Description

Technical Field

[0001] This utility model relates to the field of tailwater tank technology, and more specifically, to a tailwater tank with a buffering function. Background Technology

[0002] The purpose of the tailwater tank is to temporarily store the treated tailwater and then transport it to the water-using stage through pumps and pipelines, eliminating the time mismatch between water production and water use, and ensuring that all tailwater is reused, does not overflow, and is not discharged.

[0003] Structurally, the tailwater tank mainly consists of a tank body, an inlet pipe, and an outlet pipe, with a collection tank at the lowest point to facilitate the centralized discharge of sedimented impurities. However, the inlet pipe of existing tailwater tanks usually extends directly into the bottom of the tank body. When the tailwater enters the bottom of the tank body from the inlet pipe, it has a large impact force, which easily stirs up the impurities deposited at the bottom, causing the settled impurities to be resuspended in the water. This disturbance not only affects the stable extraction of the outlet pipe and causes fluctuations in the delivery flow, but also causes impurities to be discharged with the tailwater, reducing the water quality of the water used. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, the present invention provides a tailwater tank with a buffer function, including a tank body, a manifold, an inlet pipe and several branch pipes.

[0006] The manifold is installed inside the lower side of the tank. The manifold has a manifold cavity inside and several through holes on its circumference. The output direction of the through holes is inclined upward. The inlet pipe is installed in the tank and passes through the manifold. Several branch pipes are connected to the circumference of the inlet pipe and the lower side of the manifold. The tailwater is buffered and diverted into the manifold cavity through the inlet pipe and several branch pipes, and then buffered and diverted into the tank through several through holes at an inclined upward.

[0007] The tailwater tank with buffering function proposed in this utility model reduces the initial impact kinetic energy by setting multiple branch pipes at the lower end of the inlet pipe, which transforms the single-point inlet into multi-directional low-speed diversion. After the tailwater enters the confluence chamber through the branch pipes, it is initially energy-dissipated and buffered, and then output through the circumferentially inclined upward through hole, which avoids the tailwater directly hitting the bottom of the tank and reduces the disturbance to the impurities deposited at the bottom. The synergistic effect of the multiple buffering structures ensures the stability and reliability of tailwater reuse.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0012] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 4 A tailwater tank with a buffer function is provided. The tailwater tank is used to store tailwater. The tailwater tank includes a tank body 100, a manifold 200, an inlet pipe 500 and several branch pipes 600.

[0014] The manifold 200 is installed on the lower side of the inside of the tank 100. The manifold 200 has a manifold cavity 300 inside. Several through holes 400 are opened on the circumferential side of the manifold 200. The output direction of the several through holes 400 is inclined upward. The liquid inlet pipe 500 is installed on the tank 100 and passes through the manifold 200. Several branch pipes 600 are connected to the circumferential side of the liquid inlet pipe 500 and the lower side of the manifold 200. The tailwater is buffered and diverted into the manifold cavity 300 through the liquid inlet pipe 500 and several branch pipes 600, and then buffered and diverted into the tank 100 from the several through holes 400 at an inclined upward.

[0015] In this embodiment: A tailwater tank with a buffer function is used to store tailwater. The tailwater tank includes a tank body 100, a manifold 200, an inlet pipe 500, and several branch pipes 600.

[0016] The manifold 200 is installed on the lower inner side of the tank 100. The manifold 200 has a manifold cavity 300 inside. Several through holes 400 are opened on the circumferential side of the manifold 200. The output direction of the several through holes 400 is inclined upward. Optionally, the manifold 200 is centrally located inside the tank 100, so that the distance between the through holes 400 and the inner side wall of the tank 100 is the same, and there is space between the lower side of the manifold 200 and the inner bottom of the tank 100 to provide a place for the sedimentation of impurities.

[0017] The inlet pipe 500 is installed on the tank 100 and passes through the manifold 200; optionally, the axis of the inlet pipe 500 coincides with the axis of the tank 100, and the inlet pipe 500 is used to transport tailwater to the bottom of the manifold 200.

[0018] Several branch pipes 600 are connected to the circumferential side of the inlet pipe 500 and the lower side of the manifold 200; the several branch pipes 600 are used to divert the tail water conveyed by the inlet pipe 500 into the manifold 300.

[0019] The tailwater is buffered and diverted into the manifold 300 via the inlet pipe 500 and several branch pipes 600, and then diverted into the tank 100 at an angle upwards through several through holes 400. Through the setting of multiple slow flow, the tailwater can be stably delivered into the tank 100, reducing the disturbance to the tailwater already stored in the tank 100, and also reducing the disturbance to the impurities deposited at the bottom.

[0020] Please see Figure 2 In some embodiments of this utility model, optionally, the number of branch pipes 600 is 2 to 6, and they are distributed around the circumference of the liquid inlet pipe 500.

[0021] In this embodiment: The number of branch pipes 600 is 2 to 6, and they are distributed around the circumference of the inlet pipe 500. They are used to convert the single-pipe input of the inlet pipe 500 into multi-directional diversion, effectively reducing the single-point flow velocity and impact force. Optionally, the branch pipes 600 are evenly distributed so that the force inside the manifold 300 is uniform and the buffer is stable.

[0022] Please see Figure 2 In some embodiments of this utility model, optionally, the manifold 200 is a hollow frustum-shaped structure with an upper area smaller than the lower area.

[0023] In this embodiment: The manifold 200 is a hollow frustum-shaped disc with an upper area smaller than the lower area. The circumferential side of the hollow frustum-shaped manifold 200 is sloped, which causes the through holes 400 on the circumferential side to tilt upward. The tailwater in the manifold 300 is sprayed obliquely upward through the through holes 400 and then diffuses along the tank wall of the tank body 100, avoiding direct impact to the bottom of the tank, further reducing the impact force, reducing disturbance to the sediment at the bottom, and ensuring the stability of the liquid output.

[0024] Optionally, the busbar 200 adopts a split structure for splicing and is connected by bolts, which facilitates manufacturing and assembly, and also makes it easy to disassemble and clean during maintenance.

[0025] Please see Figure 2 In some embodiments of this utility model, optionally, the tailwater tank further includes a diffusion cone 700, which is installed in the through hole 400, and the diameter of the port of the diffusion cone 700 away from the through hole 400 is larger than the diameter of the through hole 400.

[0026] In this embodiment: The tailwater tank also includes a diffuser cone 700, which is installed in the through hole 400. The diameter of the port of the diffuser cone 700 away from the through hole 400 is larger than the diameter of the through hole 400. The diffuser cone 700 has a gradually expanding structure. When the tailwater passes through the diffuser cone 700, the flow cross section gradually increases and the flow velocity decreases accordingly, further weakening the impact force of the outflowing water and making the water flow more gently diffuse upward into the tank body 100.

[0027] Please see Figure 3 In some embodiments of this utility model, optionally, the tailwater tank further includes a corrugated pipe 800, which is installed at the lower end of the inlet pipe 500.

[0028] In this embodiment: The tailwater tank also includes a bellows 800, which is installed at the lower end of the inlet pipe 500. Utilizing the expandable and deformable characteristics of the bellows 800, it absorbs the water hammer impact and pulsating pressure when liquid enters from the lower end of the inlet pipe 500, thus playing a flexible buffering role.

[0029] Please see Figure 4 In some embodiments of this utility model, optionally, the top of the manifold 200 is provided with a through groove 900, and the tailwater tank also includes a diversion cover 110 and a rubber ring 120.

[0030] The diversion hood 110 is located inside the through channel 900 and above the branch pipe 600; the rubber ring 120 is installed between the manifold 200 and the diversion hood 110; wherein, the diversion hood 110 is used to evenly distribute the tailwater output from the branch pipe 600 upward, and the rubber ring 120 is used to buffer the impact force on the diversion hood 110.

[0031] In this embodiment: The top of the manifold 200 is provided with a through groove 900, and the tailwater tank also includes a diversion cover 110 and a rubber ring 120.

[0032] The diversion hood 110 is located inside the through channel 900 and above the branch pipe 600; optionally, the diversion hood 110 is a partial spherical shell type, which has the function of dispersing water flow and preventing water flow from concentrating and impacting the top of the confluence cavity 300.

[0033] The rubber ring 120 is installed between the manifold 200 and the drain cover 110; optionally, the rubber ring 120 and the drain cover 110 are connected by bonding with modified epoxy underwater adhesive.

[0034] The drainage hood 110 is used to evenly distribute the tailwater output from the branch pipe 600 upwards, and the rubber ring 120 is used to buffer the impact force on the drainage hood 110; that is, the drainage hood 110 evenly disperses the tailwater output from the branch pipe 600 along the spherical surface, which can avoid concentrated impact; the rubber ring 120 absorbs kinetic energy through elastic deformation, plays a flexible buffering role, and weakens the disturbance to the water flow in the manifold 300.

[0035] Furthermore, the lower diameter of the drainage cover 110 is larger than the diameter of the through groove 900. When the drainage cover 110 is moved to the highest position, it will abut against the through groove 900, which will play a limiting and protective role, preventing the rubber ring 120 from being stretched excessively and protecting the rubber ring 120.

[0036] Please see Figure 3 In some embodiments of this utility model, optionally, the tailwater tank also includes a grid plate 130, which is installed inside the tank body 100. There are two grid plates 130, which are respectively distributed above and below the manifold 200.

[0037] In this embodiment: The tailwater tank also includes a grid plate 130, which is installed inside the tank body 100. There are two grid plates 130, which are distributed above and below the manifold 200, respectively.

[0038] The upper grid plate 130 is used to further disperse the slowly flowing tailwater upwards, and the lower grid plate 130 is used to further disperse the slowly flowing tailwater downwards, further ensuring the stable water flow inside the tank 100.

[0039] Please see Figure 1 In some embodiments of this utility model, optionally, the tailwater tank further includes an outlet pipe 140, which is installed on the tank body 100, and the depth to which the outlet pipe 140 extends into the tank body 100 is less than the depth to which the inlet pipe 500 extends into the tank body 100.

[0040] In this embodiment: The tailwater tank also includes an outlet pipe 140, which is installed in the tank body 100. The depth to which the outlet pipe 140 extends into the tank body 100 is less than the depth to which the inlet pipe 500 extends into the tank body 100. Furthermore, the lower end of the outlet pipe 140 is located on the upper side of the upper grid plate 130 to avoid the disturbance zone of the water flow, draw water from the relatively calm upper water area, improve the reliability of the transportation, and also prevent bottom sediment impurities from being sucked in.

[0041] Optionally, the tank 100 may also be equipped with conventional structures such as manholes, thermometers, vent valves, drain valves, level gauges, and overflow pipes to facilitate daily operation and maintenance and safety management. Among them, the manholes facilitate personnel to enter the tank for inspection and cleaning; the thermometers are used to monitor water temperature changes; the vent valves balance the air pressure inside the tank 100 to prevent the generation of negative or overpressure; the drain valves are located at the bottom of the tank to periodically discharge sediment and impurities; the level gauges display the water level inside the tank in real time; and the overflow pipes automatically drain when the liquid intake is excessive to prevent overflow.

[0042] In one embodiment, the workflow for storing and discharging wastewater through this wastewater tank is as follows: The tailwater is transported downward through the inlet pipe 500. The corrugated pipe 800 at the lower end of the inlet pipe 500 first absorbs the water hammer impact and pulsating pressure. After the tailwater reaches the lower end of the inlet pipe 500, it is evenly distributed and diverted around the circumference through 2 to 6 branch pipes 600. The single-point inlet is transformed into multi-directional low-speed diversion, and the kinetic energy is reduced. The tailwater output from each branch pipe 600 impacts the diversion hood 110 upward. The spherical shell structure of the diversion hood 110 evenly disperses the concentrated water flow around the circumference. The rubber ring 120 deforms elastically and absorbs the residual impact kinetic energy.

[0043] The dispersed tailwater enters the manifold 300 for initial energy dissipation and then exits through several upward-sloping through-holes 400 on the circumference of the manifold 200. The diffuser cone 700 gradually increases the flow cross-section and further reduces the flow velocity. The water flow spreads gently upward along the inner wall of the tank 100. The water flow is dispersed again by the grid plate 130 and finally flows smoothly into the tank 100, reducing disturbance to the bottom sediment and maintaining stable sedimentation.

[0044] When water needs to be drawn, the water pump draws the tailwater from the tank 100 through the outlet pipe 140. Since the end of the outlet pipe 140 that extends into the tank 100 is in a relatively calm water area above the water flow disturbance zone, it avoids sucking in the bottom sediment impurities. The tailwater is stably transported to the water-using stage through the outlet pipe 140.
