Embodiment Construction
[0029]Refer to 1-3, including the inspection port 3 arranged on the top of the bag filter clean air chamber 1, and the cover plate 2 arranged above the inspection port. The cover plate is divided into two symmetrical square sub-cover plates. The cover plates are all movably installed on the same rotating shaft 11, and can rotate clockwise or counterclockwise in the horizontal plane around the rotating shaft respectively; side sealing rubber strips 12 are installed on the adjacent sides of the two sub cover plates; The bottom of the cover plate is provided with a guide groove 7 in the area corresponding to the edge of the inspection port 3. The guide groove is divided into upper and lower layers. The upper layer is equipped with a spring 6 for squeezing the balls. A movable support plate 10 is arranged between the spring and the cover plate; a layer of sealing rubber strip 8 is arranged on the peripheral area of the guide groove on the cover plate, and the height of the sealin...

The invention relates to a bag type dedustor overhaul device and discloses a rotary square double-leaf access door. The rotary square double-leaf access door comprises an overhaul opening which is formed in the top of a gas purifying chamber of a bag type dedustor, a cover plate which is arranged above the overhaul opening, wherein the cover plate is divided into two sub cover plates which are in a left and right symmetric manner, and the two sub cover plates are movably installed on a same rotary shaft and can respectively rotate clockwise or anticlockwise in the horizontal plane around the rotary shaft; side sealing rubber strips are installed on the edges adjacent to the two sub cover plates; a guide slot is formed in a region, corresponding to the edge of the overhaul opening, at the bottom of each sub cover plate, and the guide slots are divided into upper and lower layers; the upper layer is provided with a spring for extruding balls while the lower layer is provided with the balls which are consistent with the guide slots in diameter, and a movable supporting plate is arranged between the balls and the spring. The device provided by the invention can be used for solving the problem that a top access door of an existing bag type dedustor is poor in leakproofness and the cover plate is hard to open, and has the characteristics of simplicity and convenience in operation, good airtightness 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 ...
