[0002] Dust collector refers to equipment used to separate dust from flue gas. Industrial dust mainly comes from mechanical crushing and grinding of solid materials, mixing, screening, packaging and transportation of powdered materials, smoke generated by materials, and oxidation and condensation of steam generated in the air when materials are heated.

[0003] Bag dust collector is a commonly used dust removal equipment in gas dust removal. When the gas is dusted, the dust in the gas adheres to the outer wall of the dust bag. After the dust removal is completed, recoil gas is introduced to remove the dust on the outer wall of the dust bag to prevent dust from clogging the dust bag. When recoil gas is introduced to remove the dust from the outer wall of the dust bag, the recoil gas vertically contacts and impacts the bottom end of the dust bag. After the dust at the bottom of the dust bag is separated, the air permeability of the bottom end of the dust bag increases, and the recoil gas is released from the bottom end of the dust bag, thereby reducing the dust removal effect of the side wall of the dust bag.

[0023] The anti-blocking mechanism 4 includes an air guide component 41, which is fixedly connected to the housing 1, and the bottom end of the air guide component 41 is connected to a plurality of dispersion components 42, each dispersion component 42 is inserted into a corresponding dust removal bag 3;

[0024] The dispersion component 42 includes a hollow tube rack 421, which is connected to the air guide component 41, and the hollow tube rack 421 is inserted into the dust removal bag 3. A first through hole 422 is opened at the bottom end of the hollow tube rack 421, and a plurality of second through holes 423 are opened on the hollow tube rack 421 at equal intervals along the length direction. The aperture of the first through hole 422 is larger than the aperture of the second through hole 423.

[0025] Working process:

[0026] The dusty gas is introduced into the housing 1 through the air inlet pipe, and the introduced gas contacts the dust removal bag 3. The dust removal bag 3 removes dust from the gas, and the dust in the gas adheres to the outer wall of the dust removal bag 3. The dust-removed gas enters the dust removal bag 3, and the gas in the dust removal bag 3 moves upward and is released from the air outlet pipe;

[0027] After the gas dust removal is completed, the external pressure gas is introduced into the gas guide component 41, and the pressure gas in the gas guide component 41 is introduced into the hollow tube rack 421. A part of the gas in the hollow tube rack 421 is released from the first through hole 422, and the released gas performs air impact dust removal on the bottom end of the dust bag 3. Another part of the gas in the hollow tube rack 421 is released from the second through hole 423, and the gas released from the second through hole 423 impacts the side wall of the dust bag 3, causing the dust on the side wall to fall off. The pressure gas removes dust from the bottom end and side wall of the dust bag 3 respectively, thereby improving the dust removal effect of the dust bag 3 and avoiding blockage of the dust bag 3.

[0028] Embodiment 2: In embodiment 1, when the pressurized gas is introduced into the gas guide assembly 41, the gas cannot be uniformly dispersed and introduced into different hollow tube racks 421. Figure 4 As another preferred embodiment of the utility model, the difference from embodiment 1 is that the air guide component 41 includes a second fixed plate 411, the second fixed plate 411 is sprayed with an anti-corrosion layer, one side of the second fixed plate 411 is fixedly connected to the shell 1, and the other side of the second fixed plate 411 is fixedly connected to a circular hollow frame 412, the circular hollow frame 412 is connected with an air intake pipe 413, one end of the air intake pipe 413 extends to the outside of the shell 1, and a valve 414 is fixedly connected to the air intake pipe 413. A plurality of jet ports 415 are provided at equal intervals along the length direction at the bottom end of the circular hollow frame 412, each jet port 415 is connected to a hollow pipe frame 421, and the valve 414 is opened, and the external pressure gas is introduced into the circular hollow frame 412 through the air intake pipe 413, and the gas in the circular hollow frame 412 is dispersed and introduced into different jet ports 415, so that the pressure is evenly released from different jet ports 415.

[0029] Example 3: In Example 1, when the dust on the dust bag 3 is removed by pressurized gas, the bonding strength between the dust and the dust bag 3 is relatively large, and it is not easy to remove the dust on the dust bag 3. Figure 2 As another preferred embodiment of the utility model, on the basis of embodiment 1, an oscillation mechanism 5 is connected to the upper end of the shell 1, and the oscillation mechanism 5 includes an electric telescopic rod 51, which is fixedly connected to the upper end of the shell 1, and the telescopic end of the electric telescopic rod 51 extends into the shell 1 and is fixedly connected to a mounting plate 52, and a sphere 53 is fixedly connected to the bottom end of the mounting plate 52, and the mounting plate 52 and the sphere 53 are an integral structure. After the electric telescopic rod 51 is powered on and started, it drives the mounting plate 52 to move downward a set distance and then resets, and the mounting plate 52 drives the sphere 53 to move downward, and the sphere 53 collides with the first fixed plate 2 after moving downward a set distance, and vibration is generated after the collision, and the generated vibration is transmitted to the dust bag 3, thereby reducing the bonding strength between the dust bag 3 and the dust, so as to facilitate the gas to remove the dust on the dust bag 3.
