Sliding type deodorization cover

Abstract

The invention discloses a sliding type deodorization cover. The deodorization cover comprises a fixed cover plate which is in an arch shape and stretches across the cross section of a sewage tank anda movable cover plate which is in an arch shape, is positioned above the fixed cover plate and stretches across the cross section of the sewage tank; the left side and the right side of the fixed cover plate are each provided with a fixing piece, and the left fixing piece and the right fixing piece are connected with the left side and the right side of the sewage tank respectively; the outer edgesof the two sides of the movable cover plate are exposed out of the outer edges of the two sides of the fixed cover plate, sliding mechanisms are arranged on the outer edges of the two sides of the movable cover plate, each sliding mechanism mainly comprises a vertical nylon roller and a transverse stainless steel bearing, and the sliding mechanisms can enable the movable cover plate to slide backand forth on the outer edge of the sewage tank; and sealing flexible rubber is arranged between the movable cover plate and the outer edge of the sewage tank, and the sealing flexible rubber can enable the periphery of the movable cover plate to be isolated from the periphery of the sewage tank. According to the deodorization cover, the movable cover plate is stable and reliable in the sliding process, free of deviation, small in shaking amplitude and relatively high in stability, the sewage tank and the outside are good in isolation effect, odor is prevented from leaking outside, and the safety is guaranteed.

Description

technical field [0001] The invention relates to the field of deodorizing devices for sewage pools, in particular to a sliding deodorizing cover. Background technique [0002] Existing sewage treatment plants often build primary sedimentation sewage pools and secondary sedimentation sewage pools. The diameter of the sewage pools is more than ten meters to fifty or sixty meters. A rotating mud scraper is installed in the sewage pool. When the mud scraper is working, the sewage The pool will produce a lot of odor. In order to effectively reduce the emission and discharge of odor gas, the source of odor pollution in the sewage plant should be sealed and directly collected within the minimum range. Erecting the cover plate on the sewage tank is an important part of the odor sealing and collection in the deodorization system engineering. [0003] At present, the commonly used sewage tank cover is a whole flat plate, which is generally made of reinforced concrete or steel plate. H...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used sewage tank cover is a whole flat plate, which is generally made of reinforced concrete or steel plate. However, due to their bulkiness, reinforced concrete plates and steel plates are not convenient for construction and maintenance, and the available span is limited.

The cover plate of the sewage pool cannot be sealed with the sewage pool when it is closed, and can slide reliably and conveniently when it is opened, which wastes a lot of manpower and material resources

[0004] The document with the application patent number of 201620330594.7 discloses a "sewage pool deodorization cover", which adopts a high-strength fiberglass cover without metal skeleton support. It is a number of continuous small-span arched shapes to form a two-way arched structure; the lateral ends of the high-strength FRP cover extend outwards to form a pool body connecting flange, which is fixedly connected to the pool body. Therefore, the exception of the patent The smell cover is fixed or immovable, the flexibility is very poor, and it is not convenient for the cleaning and maintenance of the sewage pool
