Water recycling and safe crushing device for silicon powder production line

Abstract

The invention discloses a water recycling and safety crushing system for a silicon powder production line. A separating trough used for material receiving is arranged at the lower rear side of a discharge hole of a horizontal mixer; the interior of a water tank is divided into three chambers by two separators; a water pump is arranged outside the water tank; a water inlet of the water pump is connected with an outlet of an intake pipe; an inlet of the intake pipe extends into a clear water chamber; a water outlet of the water pump is connected with an inlet of an outlet pipe; an outlet of the outlet pipe is connected with a water inlet of the horizontal mixer; a rack is arranged at the rear of the water tank; the rack is provided with a vertical crusher; a chute is arranged above the vertical crusher; the upper end of the chute is provided with a hopper. According to the water recycling and safety crushing system disclosed by the invention, a silicon briquette is washed in a manner of stirring, so that cleaning efficiency is high, and a washing effect is good; sewage from washing is collected and treated by the water tank, and can be recycled, therefore water consumption is effectively reduced, and water resources are saved; air is isolated by nitrogen filling during a crushing process, so that an explosion can be effectively stopped, and safety is high.

Description

technical field [0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to a water recycling and safety crushing device for a silicon powder production line. Background technique [0002] Silicon powder is prepared from silicon block as raw material and is widely used in various high-tech industries. At present, the preparation method of silicon powder is to wash first and then crush. The cleaning method generally adopts washing or soaking. Not only the cleaning efficiency is low, the labor intensity of the workers is high, but also the cleaning effect is poor; while the crushing method usually adopts direct extrusion crushing. Or direct impact crushing, there is no isolation of air in the crushing process, and there are deficiencies such as prone to explosion and poor safety. Therefore, on the premise of ensuring processing efficiency, how to safely produce silicon powder is a technical problem that the industry is working hard t...
