Abstract
A gas cylinder group vacuum drier mainly comprises an evacuating device, a valve, a vacuum pressure meter, a gas tube, a drying tube, a gas cylinder clamp, a gas cylinder interface, a corrugate tube, a gas fill valve and an emptying valve, wherein the valves are mounted between the evacuating device and the gas tube. The gas cylinder group vacuum drier is characterized in that the evacuating device is a root evacuating unit. The utility model has the advantages that the gas cylinder group vacuum drier can improve exhaustion efficiency, reduce vacuum degree and improve accuracy.
Description
Technical field
The present invention relates to a kind of gas apparatus, especially a kind of gas cylinder group Minton dryer.
Background technology
Its final vacuum of gas cylinder group Minton dryer commonly used is generally 5～10 * 10
-2Pa, its structure is formed and is generally included vavuum pump, stop valve, pressure vacuum gauge, tracheae, drying box, gas cylinder anchor clamps, bellows, fills out air valve and atmospheric valve, just mentions above-mentioned gas cylinder group Minton dryer in " high-purity gas cylinder drying vacuumizes optimum manipulation method " literary composition of delivering on the second phase in 1993 " cryogenics " as Zhou Wenguo.Yet the above-mentioned device speed of exhaust is low, and accuracy is poor, and vacuum can not satisfy the demand of existing high-purity gas cylinder.
Summary of the invention
At above-mentioned existing problems, the invention provides a kind of gas cylinder group Minton dryer, by the change of structure, can
In order to reach above purpose, the present invention takes following technical scheme, a kind of gas cylinder group Minton dryer, mainly comprise vacuum extractor, valve, pressure vacuum gauge, tracheae, drying box, gas cylinder anchor clamps, cylinder interface, bellows, fill out air valve and atmospheric valve, valve is installed between vacuum extractor and the tracheae, it is characterized in that: described vacuum means is changed to Roots's vacuum unit.
The present invention has the following advantages: improved pumping efficiency greatly, reduced vacuum simultaneously, improved accuracy.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention
1, Roots's vacuum unit 2, vacuum butterfly valve 3, tracheae 4, exhaust-valve 5, fill out air valve 6, cylinder interface 7, gas cylinder anchor clamps 8, bellows 9, drying box 10, thermocouple vacuscope 11, vacuum gauge 12, pressure vacuum gauge 13, pressure gauge valve 14, closed box
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment one
As shown in Figure 1, a kind of gas cylinder group Minton dryer of the present invention, mainly comprise vacuum extractor (using the Roots's vacuum unit 1 that is in this patent), valve (what use in this patent is vacuum butterfly valve 2), pressure vacuum gauge 12, tracheae 3, drying box 9, cylinder interface 6, gas cylinder anchor clamps 7, bellows 8, fill out air valve 5 and atmospheric valve 4, Roots's vacuum unit 1 is connected by vacuum butterfly valve 2 with tracheae, pressure vacuum gauge 12, fill out air valve 5 and atmospheric valve 4 and be connected nearly vacuum butterfly valve 2 ends of tracheae by pipeline, tracheae 3 is by cylinder interface 6, bellows 8, gas cylinder anchor clamps 7 are connected with treating the vacuum drying gas cylinder, treat the vacuum drying gas cylinder is placed in the drying box 9 (have usually how group is treated the vacuum drying gas cylinder, corresponding drying box just has a plurality of), for safety, drying box 9 can be placed in the closed box 14 usually.
Embodiment two
With a kind of gas cylinder group Minton dryer of embodiment one, its difference is: described tracheae 3 nearly cylinder interface ends are equipped with a thermocouple vacuscope 10, and thermocouple vacuscope 10 is connected with tracheae by vacuum gauge 11.Because the precision of thermocouple vacuscope 10 reaches 0.1Pa, so can more accurate control vacuum.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
