Description

Technical Field

[0001] The utility model belongs to the technical field of silicon carbide production and processing, and in particular relates to a silicon carbide production and processing stirring and mixing device. Background Art

[0002] Silicon carbide raw material is an inorganic substance, which is made of quartz sand, petroleum coke, and sawdust raw materials through high-temperature smelting in a resistance furnace. Silicon carbide raw material is a semiconductor, which exists in the form of extremely rare mineral moissanite in nature. Silicon carbide raw material needs to be stirred during processing. Stirring is a process of mixing two or more substances together, which is usually achieved with the help of a stirrer mechanical device. The purpose of stirring is to evenly mix the gas, liquid or suspended particles in the solution. It can be achieved through forced convection and uniform mixing devices, such as the internal components of the stirrer. However, in the existing stirring device, the stirring speed cannot be controlled, which may cause uneven stirring of the silicon carbide raw material and affect the quality of the silicon carbide raw material. Therefore, a silicon carbide production and processing stirring and mixing device is proposed.

[0003] For example, the Chinese patent with publication number CN220460528U discloses a silicon carbide production and processing stirring and mixing device. Its technical solution includes: a silicon carbide raw material production and processing main body shell, a motor and a rotating rod, the top of the silicon carbide raw material production and processing main body shell is fixedly connected with a motor, the bottom of the motor is fixedly installed with a rotating rod extending to the inside of the silicon carbide raw material production and processing main body shell, the outer side of the rotating rod is fixedly connected with a spiral auger blade, the bottom of the rotating rod is fixedly installed with a bottom plate, the inner wall of the silicon carbide raw material production and processing main body shell is provided with a crushing track, and the inside of the bottom plate is provided with a groove.

[0004] The above patent has the following problems:

[0005] Compared with the stirring equipment in the prior art, which cannot control the stirring speed, stirring too fast will easily generate bubbles, stirring too slowly will easily cause precipitation, affecting the quality of the silicon carbide raw material after stirring, delaying the normal use of the silicon carbide raw material, and the silicon carbide raw material in the prior art is not classified and dried after stirring, which is easy to make mistakes when taking the material, and the storage time of the silicon carbide raw material cannot be increased, reducing the service life of the silicon carbide raw material. In view of this, we propose a silicon carbide production and processing stirring and mixing device. Utility Model Content
