Description

Technical Field

[0001] This invention relates to the field of resource recycling technology for waste ternary lithium batteries, and more specifically, to an automated plate and frame filter press for stripping dry waste ternary lithium battery powder. Background Technology

[0002] With the rapid expansion of the new energy vehicle industry, the recycling and processing of retired ternary lithium batteries has become a key link in ensuring resource recycling and ecological environment safety. After pretreatment such as crushing and sorting, the waste ternary lithium batteries will form powder containing valuable metals such as lithium, cobalt, and nickel. This powder needs to be separated by solid-liquid separation to remove residual electrolyte and cleaning liquid in order to meet the requirements of subsequent purification processes for material moisture content and purity. Plate and frame filter presses have become the core application equipment in this process due to their high solid-liquid separation precision. However, existing plate and frame filter presses still have several technical shortcomings in the process of processing waste ternary lithium battery powder, making it difficult to meet the requirements of high efficiency and environmental protection in recycling processes. The specific problems are as follows: Existing plate and frame filter presses mostly use a plate-pulling trolley to complete the plate and frame separation operation. The plate-pulling trolley needs to separate multiple plates and frames one by one to achieve automatic drop of filter cake between the plates and frames. However, on the one hand, the one-by-one separation operation takes a long time and cannot be adapted to the continuous operation rhythm of large-scale recycling production lines. On the other hand, the dry material of waste ternary lithium battery powder has the characteristics of strong adhesion and fine particles. The filter cake is easy to adhere tightly to the inner wall of the plate and frame or the surface of the filter cloth, and frequently causes jamming that cannot be automatically removed. In the end, the staff has to manually peel off the filter cake, which further increases the labor intensity and significantly reduces the overall processing efficiency. Furthermore, during the filtration process of battery powder, the equipment discharges a large amount of wastewater. This wastewater not only contains incompletely separated battery powder but also contains a significant amount of acidic substances due to residual electrolyte components. On the one hand, if this wastewater is discharged directly, it will cause water pollution and the loss of valuable metal resources, failing to meet environmental emission standards. On the other hand, if the wastewater containing acidic substances is not treated in a timely and effective manner, it can easily cause corrosion damage to the factory's conveying pipelines and other production machinery, increasing equipment maintenance costs and the risk of failure, and affecting the stable operation of the production line.

[0003] Based on this, the present invention discloses an automated plate and frame filter press for stripping dry waste ternary lithium battery powder. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this automated waste ternary lithium battery powder dry material stripping plate and frame filter press, through the cooperation between filter plates, three-section telescopic tubes, separation springs, scrapers and ejector plates, multiple filter plates are automatically separated by an appropriate distance by the elastic force of the separation springs after the extrusion push plate moves away from the filter plate. When two adjacent filter plates separate and merge, the scraper can scrape one side of the filter plate and continuously knock on the filter plate while scraping, thereby achieving the function of stripping the filter cake. This can effectively solve the problems of low plate and frame separation efficiency and high manual dependence caused by filter cake jamming. 2. In this automated waste ternary lithium battery powder dry material stripping plate and frame filter press, through the cooperation of water tank, partition, filter plate, pressure plate, metering pipe and moving ring, the wastewater discharged during the filtration process enters the water tank. The pressure plate pushes the wastewater to accelerate filtration, and the piston plate moves during the filtration process. The metering pipe draws the chemical solution from the storage tank into the water tank to mix with the wastewater, achieving the effect of wastewater treatment and quantitative chemical dosing. This effectively solves the problems of difficult wastewater disposal during filtration and the risks of environmental protection and equipment corrosion. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Plate and frame filter presses have low separation efficiency, filter cake jamming leading to high reliance on manual labor, and difficult wastewater treatment, posing environmental and equipment corrosion risks.

[0019] Therefore, this invention provides an automated plate and frame filter press for stripping dry waste ternary lithium battery powder. (See also...) Figures 1-15 As shown, it includes a mounting frame 1, on which a hydraulic push rod 4 is mounted. A pressing push plate 2 is fixedly connected to the telescopic end of the hydraulic push rod 4. A grouting pipe 3 is mounted on the end face of the mounting frame 1 away from the hydraulic push rod 4. Several evenly distributed filter press plates 5 are arranged inside the mounting frame 1. A connecting hole 6 is opened on the end face of the filter press plate 5, matching the grouting pipe 3. Support plates 7 are fixedly connected to both sides of the filter press plate 5.

The stripping assembly also includes a vibration mechanism for vibrating the filter press plate 5, which works in conjunction with the stripping assembly. A wastewater treatment assembly is located outside the mounting frame 1. The wastewater treatment assembly can filter the wastewater discharged during the filtration process. The wastewater treatment assembly also includes a quantitative dosing mechanism, which works in conjunction with the wastewater treatment assembly.

[0020] The mounting bracket 1 and hydraulic push rod 4 in this technical solution are common devices in the prior art. Their usage methods and working principles are common knowledge among those in the field, so they will not be described in detail in this technical solution. In addition, the filter press plate 5 in this technical solution needs to be installed with filter cloth to cooperate with the filter press plate 5 during use.

[0021] See Figures 1-9As shown, the peeling assembly includes a first receiving groove 9, three telescopic tubes 10, a separation spring 11, a top plate 12, a rectangular groove 13, and a second receiving groove 14. The support plate 7 has a first receiving groove 9 on its end face away from the pressing plate 2. Three telescopic tubes 10 are fixedly connected to the inner side of the first receiving groove 9. The filter press plate 5 has a top plate 12 on both sides of its end face away from the support plate 7. The top plate 12 has a second receiving groove 14 on its end face opposite to the support plate 7. One end of the three telescopic tubes 10 extends into the second receiving groove 14 and is fixedly connected to its inner side. A separation spring 11 is sleeved on the outer side of the three telescopic tubes 10. The two ends of the separation spring 11 are fixedly connected to the inner sides of the second receiving groove 14 and the first receiving groove 9, respectively. Rectangular grooves 13 are provided at the top and bottom of the top plate 12. The peeling assembly also includes a transmission inclined rod 15, an extension shaft 16, a rack 17, a limiting protrusion 18, a first fixed seat 19, a swing gear 20, and a brush 22. Along with the rubber scraper 23, two rectangular grooves 13 on the same top plate 12 are movably connected to the inner sides of the two transmission inclined rods 15. The two transmission inclined rods 15 are rotatably connected to the side of the filter press plate 5 near the side of the filter press plate 5. The end of the extended shaft 16 away from the transmission inclined rod 15 is fixedly connected to the rack 17. The side of the filter press plate 5 near the top and bottom is fixedly connected to the limiting protrusions 18. The rack 17 is slidably connected to the inner side of the limiting protrusions 18. The side of the filter press plate 5 near the top and bottom is fixedly connected to the first fixed seat 19. The end face of the first fixed seat 19 is movably connected to the swing gear 20 through the rotating shaft. The swing gear 20 meshes with the rack 17. The end of the rotating shaft on the swing gear 20 away from the first fixed seat 19 is fixedly connected to the scraper 21. The end face of the scraper 21 opposite to the support plate 7 is fixedly connected to the evenly distributed brush 22. The side of the scraper 21 away from the transmission inclined rod 15 is fixedly connected to the rubber scraper 23. The rubber scraper 23 is set at an inclination.

[0022] See Figures 3-6As shown, the vibration mechanism includes a second fixed base 24, a rotating gear 25, a lever 26, a catapult plate 27, and an L-shaped lever 28. The second fixed base 24 is fixedly connected to the side of the filter press plate 5 away from the scraper 21 near both the top and bottom. The rotating gear 25 is movably connected to the end face of the second fixed base 24, and the rotating gear 25 meshes with the rack 17. The lever 26 is fixedly connected to the end face of the rotating gear 25 away from the second fixed base 24. The catapult plate 27 is slidably connected to the side of the filter press plate 5 away from the scraper 21 near both the top and bottom. The L-shaped lever 28 is slidably connected to the side of the catapult plate 27 away from the filter press plate 5 near the top. The L-shaped lever 28 matches the lever 26. The vibration mechanism also includes a return spring 29. The filter press 27 consists of an ear plate 30, a spring 31, a movable impact block 32, a fixed impact block 33, and a fixed plate 34. The ear plate 30 is fixedly connected to the side of the ejector plate 27 away from the filter press 5. A return spring 29 is fixedly connected between the ear plate 30 and the inner side of the L-shaped lever 28. Two fixed plates 34 are symmetrically fixedly connected to the side of the filter press 5 away from the swing gear 20. A spring 31 is fixedly connected between the fixed plate 34 and the adjacent ejector plate 27. A movable impact block 32 is fixedly connected to the end face of the ejector plate 27 away from the rotating gear 25. Two fixed impact blocks 33 are symmetrically fixedly connected to the side of the filter press 5 away from the swing gear 20 near the movable impact block 32. The fixed impact blocks 33 abut against the movable impact blocks 32.

[0023] During operation, the hydraulic push rod 4 is first activated to push the extrusion push plate 2 towards the filter press plate 5. The extrusion push plate 2 pushes multiple filter press plates 5 together. When the distance between the multiple filter press plates 5 decreases, the two top plates 12 on the filter press plate 5 furthest from the extrusion push plate 2 contact the mounting frame 1, while the remaining top plates 12 contact the adjacent support plates 7. As the extrusion push plate 2 continues to push, the separation springs 11 on the multiple filter press plates 5 are compressed, causing the three telescopic tubes 10 to retract synchronously. These top plates 12 then move towards the support plates 7, causing the two transmission inclined rods 15 to swing outwards, pushing the rack 17 away from the support plates 7. When the rack 17 slides outwards, it drives the swing gear 20 to rotate clockwise. The swing gear 20 drives the upper scraper 21 to swing upwards, while the lower swing gear 20 drives the scraper 21 to swing downwards. This cleans the filter cloth on both end faces of the filter press plates 5. When two adjacent filter press plates 5 are... As they approach, the upper scraper 21 rotates to the upper side of the filter press plate 5, while the lower scraper 21 rotates to the lower side of the filter press plate 5. This does not affect the merging of two adjacent filter press plates 5. After all the filter press plates 5 are merged, grout can be injected through the grouting pipe 3. The battery powder in mud state will fill the space between multiple adjacent filter press plates 5 through the connecting hole 6 in sequence. After the mud is filled, the grouting pressure will be increased. At this time, the grouting will be stopped. After standing for a specified time, the multiple filter press plates 5 can be separated. After standing, the hydraulic push rod 4 will retract and pull the push plate 2 away from the filter press plate 5. The rebound force of the separation spring 11 pushes the top plate 12, causing the two transmission inclined rods 15 to pull the rack 17 downward. The rack 17 drives the swing gear 20 to reverse. At this time, the upper scraper 21 will swing downward to scrape the filter cake formed by the filter press, while the lower scraper 21 will swing upward, thereby forcing the filter cake to separate from the filter press plate 5.

[0024] Furthermore, when the oscillating gear 20 reverses, that is, when the multiple filter plates 5 separate, the oscillating gear 20 on the side away from the scraper 21 drives the paddle 26 to reverse, causing the paddle 26 to move the L-shaped paddle 28 and the ejector plate 27 downwards, compressing the ejector spring 31. As the paddle 26 continues to rotate, it will suddenly lose contact with the L-shaped paddle 28. Simultaneously, the rebound force of the ejector spring 31 will push the ejector plate 27 and the movable impact block 32 upwards to impact the fixed impact block 33. The fixed impact block 33 will transmit the impact force to the filter plates 5, thereby achieving the effect of vibration. This is achieved through multiple paddles 26 rotating a large number of times. The rotating gear 25 causes the movable impact block 32 to repeatedly impact the fixed impact block 33. The vibration can improve the separation effect of the filter cake and the filter plate 5. Conversely, when the swing gear 20 rotates forward, that is, when multiple filter plates 5 are combined, the swing gear 20 drives the paddle 26 to rotate forward, which will also paddle the L-shaped paddle 28. At this time, the L-shaped paddle 28 will slide towards the far ear plate 30 and stretch the return spring 29. When the paddle 26 loses contact with the L-shaped paddle 28, the return spring 29 will pull the L-shaped paddle 28 back to the initial position. In this way, the ejector plate 27 will not vibrate the filter plates 5 when multiple filter plates 5 are combined.

[0025] Two adjacent filter press plates 5 are grouped together, with the scraper 21 of one filter press plate 5 on the front and the scraper 21 of the other filter press plate 5 on the rear. This prevents the scrapers 21 from colliding when the two filter press plates 5 are joined together. The rubber scraper strips 23 on the scraper 21 can clean the filter cloth near the grooves of the filter press plate 5. The brush 22 can clean the surface of the filter cloth after the filter cake falls off, allowing particles adhering to the filter membrane to fall off. In this technical solution, the toothed strips 17 on the same filter press plate 5 have different shapes. The rack 17 and swing gear 20 near the scraper 21 are wider because they bear greater pressure than the rack 17 on the other side. The rotating gear 25 and rack 17 near the ejector plate 27 are narrower. The rack 17 near the rotating gear 25 is slidably connected to the filter press plate 5 so that it will not tilt during operation. The second storage groove 14 and the first storage groove 9 serve to store the three-section telescopic tube 10. When the two filter press plates 5 are combined, the top plate 12 will protrude from the side of the filter press plate 5 to avoid collision and failure to combine.

[0026] See Figures 10-15As shown, the wastewater treatment assembly includes a water tank 35, partitions 36, filter plates 37, and handles 38.

The water tank 35 and the connecting pipe 61 are internally connected. Several filter press plates 5 are all installed with filter press drain pipes 62 near the sewage collection pipe 60. The bottom end of the filter press drain pipe 62 is fixedly connected to the outside of the sewage collection pipe 60. The filter press drain pipe 62 is internally connected to the filter press drain pipe 62 and the hydraulic push rod 4.

[0027] During operation, when the extrusion pusher 2 presses the filter press plate 5, it also pushes the vertical plate 42 and the pressure rod 41 through the L-shaped linkage plate 63. Simultaneously, the pressure rod 41 pushes the pressure plate 40 to move towards the partition plate 36. During the filtration process, the slurry will undergo solid-liquid separation. The separated liquid will pass through the filter cloth into the filter press plate 5, and then enter the sewage collection pipe 60 through the filter drain pipe 62. The sewage collection pipe 60 will then transport the filtered liquid to the water tank 35 through the connecting pipe 61. When the filtration is completed and the extrusion pusher 2 moves away from the filter press plate 5, it will also pull the pressure plate 40 away from the partition plate 36 through the L-shaped linkage plate 63, the vertical plate 42, and the pressure rod 41. Because there is sewage inside the water tank 35, when the pressure plate 40 is displaced, the sewage will push the circular opening 43 to push the valve plate 44 away from the pressure plate 40. At this time, the sewage will enter the space between the pressure plate 40 and the partition plate 36 through the gap between the circular opening 43 and the valve plate 44 and the pressure plate 40. Then the sewage will be filtered through the partition plate 36 and the filter plate 37. When the push plate 2 pushes the filter plate 5, it will also move again towards the partition plate 36 through the L-shaped linkage plate 63. At this time, the valve plate 44 will be in contact with the pressure plate 40 and close the circular opening 43. The pressure plate 40 will push the sewage to pass through the partition plate 36 and the filter plate 37 more quickly, thus achieving the effect of accelerated filtration.

[0028] To further treat the wastewater, chemicals need to be added to the water tank 35 and mixed with the wastewater to ensure that the acidity or alkalinity of the wastewater meets the discharge standards. When the pressure rod 41 slides to the outside of the water tank 35, it pulls the piston rod 50 and piston plate 49 through the fixed rod 59. At this time, the first one-way valve 51 opens and the second one-way valve 53 closes. The chemicals in the storage tank 47 are drawn into the metering tube 48 through the suction tube 52 by the negative pressure. Then, when the pressure rod 41 slides to the inside of the water tank 35, it pushes the movable ring 55 to drive the piston rod 50 and piston plate 49 to slide towards the first one-way valve 51. At this time, the first one-way valve 51 closes and the second one-way valve 53 opens. In this way, the chemicals in the metering tube 48 will enter the water tank 35 through the second one-way valve 53 and the outlet pipe 54 to mix with the wastewater. The metering tube 48 enables quantitative dosing.

[0029] In this technical solution, the sewage collection pipe 60 is closed at both ends, and sewage is transported to the water tank 35 only through the connecting pipe 61. The filter drain pipe 62 is a flexible hose, which can change its bending degree with the filter plate 5 to prevent it from breaking. The filter plate 37 in this technical solution is a common filter accessory. Different filter plates 37 with different functions can be selected according to actual needs. When replacing, it can be pulled out by the handle 38.

[0030] See Figures 10-13As shown, the quantitative dosing mechanism includes a storage tank 47, a metering tube 48, a piston plate 49, a piston rod 50, a first one-way valve 51, and a pipette 52. The storage tank 47 is fixedly connected to the top of the water tank 35. The metering tube 48 is fixedly connected to the top of the water tank 35 near the storage tank 47. The piston plate 49 is slidably connected to the inner side of the metering tube 48. The piston rod 50 is located on the outer side of the metering tube 48. One end of the piston rod 50 near the metering tube 48 passes through the metering tube 48 and is slidably connected to it. One end of the piston rod 50 is fixedly connected to the piston plate 49. The first one-way valve 51 is installed on the end of the metering tube 48 away from the piston rod 50. The pipette 52 is installed on the end of the first one-way valve 51 away from the metering tube 48. The end of the pipette 52 away from the first one-way valve 51 is fixedly connected to the outer side of the storage tank 47. The storage tank 47 and the pipette... The internal components of the metering tube 48 are interconnected. The metering dosing mechanism also includes a second check valve 53, an outlet pipe 54, a movable ring 55, a screw hole 56, a positioning bolt 57, a transmission ring 58, and a fixing rod 59. The second check valve 53 is installed on the outside of the metering tube 48 near the first check valve 51. The outlet pipe 54 is installed at the end of the second check valve 53 away from the metering tube 48. The end of the outlet pipe 54 away from the metering tube 48 passes through the water tank 35 and is connected to the inside of the water tank 35. The movable ring 55 is sleeved on the outside of the piston rod 50. A screw hole 56 is opened on the outside of the movable ring 55. A positioning bolt 57 is threaded on the inside of the screw hole 56. The fixing rod 59 is sleeved on the outside of the piston rod 50 away from the movable ring 55. The transmission ring 58 is fixedly connected to the bottom of the fixing rod 59. The bottom of the transmission ring 58 is fixedly connected to the pressure rod 41 away from the water tank 35.

[0031] During operation, the dosage of the drug can be adjusted according to actual needs. When it is necessary to adjust the dosage, first loosen the positioning bolt 57, and slide the movable ring 55 to the left or right. The closer the movable ring 55 is to the metering tube 48, the less drug is dispensed. Conversely, the farther the movable ring 55 is from the metering tube 48, the more drug is dispensed. This is because the dosage of drug inhaled into the metering tube 48 is the same each time. When the fixed rod 59 slides towards the water tank 35, the earlier it contacts the movable ring 55, the longer the piston rod 50 is pushed, and vice versa. The above operation can effectively improve the convenience of use.

[0032] The chemical reagents in the storage tank 47 can be placed as needed, generally flocculants and alkali solutions. The reagents can be added synchronously with the filter press through the metering tube 48, and the dosage can be adjusted, making it more convenient to use.

[0033] In summary, this effectively solves the problems of low plate and frame filter separation efficiency, high reliance on manual labor due to filter cake jamming, and difficulties in wastewater treatment by filter press, as well as the risks of environmental protection and equipment corrosion.

[0034] Working Principle: In use, the filter press plates 5 are first placed sequentially on the mounting frame 1, aligning the grouting pipe 3 with the connecting holes 6 on the filter press plates 5. Next, an appropriate amount of chemical agent is placed in the storage tank 47, and then it can be used normally. The grouting pipe 3 is connected to the conveying pipe for transporting mud. The flange pipe 39 can be used to install the conveying pipeline. Then it can be used normally. First, the hydraulic push rod 4 is activated to push the extrusion push plate 2 towards the filter press plates 5. The extrusion push plate 2 pushes multiple filter press plates 5 together. When the distance between the multiple filter press plates 5 decreases... At hour, the two top plates 12 on the filter press plate 5 away from the extrusion pusher plate 2 abut against the mounting frame 1, while the remaining top plates 12 abut against the adjacent support plates 7. As the extrusion pusher plate 2 continues to push, the separation springs 11 on multiple filter press plates 5 are compressed, causing the three telescopic tubes 10 to contract synchronously. The top plates 12 will displace towards the support plates 7, causing the two transmission inclined rods 15 to swing outward and push the rack 17 to slide away from the support plates 7. When the rack 17 slides outward, it will drive the swing gear 20 to rotate clockwise, and the swing gear 20 will drive the upper scraper 2. The upper scraper 21 swings upwards, while the lower scraper 20 drives the scraper 21 to swing downwards. This cleans the filter cloth on both end faces of the filter press plate 5. When two adjacent filter press plates 5 are about to approach each other, the upper scraper 21 rotates to the upper side of the filter press plate 5, while the lower scraper 21 rotates to the lower side of the filter press plate 5. Therefore, it does not affect the merging of two adjacent filter press plates 5. After all the filter press plates 5 have merged, grout can be injected through the grouting pipe 3. The battery powder in mud state will sequentially fill the space between multiple adjacent filter press plates 5 through the connecting hole 6, and then fill the space. After the mud is added, the grouting pressure will increase. At this time, the grouting will be stopped. After a specified time of settling, the multiple filter plates 5 can be separated. After settling, the hydraulic push rod 4 will retract and pull the push plate 2 away from the filter plate 5. Simultaneously, the rebound force of the separation spring 11 will push the top plate 12, causing the two transmission inclined rods 15 to pull the rack 17 downward. The rack 17 will drive the swing gear 20 to reverse. At this time, the upper scraper 21 will swing downward to scrape the filter cake formed by the filter press, while the lower scraper 21 will swing upward, thereby forcing the filter cake to separate from the filter plate 5.

[0035] Furthermore, when the oscillating gear 20 reverses, that is, when the multiple filter plates 5 separate, the oscillating gear 20 on the side away from the scraper 21 drives the paddle 26 to reverse, causing the paddle 26 to move the L-shaped paddle 28 and the ejector plate 27 downwards, compressing the ejector spring 31. As the paddle 26 continues to rotate, it will suddenly lose contact with the L-shaped paddle 28. Simultaneously, the rebound force of the ejector spring 31 will push the ejector plate 27 and the movable impact block 32 upwards to impact the fixed impact block 33. The fixed impact block 33 will transmit the impact force to the filter plates 5, thereby achieving the effect of vibration. This is achieved through multiple paddles 26 rotating a large number of times. The rotating gear 25 causes the movable impact block 32 to repeatedly impact the fixed impact block 33. The vibration can improve the separation effect of the filter cake and the filter plate 5. Conversely, when the swing gear 20 rotates forward, that is, when multiple filter plates 5 are combined, the swing gear 20 drives the paddle 26 to rotate forward, which will also paddle the L-shaped paddle 28. At this time, the L-shaped paddle 28 will slide towards the far ear plate 30 and stretch the return spring 29. When the paddle 26 loses contact with the L-shaped paddle 28, the return spring 29 will pull the L-shaped paddle 28 back to the initial position. In this way, the ejector plate 27 will not vibrate the filter plates 5 when multiple filter plates 5 are combined.

[0036] When the extrusion pusher 2 extrudes the filter press plate 5, it also pushes the vertical plate 42 and the pressure rod 41 through the L-shaped linkage plate 63. Simultaneously, the pressure rod 41 pushes the pressure plate 40 to move towards the partition plate 36. During the filtration process, the slurry will undergo solid-liquid separation. The separated liquid will pass through the filter cloth into the filter press plate 5, and then through the filter drain pipe 62 into the sewage collection pipe 60. The sewage collection pipe 60 will then transport the filtered liquid to the water tank 35 through the connecting pipe 61. When the filtration is completed and the extrusion pusher 2 moves away from the filter press plate 5, it will also pull the pressure plate 40 away from the partition plate 36 through the L-shaped linkage plate 63, the vertical plate 42, and the pressure rod 41. At this time, because the water... Because there is sewage inside the tank 35, when the pressure plate 40 is displaced, the sewage will push the circular opening 43 to push the valve plate 44 away from the pressure plate 40. At this time, the sewage will enter the space between the pressure plate 40 and the partition plate 36 through the gap between the circular opening 43 and the valve plate 44 and the pressure plate 40. Then the sewage will be filtered through the partition plate 36 and the filter plate 37. When the push plate 2 pushes the filter plate 5, it will also move again towards the partition plate 36 through the L-shaped linkage plate 63. At this time, the valve plate 44 will be in contact with the pressure plate 40 and close the circular opening 43. The pressure plate 40 will push the sewage to pass through the partition plate 36 and the filter plate 37 more quickly, thus achieving the effect of accelerated filtration.

[0037] To further treat the wastewater, chemicals need to be added to tank 35 and mixed with the wastewater to ensure the wastewater's pH level meets discharge standards. When the pressure rod 41 slides outward from tank 35, it pulls piston rod 50 and piston plate 49 via fixed rod 59. At this time, first check valve 51 opens and second check valve 53 closes. Negative pressure draws the chemicals from storage tank 47 into metering tube 48 through suction tube 52. Then, when the pressure rod 41 slides inward from tank 35, it pushes movable ring 55, causing piston rod 50 and piston plate 49 to slide towards first check valve 51. At this time, first check valve 51 closes and second check valve 53 opens, allowing the chemicals in metering tube 48 to pass through second check valve 53 and... The liquid outlet pipe 54 enters the water tank 35 and mixes with the sewage. A quantitative dosage can be achieved through the metering pipe 48, and the dosage can be adjusted according to actual needs. When adjusting the dosage, first loosen the positioning bolt 57, then slide the movable ring 55 to the left or right. The closer the movable ring 55 is to the metering pipe 48, the less medication is dispensed; conversely, the farther the movable ring 55 is from the metering pipe 48, the more medication is dispensed. This is because the dosage drawn into the metering pipe 48 is the same each time. When the fixed rod 59 slides towards the water tank 35, the earlier it contacts the movable ring 55, the longer the piston rod 50 is pushed, and vice versa. This operation effectively improves ease of use.
