3b passes through the partition filter 23 and flows into the drainage chamber 3a,
Since it is discharged from the grinding water supply pump 24 and circulated,
It does not interfere with flushing and cooling of grinding dust. (B) Deodorization Further, the slide lid 1c of the lens grinding processing device 1 is slid upward to open the processing chamber 1d of the lens grinding processing device 1, and the lens to be processed is inserted between the lens rotation shafts 1e and 1e in the processing chamber 1d.

Moreover, the air containing odor in the upper space of the grinding water chamber 3a is sucked into the deodorizing device main body 52 via the air hoses 46a and 69, and the filter 64 and the activated carbon 63 are discharged.
Exhausted from the blower 53. At this time, bubbles of grinding water and grinding debris contained in the air are collected by the filter 64, the odor contained in the air that has passed through the filter 64 is adsorbed by the activated carbon 63, and the air from which the odor has been removed is blower 5
It is exhausted from 3 to the atmosphere.

Therefore, the processing chamber 1 of the lens grinding processing apparatus 1
Since the odor generated in c does not leak to the outside, it is possible to prevent the operator from feeling uncomfortable.

Since the inside of the transparent air hose 69 can be visually confirmed through the transparent cover 71 of the window 70, even if the bubbles of the grinding water generated in the grinding water chamber 3a are sucked into the air hose 69 together with the air, the air hose 69 The state of bubbles of grinding water can be confirmed in 69. As a result, when there are many bubbles of grinding water, deodorizing is affected, so the deodorizing device main body 52 is taken out and the filter 64 is replaced, or the air hose 6 is used.
It is possible to easily know the timing of the work of removing the grinding water from the air hose 69 by removing 9.
