A Rotary Circular Double Page Inspection Door

Abstract

The invention relates to a bag type dust remover maintaining device and discloses a rotary type circular double-hinge access door. The rotary type circular double-hinge access door comprises an access hole formed in the top of a gas purifying chamber of a cloth bag dust remover, and a cover plate arranged above the access hole and matched with the access hole. The cover plate is divided into two semicircular sub cover plates which are in bilateral symmetry, the two sub cover plates are movably arranged on a same rotating shaft, and can respectively clockwise rotate or anticlockwise rotate around the rotating shaft in a horizontal plane. Side sealing rubber strips are arranged on adjacent edges of the two sub cover plates; arc-shaped guide grooves are formed in regions, corresponding to the edge of the access hole, at the bottoms of the sub cover plates, and are divided into an upper layer and a lower layer, a spring used for extruding balls is arranged at the upper layer of the groove, the balls the diameters of which are consistent with the widths of the guide grooves are arranged at the lower layer of the groove, and a movable supporting plate is arranged between the balls and the spring. According to the rotary type circular double-hinge access door, the problems of poor sealing and difficulty in opening the cover plate of the access door at the top of an existing bag type dust remover are solved; the rotary type circular double-hinge access door has the characteristics of simplicity and convenience in operation, good sealing and the like.

Description

technical field [0001] The invention relates to a maintenance device for a bag-type dust collector, in particular to a maintenance door at the top of the bag-type dust collector. Background technique [0002] With the development of the industrial age, the bag filter has become the necessary equipment for many factories. The top of the bag filter is generally equipped with an inspection door for inspection and maintenance. The top inspection door of the bag filter includes an inspection port on the top of the clean air chamber of the bag filter and a cover plate above the inspection port. At present, the top inspection door of many bag filter manufacturers is a bolt, nut and cover plate structure. Use a wrench to tighten the nuts of the cover plate, and then press the cover plate against the access door to prevent air leakage from the access door. There are many access doors on the top of the dust collector, especially hundreds of access doors on the top of the large dust ...
