Description

Technical Field

[0001] This utility model belongs to the technical field of mine water treatment equipment, specifically relating to a monitoring device for mine water treatment with controllable feed amount. Background Technology

[0002] During mineral resource extraction, a large amount of mine water is generated. This mine water contains various pollutants such as suspended particulate matter, heavy metal ions, and organic matter. If discharged directly without treatment, it will not only pollute the surrounding soil, water bodies, and other ecological environments, but may also pose a potential threat to human health. Therefore, effective treatment of mine water is an indispensable and crucial step in the mineral resource development process, and its treatment effect is directly related to the implementation of ecological environmental protection and sustainable development strategies. Currently, mine water treatment mainly involves adding various agents to the water to cause pollutants to undergo reactions such as precipitation and flocculation, thereby achieving solid-liquid separation and purifying the water.

[0003] In the reagent mixing process, the existing mixing equipment uses a unidirectional rotating stirring mechanism with a limited stirring range, making it difficult to fully and evenly mix different reagents. This can significantly reduce the reaction effect of the reagents in the water, affecting the removal efficiency of pollutants, and may also cause secondary pollution due to excessively high local reagent concentrations. Therefore, those skilled in the art have provided a monitoring device for mine water treatment with controllable feed amount. Utility Model Content

[0004] The purpose of this invention is to provide a monitoring device for mine water treatment with controllable feed volume in order to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a monitoring device for mine water treatment with controllable feed amount, comprising a mine water treatment tank, a monitoring device, and a mixing tank. The inner wall of the mine water treatment tank is equipped with multiple monitoring sensors, including a turbidity sensor and a pH sensor. The multiple monitoring sensors are electrically connected to the monitoring device. The mixing tank is connected to a dosing nozzle rotatably mounted on the top of the mine water treatment tank via a dosing pipe. The mixing tank includes two stirring rods that are rotatably and slidably connected inside the mixing tank, and the two stirring rods are staggered.

[0006] As a further optimization of this utility model, concave slides are installed on both sides of the top of the inner wall of the mixing box. The two concave slides are symmetrically distributed. A reciprocating screw is rotatably connected to the inside of the two concave slides and located on the inner wall of the mixing box. A slider that is slidably connected to the corresponding concave slide is threaded on the outer wall of the two reciprocating screws. A stirring rod is rotatably connected to the bottom middle position of the two sliders. A transmission gear is fixedly sleeved on the top position of the outer wall of the two stirring rods.

[0007] As a further optimization of this utility model, a toothed plate is fixedly installed between the two transmission gears and on the inner side wall of the mixing box, and the two transmission gears respectively mesh with the two side walls.

[0008] As a further optimization of this utility model, the front side wall of the mixing box is rotatably connected to a synchronous wheel located at the front side position of the corresponding reciprocating screw. The outer side walls of the two synchronous wheels are jointly fitted with a synchronous belt. A first servo motor is fixedly installed on the front side wall of the mixing box, and the output end of the first servo motor is fixedly connected to the front side wall of any synchronous wheel.

[0009] As a further optimization of this utility model, the side wall of the mixing tank is connected with several feeding pipes, the other end of each feeding pipe is connected to a feeding pump, the output end of each feeding pump is connected to a medicine storage tank, and each medicine storage tank is located on the outer side wall of the mixing tank.

[0010] As a further optimization of this utility model, a metering pump is connected through the discharge end of the mixing tank, and a section of the inlet pipe is fixedly connected to the input end of the metering pump.

[0011] As a further optimization of this utility model, an installation plate is fixedly installed on the top of the mine water treatment tank, and a driven gear is rotatably connected to the middle position of the top of the installation plate. The side wall of the driven gear is meshed with a driving gear rotatably connected to the top of the installation plate.

[0012] As a further optimization of this utility model, an L-shaped fixing plate is fixedly installed above the driving gear and at the top of the mounting plate. A second servo motor is fixedly installed at the top of the L-shaped fixing plate. The output end of the second servo motor is fixedly connected to the top of the driving gear. The rotation of the dosing nozzle passes through the bottom of the mounting plate. The driven gear is fixedly sleeved on the outer wall of the dosing nozzle.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, two staggered stirring rods, with the help of reciprocating lead screws, sliders, transmission gears and toothed plates, can simultaneously slide and rotate, and their motion trajectories are staggered, which greatly increases the contact area and stirring range with the medicine, so that different medicines are more fully mixed in the mixing tank, ensuring the stable performance of the medicine.

[0015] 2. In this utility model, the reagent output from the mixing tank is accurately measured by a metering pump, and at the same time, the monitoring device adjusts the feeding amount of the feeding pump in real time according to the monitoring data. This dual guarantee ensures the controllability of the feeding amount, which can not only avoid reagent waste, but also ensure that the water treatment meets the expected standards.

[0016] 3. In this utility model, the dosing nozzle rotates through the transmission of a second servo motor, a drive gear, and a driven gear. Combined with its own spraying function, it can evenly cover all areas of the mine water treatment tank with the agent, thereby improving the reaction efficiency between the agent and the sewage and enhancing the overall water treatment effect.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1 , Figure 2As shown, a monitoring device for mine water treatment with controllable dosage includes a mine water treatment tank 1, a monitoring device 2, and a mixing tank 3. The three work together to form a complete water treatment system. Multiple monitoring sensors are installed on the inner wall of the mine water treatment tank, including turbidity sensors and pH sensors. The multiple monitoring sensors 11 are electrically connected to the monitoring device 2, which can transmit the monitored water quality data, pH value, and turbidity to the monitoring device 2 in a timely manner, providing a basis for dosing decisions. The mixing tank 3 is connected to the dosing nozzle 17 through the dosing pipe 23. The dosing nozzle 17 is rotatably set on the top of the mine water treatment tank 1, which can spray the agent evenly into the treatment tank.

[0026] like Figures 1-4 As shown, the mixing tank 3 is a key component for drug preparation. It contains two stirring rods 8, which are rotatable and slidably connected inside the mixing tank 3 and are staggered. This arrangement enhances the mixing effect. To enable the rotation and sliding of the stirring rods 8, concave slides 4 are installed on both sides of the top of the inner wall of the mixing tank 3. The two concave slides 4 are symmetrically distributed. Reciprocating screws 19 are rotatably connected to the inner walls of the two concave slides 4. Slider blocks 24 are threaded onto the outer walls of the two reciprocating screws 19, and these sliders 24 are slidably connected to the corresponding concave slides 4. Stirring rods 8 are rotatably connected to the bottom center of each of the two sliders 24. Transmission gears 20 are fixedly fitted onto the top of the outer walls of each of the two stirring rods 8. These transmission gears 20 drive the stirring rods 8 to rotate. A toothed plate 7 is fixedly installed between the two transmission gears 20 and on the inner side wall of the mixing tank 3. The two transmission gears 20 mesh with the two side walls of the toothed plate 7 respectively. When the slider 24 drives the transmission gears 20 to move, the transmission gears 20 will rotate under the action of the toothed plate 7, thereby driving the stirring rod 8 to rotate. The front side wall of the mixing tank 3 and the front side position of the corresponding reciprocating screw 19 are rotatably connected to the synchronous wheel 6. The outer side walls of the two synchronous wheels 6 are jointly fitted with the synchronous belt 18. The front side wall of the mixing tank 3 is fixedly installed with the first servo motor 5. The output end of the first servo motor 5 is fixedly connected to the front side wall of any synchronous wheel 6. When the first servo motor 5 is started, the two reciprocating screws 19 will rotate synchronously through the transmission action of the synchronous wheel 6 and the synchronous belt 18, so that the slider 24 slides in the concave slide block 4.

[0027] like Figure 1 , Figure 2As shown, several feeding pipes 9 are connected through the side wall of the mixing tank 3. The other end of each feeding pipe 9 is connected to a feeding pump 21. The output end of each feeding pump 21 is connected to a medicine storage tank 10. The medicine storage tank 10 is located on the outer side wall of the mixing tank 3. The feeding pump 21 can send the medicine in the medicine storage tank 10 into the mixing tank 3 through the feeding pipes 9. The discharge end of the mixing tank 3 is connected through a metering pump 22. One end of the inlet pipe 23 is fixedly connected to the input end of the metering pump 22. The metering pump 22 can accurately control the output amount of the medicine and realize the controllable feeding amount.

[0028] like Figure 1 , Figure 2 , Figure 5 As shown, an installation plate 12 is fixedly installed on the top of the mine water treatment tank 1. A driven gear 13 is rotatably connected to the middle of the top of the installation plate 12. A driving gear 14 meshes with the side wall of the driven gear 13. The driving gear 14 is rotatably connected to the top of the installation plate 12. An L-shaped fixing plate 15 is fixedly installed above the driving gear 14 and on the top of the installation plate 12. A second servo motor 16 is fixedly installed on the top of the L-shaped fixing plate 15. The output end of the second servo motor 16 is fixedly connected to the top of the driving gear 14. The dosing nozzle 17 rotates through the bottom of the installation plate 12, and the driven gear 13 is fixedly sleeved on the outer side wall of the dosing nozzle 17. When the second servo motor 16 is started, the driving gear 14 can be driven to rotate. The driving gear 14 drives the driven gear 13 to rotate, thereby causing the dosing nozzle 17 to rotate and expanding the dosing range.

[0029] In this scheme, the first servo motor 5 and the second servo motor 16 can be servo motors with explosion-proof function, such as the mining explosion-proof DC servo motor with model number 60ST-M01330B-EX-24V-MA, which is suitable for dust explosion-proof and gas explosion-proof environments, with a rated speed of up to 3000rpm and a rated power of 400W, which can meet the requirements of motor power and safety performance in mine water treatment devices. The metering pump 22 can be a GM type precision metering pump, taking into account the low-pressure scenario requirements of mine water treatment and the requirements for flow control accuracy. The feed pump 21 can be an IH type single-stage single-suction cantilever centrifugal pump. The turbidity sensor in the monitoring sensor 11 adopts the Aztec ATS430 turbidity and total suspended particulate sensor, and the pH sensor adopts the Babel BT6108-pH series pH water quality automatic analyzer.

[0030] It should be noted that when the monitoring device for mine water treatment with controllable feed rate is working, the monitoring sensor 11 monitors the water quality in the mine water treatment tank 1 in real time. The monitoring device 2 controls the feeding pump 21 to draw the corresponding agent from the agent storage tank 10 according to the monitoring data and sends it into the mixing tank 3 through the feeding pipe 9. The first servo motor 5 starts and drives the two reciprocating screws 19 to rotate through the synchronous wheel 6 and the synchronous belt 18, so that the slider 24 slides in the concave slide seat 4. The slider 24 drives the transmission gear 20 to move. The transmission gear 20 rotates under the action of the toothed plate 7, so that the stirring rod 8 slides and rotates at the same time to fully mix the agent in the mixing tank 3. The mixed agent is delivered to the dosing nozzle 17 through the metering pump 22 and the inlet pipe 23. The second servo motor 16 drives the dosing nozzle 17 to rotate, so that the agent is evenly sprayed into the mine water treatment tank 1, realizing mine water treatment with controllable feed rate.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
