AI Technical Summary

Technical Problem

Existing silicon nitride grinding equipment requires frequent maintenance when the feed trough is blocked, which increases maintenance costs and downtime, affecting equipment operation and material quality. In particular, easily perishable materials may lead to a decline in processing quality.

Method used

A silicon nitride grinding device was designed, which includes a material unblocking device and a lubrication device. The material unblocking device clears the feed trough to avoid blockage, and the lubrication device cools and lubricates the material to ensure the stability and efficiency of the grinding process.

Benefits of technology

It effectively avoids clogging of the feed trough, improves grinding efficiency, reduces equipment maintenance frequency, ensures material quality and processing accuracy, and prevents particles from breaking or falling off due to friction.

Abstract

This invention discloses a silicon nitride grinding device, relating to the technical field of silicon nitride grinding devices. The device includes a support frame and a collection box. A conical cylinder is fixedly mounted on the upper surface of the support frame, and the collection box is disposed on the lower surface of the support frame. A feed trough is fixedly mounted on the upper surface of the conical cylinder, and a water storage tank is fixedly mounted on the circumferential surface of the conical cylinder. A water spray head is provided on the inner wall of the conical cylinder. A rotating shaft is rotatably mounted on the upper surface of the inner wall of the conical cylinder, and a grinding head is fixedly mounted on the lower surface of the rotating shaft. A grinding disc is fixedly mounted on the inner wall of the conical cylinder. A material unblocking device is also provided inside the conical cylinder. When the feed trough is blocked, it affects the grinding efficiency, potentially causing a decrease in output or production stoppage. Blockage causes material to accumulate in the feed trough, increasing the pressure and stress on the material. If this blockage persists for a long time, it may damage the feed trough.
