Technical Field

Background

In industrial and agricultural production, it is often necessary to add a small amount of liquid to a large flow of liquid or gas, for example, to fertilize and apply pesticide while irrigating a field, to suck liquid by using negative pressure generated by a jet flow, to inject the liquid by a driving device, or to gradually drop the liquid into a flowing liquid. The common jet flow mode has a large influence on the suction volume due to the jet flow speed, and the injection driving mode and the dropping driving mode need to acquire the flow data of large fluid for proportional addition because the addition amount of liquid has no correlation with the fluid, and the modes either have difficulty in accurately controlling the proportional relation between the added liquid and the main fluid to cause large fluctuation of the mixture concentration or need a complex control system to realize the control. For example, in the case of proportional fertilization in farmland irrigation, the movable proportional fertilization device disclosed in patent CN201820015057.2 requires an electric control and mechanical actuator. The patent CN201510771913.8 discloses a hydraulic drive's ration fertilization pump, does not need automatically controlled and drive, but the structure is complicated, and the cost is high.
