Description
Technical field
The utility model belongs to electric heating element technical field, more particularly to a kind of W types Si-Mo rod.
Background technology
Si-Mo rod is a kind of high temperature resistant being made based on molybdenum disilicide, oxidation resistant resistance heating element.In high temperature
In use, fine and close quartz (SiO2) glass-film of one layer of light of Surface Creation, can protect Si-Mo rod internal layer under oxidizing atmosphere
Do not reoxidize.Under oxidizing atmosphere, maximum operation (service) temperature is 1800 DEG C, and the resistance of Si-Mo rod increases rapidly as temperature is raised
Plus, the resistance value stabilization when temperature-resistant.Existing Si-Mo rod is mainly made up of cold end and heating part, its cold end and heating part one
As be fixedly connected by way of welding, due to Si-Mo rod in high temperature some soften, it is not only hard but also crisp during low temperature, in the mistake used
Once deforming or colliding in journey, Si-Mo rod will be broken, and the heating part of Si-Mo rod is thin and length is easiest to occur to break
Split, after the heating part of Si-Mo rod is broken, often whole Si-Mo rod can all be discarded, and so result in the waste of material；Separately
Outside, because cold end and heating part can not be dismantled, therefore space-consuming is big, is stored inconveniently and safeguards；Its cold end of existing Si-Mo rod
Often it is in integrative-structure with heating part, its length can not be adjusted, therefore there is significant limitation.
Utility model content
The utility model in order to solve weak point of the prior art there is provided a kind of simple in construction, working stability, be easy to
Dismounting, adjustable length, W type Si-Mo rods applied widely.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：W type Si-Mo rods, including W-shaped structure
Heating part and two cold ends, heating part two ends are respectively equipped with a telescoping tube, and each telescoping tube includes outer tube and inner tube, outside
Inside pipe wall is provided with internal thread, and outer wall of inner tube is provided with external screw thread, and inner tube is threaded in outer tube vertically, two outer tube lower ends point
Heating part two ends are not threaded in, and two cold ends correspond to be threaded between two inner tube upper ends, heating part outer surface respectively
Separate provided with heat emission hole.
The end face of cold end and inner tube junction opens up fluted, and bushing is embedded with groove, and inner tube top is threaded in
In bushing.
One piece of reinforcing plate is fixedly connected between two outer tubes.
Heating part is in hollow tubular structure, and heat emission hole inside heating part with being connected.
Using above-mentioned technical proposal, the utility model has the following advantages that：
1st, be provided with telescoping tube between heating part end of the present utility model and cold end, the inner and outer tubes of telescoping tube respectively with
Cold end and the connection of heating part end thread, it is easy to disassemble, can be of the present utility model to adjust by adjusting the length of telescoping tube
Length, meets needs of production.
2nd, heating part, cold end and telescoping tube use dismountable attachment structure each other, after heating part is damaged, and only need
Heating part is changed, cold end part can be reused, it is to avoid the waste of material, cost-effective, be easy to safeguard；When storage or
When person transports, heating part, cold end and telescoping tube can be split so that space-consuming is reduced.
3rd, bushing is provided between cold end and the junction of inner tube, it is to avoid inner tube and cold end turn friction for a long time so that cold
Serious wear is held, the service life of cold end is added.
4th, it is connected with reinforcing plate between two outer tubes so that overall intensity increase, work is more stablized；During heating part is in
Hollow tube-like structure, can increase the utilization rate of material, and heating part outer surface, which is spaced apart, is provided with heat emission hole, in heat emission hole and heating part
Portion is connected so that the heat inside heating part comes out, and improves radiating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, W types Si-Mo rod of the present utility model, including the heating part 1 of W-shaped structure and two cold ends 2, hair
The hot two ends of portion 1 are respectively equipped with a telescoping tube, and each telescoping tube includes outer tube 3 and inner tube 4, and the inwall of outer tube 3 is provided with internal thread,
The outer wall of inner tube 4 is provided with external screw thread, and inner tube 4 is threaded in outer tube 3 vertically, and two lower ends of outer tube 3 are threaded in respectively
The two ends of heating part 1, two cold ends 2 correspond to be threaded in two upper ends of inner tube 4 respectively, and the outer surface of heating part 1 is spaced apart and is provided with
Heat emission hole 5.
Cold end 2 and the end face of the junction of inner tube 4 open up fluted, and bushing 6 is embedded with groove, and the top screw thread of inner tube 4 connects
It is connected in bushing 6.
One piece of reinforcing plate 7 is fixedly connected between two outer tubes 3.
Heating part 1 is in hollow tubular structure, and heat emission hole 5 inside heating part 1 with being connected.
The utility model when in use, outer tube 3 is screwed and is connected to the end of heating part 1, by inner tube 4 and the spiral shell of cold end 2
Line is connected, and then cold end 2 and the correspondence of inner tube 4 are threadedly coupled with outer tube 3, according to actual needs, makes inner tube by turning inner tube 4
4 drive cold ends 2 are moved up or down, so as to be adjusted to suitable length, are placed in behind fixed position, by two 2 points of cold ends
Not with two electrode conductions, electric current produces heat by heating part 1 by resistance.
The present embodiment not makees any formal limitation, every foundation to shape of the present utility model, material, structure etc.
Any simple modification, equivalent variations and modification that technical spirit of the present utility model is made to above example, belong to this reality
With the protection domain of new technique scheme.
