AI Technical Summary
When the existing spherulizer material sprayer sprays out silicon powder, especially silicon powder with a diameter of less than 5 microns, the diffusion is not thorough, resulting in the silicon powder being agglomerated after melting, reducing the product's pass rate, and the split design leads to the material. Inadequate contact with the flame, some of the silicon powder cannot be melted.
A material spray head for a spherical furnace is designed, including an inner shell and an outer shell. A vibrating rod and a conical stopper are provided inside the inner shell. A shrinking nozzle part is provided at the lower part of the outer shell, and a vibration rod and a stop are blocked. In the block design, the silicon powder is broken down when sprayed and diffused more thoroughly; the outer shell is equipped with a set design that injects combustible gases and combustible gases into the interlayer to ensure that the flame is in full contact with the silicon powder.
Through more thorough diffusion and sufficient flame contact, the silicon powder is avoided to agglomerate after melting, improve the product pass rate, reduce production costs, and improve the melting efficiency of the silicon powder.

[0002] The spheroidization of silicon micropowder is a process of converting irregularly shaped silicon micropowder particles into spherical particles. Spherical silicon micropowder has important value in many high-end application fields due to its excellent physical and chemical properties. Spheroidized silicon micropowder is usually produced using a spheroidizing furnace. The material nozzle of the spheroidizing furnace is one of the key components in the spheroidization process. It is responsible for ejecting the molten material through the nozzle to form fine particles. When the existing material nozzle ejects silicon micropowder, especially silicon micropowder with a diameter of less than 5 microns, the silicon micropowder does not diffuse thoroughly at the nozzle, causing the silicon micropowder to agglomerate after melting, reducing the qualified rate of the product and increasing the production cost of the product. Secondly, the existing material nozzle and combustible gas nozzle usually adopt a split design, resulting in insufficient contact between the material and the flame, and part of the silicon micropowder cannot be melted, reducing the qualified rate of the product and increasing the production cost of the product.

[0022] Example 1: See Figures 1 to 5It is a schematic diagram of each structure of the utility model, including an inner shell body 1 and an outer shell body 2. The inner shell body 1 and the outer shell body 2 are both hollow and the outer shell body 2 is mounted on the inner shell body 1. The axes of the inner shell body 1 and the outer shell body 2 are on the same straight line. A vibration rod 12 is arranged inside the inner shell body 1. The upper end of the vibration rod 12 is connected to the inner shell body 1 through a support rod 11. The fulcrum of the vibration rod 12 is more easily subjected to force and vibrates at the end. A conical stopper 13 is connected to the lower end of the vibration rod 12. The maximum diameter of the stopper 13 is smaller than the inner diameter of the inner shell body 1. The stopper 13 is flush with the lower end of the inner shell body 1, which is convenient for breaking up and spraying out the material.
[0023] Specifically, a plurality of support blocks 16 are disposed outside the inner shell 1, and the plurality of support blocks 16 are gap-matched with the inner wall of the outer shell 2. The inner shell 1 can be fixed in the outer shell 2 through the support installation of the support blocks 16, thereby ensuring the stability of the gas passage.
[0024] Specifically, the lower end of the outer shell 2 is flush with the lower end of the inner shell 1 .
[0025] Specifically, an annular limit block 23 is disposed inside the outer shell 2 , and the limit block 23 is disposed corresponding to the support block 16 , so as to facilitate the positioning of the inner shell 1 and the outer shell 2 during installation.
[0026] Specifically, a contracted nozzle portion 21 is provided at the lower portion of the outer shell 2 .
[0027] Specifically, the upper end of the inner shell 1 is provided with a first thread 15, and the inner side of the upper end of the outer shell 2 is provided with a second thread 22, which is convenient for connecting the pipeline.
[0028] Specifically, a trumpet-shaped cavity 14 is provided in the stopper 13 . The design of the cavity 14 enables the side wall of the stopper 13 to resonate when vibrating, thereby enhancing the vibration effect.
