Description

Technical Field

[0001] The utility model relates to the technical field of silicon nitride processing, in particular to a conveying device for anti-silicon nitride processing. Background Art

[0002] Silicon nitride is an inorganic substance and an important structural ceramic material. It has high hardness, inherent lubricity, and is wear-resistant. It is an atomic crystal and is resistant to oxidation at high temperatures. It can also resist thermal shock and will not break even if it is rapidly cooled or heated. Because of its excellent properties, silicon nitride is often used to manufacture mechanical components such as bearings, turbine blades, mechanical sealing rings, and permanent molds. After the processing and crushing of silicon nitride, a conveying device is often required for discharging. During use, some existing conveying devices for anti-silicon nitride processing use the rotating operation of the spiral blades to achieve uniform conveying of silicon nitride. However, silicon nitride may be mixed with silicon nitride fragments due to incomplete crushing, and it is impossible to separate them from the silicon nitride powder during the conveying process, which is not conducive to subsequent processing and use.

While conveying, the silicon nitride powder will fall onto the material guide frame through the sieving holes at the bottom and be discharged outward, while the silicon nitride fragments that are not completely crushed will gradually be conveyed to the right to the discharge port and fall downward.
