Rapid positioning and connecting structure for metal filter bag flange and tubesheet

Abstract

The invention discloses a rapid positioning and connecting structure for a metal filter bag flange and a tubesheet, and relates to the technical field of environmental protection equipment. The metal filter bag penetrates through the middle part of the tubesheet, a connecting flange is arranged at the end part of the metal filter bag, a ceramic sealing ring is arranged between the connecting flange and the tubesheet, four butt-joint arc-shaped grooves are formed in the periphery of the connecting flange at equal angles, four circular grooves are formed in the periphery of the tubesheet at equal angles, and the connecting flange and the tubesheet are matched and correspondingly connected through the butt-joint arc-shaped grooves and the circular grooves. The metal filter bag is installed on the tubesheet, the connecting flange of the metal filter bag and the tubesheet are tightly attached and fixed through the ceramic sealing ring, the tight sealing effect can be effectively achieved when the metal filter bag is used under the high-pressure online working condition, the circular grooves are formed in the periphery of the connecting surface of the tubesheet at equal intervals, the plurality of butt-joint arc grooves are formed in the periphery of the connecting surface of the connecting flange of the metal filter bag at equal intervals, and the butt-joint arc grooves and the circular grooves are matched and correspond to each other and are quickly positioned and welded through quick positioning bolts.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a fast positioning connection structure between a metal filter bag flange and a flower plate. Background technique [0002] The filter bag is an important part of the bag or electric bag filter, which mainly uses the bag filter element made of metal fiber braid to capture the solid particles in the dusty gas through the filter mechanism. At present, most metal filter bags use metal fiber felt, powder sintered felt and other filter materials, which are machined into a cylindrical bag-like structure; a metal fiber O-ring is set between the filter bag and the filter bag, through the metal Fiber O-ring; between the filter bag and the flower plate, the filter bag is fixed in the flower plate hole inside the dust collector by adding a bead, and the filter bag bead is used to compress and seal. [0003] The existing filter bag is compressed and sealed by the ...

AI Technical Summary

Problems solved by technology

[0003] The existing filter bag is compressed and sealed by the filter bag bead. Therefore, in the process of connecting and installing the flower plate, the flange of the filter bag and the flower plate need to be connected and fixed by multiple quick positioning bolts, and then transported to the site for use. This installation operation method greatly reduces the installation efficiency and wastes a lot of manpower and financial resources. At the same time, under high-temperature online conditions, the connection between the filter bag flange and the flower plate is less sealed, and it is easy to Cause dust leakage, affecting normal process and production
