Description
Technical field
This utility model relates to technical field of heating, is specifically related to a kind of electric heater for heat processing furnace.
Background technology
Electric heater is the electric heating equipment of a kind of international popular.After finding that power supply can occur heat effect by 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: heats is bad, heat loss is higher, poor stability, and service life is low, generally uses the life-span just 8-10 month, for production line of batch, use cost is high, and maintenance difficulties is big, and safeguards 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 electric heater for heat processing furnace, solves above-mentioned existing technological deficiency.
Scheme of the present utility model is as follows: a kind of electric heater for heat processing furnace, including U-shaped electrothermal tube, radial canal flange and adpting flange；Described U-shaped electrothermal tube includes metal tube and resistance wire；Being provided with resistance wire in the U-shaped end of described metal tube, resistance wire end connects 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 U-shaped electrothermal tubes are respectively provided with by two ends are fixed；It is provided with support bar in the middle of described U-shaped electrothermal tube；It is additionally provided with radial canal muff between described U-shaped electrothermal tube and adpting flange.
Further, the middle part of described U-shaped electrothermal tube is provided with the fixed plate for fixing support.
Further, the end of described support bar is provided with support disk.
The beneficial effects of the utility model are: simple in construction of the present utility model, deft design；Magnesia powder compacted lift in U-shaped electrothermal tube has completely cut off resistance wire in adstante febre and air contact, the time of reduction oxidation reaction；Reduce thermal loss further by radial canal muff, electric heater can be brought up to 26-30 month from 8-10 month average life, improve production efficiency, greatly reduce cost, decrease maintenance cost.

Fig. 1 is sectional structure schematic diagram of the present utility model；
Fig. 2 is the structural representation of right view of the present utility model；
Fig. 3 is the structural representation of the U-shaped electrothermal tube of this utility model.
Wherein: 1, radial canal muff；2, U-shaped electrothermal tube；3, fixed plate；4, radial canal flange；5, support bar；6, adpting flange；7, support disk；21, metal tube；22, magnesia powder compacted lift；23, eduction rod；24, resistance wire.
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 electric heater for heat processing furnace, including U-shaped electrothermal tube 2, radial canal flange 4 and adpting flange 6；Described U-shaped electrothermal tube 2 includes metal tube 21 and resistance wire 24；It is provided with resistance wire 24 in the U-shaped end of described metal tube 21, resistance wire 24 end connects eduction rod 23, gap between described resistance wire 24, eduction rod 23 and metal tube 21 is provided with magnesia powder compacted lift 22, magnesia powder compacted lift 22 has completely cut off resistance wire at adstante febre and air contact, reduce the time of oxidation reaction, there is heat conduction good, the feature of homogeneous heating, heat transmission is carried out by metal tube 21, compared with traditional air conduction, can realize quickly heating, the efficiency of heating surface is greatly improved；Adpting flange 6 and radial canal flange 4 that some groups of U-shaped electrothermal tubes 2 are respectively provided with by two ends are fixed；Being provided with support bar 5 in the middle of described U-shaped electrothermal tube 2, support bar 5 upper end is provided with screw thread, U-shaped electrothermal tube 2 is screwed in and is fixed in radial canal muff 1；It is additionally provided with radial canal muff 1 between described U-shaped electrothermal tube 2 and adpting flange 6, the setting of radial canal muff 1 makes the connection between U-shaped electrothermal tube 2 and adpting flange 6 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 26-30 month from 8-10 month average life, improves production efficiency, greatly reduces cost, it is also possible to reduces maintenance cost, reduce labor intensity.
The middle part of described U-shaped electrothermal tube 2 is provided with the fixed plate 3 for fixing support, and fixing support effect is more preferable, and in heating process, U-shaped electrothermal tube 2 is not easy the flexural deformation occurring causing because of thermal deformation, thus affects the normal of equipment and effectively run.
The end of described support bar 5 is provided with support disk 7, support bar 5 fixing for electric heater, and support bar 7 also has certain guide effect, support disk 7 fixing for support bar 5, is arranged on support effect on work surface good.
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.
