Abstract
The invention relates to a hermetic insulating electrode leading-out bar of a silicon tetrachloride radiation electric heater. A copper bar and a stainless steel bar are welded integrally, so that an electrode leading bar is constructed; the electrode leading bar is placed into a metal tube; one end of the stainless steel bar extends out of the metal tube; magnesium oxide powder is filled between the electrode leading bar and the inner wall of the metal tube; and a tube end seal is arranged at one end, which is close to the copper bar, of the metal tube. The hermetic insulating electrode leading-out bar is rolled by using tube rolling equipment, and the magnesium oxide powder can bear an air pressure of 5bar after rolling, so that the hermetic insulating performance is improved, and the hermetic insulating electrode leading-out bar is suitable for an explosion-proof occasion which is protected by being integrally charged with nitrogen; the metal tube and a furnace wall are welded together, the electrode leading bar in the metal tube at a welding position is made from the stainless steel bar, and the end part of the stainless steel bar extending out of the metal tube is welded with an electric heating wire in a furnace, so that the electrode leading bar can bear the high temperature in the furnace; and the electrode leading bar can be applied to a high-temperature occasion due to the adoption of the stainless steel bar, and the copper bar has high electrical conductivity, so that the situation of internal overheat of the leading bar caused by high carrying capacity can be avoided.
Description
Technical field:
The present invention relates to a kind of electrode lead-out rod, particularly a kind of sealed insulation electrode lead-out rod of silicon tetrachloride radiant electric heater.
Background technology:
In the radiant electric heater of industrial a lot of electric heater especially for explosion-proof occasion; often need to be in the electric heater chamber nitrogen filled protection; because heating wire and electrode draw the very difficult sealing in the place that goes out furnace chamber between rod in traditional industrial heating furnace; usually the way of usefulness is to draw the upper cover of rod insulating ceramics Guan Zaiyong heat-preservation cotton jam-pack; but this method is for the electric heater equipment that uses in explosion-proof occasion and inapplicable, and difficulty has satisfied people's demand.
Summary of the invention:
The object of the present invention is to provide that a kind of insulated enclosure is good, high temperature resistant, the sealed insulation electrode lead-out rod of the silicon tetrachloride radiant electric heater that is applicable to explosion-proof occasion.
To achieve these goals, the present invention proposes following technical scheme realization:
The sealed insulation electrode lead-out rod of silicon tetrachloride radiant electric heater is comprised of end sealing, metal tube, copper rod, stainless steel bar, magnesia powder; It is characterized in that: copper rod and stainless steel bar are welded as a whole, and form electrode and draw rod; Electrode draws rod and places metal tube, and wherein for an end of stainless steel bar extends metal tube, electrode draws between rod and inner wall of metal tube fills magnesia powder, and metal tube is installed end sealing by copper rod one end; The sealed insulation electrode lead-out rod is rolling through rolling tube equipment, metal tube and furnace wall welding, stainless steel bar end and the interior heating wire welding of stove of extending metal tube.
The position of described metal tube and furnace wall welding, the electrode in its metal tube draws rod and consists of stainless steel bar.
Described magnesia powder can bear 5bar air pressure at the sealed insulation electrode lead-out rod after rolling.
The soluble technical problem of the present invention is:
(1) patent of the present invention is drawn rod with electrode and is placed metal tube, and draw between rod and inner wall of metal tube at electrode and to fill resistant to elevated temperatures magnesia powder as insulating material, after rolling tube equipment is rolling, so that magnesia powder density is larger, can bear 5bar air pressure, the sealed insulation performance is better, is suitable for the explosion-proof occasion of whole nitrogen filled protection; Heating wire welds in metal tube and the furnace wall welding, and the electrode in its metal tube of position of welding draws rod and consist of stainless steel bar, the stainless steel bar end of extending metal tube and stove, can bear furnace high-temperature so that electrode draws rod.
(2) patent electrode of the present invention draw the rod be welded as a whole by copper rod and stainless steel bar, stainless steel bar has guaranteed that electrode draws rod and can be used in the high temperature occasion, and copper rod has good conductivity, can avoid occuring owing to the situation of drawing excellent over-heat inside that ampacity causes greatly.
Description of drawings:
Fig. 1 is patent cutaway view of the present invention.
Embodiment:
As shown in the figure, the sealed insulation electrode lead-out rod of silicon tetrachloride radiant electric heater is comprised of end sealing 1, metal tube 2, copper rod 3, stainless steel bar 4, magnesia powder 5; Copper rod 3 is welded as a whole with stainless steel bar 4, forms electrode and draws rod, and stainless steel bar 4 has guaranteed that electrode draws rod and can be used in the high temperature occasion, and copper rod 3 has good conductivity, can avoid drawing the overheated situation generation of rod owing to the electrode that ampacity causes greatly; Electrode draws rod and places metal tube 2, and wherein for an end of stainless steel bar 4 extends metal tube 2, electrode draws fills resistant to elevated temperatures magnesia powder 5 as insulating material between rod and metal tube 2 inwalls, and metal tube 2 is by copper rod 3 one ends installation end sealing 1; The sealed insulation electrode lead-out rod is rolling through rolling tube equipment, after rolling tube equipment is rolling, so that magnesia powder 5 density are larger, can bear 5bar air pressure, and the sealed insulation performance is better, is suitable for the explosion-proof occasion of whole nitrogen filled protection; Metal tube 2 and furnace wall 6 welding, the position of metal tube 2 and furnace wall 6 welding, the electrodes in its metal tube 2 draw rod and consist of stainless steel bar 4, extend stainless steel bar 4 ends and interior heating wire 7 welding of stove of metal tube 2, can bear furnace high-temperature so that electrode draws rod.
Patent of the present invention have insulated enclosure good, high temperature resistant, be applicable to the advantages such as explosion-proof occasion, have great promotional value.
