[0002] In the field of paint production and processing, different paints have different viscosities. The higher the viscosity of the paint, the worse its fluidity. Because of the high viscosity and weak fluidity of such paints, the resistance during flow is large, resulting in extremely slow flow speed.

A first piston plate 12 is fixedly installed at the output end of the first reciprocating push rod 11. The outer wall of the first piston plate 12 is slidably connected to the inner wall of the pressure sleeve 1. The first reciprocating push rod 11 drives the first piston plate 12 to move up and down reciprocally inside the pressure sleeve 1, thereby generating pressure to push the coating to flow. A pressure gauge 24 is connected to the bottom side outer wall of the pressure sleeve 1 through an opening to monitor the pressure inside the pressure sleeve 1. Example 3

[0022] Based on Embodiment 1, the bottom center of the feed sleeve 2 is connected to the guide pipe 3 through an opening. The other end of the guide pipe 3 is connected to the top side of the filter sleeve 7. The bottom side of the feed sleeve 2 is connected to the feed pipe 4 through an opening. A first one-way valve 5 is installed on the guide pipe 3, and a second one-way valve 6 is installed on the feed pipe 4. The first one-way valve 5 and the second one-way valve 6 control the flow direction of the coating in the guide pipe 3 and the feed pipe 4 respectively to prevent the coating from flowing back. A limiting ring 16 is fixedly installed on the inner wall of the feed sleeve 2. The limiting ring 16 is located directly above the connection between the feed pipe 4 and the feed sleeve 2. Example 4

[0023] Based on Embodiment 1, a second fixing ring 13 is fixedly installed at the top center of the feed sleeve 2 via a bracket. A vertically downward second reciprocating push rod 14 is fixedly installed on the inner wall of the second fixing ring 13. A second piston plate 15 is fixedly installed at the output end of the second reciprocating push rod 14. The outer wall of the second piston plate 15 is slidably connected to the inner wall of the feed sleeve 2. The second piston plate 15 is driven to move up and down reciprocally within the feed sleeve 2 by the second reciprocating push rod 14. A third fixing ring 22 is fixedly installed on the outer wall of the filter sleeve 7. Equally spaced support legs 23 are fixedly installed on the outer wall of the third fixing ring 22. The outer wall of the support legs 23 is fixedly connected to the outer wall of the receiving hopper 20 via a bracket.

[0024] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-4In use, this invention first connects the feed pipe 4 to the paint tank, then activates the second reciprocating push rod 14 at the top of the feed sleeve 2, causing its output end to drive the second piston plate 15 upward. At this time, the internal space of the feed sleeve 2 gradually increases, and the pressure decreases, creating a pressure difference between the inside and outside of the feed pipe 4. Under this pressure difference, the second one-way valve 6 on the feed pipe 4 opens, while the first one-way valve 5 on the guide pipe 3 remains closed. Driven by the pressure difference, the paint is then drawn into the feed sleeve 2 through the feed pipe 4, and the second piston plate... As the second piston plate 15 moves upward, the amount of paint drawn into the feed sleeve 2 gradually increases. When the second piston plate 15 moves to a certain position, it changes the direction of movement of the second reciprocating push rod 14, causing its output end to drive the second piston plate 15 downward. At this time, the internal space of the feed sleeve 2 gradually decreases and the pressure increases. When the pressure exceeds the opening pressure threshold of the first one-way valve 5, the first one-way valve 5 opens, and the second one-way valve 6 closes. Under the pushing of the second piston plate 15 and the action of pressure, the paint is quickly pressed into the filter sleeve 7 through the guide pipe 3. After the coating enters the filter sleeve 7, the first reciprocating push rod 11 at the top of the pressure sleeve 1 starts to work. The output end of the first reciprocating push rod 11 drives the first piston plate 12 to move up and down reciprocally inside the pressure sleeve 1. When the first piston plate 12 moves downward, the space inside the pressure sleeve 1 decreases and the pressure increases. This pressure is transmitted to the filter sleeve 7, which is connected to the bottom of the pressure sleeve 1, further causing the coating in the filter sleeve 7 to flow to the bottom. When the first piston plate 12 moves upward, the space inside the pressure sleeve 1 increases and the pressure decreases. However, due to the obstruction of the first one-way valve 5, the coating will not flow back from the guide pipe 3 to the feed sleeve 2. At the same time, the filter sleeve 7... The pressure already formed inside will continue to push the coating to the bottom. Under the continuous action of pressure, the coating in the filter sleeve 7 will continuously converge to the bottom. When the coating comes into contact with the filter screen 9 in the filter cover 8, the filtration process begins. The filter screen 9 has a specific pore size, which allows coating molecules that meet the requirements to pass through, while trapping impurities in the coating on the surface of the filter screen 9. When this utility model is working, the pressure in the pressure sleeve 1 can be monitored in real time by the pressure gauge 24. The operator can understand the filtration status of the coating according to the display value of the pressure gauge 24, and conveniently adjust the working status of the first reciprocating push rod 11 and the second reciprocating push rod 14 in a timely manner.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
