Description

Dust collector is used in workshop production

Technical Field

The utility model relates to the technical field, concretely relates to dust collector is used in workshop production.

Background

The dust collector has the advantages that a lot of dust is generated in the production and processing process, when the dust is suspended in the air and reaches a certain concentration, once sparks, electric arcs and the like are encountered, explosion is easy to occur, the safety of a production workshop is greatly influenced, in addition, the operation environment of workers can be influenced due to the existence of workshop dust, once the dust is acknowledged to be absorbed into the body, the health of the workers can be seriously harmed, and therefore the dust collector needs to be matched with the corresponding dust collector.

The bag-type dust collector is a relatively common dust collector at present, and the working process is as follows: the dust-containing gas enters into the dust removing bag, the thicker particles directly fall into the dust hopper or fall into the dust hopper after colliding with the inner wall of the dust removing bag, the thinner dust is attached to the filtering surface of the dust removing bag after filtering, the filtered gas is discharged into the atmosphere by the fan, in the process of dust removing, a layer of dust is accumulated on the surface of the cloth bag due to the effects of filtering, colliding, detenting, diffusing, static electricity and the like, the layer of dust is called as a primary layer, in the later motion process, the primary layer becomes a main filtering layer, but the efficiency and the resistance of the cloth bag dust remover are correspondingly increased along with the accumulation of the dust on the surface of the cloth bag, when the pressure difference between two sides of the cloth bag is large, some fine dust particles attached to the cloth bag are extruded into the cloth bag, so that the efficiency of the dust remover is reduced, in addition, the air volume of the dust removing system is obviously reduced due to the overhigh resistance of the cloth, therefore, after the resistance of the bag-type dust collector reaches a certain numerical value, the bag-type dust collector needs to clean dust in time, a certain amount of fine dust can be accumulated in a dust removing hopper of the bag-type dust collector in the using process and cannot be discharged, when the bag-type dust collector does not work, the fine dust can adsorb moisture in air, so that the dust removing hopper is corroded and damaged, and the service life of the bag-type dust collector is seriously influenced.
