The operation panel 35 such as 1 has an operation knob 36 as shown in FIG. The operation knob 36 operates the rotary switch 37 shown in FIG. The ON / OFF signal of the rotary switch 37 is input to the arithmetic control circuit 38. Further, the sensors S1, S2, S3
Are also input to the arithmetic and control circuit 38.

The solenoid valves V1 to V4 and the pumps 15 and 2
The operations of 0, 21 and the like are controlled by the arithmetic and control circuit 38. [Operation] Next, a processing method of the grinding water processing apparatus of the lens grinding apparatus having such a configuration will be described. (1) Grinding of lens to be processed and cooling of grinding part In the lens grinding device 1, the grinding wheel 5 is driven to rotate, and the rotation control and the elevation control of the lens rotating shafts 3, 3 are performed based on the lens shape data. Thus, the peripheral portion of the lens 4 to be processed held between the lens rotation shafts 3 and 3 is ground into a lens shape by the grinding wheel 5. Since this processing method can be performed using a known technique, a detailed description thereof will be omitted.

At the time of this grinding, the pumping pump 15 is operated to pump up the grinding water 13 stored in the grinding water tank 10 from a relatively clear upper portion via the filter 17 and the pipe 16. This pump 1
The grinding water pumped up by the nozzle 5 is blown from a nozzle 6 through a pipe 18 to a grinding portion of the lens 4 to be processed by the grinding wheel 5 as cooling water, thereby cooling the grinding portion and simultaneously grinding the grinding wheel 5 of the lens 4 to be processed. Rinse the grinding debris. The grinding debris washed away by this is drained into the grinding water tank 10 via the hose 12 together with the cooling water. (2) Deodorization (removal of odor) By the way, when the lens 4 to be processed is a plastic lens, when the plastic lens is ground with the grinding wheel 5, the nose is affected by sulfur molecules contained in the plastic lens. An odor such as an unpleasant odor or an unpleasant odor is generated. The air containing this odor is dissolved in the cooling water used when grinding the lens 4 to be processed, and is allowed to flow down into the grinding water tank 10 through the hose 12 together with the cooling water, or to the cooling water flowing down. It is caught and flows down into the grinding water tank 10.

Therefore, in order to remove the odor flowing down into the grinding water tank 10 during the grinding of the lens 4 to be processed, the electric fan (not shown) of the deodorizing device 9 is operated to operate the space 1.
The air containing the odor is removed from the deodorizing device 9 through the pipe 34
Let it suck inside. Then, the odor is deodorized from the air containing the odor with a deodorizing material (deodorant), and the odorless air is discharged to the atmosphere. (3) Filtration of grinding water When the operation knob 36 in FIG. 2 is at the center OFF position as shown in FIG. 2, the pumps 20 and 21 and the solenoid valves V1 to V
4 is in an OFF state. When the operation knob 36 is turned to the position of “filtration”, the arithmetic and control circuit 38 operates the pumps 20 and 21. At this time, the arithmetic control circuit 38
Controls the operation of the solenoid valves V1 and V3 to the open state,
The operation of the solenoid valves V2 and V4 is controlled to be closed.

In this state, the first pump 20 sucks the grinding water 13 containing the grinding chips in the grinding water tank 10 through the pipe 26 as shown by an arrow 50 in FIG. The discharged grinding water passes through the pipe 27, the branch pipe portion 27a, the solenoid valve V1, and the pipe 29 as indicated by an arrow 51, and the grinding dust collecting bag 23 and the filter 2 are removed.
5 is caused to flow into the grinding waste chamber A as indicated by an arrow 52.

The inflowing grinding water is filtered by the filtration filter 25.
Through the filter water chamber B as shown by the arrow 53. At this time, the grinding waste contained in the grinding water is collected on the outer surface of the filtration filter 25 and settles at the bottom of the grinding waste chamber A. Further, the grinding water that has flowed into the filtered water chamber B and is cleaned is supplied to the pipe 33, the solenoid valve V3, and the branch pipe section 32 as indicated by an arrow 54.
a, After being sucked into the second pump 21 via the pipe 32, it is discharged into the grinding water tank 10 via the pipe 31 at the bottom side as indicated by an arrow 55.

When such filtration is performed, for example, for about one hour,
The filter 25 is clogged. That is, when the filtration filter 25 is clogged, the level of the grinding water in the grinding waste chamber A rises. When the liquid level a further rises from the position of the sensor S3, the sensor S3 rises together with the liquid level a, and when the liquid level a reaches the same height h1 as the lower end of the pipe 29, the height h1 Position of sensor S
3 detects. At this time, the height detection signal output from the sensor S3 is input to the arithmetic and control circuit 38. Then, the arithmetic and control circuit 38 stops the pump 20 when the liquid level a comes to the position of the height h1 according to the detection signal from the sensor S3. Note that the sensor S3 may be omitted.

In the filtration state where the pumps 20 and 21 are operating, the arithmetic and control circuit 38 has the sensor S
1 is input. The arithmetic and control circuit 38 controls the liquid level 1 of the grinding water 13 in the grinding water tank 10.
3a descends from the upper limit position of the sensor S1 together with the liquid level 13a, and the liquid level 13a becomes the height h of the lower end of the pipe 26.
When the second pump 20 is detected based on the detection signal from the sensor S1, the first pump 20 is stopped. (4) Backwashing of the filter 25 When the pump 20 is stopped in this way, the filter 2
Since 5 is clogged, in this case, the operation knob 36 is rotated to the "backwash" position. As a result, the arithmetic and control circuit 38 operates the pumps 20 and 21 and controls the operation of the solenoid valves V1 and V3 to be closed.
The operation of the solenoid valves V2 and V4 is controlled to open.

In this state, the first pump 20 supplies the grinding water 13 in the grinding water tank 10 through the pipe 26 as shown in FIG.
, And is discharged to the pipe 27.
The discharged grinding water is supplied to the pipe 27, the branch pipe 27b, the solenoid valve V3 and the pipe 30 as indicated by the arrow 51.
Through the filter water chamber B in the filtration filter 25 as indicated by an arrow 56.

The inflowing grinding water is filtered by the filtration filter 25.
Penetrates as indicated by an arrow 57 and flows into the grinding waste chamber A. At this time, the grinding water causes the grinding dust adhering to the outer surface of the filtration filter 25 to be separated from the outer surface of the filtration filter 25 and settled downward. The grinding water flowing into the grinding waste chamber A is supplied to the pipe 34, the solenoid valve V4, and the branch pipe section 3 as indicated by an arrow 58.
2b, after being sucked into the second pump 21 through the pipe 32, it is discharged through the pipe 31 into the grinding water tank 10 at the bottom side as indicated by an arrow 55. Such back washing is performed, for example, for about one minute.

Also in this case, the arithmetic control circuit 38 controls the sensor S
The pump 20 is stopped when the liquid level a reaches the position of the height h1 according to the detection signal from 3. (5) Dehydration After such filtration and backwashing are repeated, when a certain amount of grinding dust is collected in the grinding dust collecting bag 23, the operation knob 36 is rotated to the "dewatering" position. Let it.
Thereby, the arithmetic and control circuit 38 stops the first pump 20 and activates the second pump 21, and controls the operation of the solenoid valves V 1, V 2 and V 4 to be closed, and
The operation of the solenoid valve V3 is controlled to the open state.

In this state, the operation of the second pump 21 causes the grinding water in the filtered water chamber B to flow through the pipe 3 as indicated by the arrow 54.
3. After being sucked into the second pump 21 through the solenoid valve V3, the branch pipe portion 32a, and the pipe 32, it is discharged through the pipe 31 into the grinding water tank 10 at the bottom side as indicated by an arrow 55.

By the operation of the second pump 21 as described above,
When the liquid level b of the grinding water in the filtered water chamber B drops and the liquid level b reaches the position of the sensor S2, the sensor S2 also drops integrally with the liquid level b. At this time, the detection signal from the sensor S2 is input to the arithmetic and control circuit 38. And the arithmetic control circuit 38
Is based on the detection signal from the sensor S3, the liquid level b
When the second pump 2 is lowered to the height h3 at the lower end of the second pump 2
1 is stopped.

Thereafter, the lid 24 is removed, the filtration filter 25 and the sensors S2 and S3 are removed from the filtration tank 22, and the grinding debris collection bag 23 is removed from the filtration tank 22 to collect grinding debris. It can be taken out of the filtration tank 22 together with the bag 23 and processed. (6) Other Configurations and Advantages of the Above-described Apparatus The lens waste in the processing wastewater is automatically separated and only the lens waste can be separated and discarded without soiling the hands.・ By constantly cleaning and circulating processing wastewater,
Keeps the lens and processing chamber clean.・ Eliminates odor from processing wastewater and does not cause discomfort.・ Assist the disposal system of lens wastewater so as not to harm the environment.・ Water is saved because the processing drain tank is not frequently cleaned. [1]. Various configurations can be adopted for the filtration filter 25. [2]. The filtering filter 25 may be made of a petroleum-based fiber, and a filter material having a configuration in which the density of the fiber is made to be uniform and the porosity and the thickness thereof may be a laminated flat plate. [3]. The filtration filter 25 is provided with a container having a porous surface, and the filter material of [2] is tightly wound around the entire surface of the container, and when the waste liquid is pressed from the outer surface to the inner surface, [2] ], The sludge layer may be laminated as a filtration membrane while leaving the liquid passage on the surface of the filter material. [Four]. A configuration may be adopted in which the sludge laminated in [3] is jetted backward from the inner surface of a container having a closed porous surface with a pressurized filtrate to remove the sludge layer attached to the filter material. [Five]. The outside of the closed container formed of a plate having a porous surface may be stored in a vinyl or film bag. [6]. A guide container is provided in the vinyl bag shape of [5] so that the sludge that has been backwashed and peeled off in [4] can be stored, and the inner surface of the container is made to have a negative pressure by the method of [3]. The dewatered sludge may be stored. [7]. Eyeglass lens grinding water storage container (grinding water tank 1
0) and the filtration tank 22 are connected to the phone 20,
The pipe is arranged so that it can be circulated at 21. [8]. Then, the circulating grinding fluid becomes clear water while the circulation function is repeated several times while the filtering function of [3] works effectively. [9]. In this apparatus, a pump 20 for supplying water to the outside of a container (filtration filter 25) formed of a perforated plate and a pump 21 for draining grinding water inside the container (filtration filter 25) are provided. [Ten]. By providing the pump 20 for water supply and the pump 21 exclusively for drainage, even if a certain amount of filter clogging occurs, the circulation of water can be facilitated without a sudden decrease in the flow rate. [11]. The operations of [4] and [6] are performed by the solenoid valve V1 as described above.
By using V4, the flow of water can be automatically switched. [12]. The grinding water (drainage) in the grinding water tank 10 is branched by pumps 20 and 21, respectively, and a large area in the tank 10 is efficiently sucked by the pumps 20 and 21.
Since the drainage from 0 has a function of stirring the inside of the tank 10, the sludge (grinding waste) in the tank 10 can be sent to the filtration tank 22 without settling on the bottom surface of the tank 10. [13]. This series of mechanisms can be built in a dedicated table of the processing machine. [14]. When the inside of the filtration tank 22 reaches a certain water level so as not to be full, it has a function of detecting and stopping the pump 20. [15]. At the time of backwashing, since the water is supplied into the filtration tank from the pump side, it has the function of detecting when a certain water level is reached and stopping the pump.

Second Embodiment In the first embodiment of the present invention described above, grinding water discharged from the first pump 20 to the pipe 27 is supplied to the grinding waste chamber A and the filtered water chamber via the solenoid valves V1 and V2. B, the grinding water in the grinding waste chamber A and the filtration water chamber B is sucked into the second pump 21 via the solenoid valves V3, V4 and the pipe 32, but is not necessarily limited to this configuration. It is not something to be done.

For example, as shown in FIG.
Is inserted into the grinding waste chamber A such that the lower end is located at the upper part, and the filtered water chamber B is inserted such that the lower end is located near the bottom part.
And the arithmetic and control circuit 38
The suction and discharge directions of the second pumps 20 and 21 may be controlled. In this embodiment, the solenoid valves V1 to V1
The configuration other than the elimination of V4 and the functions of grinding and deodorization are the same as those of the first embodiment of the present invention, and a description thereof will be omitted. (I) Filtration of Grinding Water When the operation knob 36 in FIG. 2 is at the center OFF position as shown in FIG. 2, the pumps 20 and 21 are in the OFF state. When the operation knob 36 is turned to the position of “filtration”, the arithmetic and control circuit 38 operates the pumps 20 and 21.

At this time, the arithmetic and control circuit 38 controls the operation of the first pump 20 to connect the grinding water tank 1 with the pipe 26.
The grinding water in 0 is sucked into the first pump 20 as indicated by an arrow 66, and the grinding water is discharged to the pipe 27. The discharged grinding water flows into the grinding waste chamber A between the grinding waste collecting bag 23 and the filtration filter 25 via the pipe 27 as shown by an arrow 60.

The flowing grinding water is filtered by the filtration filter 25.
Through the filter water chamber B as shown by the arrow 61. At this time, the grinding waste contained in the grinding water is collected on the outer surface of the filtration filter 25 and settles at the bottom of the grinding waste chamber A.

Further, the arithmetic and control circuit 38 controls the operation of the second pump so as to flow the purified grinding water flowing into the filtered water chamber B through the pipe 32 as shown by an arrow 62 in the second pump 21. Then, it is discharged into the grinding water tank 10 through the pipe 31 at the bottom side as shown by the arrow 55.

When such filtration is performed, for example, for about one hour,
The filter 25 is clogged. That is, when the filtration filter 25 is clogged, the level of the grinding water in the grinding waste chamber A rises. When the liquid level a further rises from the position of the sensor S3, the sensor S3 rises together with the liquid level a, and the liquid level a becomes the same height h1 as the lower end of the pipe 27 in the grinding chamber A. Next, the sensor S3 detects the position of the height h1. At this time, the height detection signal output from the sensor S3 is calculated by the arithmetic control circuit 38.
Has been entered. Then, the arithmetic and control circuit 38 stops the pump 20 when the liquid level a comes to the position of the height h1 according to the detection signal from the sensor S3.

In the filtration state in which the pumps 20 and 21 are operating, the arithmetic and control circuit 38 has the sensor S
1 is input. The arithmetic and control circuit 38 controls the liquid level 1 of the grinding water 13 in the grinding water tank 10.
3a descends from the upper limit position of the sensor S1 together with the liquid level 13a, and the liquid level 13a becomes the height h of the lower end of the pipe 26.
When the second pump 20 is detected based on the detection signal from the sensor S1, the first pump 20 is stopped. (Ii) Backwashing of the filtration filter 25 (see FIG. 7)
