Description

Technical Field

[0001] The utility model relates to the technical field of dust collecting devices, in particular to a dust collection device for a dust reduction chamber. Background Art

[0002] A dust removal chamber, also known as a dust removal chamber, is a settler used to purify gas. Its working principle is to utilize the different specific gravities of dust and gas so that when the dust-laden gas passes through the dust removal chamber, the dust particles naturally settle from the gas by their own gravity. The dust removal chamber has a simple structure, large volume, low resistance, and is easy to maintain, but its purification efficiency is low, generally not exceeding 40%-70%12. The working principle of the dust removal chamber is based on gravity sedimentation. The dust-laden gas enters the sedimentation chamber from one side at a uniform horizontal speed, and the dust particles settle independently at the sedimentation speed. After running for a period of time, the dust particles settle at the bottom of the chamber, and the purified gas is discharged from the outlet on the other side.

[0003] When the current dust reduction chamber is in use, a dust collection bag is set at the outlet of the exhaust pipe, and the bag mouth of the dust collection bag is connected to the air outlet of the exhaust pipe. Then, the bag mouth is tied and connected to the outer wall of the exhaust pipe through a binding rope set at the bag mouth. On the one hand, this connection method is time-consuming and labor-intensive. On the other hand, the outer wall of the exhaust pipe is smooth, and the binding rope will slide down after being tied and connected, which will cause the bag mouth to separate from the exhaust pipe, affecting the normal collection of dust.
