Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a photovoltaic polysilicon recycling and reproducing feeding device. Background Art

[0002] Polycrystalline silicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooling conditions, silicon atoms are arranged in the form of diamond lattices to form many crystal nuclei. If these crystal nuclei grow into grains with different crystal plane orientations, these grains will combine and crystallize into polycrystalline silicon. Polycrystalline silicon is widely used in photovoltaics, and a loading device is required for the recycling and reproduction of polycrystalline silicon.

[0003] The Chinese patent publication number is: CN215743745U, a photovoltaic polysilicon recycling and reproducing feeding device, the technical solution provided by the patent document is: including a material rack and a production box, the production box is located on one side of the feeding rack, a slope is set on one side of the feeding rack, a limit groove is set on one side of the slope, a roller is installed inside the limit groove, and the outer surface of the roller is connected to a first rotating shaft. The utility model uses a roller, a feeding shaft and a slope, and the user puts the polysilicon on the slope in turn, places it with the feeding shaft at intervals, and uses the control panel to start the first motor. The output end of the first motor uses the first conveyor belt to control the rotation of the three first rotating shafts. The three first rotating shafts are in the same rotation state. The rotation of the first rotating shaft drives the roller to rotate, and the roller drives the feeding shaft to rotate, thereby driving the polysilicon to move one by one on the slope to ensure the orderly entry of the polysilicon.

[0004] In order to solve the problem that the existing feeding device has a relatively simple structure, when polysilicon is fed, it is directly dropped into the device for recycling by a conveyor belt, which will block the feed port of the device, affecting the recycling and reproduction of polysilicon, and at the same time of feeding, it cannot be guaranteed that the polysilicon enters in sequence and in an orderly manner, which will also block the feed port and affect the production efficiency of polysilicon, the prior art adopts a roller, a feeding shaft and a ramp, and the user puts the polysilicon on the slope in turn, places it at intervals with the feeding shaft, and starts the first motor by using the control panel. The output end of the first motor uses the first conveyor belt to control the rotation of the three first rotating shafts, and the three first rotating shafts are in the same rotation state. The rotation of the first rotating shaft drives the roller to rotate, and the roller drives the feeding shaft to rotate, thereby driving the polysilicon to move one by one on the slope, ensuring that the polysilicon enters in an orderly manner for processing. However, there will be a situation where the polysilicon slides backward due to centrifugal force during transmission, which leads to a problem of reduced work efficiency. Utility Model Content
