Description
Technical Field
The utility model relates to the technical field of silicon material screening, in particular to a silicon material screening and transporting device.
Background
In the photovoltaic industry, silicon materials are commonly used in the production process, and the diameter of the silicon material is between 1mm and 15 mm. The silicon material can be used for preparing polycrystalline silicon, and before the silicon material is used, the silicon materials with different diameters need to be classified, cleaned and the like, and then subsequent work can be carried out. The preparation of the polysilicon needs to use a silicon material with a specific diameter, and the existing silicon material screening step generally comprises the steps of screening the silicon material with a certain specification and then further screening the silicon material through another production line. The screening method undoubtedly has certain requirements on the scale of a production site, and has certain limitation on the subsequent scale-up of production.
SUMMERY OF THE UTILITY MODEL
Aiming at the problem that screening equipment of silicon materials in the prior art occupies a large area, the utility model provides a silicon material screening and conveying device to solve the problem.
A silicon material screening and conveying device comprises a screening device and a conveying device. The screening device comprises a feed hopper at the top, a screening channel vertically penetrating through the screening device and a plurality of screens; the screen is arranged in the screening device from top to bottom according to the mesh number of the screen, and the mesh number of the screen is reduced from top to bottom; the screen is arranged in a drawing mode; a blanking device is arranged at the lowest part of the screening channel; a conveying device is arranged below the blanking device; the conveying device comprises a conveying belt and a bracket for fixing the conveying belt.
Further, the screening device is provided with a vibrator. When the screening is carried out, the silicon material can be rapidly screened through vibration.
Further, the blanking device is an inverted trapezoid body. Therefore, the screened silicon materials can fall on the conveyor belt in a concentrated mode, and the silicon materials are prevented from falling to the position outside the conveyor belt to pollute the site environment.
Further, the number of the screen meshes is four.
Further, the feed hopper is provided with a cover. Since the silicon material having a small particle diameter is easily floated in the air, the provision of the cover prevents the generation of dust.
Further, the conveyor belt is driven by a motor.
The working principle of the utility model is as follows: when the silicon material is screened, the silicon material is firstly guided into a feed hopper, and the mesh number of the screen mesh is reduced from top to bottom in sequence, so that the silicon material with small particle size is firstly screened out and is transmitted out and collected by a conveying device; when no more silicon material falls, pulling out the screen with large mesh number, and then screening the silicon material with larger particle size; the above operations are repeated to separate the silicon materials with different particle size ranges.
The utility model has the beneficial effects that:
the utility model can sieve the silicon materials with different particle sizes by simply replacing the screen; meanwhile, the occupied area is small, and the silicon material is in a relatively closed space in the screening process, so that no dust is generated.
