Low-pressure pulse filter bag dust collector

Abstract

The invention belongs to the technical field of dust collecting devices and particularly relates to a low-pressure pulse filter bag dust collector. The low-pressure pulse filter bag dust collector comprises a middle box, a dust bucket and a pulse injection device, wherein the dust bucket is arranged at the bottom of the middle box, and the inside of the dust bucket is provided with an airflow distributing plate; the middle box is provided with an air inlet and an air outlet, and the upper portion of the middle box is provided with an air purifying chamber; the pulse injection device is arranged inside the air purifying chamber; the inside of the middle box is provided with a cloth bag communicated with the pulse injection device; the dust bucket is composed of a fixed barrel and a rotary barrel, the rotary barrel is arranged inside the fixed barrel and rotatingly connected with the fixed barrel, scrapers are hinged to the fixed barrel and are in contact connection with the inner wall of the rotary barrel, the rotary barrel can eject the scrapers during rotation, and the scrappers can hit the inner wall of the rotary barrel when falling down. The low-pressure pulse filter bag dust collector is simple in structure, large in processing air capacity and good in dust collecting effects.

Description

technical field [0001] The invention belongs to the technical field of dust removal devices, and in particular relates to a low-pressure pulse filter bag dust collector. Background technique [0002] Bag filter is a common dust removal equipment, which is widely used in various industries. The bag filter is a dry dust filter device. When the dust-containing gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the effect of gravity and fall into the ash hopper. When the gas containing fine dust passes through the filter material, the dust will be blocked and the gas will get cleansed. But there are multiple defects in the existing bag filter, so people improve this. For example, the utility model patent with the patent application number 201420087556.4 discloses a low-pressure pulse bag filter, which can increase the processing air volume and ensure the cleaning effect and dust removal efficiency; the utility model patent wi...
