Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and hydropower construction technology, and in particular, it is a wastewater discharge device used in water conservancy and hydropower construction. Background Technology

[0002] Wastewater treatment is a crucial step in water conservancy and hydropower construction. Wastewater typically contains large amounts of solid impurities and sludge. Direct discharge into the environment not only causes pollution but may also violate relevant environmental regulations. Traditional wastewater treatment methods usually include simple sedimentation and filtration steps, but these methods are often inefficient, unable to effectively separate solid impurities and sludge from the wastewater, leading to excessive burden on subsequent treatment equipment and easily causing secondary pollution.

[0003] Traditional wastewater treatment equipment lacks effective preliminary sedimentation and separation steps, resulting in a large amount of solid impurities and sludge directly entering the treatment system. This increases the burden on subsequent treatment equipment and reduces treatment efficiency. Due to the lack of an effective preliminary sedimentation step, solid impurities and sludge easily accumulate inside the treatment equipment, leading to frequent blockages and increased maintenance frequency and costs. This not only affects the normal operation of the equipment but may also cause treatment interruptions or delays. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater discharge device for water conservancy and hydropower construction, so as 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 discharge device for water conservancy and hydropower construction, comprising a water conservancy and hydropower wastewater treatment tank, wherein an inlet pipe extends through one side of the outer wall of the water conservancy and hydropower wastewater treatment tank, and a pre-treatment pipeline assembly is provided at the end of the inlet pipe away from the water conservancy and hydropower wastewater treatment tank. The pre-treatment pipeline assembly includes a U-shaped sedimentation pipe sealed and connected to the inlet end of the inlet pipe and a sludge collection tank located directly below the U-shaped sedimentation pipe and embedded in the ground. The U-shaped sedimentation pipe includes two... The system comprises symmetrically arranged longitudinal connecting pipes, a sedimentation horizontal pipe integrally connected between the bottom ends of the two longitudinal connecting pipes, and horizontal connecting pipes integrally connected to opposite sides of the top ends of the two longitudinal connecting pipes. The bottom of the sedimentation horizontal pipe is provided with a funnel sedimentation section, and a sewage discharge pipe is connected through the bottom end of the funnel sedimentation section. The sewage discharge pipe is located directly above the sludge collection tank. Spray cleaning components are extended externally from the two longitudinal connecting pipes. The spray cleaning components spray the wastewater accumulated in the longitudinal connecting pipes onto the inner wall of the sludge collection tank, thereby flushing the sludge.

[0006] In this preferred embodiment, the sewage pipe is equipped with a first solenoid valve, and a drain pipe is connected through the lower part of the two longitudinal connecting pipes on opposite sides, with a second solenoid valve in each drain pipe.

[0007] In this preferred embodiment, the spraying and cleaning assembly includes a U-shaped spray pipe fixed between the outer walls of two longitudinal connecting pipes and multiple spray heads that are equidistantly and longitudinally connected to the bottom surface of the U-shaped spray pipe.

[0008] In this preferred embodiment, both drainage pipes are connected to the U-shaped spray pipe, so that when the second solenoid valve is opened, the water accumulated in the longitudinal connecting pipe can flow into the U-shaped spray pipe and be sprayed out through the spray head.

[0009] In a preferred embodiment of this scheme, the inner wall of the sludge collection tank is provided with an inclined slope, and multiple spray heads are located directly above the inclined slope, so that the water sprayed by the spray heads can wash away solid impurities and silt attached to the inclined slope.

[0010] In this preferred embodiment, one of the transverse connecting pipes is connected to the water conservancy and hydropower wastewater treatment tank through the first support structure component, and the other transverse connecting pipe is fixedly erected on the ground on one side of the sludge collection tank through the second support structure component.

[0011] In a preferred embodiment of this scheme, the first support structure component includes a first fixing collar fixedly sleeved on one of the transverse connecting pipes and two inclined support rods symmetrically welded to the outer wall of the periphery of the first fixing collar. The free ends of the two inclined support rods are fixedly connected to the water conservancy and hydropower wastewater treatment tank by bolts.

[0012] In a preferred embodiment of this scheme, the second support structure component includes a second fixing collar fixedly sleeved on another transverse connecting pipe and a support pole welded to the bottom of the second fixing collar, wherein the support pole is fixedly erected on the ground.

[0013] In this preferred embodiment, the U-shaped spray pipe is located behind the sewage pipe, and a door is provided on one side of each of the water conservancy and hydropower wastewater treatment tanks.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This wastewater discharge device for water conservancy and hydropower construction utilizes a pre-treatment pipeline design that allows wastewater to undergo preliminary sedimentation before entering the wastewater treatment tank, significantly reducing the amount of solid impurities and sludge entering the tank. This not only reduces the workload of subsequent treatment steps but also improves overall treatment efficiency. The reduced amount of solid impurities and sludge entering the treatment tank means that subsequent treatment equipment does not need to consume excessive energy to process these impurities, thereby lowering the overall system energy consumption.

[0016] Before the wastewater enters the wastewater treatment tank of the hydropower plant, the design of the U-shaped sedimentation pipe allows most of the solid impurities and sludge in the wastewater to settle and be discharged centrally into the sludge collection tank. This process ensures that the wastewater entering the treatment tank has undergone preliminary purification, reducing the burden on subsequent treatment equipment. The design of the discharge pipe allows the settled solid impurities and sludge to be discharged centrally into the sludge collection tank, facilitating unified treatment and cleaning, and reducing the risk of environmental pollution.

[0017] When wastewater delivery is stopped, the residual wastewater enters the spray cleaning component through the drain pipe and the second solenoid valve. The wastewater is then sprayed onto the inner wall of the sludge collection tank through the spray head, washing away the attached solid impurities and sludge, keeping the system clean and reducing the need for manual maintenance.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] This embodiment provides, for example Figures 1 to 3The wastewater discharge device shown includes a wastewater treatment tank 1 for water conservancy and hydropower construction. An inlet pipe 5 extends through one outer wall of the wastewater treatment tank 1. A pre-treatment pipeline assembly 6 is installed at the end of the inlet pipe 5 furthest from the wastewater treatment tank 1. The pre-treatment pipeline assembly 6 includes a U-shaped sedimentation pipe 7 sealed to the inlet end of the inlet pipe 5 and a sludge collection tank 3 located directly below the U-shaped sedimentation pipe 7 and embedded in the ground. The U-shaped sedimentation pipe 7 includes two symmetrically arranged longitudinal connecting pipes 13 and an integral connecting pipe... A sedimentation horizontal pipe 14 is connected between the bottom ends of two longitudinal connecting pipes 13, and a transverse connecting pipe 12 is integrally connected to the opposite sides of the top ends of the two longitudinal connecting pipes 13. A funnel sedimentation section 17 is provided at the bottom of the sedimentation horizontal pipe 14. A sewage discharge pipe 18 is connected through the bottom end of the funnel sedimentation section 17. The sewage discharge pipe 18 is located directly above the sludge collection tank 3. A spray cleaning component is extended to the outside of the two longitudinal connecting pipes 13. The spray cleaning component sprays the wastewater accumulated in the longitudinal connecting pipes 13 onto the inner wall of the sludge collection tank 3, thereby flushing the sludge. A horizontal connecting pipe 12, located away from the water conservancy and hydropower wastewater treatment tank 1, connects to an external water conservancy and hydropower construction wastewater source. A water pump transports the wastewater to a U-shaped sedimentation pipe 7. The wastewater then flows through the horizontal connecting pipe 12 away from the water conservancy and hydropower wastewater treatment tank 1 into a vertical connecting pipe 13 and a sedimentation pipe 14. From the side closer to the water conservancy and hydropower wastewater treatment tank 1, the wastewater flows into the inlet pipe 5, thus entering the water conservancy and hydropower wastewater treatment tank 1 for filtration. The design of the sedimentation pipe 14 and the funnel sedimentation section 17 allows solid impurities and sludge in the flowing water conservancy and hydropower wastewater to settle into these components, while the water continues to flow from the vertical connecting pipe 13 and the horizontal connecting pipe 12 into the inlet pipe 5. This design reduces the amount of solid impurities and sludge entering the wastewater treatment tank 1, thereby alleviating the filtration burden on the tank. Solid impurities and sludge accumulated in the sedimentation pipe 14 and funnel sedimentation section 17 can be discharged downwards into the sludge collection tank 3, achieving centralized treatment of solid impurities and sludge. When wastewater is no longer supplied to the U-shaped sedimentation pipe 7, some wastewater accumulates in the two longitudinal connecting pipes 13 and does not flow into the inlet pipe 5. Through the design of the spray cleaning component, the wastewater accumulated in these two longitudinal connecting pipes 13 flows into the spray cleaning component, which sprays the wastewater into the sludge collection tank 3 to flush it. This not only discharges the accumulated wastewater but also cleans the sludge collection tank 3. Wastewater enters the transverse connecting pipe 12 from the outside via a water pump, and then flows into the longitudinal connecting pipe 13 and the sedimentation pipe 14.Due to gravity, solid impurities and silt will settle into the sedimentation pipe 14 and the funnel sedimentation section 17, while the clean water will continue to flow back to the inlet pipe 5 and enter the water conservancy and hydropower wastewater treatment tank 1 for further treatment. This effectively separates solid impurities and silt from the wastewater, reduces the burden on subsequent treatment equipment, and improves the overall treatment efficiency. Through reasonable structural design, it is ensured that the wastewater has been initially purified before entering the treatment tank, reducing the workload and energy consumption of subsequent treatment steps.

[0027] In this embodiment, a first solenoid valve 19 is installed inside the sewage pipe 18, and a drain pipe 20 is connected through the lower part of each of the two longitudinal connecting pipes 13 on opposite sides. Each drain pipe 20 has a second solenoid valve 21. The first solenoid valve 19 is used to control the opening and closing of the sewage pipe 18 to ensure that the sediment is discharged to the sludge collection tank 3 when needed. The second solenoid valve 21 is used to control the opening and closing of the drain pipe 20 to introduce residual wastewater into the spray cleaning component. By precisely controlling the discharge process through the solenoid valves, unnecessary discharge or blockage problems are avoided, improving the reliability and controllability of the system. This ensures that the residual wastewater can be effectively recycled after the wastewater transport is stopped, reducing resource waste.

[0028] In this embodiment, the spray cleaning assembly includes a U-shaped spray pipe 22 fixed between the outer walls of two longitudinal connecting pipes 13 and multiple spray heads 23 equidistantly longitudinally connected to the bottom surface of the U-shaped spray pipe 22. When the second solenoid valve 21 is opened, residual wastewater flows into the U-shaped spray pipe 22 through the drain pipe 20 and is sprayed onto the inner wall of the sludge collection tank 3, especially the inclined landslide 4 area, through the spray heads 23 to flush and remove attached solid impurities and sludge. Through the design of the spray cleaning assembly, effective cleaning of the inner wall of the sludge collection tank 3 is achieved, preventing the long-term accumulation of solid impurities and sludge, which affects operating efficiency, improving self-cleaning ability, reducing the need for manual maintenance, and lowering operating costs.

[0029] In this embodiment, both drain pipes 20 are connected to the U-shaped spray pipe 22, allowing water accumulated in the longitudinal connecting pipe 13 to flow into the U-shaped spray pipe 22 and be sprayed out through the spray head 23 when the second solenoid valve 21 is opened. The connection between the drain pipe 20 and the U-shaped spray pipe 22 ensures that residual wastewater flows smoothly into the spray assembly and is evenly sprayed onto the inner wall of the sludge collection tank 3 through the spray head 23, achieving the cleaning purpose. This ensures that residual wastewater can be effectively utilized, reducing wastewater waste, enhancing the cleaning function, increasing automation, reducing manual intervention, and improving stability and reliability.

[0030] In this embodiment, the inner wall of the sludge collection tank 3 is provided with an inclined slope 4, and multiple spray heads 23 are located directly above the inclined slope 4, so that the water sprayed by the spray heads 23 can wash away solid impurities and silt attached to the inclined slope 4. The design of the inclined slope 4 facilitates the sliding of solid impurities and silt down the slope to the bottom for centralized treatment. The water flow from the spray heads 23 can effectively wash the slope surface and keep it clean. The design of the inclined slope 4 facilitates the centralized treatment of solid impurities and silt, reduces the difficulty of cleaning, and the water flow from the spray heads 23 can effectively clean the slope surface, prevent the accumulation of solid impurities and silt, and extend the service life of the equipment.

[0031] In this embodiment, one horizontal connecting pipe 12 is connected to the water conservancy and hydropower wastewater treatment tank 1 via the first support structure component 8, and the other horizontal connecting pipe 12 is fixedly erected on the ground on one side of the sludge collection tank 3 via the second support structure component 9. The first support structure component 8 fixes the horizontal connecting pipe 12 with the first fixing collar 10 and the inclined support rod 11, making it stably connected to the water conservancy and hydropower wastewater treatment tank 1; the second support structure component 9 fixes the other horizontal connecting pipe 12 with the second fixing collar 15 and the support rod 16, ensuring that it is stably erected on the ground, providing a stable support structure, ensuring the stability of the entire device, and preventing damage caused by vibration or external force. The design of the support structure component makes the device installation more flexible, adaptable to different site environments, and improves the versatility and practicality of the device.

[0032] In this embodiment, the first support structure component 8 includes a first fixing collar 10 fixedly sleeved on one of the transverse connecting pipes 12 and two inclined support rods 11 symmetrically welded to the outer periphery of the first fixing collar 10. The free ends of the two inclined support rods 11 are fixedly connected to the water conservancy and hydropower wastewater treatment tank 1 by bolts. The first fixing collar 10 fixes the transverse connecting pipe 12, and the inclined support rods 11 provide additional support force. They are firmly connected to the water conservancy and hydropower wastewater treatment tank 1 by bolts, forming a stable support structure, which enhances the stability of the transverse connecting pipe 12 and prevents it from shifting or deforming during use. The bolted connection facilitates disassembly and maintenance, improving the maintainability and flexibility of the device.

[0033] In this embodiment, the second support structure component 9 includes a second fixing collar 15 fixedly sleeved on another transverse connecting pipe 12 and a support pole 16 welded to the bottom of the second fixing collar 15. The support pole 16 is fixedly erected on the ground. The second fixing collar 15 fixes the transverse connecting pipe 12, and the support pole 16 securely erects it on the ground, ensuring the stability and safety of the transverse connecting pipe 12, providing additional support points, enhancing the stability of the overall device, and preventing damage caused by external forces. The design of the support pole 16 allows the device to adapt to different terrains, improving the applicability and reliability of the device.

[0034] In this embodiment, the U-shaped spray pipe 22 is located behind the sewage pipe 18, and a door 2 is provided on one side of the water conservancy and hydropower wastewater treatment tank 1. The position design of the U-shaped spray pipe 22 ensures that it can cover the key areas of the sludge collection tank 3 for effective spray cleaning. The door 2 provides a convenient entrance for inspecting and maintaining the interior of the water conservancy and hydropower wastewater treatment tank 1, ensuring the effective operation of the spray cleaning components, improving the cleaning effect of the sludge collection tank 3, and the design of the door 2 facilitates daily maintenance and troubleshooting, improving maintainability and ease of operation.

[0035] Working principle

[0036] This wastewater discharge device for water conservancy and hydropower construction pumps wastewater from an external water conservancy and hydropower construction wastewater source to a horizontal connecting pipe 12. The wastewater then flows into a U-shaped sedimentation pipe 7 through a horizontal connecting pipe 12 located away from the water conservancy and hydropower wastewater treatment tank 1. The horizontal connecting pipe 12 is connected to a longitudinal connecting pipe 13. The wastewater further flows into two longitudinal connecting pipes 13 and a sedimentation horizontal pipe 14. As the wastewater flows through the longitudinal connecting pipe 13 and the sedimentation horizontal pipe 14, due to gravity, solid impurities and sludge in the wastewater will settle into the sedimentation horizontal pipe 14 and the funnel sedimentation section 17. The clear water after sedimentation continues to flow back to the inlet pipe 5 through the longitudinal connecting pipe 13 and the horizontal connecting pipe 12 on the side close to the water conservancy and hydropower wastewater treatment tank 1, and finally enters the water conservancy and hydropower wastewater treatment tank 1 for further filtration treatment.

[0037] Solid impurities and sludge that settle in the sedimentation pipe 14 and the funnel sedimentation section 17 are discharged into the sludge collection tank 3 through the sewage pipe 18. The sewage pipe 18 is equipped with a first solenoid valve 19 to control the discharge process. When discharge is required, the first solenoid valve 19 is opened to allow the sediment to flow smoothly into the sludge collection tank 3 for centralized treatment. After the wastewater is stopped from being transported to the U-shaped sedimentation pipe 7, some wastewater may still remain in the longitudinal connecting pipe 13. At this time, by opening the second solenoid valve 21 on the drain pipe 20, this residual wastewater will be introduced into the U-shaped spray pipe 22. The bottom surface of the U-shaped spray pipe 22 is equidistantly equipped with multiple spray heads 23 to spray the wastewater back onto the inner wall of the sludge collection tank 3, especially the inclined slope 4 area, to flush and remove the solid impurities and sludge attached to the inner wall.

[0038] The first support structure component 8 fixes a horizontal connecting pipe 12 through the first fixing collar 10 and the inclined support rod 11, and connects the horizontal connecting pipe to the water conservancy and hydropower wastewater treatment tank 1. The second support structure component 9 fixes another horizontal connecting pipe 12 through the second fixing collar 15 and the support rod 16, so that it is stably erected on the ground on one side of the sludge collection tank 3, ensuring the stability of the entire device.

[0039] By opening the door 2, the interior of the water conservancy and hydropower wastewater treatment tank 1 can be inspected and maintained to ensure that the equipment is operating normally.
