detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, the utility model provides a technical solution: a filter screen device with adjustable filter hole size, including a first filter screen layer 1, a second filter screen layer 2 and a third filter screen layer 3, The first filter screen layer 1, the second filter screen layer 2 and the third filter screen layer 3 are all embedded in the sleeve frame 4, and the first filter screen layer 1, the second filter screen layer 2 and the third filter screen layer Both sides of the mesh layer 3 are symmetrically provided with support rods 8, and both sides of the sleeve frame 4 are sequentially provided with a first through groove 5, a second through groove 6 and a third through groove 7 from top to bottom. The filter mesh layer 1 , the second filter mesh layer 2 and the third filter mesh layer 3 are all provided with filter holes 10 .

A tightening nut 9 is provided at the bottom of the sleeve frame 4 . When it is necessary to adjust the passing capacity of the filter screen, the tightening nut 9 can be loosened, and after adjustment, the tightening nut 9 can be tightened to ensure that the first filter screen layer 1, the second filter screen layer 2 and the third filter screen layer 3 are in use. keep it steady. The first filter layer 1 , the second filter layer 2 and the third filter layer 3 have the same structure. The first through-slot 5, the second through-slot 6 and the third through-slot 7 have the same specifications, the diameter of the pole 8 is smaller than the width of the first through-slot 5, the first filter layer 1, the second filter layer 2 and the struts 8 on the third filter layer 3 respectively pass through the first through groove 5 , the second through groove 6 and the third through groove 7 . The strut 8 can be freely adjusted in the first slot 5 , the second slot 6 and the third slot 7 .

Specifically, during use, when the positions of the first filter screen layer 1, the second filter screen layer 2 and the third filter screen layer 3 are relatively overlapped, the passing capacity of the filter hole 10 is the maximum at this time, and when the filter capacity needs to be changed, you can Screw the tightening nut 9 so that the gap between the first filter layer 1, the second filter layer 2 and the third filter layer 3 becomes larger, and adjust the first filter layer 1 and the second filter layer through the pole 8 2 and the third filter layer 3 are relatively positioned to change the passing capacity of the filter hole 10, and the tightening nut 9 can be tightened after the adjustment is completed.
