Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating technology, specifically to a cleaning and filtration device for electrophoretic coating. Background Technology

[0002] Electrophoretic coating is based on electrochemical principles. In an electrophoresis tank, the object to be coated (serving as electrodes) and an electrophoretic paint solution containing charged resin and pigment particles are placed. When a direct current voltage is applied between the electrodes, positively charged particles (cationic electrophoretic paint) move towards the cathode, and negatively charged particles (anionic electrophoretic paint) move towards the anode. These particles lose their charge on the electrode surface and deposit, forming a uniform paint film. For example, in cathodic electrophoretic coating, the object to be coated serves as the cathode. Cationic resin and pigment particles move towards the cathode under the influence of an electric field, undergoing a reduction reaction on the cathode surface and depositing to form a paint film.

[0003] Before electrophoretic coating, the surface of the material to be processed needs to be cleaned. Traditional cleaning equipment is inconvenient to adjust the angle of the material, which can easily lead to incomplete cleaning and waste liquid is difficult to recover, resulting in resource waste.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 A cleaning and filtering device for electrophoretic coating includes a cleaning tank 1, and further includes:

[0029] The liquid supply assembly includes a liquid supply tank 2, a liquid supply pump 3, a connecting pipe 4, a diverter pipe 5, and output heads 6. The cleaning tank 1 has a cleaning chamber on its front side. An annular diverter pipe 5 is installed on the upper side wall of the cleaning chamber. Several sets of output heads 6 are located below the diverter pipe 5, away from the opening of the cleaning chamber. The liquid supply tank 2 is located on the back side of the cleaning tank 1. One end of the liquid supply pump 3 is connected to the liquid supply tank 2, and one end of the connecting pipe 4 is connected to the other end of the liquid supply pump 3. The other end of the connecting pipe 4 passes through the cleaning tank 1 and is connected to the input end of the diverter pipe 5. The liquid supply tank 2 stores cleaning liquid. When the liquid supply pump 3 is started, it generates suction to draw the cleaning liquid out of the liquid supply tank 2. The cleaning liquid is transported through the connecting pipe 4 to the diverter pipe 5 inside the cleaning tank 1. Because the diverter pipe 5 is annularly installed on the upper side wall of the cleaning chamber, the cleaning liquid can be evenly distributed. The output head 6 below the diversion pipe 5 sprays the cleaning fluid into the cleaning chamber to provide the cleaning fluid required for material cleaning. The position design of the output head 6 ensures that the cleaning fluid can cover the material on the hanger.

[0030] The support assembly includes a motor 7, a gear ring 8, gears 9, a turntable 10, a rotating shaft 11, and a mounting component. The output end of the motor 7 passes through the top wall of the cleaning tank 1 and is connected to the turntable 10. Several sets of gears 9 are arranged on the turntable 10. A rotating shaft 11, which passes through the turntable 10, is arranged below the gears 9. A mounting component is also arranged below the rotating shaft 11. Several sets of gear rings 8 that mesh with the gears 9 are also arranged inside the cleaning chamber. The output head 6 is located below the turntable 10. When the motor 7 (preferably a servo motor 7) is powered on, its output end drives the turntable 10 to rotate. The gears 9 on the turntable 10 rotate accordingly, and the gears 9 mesh with the gear rings 8 fixed inside the cleaning chamber. This meshing relationship allows the gears 9 to rotate around their own axis while revolving with the turntable 10. The rotating shaft 11, connected to gear 9, transmits the motion of gear 9. The mounting component is installed below the rotating shaft 11, so the mounting component not only moves in a circular motion with the turntable 10, but also rotates due to the rotation of gear 9. Through this combined motion, the material on the mounting component can change position at multiple angles. The mounting component includes a handle 12, a threaded screw 13, a sliding frame 14, hooks 15, and a mounting frame 16. The sliding frame 14 is located below the rotating shaft 11, and the threaded screw 13 is rotatably mounted below the sliding frame 14. The threaded screw 13 passes through the sliding frame 14 and is connected to the handle 12. The hooks 15 are arranged in two symmetrical sets, with the upper part of the hooks 15 extending into the sliding frame 14 and threadedly connected to the threaded screw 13. The mounting frame 16 for carrying materials is located below the two sets of hooks 15. When the handle 12 is rotated, the threaded screw 13 is rotated. Since the threaded screw 13 is threadedly connected to the hooks 15, and the upper part of the hooks 15 extends into the sliding frame 14, the rotation of the threaded screw 13 will cause the hooks 15 to move along the axial direction of the screw within the sliding frame 14. This facilitates the mounting of the mounting frame 16 with materials of different specifications, ensuring that all surfaces of the materials can fully contact the cleaning liquid during the cleaning process.

[0031] In this embodiment, the lower part of the cleaning tank 1 is further provided with a waste liquid collection assembly, which includes a waste liquid collection tank 17 and a filter plate 18. The waste liquid collection tank 17 with an upper opening is slidably disposed on the bottom wall of the cleaning chamber. Slide grooves are also provided on the left and right sides of the cleaning chamber. The filter plate 18 is slidably connected to the slide grooves. The waste liquid collection tank 17 is disposed below the filter plate 18. The bottom wall of the collection chamber of the waste liquid collection tank 17 is a sloping surface with a higher back side and a lower front side. A drain pipe 19 is also provided on the front of the waste liquid collection tank 17. A switch valve 20 is provided on the drain pipe 19. During the cleaning process, the cleaning liquid containing impurities will flow down from the surface of the material. The waste liquid collection tank 17 on the bottom wall of the cleaning chamber is used to collect this waste liquid. The waste liquid first passes through the filter plate 18. The filter plate 18 is installed in the slide grooves on the left and right sides of the cleaning chamber, which can filter the waste liquid and intercept the impurities in it, preventing them from entering the waste liquid collection tank 17 and re-contaminating the cleaning liquid or clogging the pipe. Waste liquid collection tank 17 collects filtered waste liquid. The bottom wall of its collection chamber is designed as a slope with a higher back side and a lower front side, which facilitates the accumulation of waste liquid towards the drain pipe 19 on the front side under the action of gravity. When it is necessary to transfer the waste liquid, the switch valve 20 on the drain pipe 19 is opened, and the waste liquid can be discharged.

[0032] The hinged door 21 on the front of the cleaning chamber allows operators to easily open the door to hang materials on the hanging rack 16 and remove materials after cleaning. It also facilitates the inspection, cleaning, and maintenance of the interior of the cleaning chamber, especially components such as the filter plate 18.
