Description

Technical Field

[0001] The utility model relates to the technical field of pleated filter cartridges, in particular to a high-temperature resistant metal pleated filter cartridge. Background Art

[0002] Metal filter cartridge is a special filter material. It is a porous filter material made of metal fiber or metal powder through pressing and sintering, and then welded into a filter cartridge. Metal filter cartridge has the characteristics of high temperature resistance, strong acid and alkali resistance, and has a certain degree of flexibility. It is an ideal high temperature flue gas dust removal material.

[0003] After a metal filter cartridge has been used for a period of time, it is necessary to clean it. Air-flushing cleaning is a common method of cleaning filter cartridges. It uses high-pressure airflow to remove dust or impurities on the filter cartridge. Since the metal filter cartridge itself has a cylindrical mesh structure, dust is easily accumulated at adjacent mesh openings, which is difficult to completely clean with high-pressure airflow, so improvements are needed. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a high temperature resistant metal pleated filter cartridge.

[0005] The above-mentioned technical objective of the utility model is achieved through the following technical solutions: a high-temperature resistant metal pleated filter cartridge, comprising a metal pleated filter cartridge body, a first connecting sleeve welded on the outer wall of the metal pleated filter cartridge body near the top thereof, a top cover is arranged on the top of the first connecting sleeve, the top cover is of an open design, a first connecting seat is fixed on the bottom of the top cover, the first connecting seat is located in the first connecting sleeve, a second connecting sleeve is welded on the outer wall of the metal pleated filter cartridge body near the bottom thereof, a bottom cover is arranged on the bottom of the second connecting sleeve, a second connecting seat is fixed on the top of the bottom cover, the second connecting seat is located in the second connecting sleeve, the diameter of the top cover is larger than the diameter of the bottom cover, an annular body is arranged on the outer wall of the metal pleated filter cartridge body, a brush is arranged on the inner wall of the annular body, the bristles of the brush are pressed against the outer wall of the metal pleated filter cartridge body, and a driving component for driving the annular body to move up and down is jointly arranged between the top cover and the bottom cover.

[0006] By adopting the above technical solution, the top cover of the metal pleated filter cartridge body is installed on the flower plate on the top of the dust removal box. Driven by the induced draft fan, the dust-containing high-temperature gas flows from the outside to the inside.
