A pre-dust removal mechanism 2 is installed at the air inlet duct 11, and the pre-dust removal mechanism 2 can filter the dust-laden gas entering the air inlet duct 11, thereby reducing the dust removal pressure at the dust filter cartridge 15 and further improving the dust removal effect.

[0036] Reference Figure 2 and Figure 3 The pre-dust removal mechanism 2 includes a filter plate 21 vertically fixed in the air inlet duct 11. The number of filter plates 21 is multiple, and the multiple filter plates 21 are arranged at intervals along the length direction of the air inlet duct 11. A fixing component 22 is provided between each filter plate 21 and the inner wall of the air inlet duct 11. The filter plate 21 is installed in the air inlet duct 11 through the fixing component 22. When the filter plate 21 needs to be disassembled, it can be quickly disassembled and replaced; an opening 111 is provided on the side of the air inlet duct 11 close to the ground, and a dust collecting shell 23 is also installed on the lower side of the air inlet duct 11, and the dust collecting shell 23 is connected with the air inlet duct 11 through the opening 111. A mounting component 24 is provided between the outer wall of the air inlet duct 11 and the dust collecting shell 23, and the mounting component 24 further facilitates the disassembly and fixation of the dust collecting shell 23.

[0037] On one side of each filter plate 21 away from the box body 1, there is a convex portion 211, which protrudes towards the side away from the box body 1, further increasing the contact area with the dust-containing gas and reducing the blockage of the filter plate 21. The upper sides of the filter plates 21 are in contact with the inner wall of the air inlet duct 11, and the lower sides of the filter plates 21 extend into the dust collection housing 23 and are in contact with the inner wall of the dust collection housing 23.

[0038] Referring Figure 3 and Figure 4 Figure, the fixing assembly 22 includes fixing bars 221 vertically fixed on the inner wall of the air inlet duct 11. One fixing bar 221 is fixed on each side of each filter plate 21. A sliding groove 2211 is formed in the fixing bar 221, and the sliding groove 2211 is vertically formed along the length direction of the fixing bar 221.

[0041] The implementation principle of a dust removal device according to an embodiment of the present application is as follows:

[0042] When the dust removal work is carried out, the dust-containing air enters the box body 1 from the air inlet pipe 11. After being filtered by the dust removal filter cartridge 15, it flows out from the air outlet pipe 12. The dust intercepted by the dust removal filter cartridge 15 can finally be discharged from the ash outlet 13. The pre-dust removal mechanism 2 in the air inlet pipe 11 pre-filters the large-particle dust, thereby reducing the dust removal pressure of the dust removal filter cartridge 15. The dust intercepted by the filter plate 21 will fall into the dust collection housing 23. The dust collection housing 23 can be disassembled and cleaned through the mounting assembly 24. The filter plate 21 is fixed in the air inlet pipe 11 through the fixing assembly 22, reducing the displacement of the filter plate 21 and ensuring its filtering effect. The brush strip 25 and the scraping assembly 26 can scrape the filter plate 21 to reduce the blockage of the filter plate 21.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
