Summary of the invention
It is an object of the present invention to provide heating evenly with the resistance furnace of energy-conservation raising heats.
The present invention is achieved through the following technical solutions:
Improving the resistance furnace of heats, including body of heater, also include that oil groove and crucible, described oil groove are arranged in the middle part of described body of heater cavity, described crucible is arranged in oil groove, is provided with heating element heater between described oil groove and body of heater.
Further, to better implement the present invention, it is specifically arranged to following structure: described oil groove is built with conduction oil.
Further, to better implement the present invention, it is specifically arranged to following structure: described conduction oil includes that mineral oil origin conduction oil and synthesis type conduction oil, described mineral oil origin conduction oil include YD, YD, SD, JD and X6D, and the temperature range used is 50 DEG C-340 DEG C；Described synthesis type conduction oil includes biphenyl-biphenyl ether mixture, and the temperature range used is 50 DEG C-360 DEG C.
Further, to better implement the present invention, it is specifically arranged to following structure: on the cavity wall of described body of heater, be provided with heat-insulation layer.
Further, to better implement the present invention, it is specifically arranged to following structure: the material of described heat-insulation layer is phenol formaldehyde foam.
Further, to better implement the present invention, it is specifically arranged to following structure: described heating element heater is resistance wire, being arranged in outside described oil groove of the uniform curl of described resistance wire.
Further, to better implement the present invention, it is specifically arranged to following structure: described crucible oral area is provided with the sealing lid matched with crucible oral area；Described sealing covers the pore being provided with band plug.
The present invention compared with prior art, has the following advantages and beneficial effect:
One, the present invention is by arranging oil groove, adds conduction oil, crucible is put into oil groove in oil groove, by Resistant heating conduction oil, and then heat-conducting oil heating crucible, conduction oil is as the medium of heating so that crucible is heated evenly, has reached more preferable heats.
Two, the present invention is by arranging heat-insulation layer at body of heater cavity inner wall, it is suppressed that distributing of heat, serves the purpose of heat preservation energy-saving.
Three, the heater element resistance silk of the present invention is arranged to helical form, and oil groove is placed in the helical form cavity of formation, and the contact area of such layout heating element heater and heated conduction oil is bigger, is more beneficial for improving the rate of heat addition.
Four, filling conduction oil rather than water in oil groove of the present invention, the temperature range of use is wider, and maximum heating temperature is the highest, and the frequency adding conduction oil is the lowest.
