The specific embodiment
By describing technology contents of the present invention, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and cooperate accompanying drawing to give in detail explanation.
See also Fig. 1, the first embodiment that it has disclosed environment-friendly and energy-efficient heating furnace of the present invention comprises heating furnace body 10 and vacuum heat-insulating layer 30.
It is cylindric that heating furnace body 10 roughly is, and the cylinder chamber of heating furnace body 10 forms heating chamber 11, treats that the thermal shrinkage pipe material before the preheating goods are for example expanded carries out preheating in heating chamber 11.
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 the infrared silicon carbide ceramic 12.Certainly, the formation of heating furnace body 10 is not limited in this kind mode, can also be carborundum infrared heater or ceramic infrared heater etc.Two covers 14 are the corresponding two ends that are located at infrared silicon carbide ceramic 12 respectively, so that infrared silicon carbide ceramic 12 is fixed.
Vacuum heat-insulating layer 30 is located at outside the heating furnace body 10, is made of heating furnace body 10, middle fixed bed 31, two cappings and vacuum chamber 33, and vacuum chamber 33 is surrounded by heating furnace body 10, middle fixed bed 31, two cappings.In the present embodiment, cover 14 effect of capping of having held concurrently.
Vacuum heat-insulating layer 30 is provided with vacuum valve 34, vacuumizes by vacuum valve 34, makes vacuum chamber 33 be in vacuum state.The interface that vacuum valve 34 vacuumizes for vacuum chamber 33 can be controlled the vacuum of vacuum chamber 33.In the middle of being located at, vacuum valve 34 on the fixed bed 31, certainly, also can be located in the capping 32.
Environment-friendly and energy-efficient heating furnace of the present invention is owing to being provided with vacuum heat-insulating layer 30 outside heating furnace body 10, the vacuum state of vacuum heat-insulating layer 30 can be avoided thermal convection current, thereby can avoid heat outwards to scatter and disappear.
Further, vacuum chamber 33 inwalls of vacuum heat-insulating layer 30 are that heating furnace body 10 outer walls, middle fixed bed 31 inwalls are provided with the coating (not shown), be coated with a kind of or several in chromium, aluminium or the silver on this coating, this can make the reflect heat that is radiated on the coating go back, and avoids heat outwards to scatter and disappear.
See also Fig. 2, it has disclosed the second embodiment of environment-friendly and energy-efficient heating furnace of the present invention, and this embodiment and the first embodiment are similar, and its difference is: be provided with inner thermal insulating layer 20 between heating furnace body 10 and the vacuum heat-insulating layer 30.
