Coated dust-removal filter bag

Abstract

The invention discloses a coated dust-removal filter bag. The coated dust-removal filter bag comprises a filter cartridge, wherein reinforcing ribs are fixedly arranged on the inner wall of the filtercartridge at equal intervals, the diameter of the filter cartridge is reduced gradually from top to bottom, a plurality of fixing hoops are fixedly arranged in the filter cartridge from top to bottomat equal intervals, two mounting grooves are formed in two sides in each fixing hoop and are in clamping connection respectively with clamping blocks fixedly arranged on two sides of the outer wall of a mounting ring, the outer diameter of each mounting ring is smaller than the inner diameter of each fixing hoop, the bottoms of the mounting rings are fixedly connected with the tops of choking bags, a bag head sealing hoop is fixedly arranged at the top of the filter cartridge, a tightening rope is arranged in the middle of the bag head sealing hoop in a penetration manner, and two ends of thetightening rope are arranged out of the bag head sealing hoop. According to the coated dust-removal filter bag, the multiple choking bags are arranged in the filter cartridge, so that not only can air speed be reduced, impact of the air speed on the filter cartridge is weakened and the service life of the filter bag is guaranteed, but also to-be-filtered smoke can be filtered layer by layer, thedust removal efficiency of the filter bag is further increased, and the filter bag is convenient to mount.

Description

technical field [0001] The invention relates to a filter bag, in particular to a film-coated dust removal filter bag, which belongs to the technical field of dust removal auxiliary accessories. Background technique [0002] Bag filter is widely used in dust filtration in industrial and mining enterprises, such as coal-fired power plants, cement plants, steel plants, chemical plants, waste incineration and other industries, due to its high filtration accuracy, wide application range, and simple operation and maintenance. The filter bag of the bag filter is a key part in the operation of the equipment. Usually, the cylindrical filter bag is hung vertically in the dust collector. The fabric and design of the filter bag should be as efficient as possible, easy to remove dust and durable. The existing filter bag is only a simple cylindrical structure. When the blowing pipe blows air into the filter bag, the dust-cleaning airflow directly washes the filter bag, and the force on th...
