Mechanical-deashing bag-type dust collector

Abstract

The invention relates to a mechanical-deashing bag-type dust collector. The mechanical-deashing bag-type dust collector comprises a shell, a dust bucket, a cover plate, a horizontal separation plate and a plurality of vertical filter bags; the separation plate is arranged in the inner side of the shell and divides the inner side of the shell into a lower flow mixing chamber and an upper flow collection chamber; an air inlet is arranged on one side of the dust bucket, and an air outlet is arranged on one side of the shell; a flow guide plate in the flow mixing chamber is arranged on the dust bucket; the upper ends of the filter bags penetrate through the separation plate and are mounted on the separation plate; the separation plate is provided with sleeve rings which corresponds to filter bags coaxially one by one and sleeve the outside of the filter bags; rotating rings sleeve the lower ends of the filter bags, and are connected with the sleeve rings through a plurality of scrapping plates; rotating shafts are arranged on the rotating rings coaxially; the upper ends of the rotating shafts penetrate through the filter bags an are arranged above the separation plate; the rotating shafts are in sequential transmission connection though gear pairs; a coupling member which is arranged coaxially with any one of the rotating shafts is arranged on the cover plate; the upper end of anyone of rotating shafts is connected with the coupling member through a spline; a driving shaft above the cover plate is arranged on the coupling member.

Description

technical field [0001] The invention relates to the technical field of environmental protection dust removal devices, in particular to a mechanical dust removal type bag dust collector. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust, and uses the filtering effect of the filter material to filter the dusty gas to purify the gas; when the filter material is used for a period of time Finally, due to the effects of screening, collision, retention, diffusion, and static electricity, a layer of dust accumulates on the surface of the filter bag. This layer of dust is called the first layer. Layer, relying on the effect of the first layer, the filter material with larger mesh can also obtain higher filtration efficiency; therefore, with the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector will increase accordingly, when the filter mat...

Problems solved by technology

[0004] In view of the above situation, in order to make up for the technical deficiencies in the existing technology, the present invention provides a mechanical dust removal bag filter to solve the problem that the existing dust collector cannot effectively protect the first layer of dust when cleaning.
