Mechanical ash removing device of a bag-type dust catcher

Abstract

The invention provides a mechanical ash removing device of a bag-type dust catcher, comprising a box body, a suspending bracket which is arranged on the upper part of the interior of the box body forsuspending multiple bags and can move up and down, a beam arranged above the suspending bracket and fixedly connected with the box body, a pressure pole arranged at the center position of the beam andfixedly connected with the suspending bracket, a pressure board arranged at the top end of the pressure pole, a spring sheathed on the pressure pole between the beam and the pressure board, and a rotary shaft arranged right above the pressure board and provided with a fork for compressing the spring. The suspending bracket together with the bags suddenly bounds upward after being compressed to the lowest point by rotating the rotary shaft, so that dusts adhered on the surface of the bags fall down freely and rapidly due to inertia, thus dusts are removed; the suspending bracket is continuously driven by the spring to move upward to the top, the speed of the suspending bracket is changed to zero suddenly for secondary ash removing; when the rotary shaft rotates one cycle and the pressure pole does reciprocated movement one time, and the suspending bracket and the bags have two-time speed mutation for ash removing twice with ideal ash removing effect.

Description

technical field [0001] The invention relates to a dust remover, in particular to a mechanical dust removal device for a bag type dust remover. Background technique [0002] The existing bag-type dust collectors are divided into three categories according to the way of dust removal, one is mechanical vibration and rapping, the other is blowing back with fan, and the third is pulse of compressed air; the first category is simple in structure but clean. The ash effect is poor; the effect of the second type is average; the third type has the best effect, but because of the large number of pulse valves and blowing pipes, there are defects such as easy failure, and the dust is rushed to the adjacent bag when cleaning. [0003] The designer of this patent proposed a mechanical dust removal scheme with ideal effect in the patent application whose application number is 2009101350321 and the name is mechanical dust removal bag filter. The defect is that compressed air is needed. Con...

Problems solved by technology

[0002] The existing bag filter is divided into three categories according to the cleaning method, one is the mechanical vibration and rapping type, the other is the fan back suction and back blowing type, and the third is the compressed air pulse type; the first type is simple in structure but clean. The ash effect is poor; the effect of the second type is average; the third type has the best effect, but because of the large number of pulse valves and blowing pipes, there are defects such as easy failure, and the dust is flushed to the adjacent bag when cleaning the dust.

[0003] The designer of this patent proposed a mechanical dust removal scheme with ideal effect in the patent application with the application number of 2009101350321 and the name of the mechanical dust removal bag filter. The defect is that compressed air is required
