[0002] Latex paint is a water-based paint formulated with a synthetic resin emulsion as the base material, added with pigments, fillers and various additives. It is widely used in environmentally friendly coatings for housing construction and is widely used because of its advantages such as rapid film formation, shortened construction period, saving construction costs, excellent air permeability, environmental protection and no peculiar smell, and good washability.
[0003] The existing filtering devices for latex paint in the production process have the following deficiencies: Since latex paint is relatively viscous and has poor fluidity, when latex paint enters the equipment, if it is to pass through the sieve by its own fluidity for filtration, it requires a lot of time, resulting in low filtration efficiency. When latex paint solidifies during filtration, it is easy to adhere to the filter screen, and thus it is easy to cause blockage of the filtering device. Therefore, we propose a filtering device for latex paint production to solve the above problems. Summary of the Utility Model

In addition, the air pump 15 conveys air into the latex paint filtering cylinder 5, so that the upper side of the latex paint inside the latex paint filtering cylinder 5 is subjected to gas pressure.

Then, under the action of the high-pressure water flow at the spray nozzles 22, the inner wall of the latex paint filtering cylinder 5 and the filter screen 10 are flushed to prevent the latex paint from solidifying and caking.
[0032] In this mode, a low-speed motor 2 is fixedly installed on the side of the bracket 1, a rotating shaft 6 is rotatably installed inside the bracket 1, the output end of the low-speed motor 2 is fixedly connected to the rotating shaft 6, and the inner end of the rotating shaft 6 is fixedly connected to the outer wall of the latex paint filtering cylinder 5.
[0033] Through the above settings, when the low-speed motor 2 rotates, it can drive the latex paint filtering cylinder 5 to rotate through the rotating shaft 6, and then the latex paint filtering cylinder 5 is flipped for the needs of cleaning work.

[0042] Through the above setting, the setting of a number of suspension rings 24 strengthens the connection strength of the annular pipe 21.
[0043] The working principle of a filtering device for latex paint production provided by the present utility model is as follows:
[0044] When in use, when the device is filtering, the top cover 13 is displaced upward, and the latex paint to be filtered is added to the latex paint filter cartridge 5 from the feeding port 17. Subsequently, the second solenoid valve in the feeding port 17 is closed, and the starting motor 14 is started to drive the stirring blade 19 to rotate to stir the latex paint and accelerate the fluidity of the latex paint. At the same time, the air pump 15 can transport air into the latex paint filter cartridge 5, so that the upper side of the latex paint inside the latex paint filter cartridge 5 is subjected to the effect of gas pressure, and then under the dual effects of accelerating fluidity and air pressure, the filtering effect of the latex paint is accelerated. The filtered latex paint flows onto the bottom cover 11 and flows into the receiving tank 3 through the discharge port 12 of the bottom cover 11. When the filtering is completed, the filtered latex paint in the receiving tank 3 is transferred and cleaned. The water pump 16 is started to transport high-pressure water to the nozzle 22 through the through pipe 20 and the ring pipe 21. The high-pressure water sprayed by the nozzle 22 hits the inner wall of the latex paint filter cartridge 5 and After the filter screen 10 has performed a flushing effect, the residual latex paint on the lower side of the filter screen 10 flows into the receiving tank 3 from the discharge port 12 with the water flow. Subsequently, the first solenoid valve inside the discharge port 12 is closed, and the electric telescopic rod 7 is started to retract, so that the output end of the electric telescopic rod 7 exits the limiting hole 9 on the side of the latex paint filter cartridge 5. Later, the low-speed motor 2 is started to drive the entire latex paint filter cartridge 5 to rotate 180 degrees, so that the top cover 13 is at the bottom, and then the electric telescopic rod 7 is started to extend, and its output end is inserted into the limiting hole 9 on the side wall of the latex paint filter cartridge 5. Subsequently, the third solenoid valve inside the air inlet pipe 23 is closed, and then the water pump 16 is started to flush the inside of the latex paint filter cartridge 5, and then the latex paint residue on the lower side of the filter screen 10 and the filter residue that failed to pass through the filter screen 10 follow the water flow from the feeding port 17 to the receiving tank 3 on the lower side. At this point, the residue cleaned inside the latex paint filter cartridge 5 is discharged to the outside of the latex paint filter cartridge 5.
