[0018] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the technical solutions in the present invention are further described below in conjunction with the accompanying drawings and embodiments.

[0019] See also Figure 1 and Figure 2As shown, a flue gas dust removal device comprises: a dust removal box 1, an air inlet 11, an air outlet 12, an internal fixed top block 2, a first vertical plate 3 and a first filter screen plate 4; the air inlet 11 and the air outlet 12 are respectively arranged on opposite sides of the dust removal box 1, the internal fixed top block 2 is fixed to the top of the dust removal box 1, the first vertical plate 3 is located at the bottom of the internal fixed top block 2, and the first vertical plate 3 is elastically arranged on the internal fixed top block 2 in the horizontal direction, and the first filter screen plate 4 is fixedly connected to the lower part of the first vertical plate 3, and a toggle plate 5 for toggle the first vertical plate 3 is also provided in the dust removal box 1.

[0020] The gas to be treated enters the dust removal box 1 from the air inlet 11, is filtered and dust-removed by the first filter screen 4, and then is discharged from the dust removal box 1 through the air outlet 12. After long-term use, a lot of dust is accumulated on the first filter screen 4. The first vertical plate 3 is moved by setting a toggle plate 5. Because the first vertical plate 3 is elastically set on the internal fixed top block 2, under the action of elasticity, the first vertical plate 3 shakes and shakes off the accumulated dust on the first filter screen 4 fixed below, thereby improving the dust removal efficiency.

[0021] Furthermore, if Figure 1 and Figure 2 As shown, a driving motor 13 is fixed to the rear side of the dust removal box 1, and the output end of the driving motor 13 extends into the dust removal box 1 and is coaxially fixed with a rotating shaft. One end of the toggle plate 5 is fixed to the rotating shaft, and one side of the other end is provided with an inclined surface inclined to the other side. The driving motor 13 is set to drive the rotating shaft to rotate, and drive the toggle plate 5 to rotate. The axis of the rotating shaft is perpendicular to the moving direction of the first vertical plate 3. Figure 1 In the embodiment, the rotating shaft rotates in the counterclockwise direction, and an inclined plane is provided. When rotating, the inclined plane contacts the first vertical plate 3, so that the toggle plate 5 rotates smoothly.

The upper end of the first vertical plate 3 is slidably connected to the internal fixed top block 2 in the horizontal direction, and the first vertical plate 3 can move on the internal fixed top block 2, and a compression spring 7 is provided. When the toggle plate 5 rotates, the first vertical plate 3 is toggled to move in a direction away from the rotation axis, and the compression spring 7 is compressed until the first vertical plate 3 moves to the farthest position, and the compression amount of the compression spring 7 is the largest at this time, and then the toggle plate 5 continues to rotate, and under the elastic force of the compression spring 7, the first vertical plate 3 eventually returns to its original position.

[0023] Furthermore, if Figure 1As shown, two first vertical plates 3 are provided, and the two first vertical plates 3 are symmetrically arranged on both sides of the rotating shaft, and the size of the filter mesh of the two first filter screens 4 gradually decreases from the air inlet 11 to the air outlet 12. Two first filter screens 4 are provided for secondary filtering to improve the dust removal effect, and the size of the filter mesh of the two first filter screens 4 gradually decreases from the air inlet 11 to the air outlet 12 to filter smaller dust particles and further improve the dust removal effect.
