Bag filter outer frame angle structure

Abstract

A bag filter outer frame knuckle structure, which is composed of a first beveled groove body and a second beveled groove body, both side walls of the first beveled groove body and the second beveled groove body are formed by a straight It consists of a vertical outer wall and an "L"-shaped inner wall. At the joint, protruding ears are provided on the beveled edges of the outer walls on both sides of the first beveled groove body, and the end faces of the "L"-shaped inner walls on both sides are opposite to themselves. The beveled edge is recessed backward, and the end faces of the "L"-shaped inner walls on both sides of the second beveled groove body are protruded forward relative to the beveled edge; The protruding ears on the cutting edge are correspondingly inserted into the gap formed by the beveled edges on both sides of the second beveled groove body and the protruding "L"-shaped inner wall, so as to form the knuckle structure of the outer frame of the bag filter. This solution solves the problems that there are gaps at the joints of the corners of the existing outer frame, the sealing performance is not good, the connection strength of the joints at the corners is low, and the resistance to twisting and deformation is poor.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to an outer frame knuckle structure formed by processing a metal plate used on a bag-type air filter. Background technique [0002] Bag filter is the most common air filter in industrial and civil air conditioning or ventilation systems, and its function is to filter dust particles in the air. The bag filter is mainly composed of a single filter bag, an inner frame and an outer frame, wherein the opening of the single filter bag is fixed on the inner frame to form a unit, and then multiple units are assembled on the outer frame to form a whole. The outer frame is mostly a rectangular frame structure, its function is to assemble multiple units, and the second is to install it into the installation frame of the air conditioner or ventilation system. Therefore, for the outer frame, providing sufficient installation strength is one of its main performances. [0003] At pres...
