Connection system for fastening of dust bag

Abstract

The invention discloses a connection system, in particular discloses a connection system for fixing a dust bag, and belongs to the technical field of design and manufacture of auxiliary equipment for metallurgical production. A connection system for fixing the dust bag is provided that is firmly connected and is not easy to loosen and fall during operation. The connection system includes a dust bag and a fixed support chain, and the connection system also includes an elastic quick-fit assembly and an anti-off closure connection assembly, the upper end of the elastic quick-install assembly is connected to the fixed support chain, the The lower end of the elastic fast assembly is movably connected with the dust bag through the anti-off closure connection assembly.

Description

technical field [0001] The invention relates to a connection system, in particular to a connection system for fixing dust-removing cloth bags, and belongs to the technical field of design and manufacture of auxiliary equipment for metallurgical production. Background technique [0002] The filter bag of the blast furnace gas dry dust removal system, especially in the large bag backflush dust removal process, uses a suspension mechanism to fix the filter bag, and its structure includes a bag cap, semi-closed lifting lugs, chains, springs, and song hooks. The bag cap is stamped from a thin steel plate, and then galvanized on the surface, and is used for hanging and sealing the filter bag of the inner filter bag filter. The working resistance of the dust bag cap is mainly composed of the gravity of the mechanism itself and the force of the filter bag during backflushing cleaning. This kind of suspension mechanism has the following disadvantages: 1. The lifting lug of the bag c...

AI Technical Summary

Problems solved by technology

This kind of suspension mechanism has the following disadvantages: 1. The lifting lug of the bag cap is designed as a semi-closed structure. When the bag is installed, if the pre-tightening force is insufficient, after a certain period of operation, under the alternating action of continuous blowback and filtration, it will occur. The chain falls off from the lug of the bag cap, causing the bag to collapse; 2. The semi-closed lug is located on the inside of the bag cap without reinforcement design. When the bag is working, the pulling force is all concentrated on the joint between the bolt and the bag cap, which may easily cause the bag cap to crack ; 3. The lugs of the bag cap are connected by welding, which is easy to pull and crack; 4. The pressure spring is stressed by the hook, and the hook has no fixing mechanism in the spring. In the process of large bag dust removal, continuous filtration, reaction In the process of blowing alternately, the cloth bag will shake slightly due to the different forces in the filtration and back-blowing process, causing the song hook to move in the spring, which will easily cause mutual wear between the song hook and the spring

The above problems are the technical difficulties faced in the field of blast furnace gas large bag backflushing dust removal, which restricts the development of enterprise production
