Deep type rotary reverse blowing device

Abstract

The invention relates to a cylindrical filter core reverse blowing and ash-cleaning device for a dust removing device. A deep type rotary reverse blowing device comprises a cover (1), a cavity and a fixed head (3); the top of the cavity is provided with the cover, the bottom of the cavity is provided with the fixed head, the cavity is formed by spicing a plurality of cavity units (2), and a long bolt passes through the cover, the cavity and the fixed head to fix the three components into a whole; a cylindrical wall (205) of each cavity unit is externally connected with a plurality of gas jet arms (202), the cylindrical wall and the gas jet arms communicate from top to bottom, the gas jet arms are uniformly distributed, and the gas jet arms and the cross section of the cylindrical wall at the middle form a circular tooth shape; the top end face of each gas jet arm is an inclined plane extending outwards, and each inclined plane is provided with a plurality of vent holes (201) from top to bottom; the periphery of the top of each cavity unit is provided with a cavity convex groove (203), the periphery of the bottom of each cavity unit is provided with a cavity notch (204), the cavity convex grooves and the cavity notches are matched with each other to make the plurality of cavity units mutually and cooperatively overlapped and mounted from tail to end to form a whole. A fixed head nut (301) is connected to external parts through a thread.

Description

technical field [0001] The invention relates to a dust removal technology, in particular to a back blowing dust removal device for a cylindrical filter element of a dust removal equipment. Background technique [0002] The existing cylindrical filter element of dust removal equipment is blown back to clean the dust: the nozzle of the compressed air is used to blow directly at the filter mouth, and the back blowing port is a large back blowing port, the gas impact force is large, and the manual operation is along the The inner wall of the filter element is back-blown, and its disadvantages are: the inner wall of the filter element that the gas blows to has a large pulse force, and the force on the inner wall of the filter element is uneven, which is easy to cause damage to the filter element, and the dust cleaning is not complete, so that the part of the filter element cannot be cleaned cleanly.

[0002] The existing cylindrical filter element of the dust removal equipment is blown back to clean the dust: the compressed air nozzle is used to blow directly at the filter mouth, and the blowback port is a large blowback port, the gas impact force is large, and the manual operation is along the The inner wall of the filter element is back blown, and its disadvantages are: the inner wall of the filter element that the gas blows to has a large pulse force, the force on the inner wall of the filter element is uneven, and it is easy to cause damage to the filter element, and the dust cleaning is not complete, so that the part of the filter element cannot be cleaned cleanly.

Due to the incomplete cleaning of the filter element, the service life of the filter element is greatly reduced

The traditional way of blowing back the dust of the filter element requires multiple cleanings because it cannot completely clean the dust, which will increase the burden on the compressed air pump and increase the consumption of electric energy, resulting in an increase in electricity costs and labor costs.
