Problems solved by technology
Among them, the common problem of the thread structure is that it is difficult to ensure the coaxiality of the upper and lower filter bags during docking, which may easily 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. , the insufficient pre-tightening force will easily cause problems in sealing performance, and it is inconvenient to install and operate
The main problem of the flange structure is that in order to ensure the air tightness 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

The invention discloses a metal filter bag connecting device. The connector comprises a male connector, a female connector and an elastic sealing gasket, and the end, connected with the female connector, of the male connector is a connecting end. A plurality of protruding pieces are evenly distributed on the outer edge of the connecting end of the male connector in the circumferential direction atintervals. A plurality of concentric-square-shaped grooves capable of being clamped with the protruding pieces in a one-to-one correspondence manner are uniformly formed in the side wall of the connecting end of the female connector in the circumferential direction at intervals; and the groove opening of each clip-shaped groove is located in the end face of the side wall, close to the male connector, of the connecting end of the female connector, the directions of the clip-shaped grooves are consistent, and the elastic sealing gasket is arranged between the connecting end of the male connector and the connecting end of the female connector. The device has the advantages of being high in locking efficiency, high in coaxiality, capable of preventing fatigue failure after long-time use and good in sealing performance.
Description
technical field [0001] The invention relates to a docking device, in particular to a metal filter bag docking device and a docking method. Background technique [0002] Metal filter bags are widely used in coal chemical industry, metallurgy and other industries because of their high temperature resistance, corrosion resistance, recycling and many other advantages. 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 in the electric bag dust collector of the coal power industry. However, the large flue gas volume of coal-fired boilers determines that long filter bags (generally greater than 6 meters) must be used, otherwise the dust removal equipment will be huge and cannot be used industrially. Since the metal filter material cannot be folded, the filter material and bag cage of each section must be integrally welded and formed in the factory, and then transported to the site fo...
