Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to production equipment for silicon carbide ceramic materials. Background Art

[0002] Silicon carbide ceramic is a high-performance ceramic material with excellent wear resistance, high temperature resistance, corrosion resistance and other characteristics. It is often used in the manufacture of high-temperature furnaces, mechanical parts, ceramic cutting tools, etc.

[0003] The main raw materials for its production generally include silicon carbide powder (SiC), binders, additives, etc. The silicon carbide powder, binders and additives are evenly mixed in a certain proportion, and the mixed materials are made into a blank of the desired shape through a molding process. However, traditional equipment only stirs and mixes the materials by a stirring rod or a stirring blade. Since the stirring rod or the stirring blade occupies a smaller volume than the material body, the contact area with the material body is smaller, resulting in a longer time required to mix the material body evenly. Alternatively, the stirring effect is improved by increasing the number of stirring rods or stirring blades, but this method increases the volume share of the stirring equipment and also increases the equipment cost.

[0004] In order to solve the above problems, we proposed a production equipment for silicon carbide ceramic material. Utility Model Content

The outer walls of the two rotating shafts 9 are fixedly sleeved with two sprocket wheels 11. The two sprocket wheels 11 on the same rotating shaft 9 are respectively close to the left and right ends of the mixing barrel 5. The outer wall of the mixing barrel 5 is fixedly sleeved with a chain ring 12 matching the sprocket wheel 11. A toothed chain 13 is sleeved between the chain ring 12 and the corresponding two sprocket wheels 11.

[0022] A driving structure is provided on the right side of the connecting rod 1 6, and the driving structure includes a motor 14 fixedly connected to the right side walls of the two connecting rods 2 7, and a driving end of the motor 14 is fixedly connected to a sprocket 2 15, and an end of the rotating shaft 9 located on the front side extends out of the right side of the connecting rod 1 6 and is fixedly connected to a sprocket 3 16, and a toothed chain 2 is commonly provided between the sprocket 3 16 and the sprocket 2 15.
