[0021] like Figure 1-4 As shown, a pulse dust collector with high dust removal efficiency includes a dust collector body 2. The dust collector body 1 is divided into two upper and lower chambers by a filter bag mounting plate 4, wherein the upper chamber is an upper box body 10, and the lower chamber is a dust removal box body.

[0022] Several filter bags 3 installed at the bottom of the filter bag mounting plate 4 are arranged evenly in the dust removal box, and several filter bags 3 are distributed in a matrix on the filter bag mounting plate 4. An ash hopper 11 is installed below the filter bag 3, and an ash discharge device is installed on the ash discharge port at the bottom of the ash hopper 11 (this is a prior art method and will not be described in detail here). A dust gas inlet 1 is installed at a position on one side of the bottom of the dust collector body 1, and a dust cleaning device is installed between adjacent filter bags 3. A blow pipe 7 is installed in the upper box body 10, and the air inlet end of the blow pipe 7 is connected to the air bag 5 after passing through the upper box body 10. A venturi tube 8 is installed at the bottom of the blow pipe 7 above the filter bag 3. A clean air outlet 9 is installed at a position on one side of the upper box body 10.

[0023] The dust cleaning device includes a rotating shaft 13, on which a plurality of sleeves 14 are rotatably sleeved, and a plurality of arc-shaped spring pieces 15 are distributed circumferentially on the outer periphery of the sleeve 14. One end of the rotating shaft 13 away from the sleeve 14 is fixedly connected to a driving device, and the driving device is connected to a lifting mechanism.

[0024] The driving device can drive the rotating shaft 13 to rotate, thereby causing the arc-shaped spring piece 15 to rotate. During the rotation process, the arc-shaped spring piece slaps on the outer surface of the filter bag 3 to knock off the dust on it, thereby avoiding clogging and affecting the filtering effect. At the same time, the lifting mechanism drives the driving device to move up and down, thereby driving the elastic spring piece 15 to move up and down, so as to meet the needs of beating the filter bag 3 at different heights, thereby improving the cleaning quality and efficiency.

[0025] The blow pipe 7 is provided with a pulse valve 6 .

[0026] The driving device adopts a motor 16, specifically a reduction motor.

[0027] The lifting mechanism includes a nut block 17 fixedly connected to the driving device, and a screw rod 19 is threadedly connected to the nut block 17, and the screw rod 19 is connected to the forward and reverse motor. The end of the nut block 17 away from the driving device is fixedly connected to a slider 18, and the slider 18 is slidably connected to a slide rail 20, and the slide rail 20 is fixedly installed on the inner side wall of the dust collector body 1. According to the screw principle, the forward and reverse motor drives the screw 19 to rotate, and the nut block 17 moves up and down along the slide rail 20 under the limiting action of the slider 18 and the slide rail 20, thereby realizing the lifting operation.

[0028] A plurality of brackets 12 are symmetrically mounted on the bottom of the dust collector body 1 .

[0029] The action process of the utility model is as follows:

[0030] First, the pulse valve 6 is opened, and the high-pressure gas in the air bag 5 is ejected from the blowing pipe 7 to the venturi 8, and the ejected gas is discharged from the inside of the filter bag 3 to the outside; then, the driving device drives the rotating shaft 13 to rotate, thereby rotating the arc-shaped spring piece 15. During the rotation process, the arc-shaped spring piece 15 hits the outer surface of the filter bag 3, and cooperates with the gas to knock down the dust on it, thereby reducing blockage; finally, the lifting mechanism drives the driving device to move up and down, thereby driving the elastic spring piece 15 to move up and down, so as to meet the needs of hitting the filter bag 3 at different heights, thereby improving the cleaning quality and efficiency.

[0031] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
