Description

Technical Field

[0001] This utility model belongs to the field of environmental protection technology, specifically relating to a low-resistance, high-efficiency explosion-proof pulse bag filter. Background Technology

[0002] With increasingly stringent environmental protection requirements and stricter controls on dust emissions in industrial production processes, traditional dust removal equipment is no longer sufficient to meet the new environmental standards. There is a need to develop more efficient dust removal equipment to reduce dust emissions and minimize environmental pollution.

[0003] In certain industrial sectors, such as coal, chemical, metallurgy, and power, flammable and explosive dust is generated during production. Traditional dust removal equipment may cause dust explosions due to static electricity, friction, or other reasons. Therefore, it is necessary to develop dust removal equipment with explosion-proof functions to ensure the safety of the production process.

[0004] However, when the explosion-proof pulse bag filter is used for dust removal, the filter bags inside are easily covered with dust that is not easy to fall off. This can easily affect the subsequent gas passage, thus reducing the dust removal efficiency of the explosion-proof pulse bag filter.

[0005] This invention addresses the aforementioned problems by providing a low-resistance, high-efficiency device for explosion-proof pulse bag filters that can assist in cleaning dust from the sides of the filter bags. Utility Model Content

[0006] The purpose of this utility model is to provide an explosion-proof pulse bag filter with low resistance and high efficiency, in order to solve the problem mentioned in the background art that when the explosion-proof pulse bag filter with low resistance and high efficiency is used for dust removal, the internal filter bags are easily contaminated with dust and are not easy to remove, which can easily affect the subsequent gas passage and thus reduce the dust removal efficiency of the explosion-proof pulse bag filter with low resistance and high efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof pulse bag filter low-resistance high-efficiency device, comprising a pulse bag filter low-resistance high-efficiency device body and an internal filter bag disposed at a position inside the pulse bag filter low-resistance high-efficiency device body;

The movement of the internal piston can cause the side connecting pull-out box to draw or blow air into the internal telescopic connector, thereby compressing or extending the internal telescopic connector. The extension of the internal telescopic connector can cause the side connecting block to drive the scraping brush to move and scrape the built-in filter bag.

[0009] Preferably, a threaded through hole is provided at the middle position of the built-in piston, and a tension connecting rod is provided at the bottom position of the built-in piston. The tension connecting rod is connected to the built-in piston by threads.

A limit connecting block is provided on the side of the side connecting block, and a limit connecting groove is provided on the outside of the limit connecting block. An internal telescopic connector is provided at the upper end of the limit connecting block. A side connecting pull-out box is provided on the side of the pulse bag filter low-resistance high-efficiency device body.
