Description

Technical Field

[0001] This utility model relates to the field of sewage treatment, specifically a sliding fiberglass arched cover for sealing sewage tanks. Background Technology

[0002] Wastewater treatment plants often produce malodorous gases such as hydrogen sulfide, ammonia, and VOCs during wastewater treatment. These gases can pollute the environment and affect the health of plant operators and nearby residents. For rectangular sedimentation tanks and biological treatment tanks, concrete or stainless steel covers are commonly used to prevent the escape of malodorous gases and reduce environmental pollution. In areas requiring frequent maintenance and repair, or in situations with special requirements for corrosion resistance and structural strength, traditional concrete covers are heavy, have long construction periods, and are inconvenient to maintain. Stainless steel covers have poor corrosion resistance, are easily corroded by chemical media, and have a short service life. In contrast, fiberglass covers are lightweight, aesthetically pleasing, high-strength, compact, have excellent corrosion resistance, a long service life, low maintenance costs, and are easy to install and maintain. They have become the ideal choice for covering rectangular wastewater treatment tanks in wastewater treatment plants and are an important component of odor containment and collection systems.

[0003] Currently, FRP (fiberglass reinforced plastic) covers are typically attached to the walls of sewage tanks using bolts at both ends. This method lacks flexibility and hinders routine operation and maintenance, such as cleaning and servicing of equipment within the tank. Furthermore, FRP covers, used for enclosed collection and covering of sewage treatment tanks, are often used outdoors. Exposure to sunlight makes them prone to aging, and the high humidity inside the tanks leads to condensation. Additionally, gases such as hydrogen sulfide and ammonia emitted from the sewage accelerate corrosion, shortening the cover's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a sliding fiberglass arched cover for sealing sewage tanks, used for sealing and covering rectangular sedimentation tanks, biological treatment tanks and other sewage treatment facilities; it can effectively prevent the leakage and dispersion of odor or other harmful gases, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution adopted by this utility model is as follows:

[0006] A sliding fiberglass arched cover for sealing a sewage tank includes an arched cover assembly, a sliding component for moving the cover assembly, a flexible partition for sealing the sewage tank, a soft sealing plate, and a side plate.

[0007] The wastewater tank is sealed and covered by an arched cover assembly, flexible partitions, soft sealing plates, and side plates to prevent the leakage and escape of odors or other harmful gases. When the equipment inside the tank is to be repaired, the arched cover assembly can slide horizontally using sliding components set along the outer edges of both sides of the long side of the wastewater tank, facilitating the hoisting and maintenance of the equipment inside the tank.

[0008] The arched cover assembly includes a first arched cover and a second arched cover. The bottom edges of both ends of the first and second arched covers are fixedly connected to a first sliding mechanism and a second sliding mechanism, respectively, allowing them to slide. The height of the first arched cover is higher than that of the second arched cover. When the slidable arched cover is opened for easy maintenance, the second arched cover moves completely along the sliding assembly into the interior of the first arched cover. When the slidable cover is closed to seal the space within the pool, the first and second arched covers slide back to their original positions and are locked in place.

[0009] Both the first and second arched cover plates include a cover plate base, reinforcing ribs, flange edges, and a fixed base plate. The arched cover plates are manufactured using a one-time molding process, with flange edges along the width direction and fixed base plates on both sides. The length-to-width ratio is 5-6, the arch height is 0.12-0.15 times the span, the arc length is 5-12m, and 2-3 reinforcing ribs are provided, with a rib width and height of 60mm. The cover plate base thickness is 5-7mm, and the flange edges and fixed base plates are 10-12mm thick.

[0010] The sliding assembly includes a first sliding mechanism and a second sliding mechanism. The first sliding mechanism includes a support base fixed to the cover plate, pulley bearings fixed at both ends to the inner sides of the support base, an H-shaped pulley fitted onto the pulley bearings, and a square guide rail located below the pulleys and arranged along the outer side of the pool wall. The bottom edges of both ends of the first arched cover plate are respectively fixed to the support base of the first sliding mechanism, and move along the square guide rails located on the outer sides of the pool wall via the H-shaped pulleys. The second sliding mechanism includes a support base fixed to the cover plate, pulley bearings fixed at both ends to the inner sides of the support base, a flat pulley fitted onto the pulley bearings, and a U-shaped guide rail located below the pulleys and arranged along the outer side of the pool wall. The bottom edges of both ends of the second arched cover plate are respectively fixed to the support base of the second sliding mechanism, and move along the U-shaped guide rails located on the inner sides of the pool wall via the flat pulleys; the guide rails are fixed to the pool wall by fixing angle irons and expansion bolts.

[0011] Furthermore, by sealing the gaps and sliding components of the sewage tank with a flexible partition, one end of the PVC soft curtain is fixed to the edge of the arched cover plate with a pressure strip and self-tapping screws, and the other end hangs down naturally to the edge of the sewage tank. In this way, when the cover plate is spliced ​​to form an arched top to seal the sewage tank, the flexible partition plays the role of sealing and isolating the inner and outer spaces.

[0012] Furthermore, a soft sealing plate is used to seal the adjacent cover plates. One end of the PVC soft plate is fixed to the upper surface of the outer edge of the second arched cover plate by an aluminum alloy pressure strip and a self-tapping screw, while the other end hangs down naturally to the first arched cover plate and matches the edge flange of the second arched cover plate.

[0013] Furthermore, the arched cover and the edge of the sewage tank are sealed by side plates. These side plates are arc-shaped, with an arc consistent with the curvature of the second arched cover. The length of their bottom edge is equal to the span of the second arched cover. The arc-shaped edge is fixedly connected to the second arched cover located at the short edge of the sewage tank. The fixed connection employs one of two methods: integral molding or bolted flange fixing. A soft sealing strip is provided at the bottom edge to seal the gaps in the sewage tank. An observation port is provided on the side plate to allow operators to observe the internal condition of the sewage tank.

[0014] Furthermore, the arched cover assembly and side panels are all made of fiberglass, consisting of an outer surface layer, a reinforcing layer, and an inner surface layer. The outer surface layer uses phthalic resin with 0.1-0.2% added UV stabilizer to enhance anti-aging and UV resistance, with a thickness >0.2mm. The middle layer uses phthalic unsaturated polyester resin as the matrix and alkali-free untwisted fiberglass woven fabric as reinforcement to enhance load-bearing capacity, with a thickness of 5-6mm. The inner surface layer uses vinyl ester resin with 1%-3% added water-resistant agent to enhance corrosion resistance, with a thickness >0.2mm.

The arched cover body is made of one-piece molded fiberglass material, which has good strength, light weight, compact structure, excellent corrosion resistance, strong weather resistance and long service life, and is more suitable for use as a cover for sealing sewage tanks.

[0017] (2) The present invention provides a sliding fiberglass arched cover for sealing sewage tanks.
