Anti-tearing dust collecting cloth bag of polyester needled felt support

Abstract

The invention belongs to the field of dust collecting bags, and particularly relates to an anti-tearing dust collecting bag of a polyester needled felt support, which comprises a bag body and ring frames positioned at the air inlet end and the air outlet end of the bag body, an input support is arranged on the ring frame at the air inlet end, and an output support is arranged on the ring frame at the air outlet end. An inner supporting mechanism for auxiliary connection is arranged in a clamping gap between the input support and the output support and a clamping gap between the output support and the annular frame, the stability of connection between the input support and the annular frame is improved through the inner supporting mechanism arranged in the gap between the support and the annular frame, and the situation that a bag body shakes and is torn due to internal and external influences in the gas transmission process is prevented; and the inner supporting mechanism includes an air bag piece, after the air bag piece is filled with air, external force borne by a first positioning frame, a second positioning frame and an annular frame can be dispersed and buffered, the supporting stability is improved, meanwhile, the tear resistance is improved, the inflated air bag piece can be used as a buffering structure, sealing of the connecting position can be achieved, and input air is prevented from leaking outwards along the connecting position.

Description

Technical field [0001] The present invention relates to the field of dust removal bags, and more particularly to a bumper-shaped dust removal bag of a polyester needle felt holder. Background technique [0002] Polyester needle felt is made of polyester fiber, polyester fiber, adhesive fiber, polypropylene fiber, etc., is made of acupuncture process, and the internal fibers of polyester needle felt felt, uniform, pore distribution, uniform fine fiber filter, porosity To 70%, it is used to make dust removal bags, but the support of the bag can only serve as the input and output terminals, and the bag body shaking in the internal and external effect during gas transmission, and the pocket of the input output is tear. If the hidden danger, the bag of tear can lead to leaching gas leakage, causing environmental pollution. Inventive content [0003] (1) Application [0004] In order to solve the technical problem in the background art, the present invention proposes a tear-filled dus...

AI Technical Summary

Problems solved by technology

[0002] Polyester needle felt is made of polyester fiber, polyester fiber, viscose fiber, polypropylene fiber, etc., through needle punching process. The fibers inside the polyester needle felt are staggered, and the pores are evenly distributed. Up to 70%, it is used to make dust-removing cloth bags, but the support structure of the cloth bag can only play the role of shaping the input and output ends. During the gas transmission process, the bag body shakes due to internal and external influences, and the bag body at the input and output ends is torn. Hidden danger, the tearing of the bag body will cause the transmission gas to leak out and cause environmental pollution
