[0002] Polyvinylidene fluoride, abbreviated as PVDF, is a highly non-reactive thermoplastic fluoropolymer, which can be used as an engineering plastic for making sealing rings, corrosion-resistant equipment, capacitors, and also used as coatings, insulating materials, and ion exchange membrane materials, etc. The wet powder purification equipment belongs to a device for recycling polyvinylidene fluoride powder. When recycling polyvinylidene fluoride powder, impurities in it need to be filtered out with pure water, which will generate a polyvinylidene fluoride powder mixture mixed with pure water. The polyvinylidene fluoride powder wet powder in the mixture needs to be filtered out before drying operation can be carried out.

[0003] At present, when most of the polyvinylidene fluoride powder wet powder purification equipment on the market is in use, traditional pressure filtration will cause the polyvinylidene fluoride powder wet powder in the mixture to adhere to the inner bottom wall of the pressure filtration device, and it needs to be manually taken out before drying operation.

[0013] Preferably, the number of teeth of the linkage rack can drive the reversing gear to rotate one week.

[0014] Preferably, a method for using the polyvinylidene fluoride powder wet powder purification equipment includes the following steps: S1: Open the control valve in the feed pipe, and inject the mixed liquid of the filtered polyvinylidene fluoride powder mixed with pure water from the feed pipe into the feed bin. The mixed liquid in the feed bin will enter the filter press bin under the action of gravity, and then close the control valve and start the hydraulic telescopic machine. The hydraulic telescopic machine pushes the telescopic pipe downward, and the telescopic pipe pushes the water distribution platform downward. The water distribution platform pushes the ultrafiltration plate to contact the mixed liquid through the driving force of the upper connecting block, the deflection plate and the lower connecting block. Under the action of pressure, the telescopic bag contracts and the pressure inside it pushes the movable flap to flip upward, so that the ultrafiltration plate filters the water in the mixed liquid and moves it to the top of the water distribution platform. When the ultrafiltration plate is docked with the top of the flipping platform, the polyvinylidene fluoride in the mixed liquid The olefin powder and wet material are separated between the ultrafiltration plate and the turning table. At this time, the telescopic tube continues to push the water distribution table downward, so that the upper connecting block pushes the lower connecting block to slide on the top of the ultrafiltration plate through the deflection plate, causing the telescopic bag to shrink. When the air in the telescopic bag is discharged, it will drive the pure water separated between the water distribution table and the ultrafiltration plate to be discharged. When the hydraulic telescopic machine moves downward, it drives the linkage tooth plate to move downward through the connecting plate. The linkage tooth plate drives the turning gear to rotate under the meshing force, and the turning gear drives the rotating ring to rotate. When the rotating ring rotates, it will drive the toggle block to rotate. After the inclined surface of the toggle block abuts against the inclined surface of the push block, the toggle block will cause the push block to shrink into the telescopic groove. At this time, the linkage tooth plate will idle.

[0015] S2: When the hydraulic telescopic machine contracts, it will drive the telescopic tube to move upward, and the telescopic tube will drive the water distribution platform to move upward. The water distribution platform will push the pure water above to move upward and enter the discharge pipe. At the same time, the hydraulic telescopic machine drives the linkage tooth plate to move through the connecting plate. The linkage tooth plate drives the flip gear to rotate under the meshing force. The flip gear makes the back of the toggle block contact the back of the push block through the rotating ring, so that the toggle block drives the flip rod to rotate, and the flip rod drives the flip table to flip, so that the top of the flip table moves to the original bottom position, so that the polyvinylidene fluoride The powder and wet material detach from the bottom of the turning table under the action of gravity and gravitation and fall into the discharge bin. The turning rod will drive the positioning plate to rotate when it rotates. When the turning table is turned over, the positioning plate will be inserted by the plug-in block and limit the turning rod. The booster pump is turned on. Pure water enters the input pipe after pressurization. The pure water enters the impeller bin through the input pipe and drives the impeller to rotate. The impeller drives the auger to rotate. The auger pushes the polyvinylidene fluoride powder and wet material from the discharge bin into the collection bin. After driving the impeller to rotate, the pure water enters the water storage bin through the output pipe.

[0016] S3: At this time, start the water pump. The water pump can introduce the pure water in the water storage bin into the water delivery pipe through the connecting pipe, enter the telescopic pipe through the hose, and finally enter the rotating bin. The pure water in the rotating bin enters the cleaning pipe under the action of pressure. Since the cleaning pipe with the inclined nozzle can drive the rotating bin to rotate at the end of the telescopic pipe under the impact force of the water flow when shooting out pure water to clean the ultrafiltration plate, the blocked polyvinylidene fluoride powder wet material in the ultrafiltration plate can be blown out more efficiently. At the same time, the telescopic bladder is reset. After the cleaning is completed, start the hydraulic telescopic machine again to make the telescopic pipe complete the telescopic function again. When the turning platform is reset, the polyvinylidene fluoride powder wet material attached to it can enter the discharge bin again, and the pure water used for cleaning is discharged.

[0017] The present invention provides a polyvinylidene fluoride powder wet purification device and a use method. Compared with the prior art, it has the following beneficial effects: (1) Through the mutual cooperation of the telescopic linkage component, the turning component and the pressure filtration component, the hydraulic telescopic machine drives the turning gear to rotate through the linkage tooth plate, and the polyvinylidene fluoride powder wet material after being pressure filtered by the water dividing table and the ultrafiltration plate can be turned into the discharge bin, without the need for staff to open the device to take out the polyvinylidene fluoride powder wet material, avoiding the internal pollution of the device.

[0018] (2) Through the mutual cooperation of the pressure filtration component, the cleaning component and the output component, by the impact of the filtered pure water and the pressure impact of the telescopic bladder, the polyvinylidene fluoride powder blocked in the ultrafiltration plate can be cleaned out, avoiding the blockage of the ultrafiltration plate and affecting the normal operation of pressure filtration.

[0019] (3) Through the mutual cooperation of the cleaning component, the output component and the drainage component, by pressurizing the filtered pure water to impact the impeller, the auger is driven to rotate to export the polyvinylidene fluoride powder wet material from the device, bringing convenience to the collection work of the staff.

[0032] A method for using a polyvinylidene fluoride powder wet powder purification device comprises the following steps: S1: Open the control valve in the feed pipe 107, and inject the mixed liquid of the polyvinylidene fluoride powder mixed with pure water after filtration from the feed pipe 107 into the feed bin 106. The mixed liquid in the feed bin 106 will enter the filter press bin 103 under the action of gravity, and then close the control valve and start the hydraulic telescopic machine 201. The hydraulic telescopic machine 201 pushes the telescopic tube 401 to move downward, and the telescopic tube 401 pushes the water diversion platform 402 to move downward. The water diversion platform 402 pushes the ultrafiltration plate 405 to contact the mixed liquid through the driving force of the upper connecting block 406, the deflection plate 407 and the lower connecting block 408. Under the action of pressure, the contraction of the telescopic bag 404 and the pressure inside it will push the movable flap 403 to flip upward, so that the ultrafiltration plate 405 filters out the water in the mixed liquid and moves it to the top of the water diversion platform 402. When the ultrafiltration plate 405 is docked with the top of the flipping platform 307, the wet polyvinylidene fluoride powder in the mixed liquid is separated. 406 pushes the lower connecting block 408 to slide on the top of the ultrafiltration plate 405 through the deflection plate 407, so that the telescopic bag 404 shrinks. When the air in the telescopic bag 404 is discharged, the pure water separated between the water diversion platform 402 and the ultrafiltration plate 405 is discharged. When the hydraulic telescopic machine 201 moves downward, it drives the linkage tooth plate 203 to move downward through the connecting plate 202. The linkage tooth plate 203 drives the flipping gear 301 to rotate under the meshing force. The flipping gear 301 drives the rotating ring 302 to rotate. When the rotating ring 302 rotates, it drives the toggle block 303 to rotate. After the inclined surface of the toggle block 303 abuts against the inclined surface of the push block 304, the toggle block 303 causes the push block 304 to shrink into the telescopic groove. At this time, the linkage tooth plate 203 rotates idly.

[0033] S2: When the hydraulic telescopic machine 201 contracts, it will drive the telescopic tube 401 to move upward, and the telescopic tube 401 will drive the water distribution platform 402 to move upward. The water distribution platform 402 pushes the pure water above to move upward and enter the discharge pipe 703. At the same time, the hydraulic telescopic machine 201 drives the linkage tooth plate 203 to move through the connecting plate 202. The linkage tooth plate 203 drives the flip gear 301 to rotate under the meshing force. The flip gear 301 makes the back of the toggle block 303 contact the back of the push block 304 through the rotating ring 302, so that the toggle block 303 drives the flip rod 306 to rotate, and the flip rod 306 drives the flip table 307 to flip, so that the top of the flip table 307 moves to the original bottom position, so that the polyvinylidene fluoride powder The wet material detaches from the bottom of the turning table 307 under the action of gravity and gravitation and falls into the discharge bin 104. The turning rod 306 drives the positioning plate 309 to rotate when it rotates. When the turning table 307 is turned over, the positioning plate 309 is inserted by the plug-in block 310 and limits the turning rod 306. The booster pump 702 is turned on. Pure water enters the input pipe 601 after being pressurized. The pure water enters the impeller bin 602 through the input pipe 601 and drives the impeller 604 to rotate. The impeller 604 drives the auger 605 to rotate. The auger 605 pushes the wet polyvinylidene fluoride powder from the discharge bin 104 into the collection bin 102. After driving the impeller 604 to rotate, the pure water passes through the output pipe 603 and enters the water storage bin 504.

[0034] S3: At this time, the water pump 502 is started. The water pump 502 can guide the pure water in the water storage tank 504 into the water delivery pipe 501 through the connecting pipe 503, and enter the telescopic tube 401 through the hose, and finally enter the rotating tank 410. The pure water in the rotating tank 410 enters the cleaning pipe 411 under the action of pressure. Due to the inclined nozzle, the cleaning pipe 411 can drive the rotating tank 410 to rotate at the end of the telescopic tube 401 under the impact force of the water flow when ejecting pure water to clean the ultrafiltration plate 405, so as to more efficiently blow out the blocked polyvinylidene fluoride powder wet material in the ultrafiltration plate 405, and reset the telescopic bag 404 at the same time. After cleaning, the hydraulic telescopic machine 201 is started again to make the telescopic tube 401 complete the telescopic effect again, so that the turning table 307 is reset, and the polyvinylidene fluoride powder wet material attached thereto can enter the discharge bin 104 again, and the pure water for cleaning is discharged.
