Detailed description of the invention
By describing technology contents of the present invention, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1, there is disclosed the first embodiment of environment-friendly and energy-efficient heating furnace of the present invention, comprise heating furnace body 10 and vacuum heat-insulating layer 30.
Roughly cylindrically, the cylinder chamber of heating furnace body 10 forms heating chamber 11 to heating furnace body 10, treat preheating goods such as expand before thermal shrinkage pipe material in heating chamber 11, carry out preheating.
In the present embodiment, heating furnace body 10 comprises infrared silicon carbide ceramic 12, heating wire 13 and two covers 14.The cylinder chamber of silicon carbide ceramic 12 forms heating chamber 11.Heating wire 13 is looped around on infrared silicon carbide ceramic 12.Certainly, the formation of heating furnace body 10 is not limited in this kind of mode, can also be carborundum infrared heater or ceramic infrared heater etc.Two covers 14 are the corresponding two ends being located at infrared silicon carbide ceramic 12 respectively, to be fixed by infrared silicon carbide ceramic 12.
Vacuum heat-insulating layer 30 is located at outside heating furnace body 10, is made up of heating furnace body 10, middle fixed bed 31, two capping and vacuum chamber 33, and vacuum chamber 33 is surrounded by heating furnace body 10, middle fixed bed 31, two capping.In the present embodiment, cover 14 has been held concurrently the effect of capping.
Vacuum heat-insulating layer 30 is provided with vacuum valve 34, is vacuumized by vacuum valve 34, makes vacuum chamber 33 be in vacuum state.Vacuum valve 34 is the interface that vacuum chamber 33 vacuumizes, and can control the vacuum of vacuum chamber 33.Vacuum valve 34 is located on middle fixed bed 31, certainly, also can be located in capping 32.
Environment-friendly and energy-efficient heating furnace of the present invention owing to being provided with vacuum heat-insulating layer 30 outside heating furnace body 10, and the vacuum state of vacuum heat-insulating layer 30 can avoid thermal convection current, thus heat can be avoided outwards to scatter and disappear.
Further, vacuum chamber 33 inwall of vacuum heat-insulating layer 30 and heating furnace body 10 outer wall, middle fixed bed 31 inwall are provided with coating (not shown), this coating is coated with the one or several in chromium, aluminium or silver, this can make the reflect heat be radiated on coating go back, and avoids heat outwards to scatter and disappear.
Refer to Fig. 2, there is disclosed the second embodiment of environment-friendly and energy-efficient heating furnace of the present invention, this embodiment and the first embodiment similar, its difference is: be provided with inner thermal insulating layer 20 between heating furnace body 10 and vacuum heat-insulating layer 30.
