Description
Technical field：
It the utility model is related to technical field of crystal growth, and in particular to a kind of oxyhydrogen flame for circular quartz channel closure
Nozzle.
Background technology:
The crystal such as vertical gradient temperature freezing method (VGF) growth GaAs, indium phosphide are used, it is necessary to be provided for crystal growth
Crystal, is generally sealed in quartz tubular container by stable high vacuum environment.Currently used quartz container by quartz ampoule and
Cap two parts composition is held, the air in quartz container is pumped using vacuum equipments such as molecular pumps and reaches true needed for crystal growth
After Altitude, quartz ampoule and end cap are sealed by way of welding, to ensure in the complete period of crystal growth, quartz holds
Vacuum environment in device meets crystal growth demand.
Utility model content:
The utility model develops a kind of oxyhydrogen flame nozzle for circular quartz channel closure, and the nozzle is in quartz ampoule and end
Hydrogen-oxygen mixing is abundant when cap welds, burning is complete, uniformity of temperature profile, available for the sealing of quartz ampoule under vacuum or normal pressure, knot
Structure is simple, convenient preferably to go, easy to operate.
The invention for solving the technical problem can reach by following technical solution:Hydrogen-oxygen for circular quartz channel closure
Flame nozzle includes oxyhydrogen mixing tube, and oxyhydrogen mixing tube is circular arc, and oxyhydrogen mixing tube is connected with oxygen catheter, oxygen
Conduit is bend pipe, and oxyhydrogen mixing tube is connected with hydrogen conduit, and hydrogen conduit is straight tube, the opposite side cloth of oxyhydrogen mixing tube
10-15 flame-thrower nozzle is equipped with, flame-thrower nozzle is connected by connecting tube with oxyhydrogen mixing tube.
The material of oxyhydrogen mixing tube, connecting tube, nozzle, hydrogen conduit and oxygen catheter in such scheme is copper.
The both ends seamless seal of oxyhydrogen mixing tube.The link position of hydrogen conduit and oxyhydrogen mixing tube is located in oxyhydrogen mixing tube
Point.Hydrogen conduit and distance of the link position of oxyhydrogen mixing tube away from oxyhydrogen mixing tube one end are oxyhydrogen mixing tube overall length
1/5th at.
The utility model can have the advantages that compared with above-mentioned background technology:
Brief description of the drawings:
Accompanying drawing 1 is structural representation of the present utility model.
In figure:1st, oxyhydrogen mixing tube, 2, connecting tube, 3, nozzle, 4, hydrogen conduit, 5, oxygen catheter.
Embodiment:
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, the oxyhydrogen flame nozzle for being used for circular quartz channel closure includes oxyhydrogen mixing tube 1, oxyhydrogen
Mixing tube 1 is circular arc because the sealing for circular quartz pipe, the oxyhydrogen mixing tube 1 of circular arc for ease of quartz ampoule by
It is hot uniform.Oxyhydrogen mixing tube 1 is connected with oxygen catheter 5, and oxygen catheter 5 is bend pipe, and the oxygen catheter 5 of this shape can subtract
The production well capacity of slow oxygen.Oxyhydrogen mixing tube 1 is connected with hydrogen conduit 4, and hydrogen conduit 4 is straight tube, oxyhydrogen mixing tube 1
Opposite side be evenly arranged 10 or 12 flame-thrower nozzles 3, flame-thrower nozzle 3 is relative with oxygen catheter 5 and hydrogen conduit 4 to be set
Put, flame-thrower nozzle 3 is connected by connecting tube 2 with oxyhydrogen mixing tube 1.Oxyhydrogen mixing tube 1, connecting tube 2, nozzle 3, hydrogen
The material of conduit 4 and oxygen catheter 5 is copper.The both ends seamless seal of oxyhydrogen mixing tube 1.
Uniform for the ease of Hydrogen distribution, hydrogen conduit 4 is located at oxyhydrogen with the link position of oxyhydrogen mixing tube 1 and mixed
The midpoint of pipe 1.
Hydrogen conduit 4 mixes with distance of the link position of oxyhydrogen mixing tube 1 away from the one end of oxyhydrogen mixing tube 1 for oxyhydrogen
At close the overall length of pipe 1 1/5th.The setting effect one of the position of hydrogen conduit 4 is supplied from one end, and effect two is to strengthen
The intensity of whole device.
