Abstract
The utility model discloses a heating apparatus for the vacuum heat treating furnace. The utility model is suitable for the vacuum heat treating of the precise alloy, the elastic material, the diamond, etc. The utility model is characterized in that a heating chamber 5 is a stainless steel tube. The stainless steel tube is brilliant and clean, and the stainless steel tube has good compactness performance, and the stainless steel tube is easy to obtain the high vacuum. Resistance wires 4 which are used as a heating element are uniformly winded on the outer wall of the heating chamber 5. A heat insulating layer 3 and a heat preservation tile 6 capable of opening and closing are wrapped on the outer layers of the resistance wires 4. When the temperature is lifted, the heat preservation tile 6 is closed. When the temperature is dropped, the heat preservation tile 6 is opened. An outer shell in which a cooling water pipeline is passed is arranged on the outermost layer of the device. The device has the advantages of handy and compact structure, uniform heating in a heating chamber, high vacuum degree, and small deformation. The element processed has uniform heating.
Description
The utility model relates to a kind of vacuum heat treatment furnace heater, is applicable to Precise Alloy, elastomeric material, the vacuum heat of materials such as diamond.
The vacuum heat treatment furnace that extensively adopts mostly is case structure at present, heating clamber material great majority adopt silicate or alumina firebrick, with heating element heater with special fixtures be distributed in heating clamber around, as JP010427, the disclosed vacuum heat treatment furnace of CN2037459V.The vacuum heat treatment furnace integral body of said structure is heavy, and power consumption is big, limits because of heating clamber material compactness in addition, is difficult to the vacuum that reaches higher.
It is lightly compact that the purpose of this utility model provides a kind of structure, and heating clamber is heated evenly, and heating clamber material compactness is good, can reach the vacuum heat treatment furnace heater of high vacuum.
The utility model is achieved in that the material of heating clamber 5 is a stainless steel tube, and its inner surface light cleaning easily realizes high vacuum.On the outer wall of heating clamber 5, twining resistance wire 4 equably as heating element heater, be with porcelain bead and heating clamber 5 insulation on the resistance wire 4, heating clamber 5 is heated evenly.Skin at resistance wire is enclosed with thermal insulation layer 3, but the skin of thermal insulation layer is fixed with heat insulation tile 6 foldings, promptly closes up when heating up, and opens when needing cooling, thereby has improved intensification and cooling rate.The outermost layer of this device is the body of heater shell 7 that cooling water pipeline is arranged.Both sides at heating clamber 5 are surrounded with cooling jacket 2 respectively, so that make heat be difficult for being delivered to the diffusion pump cold-trap of fire door peep hole and stove tail, make the heating heat be difficult for loss, have guaranteed to add thermal effect.At heating clamber 5 two ends, be respectively fire door 1 and vacuum exhaust pipe 8.
The utility model compared with prior art has following advantage:
1. the utility model adopts the material of stainless steel tube as heating clamber 5, makes inboard wall of furnace body light cleaning, and compactness is good, is easy to reach high vacuum.
2. heating clamber 5 outer wall uniform winding have resistance wire 4 as heating element heater, and heating clamber 5 is heated evenly, and the items distortion is little.
3. this apparatus structure compactness, floor space is little, and it is low to consume energy.

Fig. 2 is this device heat insulation tile structural representation, is heat insulation tile 6 state when opening among the figure.
1----fire door among the figure, the 2----cooling jacket, the 3----thermal insulation layer,
The 4----resistance wire, the 5----heating clamber, the 6----heat insulation tile,
The 7----shell, 8----vacuum exhaust pipe, 9----support plate.
The invention will be further described below in conjunction with embodiment:
Claims (3)
1, a kind of vacuum heat treatment furnace heater, it is characterized in that, heating clamber 5 is the stainless steel tube material, on the outer wall of heating clamber 5, be wound with resistance wire 4 equably as heating element heater, the skin of resistance wire 4 is enclosed with thermal insulation layer 3, the skin of thermal insulation layer 3 is fixed with heat insulation tile 6, and the outermost layer of this device is the body of heater shell 7 that cooling water pipeline is housed, and heating clamber 5 two ends are fire door 1 and vacuum exhaust pipe 8.
2, device according to claim 1 is characterized in that heat insulation tile 6 is opening and closing type, promptly closes up when heating up, and opens when needing cooling.
3, device according to claim 1 is characterized in that being surrounded with cooling jacket 2 respectively on the both sides of heating clamber 5.
