【Technical field】

The utility model relates to a liquid proportioning system, in particular to a liquid proportioning control system for automatically controlling the proportioning concentration.

【Background technique】

When water-soluble liquids are mixed with water, the proportioning concentration is generally controlled by manual operation. Manually controlling the proportioning concentration not only wastes human resources, but also causes different proportioning concentrations due to operational errors and other reasons, which affects production efficiency. In the process of treating industrial waste gas, adding biological enzymes to pure water can effectively eliminate odors and organic substances in the air. However, due to the relatively high cost of biological enzymes, if the concentration is too high, the cost of waste gas treatment will increase. , but if the proportioning concentration is too low, it will affect the effect of waste gas treatment and fail to meet the emission standards. Therefore, it is necessary to provide a liquid proportioning control system for automatically controlling the proportioning concentration.

【Description of drawings】

Fig. 1 is a schematic diagram of the connection structure of the present invention.

【detailed description】

The following examples are further explanations and supplements to the utility model, and do not constitute any limitation to the utility model.

Example 1

As shown in Figure 1, a kind of liquid automatic proportioning control system of the present embodiment comprises pure water tank 10, raw liquid tank 20 and liquid distribution tank 30, and described pure water tank 10 is connected with liquid distribution tank 30 by circulation pump 40 The raw solution tank 20 is connected to the liquid distribution tank 30 through a metering pump 50 . Pure water is contained in the pure water tank 10, and biological enzymes are contained in the stock solution tank 20, which can be dissolved in pure water. When proportioning, the circulating pump 40 pumps the pure water in the pure water tank 10 into the liquid distribution tank 30 In the process, wait for all the pure water in the pure water tank 10 to be pumped, and then start the metering pump 50 to pump the biological enzyme into the liquid distribution tank 30. The biological enzyme pumped by the metering pump 50 is accurately metered each time. Since the amount of water has been fixed by the pure water tank 10, it is necessary to increase the concentration of biological enzymes in the liquid distribution tank 30, and it is only necessary to increase the amount pumped by the metering pump 50 to achieve the purpose of automatic proportioning.

Example 2

As shown in Figure 1, in order to ensure that the amount of pure water pumped into the liquid distribution tank 30 by the circulation pump 40 is fixed each time, the present embodiment adds a high water level detection device 11 and a low water level detection device 12, the pure water tank 10 A high water level detection device 11 is arranged on the top of the interior, and a low water level detection device 12 is arranged on the bottom of the pure water tank 10. The water level difference between the high water level detection device 11 and the low water level detection device 12 is a fixed value. 10 is connected to the water storage tank 70 through a water pump, and the high water level detection device 11 and the low water level detection device 12 detect and feed back signals to control the stop and start of the water pump. First of all, the circulation pump 40 must ensure that there is water in the pure water tank 10 every time it pumps pure water into the liquid distribution tank 30, and it will stop working when the water storage level in the pure water tank 10 is equal to the low water level detection device 12 each time. , then the water storage tank 70 supplies water to the pure water tank 10, and when the water in the pure water tank 10 reaches the high water level detection device 11, the water supply to the pure water tank 10 is stopped, so as to ensure that the liquid is pumped into the pure water tank 10 each time The volume of water in tank 30 is equal. The water pump just starts when the water storage level in the pure water tank 10 is equal to the low water level detection device 12 at every turn, and pumps water in the pure water tank 10 .

Example 3

As shown in Figure 1, in order to ensure that the biological enzymes in the original solution tank 20 are always in a supplyable state, a high liquid level detection device 21 is arranged above the inside of the original solution tank 20 in this embodiment, and a low liquid level detection device is provided under the inside of the original solution tank 20. The detection device 22, the high liquid level detection device 21 and the low liquid level detection device 22 are both connected with a buzzer. If the biological enzyme in the original solution tank 20 reaches the high liquid level detection device 21, then the buzzer reports to the police, prompting does not need to add biological enzyme in the original solution tank 20, if the biological enzyme in the original solution tank 20 reaches the low liquid level detection device 22, Then the buzzer will give an alarm, indicating that the biological enzyme needs to be added. Ensuring that biological enzymes are always available.
