Long metal filter bag butt joint structure, auxiliary installation tool and installation method thereof

Abstract

The invention relates to a long metal filter bag butt joint structure, an auxiliary installation tool and an installation method thereof. The long metal filter bag butt joint structure comprises a butt joint clamp pipe port and a butt joint sleeve pipe port in butt joint and respectively arranged in metal filter bag ports; an annular convex part in butt joint with an inner cavity of the butt joint sleeve pipe port is arranged on the end surface of the butt joint clamp pipe port; arc convex parts and arc concave parts are respectively arranged at the peripheries of the end surface edges of the butt joint clamp pipe port and the butt joint sleeve pipe port; annular grooves are respectively formed in the peripheries of the outer walls of the butt joint clamp pipe port and the butt joint sleeve pipe port; the arc concave parts communicate with the annular grooves; the arc concave parts include first arc grooves and second arc grooves for communicating with each other; the first arc grooves and the arc concave parts are distributed in an axial symmetry manner; the second arc grooves and the arc concave parts are distributed in a central symmetry manner; and the arc convex parts include first arc projections and second arc projections arranged up and down. Compared with the prior art, the long metal filter bag butt joint structure is excellent in tightness, simple and fast in disassembly and high in working efficiency.

Description

technical field [0001] The invention relates to a butt joint structure, in particular to a long metal filter bag butt joint structure and its auxiliary installation tool and installation method. Background technique [0002] The production process of ceramic industry, metallurgy, coal chemical industry, electric power generation and other fields all involve gas-solid separation operation. Gas-solid separation is mainly realized by gas filter devices such as filter bag dust collectors. Non-metallic woven cloth such as woven cloth and synthetic fiber is used as the filter material. The filter material is made into a bag shape through processing equipment, and then the filter bag is shaped with a cage-like bracket composed of metal rings and metal bars. The opening of the filter bag is provided with a The snap ring is used to fix the filter bag on the filter bag installation hole plate of the dust collector through the snap ring. However, most of the above-mentioned gases that...

Problems solved by technology

[0005] (1) The flange butt joint structure diagram is as follows figure 1 As shown, it means that a flange 7 is set at the port of the metal filter bag, and the two flanges 7 are fixed by bolts 8. The defect of the flange butt joint structure is that a large number of bolts 8 need to be tightened during the butt joint, and the working efficiency lower

[0006] (2) Threaded butt joint structure means that internal threads are set on the inner wall of one metal filter bag port, and external threads are set on the outer wall of the other metal filter bag port. The internal threads match the external threads. The defects of the threaded butt joint structure are: Sometimes it is difficult to ensure the coaxiality of the upper and lower filter bags, and it is easy to cause the threads to be stuck during the tightening operation, and only rely on manual rotation of the bag body for docking, and the insufficient pre-tightening force will easily cause problems in sealing
