Description

Technical Field

[0001] The present application relates to the technical field of electroplating liquid filtration, and in particular to an electroplating device for filtering out impurities. Background Art

[0002] During the electroplating process, impurities gradually accumulate in the plating bath due to electrolytic reactions, anode dissolution, and external contamination. Metal ions (such as copper, iron, and zinc) are particularly harmful. These impurities can cause defects such as burrs, pitting, and nodules in the plated layer, seriously affecting the surface quality and mechanical properties of the plated parts.

[0003] Currently, the electroplating industry generally uses static filtration with filters to remove impurities from the plating solution. This involves placing the filter at the bottom of the plating tank, allowing impurities to settle on the filter surface by gravity, and then periodically removing the filter using a hoist for cleaning. However, relying solely on natural settling of impurities in the plating solution not only slows filtration but also easily clogs the filter, requiring frequent replacement and downtime. This can affect the continuity of the production process and reduce production efficiency. Summary of the Invention

[0004] In order to reduce the possibility of filter clogging and ensure the continuity of the production process, the present application provides an electroplating device for filtering out impurities.

[0005] The present application provides an electroplating device for filtering out impurities using the following technical solution: An electroplating device for filtering out impurities, comprising an electroplating tank; A box body, wherein a liquid inlet is provided on the box body, and a filtering mechanism is provided inside the box body; A conveying mechanism is provided between the electroplating tank and the housing, and is used to convey the electroplating liquid in the electroplating tank to the housing, and to convey the electroplating liquid after filtering in the housing to the electroplating tank; The filtering mechanism includes a power part, a rotating drum, a sprocket, a chain, a filter screen and a collecting box. Two rotating drums are provided and both are rotatably connected to the box body. The sprockets are provided at both ends of the rotating drum. The chain is wound between the sprockets on the two rotating drums. Two chains are provided and are arranged at intervals at both ends of the rotating drum. The filter screen is provided along the length direction of the chain and fixedly connected between the two chains. The filter screen is located below the liquid inlet. The collecting box is located at one end of the filter screen and is used to collect impurities falling from the outside of the filter screen. The power part is used to drive the rotating drum to rotate.

[0006] By adopting the above technical solution, the conveying mechanism conveys the plating liquid in the plating tank to the box, filters out impurities in the plating liquid through the filter, and then conveys the filtered plating liquid to the plating tank, thereby purifying the plating liquid in the plating tank, which helps to ensure the plating quality of the plated parts; the power part drives the drum to rotate and drives the filter to circulate, and when the filter is running, the impurities on the outside can be conveyed to the collection box, thereby realizing continuous cleaning of the filter, making it difficult for impurities to accumulate on the filter and cause blockage, thereby ensuring the continuity of the production process; compared with fixed filters, the structure of the present application does not require shutdown for cleaning and replacement, which helps to ensure work efficiency; in addition, the continuous operation of the filter can prevent the fallen plating liquid from concentrating on one part of the filter for filtration, thereby avoiding local overload and helping to extend the service life of the filter.

[0007] Optionally, a scraper is provided on the box body, and the scraper is located above the collecting box. The scraper is arranged at an angle, and the higher end of the scraper is against the filter screen outside the drum.

[0008] By adopting the above technical solution, the scraper abuts against the filter screen outside the drum, which can scrape off the impurities on the filter screen and make them fall into the collection box, reducing the accumulation of impurities on the filter screen and thus reducing the possibility of filter screen clogging.

[0009] Optionally, the scraper is slidably connected to the side wall of the box, and a spring is connected between the scraper and the side wall of the box, and the spring makes the end of the scraper press against the filter screen outside the drum.

[0010] By adopting the above technical solution, the elastic action of the spring ensures good contact between the scraper and the filter screen. Even if the filter screen vibrates or deforms slightly during operation, the scraper can adaptively adjust and always maintain the function of efficiently scraping away impurities, thereby better ensuring the continuity of the production process and enhancing the overall filtering performance of the device.

[0011] Optionally, the filter is elastic, and a fan is provided on the outer wall of the box above the filter, with the air outlet side of the fan facing the filter, so that when the fan blows air towards the filter, the upper layer of the filter sinks downward under the action of the wind, the filter is deformed, and the aperture of the upper filter is larger than the aperture of the lower filter.

[0012] By adopting the above technical solution, the fan blows air to the elastic filter, causing the upper layer of the filter to sink downward and deform. The aperture of the upper filter is larger than that of the lower filter. This structure is conducive to the effective filtration of impurities of different sizes at filters with different apertures, thereby improving the filtration effect of impurities in the electroplating solution. While ensuring the filtration efficiency, it reduces the possibility of clogging of the single aperture filter; the action of wind causes the upper filter to produce a downward concave deformation, and the concave filter can better receive the electroplating solution, making it difficult for the electroplating solution to fall from both sides of the filter, thereby ensuring the filtration effect of the electroplating solution; in addition, the sticky impurities in the electroplating solution are easy to adhere to the filter, and the mechanical action of the filter stretching-contracting-stretching can automatically peel off the surface impurities, weakening the adhesion of the sticky impurities, thereby making it easier to clean up the sticky impurities.

[0013] Optionally, a heating element is provided inside the box, and the heating element is located on the air outlet side of the fan.

[0014] By adopting the above technical solution, the heating element is located on the air outlet side of the fan, which can convert the wind blowing toward the filter into hot air, accelerate the evaporation of water in the electroplating solution, further prevent impurities from clogging the filter, and help impurities fall off the filter into the collection box faster.

[0015] Optionally, a support grid is provided inside the box body, and the support grid is located below the filter screen, and the top wall of the support grid is against the bottom wall of the lower filter screen.

[0016] By adopting the above technical solution, the supporting grid can support the filter screen in the lower layer. Therefore, even if the filter screen in the lower layer is impacted by the falling electroplating liquid, it is not easy to produce large deformation, thereby ensuring the stability of the aperture of the filter screen in the lower layer and helping to ensure the filtering effect.

[0017] Optionally, a guide plate is fixedly connected to the inner wall of the box, and the guide plate is located between the upper and lower layers of the filter. Two guide plates are provided and are symmetrically arranged. The ends of the two guide plates close to each other are inclined downward, and a gap is provided between the ends of the two guide plates close to each other for the electric plating solution to fall. A discharge hole is provided on the inner wall of the box on the side close to the top of the guide plate.

[0018] By adopting the above technical solution, the plating liquid that passes through the upper filter can fall onto the lower filter through the gap between the two guide plates, so that the plating liquid can fall more concentratedly on the middle of the lower filter, which helps to ensure the filtering effect; in addition, the guide plate can guide the incoming wind, so that the wind blown out by the fan can flow along the direction of the two guide plates after passing through the upper filter, and then be discharged outward through the discharge hole, thereby reducing the wind force blowing on the lower filter and ensuring the stability of the aperture of the lower filter; the guide plate can also reduce the splashing of the plating liquid and keep the inside of the box clean.

[0019] Optionally, an adsorption assembly is provided at the end of the filter away from the collection box, and the adsorption assembly includes a dust suction tube and a dust suction piece. The dust suction tube is fixedly connected to the box body, and the dust suction tube and the rotating drum away from the end of the collection box are coaxially arranged and rotatably connected. A cavity is provided inside the rotating drum, and a dust suction hole connected to the internal cavity is opened on the rotating drum. One end of the dust suction tube is connected to the cavity inside the rotating drum, and the other end of the dust suction tube is connected to the dust suction piece, so that the dust suction piece sucks impurities inside the filter through the dust suction tube and the dust suction hole on the rotating drum.

[0020] By adopting the above technical solution, the dust suction piece can suck in impurities inside the filter through the dust suction pipe and the dust suction holes on the drum, and can remove impurities remaining inside the filter, thereby ensuring the normal operation of the drum.

[0021] Optionally, a spray assembly is provided on one side of the box body, and the spray assembly includes a connecting pipe, a first pump body and a water tank. The connecting pipe is fixedly connected to the side wall of the box body, the connecting pipe is located at one end of the filter screen close to the collection box, the connecting pipe is located inside the rotating drum, the first pump body is connected between the connecting pipe and the water tank, a drainage hole is opened on the connecting pipe on the side close to the scraper, and the rotating drum close to the side of the collection box is hollowed out.

[0022] By adopting the above technical solution, the first pump body can transport the water in the water tank to the connecting pipe, and then discharge it outward through the drainage hole, thereby flushing and cleaning the filter screen on the outside of the drum, and flushing out the debris in the filter screen, thereby further reducing the possibility of the filter screen being blocked; the water sprayed from the connecting pipe can also flush out the debris on the top surface of the scraper, making it difficult for debris to accumulate on the scraper, thereby ensuring the cleaning effect of the scraper; the hollow drum design enables the spray water to better contact the filter screen, enhances the flushing effect, and thus improves the filtering performance of the entire device; the spray water can also reduce the temperature of the filter screen to prevent material aging caused by hot air.

[0023] Optionally, the conveying mechanism includes a second pump body, a branch pipe, a delivery pipe, a third pump body and a drain pipe, the branch pipe is connected between the electroplating tank and the second pump body, multiple branch pipes are provided, and each branch pipe is connected to a different depth of the electroplating tank, one end of the delivery pipe is connected to the second pump body, and the other end of the delivery pipe faces the liquid inlet; the third pump body is connected between the box body and the drain pipe, and the end of the drain pipe away from the third pump body faces the electroplating tank.

[0024] By adopting the above technical solution, multiple branch pipes are connected to different depths of the electroplating tank, which can extract the electroplating liquid from different depths of the electroplating tank, and obtain the electroplating liquid containing impurities more comprehensively, and transport it to the box through the second pump body and the delivery pipe, which helps to improve the comprehensiveness of the impurity filtration of the electroplating liquid and enhance the purification effect of the electroplating liquid in the electroplating tank.

[0025] In summary, this application has the following beneficial technical effects: 1. The power parts drive the drum to rotate, driving the chain and filter to move, so that the impurities separated from the electroplating solution will continuously fall into the collection box, reducing the possibility of filter clogging and ensuring the continuity of the working process.

[0026] 2. The fan blows air to the elastic filter to deform it. The aperture of the upper filter is larger than that of the lower filter, which can achieve double filtration of the electroplating solution, making the filter less likely to be blocked, helping to better filter impurities and enhance the filtering effect.

[0027] 3. The dynamically operated filter helps to enhance the separation effect of impurities through mechanical vibration, making it difficult for impurities to adhere to or clog the filter, thereby ensuring the filtering effect of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following combination Figure 1-Figure 7 This application is described in further detail.

[0031] The present application discloses an electroplating device for filtering out impurities. Figure 1 The electroplating device for filtering out impurities includes an electroplating tank 1, a housing 2, and a conveying mechanism 4. The electroplating tank 1 is filled with electroplating liquid, and a workpiece can be placed in the electroplating tank 1 for electroplating. The conveying mechanism 4 is arranged between the electroplating tank 1 and the housing 2, and can convey the electroplating liquid from the electroplating tank 1 to the housing 2. After being filtered by the filtering mechanism 3 inside the housing 2, the liquid flows back into the electroplating tank 1, allowing the electroplating liquid to continuously circulate and filter, thereby removing impurities and ensuring the purity of the electroplating liquid.

[0032] Reference Figure 1 and Figure 2 The conveying mechanism 4 includes a second pump body 41, a branch pipe 42, and a delivery pipe 43. The second pump body 41 can be a centrifugal pump or a screw pump, depending on actual flow rate, head, and other requirements. Multiple branch pipes 42 are fixedly connected between the plating tank 1 and the input end of the second pump body 41. Each branch pipe 42 is connected to a different depth in the plating tank 1. This allows the plating solution to be drawn from different depths in the plating tank 1. This multi-depth extraction allows for more comprehensive filtration and purification of the plating solution. One end of the delivery pipe 43 is connected to the output end of the second pump body 41, while the other end is inserted into the liquid inlet 21 on the side wall of the housing 2 and extends into the interior of the housing 2. When the second pump body 41 is operating, the plating solution is drawn through the branch pipe 42 and then delivered to the interior of the housing 2 via the delivery pipe 43. These components work together to form an efficient plating solution delivery system, ensuring that the plating solution can be smoothly transported from the plating tank 1 to the housing 2 for filtration.

[0033] The delivery mechanism 4 also includes a third pump body 44 and a drainage pipe 45. The bottom of the tank 2 is provided with a liquid outlet 22, and the third pump body 44 is fixedly mounted at the liquid outlet 22. The input end of the third pump body 44 communicates with the interior of the tank 2, and the output end of the third pump body 44 is connected to the drainage pipe 45, the end of which faces the electroplating tank 1. Therefore, when the third pump body 44 is in operation, it can re-deliver the filtered electroplating liquid at the bottom of the tank 2 to the electroplating tank 1, helping to maintain the stability of the electroplating liquid level in the electroplating tank 1.

[0034] Reference Figure 2 and Figure 3The housing 2 is provided with a filtration mechanism 3 comprising a power element 31, a rotating drum 32, a sprocket 33, a chain 34, a filter screen 35, and a collection box 36. Two rotating drums 32 are provided, each rotatably connected to the inner wall of the housing 2. The axes of the rotating drums 32 are horizontal, and the two rotating drums 32 are spaced apart and parallel to each other. The rotating drums 32 are made of corrosion-resistant materials such as stainless steel to ensure they are not easily damaged in the electroplating solution. The installation of the rotating drums 32 must ensure smooth rotation, and the rotatable connection can be achieved using components such as bearings. Four sprockets 33 are provided, one for each rotating drum 32. Each rotating drum 32 is coaxially fixedly connected to a sprocket 33 at each end. The sprockets 33 and rotating drum 32 can be secured to each other using a key connection or other means to ensure synchronous rotation. A chain 34 is wound between the sprockets 33 on the two rotating drums 32. Two chains 34 are provided, spaced apart at each end of the rotating drum 32. The filter screen 35 is disposed along the length of the chains 34 and is fixedly connected between the two chains 34. The width of the filter screen 35 is equal to the distance between the two chains 34. The filter screen 35 is located below the liquid inlet 21. When the electroplating solution flowing from the liquid inlet 21 falls on the filter screen 35, the filter screen 35 can filter the electroplating solution.

[0035] Reference Figure 2 A slag outlet 23 is provided on one side of the housing 2. A collection box 36 is fixedly connected to the side wall of the housing 2 at the slag outlet 23. The collection box 36 is located below one end of the filter 35, and the opening of the collection box 36 faces upward. The collection box 36 can collect impurities that fall from the outside of the filter 35. The power member 31 is used to drive the rotating drum 32 to rotate. The power member 31 is a motor. The motor is fixedly connected to the side wall of the housing 2. The output shaft of the motor is coaxially fixedly connected to one of the rotating drums 32 through a coupling. When the motor rotates, it drives the rotating drum 32 to rotate, and then drives the chain 34 and the filter 35 to circulate. The filter 35 filters the fallen electroplating solution, and the filtered solid particulate impurities are blocked on the outside of the filter 35. Then, as the filter 35 operates, they are transported to the collection box 36. The debris in the collection box 36 can be emptied regularly. The various components of the filtering mechanism 3 cooperate with each other to realize the circulating operation of the filter 35, continuously filter the electroplating solution, and collect impurities in time, avoiding the problem of easy clogging of the traditional static filter 35.

[0036] A scraper 5 is installed at the slag outlet 23 of the housing 2, positioned above the collection box 36. The scraper 5 is tilted, with its higher end pointed. The pointed end of the scraper 5 abuts against the filter screen 35 on the outside of the drum 32. Made of a flexible material such as plastic or rubber, the scraper 5 effectively removes impurities from the filter screen 35 while minimizing scratches. While the filter screen 35 is in operation, the scraper 5 removes impurities from the outside of the filter screen 35, which then fall into the collection box 36, preventing them from adhering to and accumulating on the filter screen 35.

[0037] Furthermore, the scraper 5 is slidably connected to the side wall of the housing 2. A connecting block 51 is fixedly connected to the bottom wall of the scraper 5, and a guide hole is defined in the connecting block 51. A guide rod 25 is fixedly connected to the outer wall of the housing 2. The guide rod 25 is arranged at an angle and slides through the guide hole, allowing the scraper 5 to slide. A spring 6 is fixedly connected between the connecting block 51 and the outer wall of the housing 2. The spring 6 is sleeved on the outside of the guide rod 25 and is in a stretched state. This ensures that the tip of the scraper 5 always presses against the filter 35 on the outside of the drum 32. This ensures close contact between the scraper 5 and the filter 35, scraping impurities from the filter 35 and causing them to fall into the collection box 36.

[0038] Reference Figure 4 To further reduce the possibility of clogging of the filter 35, a spray assembly 12 is provided on one side of the housing 2. The spray assembly 12 comprises a connecting pipe 121, a first pump body 122, and a water tank 123. The connecting pipe 121 is located at the end of the filter 35 near the collection box 36. Both ends of the connecting pipe 121 are fixedly connected to support blocks 14, which are fixedly connected to the sidewall of the housing 2. The connecting pipe 121 is coaxially disposed within the drum 32. The water tank 123 is located outside the housing 2 and contains cleaning water. The first pump body 122 is disposed between the connecting pipe 121 and the water tank 123. The input end of the first pump body 122 communicates with the interior of the water tank 123, while the output end of the first pump body 122 communicates with one end of the connecting pipe 121. The end of the connecting pipe 121 away from the first pump body 122 is closed, allowing the first pump body 122 to transfer water from the water tank 123 to the connecting pipe 121.

[0039] Reference Figure 2 The connecting pipe 121 is provided with a plurality of drainage holes 1211, which are evenly spaced along the length of the connecting pipe 121. The drainage holes 1211 are located on the side of the connecting pipe 121 near the scraper 5. In addition, the rotating drum 32 near the side of the collection box 36 is hollowed out, so that water in the connecting pipe 121 can be sprayed outward through the drainage holes 1211. The sprayed water passes through the hollow rotating drum 32 and is sprayed onto the filter 35, thereby flushing the filter 35 and flushing the debris clogged in the mesh of the filter 35 into the collection box 36, thereby flushing and cleaning the filter 35.

[0040] Among them, the rotating drum 32 on the side close to the collection box 36 is hollowed out, and this rotating drum 32 is located on the outside of the connecting tube 121. The rotating drum 32 and the connecting tube 121 are spaced apart, so the rotation of the rotating drum 32 is unlikely to affect the connecting tube 121, which helps to ensure the normal operation of the spraying process of the connecting tube 121. This hollow rotating drum 32 includes two circular rings and multiple support rods fixedly connected between the two circular rings, and the multiple support rods are arranged in a circular array; further, multiple connecting rings coaxially arranged with the circular rings can be fixedly connected to the support rods, and the multiple connecting rings are evenly spaced along the length of the support rods. The setting of the connecting rings can enhance the support effect on the filter 35, while not affecting the spray cleaning effect of the connecting tube 121 on the filter 35. In other embodiments, this rotating drum 32 can also be configured as a hollow cylinder with multiple perforations on the outer wall.

[0041] Furthermore, in order to enhance the filtering effect of the filter screen 35, the filter screen 35 in this embodiment is elastic. The filter screen 35 is made of a composite woven material. The base material used to make the filter screen 35 is a highly elastic polymer fiber, such as polyurethane (PU), silicone rubber or thermoplastic elastomer (TPE), which provides reversible stretchability; stainless steel microfilaments or carbon fibers can be embedded inside to prevent excessive deformation; the warp and weft fibers are interwoven in a specific proportion to ensure that the pore size can be expanded when stretched.

[0042] Reference Figure 2 A fan 7 is fixedly mounted on the top wall of the box body 2. The fan 7 is located above the filter 35. The air outlet side of the fan 7 faces downward. The fan 7 can be a centrifugal fan, etc., which can provide sufficient wind force to deform the filter 35. A heating element 8 is also fixedly mounted on the inner wall of the top of the box body 2. The heating element 8 is located on the air outlet side of the fan 7. The heating element 8 is an electric heating tube. The heated wind can accelerate the flow of the electroplating solution and the separation of impurities. A mounting frame 13 is also fixedly connected to the top wall inside the box body 2. The mounting frame 13 is covered on the outside of the heating element 8. A plurality of exhaust holes 131 are provided on the bottom wall of the mounting frame 13. The mounting frame 13 plays a role in protecting the heating element 8. At the same time, the exhaust holes 131 can make the hot air blow evenly toward the filter 35.

[0043] The combination of the fan 7 and the heater 8 causes the upper filter 35 to sag downward and deform when subjected to the hot air. The aperture of the upper filter 35 becomes larger, which facilitates the faster passage of the plating solution through the filter 35 and speeds up the filtration process. This process can filter out impurities with larger particle sizes. The plating solution after one filtration penetrates between the upper and lower layers of the filter 35 and then falls downward through the lower filter 35. The lower filter 35 is not directly affected by the wind, so its aperture is smaller and can filter out impurities with smaller particle sizes. The two filtrations work together to enhance the filtration effect. The heated air can reduce the viscosity of the plating solution, help enhance the fluidity of the plating solution, and enhance the separation effect of impurities.

[0044] Reference Figure 4 and Figure 5 Furthermore, a support grid 9 is provided inside the box body 2. The support grid 9 is arranged horizontally and has a grid-shaped support structure inside. The support grid 9 is located below the filter 35. Under normal circumstances, the top wall of the support grid 9 is against the bottom wall of the lower filter 35, so that the support grid 9 can support the lower filter 35. Even if the electroplating liquid causes an impact on the lower filter 35 during the falling process, it is not easy to cause the lower filter 35 to be excessively deformed, so that the aperture of the lower filter 35 is distinguished from the aperture of the upper filter 35, ensuring the filtering effect. A handle 91 is fixedly connected to one side of the support grid 9, and a mounting hole 26 for the support grid 9 to slide into is provided on the side wall of the box body 2. The support grid 9 is slidably and detachably connected to the box body 2, and the support grid 9 can be regularly pulled out for cleaning.

[0045] Reference Figure 6 and Figure 7 A guide plate 10 is also fixedly connected to the inner wall of the box body 2, and the guide plate 10 is located between the upper and lower layers of the filter screen 35. The guide plate 10 is arranged along the length direction of the box body 2; there are two guide plates 10 and they are arranged symmetrically, and the ends of the two guide plates 10 that are close to each other are tilted downward, so that the two guide plates 10 are arranged in a V-shape. A gap is provided between the ends of the two guide plates 10 that are close to each other for the electroplating solution to fall, and a discharge hole 24 is provided on the inner wall of the box body 2 on one side near the top of the guide plate 10. Therefore, the guide plate 10 can guide the flow direction of the electroplating solution, so that the electroplating solution can fall more concentratedly to the middle of the lower filter screen 35, which helps to ensure the filtering effect. The guide plate 10 can also block the wind passing through the upper filter 35, so that this part of the wind can flow along the guide plate 10 and be discharged outward through the discharge hole 24, thereby reducing the blowing effect of the wind on the lower filter 35 and ensuring the stability of the filtering aperture of the lower filter 35.

[0046] Reference Figure 3 and Figure 4The end of the filter 35 away from the collection box 36 is provided with an adsorption assembly 11, which includes a dust suction pipe 111 and a dust suction part 112. The dust suction pipe 111 is fixedly connected to the housing 2. The dust suction pipe 111 and the rotary drum 32 at the end away from the collection box 36 are coaxially arranged and rotatably connected. A cavity is provided inside the rotary drum 32, and dust suction holes 321 that communicate with the internal cavity are opened on the outer wall of the rotary drum 32. There are multiple dust suction holes 321 arranged in a circular array. One end of the dust suction pipe 111 is connected to the cavity inside the rotary drum 32, and the other end of the dust suction pipe 111 is connected to the dust suction part 112, which is a vacuum cleaner. Therefore, the dust suction part 112 can suck impurities inside the filter 35 through the dust suction pipe 111 and the dust suction holes 321 on the rotary drum 32, thereby preventing the accumulation of impurities inside the filter 35 and helping to ensure the smooth rotation of the rotary drum 32. The dust suction pipe 111 and the rotating drum 32 are rotatably connected, so that when the rotating drum 32 rotates, the dust suction pipe 111 will not be driven to rotate, which helps to ensure the normal operation of the dust suction pipe 111.

[0047] The working principle of the electroplating device for filtering impurities according to the embodiment of the present application is as follows: the power member 31 drives the rotating drum 32 to rotate, driving the chain 34 and the filter 35 to operate continuously. At the same time, the fan 7 and the heating element 8 are activated, and the fan 7 blows hot air downward. The wind force causes the upper filter 35 to sag downward, deforming the upper filter 35 and expanding the aperture of the upper filter 35. The wind passing through the upper filter 35 can flow along the guide plate 10 and then be discharged through the discharge hole 24. Therefore, due to the obstruction of the upper filter 35 and the guidance of the guide plate 10, the lower filter 35 is less affected by the wind force, and the lower filter 35 remains in its original shape. Therefore, the aperture of the upper filter 35 is larger, which can perform initial filtration of the falling electroplating solution and filter out larger impurities. The aperture of the lower filter 35 is smaller, which can perform secondary filtration of the electroplating solution passing through the upper filter 35 and filter out smaller impurities. The electroplating liquid after being filtered twice falls to the bottom of the box 2 and is then transported back to the electroplating tank 1 for recycling.

[0048] As the filter 35 continues to operate, the scraper 5 scrapes off impurities on the outside of the filter 35, which fall into the collection box 36. Simultaneously, water in the connecting pipe 121 continuously sprays outward, thereby flushing and cleaning the filter 35, further reducing the possibility of clogging the filter 35. The dust collector 112 draws impurities from the inside of the filter 35 through the dust collection pipe 111 and the dust collection holes 321 on the drum 32, thereby preventing the accumulation of impurities inside the filter 35.

[0049] The above are optional embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
