Abstract
The utility model relates to an electric heating device which is characterized by comprising a furnace chamber, electric heating wires, a housing, a hydrogen pipe and a support, wherein the furnace chamber is arranged in the housing through the support, the electric heating wires are arranged on the outer surface of the furnace chamber in a coiled manner, a discharge port communicated with the furnace chamber is arranged at the front end of the housing, the hydrogen pipe is connected with the furnace chamber, the lower part of the furnace chamber is rectangular, and the upper top surface of the furnace chamber is in the shape of an arch. A fireproof heat insulation layer is further arranged on the inner wall of the housing. An insulating film is arranged on the electric heating wires. The electric heating device changes the structural form of the furnace chamber, thereby enabling materials to be in full contact with hydrogen and improving the heat transfer effect of heat radiation; furthermore, the electric heating wires are directly coiled outside the furnace chamber for heating, thereby enabling the furnace chamber to be heated in a more uniform manner, and being higher in heat transfer efficiency.
Description
Technical field
The utility model relates to a kind of electric heater unit, specifically be a kind of electric heater unit that W-Mo powder is produced that is used for.
Background technology
Tungsten is two kinds of resistant to elevated temperatures metals, for industrial development very big effect is arranged, and is widely used in welding, electronic device, and chemical industry, industrial circles such as space flight, prospect is very wide.Tungsten, molybdenum all are the inert elements in the chemical periodic table, and they all are that refractory metal consumes height, poor working environment in high temperature process.Tungsten, molybdenum are in the course of processing, and material all need be in high temperature molybdenum-wound furnace heating under the hydrogen atmosphere protection.The cabinet-type electric furnace that uses in the prior art, the boiler tube horizontal positioned, hearth door is at the burner hearth front end; Burner hearth is cuboid, and thermocouple inserts in the burner hearth from the back or the top of burner hearth, and thermo electric material is a heating wire; The shortcoming of its existence is: one side heating element skewness; It is inhomogeneous to cause fire box temperature to be heated, and furnace height is too high on the other hand, and height of materials is too low; Cause the minimizing of reducing agent hydrogen and material touch opportunity and reduced the radiant heat transfer effect, cause the consumption of energy and amounts of hydrogen all higher.
The utility model content
The purpose of utility model is the deficiency for solving the problems of the technologies described above; A kind of electric heater unit is provided, and the utility model changes the version of burner hearth, and material can fully be contacted with hydrogen; And can improve thermal-radiating heat-transfer effect; And direct coiling heating wire heats outside burner hearth, and it is more even that burner hearth is heated, and heat transfer efficiency is higher.
The utility model is the deficiency that solves the problems of the technologies described above, and the technical scheme that is adopted is: a kind of electric heater unit is characterized in that: comprise burner hearth, heating wire, housing, hydrogen pipe and bearing; Said burner hearth is arranged in the housing through bearing; The electric filament disc is around the outer surface that is arranged on burner hearth, and the housing front end is provided with the discharging opening that is communicated with burner hearth, and the hydrogen pipe is connected with burner hearth; The bottom of said burner hearth is rectangular, and last end face is arch.
The inwall of said housing also is provided with refractory insulating layer.
Said heating wire is provided with dielectric film.
The utility model changes the version of burner hearth, material can fully be contacted with hydrogen, and can improve thermal-radiating heat-transfer effect, and direct coiling heating wire heats outside burner hearth, and it is more even that burner hearth is heated, and heat transfer efficiency is higher.
Description of drawings
Fig. 1 is the utility model sectional structure sketch map.
Fig. 2 is the structural representation of the utility model burner hearth.
Fig. 3 is the utility model side-looking structural representation.
Mark among the figure: 1, burner hearth, 2, heating wire, 3, housing, 4, the hydrogen pipe, 5, bearing, 6, discharging opening.
Embodiment
As shown in the figure: a kind of electric heater unit; Comprise burner hearth 1, heating wire 2, housing 3, hydrogen pipe 4 and bearing 5, burner hearth 1 is arranged in the housing 3 through bearing 5, and heating wire 2 coilings are arranged on the outer surface of burner hearth 1; Housing 3 front ends are provided with the discharging opening 6 that is communicated with burner hearth 1; Hydrogen pipe 4 is connected with burner hearth 1, and the bottom of burner hearth 1 is rectangular, and last end face is arch.Such chamber structure has reduced the space in the burner hearth 1, material can be contacted with hydrogen more fully, and can improve thermal-radiating heat-transfer effect.Heating wire 2 coilings are arranged on the periphery of burner hearth 1, and heating wire 2 energisings are heated burner hearth 1.The inwall of housing 3 also is provided with refractory insulating layer, and heat-insulation layer can be exotic materials such as alumina silicate or rock wool, and the heat in the anti-locking apparatus spreads to the external world.Heating wire 2 is provided with dielectric film, can use the polyimide insulative film.
