Description
Technical field:
The present invention relates to a kind of manufacture method of quartz glass cotton and be used for the device of this manufacture method, belong to the manufacturing technology field of quartz glass fibre.
Background technology:
At present, the production of simple glass cotton has two kinds of methods, centrifuging and flame spraying, centrifuging are that raw material is melted in crucible or tank furnace, and the glass metal that fusing is good flows out through the bushing of material road end, enter sedimentator, under supercentrifuge drives, throw away the glass thread by the sidewall of sedimentator, the glass thread is under the effect of combustion chamber high temperature high-speed flame, become cellucotton by further drawing-off, by condensers it is gathered into cotton again.Flame ejection method also is that raw material is melted in crucible, and the glass metal that fusing is good flows out through bushing and forms one silk, and this is delivered in the flame of combustion chamber ejection under the traction of glue rod, forms cotton fibre, by condensers it is gathered into cotton again.But can not produce quartz glass cotton with the method for producing the simple glass cotton, its reason is that the melt temperature of silica glass need be controlled at 1800～2200 ℃, melt temperature than simple glass fiber exceeds more than 500 ℃, therefore, produce quartz glass cotton with two kinds of methods of above-mentioned production simple glass cotton and have difficulty greatly.Existing method of producing quartz glass cotton is to adopt the rod method production that blows floating, be about to quartz pushrod and quartz pushrod blown out quartz glass cotton after with 1 800～2200 ℃ high temperature and high speed flame fusing, but the quartz glass cotton filament diameter thickness that this method is produced is inhomogeneous, influence result of use, and production efficiency is extremely low.
Summary of the invention:
The objective of the invention is to: a kind of method that burner and one group of spraying burner carry out two-stage melt production quartz glass cotton of mixing in adopting a group is provided, the silica wool filament diameter thickness that the production method of the existing silica wool of solution is produced is inhomogeneous, production efficiency is low, the problem of inconvenient operation; And the supporting isolated plant of production method for this reason.
The present invention realizes above-mentioned purpose by the following technical solutions:
The manufacture method of this quartz glass cotton realizes that as follows it comprises following five different steps:

The 3rd step: open motor power, send the linear velocity of excellent device to transfer to 15mm/min-50mm/min the Precision Stepless speed change, making quartz pushrod is 2.4 seconds-8 seconds through the fusion time of interior mixed burner flame; Linear velocity with the pair roller fiber feeder transfers to 1700mm/min-2600mm/min again.
The 4th step: the quartz glass bar that will be melted at the burner port of interior mixed burner draws with the quartz glass bar point and draws wire
0.15mm-
0.25mm after, send in the pair roller fiber feeder.
The 5th step: the silk that the pair roller fiber feeder is pulled out is by behind the artificial introducing pressure pin, accurately is incorporated into the burner port of spraying burner through location boundling plate, is melted the back and sprayed by the high temperature and high speed air-flow of spraying burner and form quartz glass cotton, and send in the condensers.
The 6th step: take out the quartz glass cotton of sending in the condensers and detect qualified continuation production; If defective, finely tune the linear velocity that the Precision Stepless speed change that quartz glass bar is housed is sent excellent device again according to detected result again, till the linear velocity standard that reached for the 3rd step.
The 7th step: when containing the combustion jet air-flow process condensers of quartz glass cotton, condensers is collected in quartz glass cotton together, and every 20-30min that crosses is again with the quartz glass cotton collecting packing on the condensers.
The device that is used for the manufacture method of above-mentioned quartz glass cotton send excellent device by the Precision Stepless speed change, motor a, motor b, the interior burner that mixes, the pair roller fiber feeder, pressure pin, location boundling plate, spraying burner, condensers and frame constitute, it is characterized in that: the Precision Stepless speed change is housed above the frame left end send excellent device, motor a is housed below, mix burner in being equipped with above the frame right-hand member, the pair roller fiber feeder, pressure pin, location boundling plate and spraying burner, location boundling plate and the top of spraying burner are equipped with a condensers by pole, motor b are housed below the frame right-hand member.
Mix on burner and the spraying burner in described and be connected with gas line and oxygen hose respectively.
The present invention's beneficial effect compared with prior art is, mixed burner and one group of spraying burner two-stage fused method were carried out the production of quartz glass cotton in the present invention adopted one group, make quartz glass bar elder generation after the temperature of 1800-2200 ℃ flame is drawn into silk, temperature through 2000-2200 ℃ flame is melt into quartz glass cotton again, it is inhomogeneous to have solved the silica wool filament diameter thickness that the method for existing production quartz glass cotton produces, production efficiency is extremely low, and the problem of inconvenient operation.
