Description
Technical field
It the utility model is related to a kind of high vacuum multi-lay winding low-temperature (low temperature) vessel vacuum extractor.
Background technology
It is understood that high vacuum multi-lay winding low-temperature (low temperature) vessel is the container for containing cryogenic liquid, such container matter is weighed
The most important quality index of amount quality is static evaporation rate, and it is also to determine whether the product commercially has to strive power unexpectedly
Most important factor, and the height of this index is almost directly into anti-with the vacuum of high vacuum multi-lay winding low-temperature (low temperature) vessel interlayer
Than relation, therefore many manufacturers all make great efforts to improve the vacuum of high vacuum multi-lay winding low-temperature (low temperature) vessel interlayer, and
Whether whether layer vacuum high, hold time and grow, but by two factors determine one be interlayer glomus mosseae, another
It is final vacuum, and the key for improving the two factors further relates to vaccum-pumping equipment and technique.
And the part of most critical is tank body firing equipment for vaccum-pumping equipment, it is understood that in order to inner pressurd vessel appearance
In face and inner surface of outer cover and the gas of sheathing paper absorption is released, it is necessary to heated baking, general baking temperature are carried out to it
At 160 DEG C or so, temperature is too high to be caused damage to the sheathing paper in the sealing ring and interlayer of shell safety device, in the past I
Factory and many producers are heated using crawler type heating tape and ceramic heat rope mode, this mode of heating mainly have some one
A little shortcomings：
1st, non-uniform temperature, due to heating when crawler type heating tape be to ride on tank body or be placed on tank body lower part, thus
Necessarily cause the tank body of high, the remote heating tape of tank body part temperature close to heating tape low, once with thermocouple measurement tank body shell
Temperature, highest and minimum poor 100 DEG C；
2nd, the thermal efficiency is low, is heated with this mode of heating, and ceramic heat rope and tank body do not contact, and heating rope heating is empty
Gas, warmed-up air carries out heat exchange with low-temperature (low temperature) vessel tank body again, thus the thermal efficiency is very low；
3rd, heating tape and heating rope are fragile, because the structure of heating tape and heating rope is to be installed with ceramics outside resistance wire
The heat-insulating materials such as ring, radiating condition is very poor to cause resistance wire local temperature very high, and the particularly high surface of joint temperature is oxidizable,
Resistivity is higher so as to which temperature is also higher after oxidation, is finally broken here.
Utility model content
Its purpose of the utility model is that providing a kind of high vacuum multi-lay winding low-temperature (low temperature) vessel takes out
Vacuum plant, there is the characteristics of temperature is uniform, the thermal efficiency is high, electrical heating elements long lifespan.
The technical scheme realized above-mentioned purpose and taken, including heater box, the heater box bottom are provided with gas outlet, outlet
The upper end of mouth is provided with track, and the upper end of track is provided with dolly, and dolly upper end is provided with tank body, and the outside of tank body is provided with interlayer, described
The upper end of heater box is provided with fan air inlet, and the upper end of fan air inlet is provided with air-heater, and the side of air-heater is connected with electricity and added
Fever element, the side of the heater box are provided with pumped vacuum systems, and pumped vacuum systems is connected with interlayer, in the heater box also
Provided with hermatic door.
Beneficial effect
The utility model has advantages below compared with prior art.
1st, more uniform temperature, because this mode of heating is circulated by force using mechanical fan, the heat exchange of air
Quite fully, several to inlet and outlet due to designing, hot-air does not almost have dead angle when circulating in whole heater box, through with heat
Galvanic couple determines（Measurement position is respectively at the angle of top and the bottom 8 and middle part）Each measurement point temperature difference is less than 5 DEG C；
2nd, the thermal efficiency is high, and due to the heat that electrical heating heater element is sent, almost all is taken away by blower fan, and tracheae with
And heating furnace has all carried out strict Insulation, the heat exchange of air is also quite fully, therefore the thermal efficiency is higher；
3rd, electrical heating heater element long lifespan, because the heat that electrical heating heater element is sent is to force to take away by blower fan
, therefore heating part temperature would not be very high, therefore comparatively the electrical heating heater element life-span can be long.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
The present apparatus includes heater box 9, as shown in figure 1, the bottom of the heater box 9 is provided with gas outlet 7, the upper end of gas outlet 7
Provided with track 8, the upper end of track 8 is provided with dolly 6, and the upper end of dolly 6 is provided with tank body 11, and the outside of tank body 11 is provided with interlayer 10, institute
The upper end for stating heater box 9 is provided with fan air inlet 3, and the upper end of fan air inlet 3 is provided with air-heater 2, the side connection of air-heater 2
There is electrical heating heater element 1, the side of the heater box 9 is provided with pumped vacuum systems 5, and pumped vacuum systems 5 is connected with interlayer 10, institute
