Abstract
The invention discloses a vacuum drying oven heater and a vacuum drying oven and relates to environmental test devices. The vacuum drying oven heater comprises a heater tube nest unit and further comprises two vacuum discharge preventing units, and the vacuum discharge preventing units are arranged at the positions close to the two ends of the heater tube nest unit respectively. Compared with the prior art, discharge of heating tube connecting wires under the vacuum condition is avoided, and the sealing effect of an oven body is improved.
Description
Technical field
The invention belongs to environmental test equipment field, particularly a kind of vacuum drying chamber heater, vacuum drying chamber and anti-vacuum discharge method.
Background technology
The mounting means of present vacuum drying chamber heater is all arranged in vacuum drying chamber by heater, the plant-grid connection of heater is realized by power line and binding post, under high vacuum state, this mode can produce vacuum discharge, and binding post sealing also comparatively bothers.
Summary of the invention
An object of the present invention is just to provide a kind of vacuum drying chamber heater, and this vacuum drying chamber heater avoids the sealing effectiveness that heating tube wiring is discharged under vacuo and improve casing.
Technical scheme is: a kind of vacuum drying chamber heater, comprises heater tubulation unit, and described vacuum drying chamber heater also comprises anti-vacuum discharge unit, and anti-vacuum discharge unit has two, is separately positioned on the two ends place closing on heater tubulation unit.
As preferably, described anti-vacuum discharge unit is 100-200mm with the spacing of the heater tubulation unit termination closed on.
As preferably, described anti-vacuum discharge unit comprises vacuum flange dish and carbon steel nut, and vacuum flange dish and carbon steel nut are installed in heater tubulation unit circumferentially.
As preferably, described vacuum flange dish is provided with vacuum drying chamber contact internal walls face, and face is provided with sealing ring installation position to vacuum drying chamber contact internal walls.
As preferably, the described carbon steel nut distance of closing between vacuum flange dish one end and vacuum drying chamber contact internal walls face is vacuum drying chamber interior wall wall thickness.
Two of object of the present invention is to provide a kind of vacuum drying chamber.
Technical scheme is: a kind of vacuum drying chamber, comprises vacuum drying chamber interior wall and vacuum drying chamber heater, and described vacuum drying chamber heater is above-mentioned vacuum drying chamber heater, and described sealing ring installation position is provided with sealing ring.
As preferably, described sealing ring is rubber seal.
As preferably, described vacuum flange dish and heater tubulation unit circumference full weld.
Three of object of the present invention is a kind of method providing anti-vacuum drying chamber vacuum discharge.
Technical scheme is: a kind of method of anti-vacuum drying chamber vacuum discharge, and the method adopts above-mentioned vacuum drying chamber, and this vacuum drying chamber is by heating tube directly through vacuum drying chamber interior wall, and heating tube is at case external connection.
Compared with prior art, beneficial effect of the present invention is:
Heater tubulation unit connection end is designed to vacuum flange disk-form by the present invention.Heater tubulation unit designs vacuum flange dish by heater tubulation unit directly through vacuum drying chamber interior wall, heater tubulation unit and vacuum drying chamber interior wall are sealed by rubber seal nut check, greatly improve the sealing effectiveness of whole equipment like this.Because heating tube is at case external connection, be at normal atmospheric pressure, doing so avoids vacuum discharge phenomenon, be highly suitable for vacuum heating apparatus and use, sealed by vacuum flange dish and cabinet wall, sealing means and sealing effectiveness are all better than the mode of traditional wired terminal.
