Description

Technical Field

[0001] The utility model relates to the technical field of glass microsphere spheroidization, in particular to a high-refractive-index glass microsphere spheroidization device. Background Art

[0002] A burner for powder spheroidization is a device that can continuously and stably burn, heating the powder until it melts and then cooling it into spheres. Burners are generally divided into oil burners, gas burners, and other types. They are used in a wide range of applications and are required wherever fuel combustion is required to heat materials or react. Although the burners currently on the market all have the basic characteristics of stable combustion, high thermal efficiency, and safe use, for the high-refractive index glass microsphere industry, the burners currently on the market cannot well meet its special needs: concentrated firepower, large outer flames with strong rigidity, and the ability to restrain the glass powder throughout the flame stroke to ensure that the powder remains at high temperature for a long time, fully melts, and does not escape from the upper edge of the flame to form raw materials.

[0003] However, the outer flame of the burner currently on the market is not rigid enough, the temperature of the working area is low, the binding force on the powder sprayed into it is weak, and the powder is easy to escape from the middle, so there is a need for improvement. Summary of the Invention

[0004] The utility model aims to solve the defects of the prior art such as insufficient rigidity of the outer flame and low temperature in the working area, and provides a new high-refractive-index glass microsphere spheroidizing device.

[0005] In order to solve the above technical problems, the present invention is implemented through the following technical solutions:

[0006] A high-refractive-index glass microsphere spheroidization device, comprising a gas proportioning and mixing device, a powder feeding device and a self-angle burner, the gas proportioning and mixing device comprising a gas solenoid valve, a combustion-supporting solenoid valve, a gas flow meter, a combustion-supporting gas flow meter, a gas mixer, a gas pipeline, a combustion-supporting gas pipeline, the powder feeding device comprising a ball valve, a feeding flow meter, a storage tank, a feeder, a feeding nozzle, the self-angle burner comprising an air intake pipe, a shell, an outer porous plate, and an inner homogenizing plate, the gas pipeline being sequentially connected to the gas solenoid valve and the gas flow meter and then communicating with the gas mixer, the combustion-supporting gas pipeline being sequentially connected to the The combustion-supporting solenoid valve and the combustion-supporting gas flow meter are connected and communicated with the gas mixer. The other end of the gas mixer is communicated with the air intake pipe. The feed nozzle is connected with the ball valve and the feed flow meter. The storage tank is communicated with the feed nozzle by means of the feeder. The mouth of the feed nozzle is located below the outer porous plate. The air intake pipe is communicated with the shell. The outer porous plate and the inner homogenizing plate are fixed on the shell. The outer porous plate is composed of two intersecting planes. The inner homogenizing plate is composed of two intersecting planes. The outer porous plate is parallel to the inner homogenizing plate.

[0007] The combination of a gas proportioning and mixing device, a powder feeding device, and a self-angled burner ensures uniform spheroidization of high-refractive index glass microspheres by precisely controlling the ratio of gas to combustion-supporting gas, as well as the amount of powder fed. This improves product quality and production efficiency. The design of the gas and combustion-supporting gas pipelines allows for precise control of the gas and combustion-supporting gas flow rates, ensuring the stability and efficiency of the combustion process, thereby improving the spheroidization quality of the glass microspheres. In the connection method between the feed nozzle and the storage tank, the powder in the storage tank is conveyed to the feed nozzle via a feeder, achieving a continuous and stable powder supply and avoiding fluctuations in product quality caused by unstable powder supply. The angled design of the outer porous plate and the inner homogenizing plate facilitates uniform mixing of the gas and combustion-supporting gas, as well as uniform heating of the powder, thereby improving the spheroidization effect of the glass microspheres.

[0008] Preferably, in the above-mentioned high-refractive-index glass microsphere spheroidizing device, the orifice of the feed nozzle is 10 to 30 mm lower than the outer porous plate.

[0009] Setting the nozzle of the feed nozzle 10 to 30 mm lower than the outer porous plate can ensure that the powder is fully mixed with the gas when entering the burner, and effectively prevent the powder from sticking to the porous plate and causing clogging of the porous plate, thereby improving combustion efficiency and spheroidization quality.

[0010] Preferably, in the above-mentioned high-refractive-index glass microsphere spheroidizing device, the number of the inner-layer equalizing plates is at least one, and the inner-layer equalizing plates are parallel to each other.

[0011] The design of at least one inner homogenizing plate and the parallel arrangement of the inner homogenizing plates help to improve the mixing uniformity of the fuel gas and the combustion-supporting gas, thereby improving the spheroidization quality of the glass microspheres.

[0012] Preferably, in the above-mentioned high-refractive-index glass microsphere spheroidization device, an outer porous plate is provided with outer through holes and inner through holes, and the diameter of the outer through holes is larger than that of the inner through holes.

[0013] Preferably, in the above-mentioned high-refractive-index glass microbead spheroidization device, the outer through-hole is arranged obliquely, and the lower end of the outer through-hole is inclined toward the center of the outer porous plate.

[0014] The design of larger outer holes than the inner holes, along with their tilted placement, helps improve gas flow efficiency and enhance the flame's binding force on the powder, reducing powder escape from the flame, promoting uniform heating of the powder, and enhancing spheroidization. When the spheroidization process requires larger particle size, the outer perforated plate can be tilted inward by 1-4°. For general product spheroidization, only the innermost rows of holes can be tilted inward by 1-4°.

[0015] Preferably, in the above-mentioned high-refractive-index glass microbead spheroidization device, the number of the powder feeding devices is 2 groups.

[0016] The installation of two powder feeders improves production efficiency while ensuring a stable powder supply and avoiding production interruptions caused by failure of a single component. The dual feeder not only increases production capacity but, when combined with a self-angled burner, allows for controlled collision and fusion of smaller powders during the spheroidization process, increasing their size.

[0017] Preferably, in the above-mentioned high refractive index glass microsphere spheroidization device, the feed gas is oxygen.

[0018] Using oxygen as the feed gas can improve the combustion efficiency, thereby improving the spheroidization speed and quality of the glass microspheres.

[0019] Preferably, in the above-mentioned high-refractive-index glass microbead spheroidization device, the direction of the nozzle of the feed nozzle is consistent with the length direction of the outer porous plate.

[0020] Aligning the nozzle of the feed nozzle with the length direction of the outer porous plate can ensure that the powder is aligned with the flow direction of the gas when entering the burner, thereby improving combustion efficiency and spheroidization quality.
