[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a wastewater treatment device for electrode paste processing, which has the following beneficial effects:

[0017] 1. The high-pressure air pump connected by the air supply pipe is working. The high-pressure air pump works to allow high-pressure air to enter the interior of the first and second ventilation boxes through the air supply pipe, switch assembly and connecting pipe. The high-pressure air is ejected through multiple jet pipes and blows out the impurities inside the filter plate filter holes and blows them to the bottom of the filter plate, thereby facilitating the cleaning of particulate impurities inside the filter plate filter holes and preventing the filter plate from clogging.

[0018] 2. The first motor drives the first rotating shaft and the sealing plate to rotate. The sealing plate seals the connecting pipe. When the notch rotates to the position of the connecting pipe, the high-pressure air inside the round box enters the interior of the connecting pipe through the notch. This facilitates the intermittent delivery of high-pressure air to the interior of the connecting pipe, the first ventilation box, and multiple second ventilation boxes. This allows high-pressure air to be intermittently ejected from the interior of multiple jet pipes, which facilitates the cleaning of particulate impurities inside the filter plate at intervals and allows wastewater to flow from the bottom to the top of the filter plate.

[0019] 3. The second motor drives the second rotating shaft and cleaning brush to rotate. During the rotation of the cleaning brush, the particulate impurities adsorbed on the bottom of the filter plate are cleaned, so as to avoid the particulate impurities adsorbed on the bottom of the filter plate and causing the filter plate to become blocked.

[0032] Please see Figures 1-8A wastewater treatment device for electrode paste processing includes a filter box 1. A cleaning port 28 is provided on the side of the filter box 1. A sealing seat 29 is fixedly installed on the filter box 1 to seal the cleaning port 28, facilitating the cleaning of impurities on the bottom inside the filter box 1. A filter plate 2 is detachably connected inside the filter box 1. A fixing ring 11 is fixedly connected inside the filter box 1. A connecting ring 12 is fixedly connected to the outside of the filter plate 2. The connecting ring 12 is connected to the fixing ring 11 by multiple first screws 13, facilitating the disassembly and assembly of the filter plate 2. A water inlet pipe 3 is connected to the side of the filter box 1 below the filter plate 2, and a drain pipe 4 is connected to the side of the filter box 1 above the filter plate 2. A cover 5 is fixedly connected to the top of the filter box 1. A sealing gasket 27 is provided between the cover 5 and the filter box 1 to ensure the airtightness between the cover 5 and the filter box 1. A connecting pipe 6 is fixedly connected to the cover 5. One end of the connecting pipe 6 extending into the filter box 1 is connected to a first vent box 7. The bottom end of the first vent box 7 is fixedly connected to multiple second vent boxes 8. The ends of the multiple second vent boxes 8 near the filter plate 2 are all fixedly connected to multiple air jet pipes 9. One-way valves 30 are installed on the multiple air jet pipes 9 to prevent wastewater from entering the interior of the multiple second vent boxes 8. The top end of the connecting pipe 6 is connected to an air supply pipe 10 that is connected to an external high-pressure air pump through a switch assembly.

[0033] Specifically, the high-pressure air pump connected by the air supply pipe 10 operates, causing high-pressure air to enter the interior of the first ventilation box 7 and the second ventilation box 8 through the air supply pipe 10, the switch assembly and the connecting pipe 6. The high-pressure air is ejected through multiple jet pipes 9, blowing out the impurities inside the filter holes of the filter plate 2 and blowing them to the bottom of the filter plate 2, thereby facilitating the cleaning of particulate impurities inside the filter holes of the filter plate 2 and preventing the filter plate 2 from becoming clogged.

[0034] Please see Figure 1 and Figure 7 The switch assembly includes a circular box 14, which is fixedly connected to the connecting pipe 6 and the gas supply pipe 10. A sealing cover 15 is fixedly connected to the top of the circular box 14, and a first motor 16 is fixedly connected to the sealing cover 15. A first rotating shaft 17 is fixedly connected to the output end of the first motor 16. A sealing plate 18 is rotatably connected inside the circular box 14. A notch 19 is provided on the sealing plate 18. The bottom end of the first rotating shaft 17 is fixedly connected to the top end of the sealing plate 18, so that high-pressure gas is intermittently ejected from the inside of multiple jet pipes 9. A support column 20 is fixedly connected to the top end of the box cover 5, and the top end of the support column 20 is fixedly connected to the bottom end of the circular box 14, which facilitates the support and fixation of the circular box 14.

[0035] Specifically, the first motor 16 drives the first rotating shaft 17 and the sealing plate 18 to rotate. The sealing plate 18 seals the connecting pipe 6. When the notch 19 rotates to the position of the connecting pipe 6, the high-pressure air inside the round box 14 enters the interior of the connecting pipe 6 through the notch 19. This facilitates the intermittent delivery of high-pressure air to the interior of the connecting pipe 6, the first ventilation box 7, and multiple second ventilation boxes 8. This allows the high-pressure air to be intermittently ejected from the interior of multiple jet pipes 9, which facilitates the cleaning of particulate impurities inside the filter plate 2 at intervals and allows wastewater to flow from the bottom to the top of the filter plate 2.

[0036] Please see Figures 3-6 A second motor 21 is fixedly connected to the bottom of the filter box 1. A second rotating shaft 22 is fixedly connected to the output end of the second motor 21. A cleaning brush 23 is detachably connected to the top of the second rotating shaft 22. The top of the cleaning brush 23 contacts the bottom of the filter plate 2, which facilitates the removal of particulate impurities adsorbed on the filter plate 2. A square column 24 is fixedly connected to the top of the second rotating shaft 22. A square groove 25 is provided at the bottom of the cleaning brush 23. The square column 24 is inserted into the square groove 25. The cleaning brush 23 is fixedly connected to the square column 24 by a second screw 26, which facilitates the disassembly and assembly of the cleaning brush 23.

[0037] Specifically, the second motor 21 drives the second rotating shaft 22 and the cleaning brush 23 to rotate. During the rotation of the cleaning brush 23, the particulate impurities adsorbed on the bottom of the filter plate 2 are cleaned to prevent the particulate impurities from adsorbing on the bottom of the filter plate 2 and causing the filter plate 2 to become clogged.

[0038] In summary, when using the overall equipment:

[0039] Wastewater generated during electrode paste processing flows into the filter box 1 through the inlet pipe 3. The wastewater then flows through the filter plate 2 to its upper side, where particulate impurities are filtered out. The filtered wastewater is then discharged through the drain pipe 4. Simultaneously, a high-pressure air pump connected to the air supply pipe 10 operates, delivering high-pressure air through the air supply pipe 10 to the interior of the cylindrical box 14. The first motor 16 drives the first rotating shaft 17 and the sealing plate 18 to rotate, sealing the connecting pipe 6 through the sealing plate 18. When the notch 19 rotates to the position of the connecting pipe 6, the interior of the cylindrical box 14... High-pressure air enters the connecting pipe 6, the first vent box 7, and multiple second vent boxes 8 through the notch 19, and is ejected through multiple jet pipes 9, blowing out impurities inside the filter holes of the filter plate 2 and blowing them to the bottom of the filter plate 2. During the rotation of the sealing plate 18, high-pressure air is intermittently ejected from the inside of the multiple jet pipes 9. At the same time, the second motor 21 drives the second rotating shaft 22 and the cleaning brush 23 to rotate. During the rotation of the cleaning brush 23, the particulate impurities adsorbed on the bottom of the filter plate 2 are cleaned, preventing the particulate impurities from adsorbing on the bottom of the filter plate 2 and causing the filter plate 2 to become clogged.
