[0002] In the field of domestic water use, water treatment processes at water plants are complex and sophisticated, aiming to transform raw water into clean water that meets drinking standards. Potassium permanganate compound salt, as a highly efficient and environmentally friendly oxidant, is widely used in water treatment plants due to its strong oxidizing properties, broad-spectrum bactericidal ability, and effectiveness in removing various pollutants from water. It can effectively remove iron, manganese, organic matter, algae, and odors from water, reduce color, turbidity, and trace heavy metals, and also reduce byproducts generated during disinfection, such as trihalomethanes, thereby improving water safety.

Workers add a fixed weight of potassium permanganate compound salt based on observation of the water level in the tank and experience. However, this method has significant drawbacks: differences in worker experience and judgment lead to inconsistent solution concentrations, affecting water treatment effectiveness and water quality safety; simultaneously, it is impossible to accurately estimate the actual dosage, only a rough estimate can be made, resulting in low efficiency of solution use and difficulty in real-time adjustment according to changes in water quality. Furthermore, the manual preparation and addition process is cumbersome, making real-time control and automated management difficult, increasing the workload of workers, and reducing the efficiency and accuracy of water treatment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4A precision dosing device for potassium permanganate composite salt includes a dosing tank 1. Four dosing inlet pipes 11 are fixedly connected to the front of the dosing tank 1. Each of the four dosing inlet pipes 11 is equipped with a Y-shaped filter 21 and a manual maintenance ball valve 22. The Y-shaped filter 21 filters impurities, and the manual maintenance ball valve 22 allows for timely and convenient maintenance of the dosing inlet pipes 11. A diaphragm pump 12 is fixedly connected to the end of each of the four dosing inlet pipes 11 furthest from the dosing tank 1. Each of the four diaphragm pumps 12 is equipped with... A frequency converter 15 is installed, which can control the frequency of the diaphragm pump 12, making it convenient to control the dosage of potassium permanganate compound salt solution. The drain outlets of the four diaphragm pumps 12 are all fixedly connected to the dosing outlet pipes 13. Each of the four dosing outlet pipes 13 is equipped with an electromagnetic flow meter 14 and a solenoid valve 23. The electromagnetic flow meter 14 can be used to monitor the flow rate of the dosing inlet pipe 11, and the solenoid valve 23 can be used to prevent the solution from flowing out by itself.

[0024] A dissolving tank 2 is fixedly connected to the upper surface of the addition tank 1. A screw feeding mechanism 3 is provided on the right side of the dissolving tank 2. The screw feeding mechanism 3 includes a motor 307 and a weighing sensor 310. A screw feeding rod 308 is fixedly connected to the output end of the motor 307. The screw feeding mechanism 3 also includes a storage bin 301 and a base plate 303. The storage bin 301 is hopper-shaped and can store more than 100 liters of powder.

[0025] The bottom of the storage silo 301 is fixedly connected to a conveying cylinder 304, and the outer surface of the conveying cylinder 304 is fixedly connected to a feeding cylinder 305. The upper surface of the feeding tank 1 is provided with a slot into which the feeding cylinder 305 can extend. The feeding cylinder 305 extends into the slot on the upper surface of the feeding tank 1. After the feeding cylinder 305 extends into it, it does not contact the inner wall of the slot, so as to avoid affecting the weighing of the weighing sensor 310 and causing misjudgment of the accurate addition amount of potassium permanganate composite salt.

[0026] The screw feeding mechanism 3 also includes a support plate 309, a weighing sensor 310 mounted above the support plate 309, a seat plate 303 mounted on the upper surface of the weighing sensor 310, and the seat plate 303 mounted on the weighing bearing plate of the weighing sensor 310, which can weigh objects above the seat plate 303. An extension plate 306 is fixedly connected to the outer surface of the seat plate 303, and a motor 307 is mounted above the extension plate 306. Four support rods 302 are fixedly connected to the upper surface of the seat plate 303, and the tops of the four support rods 302 are fixedly connected to the outer surface of the storage bin 301. Except for the support plate 309 and the weighing sensor 310, the weight of the other components of the screw feeding mechanism 3 is applied to the weighing sensor 310. The weighing sensor 310 can accurately display the reduced mass, that is, the amount of potassium permanganate compound salt added.

[0027] A moisture-proof cover 24 is installed on the upper surface of the storage silo 301. By using the moisture-proof cover 24, the easily damp potassium permanganate composite salt can be effectively prevented from coming into contact with air and becoming damp.

[0028] An external water supply pipe 4 is fixedly connected to the upper surface of the dissolving tank 2. An electromagnetic valve 2 5 and an electromagnetic flow meter 1 6 are installed inside the external water supply pipe 4. By using the electromagnetic valve 2 5 and the electromagnetic flow meter 1 6, the flow rate of the water sent into the dissolving tank 2 can be precisely controlled.

[0029] The inner top wall of the dissolving tank 2 is equipped with a first ultrasonic level gauge 9, and the inner top wall of the addition tank 1 is equipped with a second ultrasonic level gauge 10. By using the first ultrasonic level gauge 9 and the second ultrasonic level gauge 10, the liquid levels inside the addition tank 1 and the dissolving tank 2 can be observed respectively, and the remaining amount of the dissolving liquid can be known in real time, which is convenient for adding more liquid to the tank.

[0030] A first stirrer 7 is installed on the inner top wall of the dissolving tank 2, and a second stirrer 8 is installed on the inner top wall of the addition tank 1. By using the first stirrer 7 and the second stirrer 8, the dissolving liquid inside the addition tank 1 and the dissolving tank 2 can be stirred respectively to avoid precipitation, which would result in different concentrations of the dissolving liquid added to the water treatment tank, thus affecting the water treatment.

[0031] The inner wall of the dissolving tank 2 is fixedly connected to a connecting pipe 18, and the inner top wall of the dosing tank 1 is fixedly connected to a connecting pipe 20. The connecting pipe 18 and the connecting pipe 20 are connected by a solenoid valve 319. By using the solenoid valve 319, the prepared dissolving solution can be extracted from the inside of the dissolving tank 2 and sent into the inside of the dosing tank 1.

[0032] An overflow pipe 16 is installed on the outer surface of the dissolving tank 2, and an overflow pipe 27 is installed on the outer surface of the addition tank 1. By using the overflow pipe 16 and the overflow pipe 27, the dissolving liquid inside the addition tank 1 and the dissolving tank 2 can be drained after abnormal overflow.

[0033] This device is also equipped with a control processor, which controls the motor 307, the weighing sensor 310, the second electromagnetic valve 5, the first electromagnetic flowmeter 6, the first agitator 7, the second agitator 8, the first ultrasonic level gauge 9, the second ultrasonic level gauge 10, the diaphragm pump 12, the second electromagnetic flowmeter 14, the frequency converter 15, the third electromagnetic valve 19, and the first electromagnetic valve 23.

[0034] Working Principle: The controller operates solenoid valve 5 and electromagnetic flowmeter 6, allowing a specified amount of water to be supplied to the dissolving tank 2 via external water pipe 4. Starting motor 307 drives screw feeder 308, precisely adding potassium permanganate composite salt from storage silo 301 into dissolving tank 2 via feed cylinder 305. This initiates solution preparation. After preparation, the controller opens solenoid valve 19, allowing the solution to drain from dissolving tank 2 via connecting pipe 18 and flow into dosing tank 1 via connecting pipe 20 for later use. The remaining solution levels in dosing tank 1 and dissolving tank 2 are monitored in real-time by first ultrasonic level gauge 9 and second ultrasonic level gauge 10, and feedback is sent to the controller. If dissolving tank 2 is found to be empty, solution can be prepared again to prevent mis-mixing. If the remaining solution in dosing tank 1 is insufficient, the controller opens solenoid valve 19 to deliver the solution. The solution can be added into the water treatment tank by starting the diaphragm pump 12. The electromagnetic flow meter 14 transmits flow data to the control processor in real time. The control processor can control the pumping frequency of the diaphragm pump 12 by controlling the frequency converter 15 to achieve precise addition of the solution.
