The metering pump 3 is used for conveying the stock solution to the proportioning tank 1, the metering pump 3 is connected with the controller, and the controller controls the flow of the stock solution through the metering pump 3. The proportioning tank 1 is also connected with a water supply pipeline, an electric valve 4 and a flowmeter 5 are arranged in the water supply pipeline, and the electric valve 4 is opened to introduce water into the proportioning tank 1. The flowmeter 5 and the electric valve 4 are also connected with the controller, the flowmeter 5 feeds back water flow to the controller, and the controller controls the opening of the electric valve 4 according to the water flow so as to adjust the ratio of the stock solution to the water. The controller can be connected with a touch screen and the like, an operator can set the concentration of the liquid medicine through the touch screen, and the controller controls the proportion of the water and the stock solution according to the set concentration. The controller can be selected from a industrial control machine, a PLC (programmable logic controller) or a single chip microcomputer and the like, and is not limited herein.
Optionally, a liquid level meter is arranged in the proportioning tank 1 and connected with the controller. In the working process of the dosing system, the liquid level meter can detect the liquid level of the proportioning tank 1 and feed the liquid level back to the controller. When the liquid level of the proportioning tank 1 is too low, the controller controls the metering pump 3 to start, controls the electric valve 4 to open, and conveys stock solution and water into the proportioning tank 1. When the liquid level of the proportioning tank 1 exceeds the preset high liquid level, the controller stops the metering pump 3 and closes the electric valve 4 at the same time. Specifically, the level gauge includes low liquid level floater and high liquid level floater, and low liquid level floater is used for detecting the low liquid level of presetting of ratio jar 1, and high liquid level floater is used for detecting the high liquid level of presetting of ratio jar 1.
