Heating load will be significantly greatly increased in this, as a result be exactly that heating and rate of temperature fall are all very slow, significantly waste power consumption and working efficiency.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of vacuum drying ovens of rapid temperature rise and drop, by heater and heat
Shielding is distributed in outside quartzy furnace shell, and furnace shell uses quartz material, and heat shielding is being heated using efficient gold-plated reflecting material
In the process, the radiations heat energy of heater emission directly heats product, and the entire time heated up and cooled down obtains very big shortening.
The utility model is achieved through the following technical solutions: a kind of vacuum drying oven of rapid temperature rise and drop, including control
Platform, molecular pump, main valve, furnace shell and outer furnace shell, a vacuum chamber is provided in the furnace shell, and vacuum chamber connects main valve, molecule
Pump installs the bottom of a main valve, the heating chamber of a both ends open is opened up among outer furnace shell, furnace shell passes through outer furnace shell and both ends are stretched
Out outside the two sides of an outer furnace shell, an external heat chamber, the intracavitary installation of external heat are formed between furnace shell outer wall and outer furnace shell inner wall
Having heaters, the external of heater wrap up one layer of thermal shield, and the thermal shield face heater side is reflecting surface, reflection
On the heat to furnace shell of heater, product is placed in the vacuum chamber inside furnace shell.
The furnace shell uses quartz material as a preferred technical solution, and the thermal shield is using efficient gold-plated reflection
Material.
The heater is fixedly installed in heating chamber by the screw on bracket and bracket as a preferred technical solution,
Inner wall on.
Touch screen, temperature control plate and a recorder are provided on the console as a preferred technical solution, it is described
Heater controls temperature by the temperature control plate on console.
The beneficial effects of the utility model are: heater and heat shielding are distributed in outside quartzy furnace shell by the utility model
Portion, during heating, the radiations heat energy of heater emission directly heat product, the caloric receptivity very little of quartz and outer shield,
It is entire to heat up and the time of cooling obtains very big shortening because significantly reducing thermal capacity, substantially increase energy saving and
Production efficiency.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is structural schematic diagram in the prior art；
Fig. 2 is the improved structural schematic diagram of the utility model.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Fig. 2, including console 1, molecular pump 2, main valve 3, furnace shell 4 and outer furnace shell 5, one is provided in furnace shell 4
A vacuum chamber 6, vacuum chamber 6 connect main valve, and molecular pump 2 installs the bottom of a main valve 3, opens up a both ends among outer furnace shell 5 and open
The heating chamber of mouth, furnace shell 4 passes through outer furnace shell and both ends are stretched out outside the two sides of an outer furnace shell, 4 outer wall of furnace shell and 5 inner wall of outer furnace shell
Between form an external heat chamber, the intracavitary installation having heaters 7 of external heat, one layer of thermal shield 8 of external package of heater 7,
8 face heater side of thermal shield is reflecting surface, is reflected on the heat to furnace shell of heater, product is placed in inside furnace shell
In vacuum chamber 6, it is provided with touch screen, temperature control plate and a recorder, heater 7 on console 1 and passes through the temperature on console
It controls plate and controls temperature.
In the present embodiment, furnace shell 4 uses quartz material, and thermal shield 8 is using efficient gold-plated reflecting material.Because quartz is right
The penetrance of heat radiation is 99% or more, along with efficient gold-plated radiation screen, during heating, the radiation of heater emission
Heat directly heats product.The caloric receptivity very little of quartz and outer shield because significantly reducing thermal capacity, entire heating and
The time of cooling obtains very big shortening.Substantially increase energy saving and production efficiency.
In the present embodiment, heater 7 is all made of electric heating tube or electric heating wire, passes through the spiral shell on bracket and bracket
Silk is fixedly installed on the inner wall of heating chamber.Certainly other heaters can also be used, it is not limited to above two heater.
The beneficial effects of the utility model are: heater and heat shielding are distributed in outside quartzy furnace shell by the utility model
Portion, during heating, the radiations heat energy of heater emission directly heat product, the caloric receptivity very little of quartz and outer shield,
It is entire to heat up and the time of cooling obtains very big shortening because significantly reducing thermal capacity, substantially increase energy saving and
Production efficiency.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
