Description

Technical Field

[0001] The invention relates to the field of sewage pool deodorization devices, in particular to a sliding deodorization cover. Background Art

[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 or even fifty or sixty meters. Rotating scrapers are installed in the sewage pools. When the scrapers are working, the sewage pools will produce a lot of odor. In order to effectively reduce the emission and discharge of odorous gases, the odor pollution sources in the sewage plant should be closed and directly collected within the smallest range. The cover plate erected on the sewage pool is an important part of the odor sealing and collection in the deodorization system engineering.

[0003] The sewage pool cover currently used is a whole flat plate, generally made of reinforced concrete or steel plate. However, reinforced concrete plate and steel plate are heavy, inconvenient for construction and maintenance, and the span they can be used for is limited. The sewage pool cover cannot be sealed with the sewage pool when closed, and cannot slide reliably and conveniently when opened, wasting a lot of manpower and material resources.

[0004] The document with patent application number 201620330594.7 discloses a "sewage pool deodorizing hood", which adopts a high-strength fiberglass hood without metal frame support. The cross-section of the high-strength fiberglass hood is a large-span arch shape, and the longitudinal section is a number of continuous small-span arch shapes to form a bidirectional arch structure; the two lateral ends of the high-strength fiberglass hood extend outward to form a pool body connecting flange, which is fixedly connected to the pool body. Therefore, the deodorizing hood of this patent is fixed or immovable, with very poor flexibility, which is not convenient for cleaning and maintenance of the sewage pool. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a sliding deodorizing hood. After using the deodorizing hood, the movable cover plate slides smoothly and reliably, does not deviate, has a small shaking amplitude, and has strong stability. The sewage pool is well isolated from the outside, and odor leakage is prevented, thereby ensuring safety.

[0008] In order to solve the technical problem, the further technical solution adopted by the present invention is:

[0009] Furthermore, track mechanisms are provided on both outer edges of the sewage pool, and the track mechanisms are L-shaped double-track tracks. The upper end of the L-shaped double-track track is provided with a folded edge facing the side of the movable cover plate, and the folded edge is in conflict with the sealing soft rubber. The lower end of the L-shaped double-track track is respectively fixedly connected with the outer edge of the fixed cover plate and the outer edge of the sewage pool by bolts; the upper surface of the lower end of the L-shaped double-track track is provided with a stainless steel bottom plate, and the upper surface of the stainless steel bottom plate is provided with a stainless steel guide rail with strip-shaped protrusions.

[0010] Furthermore, the sliding mechanism includes a vertically arranged U-shaped steel beam, a support seat located below the U-shaped steel beam, rollers with both ends fixed on both sides of the support seat, nylon rollers that are sleeved on the rollers and vertically arranged, transversely arranged stainless steel legs, a rotating shaft with both ends fixed on both sides of the stainless steel legs, and a stainless steel bearing that is sleeved on the rotating shaft and transversely arranged, and the stainless steel legs are transversely fixed on the outer surface of the U-shaped steel beam.

[0011] Furthermore, the vertically arranged nylon roller is a concave roller, and the transversely arranged stainless steel bearing is a flat roller. The concave roller matches and conflicts with the raised stainless steel guide rail at the lower end of the L-shaped double-track track, and the wheel surface of the flat roller conflicts with the inner surface of the upper end of the L-shaped double-track track.

[0012] Furthermore, one end of the sealing soft rubber is fixed to the upper surface of the outer edge of the movable cover plate, and the other end of the sealing soft rubber protrudes outward and matches the folded edge of the upper end of the L-shaped double-track track.

[0013] Furthermore, a pressure strip is provided on the upper surface of one end of the sealing soft rubber close to the movable cover plate, and the pressure strip and the sealing soft rubber are fixed to the outer edge of the U-shaped steel beam by rivets.

[0014] Furthermore, the pressure strip is a stainless steel plate.

[0015] Furthermore, the stainless steel guide rail is a square steel guide rail.

[0016] Furthermore, the total span of the cross-sectional direction of the movable cover is 5-25 meters.

[0017] The beneficial effects of the present invention are:

[0018] 1. Both outer edges of the movable cover of the deodorizing cover of the present invention are provided with sliding mechanisms, which are composed of a vertically arranged U-shaped steel beam, a support seat located below the U-shaped steel beam, rollers fixed at both ends on both sides of the support seat, nylon rollers sleeved on the rollers and arranged vertically, horizontally arranged stainless steel legs, rotating shafts fixed at both ends on both sides of the stainless steel legs, and stainless steel bearings sleeved on the rotating shafts and arranged horizontally, which can make the movable cover slide back and forth on the outer edge of the sewage pool, the horizontal stainless steel bearings can slide along the upper end of the L-shaped double-track track, and the vertical concave nylon rollers can slide along the stainless steel guide rails on the L-shaped double-track track, which can not only make the movable cover slide back and forth on the outer edge of the sewage pool, but also ensure that the movable cover can be stable, reliable, and not deviate, and the structural stability is strong, which is conducive to the sliding opening of the movable cover;

[0019] Second, a sealing soft rubber is provided between the movable cover plate of the present invention and the outer edge of the sewage pool, one end of the sealing soft rubber is fixed to the upper surface of the outer edge of the movable cover plate, the other end of the sealing soft rubber protrudes outward and matches the folded edge of the upper end of the L-shaped double-track track, a pressure strip is provided on the upper surface of one end of the sealing soft rubber close to the movable cover plate, and the pressure strip and the sealing soft rubber are fixed to the outer edge of the sewage pool by rivets.

[0020] The sewage pool is isolated from the outside, which prevents the smell in the sewage pool from leaking out, and prevents the maintenance personnel's feet, maintenance tools or foreign debris from getting stuck in the gap between the sewage pool and the movable cover, thus affecting normal operations. The structural stability is better;

[0021] 3. The vertically arranged nylon roller of the present invention is a concave roller, which is matched and collides with the raised stainless steel guide rail at the lower end of the L-shaped double-track track; the transversely arranged stainless steel bearing is a flat roller, which collides with the inner surface of the upper end of the L-shaped double-track track. The use of the concave roller can play a role in limiting and stabilizing the movable cover during the sliding process; the use of the flat roller can reduce the friction between the upper end of the L-shaped double-track track and alleviate the amplitude of the left and right shaking of the sliding cover during the sliding opening process.
