[0016] Compared with the prior art, the utility model has the following beneficial technical effects: The air flow enters the inside of the cylinder body through the feed pipe, and drives a plurality of rotating plates to rotate under the impact of the air flow. At the same time, the installation shaft rotates. The air flow in the cylinder body enters the inside of the dust removal tank through the feed pipe again. The filter net provided can intercept and filter the dust. During this process, the installation shaft drives the brush hair mounting rod a and the brush hairs a to rotate. The brush hairs a contact with the outer wall of the filter net, so that the dust accumulated on the surface of the filter net can be removed. The swept dust flows into the inside of the collection box and is collected. To sum up, this technical solution can realize the function of automatically cleaning the filter net during dust removal and filtration. The cleaning structure does not need to add power equipment, has a high degree of automation, low manufacturing cost, and strong practicability. Description of the Drawings

[0020] Embodiment 1

[0021] Such as Figures 1 - 3As shown in the figure, an automatic dust removal device for a cement silo proposed in this embodiment includes a dust removal tank 1, a cylinder body 2, a collection box 3, and an automatic dust removal component.

[0022] A filter screen 11 is installed inside the dust removal tank 1, and an exhaust pipe 62 is communicated with the dust removal tank 1; the collection box 3 is communicated with the bottom end of the dust removal tank 1; the cylinder body 2 is connected to the side of the dust removal tank 1, a feed pipe 61 is communicated with the cylinder body 2, a negative pressure fan is installed on the feed pipe 61, and a connecting pipe 63 is connected between the cylinder body 2 and the dust removal tank 1.

[0023] The automatic dust removal component includes a mounting shaft 8, a brush mounting rod a12, a brush a13, and a plurality of rotating plates 9. The mounting shaft 8 movably penetrates through the end of the dust removal tank 1, and one end of the mounting shaft 8 is arranged inside the cylinder body 2. The plurality of rotating plates 9 are all located inside the cylinder body 2 and are arranged on the mounting shaft 8 in an annular array. The rotating plates 9 are in clearance fit with the inner side of the cylinder body 2. Such a setting prevents the air flow from flowing out through the gap between the rotating plates 9 and the cylinder body 2. The brush mounting rod a12 is installed at the end of the mounting shaft 8, the brush a13 is installed on the brush mounting rod a12, and the brush a13 contacts the surface of the filter screen 11; a brush mounting rod b14 is vertically connected to the brush mounting rod a12, and a brush b15 is installed on the brush mounting rod b14. The brush mounting rod a12 drives the brush mounting rod b14 and the brush b15 to rotate, and the brush b15 can clean the dust accumulated on the inner wall of the dust removal tank 1 during the rotation process.

[0024] One end of the dust removal tank 1 far from the cylinder body 2 is open and is detachably installed with a sealing cover 7. The sealing cover 7 is connected to the filter screen 11. After the sealing cover 7 is removed, the filter screen 11 can be removed from the inside of the dust removal tank 1, so that the filter screen 11 can be conveniently cleaned deeply or replaced.

[0025] One side of the collection box 3 is open, and a drawer 4 is slidably installed on the collection box 3. Pulling out the drawer 4 can facilitate the centralized treatment of the dust collected inside it.

[0026] In this embodiment, one end of the feed pipe 61 is communicated with the inside of the cement silo. When the dust concentration detector installed inside the cement silo detects that the dust concentration exceeds the standard, the control module controls the negative pressure to work, and the dust in the cement silo can be pumped out. The air flow first enters the inside of the cylinder body 2 through the feed pipe 61, and drives the plurality of rotating plates 9 to rotate under the impact of the air flow. At the same time, the mounting shaft 8 is caused to rotate. The air flow inside the cylinder body 2 enters the inside of the dust removal tank 1 through the feed pipe 61 again. The filter screen 11 provided can intercept and filter the dust. During this process, the mounting shaft 8 drives the brush mounting rod a12 and the brush a13 to rotate. The brush a13 contacts the outer wall of the filter screen 11, so that the dust accumulated on the surface of the filter screen 11 can be removed, and the swept dust flows into the inside of the collection box 3 and is collected.

[0027] Embodiment 2
