[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1-6 As shown, this utility model discloses an electroplating waste liquid filtration and treatment device, including a treatment box 1 and a filter box 2. The treatment box 1 is equipped with a pretreatment mechanism. A ring plate 222 is fixedly connected to the inner wall of the filter box 2. A filter screen 221 is provided on the ring plate 222. A cleaning mechanism is provided on the filter screen 221. The cleaning mechanism includes a first connecting block 231 rotatably connected to the filter screen 221 via a bearing. A scraper 23 is fixedly connected to the outer wall of the first connecting block 231. The bottom of the scraper 23 contacts the surface of the filter screen 221. A second motor 234 is fixedly connected to the bottom of the filter box 2. The output shaft of the second motor 234 is rotatably connected to the bottom of the filter box 2 via a bearing. A rotating shaft 233 is fixedly connected to the output shaft of the second motor 234. A second connecting block 232 is fixedly connected to the top of the rotating shaft 233. The first connecting block 231 and the second connecting block 232 are inserted into each other.

[0029] During operation, to prevent the activated carbon filter screen 221 from becoming clogged due to excessive accumulation of impurities, the first connecting block 231 and the second connecting block 232 on the filter screen 221 are inserted together during installation. Then, during the filtration process, the second motor 234 needs to be turned on. The output shaft of the second motor 234 drives the rotating shaft 233 to rotate, which in turn drives the second connecting block 232 to rotate. The second connecting block 232 then drives the first connecting block 231 to rotate, which in turn drives the scraper 23 to rotate. The rotation of the scraper 23 scrapes away the impurities on the filter screen 221, preventing the mesh of the filter screen 221 from becoming clogged and affecting filtration.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, a second cover plate 21 is inserted into the top of the filter box 2. A handle 213 is fixed to the top of the second cover plate 21. Four connecting rods 22 are fixed to the bottom of the second cover plate 21. The bottom of each connecting rod 22 is fixed to the top of the filter screen 221.

[0031] During operation, the second cover plate 21 is lifted by the handle 213, and the second cover plate 21 lifts the filter screen 221 through the connecting rod 22, which facilitates the disassembly and cleaning of the filter screen 221.

[0032] Furthermore, such as Figure 2 As shown, the top of the filter box 2 is fixed with two fastening bolts 211 arranged in a circular pattern. The second cover plate 21 is inserted into the two fastening bolts 211. The top of each fastening bolt 211 is threaded with a rotating block 212.

[0033] During operation, the fastening bolts 211 facilitate the fixing and limiting of the second cover plate 21, and make it easy for the first connecting block 231 and the second connecting block 232 to be quickly connected.

[0034] Furthermore, such as Figure 2 As shown, the top of the filter box 2 is connected to and fixed with an infusion pipe 32, one end of the infusion pipe 32 is connected to and fixed with the bottom of the treatment box 1, and a water pump 31 is fixed to the side wall of the treatment box 1 through a side plate 3. The infusion pipe 32 is installed on the water pump 31. The bottom of the filter box 2 away from the treatment box 1 is connected to and fixed with a drain pipe 4, and a control valve 41 is installed on the drain pipe 4.

[0035] During operation, by setting up the infusion pipe 32 and turning on the water pump 31, the treated waste liquid in the treatment tank 1 is easily pumped into the filter tank 2; then it is filtered through the filter screen 221, and finally the control valve 41 is opened to discharge it through the drain pipe 4.

[0036] Furthermore, such as Figure 2 and Figure 3As shown, the pretreatment mechanism includes a first cover plate 11 installed on the top of the treatment tank 1. A first motor 12 is fixedly connected to the top of the first cover plate 11. The output shaft of the first motor 12 is rotatably connected to the first cover plate 11 via a bearing. A rotating rod 121 is fixedly connected to the output shaft of the first motor 12. A stirring paddle 122 is fixedly connected to the rotating rod 121. A first gear 125 is fixedly connected to the bottom end of the rotating rod 121. A second gear 126 is rotatably connected to the bottom inner wall of the treatment tank 1 via a pin. The first gear 125 meshes with the second gear 126. A rotating seat 123 is rotatably connected to the bottom inner wall of the treatment tank 1. An internal gear ring 127 is fixedly connected to the inner wall of the rotating seat 123. The internal gear ring 127 meshes with the second gear 126. Two stirring rods 124 are fixedly connected to the top of the rotating seat 123. The stirring rods 124 cooperate with the stirring paddle 122.

[0037] During operation, after the treatment agent is input into the treatment tank 1, the first motor 12 needs to be turned on. The first motor 12 drives the rotating rod 121 to rotate via the output shaft, which in turn drives the stirring paddle 122 to rotate for stirring. During the rotation of the rotating rod 121, the rotating rod 121 drives the first gear 125 to rotate clockwise, which in turn drives the second gear 126 to rotate counterclockwise, which in turn drives the gear ring to rotate counterclockwise, which in turn drives the rotating seat 123 to rotate counterclockwise, which in turn drives the stirring rod 124 to rotate counterclockwise. The stirring paddle 122 and the stirring rod 124 rotate in opposite directions to stir the waste liquid, which facilitates the rapid mixing and reaction of the waste liquid and the treatment agent, thereby improving the filtration efficiency.

[0038] Furthermore, such as Figure 2 and Figure 4 As shown, a filter basket 13 is inserted into the top of the first cover plate 11, a spring 135 is fixedly connected to the bottom inner wall of the filter basket 13, a sliding plate 136 is fixedly connected to the top of the spring 135, the sliding plate 136 is slidably connected to the inner wall of the filter basket 13, a sealing plug 131 is inserted into the top of the filter basket 13, and a waste liquid pipe 132 is connected and fixedly connected to the sealing plug 131.

[0039] During operation, electroplating waste liquid enters the filter basket 13 through the waste liquid pipe 132. The filter basket 13 filters out large particulate impurities in the waste liquid. During the process of the waste liquid entering, the gravity of the waste liquid presses the slide plate 136. The slide plate 136 vibrates under the action of the spring 135 and slides on the inner wall of the filter basket 13, which facilitates the scraping of impurities on the inner wall of the filter basket 13 and prevents the filter basket 13 from becoming clogged.

[0040] Furthermore, such as Figure 6As shown, the top of the first cover plate 11 is rotatably connected to three rotating blocks 133 by a pin, and the top of the filter basket 13 is circumferentially fixed with three locking posts 134, which are respectively engaged with the rotating blocks 133.

[0041] During operation, the filter basket 13 is installed by inserting it into the first cover plate 11, and then rotating the rotating block 133, which is locked onto the locking post 134, thus enabling the filter basket 13 to be quickly installed and removed.

[0042] Furthermore, such as Figure 1 As shown, the top of the first cover plate 11 is sequentially connected to and fixed with a first liquid inlet pipe 111, a second liquid inlet pipe 112 and a third liquid inlet pipe 113, and the bottom of the first cover plate 11 is fixedly connected to a pH sensor 14.

[0043] During operation, the top of the first cover plate 11 is sequentially connected to and fixed with a first liquid inlet pipe 111, a second liquid inlet pipe 112, and a third liquid inlet pipe 113. A neutralizing agent is introduced through the first liquid inlet pipe 111 to neutralize the pH of the waste liquid; a flocculant is introduced through the second liquid inlet pipe 112 to flocculate particulate impurities in the second liquid inlet pipe 112; and a reducing agent is introduced through the third liquid inlet pipe 113 to facilitate the reduction of metal ions in the waste liquid. A pH sensor 14 is installed to monitor the pH of the treatment tank 1 in real time and control the amount of neutralizing agent used.

[0044] Working principle: To solve the problem of clogging caused by excessive accumulation of impurities on the surface of activated carbon filter screen 221, during installation, the first connecting block 231 and the second connecting block 232 on filter screen 221 are inserted together. Then, during the filtration process, the second motor 234 needs to be turned on. The output shaft of the second motor 234 drives the rotating shaft 233 to rotate, which in turn drives the second connecting block 232 to rotate. The second connecting block 232 drives the first connecting block 231 to rotate, which in turn drives the scraper 23 to rotate. The rotation of the scraper 23 scrapes away the impurities on the filter screen 221, preventing the mesh of the filter screen 221 from becoming clogged during filtration and affecting the filtration process.

[0045] Neutralizing agent is introduced through the first inlet pipe 111 to neutralize the pH of the waste liquid; flocculant is introduced through the second inlet pipe 112 to flocculate particulate impurities in the second inlet pipe 112; reducing agent is introduced through the third inlet pipe 113 to facilitate the reduction of metal ions in the waste liquid; after the treatment agent is introduced into the treatment tank 1, the first motor 12 needs to be turned on. The first motor 12 drives the rotating rod 121 to rotate through the output shaft, which in turn drives the stirring paddle 122 to rotate for stirring; during the rotation of the rotating rod 121, the first gear 125 rotates clockwise, which in turn drives the second gear 126 to rotate counterclockwise, which in turn drives the gear ring to rotate counterclockwise, which in turn drives the rotating seat 123 to rotate counterclockwise, which in turn drives the stirring rod 124 to rotate counterclockwise. The stirring paddle 122 and the stirring rod 124 rotate in opposite directions to stir the waste liquid, which facilitates rapid mixing and reaction of the waste liquid and the treatment agent, improving the filtration efficiency.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
