Description
Technical field
The utility model belongs to chemical engineering experiment equipment technical field, and in particular to a kind of vacuum drying for preventing powder from splashing
Case.
Background technology
Vacuum drying chamber is widely used in biochemistry, and chemical pharmaceutical, health care, agri-scientific research, environmental protection etc. is ground
Study carefully application field, be used as powder dry, bake and bank up with earth and all kinds of glass containers sterilization and sterilizing.It is particularly suitable for drying temperature-sensitive
Property, easily decompose, readily oxidizable substance and complicated ingredient article carry out drying process rapidly and efficiently.Vacuum drying chamber is dry compared with conventional
Dry technology possesses following advantage：(1) vacuum environment greatly reduces the boiling point for the liquid for needing to drive away, so vacuum drying can be with
It is readily applied to heat-sensitive substance；(2) for being not easy dry sample, such as powder or other graininess samples, using true
Empty seasoning can effectively shorten drying time；(3) the complicated mechanical part of various constructions or other porous samples are through over cleaning
Boulton process is used afterwards, does not stay any residual substance after being completely dried；(4) using safer ----in vacuum or inert conditions
Under, the possibility of oxide heat blast is completely eliminated.But vacuum drying chamber is put for when drying powder material, opening air outlet valve
Gas, a large amount of gases enter in vacuum drying chamber, huge draught head so that powder material splashes, and causes loss of material, pollutes
It is dried in vacuo box body.
Therefore, developing a kind of vacuum drying chamber for preventing powder from splashing turns into urgent problem to be solved.
Utility model content
The utility model provides a kind of vacuum drying chamber for preventing powder from splashing, and can effectively reduce huge pressure during deflation
Power is poor, it is to avoid powder material splashes.
The utility model solve the technical scheme that is used of technical problem for：
A kind of vacuum drying chamber for preventing powder from splashing, including casing, chamber door, built-in heating coil, vacuum meter, vacuum
Pump, air inlet, intake valve, gas outlet, air outlet valve and the first appendix, the vavuum pump and gas outlet by the first appendix and
Air outlet valve is connected, in addition to fluid reservoir, gas distributor and the second appendix, and fluid reservoir is located at box house, the gas point
Cloth device is inside fluid reservoir, and the gas distributor is hollow ring structure, if its surface distributed has gas access and dry gas
Hole, the air inlet is connected with the gas access of gas distributor by the second appendix, and the fluid reservoir is built with higher boiling
Conduction oil.
Preferably, the vacuum drying chamber also include pressure sensor and PLC, the pressure sensor it is defeated
Go out end with the input of PLC to be connected, the output end of the PLC is connected with air outlet valve and vavuum pump.Work as casing
When interior pressure reaches setting value, PLC control air outlet valve and vavuum pump are closed successively, with energysaving effectiveness.
Preferably, the joint of the casing and chamber door is provided with sealing strip.
It is further preferred that the material of the sealing strip is rubber or silica gel.
The beneficial effects of the utility model are：
The vacuum drying chamber provided by the utility model for preventing powder from splashing, it is simple in construction, it is reasonable in design, can effectively it drop
Immense pressure when low vacuum drying case is deflated is poor, it is to avoid powder material splashes, so as to avoid material from damaging loss and be dried in vacuo
Case pollutes.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1, casing, 2, vavuum pump, 3, air inlet, 4, intake valve, 5, air outlet valve, the 6, second appendix, 7, gas point

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit the utility model.
A kind of vacuum drying chamber for preventing powder from splashing, including it is casing 1, chamber door 13, built-in heating coil, vacuum meter, true
Empty pump 2, air inlet 3, intake valve 4, gas outlet 12, air outlet valve 5, the first appendix 9, fluid reservoir 8, gas distributor 7, second are defeated
Tracheae 6, pressure sensor 10 and PLC 11, the vavuum pump 2 pass through the first appendix 9 and air outlet valve 5 with gas outlet 12
It is connected, fluid reservoir 8 is inside casing 1, and the gas distributor 7 is inside fluid reservoir 8, during the gas distributor 7 is
Empty loop configuration, its surface distributed has gas access and some stomatas, the gas access of the air inlet 3 and gas distributor 7
It is connected by the second appendix 6, the fluid reservoir 8 is built with higher boiling conduction oil；
The output end of the pressure sensor 10 is connected with the input of PLC 11, the PLC 11 it is defeated
Go out end with air outlet valve 5 and vavuum pump 2 to be connected；The joint of the casing 1 and chamber door 13 is provided with the sealing strip of quality of rubber materials.
Operation principle of the present utility model is：
Dry material will be needed to be put into casing 1, chamber door 13 is closed, intake valve 4 is closed, air outlet valve 5 and vacuum is opened
