Description

Spraying tower type structure for shot blasting machine dust treatment

Technical Field

The utility model belongs to the technical field of shot-blasting machine dust disposal, a spray tower structure for shot-blasting machine dust disposal is related to.

Background

The surface treatment process often needs to use a shot blasting machine to pretreat products, a large amount of dust can be generated in the shot blasting process, and dust treatment is mainly carried out through a dust removal device of the shot blasting machine at present. After the dusty gas enters a large settling chamber, the cross-sectional area of the settling chamber is much larger than that of a dust absorption pipeline, so that the flow velocity of the dusty gas of the shot blasting machine is greatly reduced, and the flow velocity can be reduced by 10-20 times. During the time period in which the dusty gas passes through the settling chamber, the larger dust particles have sufficient time to settle by gravity in the settling chamber and the cleaned dusty gas is discharged from the other end of the settling chamber. The settling chamber is a dust collecting device which makes dust naturally settle by utilizing the action of gravity, so the settling chamber is also called as a gravity settling chamber and is called as a settling chamber for short.
