Description

A filter bag dust removal equipment

technical field

The invention relates to the technical field of dust removal equipment, in particular to a filter bag dust removal equipment.

Background technique

Filter bag dust removal equipment is widely used in environmental protection and industrial fields. The filter bag dust removal equipment structure in the prior art mainly includes a dust removal chamber, a dust gas chamber and an air supply device. A partition is arranged between the dust removal chamber and the dust gas chamber, and a suspension structure is arranged on the top of the dust removal chamber, and the filter bag is suspended on the suspension structure. The opening of the filter bag is arranged downward and passes through the partition to connect with the dust chamber. The gas to be dedusted is blown into the dust chamber by the air supply equipment, passes through the filter bag and then enters the dust chamber, and is discharged from the air outlet of the dust chamber. The basic principle is that when the gas passes through the dust filter bag, the characteristics of the dust removal fabric material block the solid impurities in the gas to achieve the dust removal effect. However, similar equipment in the prior art has the following disadvantages: with the increase of dust removal time, a large amount of solid impurities will be adsorbed on the inner surface of the filter bag, which will lead to a decrease in the ventilation performance of the filter bag and reduce the efficiency of dust removal.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

Referring to Fig. 1, a filter bag dedusting equipment includes a dust removal chamber 1, a dust gas chamber 2 and a filter bag 5, a partition 3 is arranged between the dust removal chamber 1 and the dust gas chamber 2, and the filter bag 5 is located in the partition The top of the plate 3 is installed in the dust removal chamber 1 through the suspension plate 4. The dust removal chamber 1 is provided with an air outlet 11, the dust chamber 2 is provided with an air inlet 21, and the partition 3 is provided with A through hole 31, the opening of the filter bag 5 faces downward and communicates with the air inlet 21 through the through hole 31, the lower end of the filter bag 5 is opened and sealed between the through holes 31, and the dust removal equipment also includes The vibrating mechanism is used to vibrate the fixed impurities attached to the filter bag. The vibrating mechanism includes a cylinder 6 and a cam 61. The cylinder end of the cylinder 6 is installed in the top wall of the dust removal chamber 1. The cylinder 6 The output shaft end is connected with the cam 61 and drives the cam 61 to rotate;

The left and right ends of the suspension plate 4 are installed in the dust removal chamber 1 through telescopic suspension rods 42, which are covered with return springs 43;

Further, a backing plate is provided between the cam 61 and the suspension plate 4 .

Furthermore, the bottom of the dust chamber 2 is set as a funnel structure 22 , and the bottom end of the funnel structure 22 is connected with a dust collection box 23 , and the dust collection box 23 is located below the air inlet 21 .

Still further, a buffer spring 51 is provided between the upper end of the filter bag 5 and the suspension plate 4 .

Further, the inner wall of the dust removal chamber 1 is respectively provided with steps on the left and right sides above the air outlet, the steps are located below the suspension plate 4, the telescopic suspension rod 42 is installed on the steps, the return spring 43 The upper end of the back-moving spring 43 touches against the suspension plate 4, and the lower end of the back-moving spring 43 touches against the step.
