Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater sedimentation device with good separation effect. Background Technology

[0002] In the wastewater treatment process, sedimentation is one of the key steps. Its function is to use gravity to settle suspended solids and particulate impurities in the wastewater, thereby achieving the initial separation of wastewater and impurities and providing conditions for subsequent advanced treatment.

[0003] In the field of wastewater treatment, sedimentation equipment is the core device for removing suspended solids. Existing horizontal flow sedimentation tanks rely on gravity settling, have a long hydraulic retention time, and have poor ability to capture fine particles. Although the single inclined plate structure shortens the settling distance, the flow between the plates is unstable, which can easily lead to the back mixing of settled sludge. Therefore, this utility model provides a wastewater sedimentation equipment with good separation effect. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater sedimentation device with good separation effect to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater sedimentation device with good separation effect, including a sedimentation tank, a preliminary treatment chamber at one end of the sedimentation tank, a grid frame inside the preliminary treatment chamber, an inclined separation net inside the sedimentation tank, a honeycomb plate slidably connected to one side of the sedimentation tank, an input pipe on one side of the preliminary treatment chamber, and a discharge section at the bottom of the sedimentation tank.

[0006] In a preferred embodiment, limiting frames are provided on both sides of the inner wall of the preliminary processing chamber, and a grid plate frame is slidably connected inside the limiting frame, the grid plate frame being located on one side of the input pipe.

[0007] In a preferred embodiment, an expansion section is provided on one side of the preliminary treatment chamber. The expansion section is funnel-shaped, and the preliminary treatment chamber is connected to the sedimentation tank through the expansion section.

[0008] In a preferred embodiment, the sedimentation tank is provided with inclined frames on both sides, and each of the two inclined frames is provided with a first limiting groove.

[0009] In a preferred embodiment, the separation net is provided with a sliding frame on the outside, and both sides of the sliding frame are provided with protrusions that are adapted to the first limiting groove. The bottom end of the separation net is in contact with the bottom of the sedimentation tank cavity.

[0010] In a preferred embodiment, the bottom of the sedimentation tank is provided with second limiting grooves on both sides, the honeycomb plate is provided with side plates that are adapted to the second limiting grooves, and the contact surfaces of the side plates and the sedimentation tank are provided with sealing rings.

[0011] In a preferred embodiment, the honeycomb panel is located directly below the separation mesh, and the discharge section is located directly below the honeycomb panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This wastewater sedimentation equipment with good separation effect uses a three-stage modular separation structure and slidable and detachable components. Wastewater passes through a grid frame, an inclined separation net and a honeycomb plate (deep sedimentation) in sequence to form gradient separation and improve the removal rate.

[0014] The separation net is connected to the first limiting groove via a sliding frame, and the honeycomb panel is connected to the second limiting groove via a side plate. Both can be pulled out and disassembled laterally. There is no need to empty the tank during maintenance, which shortens the replacement time of a single component. The funnel-shaped expansion section at the end of the preliminary treatment chamber effectively reduces the intensity of influent turbulence. The design of the bottom end of the separation net reaching the bottom of the tank prevents sludge back mixing. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figures 1-3This utility model provides a wastewater sedimentation device with good separation effect, including a sedimentation tank 1. One end of the sedimentation tank 1 is provided with a preliminary treatment chamber 101. The interior of the preliminary treatment chamber 101 is provided with a grid plate frame 3. Both sides of the inner wall of the preliminary treatment chamber 101 are provided with a limiting frame 201. The grid plate frame 3 is slidably connected inside the limiting frame 201. The grid plate frame 3 is located on one side of the input pipe 2. One side of the preliminary treatment chamber 101 is provided with an expansion part 102. The expansion part 102 is funnel-shaped. The preliminary treatment chamber 101 is connected to the sedimentation tank 1 through the expansion part 102.

[0022] Wastewater enters the preliminary treatment chamber 101 through the inlet pipe 2. The inlet pipe 2 serves as the initial channel for wastewater entering the equipment, guiding the wastewater to be treated to the preliminary treatment area. Upon entering the preliminary treatment chamber 101, the wastewater first encounters the bar screen 3. The bar screen 3 has bar strips at a certain spacing, which can intercept large debris in the wastewater, such as branches, plastic bags, and stones. These large debris are blocked within the preliminary treatment chamber 101 by the bar screen 3, while the wastewater continues to flow through the bar screen 3. The bar screen 3 is slidably connected to the retaining frames 201 on both sides of the inner wall of the preliminary treatment chamber 101. This design allows the bar screen 3 to be easily pulled out and inserted from the retaining frames 201.

[0023] When the debris intercepted on the bar screen 3 accumulates to a certain extent, the staff can easily pull the bar screen 3 out of the limiting frame 201, clean the debris, and then insert it back into its original position, ensuring the normal operation of the equipment and the initial filtration effect. The wastewater that has undergone initial filtration enters the sedimentation tank 1 through the funnel-shaped expansion section 102. The funnel shape of the expansion section 102 plays a buffering and guiding role, which can gradually slow down the flow rate of the wastewater and make the water flow more stable. This can prevent the wastewater from entering the sedimentation tank 1 directly at a high speed and with a large impact force, thereby reducing the disturbance to the water flow in the sedimentation tank 1 and creating good conditions for the subsequent sedimentation process.

[0024] The bar screen 3 initially intercepts large debris in the sewage, preventing it from entering the sedimentation tank 1. If large debris enters the sedimentation tank 1, it will occupy the effective volume of the sedimentation tank 1, reduce the residence time of sewage in the sedimentation tank 1, affect the sedimentation effect, cause equipment failure, and increase maintenance costs. The setup of the preliminary treatment chamber 101 and the bar screen 3 effectively solves these problems and improves the operating efficiency and stability of the entire sewage treatment system.

[0025] The funnel-shaped design of the expansion section 102 allows sewage to enter the sedimentation tank 1 smoothly, reducing turbulence and eddies in the water flow. During the sedimentation process, the stability of the water flow is crucial for the settling of suspended solids. If the water flow is unstable, it will generate a large shear force, causing the already settled suspended solids to resuspend, reducing the sedimentation effect. The presence of the expansion section 102 ensures the stability of the water flow in the sedimentation tank 1, which is conducive to the rapid settling of suspended solids to the bottom of the sedimentation tank 1 under the action of gravity, thereby improving the sedimentation efficiency and enabling the sewage to be purified more effectively.

[0026] In this embodiment, the sedimentation tank 1 is provided with an inclined separation net 501 inside, and inclined brackets 4 are provided on both sides of the sedimentation tank 1. The two inclined brackets 4 are provided with a first limiting groove 401 inside. The separation net 501 is provided with a sliding frame 5 outside. The sliding frame 5 is provided with protrusions on both sides that are adapted to the first limiting groove 401. The bottom end of the separation net 501 is in contact with the bottom of the inner cavity of the sedimentation tank 1. A honeycomb plate 601 is slidably connected to one side of the sedimentation tank 1. An input pipe 2 is provided on one side of the preliminary treatment chamber 101. A discharge part 103 is provided at the bottom of the sedimentation tank 1. The bottom of the other side of the sedimentation tank 1 is provided with a second limiting groove 602 on both sides. The honeycomb plate 601 is provided with a side plate 6 that is adapted to the second limiting groove 602 outside. A sealing ring is provided on the contact surface between the side plate 6 and the sedimentation tank 1. The honeycomb plate 601 is located directly below the separation net 501, and the discharge part 103 is located directly below the honeycomb plate 601.

[0027] The sedimentation tank 1 is equipped with an inclined separation net 501, which is connected to the inclined frames 4 on both sides of the sedimentation tank 1 via an external sliding frame 5. The sliding frame 5 has protrusions on both sides that fit the first limiting groove 401 inside the inclined frame 4. This design ensures that the separation net 501 is securely installed inside the sedimentation tank 1, and the bottom end of the separation net 501 contacts the bottom of the inner cavity of the sedimentation tank 1. When wastewater flows in the sedimentation tank 1, relatively small suspended solids that still require further separation encounter the separation net 501. The separation net 501 has certain pores, which can intercept these suspended solids, causing them to adhere to the surface of the separation net 501 or be blocked on the side of the separation net 501 closer to the wastewater flow. The wastewater can continue to flow backward through the pores of the separation net 501. The suspended solids intercepted on the separation net 501, under their own gravity, will slide down the inclined surface of the separation net 501 and eventually accumulate at the bottom of the sedimentation tank 1 near the bottom end of the separation net 501.

[0028] A honeycomb plate 601 is slidably connected to one side of the sedimentation tank 1. The honeycomb plate 601 is located directly below the separation net 501. After passing through the separation net 501, the sewage continues to flow downward and contacts the honeycomb plate 601. The honeycomb plate 601 is provided with side plates 6 that are adapted to the second limiting grooves 602 on both sides of the bottom of the other side of the sedimentation tank 1. Sealing rings are provided on the contact surfaces of the side plates 6 and the sedimentation tank 1 to ensure the sealing between the honeycomb plate 601 and the sedimentation tank 1 and prevent sewage leakage. The special honeycomb structure of the honeycomb plate 601 increases the contact area between the sewage and the plate surface, making the water flow more evenly dispersed and slowing down the water flow speed. This further provides sedimentation time and space for the small particles in the sewage, which helps the small particles settle. At the same time, the honeycomb plate 601 can play a certain role in rectifying the water flow, so that the water flows smoothly to the bottom of the sedimentation tank 1. The bottom of the sedimentation tank 1 is provided with a discharge part 103, through which the water flows out.

[0029] The separation net 501 can intercept smaller suspended solids that fail to settle during the initial sedimentation, further improving the separation accuracy of the wastewater sedimentation equipment and significantly improving the quality of the effluent, thus providing more favorable conditions for subsequent advanced treatment.

[0030] The separation net 501 is set at an angle, so the suspended solids that are intercepted can automatically slide down the inclined surface to the bottom of the sedimentation tank 1. This avoids the accumulation of impurities on the separation net 501 and blockage of the pores, ensuring the long-term effective use of the separation net 501. It also makes it easier for staff to clean the impurities at the bottom of the sedimentation tank 1, reducing the difficulty and workload of the cleaning work.

[0031] The separation net 501 is installed and fixed by the sliding frame 5 cooperating with the first limiting groove 401 on the inclined frame 4. This structural design makes the installation and disassembly of the separation net 501 very convenient. After the separation net 501 has been used for a period of time, a lot of impurities may be attached to its surface, affecting the separation effect. At this time, the staff can easily pull the separation net 501 out of the inclined frame 4 for cleaning or replacement, and then reinstall it. No complicated operation or professional tools are required, which greatly improves the maintenance efficiency of the equipment.

[0032] The honeycomb structure of the honeycomb panel 601 increases the contact area between sewage and the panel surface, slows down the water flow, provides more opportunities for the sedimentation of tiny particles in the sewage, further improves the sedimentation efficiency, and enables impurities in the sewage to be separated more thoroughly.

[0033] The honeycomb panel 601 acts as a flow straightener, making the water flow more smoothly to the bottom of the sedimentation tank 1, reducing turbulence and eddies, preventing the settled sludge from being resuspended due to water flow disturbance, and ensuring the stability of the sedimentation effect.

[0034] The working principle and usage process of this utility model are as follows: First, the sewage enters the primary treatment chamber 101 through the input pipe 2 on the side of the primary treatment chamber 101. Large-sized debris is intercepted by the grid frame 3. After the sewage passes through the grid frame 3, it flows smoothly into the sedimentation tank 1 through the funnel-shaped expansion part 102.

[0035] The separation net 501, which is inclinedly installed in the sedimentation tank 1, is adapted and fixed to the first limiting groove 401 of the inclined frame 4 on both sides of the sedimentation tank 1 by the protrusions on both sides of the sliding frame 5. The bottom end contacts the bottom of the sedimentation tank 1. When the sewage flows, the separation net 501 intercepts smaller suspended solids, and the impurities slide down the inclined surface to the bottom of the sedimentation tank 1.

[0036] The honeycomb plate 601 located directly below the separation net 501 is adapted to the second limiting groove 602 at the bottom of the other side of the sedimentation tank 1 via the side plate 6. The side plate 6 has a sealing ring on the contact surface with the sedimentation tank 1. After the sewage passes through the separation net 501, it comes into contact with the honeycomb plate 601. Its honeycomb structure increases the contact area, slows down the water flow, helps the small particles to settle and straightens the water flow.

[0037] The bottom discharge section 103 of the sedimentation tank 1 is located directly below the honeycomb plate 601. When the bottom sludge accumulates to a certain extent, the treated wastewater is discharged through the discharge section 103 to achieve sludge-water separation.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
