[0022] Please see Figure 1-3 This utility model provides a convenient filter screen 5 structure, including a mounting plate 1. The upper surface of the mounting plate 1 has an installation channel 2. The upper surface of the installation channel 2 has symmetrically distributed connecting grooves 3. The bottom side wall of the connecting grooves 3 has multiple symmetrically distributed installation grooves 4. Each set of installation grooves 4 is symmetrically distributed and has a different depth. Multiple parallel filter screens 5 are arranged inside the installation channel 2. The filter hole diameter of the filter screens 5 decreases from top to bottom, enabling multiple filtration processes. The installation channel 2 can accommodate multiple filter screens 5 with different filter hole diameters, thus enabling graded filtration for different needs.

[0023] Multiple filter screens 5 are fixed to both ends with mounting strips 6. The length of the mounting strips 6 is matched with the depth of the corresponding mounting grooves 4, allowing for a stable snap-fit ​​engagement. After the multiple mounting strips 6 are snapped into their respective mounting grooves 4, the tops of the mounting strips 6 are flush. A limiting groove 7 is formed on one side wall of the connecting groove 3, and a fixing plate 8 is placed inside the limiting groove 7 to press and limit the tops of the multiple mounting strips 6. A fixing bolt 9 is connected to the upper surface of the fixing plate 8. A threaded groove is formed on the bottom side wall of the connecting groove 3, and the fixing bolt 9 is threadedly connected to the threaded groove to fix the position of the fixing plate 8. The mounting plate 1 can be installed in various ways, including snap-fit, bolt, and other mechanical methods, all using existing known technologies.

[0024] This solution has the following working process: When removing and cleaning multiple filter screens 5 inside the mounting plate 1, the two fixing bolts 9 are loosened to release the limiting position of the fixing plate 8. Then, the fixing plate 8 is moved to release the limiting position of multiple mounting strips 6. Then, the filter screens 5 are removed one by one, and the filter screens 5 drive the mounting strips 6 to move out of the mounting grooves 4 one by one. The surface of the filter holes of the filter screen 5 is cleaned. After cleaning, the filter screens 5 are placed into the corresponding mounting grooves 4 in sequence, so that the mounting strips 6 enter the corresponding mounting grooves 4. Then, the fixing plate 8 is moved and enters the limiting groove 7. At the same time, the fixing plate 8 abuts and fixes the multiple mounting strips 6. Then, the fixing bolts 9 are tightened to fix the position of the fixing plate 8.
