Description

Technical Field

[0001] This utility model relates to the field of wastewater sedimentation technology, and more specifically, to a sedimentation device for wastewater treatment. Background Technology

[0002] Settling devices for wastewater treatment are core equipment that utilizes gravity to achieve solid-liquid separation. They are widely used in the pretreatment, intermediate treatment, or advanced treatment stages of wastewater treatment processes. Their core principle is to slow down the wastewater flow rate and expand the settling space, allowing suspended particles and flocs (formed after coagulation and flocculation treatment) in the wastewater to naturally settle to the bottom of the device under gravity. The clarified supernatant is then discharged from the top or middle of the device, thereby reducing the turbidity of the wastewater and removing some pollutants (such as suspended solids, organic matter, phosphorus, etc.).

[0003] However, existing sedimentation devices for wastewater treatment have the following problems during operation:

[0004] 1. The internal structure is difficult to maintain, increasing the maintenance difficulty for relevant personnel;

[0005] 2. Drain pipes are mostly fixed and cannot be adjusted according to actual needs.

[0006] In summary, existing sedimentation devices for wastewater treatment suffer from the problems of inconvenient maintenance of the internal structure and the non-fixed drain pipe. Therefore, a sedimentation device for wastewater treatment is disclosed. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0021] This invention provides a sedimentation device for wastewater treatment. Water inlets are located on both sides of the top of the water storage base, allowing for a stable inflow of wastewater. Filter holes on the inner wall provide preliminary filtration of the incoming wastewater, effectively intercepting large particles and preventing them from directly entering the sedimentation area and affecting the treatment effect. A drain seat at the bottom of the water storage base connects to a drain pipe. Together with an internal spiral drain column and drive motor, it efficiently transports settled sludge and other sediments to the drain pipe for discharge, ensuring the cleanliness of the device's interior. Two drain pipes are located at both ends inside the water storage base. The pump body at the top provides power for drainage, facilitating the timely discharge of the treated supernatant. Meanwhile, the overlapping blocks on both sides of the drain pipe are located at the four corners inside the water storage base, providing stable support for the drain pipe and ensuring a smooth drainage process. In addition, the overlapping blocks can move the drain pipe, and by adjusting the position of the overlapping blocks inside the water storage base, the height of the drain pipe can be flexibly adjusted to meet the drainage needs of different water levels. It is worth noting that the pump body uses a low-head pump, which generates low suction. The weak suction will not disrupt the stratification interface between the supernatant and the turbid liquid.

Detailed Implementation

[0028] The present invention will be further described below with reference to specific embodiments.

To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0029] Example 1

[0030] like Figure 1-5 As shown, this utility model provides a sedimentation device for wastewater treatment, including a water storage base 10, with water inlets 101 on both sides of the top of the water storage base 10, a sewage discharge base 20 at the bottom of the water storage base 10, a sewage discharge channel 30 at the bottom of the sewage discharge base 20, and a filter hole 1011 on the inner wall of the water storage base 10 on one side of the water inlet 101; a spiral sewage discharge column 40 is provided inside the sewage discharge channel 30, a drive motor for driving the spiral sewage discharge column 40 is provided at one end of the sewage discharge channel 30, and a sewage discharge pipe 100 is provided at the other end of the sewage discharge channel 30; two drain pipes 50 are provided at both ends inside the water storage base 10, and overlapping blocks 70 are provided on both sides of the drain pipes 50, with the overlapping blocks 70 located at the four corners inside the water storage base 10; and a pump body 60 is provided at the top of the drain pipes 50.

[0031] This utility model discloses a sedimentation device for wastewater treatment. The water storage base 10 has inlets 101 on both sides of its top, allowing for a stable inflow of wastewater. Filter holes 1011 on the inner wall provide preliminary filtration of the incoming wastewater, effectively intercepting large particles and preventing them from directly entering the sedimentation area and affecting the treatment effect. A drain seat 20 at the bottom of the water storage base 10 is connected to a drain channel 30. Together with the internal spiral drain column 40 and drive motor, it efficiently transports settled sludge and other sediments to the drain pipe 100 for discharge, ensuring the cleanliness of the device's interior. Two drain pipes 50 are located at both ends inside the water storage base 10. The pump body 60 at the top provides power for drainage, facilitating the timely discharge of the treated supernatant. Meanwhile, the overlapping blocks 70 on both sides of the drain pipe 50 are located at the four corners inside the water storage base, providing stable support for the drain pipe and ensuring a smooth drainage process. In addition, the overlapping blocks 70 can move the drain pipe 50. By adjusting the position of the overlapping blocks 70 within the water storage base 10, the height of the drain pipe 50 can be flexibly adjusted to meet the drainage needs of different water levels. It is worth noting that the pump body 60 uses a low-head pump, which generates low suction. The weak suction will not disrupt the stratification interface between the supernatant and the turbid liquid.

[0032] Furthermore, in another embodiment, the water storage seat 10 has a first plate 102 on both sides of the bottom, and the sewage discharge seat 20 has a second plate 202 on both sides of the top, and the first plate 102 and the second plate 202 are detachably fixed together by bolts.

[0033] The water storage seat 10 and the sewage discharge seat 20 are fixed together by the first plate 102 and the second plate 202. When the sewage discharge seat 20 needs to be cleaned or maintained, the water storage seat 10 and the sewage discharge seat 20 can be separated simply by unscrewing the connecting bolts. After the water storage seat 10 and the sewage discharge seat 20 are separated, it is convenient for relevant personnel to maintain the inside of the sewage discharge seat 20, effectively reducing the difficulty and cost of maintenance.

[0034] Furthermore, in another embodiment, the first plate 102 is provided with positioning posts 1021 at both ends of the bottom, and the second plate 202 is provided with positioning grooves 2023 at both ends to accommodate the positioning posts 1021.

[0035] The positioning column 1021 and the positioning groove 2023 can play a pre-positioning role when the water storage seat 10 and the sewage discharge seat 20 are installed, so that the bolt holes on the first plate 102 and the second plate 202 can be quickly aligned, which effectively improves the installation efficiency of both. At the same time, after the positioning column 1021 is embedded in the positioning groove 2023, it can also enhance the overall stability of the water storage seat 10 and the sewage discharge seat 20 after connection, and avoid relative displacement between the two due to vibration and other factors during use, further ensuring the structural reliability of the settling device.

[0036] Furthermore, in another embodiment, the top of the sewage seat 20 is provided with a splicing block 2021, and the bottom of the water storage seat 10 is provided with a splicing groove 103 to accommodate the splicing block 2021.

[0037] The design of the splicing block 2021 and the splicing groove 103 can form a double positioning structure when the water storage seat 10 and the sewage discharge seat 20 are connected. Working together with the positioning column 1021 and the positioning groove 2023, it further improves the accuracy of installation. The outer contour of the splicing block 2021 matches the inner contour of the splicing groove 103. During installation, the splicing block 2021 can be smoothly embedded along the inner wall of the splicing groove 103. This not only helps guide the water storage seat 10 and the sewage discharge seat 20 to quickly find the correct installation position, but also increases the contact area after the two are connected, thereby enhancing the sealing performance of the connection and effectively preventing wastewater leakage at the connection. This provides a more reliable guarantee for the stable operation of the sedimentation device.

[0038] Furthermore, in another embodiment, a sealing gasket 2022 is provided on the periphery of the splicing block 2021 on the drain seat 20.

[0039] The sealing gasket 2022 is made of corrosion-resistant rubber material and can fit tightly against the outer periphery of the splicing block 2021 and the inner wall of the splicing groove 103. When the water storage seat 10 and the sewage seat 20 are spliced ​​together through the splicing block 2021 and the splicing groove 103, the sealing gasket 2022 will be squeezed by the two and undergo elastic deformation, thereby filling the possible tiny gaps between the splicing block 2021 and the splicing groove 103, improving the sealing effect of the connection and preventing wastewater leakage.

[0040] Furthermore, in another embodiment, the drain pipe 50 is provided with a connecting pipe 501 at the top, the connecting pipe 501 is provided with a telescopic hose 502 at the top, and one end of the telescopic hose 502 is connected to the pump body 60.

[0041] During the movement of the drain pipe 50, the flexible hose 502 can adapt to the expansion and contraction, avoiding pulling or bending at the pipe connection due to changes in the position of the drain pipe 50, and ensuring that the drainage path remains unobstructed at all times.

[0042] Furthermore, in another embodiment, the end of the overlapping block 70 away from the drain pipe 50 is provided with a connecting plate 702. There are two sets of connecting plates 702, and each set of connecting plates 702 has two pieces. Each set of connecting plates 702 is connected to a single drain pipe 50, and the four connecting plates 702 are located at the four corners of the outer wall of the water storage base 10. A horizontal plate 703 is provided at the bottom of the connecting plate 702, and the horizontal plate 703 is located between the single sets of connecting plates 702. Fixing plates 80 are provided at both ends of the outer wall of the water storage base 10. The horizontal plate 703 is provided with a meshing groove 7031 for meshing with the fixing plate 80. The fixing plate 80 is provided with a plurality of fixing holes 801, and the meshing groove 7031 is provided with a fixing bolt 7032.

[0043] When the drain pipe 50 needs to be adjusted, the fixing bolt 7032 can be loosened first to release the engagement between the horizontal plate 703 and the fixing plate 80. Then, the overlapping block 70 is pulled to move the drain pipe 50 along the fixing plate 80. After the drain pipe 50 moves to the target position, the fixing bolt 7032 is re-passed through the engagement groove 7031 and screwed into the corresponding fixing hole 801 on the fixing plate 80. Through the threaded engagement between the fixing bolt 7032 and the fixing hole 801, the horizontal plate 703 and the fixing plate 80 are firmly connected, thereby achieving stable fixation of the drain pipe 50 and preventing the drain pipe 50 from shifting due to water flow impact and other factors during the drainage process, thus ensuring the stability and accuracy of the drainage operation.

[0044] Furthermore, in another embodiment, the top of the drain pipe 50 is provided with a limiting plate 701 on the overlapping block 70, the limiting plate 701 has a limiting hole 7011 inside, the limiting hole 7011 is provided with a limiting post 90 through it, and the bottom end of the limiting post 90 is fixed to the drain seat 20.

[0045] The setting of the limiting post 90 can guide the movement direction of the drain pipe 50. When the overlapping block 70 drives the drain pipe 50 to move along the fixed plate 80, the limiting hole 7011 will slide along the outer wall of the limiting post 90, effectively preventing the drain pipe 50 from shifting laterally or rotating during the movement, ensuring that the drain pipe 50 always moves smoothly along the preset trajectory. At the same time, the limiting post 90 and the limiting hole 7011 adopt a clearance fit, which reduces the frictional resistance between the two while ensuring the guiding effect, making the position adjustment operation of the drain pipe 50 smoother and less labor-intensive.

[0046] Furthermore, in another embodiment, inclined plates 201 are provided on both sides of the top of the drain duct 30 inside the drain seat 20.

[0047] When wastewater flows from the water storage seat 10 into the sewage discharge seat 20, the inclined plate 201 can buffer and guide the water flow, allowing the water to flow smoothly downward along the surface of the inclined plate 201, avoiding the local turbulence caused by the water flow directly impacting the inner wall of the sewage discharge channel 30. At the same time, the inclined angle design of the inclined plate 201 can also promote the initial sedimentation of suspended particles in the wastewater. Heavier particles slide down the inclined plate 201 to the bottom of the sewage discharge seat 20 under the action of gravity.

[0048] Working principle: Wastewater flows steadily in through the inlets 101 on both sides of the top of the water storage base 10. The filter holes 1011 on the inner wall first filter the wastewater to intercept large particles of impurities. Then the wastewater enters the settling area inside the water storage base 10. Under the action of gravity, the suspended particles gradually settle to the bottom drain seat 20. The inclined plate 201 in the drain seat 20 buffers and guides the water flow, promotes the initial settling of particles, and avoids the water flow directly impacting the drain channel 30. The settled sludge and other sediments are discharged through the drain channel 30 at the bottom of the drain seat 20. The spiral drain column 40 in the drain channel 30, driven by the drive motor, efficiently transports the sediments to the drain pipe 100.

[0049] The treated supernatant is discharged through the drain pipes 50 at both ends inside the water storage base 10. The drain pipes 50 can be moved along the fixed plate 80 via the overlapping blocks 70 to adjust their height and adapt to different water level requirements. During movement, the telescopic hose 502 adapts to ensure unobstructed flow, while the limiting post 90 ensures that the drain pipe 50 moves smoothly along a preset trajectory. When maintenance of the sewage discharge base 20 is required, the bolts connecting the first plate 102 and the second plate 202 can be unscrewed to separate the water storage base 10 and the sewage discharge base 20 for cleaning. The cooperation between the positioning post 1021 and the positioning groove 2023 facilitates subsequent reinstallation and positioning.
