Description
Technical field
The present invention relates to vacuum drying technical field, more particularly to a kind of vacuum drying chamber with captation.
Background technology
Vacuum drying chamber be it is a kind of under vacuum conditions, by heating quickly by the equipment of moisture removal in material.With it is normal
Pressure drying box is compared, and which introduces vacuum condition, the moisture in material can be caused in the temperature less than water atmospheric boiling point (100 DEG C)
Degree is lower to be vaporized, and the drying temperature in operation is generally no greater than 80 DEG C, it is ensured that active component, heat-sensitive ingredients in material without
The related activity of material must be ensured by being heated at high temperature for a long time.
From a structural point, the main modular of vacuum drying chamber includes heating and control system, vacuum system, condensation at present
System, respectively whole process of vacuum drying provide heating and control, vacuum environment and refrigerating function.Heating and control system one
As using electric heating block heat, by temp probe to drying box internal temperature carry out the real time measure, added by control system
The switching of hot block working condition (heating or insulation)；Vacuum system is typically provided by vacuum pump or oil pump；Condenser system is also known as
For " cold-trap ", it is the optional accessory of vacuum drying chamber, i.e., a set of condenser system is installed additional in vavuum pump front end, in vavuum pump and heating
When system works, volatile solvent contained by material or moisture vaporization in vacuum drying chamber, by condensed fluid storage in cold
In the drainer of solidifying system, only a small amount of water vapour is inhaled into vavuum pump, vavuum pump will not be impacted, condenser system is removed
Can be effectively in collecting box outside large quantity of moisture, while quick halogenation caused by being also avoided that after excess water suction vavuum pump,
To vavuum pump and play a protective role.The vacuum drying chamber brand of main flow in the market, such as Zhengzhou Kodak, Shanghai one it is permanent,
Upper Nereid is grand, the gloomy letter in Shanghai, Nanjing rise that prosperous, Dongguan is frequently tall and erect, German guest must wait the product of manufacturer production, employs the knot of the above
Structure designs.
But vacuum drying chamber is when to water content larger dry materials at present, after vacuum reaches sets target,
Once stop the work of vavuum pump, then the valve closed between vavuum pump and drying box cavity, under vacuum and heated condition, thing
Moisture in material volatilizees and is distributed in drying box cavity in air as water vapor, relatively low in drying box cavity inner temperature
Position such as cavity bottom and door glass form at be condensed into liquid, when the water of this partially liq is more, can suppress
Moisture is converted into vapor in material, reduces the dry materials efficiency in whole drying box cavity.In order to avoid the above situation goes out
Now, it is necessary to be always maintained at vavuum pump working condition so that moisture is constantly converted into water vapor in air in material, then can pole
Big increase energy consumption；Or vacuum is manually released, drying box is opened, the agglutinating water at drying box cavity bottom and chamber door is wiped
It is dry, promote water vapor in air in drying box cavity to be constantly converted into liquid agglutinating water, and then promote moisture in material
Vaporization process, and so can not only increase manual operation, it can also influence the drying efficiency of material in drying box.
The content of the invention
The invention provides a kind of vacuum desiccator with captation, the energy consumption for solving existing vacuum desiccator is big, dry
The problem of dry efficiency is low.
The present invention can be achieved through the following technical solutions：
A kind of vacuum drying chamber with captation, including housing, vacuum system, condensed system are provided with the housing
System, heating and control system, are additionally provided with dry cavity and captation in the housing, the dry cavity is treated for placement
Dried object, the captation are arranged on the lowest part of the vertical direction of the dry cavity, for collecting the dry cavity
Internal liquid water, and the liquid water of collection is expelled to dry containment portion.
Further, the side of the housing is provided with delivery port, and the captation includes water collector, and the water collector is used
In the liquid water that storage is collected, top is by the first valve and dries the lowest part of cavity and is connected, bottom by the second valve and
Delivery port is connected.
Further, it is stainless to be arranged to cylindrical, spherical, olive shape, cone or water-drop-shaped, use for the water collector
Steel, polytetrafluoroethylene (PTFE) or glass material are made.
Further, the integrated design of the dry cavity and captation, both junctions are provided with the first opening,
Described first is open flows into captation for drying the liquid water of inside cavity, the captation in vertical direction most
Lower is provided with the second opening, and described second is open for the liquid water of collection to be expelled into dry containment portion.
Further, the dry cavity is arranged to square, cuboid, spherical or olive shape.
Further, first valve and the second valve use manually-operated gate or electromagnetic valve.
The present invention is beneficial to be had technical effect that：
By increasing captation, the liquid water for drying inside cavity is collected and discharged, avoids dry inside cavity
Liquid water be changed into steam and be again introduced into thing to be dried and dried again, reduce energy consumption, reduce manual operation and people
Work cost, improves drying efficiency, in addition, it is simple in construction, it is easy to operate, there is very strong market popularization value.
