Abstract
The utility model discloses a kind of vacuum drying chamber, including drying box, vavuum pump and vacuum pipe, one end of the vacuum pipe connects with the drying box, the other end is connected with the vavuum pump, it is characterised in that two side external surface upper berths of the drying box set condensation water interlayer, the top of the condensation water interlayer sets delivery port, the bottom of the condensation water interlayer sets water inlet, and the bottom lowest part of the drying box draws a conduit, and the catheter tip is connected with a recycling can.The vacuum drying chamber can be dried to the material containing different boiling solvent and the condensing solvent accumulated in drying box bottom reclaimed simultaneously, drying process is carried out towards positive direction all the time.
Description
Technical field
The utility model is related to vacuum drying field, more particularly to a kind of vacuum drying chamber.
Background technology
Vacuum drying chamber is used to dry with thermal sensitivity, easily decompose and some unstable chemcial properties such as oxidizable thing
Matter, is continuously taken away the air in drying box by specific vavuum pump, it is to avoid product is directly and air contact；Meanwhile, bear
Depress the boiling point reduction of solvent, it is to avoid high temperature drying damages materials quality.
Material in drying box is by heat radiation or transmission of heat by contact come heated material, the solvent boiling point in one side material
Reduced with the raising of vacuum, while being aided with the continuous dehumidifier reduction drying box internal solvent steam content of vavuum pump so that
Solvent in material obtains enough energy and departs from surface of material, and the steam of generation is taken away by vavuum pump again so that dry all the time
Carried out towards positive direction.Most of vacuum drying chamber on sale in the market is for the moisture in dried material, heating side
Using the steam heating for comparing main flow, boiling point can be reduced water formula with the reduction of vacuum under vacuum, be aided with dry
Dry casing outside is subject to insulation material so that overall temperature all under vacuum conditions on the boiling point of water in drying box, because
This water is difficult condensation in drying box, and the vapor of generation will be taken away by vavuum pump.
But in Fine Chemical, what is often contained in dry material is not water, but various solvents,
The boiling point of these solvents is high or low, higher particularly with contained solvent boiling point in material, but with thermal sensitivity, to drying temperature
For the very harsh product of degree, the one side drying temperature composition that can be destroyed in product too high, temperature in another aspect drying box
Degree does not reach the boiling point of solvent so that these partial solvents volatilized from material run into drying box inwall will occur it is cold
Solidifying, the solvent of condensation can flow to drying box bottom along drying box inwall, evaporation is heated again, so in drying box
A cyclic process for evaporation-condensation-re-evaporation will be formed in vivo, and only little solvent that steams is taken away by vavuum pump,
Major part can always be circulated in drying box.
Utility model content
The technical problems to be solved in the utility model is to provide and a kind of the material containing different boiling solvent can be done
Vacuum drying chamber that is dry and being reclaimed to the condensing solvent accumulated in drying box bottom simultaneously.
The technical solution of the utility model is：A kind of vacuum drying chamber, including drying box, vavuum pump and vacuum pipe,
One end of the vacuum pipe is connected with the drying box, and the other end is connected with the vavuum pump, it is characterised in that described dry
Two side external surface upper berths of dry casing set condensation water interlayer, and the top of the condensation water interlayer sets delivery port, the condensed water
The bottom of interlayer sets water inlet, and the bottom lowest part of the drying box draws a conduit, the catheter tip and one time
Closed cans is connected.
The recycling can end is equipped with valve.
The utility model proposes vacuum drying chamber two side external surface upper berths of drying box set condensation water interlayer and
A conduit is drawn in the bottom lowest part of drying box, catheter tip is connected with a recycling can, such drying box both sides
Temperature is consistently lower than the boiling point of solvent, the solvent for steaming run into uphill process drying box both sides inwall will produce it is cold
Dew is condensed, and drying box bottom can be flowed to along drying box inwall, the solvent for flowing to the condensation of drying box bottom will
It imported into recycling can, it is to avoid the solvent of condensation is heated again, so as to being carried out to the material containing different boiling solvent
Dry and the condensing solvent to accumulating in drying box bottom is reclaimed simultaneously, drying process is entered towards positive direction all the time
OK.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model vacuum drying chamber front is seen.
Fig. 2 is the structural representation that the utility model vacuum drying chamber side is seen.
Specific embodiment
Such as Fig. 1 and Fig. 2, the utility model proposes vacuum drying chamber, including drying box 10, vavuum pump and vacuum pipe
（All it is not drawn into vavuum pump and vacuum pipe figure）, one end of vacuum pipe connects with drying box 10, the other end and vavuum pump
Connection, two side external surface upper berths of drying box set condensation water interlayer 20, and the top for condensing water interlayer 20 sets delivery port 21, cold
The bottom of solidifying water interlayer 20 sets water inlet 22, and the bottom lowest part of drying box 10 draws a conduit 30, the end of conduit 30
Connected with a recycling can 40.Condensed water to lower on, so ensure that the temperature of drying box both sides is consistently lower than the boiling point of solvent,
The both sides inwall that the solvent for steaming runs into drying box in uphill process will produce condensation and dewfall, and can be along drying box
Inwall flows to drying box bottom, and the solvent for flowing to the condensation of drying box bottom will be flowed into recycling can through conduit, kept away
The solvent for having exempted from condensation is heated again.
The end of recycling can 40 is equipped with valve 41, for drying at the end of by the solvent vent in recycling can.Other recycling can
Consolidation process need to be entered, to prevent crimp under vacuum.
Such as Fig. 2, condensate pipe 23 is provided with condensation water interlayer.
The utility model effectively can be dried and simultaneously to accumulating in drying to the material containing different boiling solvent
The condensing solvent of bottom half is reclaimed, and ensures that drying process is carried out towards positive direction all the time.
Specific embodiment above is only used to illustrate design of the present utility model, and one of ordinary skill in the art exists
Various deformation and change can be made under design of the present utility model, these deformations and change are included in guarantor of the present utility model
Within the scope of shield.
