Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a sedimentation tank that avoids clogging of inclined tubes. Background Technology

[0002] Inclined tube sedimentation tanks are widely used in current wastewater treatment processes. An inclined tube sedimentation tank is a sedimentation tank with inclined tubes installed in the sedimentation zone. There are two assembly forms: inclined tubes and branch pipes. In the sedimentation zone of a horizontal or vertical flow sedimentation tank, a series of shallow sedimentation layers are divided by inclined parallel tubes or parallel pipes (sometimes honeycomb packing). The treated and settled sludge move and separate in each sedimentation layer. According to the direction of their mutual movement, there are three different separation methods: counter-current, co-current, and lateral flow. The space between each two parallel inclined plates (or inside the parallel pipe) is equivalent to a very shallow sedimentation tank. Its advantages are: (1) it utilizes the laminar flow principle, which improves the treatment capacity of the sedimentation tank; (2) it shortens the particle settling distance, thereby shortening the sedimentation time; (3) it increases the sedimentation area of ​​the sedimentation tank, thereby improving the treatment efficiency.

[0003] However, in practical engineering applications, while inclined tube sedimentation tanks have good initial sedimentation effects, long-term operation is very troublesome. This is especially true for sludge from the initial biological treatment process, which has a high sludge content and is sticky. The small space inside the inclined tubes makes it easy for sludge to adhere to the walls, leading to blockage problems after prolonged operation.

[0004] The prior art application with publication number CN204411789U uses an aeration pipe to clean the inclined pipe, but water backflows into the aeration pipe when it is not working, which is a problem that needs to be solved. Utility Model Content

[0033] Example 1

[0034] Reference Figures 1-6 This embodiment provides a sedimentation tank that avoids clogging of inclined tubes, including a shell 100. A vertical plate 101 is provided on one side of the shell 100 to divide the interior of the shell 100 into a water inlet zone 102 and a sedimentation zone 106. A through groove is provided below the vertical plate 101 to connect the water inlet zone 102 and the sedimentation zone 106. An ash collection trough 103 is provided at the bottom of the sedimentation zone 106. An inclined tube 104 is provided in the sedimentation zone 106. An aeration pipe 105 is provided below the inclined tube 104. The aeration pipe 105 includes a main pipe 105a and a pair of side pipes 105b provided on both sides of the main pipe 105a. The pair of side pipes 105b are connected to each other.

[0035] It should be noted that the water inlet zone 102 in this application can be equipped with a flocculation function using existing technology to treat particulate matter in the water in advance. The sedimentation principle of the sedimentation zone 106 adopts the inclined tube sedimentation of existing technology. The installation of the inclined tube 104 is not the main solution of this application, so existing technology can be used and will not be described in detail. Similarly, a water outlet is provided on the right side of the shell 100.

[0036] Silt and other sediments are deposited in the ash collection tank 103 and connected to the outside through pipelines. They are then transported out by gravity or pumping. The pipeline design is existing technology and will not be described in detail here.

[0037] Specifically, in order to solve the problem of mud and ash easily adhering to the inclined tube in the prior art, this application further improves the aeration tube based on the existing technology of setting aeration tube, increases the aeration area, and improves the structural stability of the aeration tube.

[0038] Multiple aeration holes 105c are arranged axially on both sides of the side pipe 105b. Gas is transported from the main pipe 105a to the side pipe 105b and then discharged from the aeration holes 105c on both sides of the side pipe 105b, thereby increasing the aeration area and improving cleaning efficiency.

[0039] One end of the side tube 105b is closed, and the other end is open and a ring plate 105d is provided. Connecting plates 105e are provided at both ends of the ring plate 105d.

[0040] The connecting plate 105e is provided with a through hole 105f. The paired side tubes 105b are connected to the connecting plate 105e by bolts, which ensures the connection stability of the side tubes 105b and avoids loosening, shaking and other situations caused by direct connection of a single side tube 105b to the main tube 105a.

[0041] It should be noted that a sealing ring is also provided at the opening of the side tube 105b to seal the connection between the side tube 105b and the air hole 105g.

[0042] Furthermore, air holes 105g are provided on both sides of the main pipe 105a, and a raised edge 105h is provided on the outside of the air hole 105g, which is embedded in the side pipe 105b.

[0043] A sealing element 107 is provided in the side tube 102. The sealing element 107 includes an end plate 107a and a spring 107b that connects the end plate 107a and the bottom of the side tube 102a.

[0044] A support rod 107c is provided on one side of the end plate 107a, and a sealing ring plug 107d is provided on the support rod 107c at the aeration hole 105c.

[0045] Specifically, when cleaning is required, air is supplied to the main pipe 105a, and the gas enters the side pipe 105b. Since the aeration holes 105c are all blocked by the sealing ring plugs 107d, the side pipe 105b is a closed space. Therefore, the sealing element 107 moves as a whole, compressing the spring 107b. The sealing ring plugs 107d are misaligned with the aeration holes 105c, and aeration begins.

[0046] After the process is completed, closing the air supply sealing component 107 will return it to its original position to prevent backflow.

[0047] It should be noted that the support rod 107c is a rigid rod structure, and the sealing ring plug 105d can be used to block the aeration hole 105c. It can withstand water pressure and prevent water from flowing back into the side pipe 102. Specifically, the sealing ring plug 105d may include a rigid annular plate for shaping and a soft rubber layer disposed on the outside of the rigid annular plate for sealing.

[0048] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
