The top cover 2 and the bottom cover 5 play a role in sealing the filter cylinder, meanwhile, the top cover 2 also facilitates the filter cylinder to be installed on the dust removal equipment, the strap is positioned on the inner side of the filter cylinder to play a role in fixing the folding distance, so that the folding distance of the filter cylinder is fixed and uniform, and the folding distance is fixed, so that the filter cylinder is attractive and uniform in filtering. The folding distance of uniform distribution is fixed at two ends in a folding way without using tooling fixtures (springs) at two ends of the folding filter material, so that the process of fixing the folding distance of the filter cylinder is simple and quick, and the labor is saved. The band is located between filter material 11 and filter screen 12, and the band has certain thickness, can separate certain distance to filter material 11 and filter screen 12, prevents that filter screen 12 from hugging closely filter material 11, and the filter function of filter material 11 is influenced in the wearing and tearing filter material 11.

The tie strip comprises a top end 8, an end 3 and a main body connecting the top end 8 and the end 3, wherein the top end 8 and the end 3 play a role of fixing the tie strip, and the main body is mainly used for fixing the internal folding distance of the filter cylinder and fixing the filter cylinder from the outer side. The filter cartridge is more firmly fixed and is not easy to scatter and deform, and the filtering is affected.

Filter material 11 includes top 9 and terminal 10, the top 9 of filter material 11 and the 8 fixed connection in top of band, the inner joint of band is called as, it is fixed with the one end of filter material 11 and the one end of band, make things convenient for the band to follow the fixed roll-over distance of filter material 11 circumference, the top 9 of filter material 11 and terminal 10 both ends are rolled over and are sealed and obtain a circular filter cartridge 4 of roll-over distance evenly distributed, accord with the design of a section of thick bamboo that strains that removes dust, it is the tube-shape to strain a section of thick bamboo, the folding interval of evenly is fixed with folding in a foldover ground, increase filter area, make full use of filter material 11 filters the dust.

The main part is including connecting main part one 7 on filter material 11 and extending to the outer main part two 6 of filter material 11, and main part one 7 is fixed in filter material section of thick bamboo 4 inboard, and the length of main part one 7 corresponds with the filter material section of thick bamboo 4 internal diameter, the main roll-over distance of fixing the filter material. The second main body 6 is located on the outer side of the filter cartridge 4, the length of the second main body 6 is larger than that of the first main body 7, the second main body 6 is wound around the outer side surface of the filter cartridge 4 for a circle and is fixedly connected with the tail end 3, the outer interface of the binding band is called, and the second main body is mainly used for fixing the filter cartridge and protecting the filter cartridge.

When straining a section of thick bamboo in the transportation, deposit, pile up the in-process, often receive the extrusion of great power, produce easily and warp, strain a section of thick bamboo and seal the easy scattering of department, strain a section of thick bamboo and also easily cause the filter media to damage or warp at the in-process of pulse blowback, main part two 6 along 4 surface winding a week of filter material section of thick bamboo and fixed with band end 3, consolidate filter material section of thick bamboo 4 for filter material section of thick bamboo 4 is difficult for scattering influence filtration process.

Filter material 11 is for being the folding stiff non-woven fabrics that draws together that sets up of W type, and the non-woven fabrics is more durable than the filter material of traditional filter paper material, and is more stiff and smooth than the filter material of filter cloth material, is suitable for to fold into the more section of thick bamboo of straining of number, and the material is stiff and smooth non-deformable. The non-woven fabrics are arranged in a W-shaped folding mode, the non-woven fabrics are folded and wound into a cylinder shape, and two ends of the non-woven fabrics are connected to form a stable cylinder-shaped structure. The filter surface of the filter cylinder is W-shaped, the filter area can be increased, the first main body 7 is fixedly connected with the folded W-shaped creases, and the folding distance is fixed, so that the distance between the creases of the non-woven fabric is equal, the filtering resistance can be reduced, and the ash removal is facilitated.

The fixed connection on the filter material barrel 4 and the folded seals at the two ends of the starting end 9 and the terminal end 10 of the filter material 11 are all welded by ultrasonic hot melting. Ultrasonic wave hot melt welding has replaced the rubber coating process, need not beat the rubber coating and has glued the bandage in the outside of filter media, and reuse rivet anchor meshbelt both ends are fixed, but direct hot melt welding has simplified the process, has saved the manual work, has improved production efficiency. Two main part twine filter material section of thick bamboo outside surface a week and carry out twice ultrasonic wave hot melt welding with the end, two main part and band end weld twice, indicate that there are two welding seams that are parallel to each other at the band outer kneck, weld twice and make the interface more firm, difficult fracture, the fixed section of thick bamboo of straining that can be better, the life of a section of thick bamboo is strained in the extension, does not strain the filter effect of a section of thick bamboo because of the not hard up influence of interface.
