Abstract
The utility model relates to an electrical heating circle, which has low cost, convenient processing and reliable capability and can use a framework time after time, wherein the framework is made up by firing the flame-proof insulating material or using other modes, the shape of the framework is a semi-cylindrical shape, and the semi-cylinder is axially arranged with a plurality of through small circular holes. A semi-cylindrical heating circle is formed by threading and winding resistance wires in the small circular holes of the semi-cylindrical framework, and a cylindrical flame-proof insulating material heating circle is formed by combining the same two semi-cylindrical heating circles together.
Description
Affiliated technical field
The utility model relates to a kind ofly can carry out electrically heated Electrothermal ring to cylinder, the cylinder position of plant equipment, especially has with low cost, easy to process, dependable performance, the reused Electrothermal ring of its skeleton.
Background technology
Present known Electrothermal ring mostly adopts and twine rich resistance wire on the micarex skeleton, and with the micarex insulation, the outside forms with the iron sheet bag pressure two sides, front and back again.This heating collar processed complex, cost be higher, use in easily electric leakage or short circuit, the life-span is short and skeleton can only disposablely use.
Summary of the invention
In order to overcome existing heating collar cost height, and skeleton can only disposable shortcoming, and the utility model provides a kind of with low cost, easy to process, dependable performance, the reused Electrothermal ring of its skeleton.
The technical scheme in the invention for solving the technical problem is: the skeleton of Electrothermal ring adopts refractory insulating material to fire or other modes process, and it is shaped as semi-cylindrical shaped, and axially-aligned the small sircle hole of several perforations on semicircular cylinder.Resistance wire is worn in the small sircle hole of semicircular cylinder skeleton, just constituted a semi-cylindrical shaped heating collar.Two identical semi-cylindrical shaped heating collars are combined, just constituted a cylindrical shape heating collar.If heating collar in use resistance wire is blown, can on former skeleton, more renew electricity silk back easily and continue to use, realized the purpose of repeatedly using and further reducing cost of heating collar skeleton.
The beneficial effects of the utility model are, this heating collar is cheap for manufacturing cost, easy to process, dependable performance, its skeleton can repeatedly be used, and has further reduced cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model plane graph.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
Among the figure 1, semi-cylindrical shaped refractory insulating material skeleton, 2, the resistance wire hole, 3, resistance wire, 4, the cross-line groove.
Embodiment
In Fig. 2 embodiment, semi-cylindrical shaped refractory insulating material skeleton (1) is by firing or other modes process, go up axially-aligned at semi-cylindrical shaped refractory insulating material skeleton (1) and several resistance wire holes (2), resistance wire (3) is worn in resistance wire hole (2) by cross-line groove (4), has just constituted a semi-cylindrical shaped heating collar.Two identical semi-cylindrical shaped heating collars are combined, just constituted a cylindrical shape refractory insulating material heating collar.
Claims (1)
- A kind of cylindrical shape refractory insulating material heating collar, it is worn on the refractory insulating material skeleton by resistance wire and constitutes, it is characterized in that: the heating collar skeleton is to be made by refractory insulating material, it is shaped as semi-cylindrical shaped, on the semi-cylindrical shaped skeleton, axially-aligned several perforations in order to wear small sircle hole around resistance wire.
