Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and particularly relates to a dust removal device for a workshop. Background Art

[0002] Dust removal equipment refers to equipment that separates dust from flue gas, also known as a dust collector. Dust removal equipment utilizes the dust removal water pipe and compressed air pipeline underground, adds a certain additive to water, introduces air pressure, and through special equipment, completes a series of technological processes to generate foam, which is sprayed onto the dust source through a distributor and a spray head support assembly. Dust removal technologies generally include mechanical dust removal, wet dust removal, electrostatic dust removal, and bag dust removal. Among them, bag dust removal equipment is a high-efficiency bag dust collector, which is a dry dust filtering device. It is suitable for capturing fine, dry, and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag dust removal equipment, dust particles with large particle size and high specific gravity settle down due to the action of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified.

[0039] The implementation principle of the dust removal device for workshops of the present invention is as follows: when dust in the workshop needs to be removed, the dust enters the dust collector 1 from the air inlet at the bottom of the dust collector 1, enters the bottom of the filter bag 2, is removed in the filter bag 2, passes through the top of the filter bag 2, and is discharged from the exhaust port of the dust collector 1. Iron filings in the dust entering the dust collector 1 are adsorbed by the magnetic rod 9, and the iron filings are collected on the magnetic rod 9. After the magnetic rod 9 has been used for a period of time, the magnetic rod 9 is pulled out of the dust collector 1, and the iron filings on the magnetic rod 9 are cleaned; When the filter bag 2 needs to be disassembled and replaced after being used for a period of time, the motor is started to drive the rotating rod 531 to rotate, and the rotating rod 531 drives the rotating disk 532 to rotate, and the rotating disk 532 reels the lifting rope 52, and the lifting rope 52 drives the clamping ring 51 to rise, and the clamping ring 51 drives the lifting platform 4 to rise, and the lifting platform 4 drives the filter bag 2 to rise, and the multiple cage rings 32 and the connecting rope 31 are retracted. When the cage ring 32 and the connecting rope 31 are retracted to the mounting plate 6, the screw rod 722 is rotated to drive the clamping ring 71 to rise along the supporting plate 721. At this time, the clamping ring 71 unlocks the top of the filter bag 2, and the filter bag 2 is pulled out of the cage ring 32, and the disassembly operation of the filter bag 2 is completed; After the filter bag 2 is replaced, it is installed. First, the filter bag 2 is inserted into the cage ring 32, and one end of the filter bag 2 is passed upward around the cage ring 32 and placed between the mounting plate 6 and the clamping ring 71. Then, the screw rod 722 is rotated to drive the clamping ring 71 to move up and down and slide along the support plate 721. When the clamping ring 71 descends, it cooperates with the mounting plate 6 to squeeze and lock the top of the filter bag 2. At this time, the motor is started to drive the rotating rod 531 to rotate, and the rotating rod 531 drives the rotating disk 532 to rotate. The rotating disk 532 unwinds the lifting rope 52, and the lifting rope 52 drives the clamping ring 51 to descend. The lifting platform 4 descends at the same time, and the lifting platform 4 drives the filter bag 2 to descend, and unfolds multiple cage rings 32 and connecting ropes 31. When the cage ring 32 and the connecting rope 31 are fully unfolded, the installation of the filter bag 2 is completed.
