Abstract
The utility model relates to a tungsten-halogen electric heating tube, which is composed of a tungsten filament, a molybdenum piece, a molybdenum rod, a steel head, a ceramic head and a quartz tube. The tungsten filament is an electric heating filament, and the two ends is firmly connected with the leading wire molybdenum rod through the molybdenum piece; the two ends of the quartz tube hot-presses and seals the molybdenum piece and part of the molybdenum rod; the other end of the molybdenum rod is fixedly connected with the steel head; the ceramic head is covered on the connecting part of the quartz tube and the steel head; the inside of the ceramic head is filled with solder; after solidified, the solder is mutually pasted firmly; the steel head penetrates out of the ceramic head to become an electrode of the electric heating tube. After the inside of the electric heating tube is evacuated, halogen or halide gas is filled in so that tungsten-halogen cycle is carried out in the working process of the tungsten filament and the halogen. The electric heating tube has low energy consumption, high thermal efficiency and a long service life.
Description
The utility model relates to a kind of electroheat equipment, particularly a kind of halogen tungsten electrothermal tube.
Traditional electrothermal tube, its heating wire generally adopt nickel filament or the coiling of siderochrome nickel wire to form.Be that power consumption is big and the life-span is short outside the deficiency of this electrothermal tube.
The purpose of this utility model is a kind of thermal efficiency height of design, the electrothermal tube of long service life.
The utility model halogen tungsten electrothermal tube comprises tungsten filament, molybdenum sheet, molybdenum rod, it is characterized in that being made of transparent quartz tube, steel toe and porcelain head.Tungsten filament coiling shape and suprasil tube shape adapt, its two ends respectively are connected by a molybdenum sheet and molybdenum rod, molybdenum rod stretches out the quartz ampoule two ends, molybdenum sheet, molybdenum rod and the hot sealing of quartz ampoule end, and the molybdenum rod part of stretching out the quartz ampoule two ends conducts with steel toe respectively and is connected, porcelain head is a hollow cap, cover on quartz ampoule and steel toe connecting portion, the gap is filled with scolder, and steel toe stretches out porcelain head, become the electrothermal tube electrode, vacuumize the back in the transparent quartz tube and fill halogen or halide gas.
Halogen tungsten electrothermal tube with said structure characteristics, its molybdenum sheet is used to connect transition, tungsten filament reliably is connected with the extraction electrode molybdenum rod, molybdenum rod and steel toe firm welding had both guaranteed good conducting, and had guaranteed that again electrothermal tube has enough intensity, hot sealing between quartz ampoule and molybdenum sheet, the molybdenum rod, make molybdenum rod, molybdenum sheet and air insulated, can prolong its useful life, thereby also prolonged the electrothermal tube life-span.
This halogen tungsten electrothermal tube also will insert gas extraction system and vacuumize after encapsulation, charge into halogen or halogen compounds gas under high vacuum.
The halogen tungsten electrothermal tube that is obtained by said structure and means has that power consumption is low, and thermal radiation is big, the characteristics that thermal efficiency is high, and this electrothermal tube carries out the halogen tungsten circulation in the course of the work, has prolonged the useful life of electrothermal tube greatly.
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 halogen tungsten electrothermal tube two-end structure schematic diagram
This halogen tungsten electrothermal tube is by tungsten filament 1, transparent quartz tube 2, molybdenum sheet 3, molybdenum rod 5, porcelain head 4 and steel toe 6 constitute, tungsten filament 1 coiling shape and transparent quartz tube 2 shapes adapt, a molybdenum sheet 3 is respectively welded at its two ends, molybdenum rod 5 one ends are welded on the molybdenum sheet 3, the other end welds in the slotted eye on steel toe 6, the two ends of transparent quartz tube 4 and molybdenum sheet 3, the portion of hot means of press seals of molybdenum rod 4, porcelain head 4 is a hollow cap, cover on the coupling part of quartz ampoule and steel toe, the one end has the hole, the diameter of aperture and steel toe 6 adapts, other end fluting, quartz ampoule end shape with hot sealing, size matches, and should insert scolder in the space between porcelain head and quartz ampoule and the steel toe, makes each other to cement after scolder solidifies.
Finish the halogen tungsten electrothermal tube after said structure assembles, also need in quartz ampoule, vacuumize, charge into halogen or halide gas then.
The utility model can be made difformity according to different needs, and for example, electrothermal tube should be made ring-type when being used for the electric furnace heater.
