Description
Technical field
This utility model relates to technical field of heating, is specifically related to a kind of heat-treatment furnace heater.
Background technology
Electric heater is the equipment that a kind of international popular converts electric energy to heat energy.After finding that power supply can occur heat effect by resistance wire, the most many inventors engage in research and the manufacture of various electric heating appliance in the world.Electrical heating is the process converting electrical energy into heat energy, for liquid, the intensification of gaseous medium of flowing, be incubated, heat.Heating chamber by electric heater under pressure when adding thermal medium, in using thermodynamic fluid principle uniformly to work heating, produced heat rationally carries, and makes heated medium temperature reach user's technological requirement.
At present, electric heater is widely used in Technology for Heating Processing, especially uses the most in heat-treatment furnace.But the electric heater of the overwhelming majority also exists following defect: heat loss is higher, poor stability, and service life is low, generally using the life-span just 8-10 month, for production line of batch, use cost is high, maintenance difficulties is big, and safeguard that labor intensity is big, energy resource consumption is high, thus have impact on the reliability of electric heater.
Utility model content
The purpose of this utility model is to provide a kind of heat-treatment furnace heater, solves above-mentioned existing technological deficiency.
Scheme of the present utility model is as follows: a kind of heat-treatment furnace heater, including electrothermal tube, radial canal flange and adpting flange；Described electrothermal tube includes metal tube and resistance wire；Being provided with resistance wire in described metal tube, resistance wire two ends connect eduction rod, is provided with magnesia powder compacted lift in the gap between described resistance wire, eduction rod and metal tube；Adpting flange and radial canal flange that some groups of electrothermal tubes are respectively provided with by two ends are fixed；Described electrothermal tube is provided with ceramics bracket near radial canal flange one end, is provided with separate terminal enclosure outside ceramics bracket；Being provided with support bar in the middle of described electrothermal tube, support bar passes separate terminal enclosure；Radial canal muff it is additionally provided with between described electrothermal tube and adpting flange.
Further, the middle part of described electrothermal tube is provided with the fixed plate for fixing support.
Further, it is evacuated state in described separate terminal enclosure.
The beneficial effects of the utility model are: simple in construction of the present utility model, deft design；Magnesia powder compacted lift in electrothermal tube can completely cut off air, because exposed aerial resistance wire is compacted into magnesia powder compacted lift by metal tube magnesia powder, completely cut off resistance wire at adstante febre and air contact, reduced the time of oxidation reaction, increase substantially the life-span of heater；Reduce thermal loss further by radial canal muff, electric heater can be brought up to 28-32 month from 8-10 month average life, improve production efficiency, greatly reduce cost, decrease maintenance cost.

Fig. 3 is the structural representation of this utility model electrothermal tube.
Wherein: 1, separate terminal enclosure；2, ceramics bracket；3, radial canal muff；4, electrothermal tube；5, fixed plate；6, radial canal flange；7, support bar；8, adpting flange；41, metal tube；42, eduction rod；43, resistance wire；44, magnesia powder compacted lift.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
As shown in Figure 1 to Figure 3, a kind of heat-treatment furnace heater, including electrothermal tube 4, radial canal flange 6 and adpting flange 8；Described electrothermal tube 4 includes metal tube 41 and resistance wire 43；It is provided with resistance wire 43 in described metal tube 41, resistance wire 43 two ends connect eduction rod 42, gap between described resistance wire 43, eduction rod 42 and metal tube 41 is provided with magnesia powder compacted lift 44, magnesia powder compacted lift 44 can completely cut off air, has heat conduction good, the feature of homogeneous heating, heat transmission is carried out by metal tube 41, compared with traditional air conduction, it is possible to achieve quickly heat, the efficiency of heating surface is greatly improved；Adpting flange 8 and radial canal flange 6 that some groups of electrothermal tubes 4 are respectively provided with by two ends are fixed；Described electrothermal tube 4 is provided with ceramics bracket 2 near radial canal flange 6 one end, is provided with separate terminal enclosure 1 outside ceramics bracket 2；Being provided with support bar 7 in the middle of described electrothermal tube 4, support bar 7 upper end is provided with screw thread, electrothermal tube 4 is screwed in and is fixed in radial canal muff 3, and support bar 7 is through separate terminal enclosure 1；It is additionally provided with radial canal muff 3 between described electrothermal tube 4 and adpting flange 8, the setting of radial canal muff 3 makes the connection between electrothermal tube 4 and adpting flange 8 the most firm, heat dissipation capacity is greatly reduced, heat energy is made to be fully utilized, reduce the loss of heat, thus reduce the consumption of electric energy, improve work efficiency, there is the feature of energy-conserving and environment-protective.This electric heater can bring up to electric heater 28-32 month from 8-10 month average life, improves production efficiency, greatly reduces cost, it is also possible to reduces maintenance cost, reduce labor intensity.Because exposed aerial resistance wire 43 is compacted into magnesia powder compacted lift 44 by 41 magnesia powders of metal tube, completely cuts off resistance wire 43 at adstante febre and air contact, reduced the time of oxidation reaction, increase substantially the life-span of heater.The lower end of described support bar 7 is provided with disk, and fixing for support bar 7, support bar 7 also has certain guide effect.
The middle part of described electrothermal tube 4 is provided with the fixed plate 5 for fixing support, and fixing support effect is more preferable, and in heating process, electrothermal tube 4 is not easy the flexural deformation occurring causing because of thermal deformation, thus affects the normal of equipment and effectively run.
Being evacuated state in described separate terminal enclosure 1, make electrothermal tube 4 two ends all seal heat insulation, heat scatters and disappears less, and the thermal efficiency is higher, and ensures the starvation of wire harness, reduces by degree of oxidation, and aging speed is slower, and the life-span is longer.
Although above detailed description of the invention of the present utility model to be given detailed description and explanation; but it should be noted that; we can carry out various equivalence according to conception of the present utility model to above-mentioned embodiment and change and amendment; function produced by it still without departing from description contained spiritual time, all should be within protection domain of the present utility model.
