Abstract
Description
Technical Field
[0001] This utility model relates to the field of intercepting well technology, specifically to an intercepting well with sediment separation function. Background Technology
[0002] Interception wells are a key structure in urban drainage systems, mainly used for the management of sewage and rainwater in combined sewer systems. Their core function is to reduce the direct discharge of pollutants into natural water bodies by intercepting, diverting, and regulating water flow, while optimizing the operating load of sewage treatment plants.
[0003] A search revealed an existing patent (publication number: CN221298136U) that discloses a slag interception well, comprising a well body. Three side walls of the well body are respectively connected to an inlet pipe, an outlet pipe, and a sewage pipe. The inlet and outlet pipes are located on opposite sides of the well body and are on the same horizontal plane. The sewage pipe is located at the bottom of the well body. A slag interception assembly is provided at the inlet of the inlet pipe, and a sedimentation tank is provided at the bottom of the well body. In this invention, water flows through the mesh of the filter box into the well body, where impurities are filtered out and accumulated. Some of the silt in the water settles and enters the sedimentation tank, achieving effective filtration and preventing well blockage. Cleaning impurities only requires lifting the filter box and sedimentation tank out of the well body and rinsing them, making cleaning and maintenance convenient and efficient.
[0004] However, the above scheme makes it inconvenient to dredge the settled silt. The settled silt simply enters the sedimentation tank, and the subsequent cleaning still requires staff to clean it, which makes it inconvenient to use. In addition, when the water flow is large, the silt deposited in the sedimentation tank will be stirred up by the water flow, making it inconvenient to settle and separate.
[0005] In view of this, this utility model proposes a diversion well with sedimentation and separation function. Utility Model Content
[0006] This invention proposes a intercepting well with sediment separation function, which solves the problem of inconvenience in dredging settled silt in related technologies.
[0007] The technical solution of this utility model is as follows: A intercepting well with sedimentation and separation function includes an intercepting well body; a guide platform fixedly connected to the lower end of the inner wall of the intercepting well body, a partition fixedly connected to the inner wall of the intercepting well body on one side of the guide platform, and a fine filter plate provided at the top of the partition; a sludge discharge assembly assembled at the lower end of one side inside the intercepting well body, the sludge discharge assembly being used to realize the automatic conveying and discharge of sediment; a filter frame slidably connected to one side inside the intercepting well body, an inlet pipe fixedly connected to the upper end of one side of the intercepting well body, a drain pipe fixedly connected to the lower end of the other side of the intercepting well body, and an overflow pipe fixedly connected to one side of the front of the intercepting well body; and a buffer assembly assembled on the top wall of the filter frame, the buffer assembly being used to prevent excessive water flow from causing excessive impact force on the filter frame.
[0008] The sludge removal assembly includes: a settling trough formed on one side of the bottom wall of the intercepting well body, a sludge removal trough formed at the middle position of the bottom wall of the settling trough, and a sludge removal hopper extending into the settling trough fixedly connected to the bottom end of the guide platform; a servo motor fixedly connected to the lower end of one side of the intercepting well body, the output end of the servo motor extending into the interior of the sludge removal trough and fixedly connected to a spiral sludge removal rod via a coupling; and a sludge removal pipe fixedly connected to one side of the bottom end of the intercepting well body, the top end of the sludge removal pipe communicating with one side of the bottom end of the sludge removal trough.
[0009] Preferably, the inner walls of the guide platform and the sludge discharge hopper are funnel-shaped, and the area of the cross-section at the top of the sludge discharge hopper is larger than the area of the cross-section at the bottom opening of the guide platform.
[0010] Preferably, the two ends of the inner wall of the settling tank are inclined.
[0011] Preferably, the top of the fine filter plate is tilted at a 30-degree angle to the horizontal direction, and a lifting ring is welded to the top of the fine filter plate.
[0012] Preferably, the top two ends of the partition plate are provided with slots, and a locking block that engages with the inside of the slot is fixedly connected to one side of the bottom end of the fine filter plate.
[0013] Preferably, the buffer assembly includes: a fixing groove symmetrically formed on the top wall of the filter frame, a slide rod fixedly connected to the inner wall of the fixing groove, and a slider movably connected to the surface of the slide rod; a fixing spring wound around the surface of the slide rod, with both ends of the fixing spring fixedly connected to one side of the slider and the inner wall of the fixing groove, respectively; and a buffer plate fixedly connected to the bottom ends of the two sliders.
[0014] Preferably, the surfaces of the slider and the slide rod form a sliding structure, and the bottom end of the slider is fixedly connected to the top end of the buffer plate by bolts.
[0015] Preferably, the buffer plate is tilted at a 40-degree angle to the vertical direction, and the buffer plate is provided with through slots at equal intervals.
[0016] The beneficial effects of this utility model are as follows:
[0017] In this invention, sediment in water settles under gravity and is guided by a guide platform to flow into the settling tank via a sludge discharge hopper for storage. The funnel-shaped sludge discharge hopper reduces sediment from being thrown outside the settling tank. The valve on the sludge discharge pipe can be opened, and the servo motor can be started to drive the spiral sludge discharge rod to rotate, transporting the sediment inside the sludge tank and discharging it through the sludge discharge pipe. The inclined inner wall of the settling tank guides the sediment, allowing it to flow smoothly into the sludge tank for subsequent spiral discharge by the spiral sludge discharge rod. This enables automatic sediment discharge. Furthermore, the fine filter plate further prevents the thrown sediment from being discharged through the drain pipe, improving its practicality.
[0018] In this invention, when heavy rain causes excessive water flow into the filter frame, the water first contacts the buffer plate, causing the buffer plate to slide and drive the slider to slide on the surface of the slide rod, compressing the fixed spring. At the same time, the sliding friction between the slider and the slide rod and the resistance of the buffer plate moving in the water can consume the elastic potential energy of the fixed spring compression, thereby reducing the impact force of the water flow and preventing excessive impact force from causing collision damage to the filter frame or damaging the connection between the filter frame and the internal slide rail of the intercepting well body, which would lead to inconvenience in the subsequent up and down sliding of the filter frame and extend its service life.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1
[0028] A preferred embodiment of the intercepting well with sedimentation and separation function provided by this utility model is as follows: Figures 1 to 5 As shown: A intercepting well with sedimentation and separation function includes an intercepting well body 1; a guide platform 5 fixedly connected to the lower end of the inner wall of the intercepting well body 1, a baffle 8 fixedly connected to the inner wall of the intercepting well body 1 on one side of the guide platform 5, and a fine filter plate 9 provided at the top of the baffle 8; a sludge discharge assembly 6 assembled at the lower end of one side inside the intercepting well body 1, the sludge discharge assembly 6 being used to realize the automatic conveying and discharge of sediment; a filter frame 2 slidably connected to one side inside the intercepting well body 1, an inlet pipe 4 fixedly connected to the upper end of one side of the intercepting well body 1, a drain pipe 7 fixedly connected to the lower end of the other side of the intercepting well body 1, and an overflow pipe 10 fixedly connected to one side of the front of the intercepting well body 1; and a buffer assembly 3 assembled on the top wall of the filter frame 2, the buffer assembly 3 being used to prevent excessive water flow from causing excessive impact on the filter frame 2.
[0029] The sludge removal assembly 6 includes: a settling trough 605 formed on one side of the bottom wall of the intercepting well body 1, a sludge removal trough 606 formed at the middle position of the bottom wall of the settling trough 605, and a sludge removal hopper 604 extending into the settling trough 605 fixedly connected to the bottom end of the guide platform 5; a servo motor 601 fixedly connected to the lower end of one side of the intercepting well body 1, the output end of the servo motor 601 extending into the interior of the sludge removal trough 606 and fixedly connected to a spiral sludge removal rod 603 via a coupling; and a sludge removal pipe 602 fixedly connected to one side of the bottom end of the intercepting well body 1, the top end of the sludge removal pipe 602 communicating with one side of the bottom end of the sludge removal trough 606.
[0030] In this embodiment, the silt in the water settles due to gravity and is guided by the guide platform 5 to flow from the sludge discharge hopper 604 into the settling tank 605 for storage. At the same time, the valve on the sludge discharge pipe 602 can be opened, and the servo motor 601 can be started to drive the spiral sludge discharge rod 603 to rotate, so that the silt inside the sludge discharge tank 606 is transported and discharged through the sludge discharge pipe 602. The inner wall of the settling tank 605 is inclined, which can guide the silt and allow it to be smoothly transported into the sludge discharge tank 606, which facilitates the subsequent spiral discharge of the sludge by the spiral sludge discharge rod 603.
[0031] In a further preferred embodiment of the present invention, the inner walls of the guide platform 5 and the mud discharge hopper 604 are funnel-shaped, and the area of the cross-section at the top of the mud discharge hopper 604 is greater than the area of the cross-section at the bottom opening of the guide platform 5.
[0032] In this embodiment, the use of a funnel-shaped sludge discharge hopper 604 can reduce the amount of sludge and sand being blown out of the settling tank 605.
[0033] In a further preferred embodiment of this utility model, the two ends of the inner wall of the settling tank 605 are inclined surfaces.
[0034] In this embodiment, the inclined settling trough 605 is used to allow the silt to be discharged more smoothly into the sludge discharge trough 606.

[0036] In this embodiment, the use of fine filter plate 9 can further prevent the stirred-up mud and sand from being discharged through drain pipe 7.
[0037] In a further preferred embodiment of the present invention, slots 11 are provided at both ends of the top of the partition plate 8, and a block 12 that engages with the inside of the slot 11 is fixedly connected to one side of the bottom of the fine filter plate 9.
[0038] In this embodiment, the initial engagement and installation of the fine filter plate 9 is achieved by using the engagement between the card block 12 and the card slot 11.
[0039] Example 2
[0040] Based on Example 1, a preferred embodiment of the intercepting well with sedimentation and separation function provided by this utility model is as follows: Figures 1 to 5 As shown: The buffer assembly 3 includes: a fixing groove 305 symmetrically opened on the top wall of the filter frame 2, a slide rod 301 fixedly connected to the inner wall of the fixing groove 305, and a slider 302 movably connected to the surface of the slide rod 301; a fixing spring 304 wound around the surface of the slide rod 301, with both ends of the fixing spring 304 fixedly connected to one side of the slider 302 and the inner wall of the fixing groove 305 respectively; and a buffer plate 303 fixedly connected to the bottom of the two sliders 302.
[0041] In this embodiment, when heavy rain causes excessive water flow impact inside the filter frame 2, the water flow first contacts the buffer plate 303, causing the buffer plate 303 to slide and drive the slider 302 to slide on the surface of the slide rod 301 to compress the fixed spring 304. This reduces the impact force of the water flow and prevents excessive impact force from causing collision damage to the filter frame 2 or damaging the connection between the filter frame 2 and the internal slide rail of the intercepting well body 1, which would make it inconvenient for the filter frame 2 to slide up and down.
[0042] In a further preferred embodiment of the present invention, a sliding structure is formed between the surfaces of the slider 302 and the slide bar 301, and the bottom end of the slider 302 is fixedly connected to the top end of the buffer plate 303 by bolts.
[0043] In this embodiment, the smoothness of the sliding of the buffer plate 303 is improved by utilizing the sliding of the slider 302 and the surface of the slider 301.
[0044] In a further preferred embodiment of this utility model, the buffer plate 303 is tilted at an angle of forty degrees to the vertical direction, and through slots are provided at equal intervals on the buffer plate 303.
[0045] In this embodiment, the buffer plate 303 with through grooves can be used to break the water flow into multiple streams after impact, which facilitates turbulence between the water flows and further reduces the impact force of the water flow.
[0046] The working principle of this utility model is as follows: First, the inlet pipe 4, the sludge discharge pipe 602, the drain pipe 7, and the overflow pipe 10 are connected to the external pipeline. Then, on sunny days or during light rain, the water flows through the inlet pipe 4 into the filter frame 2, where the filter frame 2 filters out large particles such as fallen leaves from the water. After that, the filtered water and some of the sludge in the water enter the intercepting well body 1 and descend by gravity. At this time, the valve on the overflow pipe 10 is opened to facilitate the discharge of this part of the water through the overflow pipe 10. At the same time, the sludge in the water will settle due to gravity and be guided by the guide platform 5 to flow from the sludge discharge hopper 604 into the settling tank 605 for storage. Meanwhile, the funnel-shaped sludge discharge hopper 604 can reduce the amount of sludge that is thrown to the outside of the settling tank 605.
[0047] When sludge needs to be discharged, the valve on the sludge discharge pipe 602 can be opened, and the servo motor 601 can be started to drive the spiral sludge discharge rod 603 to rotate, so that the sludge inside the sludge discharge trough 606 can be transported and discharged through the sludge discharge pipe 602. The inner wall of the settling tank 605 is inclined, which can guide the sludge and allow it to be transported smoothly into the sludge discharge trough 606, which is convenient for the subsequent spiral discharge of the spiral sludge discharge rod 603.
[0048] Meanwhile, during heavy rain, the water flow entering the filter frame 2 will have a large impact force. The water flow will first come into contact with the buffer plate 303, causing the buffer plate 303 to slide and drive the slider 302 to slide on the surface of the slide rod 301, compressing the fixed spring 304. At the same time, the sliding friction between the slider 302 and the slide rod 301 and the resistance of the buffer plate 303 moving in the water can consume the elastic potential energy of the fixed spring 304, thereby reducing the impact force of the water flow and preventing the excessive impact force from causing collision damage to the filter frame 2, or damaging the connection between the filter frame 2 and the internal slide rail of the intercepting well body 1, which would cause inconvenience to the subsequent up and down sliding of the filter frame 2.
[0049] Because too much water enters, the liquid level inside the intercepting well body 1 rises rapidly. Then, the small amount of mud and sand stirred up in the water is filtered again through the fine filter plate 9. The water filtered again can be discharged through the drain pipe 7. At the same time, the fine filter plate 9 can be removed for cleaning and unclogging by hooking the hanging ring on the fine filter plate 9 through external equipment at regular intervals. The filter frame 2 can also be raised by the hanging ring on the filter frame 2 to remove large particles such as fallen leaves inside the filter frame 2. Furthermore, a sliding rail is set on one side of the intercepting well body 1 to improve the stability of the filter frame 2 sliding up and down.
[0050] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.
[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
