[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0016] Please refer to Figure 1-2 , the present utility model provides a technical solution: a multi-layer filtration type dust collector filter element, including a support keel 7 and a chassis 8. The support keel 7 is welded to the center of the chassis 8, and an inner ring filter screen 6 is sleeved outside the support keel 7.

[0017] The chassis 8 is also welded with outer support columns 3 and support columns 5 that are evenly distributed in a circle. The outer support columns 3 are arranged in the outermost circle, and the support columns 5 are arranged between the outer support columns 3 and the support keel 7. The outer support columns 3 and the support columns 5 have the same diameter, height, and number, and the outer support columns 3 and the support columns 5 are staggered.
