Problems solved by technology

Gases from both sources above eventually lead to bulging of the container
[0004]Because the container bulge exceeds the pressure that the container wall or container cover can withstand, it will cause the container cover to loosen or even the container wall to rupture, which will cause the liquid to overflow, causing economic loss
If the liquid is toxic or corrosive, it will also cause major accidents, so it is necessary to solve the above-mentioned container swelling problem

Abstract

The invention relates to the field of filling equipment, and provides a filling method and a system. The method comprises the following steps that S1, a container is filled with a liquid; S2, externalforce is applied to deform the container, and the deformation state of the container is kept; S3, the container is sealed; and S4, the external force is released to enable the container to recover tothe original state. The method has the advantages that gas in the container is exhausted in advance, the sealed container is prevented from bulging, and the risk of tank explosion is reduced.

Description

technical field [0001] The invention relates to the field of filling equipment, in particular to a filling method and system. Background technique [0002] Liquid products need to be filled into suitable containers for transportation and storage. However, during the storage and transportation process after the product is filled, there must be changes in temperature or air pressure, so the gas volume in the container will change. If the volume of the gas expands, it will cause the container to bulge and deform; if the gas continues to expand excessively, it may cause a "explosion tank". [0003] There are two reasons that cause the container to bulge so that it "explodes the tank". On the one hand, the liquid product does not occupy all the space in the container, so there is gas in the container (it may be air, or other gases artificially filled); on the other hand, during the filling process, due to the ambient temperature and Affected by factors such as pumping flow rat...
