Description

A kind of many power electrothermal tube

Technical field

The utility model relates to a kind of electrothermal tube, is meant that especially a kind of set inside has the electrothermal tube of some heating wires.

Background technology

As everyone knows; The tubulose electrothermal tube is to be shell with the metal tube; Along central shaft is to the product of distributing auger lectrothermal alloy wire in the pipe, its space padding and compacting has the magnesium oxide sand of good insulation heat conductivility, and silica gel sealing is used at mouth of pipe two ends; This metal armouring electric heating element can heated air, metal die and various liquid.The tubular metal electrothermal tube is in metal tube, to put into electric heating element, and closely is filled with the crystal magnesium oxide powder of good heat resistance, thermal conductivity and insulating properties in the gap, is forming through other PROCESS FOR TREATMENT.It has simple in structure, characteristics such as mechanical strength is high, the heat efficiency is high, safe and reliable, simple installation, long service life.Adaptable across devices such as various nitre grooves, tank, oil groove, acid-base groove, fusible metal melting furnace, air-heating furnace, drying oven, drying box, hot-dies.

Electrothermal tube is the electric elements that specially electric energy are converted into heat energy, because its low price is easy to use, easy for installation, pollution-free, is widely used in various heating occasions, and the useful life of electrothermal tube is all very long, and general design service life has more than 10000 hour.

But with regard to the electrothermal tube of present appearance, all only has single power; That is to say for the unique power of all only unique correspondence of specific electrothermal tube product; This electrothermal tube can not satisfy the diversified concrete heating requirements of people now, and this is the major defect for conventional art.

The utility model content

The utility model provides a kind of many power electrothermal tube, and its set inside has some heating wires can reach the effect that multiple power is provided through the operating state of control heating wire, and this is the main purpose for the utility model.

The technical scheme that the utility model is taked is: a kind of many power electrothermal tube, and it comprises body, heat-resisting inner core and control termination, wherein; This body is processed by metal material, and this body has inner surface and outer surface, and centers on formation one inner chamber by this inner surface of this body; This heat-resisting inner core is arranged in this inner chamber, and this heat-resisting inner core is processed by heat-resisting high-temperature material, is wound with the heating wire unit on this heat-resisting inner core; This heating wire unit comprises some heating wires; The diameter of any two these heating wires is all inequality, and this control termination is arranged on the end of this body, and some these heating wires are connected with this control termination simultaneously.

The length of any two these heating wires is all inequality.Also be provided with powder bed in this inner chamber, this powder bed is between the inner surface of this heat-resisting inner core and this body.

The beneficial effect of the utility model is: the utility model is wrapped in heating wire on this heat-resisting inner core simultaneously in practical implementation; Selected simultaneously as required different-diameter; Several groups of heating wires of length are worked simultaneously, realize the state of the many power of a pipe through the power gear controller of this control termination.

Embodiment

Shown in Fig. 1 to 2, a kind of many power electrothermal tube, it comprises body 10, heat-resisting inner core 20 and control termination 30.

Wherein, this body 10 is processed by metal material, and this body 10 has inner surface and outer surface, and by this inner surface of this body 10 around forming an inner chamber 11.

This heat-resisting inner core 20 is arranged in this inner chamber 11, and this heat-resisting inner core 20 is processed by heat-resisting high-temperature material, is wound with heating wire unit 40 on this heat-resisting inner core 20.

This heating wire unit 40 comprises some heating wires 41, and the diameter of any two these heating wires 41 is all inequality.

The length of any two these heating wires 41 is all inequality.

This control termination 30 is arranged on the end of this body 10, and some these heating wires 41 are connected with this control termination 30 simultaneously.

Can control the "on" position of each this heating wire through this control termination 30, thereby determine the operating state of each this heating wire.

Also be provided with powder bed 50 in this inner chamber 11, this powder bed 50 is between the inner surface of this heat-resisting inner core 20 and this body 10.

In practical implementation, heating wire 41 is wrapped on this heat-resisting inner core 20 simultaneously, selected simultaneously as required different-diameter, several groups of heating wires 41 of length are worked simultaneously, realize the state of the many power of a pipe through the power gear controller of this control termination 30.
