Novel filter bag non-woven fabric hot melting structure

Abstract

The invention discloses a novel filter bag non-woven fabric hot melting structure. The structure comprises a bag type filter composed of a plurality of filter bag single bodies, an outer frame is arranged at the top of the bag type filter, each filter bag single body is formed by bonding two pieces of filter cloth, the two sides of the filter cloth are formed by hot melting through side bonding lines, and the lower sides of the filter cloth are formed by hot melting through lower bonding lines. Each filter cloth comprises an outer-layer non-woven fabric, a middle filter material layer and an inner-layer non-woven fabric, and a non-woven fabric strip is in press fit with the filter cloth on the two sides through ultrasonic hot pressing. The invention belongs to the technical field of filter structures. According to the novel filter bag non-woven fabric hot melting structure, the filter bag non-woven fabrics are bonded through ultrasonic hot melting, the bonding strength is higher than glue or sewing strength, the sealing performance is better, it is guaranteed that no leakage occurs in the filtering process, the filter bag structure is firm, and the outer walls of two adjacent filter bag single bodies are not in contact with each other under the action of airflow, so that the total area of all the filter bag single bodies can be fully utilized, the sufficient filter bag area is ensured, and the filtering speed is ensured.

Description

technical field [0001] The invention belongs to the technical field of filter structures, and specifically refers to a novel filter bag non-woven hot-melt structure. 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 collected. Retention, so that the gas is purified. [0003] The filter bag is a key part in 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 i...

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
