[0002] As an important water treatment agent, PAC (polyaluminium chloride) plays a key role in purifying drinking water, treating industrial wastewater and treating special water quality. However, traditional PAC preparation and dosing methods often rely on manual operation, which leads to inaccurate PAC metering, cumbersome operation and low efficiency. At the same time, due to the manual control of the dosage, it is difficult to meet the requirements of accurate material dosing and system automation.

[0003] In the PAC preparation process, PAC powder is usually added to a tank in a certain proportion, and then added to the required process unit through a metering pump. However, existing PAC preparation devices often lack accurate powder dosing devices, making it difficult to accurately control the dosage. In addition, two tanks are used for preparation and dosing, and the metering unit is more complicated, which not only increases the cost but also affects the preparation efficiency.

[0004] On the other hand, traditional control systems, such as PLC (Programmable Logic Controller), although they achieve automated control to a certain extent, their closed architecture makes it difficult for devices from different suppliers to exchange data on the network, limiting their application in a wider range of scenarios.

[0005] Therefore, in order to solve the above problems, realize the accurate preparation and addition of PAC, and improve the automation and intelligence level of the system, it is particularly important to develop a new type of PAC dosing equipment. This equipment needs to be able to accurately control the dosage of PAC, simplify the operation process, improve the preparation efficiency, and have the ability to exchange data with other equipment to meet the needs of different application scenarios.

[0028] The box assembly 100, as the main structure of the device, can be made of corrosion-resistant materials to ensure that the device can maintain good performance during long-term use. The box assembly 100 has a hollow cavity as a mixing chamber for mixing PAC powder and liquid. In addition to mixing, it can also directly carry the PAC finished solution;

[0029] The liquid adding port assembly 200 is arranged on the top of the box assembly 100, and in practice, the quantitative addition of liquid can be achieved through a precise flow control valve. The user can adjust the amount of liquid added as needed to meet the preparation requirements of PAC solutions of different concentrations;

[0030] The weighing and feeding assembly 300 includes a weighing device 310 disposed on the top of the box assembly 100, a support frame 320 disposed on the weighing device 310, a weighing hopper 330 installed on the support frame 320 and having its lower end passing through the top of the box assembly 100, a feeding baffle 340 rotatably connected to the bottom of the weighing hopper 330, and a feeding motor 350 connected to the feeding baffle 340 via a belt drive. When in use, the feeding motor 350 drives the feeding baffle 340 to rotate along its axis, so that the feeding baffle 340 and the bottom of the weighing hopper 330 can be opened and closed, and the automatic feeding and closed weighing state switching can be realized. The weighing device 310 is combined to accurately measure the weight of the PAC powder, and the feeding baffle 340 and the feeding motor 350 work together to achieve accurate feeding of the PAC powder. This design ensures that the amount of PAC powder added can be accurately controlled, thereby improving the preparation accuracy of the PAC solution;

[0031] The quantitative discharge component 400 is installed at the lower side of the box and communicates with the inner cavity of the box component 100 for quantitative discharge. The component can quantitatively output the prepared PAC solution to the process unit that needs to be processed. The filter 420 is used to prevent impurities from entering the quantitative pump 410 to ensure the stable operation of the equipment;

[0032] The stirring assembly 500 is installed at the bottom of the box assembly 100 and is used for stirring.

[0035] In different embodiments, the stirring assembly 500 includes a stirring motor 510 disposed on the side wall of the box assembly 100 and a stirring roller 520 disposed on the lower side of the inner cavity of the box assembly 100. One end of the stirring roller 520 is connected to the stirring motor 510 through a belt. The stirring roller 520 is connected to the box assembly 100 in a rotational manner. The stirring motor 510 drives the stirring roller 520 to rotate, so that the PAC powder and the liquid are fully mixed to form a uniform PAC solution. This design improves the dissolution efficiency of PAC and ensures the uniformity of the solution.

[0036] In the above embodiment, two stirring rollers 520 are symmetrically arranged, and the two stirring rollers 520 rotate in opposite directions. The two stirring rollers 520 are arranged at the bottom to rotate effectively to prevent the problem of solid particles in the solution sinking to the bottom and affecting mixing.

[0037] In some embodiments, a controller 600 is further provided on the top of the box body, a liquid level meter 110 is provided on the top of the inner cavity of the box body, and the controller 600 is electrically connected to the liquid level meter 110, the weighing and feeding component 300, and the quantitative discharge component 400. The controller 600 can be a controller 600 with a flat display function to automatically adjust the working state of the weighing and feeding component 300 and the quantitative discharge component 400 according to the signal fed back by the liquid level meter 110. The controller 600 also has an intelligent management function, which can adjust the working parameters of the equipment according to actual needs to realize the intelligent operation of the equipment.
