Description

Technical Field

[0001] The utility model relates to the technical field of granulation equipment, in particular to a granulation system for silicon carbide ceramics. Background Art

[0002] Carborundum, also known as silicon carbide, is made from quartz sand, petroleum coke, sawdust and other raw materials through high-temperature smelting in a resistance furnace. Silicon carbide is also known as carbon silicon stone. Among contemporary non-oxide high-tech refractory raw materials such as C, N, and B, silicon carbide is the most widely used and most economical one. It can be called carborundum or refractory sand. The granulation process of silicon carbide requires crushing, rolling and granulation.

[0003] For example, the application number is 202322245902.9, which is a granulation system for silicon carbide ceramics. By setting up components such as a drive motor, an inclined plate, a screen plate, a spring, a mounting plate and a push rod, the material falls on the top of the screen plate after granulation is completed, and the output shaft of the drive motor drives the two push rods, which then squeeze the screen plate, and the screen plate squeezes multiple springs at the bottom. When one end of the push rod is separated from the screen plate, the screen plate moves upward under the thrust of the spring to realize the vibration function. After the material on the screen plate is vibrated, the particle size smaller than the inner diameter of the screen plate leakage hole will fall on the inclined plate, and the material will be taken out by opening the second discharge door. The material with a particle size larger than the inner diameter of the screen plate leakage hole will remain on the top of the screen plate, thereby realizing material screening. There is no need to manually introduce the particles into the screening equipment again, reducing labor.

[0004] It has the following disadvantages:

[0005] When the diameter of the screened material matches the size of the sieve holes of the screen plate, the screened material is easily stuck in the sieve holes on the screen plate. It is not easy to discharge the material stuck in the sieve holes by simply vibrating the screen plate, and the blockage of the sieve holes will reduce the screening efficiency of the screen plate for the material.

[0006] Therefore, we proposed a granulation system for silicon carbide ceramics to solve the above problems. Utility Model Content
