Silicon material breaker

Abstract

The invention discloses a silicon mixture dispersing machine which can be used for dispersing silicon mixtures, producing spiral airflow and mixing the spiral airflow with the silicon mixtures. The silicon mixture dispersing machine comprises a base, a dispersing barrel and a feed barrel, and the external circumference surface of the dispersing barrel is provided with an annular air intake ring; the dispersing barrel is internally provided with a dispersing disk, and a driving device used for driving the dispersing disk to rotate is arranged below the base; the dispersing disk is provided withdispersing pieces uniformly arranged along the circumference; the annual air intake ring is provided with an air intake cavity and a blast port; air scattering plates are arranged between the air intake cavity and an inner cavity of the dispersing barrel; the air scattering plates are uniformly distributed circumferentially around the center of the dispersing barrel; and one end of the feed barrel communicates with the dispersing barrel, and the external circumference surface of the feed barrel is provided with a feed pipe. The silicon mixture dispersing machine facilitates the powder selection and recycling of the silicon mixtures in the follow-up process.

Description

technical field [0001] The invention relates to the recycling of waste silicon materials, in particular to a silicon material breaking machine. Background technique [0002] It is well known that after the waste silicon material is recycled, it must be treated to a certain extent before it can be reused. Because the recovered waste silicon material will definitely contain a lot of impurities, and the industrial silicon material must have a purity of more than 98%. [0003] After the silicon material is recovered, pretreatment is carried out first, and the waste silicon material is broken into small pieces of about 3 mm. Then put the waste layer of silicon material containing impurities into the container, add lye to ultrasonic alkaline washing; after the reaction is complete, rinse the silicon material with pure water until the pH is about 7; then add acid solution to the silicon material to control the temperature , pressure, and reaction time; after the reaction is compl...

Problems solved by technology

[0004] In the prior art, during pretreatment, the waste silicon material is broken into small pieces of about 3 mm, and then put into a container, and lye is added for ultrasonic alkaline washing; therefore, the waste obtained by breaking the silicon material during the breaking process is Not very uniform, if there are larger particles in it, it will cause incomplete removal of impurities in subsequent steps, resulting in unqualified final product quality
