Description

Bag-type dust collector access door sealing fastener

Technical Field

The utility model relates to a sack cleaner field especially relates to a sack cleaner access door sealing fastener.

Background

The bag-type dust collector is a dry dust filter. After the filter material is used for a period of time, due to the effects of screening, collision, detention, diffusion, static electricity and the like, a layer of dust is accumulated on the surface of the filter bag, the layer of dust is called as a primary layer, in the later movement process, the primary layer becomes a main filter layer of the filter material, and the filter material with larger meshes can also obtain higher filtering efficiency by virtue of the action of the primary layer. Along with the accumulation of dust on the surface of the filter material, the efficiency and the resistance of the dust remover are correspondingly increased, and when the pressure difference between two sides of the filter material is large, some fine dust particles attached to the filter material are extruded, so that the efficiency of the dust remover is reduced. In addition, the air volume of the dust removal system is significantly reduced due to the excessively high resistance of the dust remover. Therefore, the dust is removed in time after the resistance of the dust remover reaches a certain value. Therefore, the top access door needs to be opened frequently, the top access door belongs to a frequently-disassembled part, frequent disassembly easily causes damage of bolts, and the bolts in the prior art are fixedly welded, so that the bolts are inconvenient to replace when damaged.

Further, the access door includes the steel sheet, the folded plate is buckled by the steel sheet and is formed, the steel sheet inboard is equipped with the heat preservation, there is the interval in heat preservation lateral wall and folded plate, be equipped with sealed the pad between the interval. The arrangement of the heat insulation layer can avoid the dewing and corrosion of the steel plate.

Further, a spring washer is arranged between the nut and the pressing plate. Further increasing the compressive force.

Further, the section of the pressing plate is of an inverted U-shaped structure. For increased strength.

Furthermore, the top supporting stay between two adjacent access doors comprises a bottom plate and two side plates to form a U-shaped structure, and the pressing plate is of a linear structure; the top supporting stay at the position of a single access door comprises a bottom plate and a side plate to form a 7-shaped structure, and the pressing plate is also of the 7-shaped structure. The installation and the disassembly are easy.

The utility model has the advantages that:

1. the utility model discloses in through set up a plurality of take-up plates on the bottom plate of top brace, establish logical groove on the take-up plate and be used for the card bolt, so the bolt just conveniently takes out and inserts, and it is convenient to change.

2. The utility model discloses in set up the pressure strip cross-section into the intensity that the type of falling U structure increased the pressure strip.
