Abstract
The utility model discloses a sealed box body for separated quantification of specific gas content, which realizes gas control of a glove box and meets the requirements of experiment and production. The sealed box body comprises a sealed box body and a quantification device of specific gas content, wherein the quantification device of the specific gas is connected with the sealed box body by a pipe.
Description
Technical field
The utility model relates to a kind of closed box, but relates in particular to a kind of closed box of isolated operation of quantitative setting specific gas content.
Background technology
Traditional glove box or drying box mainly provide the casing of a sealing, and the pressure in the casing can be regulated automatically, and operating personnel can enter in the casing by the gloves of sealing and operate.
At present, main flow glove box both domestic and external is integrated dewatering and the device of deoxygenation in system, is used to provide operating environment (water＜1ppm, the O of anhydrous and oxygen-free
2＜1ppm).Casing is by an EGR, with the gas in the casing through dewatering and deaerating plant constantly purifies, thereby reach the environment of anhydrous and oxygen-free, tank pressure remains in the scope of setting.
Along with science and technology development, the use occasion that requires to increase atmosphere control on the basis of above-mentioned glove box gets more and more, and simple inert atmosphere glove box can not satisfy diversified experiment and production requirement.
At above-mentioned technical problem, the utility model proposes a kind of new technical scheme.
The utility model content
But technical problem to be solved in the utility model provides a kind of closed box of isolated operation of quantitative setting specific gas content, has realized the control of atmosphere in the case, has satisfied experiment and production demand.
In order to solve above technical problem, the utility model provides following technical scheme:
But the utility model provides a kind of closed box of isolated operation of quantitative setting specific gas content, comprises a closed box, also comprises the quantitative setting device of a specific gas content, is connected by pipeline with closed box.
In addition, the quantitative setting device of described specific gas content can comprise the quantitative distribution unit of detecting unit, PLC control module and the specific gas of specific gas.
But the closed box of the isolated operation of the quantitative setting specific gas content that the utility model adopts, the PLC control module is accepted the also signal of analyzing and testing unit, send the distribution instruction to the distribution unit in view of the above, thereby realized the setting requirement of specific gas content in the glove box, satisfied experiment and production demand.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The specific embodiment
Please refer to Fig. 1, it is the schematic diagram of glove box in the prior art.Glove box comprises casing 100, can also comprise de-watering apparatus 120, deaerating plant 130 etc., connects by pipeline 110 between these devices.The glove box of prior art can be realized dewatering, deoxygenation is less than 1ppm, but can't control the concentration of specific gas, so can not satisfy the demand of current test and production.
Please refer to Fig. 2, it is a schematic diagram of the present utility model.Closed box of the present utility model also comprises the quantitative setting device of a specific gas content except comprising casing 200, be connected by pipeline with casing 200.Wherein, the quantitative setting device of specific gas content may further include detecting unit 210, PLC control module 220, distribution unit 230.Wherein, the quantitative setting of specific gas content is achieved in that detecting unit 210 is connected with casing 200, detect the content of specific gas in the casing 200, then send the testing result signal to PLC control module 220, it need to judge whether distribution, and as the needs distribution, PLC control module 220 sends the distribution instruction to distribution unit 230, the distribution unit 230 quantitative specific gas of providing and delivering in casing 200 meets the setting requirement up to the specific gas content that detects.
Please refer to Fig. 3, it is the schematic diagram of quantitative distribution unit among the utility model one embodiment.In the present embodiment, the inert gas in the casing 300 is an argon gas, and specific gas is a carbon dioxide.Argon gas is gone into casing 300 through little mist separator 341, the band Pressure gauge 331 of pressure switch and mass flowmenter 322 are laggard successively, and carbon dioxide is gone into casing 300 through the Pressure gauge 330 of little mist separator, band pressure switch and mass flowmenter 321 are laggard successively.
The above be preferred embodiment of the present utility model only, be not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
Claims (2)
1. but a closed box of quantitatively setting the isolated operation of specific gas content comprises a closed box, it is characterized in that, also comprises the quantitative setting device of a specific gas content, is connected by pipeline with closed box.
2. closed box as claimed in claim 1 is characterized in that, the quantitative setting device of this specific gas content is made up of the quantitative distribution unit of detecting unit, PLC control module and the specific gas of specific gas content.
