Description
Technical field
The present invention relates to a kind of spray guns for being used to prepare high-refraction glass bead, belong to high refractive index glass micro pearl manufacture and set
Standby technical field.
Background technology
The traditional preparation methods of high refractive index glass micro pearl can be divided into two major class of melt method and powder method.It generally adopts both at home and abroad
High refractive index glass micro pearl is prepared with powder method, the cullet powder for meeting granularity requirements that will have been sieved adds in pulverizing jet or height
Beading is heat-treated in warm stove, and because the production technology of blowing process has the advantages that technically simple, beading is efficient, at low cost, because
This extensive use during powder method prepares high refractive index glass micro pearl, by obtained glass dust according to certain granularity requirements
After carrying out ball milling sieving, a certain amount of graphite powder is mixed as interleaving agent, the interior heating of feeding high temperature furnace after mixing melts, because
This prepares glass microballoon using blowing process must then use spray gun device, and Yeong-Shiau equality people exists《TiO2-BaO-SiO2 systems height is rolled over
Penetrate the development of rate glass microballoon》The spray gun device of one described in the text, if there are one air feed mouth, glass dust feed inlet, acetylene
Air is sent into spray gun by gas feed inlet with air compressor, meanwhile, make to generate negative pressure in the device of Sheng glass dust, by device
In the powder sucking intermediate air jet pipe that flies upward, when air with powder reaches nozzle, with fuel gas acetylene in gas phase
Chance is lighted, and so as to which nozzle is everywhere in high temperature, under the impact of air-flow, powder injects beading stove with high speed from spray gun, makes glass
Powder is uniformly dispersed and is melted in combustion zone, due to the effect balling-up of surface tension, beading after the cooling that falls into the water.Using above-mentioned
Spray gun device, it is poor to be susceptible to the microballon roundness prepared, is sometimes prone to the defects of small tail, wire drawing cotton occur, and
The glass microballoon surface produced is stained with graphite powder, it is more difficult to which washes clean is also easy to produce the glass microballoon of devitrification, and production efficiency is not
It is high.
Invention content
For more than the deficiencies in the prior art, the technical problems to be solved by the invention are that providing one kind is used to prepare height
The spray gun of refraction glass bead, it is intended to solve the problems such as microballon roundness prepared in existing lance driving device is poor.
In view of the above shortcomings of the prior art, the present invention proposes a kind of spray gun for being used to prepare high-refraction glass bead,
Including：
One mixing chamber has three upper chamber, middle chamber and lower chambers parts；

Further, the resistance for fuel gas flow in reduction pipeline, center and the output of the gas inlet channel
The center of pipeline is in same horizontal line, so as to reduce flowing combustion gas and the collision of tube wall.
Further, to reduce the resistance of powder and combustion-supporting gas in Bottomhole pressure, the output channel and the mixing chamber
The angle of chamber interior walls is 35~50 °.
Further, can be equipped with to ensure there is a sufficient raw material in pipeline, on the output channel the second raw material into
Pipe material.
Further, in order to ensure that raw material and combustion gas, combustion-supporting gas maintain higher speed, and and beading stove after spray gun
The speed of beading matches, and the internal diameter of the feedstock pipeline inner cavity is 20~30mm, the combustion-supporting gas inlet channel inner cavity
Internal diameter for 3~20mm, the internal diameter of the inner cavity of the gas inlet channel is 3~20mm, and the internal diameter of the output channel is 15
~25mm, length are 20~30cm.
Further, to ensure at the material inlet, continual supply at the second material inlet, setting
There is the feed well for matching with it and using.
The beneficial effects of the present invention are：The spray gun provided by the present invention for being used to prepare high-refraction glass bead, can fill
Divide and be uniformly mixed combustion-supporting gas, combustion gas with base glass powder, burning is sprayed into so as to which glass powder be driven to generate certain speed
In stove, requirement during meeting glass powder balling-up to temperature, length and speed so that the high-refraction glass bead produced
Roundness is preferable；Meanwhile the spray gun provided by the present invention for being used to prepare high-refraction glass bead, production capacity for 80~
200 kilograms/h, significantly larger than existing apparatus, substantially increase production efficiency, shorten the production time；Finally, present apparatus structure
It is simple and convenient to operate and of low cost, it is easy to spread.
