Embodiment Construction

[0028] Referring to 1-3, the sliding inspection door with balls of the present invention includes an inspection port 3 arranged on the top of the bag filter clean air chamber 1, a cover plate 2 arranged above the inspection port, and two rows and The cover plate 2 has parallel guide grooves 7 that match each other. The guide grooves are divided into upper and lower layers. The upper layer is equipped with balls 5 with the same diameter as the guide groove width, and the lower layer is installed with springs 6 for supporting the balls. The support plate 10; the periphery of the guide groove is provided with a layer of sealing rubber strip 8, and the height of the sealing rubber strip is lower than the balance height when the full weight of the cover plate 2 is pressed on the spring; the length of the guide groove is 1.5 times greater than the width of the cover plate.

[0029] A handle 4 is arranged above the cover plate 2 . The vertical section of the sealing rubber strip 8 is...

Abstract

The invention relates to an overhauling device of a bag type dust collector and discloses a sliding access door with balls. The sliding access door comprises an access hole formed in the top of a gas purifying chamber of the bag type dust collector and a cover board arranged above the access hole; the sliding access door is characterized in that two rows of parallel guide grooves matched with the cover board mutually are formed nearby the access hole, the guide grooves are divided into an upper layer and a lower layer, the upper layer is provided with the balls of which the diameter is consistent to the width of the guide groove, the lower layer is provided with a spring for supporting the balls, a movable bearing plate is arranged between the balls and the springs, sealing rubber strip layers are arranged at the periphery of the guide grooves, and the height of the sealing rubber strip is lower than the balance height of the springs on which the total weight of the cover board are applied. The sliding access door with the balls solves the problem that the access door at the top of an existing bag type dust collector is used inconveniently, and has the characteristics of convenience in operation, low cost 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 ...
