Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-efficiency hydrocyclone reflux device. Background Technology
[0002] In current mine water treatment processes, mine wastewater is first collected in a regulating tank and then pumped to a high-efficiency hydrocyclone for purification. The treated water then flows directly into a fire-fighting water tank for use in underground production and dust suppression. To ensure water quality, a turbidity meter is installed on the outlet pipe of the high-efficiency hydrocyclone to monitor the turbidity of the effluent in real time. Operators must closely monitor the turbidity index, and if the water quality fails to meet the standards for underground reuse or discharge, the pump must be stopped to prevent substandard water from continuing to enter the system.
[0003] According to the description of patent CN214299574U, in order to solve the problem of substandard water quality, a wastewater return device and valve control unit are introduced to redirect substandard water back to the equalization tank for further treatment. However, this approach has certain shortcomings: when the substandard water returns to the equalization tank, it mixes with untreated wastewater, reducing the overall system's treatment efficiency, because this portion of water has actually undergone one treatment process, yet the results of this initial treatment are not effectively utilized. Utility Model Content
[0004] The purpose of this utility model is to provide a high-efficiency hydrocyclone reflux device in order to solve the technical problems mentioned in the background art.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A high-efficiency hydrocyclone reflux device includes an equalization tank, a booster pump, a coagulant, a high-efficiency hydrocyclone, and a fire sprinkler tank. The equalization tank includes a mine water tank and a reflux tank. The outlets of the mine water tank and the reflux tank are connected to U-shaped pipes. The outlet of the U-shaped pipes is connected to the inlet of the booster pump. The outlet of the booster pump is connected to the inlet of the coagulant. The outlet of the coagulant is connected to the inlet of the high-efficiency hydrocyclone. The first outlet of the high-efficiency hydrocyclone is connected to the reflux tank through a reflux pipe. The second outlet of the high-efficiency hydrocyclone is connected to the fire sprinkler tank through an outlet pipe. Valve control units for controlling the liquid flow direction are installed on the U-shaped pipe, the reflux pipe, and the outlet pipe.
[0007] As a further description of the above technical solution:
[0008] The valve control unit includes a PLC control system, an online turbidity meter, a first solenoid valve, and a second solenoid valve. The online turbidity meter, the first solenoid valve, and the second solenoid valve are electrically connected to the PLC control system. The first solenoid valve is located at the inlet of the return pipe, and the online turbidity meter and the second solenoid valve are located on the upper and lower sides of the connection between the outlet pipe and the return pipe, respectively.
[0009] As a further description of the above technical solution:
[0010] The valve control unit also includes a liquid level sensor, a third solenoid valve, and a fourth solenoid valve. The liquid level sensor is located at the bottom of the return tank, and the third and fourth solenoid valves are respectively installed at the two inlets of the U-shaped tube. The liquid level sensor, the third solenoid valve, and the fourth solenoid valve are electrically connected to the PLC control system.
[0011] As a further description of the above technical solution:
[0012] The inlet of the booster pump is connected to the outlet of the U-shaped pipe via a first connecting pipe, the outlet of the booster pump is connected to the inlet of the coagulant via a second connecting pipe, and the outlet of the coagulant is connected to the inlet of the high-efficiency hydrocyclone via a third connecting pipe.
[0013] As a further description of the above technical solution:
[0014] The mine water tank is fixedly connected to an inlet pipe.
[0015] As a further description of the above technical solution:
[0016] The high-efficiency hydrocyclone has a sludge outlet on its bottom side.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: the water that has undergone initial treatment but does not meet the standards is returned to the return pool. Under the action of the booster pump, the water that has undergone initial treatment but does not meet the standards in the return pool is treated again by the coagulant and the high-efficiency hydrocyclone and sent to the online turbidity meter for detection. When the online turbidity meter collects the water quality turbidity display value in real time and it is less than the preset threshold of 5 NTU, the time relay starts timing. After 5 minutes, it enters the next state, that is, the PLC control system controls the first solenoid valve to close and the second solenoid valve to open, so that the water that has undergone secondary treatment in the return pool enters the fire sprinkler pool. Compared with the water in the mine water pool that has undergone secondary treatment, the water in the return pool can significantly shorten the treatment time and improve the treatment efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-3 This utility model provides a technical solution: a high-efficiency hydrocyclone reflux device, including an equalization tank 1, a booster pump 6, a coagulant 8, a high-efficiency hydrocyclone 10, and a fire sprinkler tank 16. The high-efficiency hydrocyclone 10 has a sludge outlet on its bottom side. The equalization tank 1 includes a mine water tank 101 and a reflux tank 102. An inlet pipe 2 is fixedly connected to the mine water tank 101. U-shaped pipes 3 connect the outlets of the mine water tank 101 and the reflux tank 102. A first... A connecting pipe 4 is used to connect the outlet of the booster pump 6 to the inlet of the coagulant 8 via a second connecting pipe 7. The outlet of the coagulant 8 is connected to the inlet of the high-efficiency hydrocyclone 10 via a third connecting pipe 9. The first outlet of the high-efficiency hydrocyclone 10 is connected to the return pool 102 via a return pipe 11. The second outlet of the high-efficiency hydrocyclone 10 is connected to the fire sprinkler pool 16 via an outlet pipe 13. Valve control units for controlling the liquid flow direction are installed on the U-shaped pipe 3, the return pipe 11, and the outlet pipe 13.
[0025] Specifically, such as Figure 3As shown, the valve control unit includes a PLC control system 19, an online turbidity meter 14, a first solenoid valve 12, a second solenoid valve 15, a level sensor 5, a third solenoid valve 17, and a fourth solenoid valve 18. The level sensor 5, the third solenoid valve 17, the fourth solenoid valve 18, the online turbidity meter 14, the first solenoid valve 12, and the second solenoid valve 15 are electrically connected to the PLC control system 19. The PLC control system 19 is used to receive the water turbidity information transmitted by the online turbidity meter 14 and the level information from the level sensor 5, and compare them with a preset threshold. Based on the comparison result, it controls the start and stop of each solenoid valve. The PLC control system 19 is also connected to a display screen, which is used to display the real-time collected water turbidity and level information. The first solenoid valve 12 is located at the inlet of the return pipe 11. The online turbidity meter 14 and the second solenoid valve 15 are respectively located on the upper and lower sides of the connection between the outlet pipe 13 and the return pipe 11. The level sensor 5 is located on the bottom side of the return pool 102. The third solenoid valve 17 and the fourth solenoid valve 18 are respectively installed at the two inlets of the U-shaped pipe 3.
[0026] Working principle: During use, the fourth solenoid valve 18 and the second solenoid valve 15 are opened. Under the action of the booster pump 6, the mine water is treated by the coagulant 8 and the high-efficiency hydrocyclone 10 and then sent to the fire sprinkler pool 16. When the turbidity value of the water exceeds the preset threshold of 5 NTU, the time relay starts timing. After 5 minutes, it enters the next state, that is, the second solenoid valve 15 and the fourth solenoid valve 18 are closed and the first solenoid valve 12 is opened by the PLC control system 19. The water that has undergone initial treatment but does not meet the standards returns to the return pool 102. Under the action of the booster pump 6, the water in the return pool 102 that has undergone initial treatment but does not meet the standards is treated again by the coagulant 8 and the high-efficiency hydrocyclone 10 and sent to the online turbidity meter 14 for detection. When the online turbidity meter 14 collects the water in real time... When the turbidity reading is less than the preset threshold of 5 NTU, the time relay starts timing. After 5 minutes, it enters the next state, where the PLC control system 19 controls the first solenoid valve 12 to close and the second solenoid valve 15 to open, allowing the secondary-treated water in the return pool 102 to enter the fire sprinkler pool 16. The secondary-treated water in the return pool 102 significantly shortens the treatment time and improves the treatment efficiency compared to the water in the mine water pool 101 which is treated again. Then, when the level sensor 5 detects that the level reading is less than the preset threshold, the time relay starts timing. After 5 minutes, it enters the next state, where the PLC system 19 controls the fourth solenoid valve 18 to open and the third solenoid valve 17 to close, treating the water in the mine water pool 101 again, and repeating the above steps.
[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
