Description

Technical Field

[0001] The present invention belongs to the technical field of conveying, and particularly relates to a blanking device, and more particularly to a liquid blanking device and a blanking method thereof. Background Art

[0002] During the blanking process of liquid, the liquid flows through a flowmeter and then flows downward from the lower end of the blanking pipe to a container, and the volume of the liquid flowing into the container is calculated according to the flow rate displayed by the flowmeter.

[0003] However, for a traditional blanking pipe, it is unpredictable how much liquid is stored in the blanking pipe before blanking starts. Therefore, there will be errors when the flowmeter measures the volume of the blanking liquid.

[0004] When a traditional blanking pipe conveys liquid into a container, the liquid impacts the bottom wall or side wall of the container under the action of pressure and its own gravity; if the conveyed liquid has certain corrosiveness, the liquid with impact directly impacts the bottom wall or side wall of the container, which will affect the service life of the container.

[0005] Therefore, how to avoid the direct impact of the bottom wall or side wall of the container when the blanking pipe blanks is a technical problem that needs to be solved urgently in this field.
