Common cryogenic insulated cylinder pumped vacuum systems generally comprises the some gas cylinders that are arranged in heating in vacuum room, gas cylinder interlayer is directly connected with vacuum pumping device and carries out vacuum pumping, because gas cylinder band height is little, area is large, the single hole that vacuumizes will be taken out the air in airtight gas cylinder interlayer to the greatest extent, consuming time longer.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of vacuumize efficiency high cryogenic insulated cylinder pumped vacuum systems.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of cryogenic insulated cylinder pumped vacuum systems, comprise the some gas cylinders that are arranged in heating in vacuum room, gas cylinder interlayer is connected with vacuum pumping device, described gas bottle outside lining is provided with air input joint, and air input joint is connected with interlayer heating cabinet, dehumidifier and pressurized air inlet pipe successively by pipeline.
Described in this patent cryogenic insulated cylinder pumped vacuum systems further preferred technological scheme be: being connected with inner bag heating cabinet and blower successively by pipeline from boost port of described cylinder liner.
As the preferred scheme of one, between described gas cylinder interlayer and vacuum pumping device, be provided with cold well.
As the preferred scheme of one, between described gas cylinder, be provided with the pressure pipeline of the each gas cylinder interlayer of UNICOM, pressure pipeline is provided with vacuum measuring instrument.
The beneficial effects of the utility model are: because gas bottle outside lining is provided with air input joint, air input joint is connected with interlayer heating cabinet and pressurized air inlet pipe successively by pipeline, adopt the pressurized air after heating to carry out heat drying to interlayer, remove moisture fast, energy consumption is little, nitrogen replacement is clean, and efficiency is high, can greatly shorten the pumpdown time.
Due to being connected with inner bag heating cabinet and blower successively by pipeline from boost port of described cylinder liner, when interlayer vacuum-pumping, inner bag is heated, make the evaporation of interlayer moisture faster.
