Description
Affiliated field
The utility model relates to a kind of device of high temperature treating high voltage mercury lamp electrode.
Background technology
Ultrahigh pressure mercury lamp belongs to a kind of desirable point-source of light, and it is photochromic abundant, and the colour temperature height is mainly used in projecting apparatus and other shadow casting technique field that little liquid crystal board high brightness is exported.The ultrahigh pressure mercury lamp utilization is filled with interior high-pressure mercury vapor discharge, the acquisition visible light source of producing of electric arc tube of mercury.The electrode that produces discharge is that tungsten is made.In the manufacturing process of tungsten electrode, need carry out high-temperature process to it, to remove the low melting point impurity in the tungsten electrode.Otherwise at when work, the ambient operating temperature height of electrode, the low melting point impurity in the tungsten electrode can have a strong impact on the discharge of electrode, and the low melting point foreign metal is evaporated on the glass bulb, makes the glass bulb blackout, influences the brightness and the useful life of lamp.
The method of existing processing tungsten electrode is that electrode is placed in the special-purpose high fever stove, and the body of heater of this special use high fever stove is the tungsten tube that multilayer tungsten sheet is rolled into, and by big current flow heats equipment tungsten tube body of heater is passed to big electric current more than the 100A then, makes tungsten tube heating up.And by heat exchange pattern with the processed electrode in the heat transferred tungsten tube.The thermaltransmission mode that this mode of heating adopts can't pass to heat inner electrode effectively, energy consumption is big, power consumption reaches 500kw, and heating time is long, and heating once needs 3-4 hour, and its heating-up temperature is the highest can only to reach 2000-2400 ℃, and its thermal effectiveness is undesirable.And owing to need to adopt expensive multilayer tungsten sheet to be rolled into the tungsten tube, also need expensive supporting big current flow heats equipment, make its cost height.Home equipment is a 30-40 contingency platform, and import is then up to 60-80 contingency platform.
Summary of the invention
The purpose of this utility model just provides a kind of device of high temperature treating high voltage mercury lamp electrode, and this device can be efficiently to heated by electrodes, intensification, the temperature height of high-temperature process, time weak point, and with the electrode brightness height after its processing, the operating time is long, and performance is good.
The utility model solves its technical problem, the technical scheme that is adopted is: a kind of device of high temperature treating high voltage mercury lamp electrode, it consists of: an end opening of horizontal cylindrical quartz glass-tube, this opening links to each other with the vacuum unit, be wound with the heater coil of coreless induction furnace on the quartz glass tube, the bottom of quartz glass tube inner chamber is placed with the bracing frame that tungsten rod is made, and the tungsten tube of tungsten filament braiding is positioned on the bracing frame.
During use, a plurality of processed electrodes closely are positioned in the tungsten tube, again the tungsten tube are placed on the bracing frame of quartz glass tube, the vacuum unit is connected, seals with the opening of quartz ampoule, quartz glass tube is vacuumized, make its air pressure inside reach 7 * 10
-2Below the Pa, to the heater coil energising of coreless induction furnace, high frequency coil is made a solid to the electrode of closely placing in tungsten tube and the tube thereof and is carried out high-frequency induction heating again.
Compared with prior art, the beneficial effects of the utility model are: because electrode is to be heated in the high-frequency induction mode in vacuum environment, its electric conversion efficiency is high, the leakage loss of energy is minimum, its energy consumption is low, power consumption is below 10kw, and heating time is short, and heating-up time and temperature fall time all shortened to about 10 minutes; And the temperature of processed electrode reaches as high as 2400-2600 ℃, and its treatment effect is good, the electrode brightness height after the wherethrough reason, and the operating time is long, and performance is good.Adopt cheap tungsten filament to be woven into the tungsten tube, replace the tungsten tube that expensive tungsten sheet rolls, and do not have expensive big current flow heats equipment, cost of the present utility model is greatly reduced, the cost of an equipment only is about 30,000 yuan.
Above-mentioned bracing frame is four pin bracing frames, and four pin bracing frames not only firmly but also convenient the making.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
