Industrial environment-friendly bag type dust collector for dust removal

Abstract

The invention discloses an industrial environment-friendly bag type dust collector for dust removal. The bag type dust collector structurally comprises an air suction opening, an upper cover, a filtercartridge and a dust collector, the upper cover is located at one end of the filter cartridge, the air suction opening is fixedly formed in one side of the upper cover, the filter cartridge is in butt joint with the dust collector, the interiors of the filter cartridge and the dust collector are communicated, a binding sleeve is in threaded locking connection with a dust collecting bag through anannular top plate, and the binding sleeve plays a role in elastically locking the dust collecting bag under the action of an opening and expanding piece, so that the phenomenon that the elastically locked cloth bag is stretched and shaken due to the impact force of smoke when the dust collecting bag is sprayed to the opening and expanding piece from a supporting and guiding device due to downwardimpact waste gas is prevented; and a dust collecting bucket is of a tapered structure with a big top and a small top to facilitate dust discharge, and through cooperation of a dispersing structure and a dispersing pipe, the wind direction is more dispersed, waste gas and dust in the dust collecting bucket are distributed more evenly, and meanwhile, the dispersing structure can play a certain rolein buffering, so impact borne by the dispersing structure can be reduced.

Description

technical field [0001] The invention relates to the field of industrial environmental protection, in particular to a bag-type dust collector for industrial environmental protection dust removal. Background technique [0002] The existing bag-type dust collector bag cage is usually made of rigid material, including vertical ribs and ring ribs. The vertical ribs and ring ribs form a cylindrical keel, and the dust bag is fixed on the keel by fixing means. [0003] After using for a period of time, a large amount of dust will be stained on the mouth of the dust bag. Since the bag cage is made of rigid material, high-pressure air is generally used to blow the dust into the dust bag at high speed in a short period of time to remove dust, resulting in dust bag The fiber gap of the bag mouth is frequently stressed, which increases the damage and replacement rate of the filter bag, and if the temperature drops to condensation, a large amount of acid, alkali and hygroscopic dust will...

Problems solved by technology

[0003] After using for a period of time, the bag opening of the dust bag will be stained with a lot of dust. Since the bag cage is made of rigid material, high-pressure air is generally used to blow the dust into the dust bag at a high speed in a short period of time to remove dust, resulting in dust bags The fiber gap of the bag mouth is frequently stressed, which increases the damage and replacement rate of the filter bag, and if the temperature drops and condensation occurs, a large amount of acid, alkali substances and hygroscopic dust will adhere to the bag mouth, and the long-term connection between the dust bag and the bag cage Rust or corrosion and bonding will occur, which not only affects the service life of the dust bag, increases production costs and production safety, but also limits the filter effect of the bag dust collector on dusty gas
