With the rapid development of the heavy chemical industry (electric power, building materials, metallurgy, coal chemical industry and the like) in China, the problem of environmental pollution is more and more serious. The filter bag is a core component of a bag type dust removal system, and the performance of the filter bag determines the smoke dust treatment effect and the service life of the filter bag. The metal filter bag is also called as a metal fiber felt filter bag, and is gradually applied to high-temperature flue gas treatment in China due to the advantages of high temperature resistance, corrosion resistance, convenience in recovery and the like. In order to prevent the flue gas from being directly discharged into the air, the enterprise pollutes the environment and needs to spend great manpower and material resources to remove dust. In order to reduce the exhaust gas treatment cost of enterprises, long metal filter bags are the first choice of most enterprises at present. The metal filter bag is high-temperature resistant and corrosion resistant, can respond to the strategic call of national sustainable development, and can be recycled; the long metal filter bag is different from a common long chemical fiber filter bag, the long chemical fiber filter bag can be folded, so that the connection and installation of the long chemical fiber filter bag and a bag cage can be directly carried out on site, but the metal filter bag cannot be folded, so that each section of the metal filter bag needs to be integrally welded and formed in a manufacturing factory and then is transported to the site for installation, and the metal filter bags with the length of more than three meters need to be manufactured in sections for convenience of transportation. If the conventional joint of the filter screen is used, the defects that the sealing and the concentricity cannot meet the requirements due to the reason that the joint cannot be locked exist, and the design requirements cannot be met.

At present, the butt joint of metal filter bags generally adopts a flange and screw locking structure, the parts are heavy, the manufacturing and production cost is high, the assembly work efficiency is greatly reduced because more bolts need to be screwed, and the installation cost is improved.
