  Next, the operation of the grinding water treatment apparatus of the present invention will be described.

  In order to use this grinding water treatment apparatus, first, the lever 56a is opened to open the water supply opening / closing valve 56, and water is supplied to the grinding water tank 20 from a water supply (not shown) through the water supply pipe 55.

  At this time, since the grinding start switch (not shown) of the lens grinding apparatus 10 is turned off, the solenoid valve 47 closes the grinding water supply hose 54 side to allow the filtered grinding water supply pipe 42 and the circulation pipe 46 to communicate with each other. So that it is controlled.

  The used grinding water on-off valve 32 and the filtered grinding water on-off valve 43 are opened in advance, and the air on-off valve 52 and the drain on-off valve 45 are closed in advance.

  And the water which flowed out from the outlet 55b of the water supply pipe 55 is stored in the grinding water tank 20, and when this grinding water tank 20 becomes full, the drive switch of the lens grinding apparatus 20 is turned ON.

  When the drive switch of the lens grinding apparatus 20 is turned on, the drive switch of the pump 30 is turned on in conjunction with it. Then, the pump 30 starts to be driven, and the pump 30 sucks the water stored in the grinding water tank 20 from the intake port 23 of the water collecting pipe 21 connected to the suction part 30a, and uses the used grinding water from the discharge part 30b. The water sucked through the supply pipe 31 is caused to flow into the filtering device 40.

  The water that has flowed to the filter device 40 passes through the filter device 41 and flows downward, and then flows from the water inlet 42 a of the filtered grinding water supply pipe 42 to the filtered grinding water supply pipe 42.

  Then, the water flowing through the filtered grinding water supply pipe 42 flows to the circulation pipe 46 and enters the grinding water tank 20 by an electromagnetic valve 47 controlled so as to communicate the filtered grinding water supply pipe 42 and the circulation pipe 46. Return.

  When the water stored in the grinding water tank 20 returns to the grinding water tank 20 again via the pump 30, the filtering device 40, and the filtered grinding water supply pipe 42, the lever 56a is closed and the water supply on / off valve is closed. 56 is closed. Thereby, the supply of water from the water supply is stopped.

  Next, the grinding start switch (not shown) of the lens grinding apparatus 10 whose drive switch is turned on is turned on to start the lens grinding process.

  In conjunction with the ON operation of the grinding start switch, the solenoid valve 47 is controlled to open and close, the circulating pipe 46 side is closed, and the filtered grinding water supply pipe 42 and the grinding water supply hose 54 are communicated.

  Then, a grinding wheel (not shown) of the lens grinding apparatus 10 is rotated at high speed, and the lens to be processed is ground into the lens shape (lens shape) of the glasses by the grinding wheel. At this time, the water in the filtered grinding water supply pipe 42 is supplied into the lens grinding apparatus 10 via the grinding water supply hose 54, and the grinding part for grinding the lens to be ground is cooled and the grinding waste is washed away.

  As described above, before the grinding start switch of the lens grinding apparatus 10 is turned on, water is supplied to the pump 30, the filtering device 40, and the filtered grinding water supply pipe 42 in advance, and the water in the filtered grinding water supply pipe 42 is discharged. Since it is supplied to the lens grinding apparatus 10, it becomes possible to supply the grinding water immediately and the grinding process can be started smoothly.

  Then, the used grinding water supplied to the grinding unit to wash away the grinding scraps contains grinding scraps, wrinkles, foams, and the like, and flows down toward the grinding water tank 20 through the grinding water drain hose 11 together with these. .

  Here, since the discharge port 12 of the grinding water drain hose 11 faces above the intake opening 22 a of the funnel 22, the used grinding water including grinding debris and the like is taken in without being returned to the grinding water tank 20. It is taken into the funnel 22 through 22a.

  Thereby, it is possible to prevent the used grinding water from becoming turbid with the water stored in the grinding water tank 20.

  The used grinding water taken into the funnel 22 is sucked into the pump 30 through the water collecting pipe 21 and further discharged from the pump 30 into the filtering device 40 through the used grinding water supply pipe 31.

  The used grinding water discharged into the filtration device 40 is discharged from the discharge port 31 a of the used grinding water supply pipe 31 facing the upper portion of the filter device 41 and passes through the filter device 41.

  At this time, the grinding waste contained in the used grinding water is collected by the filter device 41, and the used grinding water is filtered to become filtered grinding water containing no grinding waste.

  Then, the filtered ground water flows down from the lower part of the filter device 41, flows through the filtered ground water supply pipe 42 from the water inlet 42 a located below the filter device 41, and again through the ground water supply hose 54. Supplied to the lens grinding apparatus 10.

  When the lens grinding process is completed, the grinding start switch of the lens grinding apparatus 10 is turned off. The electromagnetic valve 47 is interlocked with the OFF operation of the grinding water start switch, and the grinding water supply hose 54 side is closed to allow the filtered grinding water supply pipe 42 and the circulation pipe 46 to communicate with each other.

  Therefore, the filtered grinding water in the filtered grinding water supply pipe 42 is supplied so as to return to the grinding water tank 20 from the circulation pipe 46.

  Thus, the used grinding water used for the lens grinding process is filtered through the filtering device 40 without returning to the grinding water tank 20, and this filtered filtered grinding water is filtered through the filtered grinding water supply pipe 42. Then, water is again supplied to the lens grinding apparatus 10 to continuously perform the lens grinding process. At the end of the lens grinding process, the filtered grinding water is supplied from the filtered grinding water supply pipe 42 to the grinding water tank 20 through the circulation pipe 46.

  That is, the filtered grinding water supply pipe 42 and the circulating pipe 46 serve as a circulating means for supplying the filtered grinding water filtered by the filtering device 40 to the lens grinding apparatus 10 or the grinding water tank 20.

  Finally, the drive switch of the lens grinding apparatus 10 is turned off, and in conjunction with this, the drive switch of the pump 30 is also turned off.

  When a large amount of grinding debris is collected in the filter device 41 in the filtration device 40 during or after the grinding process, the grinding start switch of the lens grinding device 10 is first turned off.

  Next, the lever 32a is closed to close the used grinding water on-off valve 32, and the lever 43a is closed to close the filtered grinding water on-off valve 43. Further, the lever 52a is opened to open the air on / off valve 52, and the lever 45a is opened to open the drain on / off valve 45.

  At this time, the lens grinding device 10 and the drive switch of the pump 30 may be turned on or off.

  Then, the air compressor 50 is operated, and compressed air is supplied to the upper side of the filter device 41 from the discharge port 31 via the air hose 51 and the air opening / closing valve 52. Thereby, the retained grinding water retained on the upper part of the grinding waste of the filter device 41 passes through the grinding waste collected by the pressure of the air and the filter device 41 and is discharged from the water suction port 42a.

  The retained grinding water discharged from the water inlet 42a is discarded from the drain pipe 44 into the sewer. In this way, after the flow of the retained grinding water almost disappears from the water inlet 42a, the operation of the air compressor 50 is stopped, the filter device 41 arranged inside the filtration device 40 is taken out, and the collected grinding scraps are collected. Is disposed of as industrial waste.

  As described above, in the grinding water treatment apparatus of the present invention, the used grinding water used by the lens grinding apparatus 10 is passed through the filtration device 40 which is a grinding water treatment means and is filtered by the filtration device 40. A filtered grinding water supply pipe 42 and a circulation pipe 46, which are circulation means for supplying filtered grinding water to the grinding water tank 20 or the lens grinding apparatus 10, are provided.

  Therefore, the flow paths of the used grinding water and the filtered grinding water are not the same, and it is possible to reliably prevent the used grinding water and the filtered grinding water from becoming turbid. And it becomes possible to fully filter used grinding water.

  Further, the water flow from the grinding water tank 20 to the filtration device 40 can be controlled by a single pump 30, and the used grinding water can be sufficiently filtered with a simple configuration.

  Further, the filtered grinding water supply pipe 42 and the grinding water supply hose 54 are connected via a constant flow valve 53, and an electromagnetic valve 47 linked to the ON / OFF operation of the grinding start switch of the lens grinding apparatus 10 is provided. Since it is provided and the flow path is switched, it is possible to always maintain the circulation amount of the grinding water. Then, the filtered ground water that has been sufficiently filtered can be easily used for the grinding process again, and the lens grinding process can be performed smoothly.

  The flow rate of the filtered grinding water flowing through the grinding water supply hose 54 can be made constant by the constant flow valve 53, and the filtered grinding water supplied to the lens grinding apparatus 10 can be made constant. Thereby, the lens grinding process by the lens grinding apparatus 10 can be performed stably.

  Further, in the conventional grinding water treatment device, the grinding water circulates only in the closed flow paths only between the lens grinding device and the grinding water tank and only between the grinding water tank and the filtration device. However, in the grinding water treatment apparatus of the present invention, water flows from the grinding water tank 20 to the filtration device 40 via the pump 30, and lens grinding is performed from the filtration device 40 via the filtered grinding water supply pipe 42 which is a circulation means. Grinding water is supplied to the apparatus 10.

  Therefore, it is possible to always use the filtered grinding water again for the lens grinding process and to circulate the used grinding water to the filtering device 40. Therefore, water can be supplied directly as grinding water from the water supply, and filtered filtered grinding water can be drained directly into the sewer.

  As a result, water was directly supplied from the water supply to the grinding water tank 20 via the water supply pipe 55, and the filtered ground water filtered by the filtration device 40 was directly drained to the sewer via the drainage pipe 44.

  Then, water supply from the water supply and drainage to the sewer can be easily performed, and the lens grinding process can be performed more smoothly.

  Although one embodiment according to the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to the above-described embodiment. Design changes and the like within the scope not departing from the gist of the present invention are included in the present invention.

  For example, in the above-described embodiment, the pump 30 is provided on the water supply side of the filtration device 40, but the pump 30 may be provided on the drain side of the filtration device 40 as shown in FIG.

  In this case, the other end 21 a of the water collecting pipe 21 is connected to the filtration device 40. The pump 30 and the filtering device 40 are connected via a communication pipe 60.

  The other end 21 a of the water collecting pipe 21 faces the upper part of the filter device 41. A suction port 60 a formed at one end of the communication pipe 60 is located below the filter device 41, and the other end is connected to the suction portion 30 a of the pump 30.

  Furthermore, the discharge part 30 b of the pump 30 is connected to the water inlet 42 a of the filtered ground water supply pipe 42.

  With such a configuration, the pump 30 is supplied with the filtered grinding water filtered by the filtering device 40, so that the pump 30 is not clogged with clogged grinding dust or the like. And grinding water can be circulated smoothly.

  Here, a dewatering pipe 61 is connected to the lower part of the filtering device 40. The dewatering pipe 61 communicates with the drainage pipe 44, and can be drained by directly flowing filtered ground water from the dewatering pipe 61 to the drainage pipe 44 without passing through the pump 30.

  In order to allow the filtered ground water to flow from the dewatering pipe 61 to the drainage pipe 44 without passing through the pump 30, the dewatering on / off valve 62 provided at the intermediate portion of the dewatering pipe 61 is opened by the lever 62a. At this time, the drive switch of the pump 30 is turned off. Thus, the filtered ground water filtered by the filtering device 40 can flow into the drain pipe 44 from the dewatering pipe 61 without passing through the pump 30.

  Furthermore, in the above-described embodiment, the drive switch of the lens grinding apparatus 10 and the drive switch of the pump 30 are ON / OFF controlled in conjunction with each other. The drive switch of the pump 30 may be individually controlled.

  In this case, regardless of the ON / OFF state of the drive switch of the lens grinding apparatus 10, the drive switch of the pump 30 is turned ON, and the filtered grinding water filtered by the filtration device 40 circulates in the grinding water tank 20. Is desirable.
