Description

Technical Field

[0001] The utility model relates to the technical field of needle-punched felt filter bags, in particular to a polyester three-proof needle-punched felt filter bag. Background Art

[0002] Polyester three-proof needle felt filter bag is a dust removal cloth bag with three major protective functions of waterproof, oil-proof and anti-static, so it is called three-proof needle felt filter bag. This filter bag is made of high-quality polyester fiber, so it is resistant to acid, alkali, and hydrolysis, and has low running resistance, which can save unnecessary energy. The polyester three-proof needle felt filter bag has a small pore size, high porosity, smooth surface treatment, and has the surface filtration effect of coated filter materials. Polyester three-proof needle felt filter bag is widely used in steel mills and other industrial dust removal fields. The connection between the existing polyester three-proof needle felt filter bag and the equipment cannot be sealed and is prone to air leakage.

[0003] The defects of existing three-proof needle felt filter bags are:

[0004] Patent document CN211963408U discloses a polyester triple-proof coated needle-punched felt filter bag fabric, which discloses that "when the filter bag made of this fabric is in use, the filtered liquid or gas first passes through the first filter layer, and then passes through the second filter layer. The first filter layer first filters the liquid or gas once, and when passing through the second filter layer, the second filter layer filters the liquid or gas a second time. One filter bag can filter the gas or liquid twice, which is beneficial to improving the filtration efficiency of the filter bag and facilitating reducing the number of filter bags installed. The first wear-resistant layer and the second wear-resistant layer greatly improve the wear resistance, impact resistance and tear resistance of the fabric, which is beneficial to increasing the service life of the filter bag made of the fabric". It does not take into account the problem that the connection between the polyester triple-proof needle-punched felt filter bag and the equipment cannot be sealed and is prone to air leakage.

[0005] In view of this, it is necessary to develop a polyester three-proof needle-punched felt filter bag, and then the connection between the polyester three-proof needle-punched felt filter bag and the equipment is sealed to prevent air leakage. Utility Model Content
