Abstract
The invention relates to a glove box, in particular to a nitrogen-removing glove box system. The nitrogen-removing glove box system comprises a glove box body, a circulating pipeline connected to the glove box body, a circulating fan and a purifying system. The circulating fan and the purifying system are arranged on the circulating pipeline. The nitrogen-removing glove box system is characterized in that a nitrogen absorption device is arranged on the circulating pipeline, and a titanium sponge and a heating device are arranged in the nitrogen absorption device. The nitrogen-removing glove box system is particularly suitable for the field of production of lithium batteries, can effectively remove nitrogen leaving in the glove box body and residual nitrogen caused by opening of a large bin and a small bin and avoids the phenomenon that the nitrogen can react with lithium metal to generate lithium nitride, and the quality of the battery is seriously affected.
Description
Technical field
The present invention relates to glove box, particularly a kind of glove box system except nitrogen.
Background technology
Produce in the process of lithium battery using glove box, because lithium is active metal, pole, can react with many materials, the species adsorbs such as the water oxygen in tracheae can fall by the cleaning system of glove box system, but the nitrogen of remnants can be cumulative along with the service time of glove box when the nitrogen be retained in gloves casing and size storehouse are opened, these nitrogen can react with lithium metal, generate lithium nitride, have a strong impact on the quality of battery.
Summary of the invention
The object of the present invention is to provide a kind of glove box system except nitrogen, mainly solve the defect existing for above-mentioned prior art, it is specially adapted to lithium battery production field, effectively can remove the nitrogen being retained in remnants when nitrogen in gloves casing and size storehouse are opened, avoid these nitrogen can react with lithium metal, generate lithium nitride, have a strong impact on the quality of battery.
For achieving the above object, the present invention realizes like this.
Except the glove box system of nitrogen, it comprises gloves casing, be connected to the circulation line on gloves casing and the circulating fan be arranged on circulation line and cleaning system; It is characterized in that: this circulation line is also provided with and inhales nitrogen device, this suction nitrogen device is built with titanium sponge and with heater.
The described glove box system except nitrogen, it is characterized in that: this circulation line installs bypass additional, this bypass is arranged and inhales nitrogen device, the bypass at these suction nitrogen device two ends is connected with circulation line by two bypass valves, and the circulation line between this bypass is also equipped with a valve.
Above structure, the present invention has technique effect superior as follows.
1, when the present invention uses, it is inhaled nitrogen device and titanium sponge is housed and with heater, and the nitrogen in gas to react generation titanium nitride with titanium sponge, and through circulation after a while, the nitrogen in atmosphere can gradually reduce, and reaches desired value.
2, the present invention effectively can remove the nitrogen being retained in remnants when nitrogen in gloves casing and size storehouse are opened, and avoids these nitrogen can react with lithium metal, generates lithium nitride, have a strong impact on the quality of battery.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of the present invention.
In figure: 1-gloves casing; 2-circulation line; 3-circulating fan; 4-inhales nitrogen device; 5-cleaning system; 6-bypass valve; 7-valve; 9-bypass.
Detailed description of the invention
Refer to Fig. 1, it is a kind of structural representation of glove box system compared with embodiment removing nitrogen of the present invention.As shown in the figure: it comprises gloves casing 1, be connected to the circulation line 2 on gloves casing 1 and the circulating fan 3 be arranged on circulation line 2 and cleaning system 5; This circulation line 2 is also provided with and inhales nitrogen device 4, this suction nitrogen device 4 is built with titanium sponge and with heater.This circulation line 2 installs bypass 9 additional, and this bypass 9 is arranged and inhales nitrogen device 4, the bypass 9 at these suction nitrogen device 4 two ends is connected with circulation line 2 by two bypass valves 6, the circulation line 2 between this bypass 9 is also equipped with a valve 7.
During use, can enable bypass 9 arranges inhale nitrogen device 4 by opening two bypass valves 6, inhale nitrogen device and titanium sponge is housed and with heater, nitrogen in gas to react generation titanium nitride with titanium sponge, through circulation after a while, nitrogen in atmosphere can gradually reduce, and reaches desired value.
At glove box after running after a while, constantly a small amount of residual nitrogen also constantly can be brought into glove box and remain by open size storehouse, accumulates over a long period, also can form finite concentration.Also to carry out in the case above-mentionedly denitrogenating program.Glove box opens a position after overhaul, also will carry out similar operation.
As the simplest embodiment of one of the present invention, nitrogen removing device can be contained on major cycle pipeline, or sets up separately a pipeline for nitrogen removing device.
Be only preferred embodiment of the present invention in sum, be not used for limiting practical range of the present invention.Namely all equivalences done according to the content of the present patent application the scope of the claims change and modify, and all should be technology category of the present invention.
