detailed description

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

As shown in Figure 1, a silicon material sorting device includes: a support 1 and a screening device that is horizontally arranged on the top of the support 1, transports silicon material from the head end to the tail end, and screens the transported silicon material 2; the bottom of the screening device 2 near the head end is provided with a vibrating device 6; the inner bottom surface of the screening device 2 near the tail end is arranged with a plurality of screens 21 at intervals along the silicon material conveying direction, each of the A silo 7 is provided directly below the screen 21; each of the silos 7 is provided with a discharge port; the mesh size of the plurality of screens 21 gradually increases along the silicon material conveying direction.

When sorting the silicon material, the head end of the screening device 2 receives the silicon material crushed by the silicon rod crushing equipment, and the vibrating device 6 drives the screening device 2 to vibrate, so that the silicon material moves in the screening device 2 and passes through multiple sieves in turn. Net 21, the silicon material whose size is smaller than the mesh size of the first screen cloth 21 is screened out by this screen cloth 21, and enters the feed bin 7 corresponding to the first screen cloth 21, and the silicon material whose size is larger than the first screen cloth 21 The silicon material with the mesh size moves to the next screen 21, and is screened in sequence, so that the silicon materials of different sizes are sorted out from the outlets of different feed bins 7, and the finally unscreened silicon material is Enter the secondary crushing device 4 for secondary crushing, and finally enter the screening device 2 for secondary screening. In this embodiment, four screens 21 are arranged on the inner surface near the tail end of the screening device 2, and the silicon material can be divided into four categories according to the size. The silicon material sorting device proposed by the utility model realizes the size sorting of the silicon material, and the silicon material sorting efficiency is high.

Specifically, the vibrating device 6 is a vibrating motor, and the vibrating motor is arranged at the bottom of the screening device 2. When the vibrating motor works, it drives the screening device 2 to vibrate.
