[0002] Silicon carbide is an inorganic substance, which is made of quartz sand, petroleum coke (or coal coke), sawdust (salt is needed to produce green silicon carbide) and other raw materials through high temperature smelting in a resistance furnace. Silicon carbide is a semiconductor that exists in nature in the form of a rare mineral moissanite. In the process of processing silicon carbide, the required raw materials need to be mixed, so this type of mixing mixer plays a very important role.

[0003] In view of this, Chinese patent No. CN217909955U proposes a mixing mixer for the production of silicon carbide products. The utility model provides a micro high-pressure pump, a cylinder, a mounting plate, a nozzle and other components, so that only the micro high-pressure pump and the cylinder need to be started to remove the materials adhered to the inner wall of the mixing barrel without manual operation. It is not only simple in structure and easy to operate, but also has high cleaning efficiency, thereby improving production efficiency. However, the mixer in the above technical solution cannot clean the materials deposited on the bottom of the inner wall of the mixer during the cleaning process, so that the materials accumulate for a long time, which can easily make the mixer unusable, thereby reducing the service life of the device.
