In recent years, with the development of science and technology, the application fields of high-purity silicon carbide powder have become more and more extensive, especially in the fields of semiconductors, ceramics and refractory materials. Silicon carbide micropowder is mainly 1200# and 1500#. Since silicon carbide micropowder is mainly used in the abrasive industry, there are special requirements for the grading of micropowder. No large particles can appear in the micropowder. The silicon carbide slurry needs to be stirred evenly by a stirring device, and then dried by a drying machine. After that, it is sieved by a screening machine to obtain 1200# and 1500# silicon carbide micropowder.
[0003] The traditional silicon carbide micropowder stirring device has only a single stirring rod for stirring, and the stirring effect on the slurry at the bottom is not very ideal; the traditional silicon carbide micropowder stirring device can only stir the slurry, and cannot dry the stirred slurry. It needs to be poured into a drying machine for drying, which is more troublesome; the traditional silicon carbide micropowder stirring device cannot grade the processed silicon carbide micropowder, and a grading machine is needed for grading, which consumes extra manpower to process. Therefore, a new type of silicon carbide micropowder stirring device is proposed to address the above problems. Utility Model Content

[0023] A novel silicon carbide micropowder stirring device comprises a shell 1, a feed plate 2 is fixedly connected to the inner side of the shell 1, a protective net 3 is fixedly connected to the inner side of the feed plate 2, a rotating shaft 4 is connected through the center position of the top of the shell 1, a motor 5 is fixedly connected to the top of the rotating shaft 4, a stirring rod 6 is fixedly connected to the outer side of the rotating shaft 4, a stirring tooth 7 is fixedly connected to the outer side of the stirring rod 6, a stirring plate 8 is fixedly connected to the bottom end of the rotating shaft 4, an upper inclined plate 9 is fixedly connected to the left side of the shell 1, a lower inclined plate 10 is fixedly connected to the left side of the shell 1 relative to the bottom end of the upper inclined plate 9, and the upper inclined plate 9 and one side of the lower inclined plate 10 are fixedly connected. A side plate 19 is fixedly connected thereto, a limiting groove 18 is provided at the top of the upper inclined plate 9, a baffle 11 is slidably connected thereto, a handle 12 is fixedly connected to the top of the baffle 11, a card slot 17 is provided at the top of the lower inclined plate 10, a screen 13 is fixedly connected to the bottom inner end of the outer shell 1, a discharge plate 14 is fixedly connected to the bottom end of the outer shell 1, a support leg 15 is fixedly connected to the side of the discharge plate 14 away from the outer shell 1, a fan blade 16 is fixedly connected to the outer side of the rotating shaft 4 at the middle position between the outer shell 1 and the protective net 3, a heating layer 20 is fixedly connected to the inner side of the outer shell 1, and a telescopic plate 21 is fixedly connected to the top of the screen 13.
[0024] There are sixteen stirring teeth 7, and each group of four is symmetrically arranged on the surface of the stirring rod 6. Four stirring teeth 7 and one stirring rod 6 are grouped together, for a total of four groups, and are symmetrically arranged on both sides of the rotating shaft 4. The stirring plate 8 is rectangular in shape and fits tightly with the telescopic plate 21. There are four supporting legs 15, and they are symmetrically arranged at the bottom edge of the outer shell 1.
[0025] Working process: when it is necessary to stir silicon carbide powder, the device is powered by an external power supply, and silicon carbide slurry is poured in through the notch at the top of the outer shell 1, and flows into the interior of the device through the feed plate 2. Then, the motor 5 drives the shaft 4 to rotate, and the shaft 4 drives the stirring rod 6, stirring teeth 7 and stirring plate 8 to rotate, so as to fully stir the silicon carbide slurry at multiple angles. During the stirring process, the heating layer 20 heats and dries the silicon carbide slurry. When the shaft 4 rotates, it also drives the fan blades 16 to rotate, so as to air-dry the silicon carbide slurry, and cooperates with the heating layer 20 to achieve a better drying effect. The telescopic plate 21 belongs to the prior art and is similar to the principle of an electric awning. The telescopic plate 21 can prevent the undried silicon carbide slurry from flowing into the screen 13 in advance, and observe whether the silicon carbide slurry is completely dried by the eyes. The silicon carbide slurry will become silicon carbide micropowder after drying. After drying, the telescopic plate 21 will shrink to the right, so that the silicon carbide micropowder contacts the screen 13. At this time, the wind force generated by the fan blades 16 can accelerate the silicon carbide micropowder to pass through the screen 13. The screen 13 can only pass the smaller silicon carbide micropowder of size 1200#. The silicon carbide micropowder of size 1200# will slide along the discharge plate 14 to the designated position, and the large silicon carbide micropowder of size 1500# will remain in the shell 1. Then, the handle 12 is manually held and pulled upward to drive the baffle 11 to pull out the upper inclined plate 9. The silicon carbide micropowder of size 1500# will be transported to the designated position through the lower inclined plate 10 under the blowing of the fan blades 16 and the stirring of the stirring plate 8, thereby completing the screening of silicon carbide micropowders of different specifications.
