Bag-type dust collector with efficient ash removal function

Abstract

The invention discloses a bag-type dust collector with an efficient dust removal function, which comprises a support net rack, the outer side of the support net rack is sleeved with a filter bag, and a top mounting plate is fixed at the top end of the support net rack; the outer side of the filter bag is movably sleeved with an outer cylinder, a bottom mounting plate is rotationally arranged at the bottom end of the outer cylinder, a brush is arranged on the inner wall of the outer cylinder, the brush is spiral and makes contact with the filter bag, a stepping motor is fixedly mounted on the bottom mounting plate, a driving gear is fixed to a driving shaft of the stepping motor, and the driving gear is driven by the stepping motor to rotate. The bottom of the outer wall of the outer barrel is fixedly sleeved with a gear ring, the gear ring is meshed with the driving gear, a driving block is fixed to the position, close to the bottom mounting plate, in the outer barrel in a suspended mode, the driving block is located below the filter bag, and a screw rod is fixed to the driving block and penetrates through the supporting net rack. According to the bag-type dust collector with the efficient ash removal function, the integrity of the primary layer of the filter bag is ensured while the ash of the filter bag is removed.

Description

technical field [0001] The invention belongs to the technical field of bag dust collectors, and in particular relates to a bag dust collector with high-efficiency dust removal function. Background technique [0002] The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. The working principle is that the dust-laden air enters the cylindrical filter bag from the lower orifice plate. When passing through the pores of the filter bag, the dust is captured on the filter bag and passes through The clean gas from the filter bag is discharged from the discharge port. The dust deposited on the filter bag can fall off from the surface of the filter bag under the action of mechanical vibration and fall into the ash hopper. [0003] In the process of realizing the present invention, the inventors have found that at least the following problems exist in this technology: after the filter bag has been used for a period of time, due to effects...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, the current cleaning mainly adopts gas cleaning, mechanical vibration cleaning and manual knocking, which easily destroys the first layer on the filter bag and affects the subsequent filtration efficiency of the filter bag. , and a bag filter with high-efficiency dust removal function is proposed
