Embodiment 1

[0028] Such as figure 1 The shown liquid filling and inert gas filling and protection integrated device includes a submersible liquid and gas integrated filling head, upper seal 4, lower seal 5, inert gas control valve 9, vacuum control valve 8, vacuum pump 10, inert gas The container 11, the vertical lifting device and the controller 7; the submerged liquid gas integrated filling head includes the submerged liquid filling head 2 and the submerged gas filling head 6 fixedly connected side by side, and the submerged liquid filling head The liquid outlet of 2 is lower than the gas outlet of submersible gas filling head 6;

[0029] The submersible liquid filling head 2 communicates with the liquid to be filled through the liquid pipeline 12, and the submersible liquid filling head 2 is provided with a liquid control valve 1; the submersible gas filling head 6 communicates with the gas pipeline 13 , the gas pipeline 13 divides into the first gas branch 14 connected with the inert...

Embodiment 2

[0037] Such as figure 2 The shown liquid filling and inert gas filling and protection integrated device differs from Embodiment 1 in that the middle part of the lower sealing member 5 has a cross-shaped opening; and the lower sealing member 5 is plugged into the opening of the container to be filled, and the lower sealing member 5 The upper end is flush with the opening of the filling container.

Embodiment 3

[0039] The integrated device for liquid filling and inert gas filling and protection differs from Embodiment 1 in that the inert gas control valve 9 and the vacuum control valve 8 are replaced by a three-way valve, and the three-way valve is electrically connected to the controller 7; One end of the through valve communicates with the gas pipeline 13 , and the other two ends are respectively connected with the first gas branch 14 and the second gas branch 15 .

Abstract

The invention relates to a liquid filling and inert gas filling protection integrated device. The device comprises a dived liquid-gas integrated filling head, an upper sealing piece, a lower sealing piece, an inert gas control valve, a vacuum control valve, a vacuum pump, an inert gas container, a vertical lifting device and a controller; and the dived liquid-gas integrated filling head includes a dived liquid filling head and a dived gas filling head fixedly connected side by side. The invention further discloses a method for liquid filling and inert gas filling protection integrated filling by using the liquid filling and inert gas filling protection integrated device. The liquid filling and inert gas filling protection integrated device realizes the liquid filling and inert gas filling equipment integration, overcomes the defect of halfway protection of filled liquid and inert gas caused by the filled liquid still having oxygen due to operation equipment bottle transportation and separate operation in a traditional liquid filling and nitrogen filling separate operation method, and largely reduces the equipment cost.

Description

technical field [0001] The invention relates to the technical field of liquid filling, in particular to an integrated device for liquid filling and inert gas filling and protection and a filling method thereof. Background technique [0002] Liquid filling is widely used in daily chemical, oil and other industries, and can fill different high-viscosity fluids. Filling refers to the operation of filling a specific required liquid or semi-fluid into a designated container. There are many factors that affect liquid filling, such as viscosity, foaming and tiny impurity content. At present, there are mainly the following methods for liquid filling: 1. Atmospheric pressure filling. Under normal pressure conditions, it mainly depends on the self-weight of the liquid being filled to flow into the designated container. The device and the method are suitable for filling common liquids without special requirements. 2. Vacuum and filling. Filling of specified liquids at subatmospher...
