Specific embodiment
The gas refining melting furnace for being used for continuous production cylinder of quartz glass is made of furnace body 1, and burner hearth 2, furnace are provided in furnace body 1
Thorax 2 be cover it is bowl-shape, be at the top of burner hearth 2 it is arc-shaped, burner putting hole 3 is provided on the furnace body 1 at the top of burner hearth 2, for placing
Burner, and 2500 degree or more of the high temperature melting quartz powder materials generated using burner.
Former 4 is fixedly installed in the lower port of burner hearth 2, the circumference and 2 inner wall of burner hearth of former 4 are tightly connected.At
Type device 4 is made of mounting ring 5, shaping column 6 and support rod 7, the support rod that the centre of mounting ring 5 is arranged by right-angled intersection
7 are equipped with shaping column 6.The inner hole of mounting ring 5 is in horn-like, to play a guiding role to the quartz powder materials of fusing, thus in weight
It flows downward under power.It is sphere curved surface at the top of shaping column 6.It is arc at the top of support rod 7, to make the silica flour of fusing at work
Expect to flow into the inner hole of mounting ring 5, is arranged by shaping column 6 in the centre of mounting ring 5, was forming quartz powder materials
It can not be full of the inner hole of mounting ring 5 in journey, to form the hole at center, achieve the purpose that produce cylinder of quartz glass.
4 bottom end of former is provided with basic target 8；It is arranged fluted 9 on basic target 8.The size and 6 ruler of shaping column of groove 9
It is very little to coincide, so that 6 lower end of shaping column of former 4 is inserted into the upper end of basic target 8.
The periphery of furnace body 1 is disposed with thermal insulation inner-wall 10, insulating 11 and heat preserving exterior wall 12,10 He of thermal insulation inner-wall
Heat preserving exterior wall 12 is that insulating 11 provides (filling basis) support, and insulating 11 can effectively prevent heat exchange pattern
Heat dissipation, thermal insulation inner-wall 10 is used to increase the intensity and refractory ability of furnace body 1.
Be symmetrically arranged with air duct 13 on the burner hearth 2 of the top of former 4, the one end in air duct 13 through furnace body 1, thermal insulation inner-wall 10,
Insulating 11 extends to 12 outer end of heat preserving exterior wall, and air duct 13 is used to discharge the exhaust gas that burning generates, and increases in burner hearth 2
Gas flow capability.
When the gas refines melting furnace work, basic target 8 of first boosting makes the groove 9 and former 4 at basic 8 top of target
Shaping column 6 is bonded completely, that is, is inserted into shaping column 6 in groove 9, basic target 8 forms the inner hole bottom end of mounting ring 5 as a result,
It blocks；To prevent the quartz powder materials outflow of fusing at work.
It is above-mentioned be ready to complete after, light oxygen-hydrogen burner generate thermal-flame, quartz powder materials are primary melting, the stone of fusing
English powder extends flowing at high temperature, and the guiding role through support rod 7 and mounting ring 5 is flowed into the inner hole of mounting ring 5, this
In the process, since shaping column 6 is inserted into groove 9, basic target 8 forms the inner hole bottom end of mounting ring 5 and blocks, and flows into mounting ring
The quartz powder materials of fusing in 5 inner holes are constantly collected in the inner hole of mounting ring 5；When the quartz powder materials of the fusing in inner hole are filled
After the inner hole of full former 4, basic target 8 starts slowly to move downward, and during this, the quartz powder materials of fusing leave mounting ring
After 5 inner holes, temperature i.e. decline rapidly, the quartz powder materials of temperature decline are frozen into silica glass ingot, wherein since shaping column 6 accounts for
According to the middle position of 5 inner hole of mounting ring, the silica glass ingot center of solidification will form hole, reach the mesh of production cylinder of quartz glass
, basic target 8 constantly moves downward, and can gradually continuously produce cylinder of quartz glass.
The gas refines melting furnace in process of production, the burn-off rate phase of the speed that basic target 8 moves downward and quartz powder materials
Deng the quartz powder materials moment of i.e. fusing in 5 inner hole of mounting ring remains full of state；Guarantee that cylinder of quartz glass (ingot) produces with this
Continuity.The gas refines melting furnace compared with the gas of continuous silica glass ingot refines quartzy furnace, has the characteristics that one-pass molding, makes
During standby cylinder of quartz glass (ingot), it can be made directly to be in cartridge type by former 4, be not necessarily to silica glass ingot after molding two
Secondary digging process, and keep the quartz powder materials of melting more preferable in the quartzy furnace internal mobility of gas refining by air duct, there is better bubble
The defects of excluding effect and less color spot, calculus, allows it to be preferably applied to aerospace, optics, optical fiber and partly lead
Body field meets private and science and techniques of defence needs.
