Description
Technical field
The present invention relates to holding furnace technical field more particularly to a kind of zinc, aluminium alloy electric melting and heat preservation furnace Special electrical heating
Element.
Background technique
Existing holding furnace in use, causes electric heating with solution since corrosive gas is aoxidized with electrical heating elements
Silk phenomenon of rupture, reduces service life, for this purpose, we have proposed a kind of zinc, aluminium alloy electric melting and heat preservation furnace Special electrical heating
Element.
Summary of the invention
The purpose of the present invention is to solve disadvantage existing in the prior art, and propose a kind of zinc, aluminium alloy electric smelting
Change holding furnace Special electrical heating element.
To achieve the goals above, present invention employs following technical solutions:
A kind of zinc, aluminium alloy electric melting and heat preservation furnace Special electrical heating element, including symmetrically arranged porcelain tube, the porcelain tube
Inside is fixed with superhigh temperature line electrode, and heating wire is connected between the superhigh temperature line electrode, is socketed on the outside of the porcelain tube
Glass bushing.
Preferably, one of them described porcelain tube is fixed with plate body far from the side side wall of heating wire, and plate body is close to porcelain tube
Side side wall offers symmetrically arranged limiting slot.
Preferably, one end of the glass bushing is fixed with symmetrically arranged limited block, and between limited block and limiting slot
Clamping setting.
Preferably, the side side wall of the limited block offers thread groove, and the side of the connecting plate is provided with limit spiral shell
Bolt, and be threadedly coupled between caging bolt and thread groove.
Compared with prior art, the beneficial effects of the present invention are:
By the cooperation between the glass bushing of setting, porcelain tube, heating wire, connecting plate, limited block, before can be avoided by
The heating wire phenomenon of rupture caused by corrosive gas oxidation and solution, straight cutting mode that the service life is longer can be in high-temperature condition
Direct integral replacing down improves service life, and convenient for replacing to inner components.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-2, Yi Zhongxin, aluminium alloy electric melting and heat preservation furnace Special electrical heating element, including symmetrically arranged porcelain tube
1, the inside of porcelain tube 1 is fixed with superhigh temperature line electrode 2, and heating wire 3, the outer sheath of porcelain tube 1 are connected between superhigh temperature line electrode 2
It is connected to glass bushing 4.
One of porcelain tube 1 is fixed with plate body 5 far from the side side wall of heating wire 3, and plate body 5 is close to the side side of porcelain tube 1
Wall offers symmetrically arranged limiting slot 6, and one end of glass bushing 4 is fixed with symmetrically arranged limited block 7, and limited block 7 with
Setting is clamped between limiting slot 6, the side side wall of limited block 7 offers thread groove, and the side of connecting plate 5 is provided with caging bolt
8, and be threadedly coupled between caging bolt 8 and thread groove.
Working principle: after heating wire 3 and superhigh temperature line electrode 2 are attached, then by movable glass casing 4, make
The inner sidewall of glass bushing 4 is contacted with the lateral wall of porcelain tube 1, so that glass bushing 4 is included porcelain tube 1 and heating wire 3, together
When, glass bushing 4 drives limited block 7 to enter limiting slot 6, and caging bolt 8 is tightened recently, and 4 position of glass bushing is fixed,
By the porcelain tube 1 and glass bushing 4 of setting, the heating wire as caused by corrosive gas oxidation and solution before can be avoided
3 phenomenon of ruptures, the design is simple and fast, and the heating wire as caused by corrosive gas oxidation and solution is broken before can be avoided
Phenomenon, straight cutting mode that the service life is longer, can direct integral replacing in the case of a high temperature, improve service life, and be convenient for
Inner components are replaced
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
