Description
Technical field
The utility model relates to a kind of electrothermal device, especially a kind of for electrically heated electrothermal radiation tube.
Background technology
Current electrothermal radiation tube is comprised of heat-resisting alloy steel outer tube and heater.The outer tube seamless high temperature resistant Nie Chrome compo pipe of general employing and coiled sheet pipe, spun pipe etc.Heater is generally being had in the high temperature insulation ceramic die of spiral grooves by resistance wire.Electrothermal radiation tube is to conduct heat by radiation light-wave, and popular saying is exactly to be equivalent to transfer of air heat, and electrothermal radiation tube wants high with respect to other electrothermal tube efficiency.At present, the most of electrothermal radiation tube that adopts of industrial resistance furnace is as heating source.
But in long-term production practices, also there are problems in electrothermal radiation tube.1, the outer tube of electrothermal radiation tube is metal shell, causes and will cause ground short circuit, thereby damage heater once contact with the resistance wire of heater; If be wound with the earthenware insulation damages of resistance wire on 2 heaters; resistance wire will be scattered and with outer tube short circuit grounding; the short circuit current producing can puncture outer tube to scrap; cause the protective atmosphere in circuit to leak outside; furnace pressure reduces makes heated parts oxidation and decarbonization; produce piebald, directly affect the thermal treatment quality of institute's converted products.
Summary of the invention
The technical problems to be solved in the utility model is that existing electrothermal radiation tube internal resistance wire does not have enough protections, easily causes short circuit risk.
In order to solve the problems of the technologies described above, the utility model provides a kind of electrothermal radiation tube, comprise protective casing cylindraceous, electric heating tube, at least one ceramic support dish, the heat-resisting post of pottery, two electrode guide rods and sealing plate, the equidistant circle heating tube supported hole that is provided with on ceramic support dish, electric heating tube is snakelike bending and passes successively each heating tube supported hole, electric heating tube and ceramic support dish form cage heater jointly, cage heater and ceramic heat-resisting post are inserted in protective casing successively, sealing plate is sealed on the opening part of protective casing, two electrode guide rods are successively through being connected with the two ends of electric heating tube respectively after sealing plate and ceramic heat-resisting post, the external part of two electrode guide rods is all provided with electrode nipple, the opening part of protective casing is provided with mounting flange.
Adopt electric heating tube to avoid direct use resistance wire, effectively prevent that ground short circuit is dangerous; Adopt ceramic support dish to support electric heating tube, also can prevent that electric heating tube from contacting with protective casing; Adopt electric heating tube and ceramic support dish jointly to form cage heater and can further improve radiance; Adopt ceramic heat-resisting post to carry out thermal insulation protection to the wiring of protective casing opening part; Adopt an electric heating tube to be snakelike bending, only need two terminals, reduced wiring faults rate; Adopt electrode guide rod that electric heating tube two terminated lines are drawn outside protective casing, while having avoided back panel wiring, high temperature pairs of posts exerts an influence.
As further improvement of the utility model scheme; also comprise a fixed lever; the both sides of ceramic support dish are all provided with cylindrical boss; fixed lever successively through sealing plate, from two ends, be fixed after ceramic heat-resisting post and each ceramic support dish, the cylindrical boss of each ceramic support dish both sides docks formation protection tube successively.Adopt fixed lever by sealing plate, ceramic heat-resisting post and each ceramic support dish be connected as a single entity, and wholely in the time of can facilitating fault extracts maintenance out; Adopt the cylindrical boss of each ceramic support dish both sides to dock successively formation protection tube, can carry out high temperature protection to fixed lever.
As further restriction scheme of the present utility model, the electric heating element in electric heating tube is resistive band.Adopt resistive band as the heating element in electric heating tube, can further improve heating properties.
The beneficial effects of the utility model are: (1) adopts electric heating tube to avoid direct use resistance wire, effectively prevent that ground short circuit is dangerous; (2) adopt ceramic support dish to support electric heating tube, also can prevent that electric heating tube from contacting with protective casing; (3) adopt electric heating tube and ceramic support dish jointly to form cage heater and can further improve radiance; (4) adopt ceramic heat-resisting post to carry out thermal insulation protection to the wiring of protective casing opening part; (5) adopt an electric heating tube to be snakelike bending, only need two terminals, reduced wiring faults rate; (6) adopt electrode guide rod that electric heating tube two terminated lines are drawn outside protective casing, while having avoided back panel wiring, high temperature pairs of posts exerts an influence.
