Description

Technical Field

[0001] The invention relates to a pipeline proportional liquid aspirating device, which is used for adding a small amount of functional liquid into a large fluid. Background Art

[0002] In industrial and agricultural production, it is often necessary to add a small amount of liquid to a large flow of liquid or gas, such as fertilizing and applying pesticides while irrigating fields. Some methods use the negative pressure generated by the jet to absorb the liquid, some are injected through a driving device, and some are slowly dripped into the flowing liquid. The suction volume of the ordinary jet method is greatly affected by the jet speed. Since the amount of liquid added in the drive injection method and the dripping method has no correlation with the fluid, it is necessary to collect the flow data of the large fluid in order to add it in proportion. These methods are either difficult to accurately control the proportional relationship between the added liquid and the main fluid, resulting in large fluctuations in the concentration of the mixture, or require a complex control system to achieve. For example, when fertilizing in proportion during farmland irrigation, a movable proportional fertilization device disclosed in patent CN201820015057.2 requires electronic control and mechanical actuators. Patent CN201510771913.8 discloses a hydraulically driven fixed-proportion fertilizer pump that does not require electronic control and drive, but has a complex structure and high cost.
