Description

A large-span aeration support for a biological treatment tank Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a large-span aeration support for a biological treatment tank. Background Technology

[0002] With the accelerating pace of urbanization, the requirements for environmental protection and ecological governance are becoming increasingly stringent. The continuous and stable operation of wastewater treatment plants and the achievement of water quality standards for discharge have become crucial components in safeguarding urban water environments and ensuring the ecological governance of watersheds. Biological treatment, as the core technological unit of wastewater treatment, plays a vital role in pollutant reduction. The aeration system, as the most important supporting infrastructure of biological treatment processes, directly affects the stable operation of the wastewater treatment biochemical system through parameters such as the effective supply of aeration volume, energy consumption, and dissolved oxygen transfer efficiency.

[0003] Currently, the span of biological treatment process structures in sewage treatment plants is basically up to 10m. When assembling aeration facilities in large-span tanks, a working platform needs to be added inside the tank to fix the aeration facilities. The working platform is a stainless steel bridge welded along the extension direction of the center line of the tank to provide support for the aeration frame, or an air inlet pipe and a condensate dewatering pipe are used as double-sided guide rails to achieve guidance and fixation. This method not only reduces the aeration area, but also increases the construction cost and construction difficulty.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a large-span aeration support for the biological treatment tank, in order to achieve a more practical purpose. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that addresses the issues of low aeration area, high construction cost, and high construction difficulty in assembling aeration facilities in large-span pools.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large-span aeration support for a biological treatment tank, comprising a support structure set at the bottom of the biological treatment tank and an air distribution pipe set on the support structure. An aeration pipe, an air inlet pipe, and a condensation and dehydration pipe are fixedly connected to the air distribution pipe. A lifting ring is fixedly connected to the top of the air inlet pipe. A counterweight square tube is fixedly connected to the air distribution pipe, and a support structure is provided on the counterweight square tube.

[0007] In a preferred embodiment, the support structure includes a fixed plate, a column, a support plate, and a pair of limiting frames. The fixed plate is bolted to the bottom of the biochemical tank. The column, support plate, and limiting frames are sequentially fixed to the top of the fixed plate. The pair of limiting frames are arranged in a V-shape, and the gas distribution pipe is arranged between the pair of limiting frames.

[0008] In a preferred embodiment, there are multiple aeration pipes, which are arranged along the length of the air distribution pipe.

[0009] In a preferred embodiment, a reinforcing rod is fixedly connected between the air distribution pipe and the air intake pipe.

[0010] In a preferred embodiment, a steel wire rope is provided on the lifting ring one.

[0011] In a preferred embodiment, the support structure includes a first support rod, a second support rod, a vertical rod, and a second lifting ring. One end of each of the first support rod, the second support rod, and the vertical rod is fixedly connected to the counterweight square tube. The other ends of the first support rod, the second support rod, and the vertical rod are fixedly connected together. The second lifting ring is fixedly connected between the first support rod and the second support rod.

[0012] In a preferred embodiment, a steel wire rope is provided on the second lifting ring, and a hanging rod for hooking the steel wire rope is fixedly connected to the top end of the air inlet pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The large-span aeration support for this biological treatment tank improves the aeration area within the tank by relocating the condensate dewatering pipe to the inlet pipe position near the air distribution pipe, installing a support structure at the bottom of the tank for supporting the air distribution pipe, and increasing the counterweight of the air distribution pipe by using counterweight square tubes. This saves construction costs and ensures aeration stability.

[0015] 2. The large-span aeration support for this biological treatment tank features a triangular support structure on a counterweight square tube and a lifting ring on the air inlet pipe. The support structure and the lifting ring provide two lifting points, which can be used in conjunction with a lifting device for stable lifting. Furthermore, the single-unit construction support structure provides support and limit for the lifting of the air distribution pipe. This allows for uninterrupted maintenance and lifting of the air distribution pipe, effectively shortening the maintenance cycle. Attached Figure Description

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Referring to Figures 1-5, this utility model provides a large-span aeration support for a biological treatment tank, including a support structure 7 installed at the bottom of the biological treatment tank and an air distribution pipe 1 installed on the support structure 7. The support structure 7 includes a fixing plate 71, a column 72, a support plate 73, and a pair of limiting frames 74. The fixing plate 71 is bolted to the bottom of the sewage biological treatment tank. The column 72, the support plate 73, and the limiting frames 74 are sequentially fixed to the top of the fixing plate 71. The pair of limiting frames 74 are arranged in a V-shape, and the air distribution pipe 1 is installed between the pair of limiting frames 74.

[0025] In this application, the lower part of the limiting frame 74 is vertically arranged, and the upper part of the limiting frame 74 is inclined outward. The fixing plate 71 is bolted to the bottom of the biochemical tank. The fixing of the column 72 and the support plate 73 on the fixing plate 71 can provide support for a pair of limiting frames 74. In this way, when the gas distribution pipe 1 is hoisted, the upper part of the limiting frame 74 is lowered by guiding the gas distribution pipe 1, so that the gas distribution pipe 1 can be effectively positioned between the corresponding lower parts of a pair of limiting frames 74.

[0026] Because the support structure 7 and the air distribution pipe 1 are connected by contact support, and because the support structure 7 is located below the air distribution pipe 1, this avoids the need to provide a stainless steel bridge in the length direction of the center of the pool and occupy the aeration area of ​​the pool when installing aeration facilities in traditional large-span biological tanks. Since there is no need to set up a stainless steel bridge to meet the support of the air distribution pipe 1, the length of the air distribution pipe 1 can be maximized and the aeration area of ​​the air distribution pipe 1 can be increased.

[0027] In this embodiment, an aeration pipe 2, an air inlet pipe 3, and a condensation and dehydration pipe 4 are fixedly connected to the air distribution pipe 1.

[0028] In this application, the condenser dehydration pipe 4 can be welded to the air inlet pipe 3 through a fastener, which can ensure the supporting strength of the condenser dehydration pipe 4. Since the traditional condenser dehydration pipe 4 and the air inlet pipe 3 are located on both sides of the air distribution pipe 1, this application changes the condenser dehydration pipe 4 to a position closer to the air inlet pipe 3. In this way, when installing aeration facilities in a large-span pool, the area occupied by the condenser dehydration pipe 4 in the pool 1 can be reduced, thereby improving the utilization rate of the pool aeration area.

[0029] Air is pumped into the air distribution pipe 1 through the air inlet pipe 3 by an existing blower or air compressor. The air forms tiny bubbles through the aeration pipe 2 and diffuses evenly. The bubbles can aerate the sewage in the biological treatment tank. When in use, the end of the air inlet pipe 3 away from the air distribution pipe 1 can be connected to the air delivery pipeline through a flange. The condensate dehydration pipe 4 installed on the air distribution pipe 1 mainly realizes the discharge of condensate through pressure difference and gravity. The specific discharge method of condensate through the condensate dehydration pipe 4 is a conventional technology and means, so it will not be described in detail here.

[0030] In this embodiment, there are multiple aeration pipes 2, which are arranged along the length of the air distribution pipe 1.

[0031] Because the air distribution pipe 1 in the large-span biological treatment tank has a length advantage, the multiple aeration pipes 2 installed on the air distribution pipe 1 can increase the aeration area.

[0032] In this embodiment, a reinforcing rod 11 is fixedly connected between the air distribution pipe 1 and the air intake pipe 3.

[0033] There are two reinforcing rods 11, which are arranged in a mirror image along the longitudinal center line of the air intake pipe 3. The reinforcing rods 11 can improve the connection strength between the air intake pipe 3 and the air distribution pipe 1.

[0034] A counterweight square tube 5 is fixedly connected to the air distribution pipe 1.

[0035] In this application, the counterweight square tube 5 can be increased by filling concrete to increase the counterweight of the air distribution pipe 1. In this way, the aeration pipe 2 on the air distribution pipe 1 can be stably placed in the biological treatment tank to perform aeration operations on sewage.

[0036] In this embodiment: a lifting ring 31 is fixedly connected to the top of the air intake pipe 3, and a steel wire rope 10 is provided on the lifting ring 31.

[0037] In this application, both ends of the steel wire rope 2 10 are knotted, and the steel wire rope 2 10 on the lifting ring 31 can provide a lifting point for the lifting device.

[0038] In this embodiment: a support structure 6 is provided on the counterweight square tube 5. The support structure 6 includes a first support rod 61, a second support rod 62, a vertical rod 63, and a second lifting ring 64. One end of the first support rod 61, the second support rod 62, and the vertical rod 63 are all fixedly connected to the counterweight square tube 5. The other ends of the first support rod 61, the second support rod 62, and the vertical rod 63 are all fixedly connected together. The second lifting ring 64 is fixedly connected between the first support rod 61 and the second support rod 62.

[0039] The struts 61 and 62 are set on the counterweight square tube 5 to form a triangular support structure. The upright 63 is fixed in the middle of the triangular support structure to improve the support strength. In this way, the triangular support structure can ensure the connection strength and balance of the lifting ring 64.

[0040] In this embodiment: a steel wire rope 8 is provided on the second lifting ring 64, and a hanging rod 9 for hooking the steel wire rope 8 is fixedly connected to the top of the air inlet pipe 3.

[0041] The hanging rod 9 is set in a "J" shape. The hanging rod 9 can serve as a temporary support for the steel wire rope 8. The steel wire rope 8 can provide another fulcrum for the lifting device. When the entire aeration support is lifted, the connection between the air inlet pipe 3 and the air delivery pipe is first disconnected. The lifting device is a crane. The lifting end of the crane can be equipped with a lifting balance bar. By connecting the steel wire rope 8 and the steel wire rope 10 to the lifting balance bar, the crane can lift the entire aeration support with high balance and stability. Similarly, when the crane controls the descent of the aeration support, when the air distribution pipe 1 is close to the position of the limiting frame 74, the limiting frame 74 can restrict the descent trajectory of the air distribution pipe 1, so as to provide a limit for the air distribution pipe 1 supported on the support plate 73.

[0042] In practical application, when dealing with a biological tank with a length and width of 20*20 meters, the length of the air distribution pipe 1 in this application is 8.7 meters and the width is 2.4 meters. The length of the aeration pipe 2 is 1 meter. The number of aeration pipes 2 set on the air distribution pipe 1 is 20. This specification layout can be better applied to large-span tanks and save construction costs.
