Description

Technical Field

[0001] This utility model relates to centrifugal atomizing spray discs, and more particularly to a steel shot centrifugal atomizing spray disc with adjustable nozzle size. Background Technology

[0002] A centrifugal shot blasting disc is a device used to manufacture steel shot. Its main working principle is to throw molten steel out through a high-speed rotating centrifugal disc, allowing it to cool in the air and form shot-shaped objects. Due to different processing requirements, the size of the steel shot to be processed also varies. The size of the finished product can be changed by changing the model of the blasting disc. The replacement process requires complete disassembly, which is time-consuming and labor-intensive, reducing production efficiency.

[0003] Therefore, the existing centrifugal atomizing spray discs need further improvement. Utility Model Content

[0013] In summary, the advantages of this utility model over the prior art are:

[0014] This invention addresses the shortcomings of existing centrifugal atomizing spray discs. Through its structural design, this invention offers the following advantages: it allows for rapid adjustment of the diameter of multiple spray holes according to processing requirements; the threaded adjustment structure enables convenient, quick, and stable adjustment; it avoids the time waste and increased labor costs associated with directly replacing the spray disc; it meets more processing needs, improves production efficiency; and its simple structure makes it easy to use.
