Description

Technical Field

[0001] The utility model relates to the technical field of electrophoresis systems, in particular to an impurity removal device for an electrophoresis coating system. Background Art

[0002] The advantages of electrophoretic coating lie in its water solubility, non-toxicity, and ease of automated control, making it widely used in the automotive, building materials, hardware, and home appliance industries. The basic principle of this technology is to apply an external electric field, causing tiny particles such as pigments and resins suspended in the electrophoretic fluid to migrate in an orderly manner along the direction of the electric field and settle on the surface of the electrode substrate, forming a water-insoluble paint film. This coating method produces a full, uniform, smooth, and even coating. The electrophoretic paint film also outperforms other coating processes in terms of hardness, adhesion, corrosion resistance, impact resistance, and water permeability.

[0003] However, we discovered a problem when using an electrophoretic coating system on automotive parts. Impurities may remain after production, and these impurities can be introduced into the electrophoretic fluid, causing contamination during use. This can affect the product's coloring and, in turn, the coating quality of the auto parts. To address this issue, we proposed an impurity removal device for the electrophoretic coating system. Summary of the Invention

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figures 1-6 A debris removal device for an electrophoretic coating system includes an electrophoretic pool 1. A debris removal mechanism is installed on one side of the electrophoretic pool 1. The debris removal mechanism includes a hollow shell 2. A filter plate 3 is arranged in the shell 2. A liquid inlet pipe 4 is installed on the top of the shell 2 on one side of the filter plate 3. A liquid return pipe 5 is installed on the bottom of the shell 2 on the other side of the filter plate 3. A circulating pump 6 is installed on the liquid return pipe 5.

[0030] Please refer again Figure 2 A top cover 7 is provided on the top of the shell 2, the top of the top cover 7 is connected to a limiting mechanism, and a rubber plug 8 matching the inner wall of the shell 2 is provided on the bottom of the top cover 7, and the rubber plug 8 plays a sealing role.

[0031] By setting a limiting mechanism, the filter plate 3 can be easily removed. Specifically, the limiting mechanism includes a column 9 arranged on one side of the upper end of the shell 2, and a cross bar 10 is threadedly mounted on the column 9. A through hole 11 is opened at the end of the cross bar 10 away from the column 9, and a stop block 12 is arranged in the through hole 11.

[0032] Please refer again Figure 5 and Figure 6 The cross section of the stopper 12 is I-shaped. The stopper 12 includes a vertical portion and horizontal portions located at the upper and lower ends of the vertical portion. A spring 13 is mounted on the vertical portion. The spring 13 is located between the cross bar 10 and the horizontal portion at the lower end of the vertical portion. By lifting the stopper 12 upward and then rotating the cross bar 10, the limit on the top cover 7 is released.

[0033] In this embodiment, the housing 2 is connected to the electrophoresis pool 1 via a liquid inlet pipe 4, and the housing 2 is connected to the electrophoresis pool 1 via a liquid return pipe 5. The connection point between the liquid inlet pipe 4 and the electrophoresis pool 1 is close to the bottom of the electrophoresis pool 1, and the connection point between the liquid return pipe 5 and the electrophoresis pool 1 is close to the bottom of the electrophoresis pool 1. Under the action of the circulating pump 6, the electrophoresis liquid is drawn out from the liquid inlet pipe 4, flows through the housing 2, and then re-enters the electrophoresis pool 1 through the liquid return pipe 5.

[0034] Please refer again Figure 3 Two ridges 14 are symmetrically arranged on the inner wall of the shell 2. A groove 15 matching the filter plate 3 is opened on the ridge 14. The groove 15 passes through the ridge 14 in the up and down direction, making it convenient to extract or put in the filter plate 3.

[0035] Specifically, the height of the ridge 14 is equal to that of the filter plate 3 and is less than that of the housing 2 . The rubber stopper 8 is located between the ridge 14 and the top cover 7 to prevent leakage of the electrophoresis liquid.

[0036] In this embodiment, after removing the top cover 7 and the rubber stopper 8, in order to further facilitate the extraction of the filter plate 3, handles 16 are provided on both sides of the upper end of the filter plate 3; in addition, a solenoid valve 17 is provided at one end of the liquid inlet pipe 4 close to the electrophoresis tank 1. By opening the solenoid valve 17, the electrophoresis liquid is regularly cleaned of impurities.

[0037] The working principle of this utility model is:

[0038] When in use, the solenoid valve 17 and the circulation pump 6 are opened, and the electrophoresis liquid that needs to be filtered and impurities removed inside the electrophoresis pool 1 is pumped from the liquid inlet pipe 4 into the housing 2 through the circulation pump 6, so that the electrophoresis liquid can be filtered and impurities removed under the filtering action of the filter plate 3. The electrophoresis liquid after impurities removal flows back to the electrophoresis pool 1 through the return pipe 5, and has the function of recycling.

[0039] When the filter plate 3 needs to be taken out for replacement, the stopper 12 is lifted upward and the cross bar 10 is rotated to release the limit on the top cover 7, making it convenient for the staff to take out the filter plate 3 for replacement. After the new filter plate 3 is replaced, the stopper 12 is also lifted upward and the cross bar 10 is rotated in the opposite direction. After the stopper 12 at one end of the cross bar 10 is above the top cover 7, the stopper 12 is released. At this time, under the elastic force of the spring 13, the stopper 12 is pressed against the top cover 7 again, thereby pressing the rubber plug 8, and the replacement process of the filter plate 3 is completed.
