Background

In the preparation process of solar grade polysilicon, high-purity primary polysilicon and some recycled materials are generally adopted as raw materials for ingot casting or purification, while silicon is used as a non-renewable resource, so that the storage capacity is very limited. Therefore, in order to improve the utilization rate and save the silicon material cost in the photovoltaic industry, the silicon materials such as pot bottom materials, head and tail materials, silicon chips and the like generated in the processes of drawing or ingot casting, cutting, square cutting and the like of monocrystalline silicon and polycrystalline silicon rods are recycled at present. However, the surface of the silicon material is polluted during the processes of processing, transportation and storage, and the pollutants mainly comprise organic matters such as an oxide layer, metal ions introduced on a diamond wire or a band saw, slurry and the like.

In order to ensure the quality of the recycled material after cleaning, almost all pollutants on the surface of the recycled material need to be cleaned by acid. For common polycrystalline silicon or monocrystalline silicon circulating materials, the cleaning process is relatively strict, and for cleaning monocrystalline-like seed crystals, the process control is more strict. The seed crystal is formed by pulling a single crystal, is a processed product of a finished product single crystal rod, and is expensive and fragile. Therefore, the cost of the seed crystal is relatively high, and the periphery of the seed crystal can not be collided in the cleaning process, and the seed crystal needs to be cleaned and has no acid liquid residue. At present, in the current ordinary pickling basket, because of not making specific design to lead to the seed crystal often can collide with, corner or edges and corners appear breaking or pit in the cleaning process, influence seed crystal quality or scrap.

Accordingly, there is a need to provide a seed crystal cleaning box to solve the above problems.
