A through hole 6 is opened on the upper surface of the filter screen plate 5. The through hole 6 is located below the center of the filter screen box 4. A connecting mechanism is provided on the base 1. Paint is input into the pressurizing part 2. The paint flows into the interior of the base 1 and then pressurizes the interior of the base 1 to increase the filtration speed of the paint. The paint is filtered when it passes through the filter screen plate 5 and the filter screen box 4. The filter screen box 4 increases the contact area during paint filtration, thereby increasing the filtration speed of the paint. After being filtered by the filter screen box 4, the paint passes through the filter screen plate 5 through the through hole 6. The paint is not filtered repeatedly. The filtered paint is discharged from the outlet 20.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the connecting mechanism includes an upper mounting plate 7 fixedly installed on the side of the pressure unit 2 and a lower mounting plate 8 fixedly installed on the side of the base 1. Both the upper mounting plate 7 and the lower mounting plate 8 have mounting holes 9 arranged in a circular array on their surfaces. Connecting bolts 10 are installed inside the mounting holes 9, and a fixing nut 11 is threaded onto one end of each connecting bolt 10. Sealing grooves 12 are provided on the surfaces of both the base 1 and the pressure unit 2. A convex washer 13 is inserted into the inner wall of the sealing groove 12, and a sealing ring 14 is fixedly connected to the surface of the convex washer 13. When cleaning the filter screen 5 and the filter box 4, the fixing nut 11 on the connecting bolt 10 is removed, and then the connecting bolt 10 is removed from the mounting hole 9. The pressure unit 2 is then removed, and the filter screen 5 and the filter box 4 are cleaned. The filter box 4 is exposed, facilitating the cleaning of the filter plate 5 and the filter box 4. When installing the pressure unit 2, first install the sealing ring 14 on the base 1 through the cooperation of the convex washer 13 and the sealing groove 12. Then install the pressure unit 2 on top of the base 1, align the mounting holes 9 on the upper mounting plate 7 and the lower mounting plate 8, and make the sealing groove 12 on the pressure unit 2 cooperate with the convex washer 13. Insert the connecting bolt 10 into the mounting hole 9 from below the lower mounting plate 8, and let it pass through the mounting hole 9 on the upper mounting plate 7. Then tighten the fixing nut 11 on the connecting bolt 10, so that the base 1 and the pressure unit 2 are tightened, thereby making the base 1 and the pressure unit 2 tightly cooperate through the sealing ring 14, improving the sealing performance at the connection between the base 1 and the pressure unit 2.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, a support plate 15 is fixedly connected to the upper surface of the pressurizing part 2, a mounting base 16 is fixedly connected to the upper surface of the support plate 15, a hydraulic rod 17 is fixedly connected to the lower surface of the mounting base 16, and a pressurizing seat 18 is fixedly connected to the output end of the hydraulic rod 17. The inner wall of the pressurizing part 2 is slidably connected to the pressurizing seat 18. An input pipe 22 is fixedly connected to the side of the pressurizing part 2. A cleaning ring 19 is embedded in the upper surface of the pressurizing part 2, and the inner wall of the cleaning ring 19 is slidably connected to the pressurizing seat 18. After the paint is input into the pressurizing part 2 through the input pipe 22, the hydraulic rod 17 drives the pressurizing seat 18 to move downward. The side arm of the pressurizing seat 18 blocks the input pipe 22, pushing the paint into the filter screen plate 5 and the filter screen box 4, increasing the filtration speed of the paint. Then the pressurizing seat 18 is reset, and the paint is input again to repeat the work. During the movement of the pressurizing seat 18, the cleaning ring 19 cleans the surface of the pressurizing seat 18, making it difficult for the pressurizing seat 18 to bring dust into the paint.

[0029] In this embodiment, as Figures 1-6 As shown, the working principle of the paint impurity filtration device provided in this embodiment is as follows:

[0030] Paint is fed into the pressurizing section 2 through the input pipe 22. The paint flows into the base 1. The hydraulic rod 17 drives the pressurizing seat 18 to move downward. The side arm of the pressurizing seat 18 blocks the input pipe 22, pushing the paint into the filter screen plate 5 and the filter box 4. The paint is pressurized, which increases the filtration speed. The paint is filtered as it passes through the filter screen plate 5 and the filter box 4. The filter box 4 increases the contact area of ​​the paint during filtration, thereby increasing the filtration speed. After being filtered by the filter box 4, the paint passes through the filter screen plate 5 through the through hole 6. The paint is not filtered repeatedly. The filtered paint is discharged from the outlet 20.
