Abstract
Description
Technical Field
[0001] The present application relates to the technical field of dust removal equipment, and in particular to a bag dust collector receiving device. Background Art
[0002] The bag filter is a high-efficiency dry dust filtering device. Its high dust removal efficiency is inseparable from its dust removal mechanism: when the dust-laden gas enters the ash hopper through the guide plate from the lower air intake duct of the dust collector, the coarse dust will fall into the ash hopper due to the collision of the guide plate and the reduction of gas velocity, and the remaining fine dust particles will enter the filter bag chamber with the gas. Due to the inertia, diffusion, barrier, hooking, static electricity and other effects of the filter material fibers and fabrics, the dust is retained in the filter bag, and the purified gas escapes from the bag and is discharged through the exhaust pipe. The dust accumulated on the filter bag is removed by gas backwashing, and the removed dust falls into the ash hopper.
[0003] In the related art, a conveyor belt is usually set at the lower end of the ash hopper, and the dust in the ash hopper will fall on the conveyor belt and be transported to the collection area by the conveyor belt. However, there is usually a certain distance between the conveyor belt and the ash hopper. When the dust discharged from the ash hopper falls on the conveyor belt, some dust may be generated, and then the dust is easily spread to the surrounding environment, causing secondary pollution.
