Problems solved by technology

[0004] The prior art solution above has the following defects: the dust removal mechanism in the above solution uses a filter bag to remove dust, and the dust adheres to the filter bag quickly and frequently. When there is too much dust attached to the outside of the filter bag, it is necessary to stop the gas dust removal. Dust is removed from the filter bag through the soot blowing mechanism, and the efficiency of dust removal is not high

Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] refer to figure 1 and figure 2, is a bag filter disclosed in the present invention, which includes a dust removal box 1, and a first channel 11 is fixed on one side of the dust removal box 1. An upper box body 2 is fixed above the dust removal box body 1 , and a second channel 22 is arranged above the upper box body 2 . The lower end of the dust removal box body 1 is funnel-shaped, and a dust discharge device 3 (prior art) is fixed at the bottom end. A horizontal fixing plate 12 is fixed inside the dust removal box 1, and a number of evenly distributed through holes 121 are arranged on the fixing plate 12 (the number of through holes 121 in this embodiment is set to 15). The through-hole 121 is provided with a dust-removing bag 13, and the opening of the dust-removing bag 13 is pressed against the fixed plate 12 by a mounting ring 153. plate 12. ...

Abstract

The invention relates to a bag filter, which includes a dust removal box, a horizontal fixing plate is arranged in the dust removal box, a number of dust removal bags are arranged under the fixing plate, and a dust reduction mechanism is arranged inside the dust removal bag. The dust reduction mechanism includes a fixed shaft inserted into the dust bag, a number of fan groups sleeved on the fixed shaft and rotatably connected with the fixed shaft, and a disturbance assembly arranged at the end of the fan group away from the fixed shaft. The bag flows up and down and rotates, and the disturbing component touches the inner wall of the dust bag, and a support frame fixed on a fixed shaft to support the dust bag is provided between two adjacent fan groups. The invention has the effect of efficiently utilizing wind energy to remove dust from the dust-removing bag while not stopping to remove dust from the gas, thereby improving work efficiency.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a bag filter. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and the filter function of the fiber fabric is used to filter the dusty gas. After filtering, when the dust-containing gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the effect of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter bag, the dust will be blocked. To purify the gas. [0003] The Chinese invention patent with the publication number CN110898547A discloses a bag dust collector, including: a box body, an air inlet pipe, an air outlet pipe, an air guiding mechanism, a dust removal mechanism and a soot blowing mechanism arranged in the box bod...
