Embodiment 1

[0049] step one:

[0050] Soda-lime-silica glass frit is melted and water-quenched, spread on a plate and placed in an oven to dry at 100°C for 5 hours. The dried water-quenched frit is crushed with a crusher. After the crushing is completed, it is Pass through a 10-mesh sieve and a 30-mesh sieve in turn, leaving a water-hardened glass frit of an intermediate size;

[0051] Step two:

[0052] Beading using a beading device:

[0053] First, turn on the natural gas pipeline switch by controlling the temperature indicator, and then use an open flame to ignite the natural gas, then control the temperature indicator to open the oxygen pipeline switch to supply oxygen, and at the same time manually open the compressed air switch to supply compressed air. Adjust the flow of air, natural gas, and oxygen by the degree of closure of the switch until the length of the flame just reaches the top cover. After the temperature of the furnace body reaches 900°C, keep it warm for 30 minutes...

Embodiment 2

[0057] step one:

[0058] After the glass frit of borosilicate glass is melted and water-quenched, spread it on a plate and put it in an oven to dry at 100°C for 5 hours. Use a crusher to break the dried water-quenched glass frit. After the crushing is completed, put It passes through a 10-mesh sieve and a 30-mesh sieve in turn, leaving a water-hardened glass frit of an intermediate size;

[0059] Step two:

[0060] Beading using a beading device:

[0061] First, turn on the natural gas pipeline switch by controlling the temperature indicator, and then use an open flame to ignite the natural gas, then control the temperature indicator to open the oxygen pipeline switch to supply oxygen, and at the same time manually open the compressed air switch to supply compressed air. Adjust the flow of air, natural gas, and oxygen by the degree of closure of the switch until the length of the flame just reaches the top cover. After the temperature of the furnace body 2 reaches 950°C, k...

Embodiment 3

[0065] step one:

[0066] After the glass frit of high-alumina glass is melted and water-quenched, spread it on a plate and put it in an oven to dry at 100°C for 5 hours. Use a crusher to crush the dried water-quenched frit. After the crushing is completed, it is sequentially Pass through a 10-mesh sieve and a 30-mesh sieve, leaving a water-hardened glass frit of an intermediate size;

[0067] Step two:

[0068] Beading using a beading device:

[0069] First, turn on the natural gas pipeline switch by controlling the temperature indicator, and then use an open flame to ignite the natural gas, then control the temperature indicator to open the oxygen pipeline switch to supply oxygen, and at the same time manually open the compressed air switch to supply compressed air. Adjust the flow of air, natural gas, and oxygen by the degree of closure of the switch until the length of the flame just reaches the top cover. After the temperature of the furnace body 2 reaches 1000°C, keep...

Abstract

The invention discloses a preparation method and a production device of large-particle spherical glass, a gas-material co-spraying balling process is adopted, in the balling process of the glass, the glass does not make contact with other materials, the surface is smooth, and secondary treatment and cleaning are not needed. And the outlet of a high-temperature furnace adopts a trumpet-shaped flame structure, so that the static pressure of a high-temperature section is increased on the basis of ensuring the low-temperature kinetic energy of the frit, and the high-temperature separation of gas and solid glass balls is strengthened while the frit is fully heated. Oxygen-enriched combustion flames are adopted, so that the rigidity of the flames is improved, the atmosphere in the combustion process is ensured, and the color of the glass is stable. And a gas and furnace temperature linkage control technology is adopted, so that the product quality is ensured, and the production cost is reduced. A furnace body structure step-by-step heat preservation technology is adopted, so that the high temperature is not reduced, the low temperature is not increased, meanwhile, the cost is saved, and the production efficiency is improved. And the top cover is cooled by water, so that the service life of the equipment is fully prolonged while environmental protection is realized.

Description

technical field [0001] The invention relates to a preparation method and device of spherical glass, in particular to a preparation method and production device of large particle spherical glass. Background technique [0002] Spherical glass material is a spherical material with a certain particle size and a complete and smooth surface. It is a new type of inorganic silicate material. The emergence of spherical glass materials has a history of nearly a hundred years. The earliest large-scale production began in the 1940s by the Porter Industries Co., Ltd. of the United States. Spherical glass materials have many unique properties, such as good roundness, uniformity, transparency, hardness, light reflection characteristics and excellent chemical stability, etc. At present, spherical glass materials have already become indispensable materials in daily life , and are widely used in aerospace, marine, electronics, medicine, highways, automobile identification, chemical industry ...
