Description

Technical Field

[0001] This utility model relates to the field of sedimentation tanks, and in particular to a uniform effluent system for a side-flow sedimentation tank. Background Technology

[0002] Sedimentation tanks are devices that purify water by removing suspended solids through sedimentation. Lateral flow sedimentation tanks are widely used due to their high sedimentation efficiency and small footprint. In a lateral flow sedimentation tank, water flows horizontally across inclined plates at the cross-section. After sedimentation by the inclined plates, the water enters the effluent zone and is then collected by the top overflow weir into the production channel. However, after sedimentation by the inclined plates, the water droplets are at the top of the effluent zone, resulting in uneven water flow along the tank depth. This manifests as a shorter flow path and larger flow volume at the top, and a longer flow path and smaller flow volume at the bottom. Consequently, the upper inclined plates experience high water volume and high load, while the lower inclined plates experience low water volume and low load, thus affecting the treatment effect of the lateral flow sedimentation tank.

[0003] To avoid uneven water flow and uneven load on the upper and lower inclined plates, perforated walls are usually installed in the effluent zone of the side flow sedimentation tank design to improve the uniformity of water flow across the cross section. However, because the effluent volume is uncontrollable and a long flow stabilization zone is required to ensure the sedimentation effect, it further increases the footprint and cost. Therefore, a uniform effluent system for side flow sedimentation tanks is needed to solve the above problems. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this device provides a side-flow sedimentation tank uniform water discharge system. This device effectively solves the problem of uneven water discharge between the upper and lower layers, and also has the advantage of controllable water discharge.

[0005] The purpose of this utility model is to provide a uniform water discharge system for a lateral flow sedimentation tank, including a sedimentation tank. The sedimentation tank has a sedimentation pool at its upper end and an inlet area at its rear end. Multiple sedimentation mechanisms are arranged horizontally inside the sedimentation pool. A water outlet chamber is located at the front end of the sedimentation pool and includes four water outlet sections. The four water outlet sections are arranged horizontally. Four water outlet pipes communicating with the sedimentation pool are embedded at the rear end of each of the four water outlet sections. The four water outlet pipes are arranged vertically. Water outlet mechanisms are slidably connected to the front ends of each of the four water outlet sections. A mounting frame is fixedly connected to the top of the sedimentation tank, and a driving mechanism is fixedly connected to the top of the mounting frame. The driving mechanism is connected to the water outlet mechanism.

[0006] Furthermore, the sedimentation mechanism includes a frame, with multiple flow-decelerating inclined plates fixedly connected to the inside of the frame to slow down the water flow.

[0007] Furthermore, the drive mechanism includes a drive motor, which is fixedly connected to one side of the mounting bracket. A drive shaft is rotatably connected to the inside of the mounting bracket. One end of the drive shaft passes through the mounting bracket and is fixedly connected to the output end of the drive motor. Multiple graded adjustment mechanisms are slidably connected to the surface of the drive shaft, and each graded adjustment mechanism is connected to a corresponding water outlet mechanism.

[0008] Furthermore, the water outlet mechanism includes four water outlet weir plates, which are longitudinally slidably connected to the inner front end of the corresponding water outlet section. Each of the four water outlet weir plates has a threaded hole at its top, and a threaded rod is threadedly connected to each of the threaded holes. The top of the threaded rod is rotatably connected to the mounting frame, and a driven bevel gear is coaxially fixedly connected to the top of the mounting frame. The driven bevel gear is connected to the corresponding grade adjustment mechanism.

[0009] Furthermore, the grading adjustment mechanism includes a sleeve, which is slidably connected to the radial surface of the drive shaft. One end of the sleeve is coaxially fixedly connected to a driving bevel gear, which meshes with the corresponding driven bevel gears. Connecting blocks are slidably connected to the radial surface of the sleeve, and an electric push rod is fixedly connected to one side of the connecting block. The electric push rod is fixedly connected to the top of the mounting bracket.

[0010] Furthermore, multiple water collection troughs are provided parallel to each other at the bottom of the sedimentation tank, and the multiple water collection troughs are located at the bottom of the corresponding sedimentation mechanism. Multiple drain outlets are provided on one side of the sedimentation tank, which are connected to the corresponding water collection troughs.

[0019] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0020] according to Figures 1 to 4 As shown, a side-flow sedimentation tank uniform effluent system includes a sedimentation tank 1, a sedimentation pool 2 at the upper end of the sedimentation tank 1, an inlet area 3 at the rear end of the sedimentation pool 2, multiple sedimentation mechanisms 4 arranged laterally inside the sedimentation pool 2, an effluent cavity at the upper end of the sedimentation tank 1 located at the front end of the sedimentation pool 2, the effluent cavity including four effluent sections 6, the four effluent sections 6 being distributed laterally, four effluent pipes 5 connected to the sedimentation pool 2 being embedded at the rear end of the four effluent sections 6, the four effluent pipes 5 being distributed longitudinally, and effluent mechanisms 7 being slidably connected longitudinally to the front end of the four effluent sections 6, a mounting frame 10 being fixedly connected to the top of the sedimentation tank 1, a drive mechanism 8 being fixedly connected to the top of the mounting frame 10, and the drive mechanism 8 being connected to the effluent mechanism 7.

[0021] In practical implementation, the effluent chamber and sedimentation tank 2 are opened from front to back on the top of the sedimentation tank 1. Multiple parallel sedimentation mechanisms 4 within the sedimentation tank 2 can be used to increase the sedimentation area and improve sedimentation efficiency. The four effluent pipes 5 are horizontal pipes, longitudinally distributed on the partition between the sedimentation tank 2 and the effluent chamber. The inlet ends of the four effluent pipes 5 are located inside the sedimentation tank 2, and the outlet ends are located in their respective effluent zones 6. The upper effluent pipe 5 is used for effluent from the upper layer of water in the sedimentation tank 2, while the lower effluent pipe 5 is used for... The first outlet pipe is for the bottom layer of water in sedimentation tank 2, and the other two outlet pipes 5 are for the middle layer of water in sedimentation tank 2. The water in sedimentation tank 2 flows into the corresponding outlet section 6 through the corresponding outlet pipes 5. The front end of the four corresponding outlet sections 6 is equipped with an adjustable height outlet mechanism 7. The four outlet mechanisms 7 are controlled by the drive mechanism 8. By changing the height of the outlet mechanism 7 at the front end of the corresponding outlet section 6, the water output of the outlet section 6 can be controlled respectively, so as to achieve the effect of adjusting the water output of the corresponding outlet section 6 according to the situation.

[0022] Furthermore, the sedimentation mechanism 4 includes a frame 41, and a plurality of flow-slowing inclined plates 42 for slowing down the water flow are fixedly connected to the inner side of the frame 41.

[0023] In practice, multiple inclined flow-slowing plates 42 are fixedly connected to the inner side of the frame 41. The inclined flow-slowing plates 42 can not only allow particles to slide down naturally, but also reduce the flow rate of the water, increase the sedimentation time of the water, and enhance the sedimentation effect.

[0024] Furthermore, the drive mechanism 8 includes a drive motor 81, which is fixedly connected to one side of the mounting frame 10. A drive shaft 82 is rotatably connected to the inner side of the mounting frame 10. One end of the drive shaft 82 passes through the mounting frame 10 and is fixedly connected to the output end of the drive motor 81. Multiple graded adjustment mechanisms 9 are slidably connected to the surface of the drive shaft 82. The graded adjustment mechanisms 9 are respectively connected to the corresponding water outlet mechanism 7.

[0025] In practical implementation, a horizontal plate is fixedly connected to one side of the mounting bracket 10, and the drive motor 81 is fixedly connected to the top of the horizontal plate. The output end of the drive motor 81 is fixedly connected to the drive shaft 82 coaxially. At the same time, four graded adjustment mechanisms 9 are slidably connected to the surface of the drive shaft 82. The four graded adjustment mechanisms 9 are respectively connected to the corresponding water outlet mechanism 7. In use, the drive motor 81 controls the drive shaft 82 to rotate. When the shaft rotates, the graded adjustment mechanism 9 controls the height adjustment of the corresponding water outlet mechanism 7, thereby realizing the control of the water output of the corresponding water outlet zone 6, which improves practicality.

[0026] Furthermore, the water outlet mechanism 7 includes four water outlet weir plates 71. The four water outlet weir plates 71 are longitudinally slidably connected to the inner front end of the corresponding water outlet section 6. The top of each of the four water outlet weir plates 71 is provided with a threaded hole 72. A threaded rod 73 is threadedly connected to each of the threaded holes 72. The top of the threaded rod 73 is rotatably connected to the mounting frame 10, and the top of the threaded rod 73 extends to the top of the mounting frame 10 and is coaxially fixedly connected to a driven bevel gear 74. The driven bevel gear 74 is connected to the corresponding grade adjustment mechanism 9.

[0027] In practical implementation, the four outlet sections 6 at the front end of the sedimentation tank 1 are each provided with a longitudinal groove. The four outlet weir plates 71 are slidably connected longitudinally in the longitudinal grooves at the front end of the corresponding outlet sections 6. The top of each of the four outlet weir plates 71 is threadedly connected with a threaded rod 73. The top of the threaded rod 73 extends to the top of the mounting frame 10 and is coaxially fixedly connected with a driven bevel gear 74. The driven bevel gear 74 is connected to the corresponding grading adjustment mechanism 9. The drive shaft 82 is rotated by the drive motor 81. When the drive shaft 82 rotates, the corresponding grading adjustment mechanism 9 is controlled to make the corresponding driven bevel gear 74 rotate axially. The rotation of the driven bevel gear 74 drives the threaded rod 73 to rotate axially. The rotation of the threaded rod 73 adjusts the depth of the bottom end of the threaded rod 73 in the threaded hole 72, thereby adjusting the height of the corresponding outlet weir plate 71. The water output of the corresponding outlet section 6 is adjusted by changing the height of the outlet weir plate 71.

[0028] Furthermore, the graded adjustment mechanism 9 includes a sleeve 93, which is slidably connected to the radial surface of the drive shaft 82. One end of the sleeve 93 is coaxially fixedly connected to a drive bevel gear 94, which meshes with the corresponding driven bevel gear 74. Connecting blocks 92 are slidably connected to the radial surface of the sleeve 93, and an electric push rod 91 is fixedly connected to one side of the connecting block 92. The electric push rod 91 is fixedly connected to the top of the mounting bracket 10.

[0029] In practical implementation, a semi-circular block is provided on the inner side of the sleeve 93, and a semi-circular groove is provided on the surface of the drive shaft 82. The sleeve 93 is slidably connected to the drive shaft 82 through the semi-circular block and the semi-circular groove. The semi-circular block and the semi-circular groove enable the drive shaft 82 to rotate axially, thereby driving the sleeve 93 to rotate axially. The rotation of the sleeve 93 drives the active bevel gear 94 to rotate, which in turn drives the driven bevel gear 74 meshing with the active bevel gear 94 to rotate, thus achieving the purpose of controlling and adjusting the height of the outlet weir plate 71. At the same time, in order to achieve individual adjustment of the height of each outlet weir plate 71, the electric push rod 91 extends to push the connecting block 92 to move laterally. When the connecting block 92 moves to the right, the connecting block 92 drives... Sleeve 93 and drive bevel gear 94 move synchronously to the right. At this time, drive bevel gear 94 meshes with driven bevel gear 74, thereby controlling the rotation of threaded rod 73. Conversely, when electric push rod 91 retracts, it drives connecting block 92 to slide laterally in the opposite direction. When connecting block 92 moves in the opposite direction, it drives sleeve 93 and drive bevel gear 94 to move synchronously. At this time, drive bevel gear 94 disengages from the corresponding driven bevel gear 74. By controlling the extension and retraction of electric push rod 91 corresponding to water outlet weir plate 71, the meshing and disengagement of the corresponding drive bevel gear 94 and driven bevel gear 74 can be achieved. This allows the height of each water outlet weir plate 71 to be controlled individually when drive shaft 82 rotates, thus achieving the purpose of individually adjusting the water output of each water outlet section 6.

[0030] Furthermore, multiple water collection troughs 21 are provided parallel to each other at the bottom of the sedimentation tank 2. The multiple water collection troughs 21 are located at the bottom of the corresponding sedimentation mechanism 4. Multiple drain outlets 22 are provided on one side of the sedimentation tank 1, which are respectively connected to the corresponding water collection troughs 21.

[0031] In specific implementation, the water collection tank 21 can be set as V-shaped. The sedimentation mechanism 4 can be used to settle the particulate matter in the water into the water collection tank 21. The V-shaped water collection tank 21 can be used to collect the settled particulate matter to the bottom of the water collection tank 21 and then discharge it through the corresponding drain outlet 22, which is convenient for cleaning and discharging the sediment.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
