Description

Bag type dust collector

Technical Field

The utility model belongs to the dust collecting equipment field, in particular to bag type dust collector.

Background

The bag type dust collector is a dry type dust filtering device. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified.

The existing bag type dust collector is not provided with an ash removal device in the using process, the bag is mainly knocked manually to remove ash, the working efficiency is greatly reduced, and certain influence is generated on the body of a worker by dust generated when the manual strength and ash removal are improved. The ash removal mode of part of bag type dust collectors adopts pulse blowing ash removal mode, and the pulse blowing ash removal mode is that high-pressure air is blown into a filter bag at a high speed in a short time (usually not more than 0.2 second) to generate back-blowing airflow opposite to filtering airflow, so that pulse expansion vibration is generated in the filter bag, the wall of the filter bag obtains high outward acceleration, and dust is shaken off. This approach is dynamic ash removal. The ash removal mode has the advantages that the machine is stopped to remove ash, the production efficiency is influenced, in addition, the ash removal time is short, the ash deposition at certain local parts is difficult to clean along with the reduction of the transmission action of compressed air along with the increase of the distance, and the ash removal and dust removal effects are influenced by the residual ash deposition.
