Compared with the prior art, the utility model discloses the sealed effect that the heating pipe wiring discharges and improved the box has been avoided under the vacuum.
Description
Technical field
This utility model belongs to environmental test equipment field, particularly to a kind of vacuum drying oven heater.
Background technology
Vacuum drying oven is all to be arranged in vacuum drying oven by heater now, the plant-grid connection of heater
Being realized by power line and binding post, under high vacuum state, this mode can produce vacuum discharge, and
And binding post seals and the most more bothers.
Utility model content
One of the purpose of this utility model is that a kind of vacuum drying oven heater of offer, this vacuum drying oven
Heater avoids and adds the sealing effectiveness that heat pipe wiring is discharged under vacuo and improve casing.
Technical scheme is: a kind of vacuum drying oven heater, including heater tubulation unit, described vacuum
Drying baker heater also includes that anti-vacuum discharge unit, anti-vacuum discharge unit have two, be separately positioned on and face
At the two ends of nearly heater tubulation unit.
As preferably, described anti-vacuum discharge unit with the spacing of the heater tubulation unit termination closed on is
100-200mm。
As preferably, described anti-vacuum discharge unit includes vacuum flange dish and carbon steel nut, vacuum flange dish
It is installed on heater tubulation unit circumference with carbon steel nut.
As preferably, described vacuum flange dish is provided with vacuum drying oven contact internal walls face, in vacuum drying oven
Sealing ring installation position it is provided with on wall contact surface.
As preferably, described carbon steel nut close on vacuum flange dish one end and vacuum drying oven contact internal walls face it
Between distance for vacuum drying chamber interior wall wall thickness.
The two of the purpose of this utility model are to provide a kind of vacuum drying oven.
Technical scheme is: a kind of vacuum drying oven, including vacuum drying chamber interior wall and vacuum drying oven heating
Device, described vacuum drying oven heater is above-mentioned vacuum drying oven heater, on described sealing ring installation position
Sealing ring is installed.
As preferably, described sealing ring is rubber seal.
As preferably, described vacuum flange dish and heater tubulation unit circumference full weld.
Compared with prior art, the beneficial effects of the utility model are:
Heater tubulation unit connection end is designed to vacuum flange disk-form by this utility model.Arrange at heater
Vacuum flange dish is designed by heater tubulation unit directly through vacuum drying chamber interior wall, heater on pipe unit
Tubulation unit is sealed by rubber seal nut check with vacuum drying chamber interior wall, improves so greatly
The sealing effectiveness of whole equipment.Owing to adding heat pipe at case external connection, it is at normal atmospheric pressure, thus
Avoid vacuum discharge phenomenon, be highly suitable for vacuum heating apparatus and use, by vacuum flange dish and casing
Inner wall sealing, sealing means and sealing effectiveness are better than the mode of traditional wired terminal.
Accompanying drawing explanation
Fig. 1 is this utility model vacuum drying oven heater schematic diagram；
Fig. 2 is this utility model anti-vacuum unit structural representation；
Fig. 3 is that this utility model vacuum drying oven structural diagrams is intended to；

Sealing ring 4 is arranged on sealing ring installation position 24.
Vacuum flange dish 21 and heater tubulation unit 1 circumference full weld.
Heater tubulation unit 1 terminal design is become vacuum ring flange form by this utility model.At heater
Vacuum flange dish is designed by heater tubulation unit 1 directly through vacuum drying chamber interior wall 3 on tubulation unit 1,
Heater tubulation unit 1 is locked close with vacuum drying chamber interior wall 3 by rubber seal carbon steel nut 23
Envelope, so greatly improves the sealing effectiveness of whole equipment.Owing to adding heat pipe at case external connection, it is at mark
Under quasi-atmospheric pressure, thus avoid vacuum discharge phenomenon, be highly suitable for vacuum heating apparatus and use, logical
Crossing vacuum flange dish to seal with cabinet wall, sealing means and sealing effectiveness are better than the side of traditional wired terminal
Formula.
