Pull-plug type breathing device of closed container

Abstract

The invention relates to a pull-plug type breathing device of a closed container, comprising a shell box and a combined type integral anti-pollution filtering plug-in unit, wherein the combined type integral anti-pollution filtering plug-in unit is arranged in the shell box. The pull-plug type breathing device has the advantages of simple structure, low cost and safety and convenience for use, can not only be used for the technical improvement of the pollution and volatilization prevention of the rational open-type container, but also be merged into the newly produced closed container. The pull-plug type anti-pollution filtering breathing device has the advantages of unit modular design of an assembly, plant standardized production, safety in operation, convenience for maintenance and fast installation.

Description

technical field [0001] The invention relates to a breathing device acting on the dynamic volume change balance of the liquid-gas two-phase in a closed container, in particular to a plug-in breathing device for a closed container. Background technique [0002] At present, in the known open container for entering and exiting liquid, the gas in the space above the container communicates with the atmosphere. As the liquid enters and exits below the container and the level of the liquid changes up and down, the liquid can flow in and out freely through the container. But precisely because of the open type, the liquid in the container is easily polluted by the outside atmosphere and affects the quality of the liquid; at the same time, the beneficial gas agent in the liquid is also easily volatilized, and the polluted gas outside enters, which affects and reduces the quality of the liquid. And the quantity, after a long time, the liquid is prone to bacteria, viruses and pollution, ...

Problems solved by technology

But precisely because of the open type, the liquid in the container is easily polluted by the outside atmosphere and affects the quality of the liquid; at the same time, the beneficial gas agent in the liquid is also easily volatilized, and the polluted gas outside enters, which affects and reduces the quality of the liquid. And quantity, after a long time, the liquid is prone to bacteria, viruses and pollution, and the container needs to be cleaned and maintained, causing a lot of waste

[0003] However, if the container is airtight, the gas above the container is separated from the outside atmosphere. Although the liquid below the container will not be polluted and volatilized, the liquid below the container cannot enter or exit, so the container is useless.
