Silicon rod crushing and screening mechanism and crusher

Abstract

The invention provides a silicon rod crushing and screening mechanism and a crusher. The silicon rod crushing and screening mechanism comprises a crushing mechanism and a screening mechanism; the crushing mechanism comprises a crushing device and a control device arranged on one side of the crushing device; the crushing device comprises a crushing cavity, and the side walls of the crushing cavitycomprise the movable side wall and the fixed side wall; the crushing cavity comprises a feeding inlet and a discharging outlet which are oppositely formed; the control device is connected with the movable side wall to control the movable side wall to make eccentric motion; the screening mechanism is arranged at the discharging outlet and comprises a screening plate and a vibration device for enabling the screening plate to vibrate; and a plurality of falling holes are formed in the screening plate, and the size of the falling holes close to the discharging outlet is smaller than that of the falling holes away from the discharging outlet. By enabling the movable side wall to make eccentric motion, the size of the discharging outlet is in a changing state, then the size of the discharging outlet is larger than a preset size of the discharging outlet, and finally, the silicon rod crushing and screening mechanism can crush various silicon particles of different sizes.

Description

technical field [0001] The invention belongs to the technical field of silicon material manufacture, and in particular relates to a silicon rod crushing and screening mechanism and a crusher. Background technique [0002] In the photovoltaic industry, raw silicon rods need to be broken into fine silicon particles through a crushing process. The crushing process is usually divided into transmission-crushing-screening-collection and other processes. It can be seen that the crushing and screening process occupies an important position in the entire crushing process. [0003] At present, in the process of crushing and screening, due to the limitation of the internal structure of the crushing mechanism, only silicon particles not larger than the initial size can be crushed each time. Therefore, if the customer needs silicon particles of different sizes, it is necessary to continuously adjust the crushing mechanism to proceed Repeated processing and crushing effect are not good a...

[0003] At present, in the process of crushing and screening, due to the limitation of the internal structure of the crushing mechanism, only silicon particles not larger than the initial size can be crushed each time. Therefore, if the customer needs silicon particles of different sizes, it is necessary to continuously adjust the crushing mechanism to proceed Multiple processing, and the effect of crushing is not good at the same time, which greatly affects the efficiency and cost of production
