Description

Technical Field

[0001] This utility model relates to the field of silicon carbide material preparation technology, specifically to a casting development device for silicon carbide materials. Background Technology

[0002] Silicon carbide is a ceramic compound composed of silicon and carbon bonded together by covalent bonds. It is a core representative of third-generation semiconductor materials and possesses unique physicochemical properties. A tape casting development device is a specialized piece of equipment used to prepare silicon carbide ceramic green sheets through a tape casting process. Its core function is to uniformly coat a slurry of silicon carbide powder and additives into a thin film, providing a high-precision green sheet for subsequent sintering. However, current tape casting development devices still have the following shortcomings:

[0003] For example, patent document CN216400277U discloses an automated film casting machine. This automated film casting machine, through the coordinated arrangement of a drive motor, a rotating rod, and a stirring rod, can uniformly stir the slurry in the mixing drum. Then, through the coordinated arrangement of a connecting rod and a scraper, it can scrape off the slurry on the mixing drum and the partition, preventing slurry from adhering to the mixing drum and the partition, and facilitating better discharge of the slurry in the mixing drum. It is relatively convenient to use, but it is not convenient for stable and uniform delivery of raw materials, and it cannot guarantee precise control of the raw material delivery amount.

[0014] 1. This utility model incorporates a material conveying assembly, which includes a servo motor, a connecting shaft, a stirring rod, a stirring impeller, a discharge valve, an auger conveyor, a gear metering pump, and a conveying pipe. In use, raw materials are fed into the storage tank.

[0023] The specific operation is as follows: When in use, put all the raw materials into the storage tank 2, start the servo motor 301, so that the servo motor 301 drives the connecting shaft 302 to rotate, and then drives the stirring rod 303 and the stirring impeller 304 to rotate through the connecting shaft 302, thereby continuously stirring the raw materials to prevent them from settling. A heat-conducting jacket is set on the outside of the storage tank 2, and the inside of the jacket can be heated by heat-conducting oil to improve the stirring efficiency.
