Description
A filter plate clump cleaning device for a filter press Technical Field
[0001] This invention relates to the field of cleaning device technology, and more specifically to a device for cleaning filter plates that stick to filter presses. Background Technology
[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to the liquid to be filtered, causing the liquid to seep out. It is a commonly used solid-liquid separation device. In the production of positive electrode materials for new energy lithium batteries, filter presses are used to separate solid particles from cobalt sulfate mother liquor to reduce solid loss during processing, thereby improving resource utilization.
[0003] The filter cloth mounted on the outside of the filter plates in a filter press needs to be disassembled and cleaned periodically, a tedious process. Therefore, many companies choose to clean the surface of the filtration equipment directly with a brush. However, this method is ineffective at cleaning the filter cloth, only removing surface filter cake residue, leaving the filter residue within the pores uncleaned, leading to clogging or hardening over time. Furthermore, most filter plates now have multiple protrusions; directly cleaning the filter cloth surface will squeeze it against these protrusions, easily causing damage during the scraping process. On the other hand, directly washing and discharging solid residues such as cobalt carbonate from the filter cloth also results in resource waste. Therefore, this invention aims to provide a cleaning device that is clean, efficient, and can automatically collect solid residues, reducing filter cloth wear. Summary of the Invention
[0004] Therefore, the present invention provides a filter plate sticking cleaning device for a filter press to solve the above-mentioned defects in the prior art.
[0005] A filter plate clump cleaning device for a filter press includes a guide rail frame, a movable slide mounted horizontally on the guide rail frame, a cleaning mechanism that can be lifted and lowered on the movable slide frame via a lifting mechanism, and a recycling device fixedly mounted on the movable slide frame below the cleaning mechanism.
[0006] The cleaning mechanism includes a cleaning seat and mounting brackets symmetrically installed on both sides of the cleaning seat. A spray assembly and a U-shaped scraper assembly are installed vertically on the inner side of the mounting bracket. The U-shaped scraper assembly includes a horizontal scraper and lateral pressure blocks installed on both sides of the horizontal scraper. A swing cleaning assembly is installed on the mounting bracket above the horizontal scraper. The swing cleaning assembly includes a swing arm whose outer end rotates around a swing axis. An air guide cylinder is provided at the inner end of the swing arm. A brush block is slidably installed inside the air guide cylinder. The brush block is driven by a power mechanism to slide along the air guide cylinder on the swinging swing arm, thereby creating a brief negative pressure inside the air guide cylinder to adsorb the filter cloth onto the inner surface of the U-shaped scraper assembly.
[0007] Preferably, the power mechanism includes a bearing seat mounted on the lateral pressure block, a rotating plate rotatably mounted at both ends of the bearing seat, and a guide shaft groove formed on the rotating plate. The first rotating rod is limited at both ends and mounted in the guide shaft groove on the corresponding side. The first rotating rod is rotatably mounted through the brush block. A telescopic cylinder connected to the end of the first rotating rod is mounted on the rotating plate. The first rotating rod is arranged parallel to the rotation axis of the rotating plate. The telescopic cylinder is used to adjust the distance between the first rotating rod and the rotation axis of the rotating plate.
[0008] Preferably, the bottom of the lateral pressure block has a limiting groove with downward and outward openings. A transverse brush plate is slidably installed inside the limiting groove. The power mechanism includes a rotating shaft driven by a first motor. A first cam is installed on the rotating shaft. A guide cylinder is installed on the back of the lateral pressure block. A pressure block is installed at the bottom of the guide cylinder via a first spring. A first wedge block is connected to the outside of the pressure block. A second wedge block that cooperates with the first wedge block is installed on the transverse brush plate. When the first wedge block presses against the second wedge block, the transverse brush plate connected to the second wedge block moves outward from the limiting groove.
[0009] Preferably, the recycling device includes a water tank installed below the movable slide, a filter plate is hinged to one end of the water tank, the bottom of the filter plate is connected to the water tank by a return spring, a second rotating rod is installed below one side of the filter plate, a second cam is installed on the second rotating rod that can act on the bottom of the filter plate, a gear is installed at one end of the second rotating rod, a rack that meshes with the gear is vertically installed on the mounting bracket, a collection frame is installed below the inclined filter plate, the water tank is connected to the spray assembly through a water pipe, and a water pump is installed on the water pipe.
[0010] Preferably, the spray assembly includes a spray pipe mounted on a mounting bracket, the spray pipe having a plurality of inwardly facing spray heads, and the spray pipe being connected to a water supply end.
[0011] Preferably, the lifting mechanism includes two lead screws that are vertically rotatably mounted on the movable slide, with one end of the two lead screws connected by a pulley assembly. One of the lead screws is driven to rotate by a second motor. The movable slide has a vertical guide groove, and the cleaning seat is slidably positioned in the vertical guide groove. The cleaning seat is fitted onto the lead screw by a lead screw nut.
[0012] Preferably, when the transverse brush plate moves outward, the brush block moves towards the inner end of the air guide cylinder.
[0013] The present invention has the following advantages:
[0014] (1) The present invention can achieve different cleaning of attachments of different block sizes. First, the U-shaped scraping component is used to scrape off the larger protruding attachments on the surface of the filter cloth. Then, the swing cleaning component is used to alternate between "adsorption mode" and "brushing mode", so that the brush block can clean the small pieces on the surface of the filter cloth that are lifted off the filter plate and the adsorbed attachments in the pores during the swinging process, which has a strong cleaning force on the filter cloth.
[0015] (2) In the "adsorption mode" of this invention, the water-absorbing filter cloth will be adsorbed onto the inner end of the air guide cylinder. On the one hand, this facilitates gently lifting the filter cloth from the surface of the filter plate, avoiding the filter cloth always sticking to the surface of the filter plate during the cleaning process, which would cause wear during cleaning; on the other hand, the filter cloth can stick to the inner side of the U-shaped scraper assembly, providing adhesion for the vertical scraping of the horizontal scraper;
[0016] (3) In the "brushing mode" of the present invention, the brush will swing and brush the mud adsorbed from the filter cloth, and simultaneously drive the horizontal brush plate to scrape the mud pressed by the lower part of the side pressure block along the outer end of the side pressure block, which can avoid creating a blind spot for cleaning and make the filter cloth under the side pressure block clean. In addition, the above can avoid the sinking of the middle part of the filter cloth caused by the brushing of the brush block. During the process of the horizontal brush plate being pulled out horizontally from the side pressure block, the instantaneous negative pressure formed at the lower end of the side pressure block, plus the friction between the horizontal brush plate and the two ends of the filter cloth, can instantly straighten the sunken filter cloth horizontally. It can also complete the shaking of the filter cloth during the tightening process, improving the cleaning effect.
[0017] (4) Through the cooperation between devices, the present invention can automatically collect cobalt carbonate and recycle wastewater, thus improving the overall efficiency of cleaning the filter cloth without disassembling it. Attached Figure Description

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0034] As shown in Figures 1 to 10, the present invention provides a filter plate sticking cleaning device for a filter press, including a guide rail frame 1, a movable slide 2 horizontally slidably mounted on the guide rail frame 1, a cleaning mechanism 4 that can be lifted and lowered on the movable slide 2 via a lifting mechanism 3, and a recycling device 5 fixedly mounted on the movable slide 2 and located below the cleaning mechanism 4.
[0035] The cleaning mechanism 4 includes a cleaning seat 401 and mounting brackets 402 symmetrically installed on both sides of the cleaning seat 401. The lifting mechanism 3 includes two lead screws 302 vertically rotatably mounted on the movable slide 2. One end of the two lead screws 302 is connected by a pulley assembly 303. One of the lead screws 302 is driven to rotate by a second motor 304. The movable slide 2 has a vertical guide groove. The cleaning seat 401 is slidably positioned in the vertical guide groove and is fitted onto the lead screw 302 by a lead screw nut.
[0036] The second motor 304 drives the two lead screws 302 to rotate synchronously, thereby causing the cleaning seat 401 mounted on the lead screws 302 to rise and fall vertically under the guidance of the vertical guide groove.
[0037] The spray assembly 403 and the U-shaped scraper assembly are installed vertically and vertically on the inner side of the mounting bracket 402.
[0038] The spray assembly 403 includes a spray pipe mounted on the mounting bracket 402, and the spray pipe is provided with a plurality of inwardly facing spray heads. The spray pipe is connected to the water supply end.
[0039] The U-shaped scraping assembly includes a horizontal scraper 422 and lateral pressure blocks 423 installed on both sides of the horizontal scraper 422. A swing cleaning assembly 404 is installed on the mounting bracket 402 above the horizontal scraper 422. The swing cleaning assembly 404 includes a swing arm 405 whose outer end rotates around a swing shaft 421. An air guide cylinder 406 is provided at the inner end of the swing arm 405. A brush block 407 is slidably installed inside the air guide cylinder 406.
[0040] The brush block 407 is driven by a power mechanism to slide along the air guide cylinder 406 on the swinging swing arm 405, thereby creating a brief negative pressure inside the air guide cylinder 406 that adsorbs the filter cloth 10 onto the inner surface of the U-shaped scraper assembly. Specifically:
[0041] The power mechanism includes a bearing seat 417 mounted on the lateral pressure block 423, a rotating plate 419 rotatably mounted at both ends of the bearing seat 417, and a guide shaft groove 418 formed on the rotating plate 419. The first rotating rod 420 is limited at both ends and mounted in the guide shaft groove 418 on the corresponding side. The first rotating rod 420 is rotatably mounted through the brush block 407. A telescopic cylinder 410 connected to the end of the first rotating rod 420 is mounted on the rotating plate 419. The first rotating rod 420 is arranged parallel to the axis of rotation of the rotating plate 419. The telescopic cylinder 410 is used to adjust the distance between the first rotating rod 420 and the axis of rotation of the rotating plate 419.
[0042] The bottom of the lateral pressure block 423 has a limiting groove that opens downwards and outwards. A transverse brush plate 408 is slidably installed inside the limiting groove. When the transverse brush plate 408 moves outwards, the brush block 407 moves towards the inner end of the air guide cylinder 406. Specifically:
[0043] The power mechanism includes a rotating shaft driven to rotate by a first motor (not shown in the figure), and the rotating shaft of the first motor synchronously drives the rotating plate 419 to rotate.
[0044] A first cam 411 is mounted on the rotating shaft. A guide cylinder 412 is mounted on the back of the lateral pressure block 423. A pressure block 414 is mounted on the bottom of the guide cylinder 412 via a first spring 413. A first wedge block 415 is connected to the outside of the pressure block 414. A second wedge block 416 that cooperates with the first wedge block 415 is mounted on the transverse brush plate 408. When the first wedge block 415 presses the second wedge block 416, the transverse brush plate 408 connected to the second wedge block 416 moves toward the outside of the limiting groove.
[0045] The recycling device 5 includes a water tank 501 installed below the movable slide 2. A filter plate 502 is hinged to one end of the water tank 501. The bottom of the filter plate 502 is connected to the water tank 501 by a return spring (not shown in the figure). A second rotating rod 507 is installed below one side of the filter plate 502. A second cam 508 that can act on the bottom of the filter plate 502 is installed on the second rotating rod 507. A gear 506 is installed at one end of the second rotating rod 507. A rack 505 that meshes with the gear 506 is vertically installed on the mounting bracket 402. A collection frame 509 is installed below the inclined filter plate 502. The water tank 501 is connected to the spray assembly 403 through a water pipe 504. A water pump 503 is installed on the water pipe 504.
[0046] The working principle of the device of this invention is as follows:
[0047] I. Adjusting the position:
[0048] The filter plate 20 to be cleaned is moved to a suitable position by the filter plate traction trolley, so that both sides of the filter cloth 30 of the filter plate 20 to be cleaned have sufficient space to move.
[0049] Then, the drive carriage 2 moves along the guide rail 1, so that the two mounting brackets 402 of the cleaning mechanism 4 are symmetrically distributed on the outer sides of the filter cloth 10 on both sides of the filter plate 20 to be cleaned. The second motor 304 drives the mounting bracket 402 on the cleaning seat 401 to descend, and the swing cleaning component 404 mounted on it performs up-and-down reciprocating cleaning of the filter cloth 10. After cleaning is completed, the mounting bracket 402 rises to clean the filter cloth on the outer side of the adjacent filter plate 20.
[0050] 2. Clean the filter cloth fitted on the outside of the filter plate:
[0051] The lifting mechanism 3 drives the mounting bracket 402 to descend along both sides of the filter plate 20. The spray assembly 403 sprays water onto the surface of the filter cloth. On the one hand, some of the residue adhering to the surface of the filter cloth 10 will fall into the water tank 501 below due to the increased gravity after absorbing water. On the other hand, the pores between the filter cloth 10 after absorbing water are filled with water, making it easier for the filter cloth 10 to be absorbed from one side later.
[0052] The cleaning intensity is adjusted according to the state of the residue adhering to the filter cloth surface. When the residue becomes increasingly viscous and difficult to remove, the cleaning intensity is increased, i.e., the oscillation amplitude of the brush block 407 and the force acting on the filter cloth surface (the pressure provided by the brush block 407 towards the filter cloth side) are increased. Specifically:
[0053] The first rotating rod 420 is driven by the telescopic cylinder 410 to slide along the guide shaft groove 418 at both ends. The distance between the axis of the first rotating rod 420 and the rotating shaft of the first motor is adjusted. When the distance between the two is greater, the brush block 407 slides along the air guide cylinder 406 with a greater amplitude, and the swing amplitude of the brush block 407 is also greater.
[0054] During operation, the drive mounting bracket 402 descends along the surface of the filter cloth, and the horizontal scraper 422 mounted on it scrapes away larger protruding adhering substances from the surface of the filter cloth 10. The first motor drives the rotating plate 419 to rotate, causing the first rotating rod 420 mounted between the rotating plates 419 to rotate around the rotating shaft. Rotating the first rotating rod 420, which is fitted inside the brush block 407, drives the swing arm 405 to swing up and down slightly around the swing shaft 421. The brush block 407, slidably mounted on the swing arm 405, cleans small areas on the surface of the filter cloth 10 and adhering substances in the pores during the swinging process.
[0055] During the process, the brush block 407 will slide along the air guide cylinder 406, forming two alternating modes: "adsorption mode" and "brushing mode". Specifically:
[0056] When the brush block 407 moves outward along the air guide cylinder 406, a negative pressure is formed inside the air guide cylinder 406, which is in "adsorption mode". The water-absorbing filter cloth 10 will be adsorbed on the inner end of the air guide cylinder 406.
[0057] On the one hand, this facilitates the gentle lifting of the filter cloth 10 from the surface of the filter plate 20, preventing the filter cloth 10 from always sticking to the surface of the filter plate 20 during the cleaning process, thus avoiding wear during cleaning. In addition, the filter cloth 10 can adhere to the inside of the U-shaped scraper assembly, providing adhesion for the vertical scraping of the horizontal scraper 422. It should be noted that there is a gap between the U-shaped scraper assembly and the surface of the unadsorbed filter cloth 10. On the other hand, the above conditions also facilitate the adsorption of mud that is difficult to clean from the filter cloth and its removal by the brush block 407, thereby improving the cleaning effect on the filter residue in the pores of the filter cloth 10.
[0058] When the brush block 407 moves inward along the air guide cylinder 406, the inner end of the brush block 407 in the air guide cylinder 406 extends out and is in "brushing mode".
[0059] In this mode, the brush will oscillate and scrub the mud adsorbed from the filter cloth 10.
[0060] Simultaneously, the shaft of the first motor 409 drives the first cam 411 to rotate, intermittently pressing against the surface of the pressure block 414. The first wedge block 415 connected to the pressure block 414 presses against the surface of the second wedge block 416, thereby causing the transverse brush plate 408 connected to the second wedge block 416 to scrape out the mud pressed at the lower end of the side pressure block 423 along the outer end of the side pressure block 423, avoiding blind spots in cleaning and ensuring that the filter cloth below the side pressure block 423 is also cleaned. Furthermore, during the above process, due to the brush block 407 pressing against the filter cloth... The surface of filter cloth 10 is squeezed and scrubbed, and the filter cloth 10 on the side of the adsorbed U-shaped scraper assembly will temporarily lose its adsorption force and will easily sink to the side of filter plate 20. During the process of the transverse brush plate 408 being pulled out horizontally from the side pressure block 423, the instantaneous negative pressure formed at the lower end of the side pressure block 423, plus the friction between the transverse brush plate 408 and the two ends of the filter cloth 10, can instantly straighten the sunken filter cloth 10 horizontally. On the one hand, it can prevent the filter cloth 10 from sinking, and on the other hand, it can complete the shaking of the filter cloth during the tightening process, thereby improving the cleaning effect.
[0061] III. Cobalt carbonate collection and wastewater recycling:
[0062] The mud washed by the horizontal scraper 422, the transverse brush 408, and the brush block 407 will fall onto the filter plate 502 above the water tank 501 below. The water pump 503 then pressurizes the filtered water through the water pipe 504 into the spray assembly 403 for reuse.
[0063] Furthermore, as the rack 505 on the mounting bracket 402 moves further down, it drives the second rotating rod 507, where the gear 506 is located, to rotate, thereby driving the second cam 508 on it to rotate. The second cam 508 drives the filter plate 502 to tilt and shake up and down, shaking off the solid waste of cobalt carbonate on it from one side into the collection frame 509 for centralized collection.
[0064] This invention enables the differentiated cleaning of deposits of different sizes. First, a U-shaped scraping component is used to scrape off the larger protruding deposits on the surface of the filter cloth. Then, an oscillating cleaning component alternates between "adsorption mode" and "brushing mode," allowing the brush block to clean the small pieces of the filter cloth surface that have been lifted off the filter plate and the deposits adsorbed in the pores during the oscillation process, thereby improving the cleaning efficiency of the filter cloth.
[0065] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
