Description

Technical Field

[0001] This utility model belongs to the field of electrophoretic coating technology, and specifically relates to an electrophoretic tank liquid filtration device. Background Technology

[0002] Electrophoretic coating processes metals using an electrophoretic solution in an electrophoretic tank. The electrophoretic solution reacts with the metal surface, thereby improving the metal's corrosion resistance.

[0003] Currently, Chinese utility model patent CN213172640U discloses a temperature-controlled circulating filtration electrophoresis tank for electrophoretic solution. In existing electrophoresis equipment, impurities adhering to the surface of mechanical workpieces can fall into the electrophoresis tank during the coating process, causing turbidity in the electrophoretic solution and reducing the coating effect on the workpiece surface. Current methods involve draining the electrophoretic solution from the tank and filtering it during the discharge process. However, this filtration method results in slow discharge and low filtration efficiency. Furthermore, impurities within the electrophoretic solution can clog the filter screen, requiring regular cleaning to maintain filtration effectiveness, thus limiting its overall practicality. Utility Model Content

[0004] The purpose of this invention is to provide a filtration device for electrophoresis tank liquid. Its advantage is that it facilitates rapid filtration of the electrophoresis liquid inside the electrophoresis tank and accumulates the filtered impurities together for easy subsequent cleaning.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an electrophoresis tank slurry filtration device, comprising an electrophoresis tank, a sliding plate slidably connected inside the electrophoresis tank, a filter screen bolted inside the sliding plate, fixing rings welded to both sides of the top of the sliding plate, a motor bolted to one side of the electrophoresis tank, a transmission rod rotatably connected to the output end of the motor, a winding wheel fixedly sleeved on both sides of the surface of the transmission rod, a lifting rope fixedly wound around the surface of the winding wheel, and the end of the lifting rope away from the winding wheel being fixedly connected to the fixing ring.

[0006] Using the above technical solution, the motor drives the winding wheel to wind the lifting rope to the surface, allowing the rope to pull the sliding plate upwards inside the electrophoresis tank. This enables the filter screen to filter the electrophoresis solution inside the tank. This filtration method is not only fast but also prevents the filter screen from clogging, effectively improving the filtration efficiency of the electrophoresis solution. By sliding a scraper on top of the filter screen, the scraper pushes the impurities filtered out from the top of the filter screen to one side inside the sliding plate. This facilitates subsequent cleaning of the impurities filtered out from the top of the filter screen, improving practicality.

[0007] The present invention is further configured such that: a scraper is slidably connected to the top of the filter screen, and a sliding ring is welded to both ends of the scraper; a positioning rod welded to the sliding plate is slidably connected through the inside of the sliding ring; and a compression spring is sleeved on one end of the surface of the positioning rod and respectively bolted to the sliding plate and the sliding ring.

[0008] By adopting the above technical solution, the impurities filtered out from the top of the filter screen can be concentrated and pushed to one side inside the sliding plate, which facilitates the subsequent cleaning of the impurities filtered out from the top of the filter screen.

[0009] The present invention is further configured such that a drain valve is fixedly connected to one side of the bottom of the electrophoresis tank.

[0010] By adopting the above technical solution, the electrophoresis solution inside the electrophoresis tank can be drained, making it convenient to add new electrophoresis solution.

[0011] The present invention is further configured such that: both sides of the top of the electrophoresis tank are bolted with fixing rods, and the surface of the fixing rods is rotatably connected with rotating wheels that cooperate with the lifting rope.

[0012] The above technical solution is used to support the sliding of the lifting rope, thereby reducing the frictional force of the lifting rope sliding inside the electrophoresis tank.

[0013] The present invention is further configured such that a sealing ring is fixedly sleeved on the surface of the sliding plate and slidably connected to the inner wall of the electrophoresis tank.

[0014] By adopting the above technical solution, the sealing performance between the sliding plate and the electrophoresis tank during sliding is improved, thus ensuring the filtration effect of the electrophoresis solution.

[0015] The present invention is further configured such that a ventilation mesh plate for use with the motor is bolted to the bottom of the electrophoresis tank near the motor.

[0016] By adopting the above technical solution, the motor can be ventilated and cooled, thereby improving the motor's working stability.

[0017] The present invention is further configured such that: both ends of the surface of the winding wheel are fixedly sleeved with limiting discs that cooperate with the lifting rope.

[0018] By adopting the above technical solution, the two ends of the surface of the take-up reel are limited so that the lifting rope can be evenly wound on the surface of the take-up reel.

[0019] The present invention is further configured such that the surfaces of the filter screen, the lifting rope, and the compression spring are all coated with a corrosion-resistant coating.

[0020] By adopting the above technical solution, excessive corrosion by the electrophoresis solution inside the electrophoresis tank can be avoided, thus improving the service life.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. By turning on the motor and driving the winding wheel, the lifting rope is wound up to the surface, allowing the lifting rope to pull the sliding plate upwards inside the electrophoresis tank. This enables the filter screen to filter the electrophoresis solution inside the tank. This filtration method is not only fast, but also prevents the filter screen from clogging easily, effectively improving the filtration efficiency of the electrophoresis solution.

[0023] 2. By sliding the scraper on top of the filter screen, the scraper pushes the impurities filtered out from the top of the filter screen to one side of the sliding plate. This facilitates subsequent cleaning of the impurities filtered out from the top of the filter screen, improving its practicality. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 4An electrophoresis tank liquid filtration device includes an electrophoresis tank 1. A sliding plate 2 is slidably connected inside the electrophoresis tank 1. A filter screen 3 is bolted inside the sliding plate 2. Fixing rings 4 are welded to both sides of the top of the sliding plate 2. A motor 6 is bolted to one side of the electrophoresis tank 1. A transmission rod 7, rotatably connected to the electrophoresis tank 1, is bolted to the output end of the motor 6. Rewinding wheels 8 are fixedly sleeved on both sides of the surface of the transmission rod 7. A lifting rope 5 is fixedly wound around the surface of the rewinding wheels 8. The end of the lifting rope 5 away from the rewinding wheels 8 is fixedly connected to the fixing rings 4. By turning on the motor 6, the rewinding wheels 8 are driven to wind the lifting rope 5 to the surface, allowing the lifting rope 5 to pull the sliding plate 2 upwards inside the electrophoresis tank 1, thereby enabling the filter screen 3 to filter the electrophoresis liquid inside the electrophoresis tank 1. This filtration method is not only fast, but also prevents the filter screen from clogging easily, effectively improving the filtration efficiency of the electrophoresis liquid.

[0032] refer to Figure 1 , Figure 2 Both sides of the top of the electrophoresis tank 1 are bolted with fixing rods 14, and rotating wheels 15 that cooperate with the lifting rope 5 are rotatably connected to the surface of the fixing rods 14. These wheels are used to support the sliding of the lifting rope 5, thereby reducing the friction of the lifting rope 5 sliding inside the electrophoresis tank 1.

[0033] refer to Figure 2 , Figure 3 A sealing ring 16 is fixedly sleeved on the surface of the sliding plate 2 and slidably connected to the inner wall of the electrophoresis tank 1. This improves the sealing performance between the sliding plate 2 and the electrophoresis tank 1 during sliding, ensuring the filtration effect of the electrophoresis solution.

[0034] refer to Figure 2 A ventilation mesh plate 17, which works in conjunction with the motor 6, is bolted to the bottom of the electrophoresis tank 1 on the side near the motor 6. This allows for ventilation and heat dissipation of the motor 6, improving its operational stability.

[0035] refer to Figure 4 Both ends of the surface of the take-up reel 8 are fixedly fitted with limiting discs 18 that work in conjunction with the lifting rope 5. These limiting discs restrict the movement of both ends of the surface of the take-up reel 8, allowing the lifting rope 5 to be wound evenly around the surface of the take-up reel 8.

[0036] Brief description of the operation: By turning on the motor 6, the winding wheel 8 on the surface of the transmission rod 7 rotates, causing the winding wheel 8 to wind the lifting rope 5 onto the surface. Then, by pulling the fixing ring 4 with the lifting rope 5, the sliding plate 2 slides upward inside the electrophoresis tank 1. During the upward movement of the sliding plate 2, the filter screen 3 can uniformly filter the electrophoresis solution inside the electrophoresis tank 1, causing impurities to be filtered out to the top of the filter screen 3, and then moved to the top of the electrophoresis tank 1 by the sliding plate 2.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 2 , Figure 3 The electrophoresis tank effluent filtration device includes a scraper 9 slidably connected to the top of the filter screen 3. Sliding rings 10 are welded to both ends of the scraper 9. A positioning rod 11, welded to a sliding plate 2, is slidably connected through the interior of each sliding ring 10. A compression spring 12, bolted to both the sliding plate 2 and the sliding ring 10, is fitted onto one end of the positioning rod 11. By sliding the scraper 9 on top of the filter screen 3, the scraper 9 concentrates and pushes the impurities filtered from the top of the filter screen 3 to one side inside the sliding plate 2. This facilitates subsequent cleaning of the impurities filtered from the top of the filter screen 3, improving its practicality.

[0039] refer to Figure 1 A drain valve 13 is fixedly connected to one side of the bottom of the electrophoresis tank 1. This allows the electrophoresis solution inside the electrophoresis tank 1 to be drained, making it convenient to add new electrophoresis solution.

[0040] refer to Figure 2 , Figure 3 The surfaces of the filter screen 3, the lifting rope 5, and the compression spring 12 are all coated with a corrosion-resistant coating. This prevents excessive corrosion from the electrophoresis solution inside the electrophoresis tank 1 and extends their service life.

[0041] Brief description of usage: By sliding the scraper 9 on top of the filter screen 3, the scraper 9 causes the sliding ring 10 to slide on the surface of the positioning rod 11, limiting the scraper 9. This allows the scraper 9 to concentrate and push the impurities filtered from the top of the filter screen 3 to one side inside the sliding plate 2. Simultaneously, when the scraper 9 is released, the scraper 9 can be reset by the rebound force of the compression spring 12 pushing the sliding ring 10 to slide on the surface of the positioning rod 11, thus resetting to the other side.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
