Self-cleaning vibrating bag-type dust remover

Abstract

The invention discloses a self-cleaning vibrating cloth bag dust collector, which comprises a dust removal box body, a cleaning box body is fixed on the top of the dust removal box body, horizontally distributed cloth bag fixing frames are vertically fixed on the side wall of the dust removal box body, the dust removal box body and cleaning The boxes are separated by a cloth bag fixing frame. The bag fixing frame is sealed and fixed with a dust removal bag. The bag support frame is set in the dust removal bag. The air inlet channel is fixed at the entrance of the flue gas, the bottom of the dust bag is fixed with a first snap ring, the outer surface of the side wall of the dust removal box is covered with a fixed bearing ring, and the bottom of the bearing ring is vertically and evenly distributed with four supporting columns , a motor is fixed on the surface of the bearing ring. The present invention is provided with a vibrating frame, which is connected to the dust-removing cloth bag through a buffering and pulling mechanism, and the reciprocating motion of the vibrating frame drives the reciprocating vibration of the dust-removing cloth bag, and the vibration amplitude is relatively large, which can safely realize the self-cleaning ability of the dust-removing cloth bag.

Description

technical field [0001] The invention belongs to the field of garbage incineration and relates to a self-cleaning vibration bag filter. Background technique [0002] The bag filter, also known as filter dust collector, is a dry high-efficiency dust collector. It is a dust removal device that uses bag filter elements made of fiber woven fabrics to capture solid particles in dusty gases. Its working principle is dust When the particles are wound around the filter cloth fibers, they are intercepted by the collision of the fibers due to the inertial force. The existing dust removal bag blows off the accumulated dust on the surface of the dust removal bag through the back blowing function when cleaning the dust. It is necessary to install the back blowing in the cleaning box. For large-scale dedusting gas, due to the large amount of dust on the surface of the dust removal bag after the dust removal, it is easy to cause the surface gap of the dust removal bag to become smaller or e...

[0002] The bag filter, also known as filter dust collector, is a dry high-efficiency dust collector. It is a dust removal device that uses bag filter elements made of fiber woven fabrics to capture solid particles in dusty gases. Its working principle is dust When the particles are wound around the filter cloth fibers, they are intercepted by the collision of the fibers due to the inertial force. The existing dust removal bag blows off the accumulated dust on the surface of the dust removal bag through the back blowing function when cleaning the dust. It is necessary to install the back blowing in the cleaning box. For large-scale dedusting gas, due to the large amount of dust on the surface of the dust removal bag after the dust removal, it is easy to cause the surface gap of the dust removal bag to become smaller or even blocked during the subsequent dust removal process, slowing down the dust removal speed , reduce dust removal efficiency

[0003] The utility model patent with the patent application number of 201621096195.5 discloses a dust-removing bag for boilers. By connecting a spring under the bag and setting a swing belt in the middle of the bag body, dust removal can be achieved through the shaking and vibration of the spring and the belt. However, the spring of the dust-removing bag The connection between the bottom end and the middle of the boiler is difficult. At the same time, the long-term spring is likely to cause the spring to lose its elastic deformation ability and shorten the service life of the spring. At the same time, due to the small shaking of the spring and the belt itself, it is impossible to achieve complete self-cleaning of the dust bag
