Gas exchanges are less, and moist steam is difficult discharge in vacuum drying chamber, and rate of drying is slower, and drying time is more long；And vacuum
Drying box is many times used to dry solvent boiling point sample high, and gas is expelled directly out in drying box, pollutes the environment, solvent
Cannot reclaim, also result in greatly waste.
Utility model content
The purpose of this utility model is directed to the deficiencies in the prior art, so that providing, a kind of rate of drying is fast, avoid environment
The vacuum drying chamber of pollution.
A kind of vacuum drying chamber, including vavuum pump, casing, controller and heating component, the heating component are uniformly distributed
In the bottom half, the casing is divided into three layers by dividing plate, if the uniform dry hole of the dividing plate, the bottom both sides of the casing set
There are humidity sensor and baroceptor, the casing top sets dry gas import, is installed at the dry gas import
Electric control valve, the controller connects the humidity sensor, the electric control valve and the vavuum pump so that humidity reaches most
The electric control valve opening, the vacuum pump startup are controlled during big value, humidity controls the electric control valve to close when reaching minimum value
Close；The controller connects the baroceptor to control the vavuum pump to close when air pressure reaches desired value, the control
The device connection heating component processed is to control the open and close for heating component.
Based on above-mentioned, a diameter of 1~3 cm in the hole.
Based on above-mentioned, the chamber door of the vacuum drying chamber is glass door, and the glass door is provided with the casing junction
Seal gasket.
Based on above-mentioned, dry gas import connection dry air or the drying nitrogen.
Based on above-mentioned, the gas outlet of the vavuum pump is connected with condensing unit.
The utility model compared with the prior art have substantive distinguishing features and progress, specifically, the utility model have with
Lower advantage：
1. controller described in connects the humidity sensor, the electric control valve and the vavuum pump so that humidity reaches most
The electric control valve is controlled to open during big value, the dry gas interface injects dry air or drying nitrogen, the vavuum pump
Start, moist steam discharge in the casing；Humidity reaches controller during minimum value and controls the electric control valve to close；It is described
Controller connects the baroceptor to control the vavuum pump to close when air pressure reaches desired value, is entirely vacuum dried
Journey, along with sufficient gas circulation, the moist steam is discharged in time, can largely improve rate of drying.
2. component is heated described in and is evenly distributed on the bottom half, the casing is divided into three layers, the dividing plate by dividing plate
If uniform dry hole, making the middle level and upper strata of the casing can also fully be heated, and when using, the bottom of the casing is mainly used in
Solvent sample higher is dried, the middle level or upper strata of the casing are used to dry the relatively low sample of solvent, it is to avoid sample
Influenced each other between product, improve drying efficiency.
3. the gas outlet of vavuum pump described in is connected with condensing unit, and the moist steam in the vacuum drying chamber is by described true
Empty pumped is reclaimed into the condensing unit, it is to avoid solvent pollutes environment in evaporateing into air, and recovered solvent is reused,
Save experimental cost.
