Engraving machine dust pulse dust collector

Abstract

The invention relates to the technical field of dust collection equipment, and discloses an engraving machine dust pulse dust collector, which comprises a dust collector cavity, an air inlet is fixedly formed in the middle of one side of the dust collector cavity, and an air outlet is fixedly formed in the top of the other side of the dust collector cavity. A torsional spring structure is arrangedin filter cloth; the edge of the torsional spring is tightly attached to the filter cloth; before an air compressor is started and air is sprayed to the inner side of the filter cloth through a blowing pipe and a Venturi pipe; the torsional spring is rotated at first, a gap between every two sections of the torsion spring is reduced and clamped under the action of the rotating force; wood thornspenetrating into the filter cloth are clamped; after clamping, the torsional spring continues to rotate in the same direction, the wood thorns clamped in the gaps of the torsional spring can be pulledout of the filter cloth, and avoided is the situation that the wood thorns pricked into the filter cloth cannot be blown off in the air injection stage and are always located on the filter cloth, more dust is accumulated easily, the cleaning period of the filter cloth is shortened, and the workload of workers is increased.

Description

technical field [0001] The invention relates to the technical field of dust collection equipment, in particular to a pulse dust collector for engraving machine dust. Background technique [0002] Pulse bag filter is a relatively prosperous workshop dust removal equipment in the woodworking industry, such as: furniture factory workshop, wood factory workshop, wood panel factory workshop, door and window factory workshop, mahogany furniture workshop, etc. The reason why woodworking pulse bag filter is so popular is Because of its impressive overall performance, the dust removal equipment of the woodworking dust collector adopts high-pressure (0.5-0.7MPa) large-flow electromagnetic pulse valve to blow and clean the dust. It has the characteristics of large cleaning kinetic energy, high cleaning efficiency, and the air emission standard can be lower than the environmental protection requirements. [0003] Woodworking workshop dust removal equipment is suitable for: engraving ma...

AI Technical Summary

Problems solved by technology

[0004] It is to concentrate the wood dust scattered on each woodworking machine to a fixed point for centralized dust collection treatment. When the woodworking machine is working, there will be wood dust, and then it will be removed by the dust collector. This woodworking pulse bag dust collector is economical. However, there are often a large number of wood thorns inside the woodworking waste, and when these wood thorns are mixed with sawdust for cleaning, they often have the problem of piercing into the filter cloth, and the wood thorns on the filter cloth cannot be sprayed with air. It cannot be blown off during the stage, and it is easy to accumulate more dust on the filter cloth all the time, which shortens the cleaning cycle of the filter cloth and increases the workload of workers
