By providing the first liquid level sensor 13 at the bottom of the first suction pipe 12, the control device can obtain the detection data of the first liquid level sensor 13 in real time, and then when the liquid level in the stock liquid barrel 11 drops to a low level, the control device can be informed in time so as to take corresponding measures, such as triggering an alarm signal. In addition, if the batching process is in progress at this time, the system will suspend the batching. After the stock liquid barrel 11 is replaced and the system is reset (for example, by clicking the reset button on the touch screen to reset), the system will continue to perform the batching action.

[0049] Specifically, a check valve (not shown) is provided at the bottom of the first suction pipe 12 to prevent the stock solution from flowing back and causing uneven mixing ratio in the next round.

The second liquid level sensor 23 is connected to the control device by signal, and the control device obtains the detection data of the second liquid level sensor 23 in real time. By providing the second liquid level sensor 23 at the bottom of the second suction pipe 22, the control device can obtain the detection data of the second liquid level sensor 13 in real time, and then when the liquid level in the activator barrel 21 drops to a low level, the control device can be informed in time so as to take corresponding measures, such as triggering an alarm signal. In addition, if the batching process is in progress at this time, the system will suspend the batching, and the system can continue to perform the batching action after the activator barrel 21 is replaced and the system is reset (for example, by clicking the reset button on the touch screen).

[0052] Specifically, a check valve (not shown) is provided at the bottom of the second suction pipe 22 to prevent the activator from flowing back and causing uneven mixing ratio in the next round.

[0053] Specifically, the top of the second suction pipe 22 is connected to the first end of the second hose 24 , and the second end of the second hose 24 is connected to the metering pump P2 disposed at one end of the second pipeline C2 .

[0054] Preferably, the metering pump P1 and the metering pump P2 can be mechanical diaphragm metering pumps made of PVDF. In a specific example, the flow ratio of the metering pump P1 and the metering pump P2 is 10:1. Of course, it can be adjusted accordingly according to different situations.

[0055] Specifically, the first pipeline C1 includes a first main pipeline C11 and a first branch pipeline C12, the outlet of the first main pipeline C11 is connected to the inlet of the first branch pipeline C12 and the inlet of the first side branch pipeline C13, the first main pipeline C11 is provided with a metering pump P1, the first branch pipeline C12 is provided with a first back pressure valve B1 and a valve V03 and is connected to the activation box 3, the first side branch pipeline C13 is provided with a second back pressure valve B2, and the rated pressure of the second back pressure valve B2 is greater than the rated pressure of the first back pressure valve B1. Under normal transportation, since the rated pressure of the second back pressure valve B2 is greater than the rated pressure of the first back pressure valve B1, the raw liquid will be transported to the activation box 3 through the first branch pipeline C12. In the case where the valve V03 is forgotten to be opened, when the pressure provided by the raw liquid in the first side branch pipeline C13 exceeds the rated pressure of the second back pressure valve B2, the second back pressure valve B2 will open, so that the raw liquid can flow out from the first side branch pipeline C13, which can prevent excessive pressure in the pipeline.

[0056] Specifically, the second pipeline C2 includes a second main pipeline C21 and a second branch pipeline C22, the outlet of the second main pipeline C21 is connected to the inlet of the second branch pipeline C22 and the inlet of the second branch pipeline C23, the second main pipeline C21 is provided with a metering pump P2, the second branch pipeline C22 is provided with a third back pressure valve B3 and a valve V01 and is connected to the activation box 3, and the second branch pipeline C23 is provided with a fourth back pressure valve B4, the rated pressure of the fourth back pressure valve B4 is greater than the rated pressure of the third back pressure valve B3. Under normal transportation, since the rated pressure of the fourth back pressure valve B4 is greater than the rated pressure of the third back pressure valve B3, the activator will be transported to the activation box 3 through the second branch pipeline C22. In the case where the valve V01 is forgotten to be opened, when the pressure provided by the activator in the second branch pipeline C23 exceeds the rated pressure of the fourth back pressure valve B4, the fourth back pressure valve B4 will open, so that the activator can flow out from the second branch pipeline C23, which can prevent the pressure in the pipeline from being too high.

[0057] Specifically, the third pipeline C3 includes a third main pipeline C31 and a third branch pipeline C32, the outlet of the third main pipeline C31 is connected to the inlet of the third branch pipeline C32 and the inlet of the third branch pipeline C33, the third main pipeline C31 is provided with a metering pump P3 and a valve V05, the third branch pipeline C32 is provided with a fifth back pressure valve B5 and a valve V07 and connected to the mixing device 4, the third branch pipeline C33 is provided with a sixth back pressure valve B6 and connected to the activation box 3 to return the activated liquid to the activation box 3, and the rated pressure of the sixth back pressure valve B6 is greater than the rated pressure of the fifth back pressure valve B5. Among them, P3 can adopt a mechanical diaphragm metering pump made of PVDF material, and the flow rate is adjustable. Under normal transportation, since the rated pressure of the sixth back-pressure valve B6 is greater than the rated pressure of the fifth back-pressure valve B5, the activated liquid will be transported to the mixing device 4 through the third branch pipe C32. When the valve V07 is forgotten to be opened, when the pressure provided by the liquid in the third branch pipe C33 exceeds the rated pressure of the sixth back-pressure valve B6, the sixth back-pressure valve B6 will open, so that the activated liquid can flow back from the third branch pipe C33 to the activation box 3, thereby preventing excessive pressure in the pipe.

[0058] Specifically, the fourth pipeline C4 includes a fourth main pipeline C41 and a fourth branch pipeline C42, the outlet of the fourth main pipeline C41 is connected to the inlet of the fourth branch pipeline C42 and the inlet of the fourth side pipeline C43, the fourth main pipeline C41 is provided with a metering pump P4 and a valve V06, the fourth branch pipeline C42 is provided with a seventh back pressure valve B7 and is connected to the mixing device 4, the fourth side pipeline C43 is provided with an eighth back pressure valve B8 and is connected to the activation tank 3 to transport reverse osmosis water to the activation tank 3, and the rated pressure of the eighth back pressure valve B8 is greater than the rated pressure of the seventh back pressure valve B7. Under normal transportation, since the rated pressure of the eighth back-pressure valve B8 is greater than the rated pressure of the seventh back-pressure valve B7, the reverse osmosis water will be transported to the mixing device 4 through the fourth branch pipe C42. When the fourth branch pipe C42 is blocked, when the pressure provided by the reverse osmosis water in the fourth branch pipe C43 exceeds the rated pressure of the eighth back-pressure valve B8, the eighth back-pressure valve B8 will open, so that the reverse osmosis water can flow from the fourth branch pipe C43 to the activation box 3, which can prevent excessive pressure in the pipe.

[0059] Preferably, the interior of the mixing device 4 is a bidirectional spiral structure, so that the input materials can be fully mixed.

[0062] Specifically, when the liquid level in the liquid storage tank 5 drops to the first preset liquid level and the liquid level in the activation tank 3 is higher than the second preset liquid level, the control device controls the metering pumps on the third pipeline C3 and the fourth pipeline C4 to work to respectively deliver the activated liquid and the reverse osmosis water to the mixing device 4, and the mixed liquid of the mixing device 4 is delivered to the liquid storage tank 5. At this time, the touch screen 61 can display that the water-liquid mixing is in progress, and can display the current mixed flow delivered to the mixing device 4 in real time.

[0063] When the liquid level in the liquid storage tank 5 rises to the third preset liquid level, the control device controls the metering pumps P3 and P4 on the third pipeline C3 and the fourth pipeline C4 to stop delivering the activated liquid and reverse osmosis water to the mixing device 4. The third preset liquid level is higher than the first preset liquid level. The touch screen 61 can display that the water-liquid mixing is completed.

The touch screen 61 can display that the water-liquid mixing is completed and the batching of the activation tank 3 is in progress. When the system detects that the liquid level of the stock liquid barrel 1 or the activator barrel 2 is insufficient, the system can alarm and suspend the metering. After the stock liquid barrel 1 or the activator barrel 2 is replaced, it can be reset by clicking the touch screen, and the system will continue the batching action that was not completed before the pause.

By first using the first transfer pump P5 to transport a large flow of liquid, and then using the second transfer pump P6 to transport a small flow of liquid based on the disinfectant concentration data detected in real time by the concentration detection device 9, it is beneficial to ensure the infusion speed and ensure that the concentration value of the disinfectant in the disinfection water tank 8 meets the requirements.
