[0010] Beneficial effects

[0011] This utility model provides a modular filter cloth with the following advantages:

[0012] The design of the base frame, top frame, and filter cloth body allows for easy assembly and disassembly of the filter cloth. When a part of the filter cloth body is damaged, only the corresponding part of the filter cloth needs to be replaced, without replacing the entire filter cloth, which saves costs. At the same time, different specifications of filter cloth bodies can be selected according to different filtration needs and assembled through the base frame and top frame to achieve flexible adjustment of the filter cloth and improve its applicability.

[0013] The pressure ring on the lower wall of the top frame and the annular groove on the upper wall of the base frame work together to press the edge of the filter cloth body tightly, ensuring the sealing between the filter cloth and the base and top frames. The connecting sleeve is screwed to the locking ring by threads, and the auxiliary connecting components between the upper ring and the fixed ring enhance the connection stability between the base and the top frame, making the filter cloth less prone to loosening during use and ensuring the reliability of the filtration effect.

[0014] The filter cloth body is composed of a polypropylene nonwoven fabric layer and a PTFE-coated polyester base fabric layer. The polypropylene nonwoven fabric layer can initially filter larger particulate impurities, while the PTFE-coated polyester base fabric layer can further filter small particles and improve filtration accuracy. The design of hook-and-loop nylon Velcro and nonwoven nylon Velcro allows the two filter cloths to fit tightly at the edges, making it convenient to install and replace the two filter cloths.
