Filter-bag non-woven fabric hot-melting structure

Abstract

The invention discloses a filter-bag non-woven fabric hot-melting structure. The filter-bag non-woven fabric hot-melting structure comprises a bag-type filter composed of a plurality of filter bag monomers; an outer frame framework is arranged on the periphery of the bag-type filter; a bag opening of each filter bag monomer is fixed with a supporting framework; the outer wall of each support framework is fixed on the inner wall of the outer frame framework; each filter bag monomer is formed by bonding two filter cloths; two sides of the two filter cloths are formed by hot melting through sidebonding wires; and the lower sides of the two filter cloths are formed by hot melting through lower bonding wires. The filter-bag non-woven fabric hot-melting structure has the advantages that the filter bag non-woven fabrics are bonded through ultrasonic hot melting, the bonding strength is higher than the bonding strength of gluing or sewing, the sealing performance is better, and leakage is avoided in a filtering process. A non-woven cloth strip is arranged on each filter bag monomer, so that when gas is blown into the filter bag monomer, the outer walls of the filter bags cannot be in contact with each other or be adhered with each other, and thus a sufficient filtering area of the filter bags is guaranteed.

Description

technical field [0001] The invention relates to the technical field of filter bags, in particular to a non-woven hot-melt structure of filter bags. Background technique [0002] The bag filter is a dry dust filter device, which is suitable for collecting fine, dry, non-fibrous dust. The gas is filtered. When the dusty gas enters the bag filter, the dust with large particles and specific gravity will settle down due to the effect of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust will be blocked. Leave to purify the gas. [0003] The filter bag is a key part of the operation of the bag filter. The fabric and design of the filter bag should be as efficient as possible, easy to remove dust and durable. In the pulse and air box pulse dust collector, the dust is attached to the outer surface of the filter bag. When the dusty gas passes through the dust collector, the dust is collected on the outer surface o...

Problems solved by technology

[0004] In order to ensure a sufficient filtering area and filtering effect in traditional bag filters, a plurality of filter bags arranged in parallel are generally arranged in the bag filter and bonded to each other. Gas filtration, but the adjacent filter bags are easy to fit each other, resulting in a waste of area between adjacent filter bags, resulting in a reduction in the filtration area and affecting the filtration effect. Moreover, the heat transfer filter bags generally use solvent The way of bonding, the sealing is poor, and the filtering quality is poor
