Abstract

A reinforced folding filter cylinder belongs to the field of industrial dust removal. The problem that the folded filter cylinder is not deformed in the use process after the length of the folded filter cylinder is lengthened is effectively solved. The filter cartridge comprises a filter material, a sealing bottom, a sealing head and a binding band, wherein the lower end of the filter material is arranged on the sealing bottom, and the upper end of the filter material is arranged on the sealing head; the bandage is fixed on the filter material, the top ends of the filter material folds are welded or bonded with the bandage, the distance between every two adjacent folds on the filter material is uniformly distributed, and the bandage divides the filter material into a plurality of lattice sections. The filter drum increases the effective filtering area and reduces the effective filtering area, and solves the problem that the folding filter drum is easy to deform, thereby prolonging the service life of the folding filter drum.

Description

Reinforced folding filter cylinder

Technical Field

Belongs to the field of environmental protection and industrial dedusting.

Background

Compared with a common filter bag, the folding filter cartridge has the characteristics of large effective filtering area, low pressure difference, low discharge, small volume, long service life and the like, and becomes the development direction of industrial dust collectors.

Along with the restriction of environmental protection dilatation transformation project place, the filter area requirement on folding the section of thick bamboo increases to the length of folding section of thick bamboo is also done more and more long. Therefore, in the operation process of the dust remover equipment, the folding filter cylinder can be quickly deformed along with the ash requesting of each pulse blowing, so that the ash removal is difficult, the pressure difference is increased, the consumption of compressed air is increased, and the service life of the folding filter cylinder is shortened.

When the folding filter cylinder is short, due to the support and fixation of the inner net and the strength of the filter material, the folding filter material can not deform during pulse back blowing of the dust remover, so that the dust cleaning effect can not be influenced, and the service life of the filter cylinder can not be influenced. When the folding filter cylinder is longer, the middle part of the filter cylinder can expand and deform along with the increase of the blowing times, so that the ash removal difficulty is higher and higher, compressed air required by the ash removal is more and more, meanwhile, the middle part of the filter cylinder is more and more easily attached together due to the increase of the length, the effective filtering area of the filter cylinder is further reduced, the using effect is influenced, and the service life is also shortened.

SUMMERY OF THE UTILITY MODEL

The reinforced folding filter cartridge is a special folding filter cartridge structure which is adopted for realizing that the folding filter cartridge is not deformed in the using process after the length of the folding filter cartridge is lengthened.

A reinforced folding filter cylinder comprises a filter material 1, a back cover 2, a seal head 3 and a binding band 4, wherein the lower end of the filter material 1 is arranged on the back cover 2, and the upper end of the filter material 1 is arranged on the seal head 3; the binding belt 4 is fixed on the filter material 1, and the top of the pleat of the filter material 1 is welded or bonded with the binding belt 4.

The space of each fold on the filter material 1 is uniformly distributed.

The binding bands 4 divide the filter material 1 into 2 or more than 2 lattice sections.

A binding band technology for folding filter cylinders divides a filter material 1 into uniform small sections through binding bands 4 according to the length of the filter cylinders. Each binding belt is welded with the top end of each fold of the folded filter cylinder in a hot melting welding and special sizing material bonding mode, so that the space between every two folds is uniformly distributed, and the effective filtering area of the folded filter cylinder is ensured. Simultaneously, every bandage divide into even segment to filter media 1 and tightly fixes, has reduced the deformation rate of filter media when the jetting, can not take place the condition of expansion deformation after long-time the use to the life of folding a section of thick bamboo has been guaranteed.

The technical effects are as follows: the utility model discloses an increased a bandage technique of straining a section of thick bamboo on the basis of straining a section of thick bamboo at present folding to effective filter area who has solved after folding section of thick bamboo length increase reduces, the easy deformation scheduling problem of folding section of thick bamboo, thereby has guaranteed the folding life who strains a section of thick bamboo.
