Description

Technical Field

[0002] Metallic silicon is a product smelted by silica and carbonaceous reducing agent in a submerged arc furnace. The content of the main component silicon is about 98%, and the remaining impurities are iron, aluminum, calcium, etc. The additional products of metallic silicon include microsilicon powder, edge silicon, black silicon, metallic silicon slag, etc. Microsilicon powder is also called silica ash, which is widely used in refractory and concrete industries, and silicon slag is used for recycling steel slag into pig iron, ordinary casting, etc. Silicon slag can well increase the furnace temperature, increase the fluidity of molten iron, effectively discharge slag, increase the grade, and improve the toughness and cutting ability of castings. Therefore, the demand for a silicon slag collection device for industrial silicon smelting is growing.

Through the screening mechanism, the silicon slag is poured into the box from the feeding port, and the screening plate is driven to move left and right by the hydraulic rod to perform preliminary screening and filtering of the silicon slag, and the filtered silicon slag is dropped into the collection box through the screening holes opened on the top surface of the screening plate, and the first motor is started at the same time, and the two pulleys are driven by the first motor for transmission, and the right end of the first motor drives the first threaded rod and the rotating blade to rotate, so as to perform preliminary stirring treatment on the silicon slag, and the silicon slag can be better collected; by setting a water tank and a water outlet pipe, the second threaded rod and the stirring blade are driven to rotate by the pulley, so that the silicon slag inside the collection box can be better cleaned, which is convenient for the subsequent collection of silicon slag.
