Connecting system for dust removal cloth bag fixation

Abstract

The invention discloses a connecting system, and particularly relates to a connecting system for dust removal cloth bag fixation and belongs to the technical field of design and manufacture of subsidiary equipment for metallurgical production. The invention provides the connecting system for dust removal cloth bag fixation, which is firm in connection and is difficult to loosen and fall off in therunning process. The connecting system comprises a dust removal cloth bag and a fixed support chain and further comprises an elastic fast assembly component and an anti-loosening closed connection component; and the upper end of the elastic fast assembly component is connected with the fixed support chain, and the lower end of the elastic fast assembly component is movably connected with the dustremoval cloth bag through the anti-loosening closed connection component.

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
