TECHNICAL FIELD
[0001] The utility model relates to polycrystalline silicon technical field, concretely relates to a kind of industrial silicon powder automatic division and screening device. BACKGROUND
[0002] Silicon powder is one of main raw materials for producing polycrystalline silicon, and its purity directly affects the quality of final product. Before silicon powder is put into use, its impurity content must be strictly detected to ensure that the requirement of subsequent process is met. In order to obtain representative sample, finished product silicon powder is usually subjected to division treatment. This process mainly selects a small amount of sample from batch silicon powder according to certain procedure and method, so that the sample obtained can accurately reflect the overall characteristics of the whole batch of material, thereby effectively evaluating the metal and non-metal impurity level in silicon powder through analysis, and laying foundation for high-quality production of polycrystalline silicon.
[0003] If polycrystalline silicon product needs to be detected for bulk metal, the sample needs to be subjected to steps such as crushing, division, mixing and screening. Generally, a dichotomizer is used to divide the sample, i.e. a large amount of original sample is uniformly divided into several small samples, and the divided sample is subjected to screening detection. Manual operation is required when the dichotomizer is used to divide the sample, which is time-consuming and laborious. On the other hand, manual operation is likely to cause certain sample deviation. Therefore, the present application designs a device integrating automatic division and screening, which can set division times and required weight according to requirement, and is accurate in screening, uniform and representative in sample, saves manpower and time, and improves work efficiency.
