The three filter screens form a multi-layer protection, layer by layer intercepting sundries of different sizes, maximizing the air purity entering the dust removal system, significantly improving the filtering effect, and ensuring the efficient operation of the whole dust removal system.

[0032] In a preferred embodiment, the mesh size of the third filter screen 11 is 1-5 mm, which can effectively intercept tiny particle sundries, greatly refine the filtering effect, and ensure that only a small amount or even almost no sundries can enter the main air pipe 2 and the subsequent dust removal system through the filtering assembly, thereby fully protecting the normal operation of each component in the system, reducing equipment maintenance costs, and improving equipment working efficiency.

[0033] In a preferred embodiment, the diameter of the air pipe branch is 1 / 5-1 / 2 of the diameter of the main air pipe 2, and the dust remover 1 is a bag-type dust remover 1. The diameter of the air pipe branch 6 is 1 / 5-1 / 2 of the diameter of the main air pipe 2. This ratio can reasonably control the amount of air introduced into the air speed adjusting mechanism 5, neither too much air due to too large pipe diameter nor limited air speed adjustment range due to too small pipe diameter. The bag-type dust remover 1 has high dust removal capacity and can effectively filter dust, greatly improving the dust removal effect of the whole dust removal fan 3 and meeting the strict requirements of industrial production on air quality.
