[0002] High-purity crystalline silicon is the main raw material for the preparation of electronic components and solar cells, and is an important electronic information material. At present, the solar photovoltaic industry is a new industry, but there are the following problems in its development process: the production of crystalline silicon wafers Enterprises have increased demand for cutting fluid and crystal silicon wafer cutting blades, and these manufacturers cannot handle the waste mortar in a timely and effective manner, resulting in a continuous decline in slicing profits. All slicing manufacturers can only reduce costs, focusing on In the recycling of waste mortar, using recycled liquid and recycled sand ginseng new liquid and new sand for cutting can basically save about 40% of the cost of mortar

[0003] In the prior art, the mortar used for crystalline silicon cutting production is not clearly separated during recycling, and the crystalline silicon powder, silicon carbide fine powder and slag after cutting cannot be effectively separated. The research on the recycled mortar is very sensitive to climate temperature. Therefore, in general, the viscosity is too high in the low-temperature centrifuge and the centrifugation cannot meet the recovery requirements.

[0004] At present, there are only a few online recycling and processing systems for manufacturing crystalline silicon cutting waste mortar at home and abroad, which are basically an overall structure, that is, the structure is made of carbon steel special-shaped pipe welding combination and complicated pipeline welding machines. Generally, from manufacturing to user use The whole cycle is very long, and it is not difficult to see in its manufacturing process: its structure is bloated, bulky and clumsy, the pipeline is messy, it is difficult to meet the ideal requirements in inspection, repair and maintenance, and its equipment transportation and installation cost a lot of money , material resources and time, easily damaged, and extremely inconvenient, so the early on-line recycling and processing equipment for waste mortar from crystal silicon cutting should completely change the manufacturing mechanism and equipment transformation
