Technical Field

[0001] This utility model relates to the field of inclined plate sedimentation tank technology, and in particular to an annular self-stabilizing inclined plate sedimentation tank. Background Technology

[0002] Inclined plate sedimentation tanks are high-efficiency solid-liquid separation devices based on shallow tank theory, widely used in the sedimentation stages of water supply treatment, municipal sewage treatment, and industrial wastewater treatment. Their working principle involves installing inclined parallel plates (or pipes) within the sedimentation tank, significantly improving sedimentation efficiency and treatment capacity.

[0003] Existing inclined plate sedimentation tanks require supports for each inclined plate, resulting in a complex structure. Furthermore, the support components for individual plates can trap sludge, leading to sludge accumulation and potential clogging. While the inclined plates have been improved by using inclined tubes, the reduced wall thickness makes the tube structure more prone to deformation. Additionally, the smaller tube diameter facilitates sludge accumulation, requiring regular sludge cleaning, which necessitates downtime and impacts production efficiency. Utility Model Content

The drive rod is axially arranged along the conical ring and passes through the innermost conical ring. The scraper is disposed at the bottom of the pool body and is connected to the drive rod. The output end of the drive source is connected to the drive rod.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-4 As shown, this utility model discloses an annular self-stabilizing inclined plate sedimentation tank, comprising: Pool body 1; Support frame 2, which is disposed inside the pool body 1 and is connected to the inner wall of the pool body 1; Multiple conical rings 3 are disposed on the support frame 2, and the large end of each conical ring 3 is connected to the support frame 2; the multiple conical rings 3 are nested together and coaxially arranged, and the distance between any two adjacent conical rings 3 is equal; the angle between the generatrix of each conical ring 3 and the central axis is the same.

[0019] In this invention, the support frame 2 is installed inside the pool body 1 to support the installation of the inclined plate. The inclined plate is composed of multiple conical rings 3. Compared with the support of a single inclined plate, the conical rings 3 have fewer fixed support points, which can effectively reduce the impact of the support frame 2 on sedimentation and prevent sludge accumulation. Secondly, the conical rings 3 have good structural stability, and different layers of conical rings 3 do not require support structures, further avoiding blockage caused by sludge accumulation.

[0020] Specifically, refer to Figures 2-3 As shown, the large end of each conical ring 3 is connected to the support frame 2, improving the stability of the conical ring 3 installation. Multiple conical rings 3 are nested sequentially from large to small, with the outer diameter of any two adjacent conical rings 3 being larger than the inner diameter, creating a contraction shape from the outside in. The distance between any two adjacent conical rings 3 is equal, ensuring that the width of the flow channel formed between each inclined plate is exactly the same, ensuring consistent sedimentation conditions in each flow channel, eliminating inefficiency bottlenecks, and preventing localized low efficiency from affecting the overall treatment. Secondly, the angle between the generatrix of each conical ring 3 and the central axis is consistent, meaning the inclination angle of each inclined plate flow channel is consistent, ensuring a uniform sedimentation rate and preventing localized blockages. Furthermore, the height of the multiple conical rings 3 in this invention is consistent, meaning the length of each flow channel is equal, ensuring equal sedimentation efficiency in each flow channel, eliminating localized failures, and further preventing localized blockages.

[0021] The inclined plate sedimentation tank of this utility model consists of multiple sets of topless conical ring-shaped inclined plates with diameters ranging from large to small. The structure of a single inclined plate is stable; no support structure is required between different layers of inclined plates, avoiding blockage caused by sludge accumulation; reducing the number of downtimes and improving production efficiency.

[0022] Furthermore, referring to Figure 3 As shown, the support frame 2 includes a pair of long rods 21 and a pair of short rods 22. The pair of long rods 21 are arranged parallel to each other inside the pool body 1, and both ends of the long rods 21 are connected to the inner wall of the pool body 1. The pair of short rods 22 are arranged on both sides of the two long rods 21, and the end of the short rod 22 away from the long rod 21 is connected to the inner wall of the pool body 1.

[0023] Specifically, the two long rods 21 are arranged in parallel, ensuring that the contact position between each conical ring 3 and the long rod 21 is the same, preventing different support points in local areas from affecting sedimentation efficiency. Secondly, the short rod 22 is arranged perpendicular to the long rod 21, that is, the angle between both sides of the short rod 22 and the long rod 21 is 90°, preventing the angle on one side from being too small, which would lead to dense support points and affect the sedimentation rate.

[0024] Furthermore, a pair of reinforcing rods 23 are arranged in parallel between the pair of long rods 21, and the long rods 21, short rods 22 and reinforcing rods 23 are all in the same plane.

[0025] Specifically, the reinforcing rod 23 enhances the overall strength of the support frame 2, ensuring the stability of the conical ring 3 installation. Secondly, the long rod 21, short rod 22, and reinforcing rod 23 are all in the same plane, ensuring consistent horizontal height for subsequent conical ring 3 installation. The equal length of the flow channels formed between each conical ring 3 ensures uniform sedimentation efficiency in each channel, preventing localized failures and further avoiding localized blockages.

[0026] Furthermore, it also includes a sludge scraping assembly 4, which includes a drive rod 41, a scraper 42, and a drive source 43. The drive rod 41 is axially arranged along the conical ring 3 and passes through the innermost conical ring 3. The scraper 42 is disposed at the bottom of the pool body 1 and is connected to the drive rod 41. The output end of the drive source 43 is connected to the drive rod 41.

[0027] Reference Figure 4As shown, the function of the sludge scraping assembly 4 is to continuously and efficiently remove the sludge deposited at the bottom of the sedimentation tank, ensuring the normal operation of the sedimentation tank and the quality of the effluent. Specifically, the scraper 42 is installed close to the bottom of the tank body 1, and the drive source 43 drives the drive shaft to rotate, which in turn drives the scraper 42 to scrape the sludge. As a preferred embodiment of this utility model, the side of the scraper 42 that is in contact with the tank body 1 is tapered, so that the sludge scraped by the scraper 42 can be collected in one direction, facilitating subsequent centralized cleaning of the sludge.

[0028] Furthermore, a collection trough 11 is provided at the bottom of the pool body 1. The sludge scraped off by the scraper 42 enters the collection trough 11. Preferably, a drain valve is provided at the bottom of the collection trough 11 to promptly remove the sludge in the collection trough 11, thereby achieving the purpose of continuous settling.

[0029] Furthermore, a guide pipe 5 is sleeved on the outside of the drive rod 41, the output end of the guide pipe 5 extends into the bottom of the support frame 2, and the input end of the guide pipe 5 is provided with a water inlet 51.

[0030] Specifically, the water to be treated enters the guide pipe 5 through the inlet 51. The output end of the guide pipe 5 extends into the bottom of the support frame 2, introducing the water into the bottom of the inclined plate. When the liquid level inside the pool 1 rises to the inclined plate, it settles through the inclined plate, and the sediment settles to the bottom of the pool 1.

[0031] Furthermore, a water collection trough 6 is provided on the side wall of the pool body 1, the height of the water collection trough 6 is higher than the height of the conical ring 3, and a weir plate 7 is provided on the side wall of the water collection trough 6.

[0032] Specifically, after suspended particles settle to the bottom of the sedimentation tank, a clear water zone forms on the upper layer. The water collection trough 6 is located at the top of the conical ring 3 (inclined plate) to collect the clear water that has completed settling. The water collection trough 6 can ensure the stability of the effluent and prevent flow interruption. Secondly, the weir plate 7 is usually installed at the inlet end of the water collection trough 6, that is, at the junction of the clear water zone and the water collection trough 6. It is a transition barrier connecting the clear water zone and the water collection trough 6. Its core function is to control the uniformity of the effluent, regulate the water flow state, and intercept residual suspended particles.

[0033] In summary, this utility model introduces an annular self-stabilizing inclined plate sedimentation tank. The inclined plates of the sedimentation tank in this utility model are composed of multiple sets of topless conical annular inclined plates with diameters ranging from large to small. The structure of a single inclined plate is stable; no support structure is required between different layers of inclined plates, avoiding blockage caused by sludge accumulation; reducing the number of downtimes and improving production efficiency.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
