The output port of the diaphragm pump A2 is connected to the weighing barrel 15 through a pipeline. The detection end of the liquid level meter B11 and the stirring end of the mixer B13 are both vertically installed inside the proportioning barrel 12; preferably, the mixer B13 is located at the center of the proportioning barrel 12. The operator determines whether to add stock liquid to the proportioning barrel 12 based on the real-time displayed liquid level value of the liquid level meter B11. If replenishment is required, turn on the diaphragm pump A2 and pump the stock liquid in the stock liquid barrel 1 to the weighing barrel 15. The mixer B13 is used to preliminarily mix the stock liquid and tap water to ensure the uniformity of the mixed liquid in the proportioning barrel 12.

[0030] There are multiple solenoid valves, namely solenoid valve A51, solenoid valve C14, solenoid valve D16 and solenoid valve E17.

[0031] The solenoid valve D16 and the solenoid valve E17 are installed on the top of the support frame B20;

[0033] The solenoid valve A51 is located in the connecting pipe between the output port of the diaphragm pump A2 and the solenoid valve E17, and is used to prevent the raw liquid in the pipe from flowing back into the raw liquid barrel 1, ensuring that the pipe is always full of raw liquid and reducing the error in raw liquid transportation.

[0034] The solenoid valve C14 is located in the communication pipeline between the weighing barrel 15 and the proportioning barrel 12 , and is used to control the volume of the liquid principle entering the proportioning barrel 12 .

[0036] Specifically, the specific steps of the proportioning module are:

[0037] (1) When the liquid level meter 11 shows that the liquid level in the proportioning barrel 12 is low, the solenoid valve A51 and the solenoid valve E17 are opened in sequence, and the solenoid valve C14 is closed; at this time, the diaphragm pump A2 draws raw liquid from the raw liquid barrel into the weighing barrel 15. When the electronic scale 18 shows that the raw liquid in the weighing barrel 15 reaches the set weight, the solenoid valve E17 and the solenoid valve A51 are closed in sequence; in this embodiment, the set raw liquid weight is 5 kg.

[0038] (2) Keep solenoid valve A51 and solenoid valve E17 closed, solenoid valve C14 open, and the weighed stock solution flows into the proportioning barrel 12 under the action of gravity; after completion, close the solenoid valve C14.

[0039] (3) Keep the solenoid valves A51, E17 and C14 closed, open the solenoid valve D16, and allow the tap water in the water storage tank to enter the weighing bucket 15; when the electronic scale 18 shows that the newly added tap water in the weighing bucket 15 has reached the set weight, close the solenoid valve D16; in this embodiment, the stock solution and tap water are mixed in a ratio of 1:3, so the set tap water weight is 15 kg.

[0040] (4) Keep the solenoid valve D16 closed and the solenoid valve C14 open, and the weighed tap water flows into the proportioning barrel 12 under the action of gravity; after completion, close the solenoid valve C14.

[0045] The liquid level meter A8 and the stirrer A10 are vertically installed inside the mixing barrel 9, and the stirrer A10 is located at the center to ensure that the mixed liquid is fully stirred and homogenized.

[0046] Specifically, the mixing module works in such a way that when the liquid level meter A8 in the mixing barrel 9 detects a low liquid level, the diaphragm pump C4 is started, and then the solenoid valve B61 is opened, and the mixed liquid with a good proportion in the weighing barrel 15 is pumped into the mixing barrel 9 .

[0047] Preferably, the volume of the mixed liquid extracted by the diaphragm pump C4 from the proportioning barrel 12 at a single time is 5L.

[0049] The moving module comprises a pulley 21 .

[0050] The pulleys 21 have a self-locking function, and there are four of them, which are installed at the four corners of the lower part of the support frame A19, so that the entire mixing and moving module device can be easily moved between different positions. The self-locking function ensures that the device can stay stably at the specified position when needed.

[0051] As the basic supporting structure of the entire module, the support frame A19 needs to ensure the stable installation of various components. The support frame A19 is made of stainless steel, which is corrosion-resistant and not easy to rust.
