The invention relates to a bag type dust collector overhaul device and discloses a cover plate sliding type access door comprising an access hole and a cover plate, wherein the access hole is formed in the top of an air purification chamber of a bag type dust collector; the cover plate is arranged above the access hole; guide grooves capable of guiding the cover plate to horizontally slide are formed between the access hole and the cover plate; each guide groove is internally provided with a ball layer and a spring layer; a movable supporting plate is also arranged between the ball layer and the spring layer; the periphery of each guide groove is provided with a layer of sealing adhesive tape; and the length value of each sealing adhesive tape is smaller than the balance height value relative to the top of the air purification chamber when the whole cover plate is pressed on springs. By using the cover plate sliding type access door, the problems of poor sealing performance and cover plate opening difficulty of the access door at the top of the existing bag type dust collector are solved; and the cover plate sliding type access door has the characteristics of simplicity and convenience in operation, good air tightness 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 ...
