Description

Technical Field

[0001] This utility model belongs to the field of centrifugal atomizer technology, specifically a high-speed centrifugal atomizer. Background Technology

[0002] The working principle of the high-speed centrifugal atomizer is as follows: the atomizing disc is driven by a motor to rotate at high speed, which generates a strong centrifugal force. When the slurry is delivered to the atomizing disc, the centrifugal force of the atomizing disc does work on the slurry, causing it to be sprayed through the small holes around the atomizing disc and form a fine mist. Then, the slurry is heated at high temperature in the drying chamber to evaporate the water vapor inside the slurry, thereby obtaining uniformly fine, spherical dried particles.

[0003] The atomizing disc is the core component of a high-speed centrifugal atomizer. In existing high-speed centrifugal atomizers, the atomizing disc usually has only one inner cavity, and the inner diameter of the atomizing holes around the atomizing disc is usually relatively large. Such atomizing discs are generally more suitable for atomizing and drying slurries with larger particles. However, when atomizing slurries with smaller particles, they cannot achieve more precise atomization. Therefore, this application proposes a high-speed centrifugal atomizer. Utility Model Content

[0025] In use, the peristaltic pump 3 and the liquid supply hose 4 supply slurry. The slurry enters the interior of the combined liquid supply nozzle 8 through the liquid supply pipe 7, and then the combined liquid supply nozzle 8 supplies the slurry to the interior of the atomizing disc 6. The atomizing motor 2 drives the atomizing disc 6 to rotate through the drive shaft 5. The slurry is diverted through the first annular guide disc 12 and the second annular guide disc 13 and enters the interior of the three centrifugal atomizing chambers 14. Then, it is subjected to centrifugal force to achieve atomization. The atomized slurry is discharged through the atomizing through hole 15.
