Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ion flotation water distribution device. Background Technology

[0002] In the ion flotation water treatment system, the water distribution mechanism consists of a multi-channel regulating water distribution pipe, a multi-chamber water distribution hopper, and a rectifier grid. The flow rate is uniform by manually adjusting the valve plate opening, then the water flow is dispersed through the multi-chamber, and finally the water is distributed by the grid resistance, so that the water entering the tank is uniform.

[0003] A published Chinese patent, publication number CN220351775U, discloses a circular shallow ion flotation water distribution mechanism, belonging to the technical field of water distribution mechanisms. This circular shallow ion flotation water distribution mechanism includes a multi-channel regulating water distribution pipe, a multi-chamber water distribution hopper, and a rectifying and balancing grid. Both the multi-channel regulating water distribution pipe and the rectifying and balancing grid are installed on the multi-chamber water distribution hopper. In use, the opening of each conical valve plate is adjusted according to the flow pattern of each chamber of the multi-chamber water distribution hopper to form a primary balanced water distribution. Water from the outlet branch pipe flows annularly along the surface of the conical valve plate into the first, second, and third chambers, ensuring that no localized high flow rates or high velocities are formed within the chambers, thus forming a secondary water distribution. Water from the multi-chamber water distribution hopper undergoes resistance-based water distribution through the rectifying and balancing grid, forming a tertiary water distribution. The water distribution mechanism disclosed in this patent, when in operation, is prone to air resistance in the water distribution pipe due to the generation and release of air bubbles during the air flotation process, which disrupts the uniformity of water flow, hinders the normal distribution of water flow, and causes sudden changes in the inlet flow rate. Furthermore, the water distribution mechanism cannot be adaptively adjusted, which can easily cause local short flow and thus lead to uneven water distribution.

[0004] Therefore, it is necessary to design an ion flotation water distribution device with automatic venting and uniform water distribution. Utility Model Content

[0005] The purpose of this invention is to provide an ion flotation water distribution device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an ion flotation water distribution device, comprising a water distribution pipe, a water distribution hopper, and a rectifier grid; the water distribution pipe is disposed above the water distribution hopper, and the rectifier grid is installed on one side of the water distribution hopper;

[0007] The water distribution pipe includes a main inlet pipe, a branch inlet pipe, a branch pipe, and an outlet pipe connected in sequence at the lower end of the branch pipe;

[0008] The diversion pipe is equipped with a flow regulating component and an air vent valve. The flow regulating component includes a lead screw, a water outlet valve plate, and a servo motor. One end of the lead screw passes through the water outlet pipe and is connected to the water outlet valve plate, and the other end is connected to the output end of the servo motor. A water flow sensor is provided on the water outlet valve plate.

[0009] According to the above technical solution, the exhaust valve includes a housing, an air inlet pipe, a float, a plug rod, an exhaust pipe, and a spring. The air inlet pipe is located at the bottom of the housing, the float is located inside the housing, one end of the plug rod is connected to the float, and the other end of the plug rod is sealed to the exhaust pipe. The spring is sleeved at the connection between the plug rod and the exhaust pipe, and the end of the exhaust pipe away from the plug rod passes through the outside of the housing.

[0010] According to the above technical solution, the water distribution bucket is provided with several flow equalization chambers corresponding to the water outlet pipe.

[0011] According to the above technical solution, the connection between the main water inlet pipe and the branch water inlet pipe is made by a flange, and a number of bolts are connected equidistantly around the circumference of the flange.

[0012] According to the above technical solution, a positioning plate is provided above the outlet valve plate of the lead screw, a positioning cylinder is threadedly fitted below the servo motor of the lead screw, the servo motor is installed on the top of the positioning cylinder, and the bottom of the positioning cylinder is connected to the diversion pipe.

[0013] According to the above technical solution, the rectifier grille includes a mounting frame and a V-shaped grille, and a plurality of the V-shaped grilles are arranged equidistantly on the mounting frame.

[0014] According to the above technical solution, the flow regulating component is provided in multiple ways, and an exhaust valve is provided between two adjacent flow regulating components.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] (1) By setting up a flow regulating component and a water flow sensor, it is possible to accurately regulate the water flow of the outlet pipe. The water flow sensor can monitor the water flow of the outlet pipe in real time. When the water flow does not meet the preset requirements, the control system controls the servo motor to drive the screw to rotate, which drives the outlet valve plate to move up and down to change the opening of the outlet pipe, thereby quickly adjusting the water flow, ensuring that the water output of each outlet pipe is uniform and stable, avoiding local short flow, resulting in uneven water output, improving the water distribution accuracy of the water distribution device, and thus ensuring the treatment effect of ion flotation.

[0017] (2) By setting an exhaust valve, the gas in the water distribution pipe can be discharged in time, avoiding the accumulation of gas in the pipe that affects the stability of the water flow and the uniformity of water distribution. When there is gas in the water distribution pipe, the gas will enter the shell through the air inlet pipe, causing the water level in the shell to drop, the float to move down, the spring to bend, the plug rod to separate from the exhaust pipe, and the gas to be discharged through the exhaust pipe. When the gas is discharged, the float rises under the action of buoyancy, the spring returns to its original position, and the plug rod is re-sealed with the exhaust pipe, ensuring the smoothness of the water flow in the water distribution pipe and further optimizing the water distribution effect.

[0023] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] This utility model provides a technical solution: a water distribution device for ion flotation, including a water distribution pipe 10, a water distribution bucket 20 and a rectifier grid 30; the water distribution pipe 10 is arranged above the water distribution bucket 20 and the rectifier grid 30 is installed on one side of the water distribution bucket 20.

[0025] The water distribution pipe 10 includes a main water inlet pipe 11, a branch water inlet pipe 12, a branch pipe 13, and an outlet pipe 14 connected in sequence to the lower end of the branch pipe 13.

[0026] The diversion pipe 13 is equipped with a flow regulating component 40 and an exhaust valve 50. The flow regulating component 40 includes a lead screw 41, a water outlet valve plate 42 and a servo motor 43. One end of the lead screw 41 passes through the water outlet pipe 14 and is connected to the water outlet valve plate 42, and the other end is connected to the output end of the servo motor 43. A water flow sensor 421 is provided on the water outlet valve plate 42.

[0027] Through this technical solution, the main inlet pipe 11 transports sewage to the diversion pipe 13 via the inlet branch pipe 12, and then discharges it into the water distribution hopper 20 through the outlet pipe 14 on the lower surface of the diversion pipe 13. The flow rectifier 30 on one side of the water distribution hopper 20 further optimizes the water flow. The flow regulating component 40 and the air vent valve 50, which are set at intervals on the diversion pipe 13, cooperate with each other. The servo motor 43 in the flow regulating component 40 drives the lead screw 41 to move the outlet valve plate 42. Combined with the water flow sensor 421 on the outlet valve plate 42, the opening of the outlet pipe 14 can be adjusted in real time and accurately to ensure that the water volume of each outlet pipe 14 is uniform. The air vent valve 50 can discharge the gas in the pipe in time to avoid water flow turbulence, thereby improving the stability and treatment efficiency of the ion flotation system.

[0028] Furthermore, the exhaust valve 50 includes a housing 51, an intake pipe 52, a float 53, a plug rod 54, an exhaust pipe 55, and a spring 56. The intake pipe 52 is located at the bottom of the housing 51, the float 53 is located inside the housing 51, one end of the plug rod 54 is connected to the float 53, and the other end of the plug rod 54 is sealed to the exhaust pipe 55. The spring 56 is sleeved at the connection between the plug rod 54 and the exhaust pipe 55, and the end of the exhaust pipe 55 away from the plug rod 54 extends through the outside of the housing 51.

[0029] With this technical solution, the air inlet pipe 52 at the bottom of the shell 51 can introduce gas from the diversion pipe 13 into the shell 51. When gas accumulates in the shell 51, the float 53 drops with the water level, the spring 56 bends, and the plug rod 54 is separated from the exhaust pipe 55, thereby opening the exhaust pipe 55. The gas is discharged through the exhaust pipe 55. After the gas is completely discharged, the float 53 rises under the action of buoyancy, the plug rod 54 is re-sealed and connected to the exhaust pipe 55, and the spring 56 is reset, effectively preventing water flow turbulence caused by gas accumulation in the water distribution pipe 10.

[0030] Furthermore, the water distribution hopper 20 is provided with several flow equalization chambers 21 corresponding to the water outlet pipe 14;

[0031] Through this technical solution, the flow equalization chamber 21 on the water distribution hopper 20 can be precisely aligned with the water outlet pipe 14, so that the sewage discharged from each water outlet pipe 14 first enters the corresponding flow equalization chamber 21. The flow equalization chamber 21 can buffer and equalize the incoming water flow, allowing the water flow to form a stable flow state in the chamber before flowing out of the water distribution hopper 20, thereby further ensuring the uniformity of water distribution and laying a good foundation for the subsequent rectification treatment of the water flow by the rectification grid 30.

[0032] Furthermore, the connection between the main water inlet pipe 11 and the branch water inlet pipe 12 is made by a flange 15, and a number of bolts 151 are equidistantly connected around the circumference of the flange 15.

[0033] Through this technical solution, the connection method of flange 15 and bolt 151 can make the connection between the main water inlet pipe 11 and the branch water inlet pipe 12 fit tightly, effectively preventing sewage leakage and ensuring the water circuit's sealing. Secondly, the flange 15 facilitates the installation and disassembly of the main water inlet pipe 11 and the branch water inlet pipe 12, providing convenience for the inspection, maintenance, and component replacement of the device.

[0034] Furthermore, a positioning plate 411 is provided above the outlet valve plate 42 on the lead screw 41, and a positioning cylinder 412 is threadedly fitted below the servo motor 43 on the lead screw 41. The servo motor 43 is installed on the top of the positioning cylinder 412, and the bottom of the positioning cylinder 412 is connected to the diversion pipe 13.

[0035] Through this technical solution, the positioning plate 411 on the lead screw 41 can limit and guide the movement direction of the lead screw 41, preventing the lead screw 41 from deviating when driving the water outlet valve plate 42 to move, ensuring that the water outlet valve plate 42 can accurately adjust the opening of the water outlet pipe 14. The positioning cylinder 412 not only provides a stable installation base for the servo motor 43, allowing the servo motor 43 to remain stable during operation, but also further constrains the rotation and movement of the lead screw 41, reducing shaking and making the entire flow adjustment process more stable and reliable.

[0036] Furthermore, the rectifier grille 30 includes a mounting frame 31 and a V-shaped grille 32, with a plurality of V-shaped grilles 32 arranged equidistantly on the mounting frame 31.

[0037] Through this technical solution, the V-shaped grid 32 can uniformly cut and guide the water flow, breaking up the turbulence and vortices in the water flow, so that the water flow forms a stable and uniform flow state after passing through the rectifier grid 30.

[0038] Furthermore, multiple flow control components 40 are provided, and an exhaust valve 50 is provided between two adjacent flow control components 40.

[0039] Through this technical solution, multiple flow control components 40 can adjust the water flow rate in stages according to actual needs, and multiple air vents 50 can promptly discharge the gas in the pipeline to avoid the air pressure affecting the water flow efficiency. The combination of the two improves the system's flexibility in controlling the water flow.

[0040] Working principle: Sewage first enters the main inlet pipe 11, and is then transported to the branch inlet pipe 12. From the branch inlet pipe 12, it flows into the diversion pipe 13. The water in the diversion pipe 13 is discharged through the outlet pipe 14 on the lower surface. During this process, the water flow sensor 421 monitors the water flow of the outlet pipe 14 in real time. The servo motor 43 in the flow regulating component 40 drives the lead screw 41 to move the outlet valve plate 42. Combined with the water flow sensor 421 on the outlet valve plate 42, the opening of the outlet pipe 14 can be adjusted in real time and accurately to ensure that the water output of each outlet pipe 14 is uniform.

[0041] Meanwhile, the air inlet pipe 52 at the bottom of the shell 51 can introduce the gas in the diversion pipe 13 into the shell 51. When the gas accumulates in the shell 51, the float 53 drops with the water level, the spring 56 bends, and the plug rod 54 is separated from the exhaust pipe 55, thereby opening the exhaust pipe 55. The gas is discharged through the exhaust pipe 55. After the gas is completely discharged, the float 53 rises under the action of buoyancy, the plug rod 54 is re-sealed and connected to the exhaust pipe 55, and the spring 56 is reset.

[0042] The sewage discharged from the outlet pipe 14 enters the corresponding flow equalization chamber 21 on the water distribution hopper 20. After the chamber buffers and equalizes the water flow, the water flows to the flow straightening grid 30. The V-shaped grid 32 on the mounting bracket 31 cuts and guides the water flow evenly, breaking up turbulence and vortices, and finally making the water flow form a stable and uniform flow state.
