Description

Anti-blocking and anti-explosion central dust collection system Technical Field The utility model relates to the technical field of central dust collection, in particular to an anti-blocking and anti-explosion central dust collection system. Background A central dust collection system is a large air purification system used in industrial or commercial environments for the centralized collection, handling and discharge of dust, debris, fumes, and other pollutants. The device uniformly collects and processes pollutants of a plurality of dust producing points through a set of complete pipeline network, a filtering device and power equipment, is widely applied to industries such as machining, chemical industry, pharmacy, food processing, electronic manufacturing and the like, and is an important device for improving production environment, guaranteeing occupational health and meeting environmental protection requirements. When the existing central dust collector is used for treating dust containing metal wires, the conical hopper is easy to be blocked due to the winding of the metal wires, and the traditional back blowing ash removal or mechanical vibration mode has poor effect on the blocking. Meanwhile, if the crusher is adopted to treat the blockage problem, dust explosion is easy to be caused, and the effect of a single vacuum conveying mode is limited.
