Metal filter bag capable of being conveniently spliced and mounted

Abstract

The invention discloses a metal filter bag which is convenient for splicing and installation. It comprises an upper connector and a lower connector. Both the bottom of the inner wall of one side of the upper connector and the top of the inner wall of one side of the lower connector are provided with I-shaped connecting grooves. And the inner walls of the two I-shaped connecting grooves are sleeved with the same sealing ring, the bottom outer wall of the upper connector and the top outer wall of the lower connector are fixed with elastic pads by screws, and one part of the bottom outer wall of the upper connector There is a connecting groove on the side, and the same connecting ring is sleeved on one side of the outer wall of the upper connecting head and one side of the lower connecting head, and the connecting ring includes a left sub-connecting ring and a right sub-connecting ring. The invention can quickly splice two metal filter bags, which can be easily disassembled while ensuring the connection strength, can improve the coaxiality, can improve the sealing performance of the joint, and can eliminate part of the extrusion force while ensuring sufficient pre-tightening force , helps to protect product performance and prolong service life.

Description

technical field [0001] The invention relates to the technical field of metal filter bags, in particular to a metal filter bag which is convenient for splicing and installation. Background technique [0002] Metal filter bags are widely used in coal chemical industry, metallurgy and other industries because of their advantages such as high temperature resistance, corrosion resistance, and recyclability. With the rapid development of electric bag technology in the coal power industry, the industry has also begun to explore the use of metal filter bags It is used in the electric bag dust collector in the coal power industry. However, the large amount of flue gas in coal-fired boilers determines that long filter bags must be used. Otherwise, the dust removal equipment will be huge and cannot be applied industrially. In the field of filter bags, at present, The application of long chemical fiber filter bags has been very mature. The chemical fiber filter bags can be folded. Durin...

Problems solved by technology

[0002] Metal filter bags are widely used in coal chemical industry, metallurgy and other industries because of their advantages such as high temperature resistance, corrosion resistance, and recyclability. With the rapid development of electric bag technology in the coal power industry, the industry has also begun to explore the use of metal filter bags It is used in the electric bag dust collector in the coal power industry. However, the large amount of flue gas in coal-fired boilers determines that long filter bags must be used. Otherwise, the dust removal equipment will be huge and cannot be applied industrially. In the field of filter bags, at present, The application of long chemical fiber filter bags has been very mature. The chemical fiber filter bags can be folded. During installation, the chemical fiber filter bags and bag cages are installed separately, and then docked on site. The filter material and the bag cage must be integrally welded and formed in the factory, and then transported to the site for docking and installation. At present, the butt joint of metal filter bags mostly adopts a threaded butt joint structure or a flange butt joint structure. The coaxiality of the bag is difficult to ensure, and it is easy to cause the thread to be stuck or deformed during the tightening operation, and only two workers are required to manually rotate the bag body for docking, and the insufficient pre-tightening force will easily cause sealing problems, and It is inconvenient to install and operate. The main problem of the flange structure is that in order to ensure airtightness and uniform force during the butt joint, a large number of bolts need to be tightened, the operation time is long, and the work efficiency is low.
