Abstract
The utility model relates to a molybdenum electrode for heating glass metal. The solved technical problem is as follows: the provided molybdenum electrode has the characteristics that water cooling is not needed, and oxidization is hard under a high-temperature state. In the technical scheme, the molybdenum electrode without water cooling comprises a molybdenum electrode which is horizontally arranged in a furnace wall, wherein the front part of the molybdenum electrode is extended into glass metal in a glass furnace for heating; the molybdenum electrode without water cooling is characterized in that the rear end of the molybdenum electrode is electrically connected with an electricity leading rod through a nickel sleeve, the molybdenum electrode is connected with the nickel sleeve by a threaded structure, and the nickel sleeve is welded with the electricity leading rod.
Description
Technical field
The utility model relates to the heating unit in the glass manufacturing area, specifically is the molybdenum electrode of heating glass liquid.
Background technology
Molybdenum electrode is the heating unit that glass furnace adopts.Conventional molybdenum electrode all need use the watercooling jacket water flowing to cool off because of high temperature oxidation very easily, per hour need consume water coolant 8-20L; And the employing water quench, can cause the temperature of glass liquid near the kiln pool wall sharply to descend, influence clarification, the homogenizing of the interior glass metal of kiln, the production precision of Glass tubing there is certain influence, can increase energy consumption again; If accident occurring cuts off the water supply, the water in the water jacket volatilizees totally soon in addition, and water jacket and electrode temperature raise rapidly; During water flowing,, influence the normal use of electrode once more because quick cooling very easily causes water jacket to burst.
The utility model content
The technical problems to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of molybdenum electrode is provided, and this molybdenum electrode should have the characteristics that the water-cooled of not needing, the condition of high temperature are difficult for oxidation, to realize safety in production.
The technical scheme that the utility model provides is: no water-cooled molybdenum electrode comprises being horizontally fixed in the furnace wall and the molybdenum electrode that heats in the glass metal in the glass furnace is stretched in its front portion; The rear end that it is characterized in that described molybdenum electrode by nickel cover with draw torch and be electrically connected.
Described molybdenum electrode is connected by helicitic texture with the nickel cover.
Described nickel overlaps and draws torch and is welded to connect.
Principle of work of the present utility model is: molybdenum electrode in the middle of air 200 ℃ will oxidation, temperature high rate of oxidation more is just fast more.Molybdenum electrode and stainless steel draw increase a nickel cover between the torch after, because the fusing point of nickel is 1455 degree, and the alkali-resistivity and the corrosion resistance of nickel are stronger, like this molybdenum electrode are immersed in the glass metal fully, just do not contact with air and can effectively prevent the molybdenum electrode oxidation.
The beneficial effects of the utility model are: do not contact with air owing to molybdenum electrode is immersed in the glass metal fully, thereby can prevent the molybdenum electrode oxidation effectively, obviously prolong work-ing life; So just need not adopt chilled water unit.This molybdenum electrode device that does not need water cooling, is difficult for oxidation is installed easily, and is easy to maintenance, can also significantly reduce energy consumption.
Description of drawings
Fig. 1 is a mounting structure synoptic diagram of the present utility model.
Fig. 2 is the structural representation of the molybdenum electrode of existing adapted chilled water unit.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 2: conventional molybdenum electrode 9 is horizontally fixed in the watercooling jacket 7 on the furnace wall 3, and its front portion is stretched in the glass metal 1 in the glass furnace and heated; Water coolant enters watercooling jacket from entrance of cooling water 7-1, derives from cooling water outlet 7-2 again after the heat absorption.Obviously, complex structure, energy consumption is bigger.
The utility model comprises three integral parts: draw torch 4 (recommending to draw torch with stainless steel), nickel cover 5, molybdenum electrode 2; Draw torch and be used to connect bronze medal, cable; The internal thread of nickel cover is connected with the outside screw of molybdenum electrode; Molybdenum electrode is inserted fully and is used for heating glass liquid in the glass metal.Because complete and air insulated are so molybdenum electrode 2 is not easy oxidation.
Claims (3)
1. do not have the water-cooled molybdenum electrode, comprise being horizontally fixed in the furnace wall (3) and the molybdenum electrode (2) that heats in the glass metal (1) in the glass furnace is stretched in its front portion; The rear end that it is characterized in that described molybdenum electrode by a nickel cover (5) with draw torch (4) and be electrically connected.
