By setting the spring four, the falling speed of the filter plate can be accelerated, and the filter hole can allow the grinding liquid entering the aggregate trough to re-enter the interior of the bottom plate through the filter hole.

[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention utilizes the relative rotation between the filter cartridge 1 and the filter cartridge 2 to make the sieve holes on the filter cartridge 1 partially overlap with the sieve holes on the filter cartridge 2. During the resetting process, the area of ​​the overlapping part will increase, thereby allowing the particles stuck in the sieve holes to fall off. Specifically, the filter cartridge 1 will drive the rotating plate 1 to rotate together during the rotation process. The rotating plate will first stretch the spring 2 and finally contact the fixed plate. During the process of the rotating plate stretching the spring 2, the elastic force of the spring 2 alone cannot completely pull the filter cartridge 2. When the rotating plate contacts the fixed plate, the filter cartridge 1 will drive the filter cartridge 2 to rotate together. At this time, the sieve holes on the filter cartridge 1 and the sieve holes on the filter cartridge 2 are The holes will partially overlap, and the grinding liquid can only pass through the overlapping part of the sieve holes, and when the filter cartridge stops rotating, the block will be separated from the connecting frame. At this time, the filter cartridge can rotate freely, so the filter cartridge will be pulled to reset by the spring. In the process of resetting, the overlapping area of ​​the sieve holes on the filter cartridge one and the sieve holes on the filter cartridge two will increase, so that the particles stuck in the sieve holes that overlap with the filter cartridge two before the filter cartridge one is reset can fall off. This design can make the particles that block the sieve holes fall off when the filter cartridge stops rotating, thereby preventing the sieve holes of the filter cartridge one from being blocked after a long period of work, which will slow down the speed at which the liquid passes through the filter, thereby reducing the filtration efficiency.

[0017] (2) The present invention starts the motor, which drives the gear rod 1 to rotate. The gear rod 1 drives the conical block and the grinding plate to rotate through the gear rod 2, thereby grinding and polishing the screen cover. The sprayed grinding liquid flows down from the four sides of the grinding plate and falls on the guide plate 1. The grinding liquid falls on the conical block through the guide plate 1. The grinding liquid falling on the conical block is thrown outward to the inner wall of the filter cartridge 1 due to the action of centrifugal force. During the rotation of the gear rod 2, the block is subjected to an outward force due to the action of centrifugal force, which stretches the spring 1 and rotates outward. At this time, the block is stuck in the inside of the connecting frame, so that the gear rod 2 drives the connecting frame to rotate. The connecting frame drives the filter cartridge 1 to rotate. During the rotation of the filter cartridge 1, the grinding liquid falling on the inner wall of the filter cartridge 1 is centrifugally filtered. This design can perform preliminary centrifugal filtration on the grinding liquid and reduce the working pressure of subsequent filtration. The preliminary filtration can separate larger particles in the grinding liquid from the grinding liquid, effectively remove large particle impurities in the grinding liquid, and prevent them from causing blockage and damage to subsequent equipment, thereby affecting the operating stability and life of the equipment.

[0018] (3) The filter cartridge 1 of the present invention will drive the rotating plate to rotate during the rotation process, and the rotating plate will drive the counterweight block to rotate through the fixed shell. During the rotation process, the counterweight block will pull the pressure plate outward due to the action of centrifugal force, and the pressure plate will compress the spring 3 and press the air in the fixed shell into the interior of the rotating plate through the air guide tube. The air pressed into the interior of the rotating plate will push the sliding plate toward the conical block. The sliding plate will drive the shielding plate to move together with the movement, and then the shielding plate will shield the space between the bottom of the conical block and the inner wall of the filter cartridge 1. This design can shield the space between the filter cartridge 1 and the conical block during the centrifugal filtration process, preventing the grinding liquid from falling directly without being filtered, resulting in incomplete filtration and affecting the purity of the grinding liquid after filtration.

[0019] (4) In the centrifugal filtration process of the present invention, the filtered grinding liquid will be thrown onto the inner wall of the shell and fall onto the guide plate 2 along the inner wall of the shell. The grinding liquid falling on the guide plate 2 will flow along the guide plate 2 toward the center of the shell and finally fall onto the filter plate. The grinding liquid falling on the filter plate will be filtered by the filter plate during the flow along the filter plate. The filtered grinding liquid will fall to the bottom of the inner wall of the bottom plate and can be discharged through the discharge port 2 opened at the bottom of the bottom plate. During the rotation of the filter cartridge 1, the fixed rotating ring will be driven to rotate through the rotating plate. During the rotation of the fixed rotating ring, the protruding block 1 will be driven to rotate together. When the protruding block rotates to When the bottom of the fixed rod is reached, it will lift the fixed rod upward, and the fixed rod will drive the filter plate to move upward together. When the raised block is separated from the fixed rod, the filter plate will fall down again. This is repeated, which can have an effect similar to vibration, so that the filter plate can vibrate the filtered particles outward to the inside of the aggregate trough, and the grinding liquid entering the aggregate trough can re-enter the inside of the bottom plate through the filter holes. This design can prevent the filter plate from being blocked by vibrating the filter plate, and can perform secondary filtration on the grinding liquid, which can further remove tiny particles and fine impurities in the grinding liquid, which helps to improve the purity and stability of the grinding liquid and ensure that the quality of the products produced meets the requirements.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For example, see Figure 1 - Figure 5 The present invention is a screen cover polishing liquid recycling device, comprising a centrifugal assembly 1, the centrifugal assembly 1 comprising a housing 101, a bottom plate 102 is fixedly connected to the bottom of the housing 101, a collecting trough 103 is fixedly connected to the outer surface of the bottom plate 102, and further comprising:

[0035] The re-filter assembly 4 comprises a guide cavity 401 rotatably connected to the bottom of the rotating plate 301 , a baffle shell 402 is fixedly connected to the inner wall of the guide cavity 401 , and a guide plate 2 403 is fixedly connected to the inner wall of the outer shell 101 .

[0036] A motor 104 is fixedly connected to the right side of the collecting trough 103, and a gear rod 105 is fixedly connected to the output end of the motor 104. The top of the gear rod 105 is meshedly connected to the gear rod 2 106, and the top of the gear rod 2 106 is fixedly connected to a grinding plate 107. The inner wall of the shell 101 is fixedly connected to a guide plate 108. When the motor 104 is started, the motor 104 will drive the gear rod 105 to rotate, and the gear rod 105 will drive the conical block 112 and the grinding plate 107 to rotate through the gear rod 2 106, thereby grinding and polishing the screen cover, and the sprayed grinding liquid will flow down from the four sides of the grinding plate 107 and fall on the guide plate 108, and the grinding liquid will fall on the conical block 112 through the guide plate 108.

[0037] The inner wall of the gear rod 106 is rotatably connected with a block 109, and the outer surface of the gear rod 106 is fixedly connected with a connecting frame 111. The block 109 is fixedly connected with a spring 110 on the side away from the connecting frame 111. The spring 110 is fixedly connected to the inner wall of the gear rod 106 at the end away from the block 109. The outer surface of the gear rod 106 is fixedly connected with a cone block 112, and the outer surface of the connecting frame 111 is fixedly connected with a filter cartridge 113. The bottom of the bottom plate 102 is respectively provided with a discharge port 1 and a discharge port 2, and the bottom of the collecting trough 103 is provided with a discharge port 3. The grinding liquid falling on the cone block 112 will be thrown outward to the inner wall of the filter cartridge 113 due to the centrifugal force, and the gear rod 106 is rotating. During the process, due to the action of centrifugal force, the block 109 is subjected to an outward force, which will stretch the spring 110 and rotate outward. At this time, the block 109 will be stuck in the inside of the connecting frame 111, so that the gear rod 106 drives the connecting frame 111 to rotate, and the connecting frame 111 drives the filter cartridge 113 to rotate. During the rotation process, the filter cartridge 113 will centrifugally filter the grinding liquid falling on the inner wall of the filter cartridge 113. This design can perform preliminary centrifugal filtration on the grinding liquid and reduce the working pressure of subsequent filtration. The preliminary filtration can separate larger particles in the grinding liquid from the grinding liquid, effectively remove large particle impurities in the grinding liquid, and prevent them from causing blockage and damage to subsequent equipment, affecting the operating stability and life of the equipment.

[0038] For example 2, please refer to Figure 6 - Figure 8The present invention is a recycling device for screen cover polishing liquid. On the basis of Example 1, the inner wall of the second filter cartridge 201 is rotatably connected to the outer surface of the first filter cartridge 113, the top of the fixed ring 202 is fixedly connected to the bottom of the guide plate 108, and the outer surface of the first filter cartridge 113 is fixedly connected with a rotating plate 205. A second spring 204 is arranged inside the fixed ring 202. The second spring 204 is fixedly connected to the rotating plate 205 at one end away from the fixed plate 203. The second spring 204 is fixedly connected to the fixed plate 203 at one end away from the rotating plate 205. The first filter cartridge 113 will drive the rotating plate 205 to rotate during the rotation process. The rotating plate 205 will first stretch the second spring 204 and finally contact with the fixed plate 203. In the process of the rotating plate 205 stretching the second spring 204, the second filter cartridge 201 cannot be completely pulled by the elastic force of the second spring 204 alone, and when the rotating plate 205 is in contact with the fixed plate 203, the second filter cartridge 201 will be completely pulled by the elastic force of the second spring 204. When the plate 203 contacts, the filter cartridge 113 will drive the filter cartridge 201 to rotate together. At this time, the sieve holes on the filter cartridge 113 and the sieve holes on the filter cartridge 201 will partially overlap, and the grinding liquid can only pass through the overlapping part of the sieve holes. When the filter cartridge 113 stops rotating, the block 109 will be separated from the connecting frame 111. At this time, the filter cartridge 113 can rotate freely, so the filter cartridge 113 will be pulled to reset by the spring 204. During the resetting process, the area of ​​the overlapping part of the sieve holes on the filter cartridge 113 and the sieve holes on the filter cartridge 201 will increase, so that the particles stuck in the sieve holes that overlap with the filter cartridge 2 201 before the filter cartridge 113 is reset can fall off. This design can make the particles that block the sieve holes fall off when the filter cartridge 113 stops rotating, thereby preventing the sieve holes of the filter cartridge 113 from being blocked after a long period of work, resulting in a slowdown in the speed at which the liquid passes through the filter screen, thereby reducing the filtration efficiency.

[0039] The top of the rotating plate 301 is fixedly connected to the bottom of the filter cartridge 113, and the counterweight block 303 is fixedly connected to a pressure plate 304 at one end close to the gear rod 2 106. The outer surface of the pressure plate 304 is slidingly connected to the inner wall of the fixed shell 302, and the pressure plate 304 is fixedly connected to a spring 305 on the side away from the gear rod 2 106. The filter cartridge 113 will drive the rotating plate 301 to rotate during the rotation process, and the rotating plate 301 will drive the counterweight block 303 to rotate through the fixed shell 302. During the rotation process, the counterweight block 303 will pull the pressure plate 304 outward due to the action of centrifugal force.

[0040] The spring three 305 is fixedly connected to the inner wall of the fixed shell 302 at one end away from the pressure plate 304, and the fixed shell 302 is fixedly connected to an air guide tube 306 at one side away from the gear rod two 106. The air guide tube 306 is fixedly connected to the bottom of the rotating plate 301 at one end away from the fixed shell 302. The inner wall of the rotating plate 301 is slidably connected to a sliding plate 307. The sliding plate 307 is fixedly connected to a shielding plate 308 on the side close to the gear rod two 106. The outer surface of the shielding plate 308 is slidably connected to the inner wall of the rotating plate 301. The pressure plate 304 will compress the spring three 305 and open the air in the fixed shell 302. The air is pressed into the interior of the rotating plate 301 through the air guide tube 306. The air pressed into the interior of the rotating plate 301 will push the sliding plate 307 towards the direction close to the conical block 112. The sliding plate 307 will drive the shielding plate 308 to move while moving, and then the shielding plate 308 will shield the space between the bottom of the conical block 112 and the inner wall of the filter cartridge 113. This design can shield the space between the filter cartridge 113 and the conical block 112 during the centrifugal filtration process to prevent the grinding liquid from falling directly without being filtered, resulting in incomplete filtration and affecting the purity of the grinding liquid after filtration.

[0041] A fixed swivel 404 is fixedly connected to the bottom of the rotating plate 301, a raised block 405 is fixedly connected to the inner wall of the fixed swivel 404, a filter plate 407 is slidably connected to the outer surface of the guide cavity 401, and a fixed rod 406 is fixedly connected to the top of the filter plate 407. During the centrifugal filtration process, the filtered grinding liquid will be thrown onto the inner wall of the outer shell 101, and will fall onto the guide plate 2 403 along the inner wall of the outer shell 101. The grinding liquid falling on the guide plate 2 403 will flow along the guide plate 2 403 to the center of the outer shell 101, and finally fall on the filter plate 407. The grinding liquid falling on the filter plate 407 will be filtered by the filter plate 407 during the process of flowing along the filter plate 407, and the filtered grinding liquid will fall on the bottom of the inner wall of the bottom plate 102, and can be discharged through the discharge port 2 opened at the bottom of the bottom plate 102.

[0042] The bottom of the filter plate 407 contacts the limit ring 408, the inner wall of the limit ring 408 is fixedly connected to the outer surface of the guide cavity 401, the bottom of the filter plate 407 is fixedly connected with a spring four 409, the bottom of the spring four 409 is fixedly connected to the bottom of the inner wall of the bottom plate 102, the outer surface of the bottom plate 102 is provided with a filter hole 410, the filter cartridge 113 will drive the fixed rotating ring 404 to rotate through the rotating plate 301 during the rotation process, and the fixed rotating ring 404 will drive the raised block 405 to rotate together during the rotation process, and when the raised block 405 rotates to the bottom of the fixed rod 406, it will lift the fixed rod 406 upward, and the fixed rod 406 will drive the filter The plate 407 moves upward together, and when the protruding block 405 is separated from the fixing rod 406, the filter plate 407 will fall down again. This repeated movement can have an effect similar to vibration, so that the filter plate 407 vibrates the filtered particles outward to the inside of the aggregate trough 103, and the grinding liquid entering the aggregate trough 103 can re-enter the inside of the bottom plate 102 through the filter hole 410. This design can prevent the filter plate 407 from being blocked by vibration, and can perform secondary filtration on the grinding liquid, which can further remove tiny particles and fine impurities in the grinding liquid, which helps to improve the purity and stability of the grinding liquid and ensure that the quality of the products produced meets the requirements.

[0043] A specific application of this embodiment is: when using the device, first install the device at a suitable position. When the screen cover plate is to be polished, the screen cover plate needs to be pressed on the top of the grinding plate 107, and then the grinding liquid is continuously sprayed on the top of the grinding plate 107. At the same time, the motor 104 is started, and the motor 104 drives the gear rod 105 to rotate. The gear rod 105 drives the conical block 112 and the grinding plate 107 to rotate through the gear rod 2 106, and then the screen cover plate is ground and polished. The sprayed grinding liquid flows down from the four sides of the grinding plate 107 and falls on the guide plate 108. The grinding liquid falls on the conical block 112 through the guide plate 108. The grinding liquid falling on the conical block 112 will be thrown outward to the filter cartridge 1 due to the action of centrifugal force. 113, and during the rotation of the gear rod 106, due to the effect of centrifugal force, the block 109 is subjected to an outward force, which will stretch the spring 110 and rotate outward. At this time, the block 109 will be stuck in the inside of the connecting frame 111, so that the gear rod 106 drives the connecting frame 111 to rotate, and the connecting frame 111 drives the filter cartridge 113 to rotate. During the rotation of the filter cartridge 113, the grinding liquid falling on the inner wall of the filter cartridge 113 will be centrifugally filtered. This design can perform preliminary centrifugal filtration on the grinding liquid and reduce the working pressure of subsequent filtration. The preliminary filtration can separate larger particles in the grinding liquid from the grinding liquid, effectively remove large particle impurities in the grinding liquid, and prevent them from causing blockage and damage to subsequent equipment, affecting the stable operation of the equipment. In order to improve the quality and service life of the filter cartridge 113, the rotating plate 205 will be driven to rotate during the rotation process, and the rotating plate 205 will first stretch the spring 204 and finally contact with the fixed plate 203. In the process of the rotating plate 205 stretching the spring 204, the filter cartridge 201 cannot be completely pulled by the elastic force of the spring 204 alone, and when the rotating plate 205 contacts the fixed plate 203, the filter cartridge 113 will drive the filter cartridge 201 to rotate together. At this time, the sieve holes on the filter cartridge 113 and the sieve holes on the filter cartridge 201 will partially overlap, and the grinding liquid can only pass through the overlapping part of the sieve holes, and when the filter cartridge 113 stops rotating, the block 109 will be separated from the connecting frame 111, and the filter cartridge 113 can rotate freely at this time, so the filter cartridge 113 will be pulled by the spring The filter cartridge 1 113 is pulled to reset, and during the reset process, the area of ​​the overlapping part of the sieve holes on the filter cartridge 1 113 and the sieve holes on the filter cartridge 2 201 will increase, so that the particles stuck in the sieve holes that overlap with the filter cartridge 2 201 before the filter cartridge 1 113 is reset can fall off. This design can make the particles blocking the sieve holes fall off when the filter cartridge 1 113 stops rotating, and prevent the sieve holes of the filter cartridge 1 113 from being blocked after a long period of work, resulting in a slowdown in the speed of liquid passing through the filter screen, thereby reducing the filtration efficiency. The filter cartridge 1 113 will drive the rotating plate 301 to rotate during the rotation process, and the rotating plate 301 will drive the counterweight block 303 to rotate through the fixed shell 302. During the rotation process, the counterweight block 303 will pull the pressure plate 304 outward due to the effect of centrifugal force.The pressure plate 304 will compress the spring three 305 and press the air in the fixed shell 302 into the interior of the rotating plate 301 through the air guide tube 306. The air pressed into the interior of the rotating plate 301 will push the sliding plate 307 towards the direction close to the conical block 112. The sliding plate 307 will drive the shielding plate 308 to move while moving, and then the shielding plate 308 will shield the space between the bottom of the conical block 112 and the inner wall of the filter cartridge 113. This design can shield the space between the filter cartridge 113 and the conical block 112 during the centrifugal filtration process to prevent the grinding liquid from falling directly without being filtered, resulting in incomplete filtration and affecting the process. The purity of the grinding liquid after filtration, during the centrifugal filtration process, the filtered grinding liquid will be thrown on the inner wall of the shell 101, and will fall on the guide plate 2 403 along the inner wall of the shell 101, and the grinding liquid falling on the guide plate 2 403 will flow along the guide plate 2 403 to the center of the shell 101, and finally fall on the filter plate 407, and the grinding liquid falling on the filter plate 407 will be filtered by the filter plate 407 during the process of flowing along the filter plate 407, and the filtered grinding liquid will fall on the bottom of the inner wall of the bottom plate 102, and can be discharged through the discharge port 2 opened at the bottom of the bottom plate 102. The filter cartridge 1 113 will pass through the rotating plate 30 during the rotation process. 1 drives the fixed swivel 404 to rotate, and the fixed swivel 404 drives the protruding block 405 to rotate during the rotation process. When the protruding block 405 rotates to the bottom of the fixed rod 406, it lifts the fixed rod 406 upward, and the fixed rod 406 drives the filter plate 407 to move upward together. When the protruding block 405 is separated from the fixed rod 406, the filter plate 407 will fall again. This repetition can have a vibration effect, so that the filter plate 407 can vibrate the filtered particles outward to the inside of the collecting tank 103, and the grinding liquid entering the collecting tank 103 can re-enter the inner part of the bottom plate 102 through the filter hole 410. This design can prevent the filter plate 407 from being blocked by vibrating it, and can perform secondary filtration on the grinding liquid, which can further remove tiny particles and fine impurities in the grinding liquid, which helps to improve the purity and stability of the grinding liquid and ensure that the quality of the products produced meets the requirements. After the sweeping is completed, the motor 104 is turned off, and the spring three 305 will drive the counterweight block 303 to reset, and then the shielding plate 308 will reset. At this time, the filtered particles will fall into the guide cavity 401 and can be discharged through the discharge port one opened at the bottom of the bottom plate 102. The particles falling into the collecting trough 103 can be discharged through the discharge port three opened at its bottom.
