Description

Technical Field

[0001] The utility model relates to the technical field of electrophoresis tanks, in particular to an electrophoresis tank for electrophoresis coating. Background Art

[0002] Electrophoresis coating is a special coating method in which the conductive object to be coated is immersed in an electrophoresis coating tank filled with water-diluted and relatively low-concentration electrophoresis coating as the anode, and a corresponding cathode is arranged in the tank. After direct current is applied between the two electrodes for a period of time, a uniform, fine and water-insoluble coating film is deposited on the surface of the object to be coated. During electrophoresis coating, an electrophoresis tank is required, and the accessories are placed in the electrophoresis tank for coating treatment. However, after electrophoresis coating, some impurities will remain in the electrophoresis solution, and the current electrophoresis tank is not convenient for filtering the impurities in the electrophoresis solution, which is likely to affect the quality of electrophoresis coating.

[0003] Therefore, those skilled in the art have proposed an electrophoresis tank for electrophoresis coating to solve the problems raised in the above background. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electrophoresis tank for electrophoresis coating to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An electrophoresis tank for electrophoresis coating, comprising an electrophoresis tank; brackets are arranged on both sides of the electrophoresis tank, two symmetrically distributed cylinders are arranged on the top of the brackets, a suspension member is arranged at the bottom of the cylinders for placing the accessories to be electrophoresed, the suspension member is connected with a movable plate, the outer wall of the movable plate is attached to the inner wall of the electrophoresis tank, a plurality of symmetrically distributed liquid inlet openings are arranged on the movable plate, and a movable closing member is arranged at the liquid inlet openings for opening and closing the liquid inlet openings. Drainage openings are arranged on both sides of the top of the electrophoresis tank, the drainage openings are connected with a filter box, a filter plate is arranged in the filter box, a plurality of equally spaced diversion pipes are arranged at the bottom of the filter box, and a circulation opening connected with the diversion pipes is arranged on the inner wall of the electrophoresis tank.

[0007] As a further scheme of the utility model: a liquid injection pipe and a liquid discharge pipe are arranged on the outer wall of the electrophoresis tank.

[0008] As a further scheme of the utility model: the height of the liquid injection pipe is higher than that of the liquid discharge pipe.

[0009] As a further scheme of the utility model: the suspension member includes a mounting plate installed at the bottom of the cylinder, a plurality of equally spaced placement racks are installed on both sides of the mounting plate, and the bottom of the mounting plate is connected with the movable plate.

[0010] As a further solution of the present utility model: The movable closing member includes a sealing plate rotatably arranged on the movable plate and close to one side of the liquid inlet, and a spring is arranged on the sealing plate, and the spring is connected to the inner wall of the liquid inlet.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, by placing the fittings on the hanging member and starting the cylinder, the cylinder extends to drive the hanging member to descend. When the hanging member descends, it will drive the movable plate to descend. When the movable plate descends, it will open the movable closing member through the electrophoresis liquid in the electrophoresis tank, so that the liquid inlet is opened, and the electrophoresis liquid enters above the movable plate and performs electrophoresis coating on the fittings placed on the hanging member. When the electrophoresis coating is completed, the cylinder is started in the reverse direction to drive the hanging member to rise. When the hanging member rises, it will drive the movable plate to rise. At this time, due to the existence of the electrophoresis liquid above the movable plate, the movable closing member will keep blocking the liquid inlet, thereby driving the electrophoresis liquid above the movable plate to rise and move to the position of the drain port. The electrophoresis liquid above the movable plate will enter the filter tank through the drain port, filter the impurities in the electrophoresis liquid through the filter plate, and re-enter the electrophoresis tank below the movable plate through the diversion pipe and the circulation port, so as to avoid the influence of the residual impurities in the electrophoresis liquid on the subsequent electrophoresis coating effect after the electrophoresis coating is completed. Moreover, through the lifting of the movable plate, the electrophoresis liquid can also flow, thereby avoiding the precipitation of the electrophoresis liquid. Description of the Drawings

[0017] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0018] Please refer to Figures 1-4, An electrophoresis tank for electrophoretic coating, including an electrophoresis tank 1; brackets 4 are arranged on both sides of the electrophoresis tank 1, two symmetrically distributed cylinders 5 are arranged on the top of the brackets 4, and a suspension member is arranged at the bottom of the cylinder 5 for placing accessories to be electrophoresed. The suspension member is connected with a movable plate 8, the outer wall of the movable plate 8 fits against the inner wall of the electrophoresis tank 1, a plurality of symmetrically distributed liquid inlets 9 are arranged on the movable plate 8, and a movable closing member is arranged at the liquid inlet 9 for opening and closing the liquid inlet 9. Drainage ports 12 are opened on both sides of the top of the electrophoresis tank 1, the drainage ports 12 are connected with a filter tank 13, a filter plate 14 is arranged in the filter tank 13, and a plurality of equally spaced diversion pipes 15 are arranged at the bottom of the filter tank 13. A circulation port 16 connected to the diversion pipe 15 is opened on the inner wall of the electrophoresis tank 1.

[0019] By placing the accessories on the suspension member and starting the cylinder 5, the cylinder 5 extends to drive the suspension member to descend. When the suspension member descends, it will drive the movable plate 8 to descend. When the movable plate 8 descends, it will open the movable closing member through the electrophoresis liquid in the electrophoresis tank 1, so that the liquid inlet 9 is opened, enabling the electrophoresis liquid to enter above the movable plate 8 and electrophoretically coat the accessories placed on the suspension member. And when the cylinder 5 stops extending, the movable closing member will close the liquid inlet 9. When the electrophoretic coating is completed, the cylinder 5 is started in reverse to drive the suspension member to rise. When the suspension member rises, it will drive the movable plate 8 to rise. At this time, due to the presence of the electrophoresis liquid above the movable plate 8, the movable closing member will keep the liquid inlet 9 blocked, thereby driving the electrophoresis liquid above the movable plate 8 to rise and move to the position of the drainage port 12. The electrophoresis liquid above the movable plate 8 will enter the filter tank 13 from the drainage port 12, thereby filtering the impurities in the electrophoresis liquid and re-entering the electrophoresis tank 1 below the movable plate 8 through the diversion pipe 15 and the circulation port 16. This can avoid the influence of the residual impurities in the electrophoresis liquid after the electrophoretic coating on the subsequent electrophoretic coating effect. And through the lifting of the movable plate 8, the electrophoresis liquid can also be made to flow, thereby avoiding precipitation of the electrophoresis liquid.

[0020] A liquid injection pipe 2 and a liquid discharge pipe 3 are arranged on the outer wall of the electrophoresis tank 1. The height of the liquid injection pipe 2 is higher than that of the liquid discharge pipe 3. Valves are arranged in the liquid injection pipe 2 and the liquid discharge pipe 3, and the liquid injection pipe 2 and the liquid discharge pipe 3 are opened and closed by valve control for injecting or discharging the electrophoresis liquid.

[0021] The suspension member includes a mounting plate 6 installed at the bottom of the cylinder 5. A plurality of equally spaced placing racks 7 are installed on both sides of the mounting plate 6. The bottom of the mounting plate 6 is connected with the movable plate 8. During use, the accessories are fixed on the placing racks 7. When the cylinder 5 extends to drive the mounting plate 6 to descend, the accessories on the placing racks 7 can be driven to descend synchronously to the bottom of the electrophoresis tank 1.

[0022] The movable closing member includes a sealing plate 10 rotatably arranged on the movable plate 8 and close to one side of the liquid inlet 9. A spring 11 is arranged on the sealing plate 10 and connected to the inner wall of the liquid inlet 9. When the cylinder 5 extends to drive the mounting plate 6 to descend, it will also drive the movable plate 8 to descend. When the movable plate 8 descends, it will squeeze the electrophoresis liquid at the bottom of the electrophoresis tank 1. The sealing plate 10 is opened by the generated squeezing force, so that the electrophoresis liquid at the bottom of the electrophoresis tank 1 enters above the movable plate 8 from the liquid inlet 9. When the cylinder 5 stops extending, the sealing plate 10 will block the liquid inlet 9 under the action of the spring 11. The electrophoresis liquid above the movable plate 8 is used for electrophoretic coating of the fittings on the placement rack 7. After the electrophoretic coating is completed, the cylinder 5 is started in reverse to drive the mounting plate 6 to rise, driving the movable plate 8 to rise. Due to the existence of the electrophoresis liquid above the movable plate 8, the sealing plate 10 is pressed on the surface of the movable plate 8 to block the liquid inlet 9. The electrophoresis liquid above the movable plate 8 will rise as the movable plate 8 rises until the movable plate 8 moves to the liquid discharge port 12, and the electrophoresis liquid will enter the filter box 13 to filter impurities through the filter plate 14.

[0023] The working principle of the present utility model is as follows: Place the fitting on the hanging member, start the cylinder 5, the cylinder 5 extends to drive the hanging member to descend. When the hanging member descends, it will drive the movable plate 8 to descend. When the movable plate 8 descends, it will open the movable closing member through the electrophoresis liquid in the electrophoresis tank 1, so that the liquid inlet 9 is opened, and the electrophoresis liquid enters above the movable plate 8 and performs electrophoretic coating on the fittings placed on the hanging member. After the electrophoretic coating is completed, the cylinder 5 is started in reverse to drive the hanging member to rise. When the hanging member rises, it will drive the movable plate 8 to rise. At this time, due to the existence of the electrophoresis liquid above the movable plate 8, the movable closing member will keep blocking the liquid inlet 9, thereby driving the electrophoresis liquid above the movable plate 8 to rise and move to the position of the liquid discharge port 12. The electrophoresis liquid above the movable plate 8 will enter the filter box 13 from the liquid discharge port 12, filter the impurities in the electrophoresis liquid through the filter plate 14, and re-enter the electrophoresis tank 1 below the movable plate 8 through the diversion pipe 15 and the circulation port 16, so as to avoid the influence of the residual impurities in the electrophoresis liquid after the electrophoretic coating on the subsequent electrophoretic coating effect. Moreover, through the lifting of the movable plate 8, the electrophoresis liquid can also flow, thereby avoiding precipitation of the electrophoresis liquid.
