A sliding access door

Abstract

The invention relates to a bag type dust collector overhaul device and discloses a 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 and is matched with the access hole. The sliding type access door is characterized in that two rows of parallel guide grooves matched with the cover plate are arranged beside the access hole; parallel slide blocks matched with the guide grooves are arranged below the cover plate, the guide grooves are divided into an upper layer for placing the slide blocks of the cover plate and a lower layer for mounting springs for supporting the slide blocks, and a movable smooth supporting plate is arranged between each slide block and each spring; the bottom of each slide block is a lubricating coating; the periphery of each guide groove is provided with a layer of sealing adhesive tape; the height of the sealing adhesive tape is smaller than the balance height when the whole cover plate is pressed on the springs; and the length of each guide groove is 1.5 times as much as the width of the cover plate. By using the 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 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 an inspection and repair device for a bag filter, in particular to an inspection door on the top of the bag filter. Background technique [0002] With the development of the industrial age, the bag filter has become a necessary equipment for many factories. The top of the bag filter is generally provided with an access door to facilitate the implementation of maintenance. The top access door of the bag filter includes an access opening on the top of the clean air chamber of the bag filter and a cover plate set above the access opening. At present, the top access doors of many bag filter manufacturers have a bolt, nut and cover plate structure. Use a wrench to tighten the nut of the cover plate, and then press the cover plate against the access door to prevent the access door from leaking. There are many inspection doors on the top of the dust collector, especially for large dust collectors in dozens of rooms. There are hundreds of...
