Abstract

The invention discloses a vacuumization air exhausting device. The vacuumization air exhausting device comprises a high-vacuum multi-layer heat insulating container, a rough vacuumizing unit, a fine vacuumizing unit, an electric control system and a heating device. The rough vacuumizing unit is connected with the fine vacuumizing unit through a pipeline. The fine vacuumizing unit is communicated with the high-vacuum multi-layer heat insulating container through a main pipeline. The high-vacuum multi-layer heat insulating container is connected with the heating device through a pipeline. The rough vacuumizing unit, the fine vacuumizing unit and the heating device are connected to the ectric control system. The vacuumization air exhausting device is scientific and reasonable in structural design, easy and convenient to operate and capable of effectively removing moisture in a vacuum interlayer and effectively reducing the energy resource consumption.

Description

Technical field [0001] The invention relates to a vacuuming system, in particular to a vacuuming and exhausting device which can effectively remove water vapor in the vacuum interlayer of a high-vacuum multilayer heat-insulating container. Background technique [0002] At present, the commonly used vacuum exhaust system is composed of a vacuum pump and other equipment (such as measuring instruments, vacuum pipes, vacuum valves, etc.) to obtain a high vacuum device. [0003] The high-vacuum multilayer heat-insulating container adopts the high-vacuum multilayer heat-insulating method, which is a structure in which a composite heat-insulating layer of aluminum foil and glass fiber paper is wound into the container in the bottle, and at the same time, the sandwich is subjected to high-vacuum treatment. There are several difficulties in obtaining high vacuum: [0004] 1. The interlayer leakage rate is too high, the adsorbent efficiency is low, and the high vacuum maintenance time is not ...
