[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides the following technical solution: a mesh screen type latex paint impurity filter, including a mixing tank 1, a tank cover 3 on the top of the mixing tank 1, a feed pipe 4 on one side of the top of the tank cover 3, a connecting pipe 14 at the bottom of the mixing tank 1, a second valve 13 installed on the surface of the connecting pipe 14, a connecting shell 9 connected to the bottom of the second valve 13, a filter inner box 10 threadedly connected inside the connecting shell 9, second support rods 15 respectively arranged around the inside of the filter inner box 10, and a motor box 16 connected to one end of the second support rods 15. The filter housing 10 has a second motor inside. The inner wall of the filter housing 10 is provided with support blocks 29. The top of the support blocks 29 is provided with a filter screen 17. The output end of the second motor is connected to a second rotating shaft 23, which passes through the filter screen 17. The surface of the second rotating shaft 23 is provided with connecting rings 26. The surface of the connecting rings 26 is connected with second scrapers 25. The bottom of the second scrapers 25 is located on the surface of the filter screen 17. The bottom of the connecting rings 26 is provided with a movable clamping ring 24, which is located on the top of the filter screen 17.

[0023] In this embodiment: By setting a fixing ring 27 and a second bolt 28, the connecting ring 26 is restricted and fixed, so that the second rotating shaft 23 can drive the connecting ring 26 to rotate, thereby increasing the performance. The movable clamping ring 24 is set to clamp the filter screen 17, thereby increasing the stability of the filter screen 17. At the same time, the connecting ring 26 can move at the top of the movable clamping ring 24, thereby increasing the performance.

[0024] In this embodiment, a first scraper 22 is provided to scrape the inner wall of the mixing tank 1, thereby preventing latex paint from adhering to the inner wall of the mixing tank 1 and affecting the performance.

[0025] In this embodiment, the cover 3 is fixed by setting the threaded hole 21 and the first bolt 2, thereby increasing the stability of the connection.

[0026] In this embodiment, the inner filter box 10 is threadedly connected to the outer casing 9, which facilitates disassembly and assembly to clean and replace the filter screen 17, thereby increasing the convenience of maintenance.

[0027] The working principle and usage process of this utility model are as follows: After installation, when in use, latex paint is fed into the mixing tank 1 through the feed pipe 4, activating the first motor 5. The first motor 5 then drives the mixing plate 18 to rotate via the first rotating shaft 20, causing the mixing plate 18 to stir the paint. A crushing screen 19 is also installed to break up any clumps of latex paint. This combination of stirring plate 18 and crushing screen 19 ensures thorough mixing and prevents sedimentation that could affect subsequent filtration. After mixing, the second valve 13 is opened. Latex paint enters the interior of the filter chamber 10 through the connecting pipe 14, allowing it to be filtered through the filter screen 17 inside the filter chamber 10. The paint passes through two sets of filter screens 17 with different mesh diameters, ensuring better filtration and increasing the effectiveness of impurity removal. Simultaneously, the second motor operates, driving the connecting ring 26 and the second scraper 25 to rotate via the second rotating shaft 23. This causes the second scraper 25 to scrape the surface of the filter screen 17, preventing impurities from clogging the mesh and affecting the filtration effect. All electrical equipment in this device is powered by an external power source.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
