Multifunctional slag crushing and screening device

Abstract

The invention discloses a multifunctional slag crushing and screening device in the technical field of slag treatment. The multifunctional slag crushing and screening device comprises a box body, a vibrating screen assembly and a spiral conveyor; the vibrating screen assembly is located below the box body, the spiral conveyor is fixedly connected to the right side wall of the box body, a bottom feeding port of the spiral conveyor communicates with a right side discharging port of the vibrating screen assembly, the top and the bottom of the box body communicate with a feeding hopper and a discharging pipe respectively, the top of the box body is fixedly connected with a material containing table, and the bottom of an inner cavity of the box body is rotationally connected with a stirring rotating rod through a bearing. The device is simple in structure and convenient to operate, the motor drives the rotating rod to rotate, a belt is matched with a smooth rod, a push rod drives a push plate to reciprocate to gradually and uniformly inject slag, internal blockage caused by slag accumulation is avoided, the crushing efficiency is improved, and the crushing uniformity is improved; through cooperation of the vibrating screen assembly and the spiral conveyor, unqualified slag is re-injected into the box body, the crushing precision is conveniently improved, and wide application is facilitated.

Description

technical field [0001] The invention relates to the technical field of slag treatment, in particular to a multifunctional slag crushing and screening device. Background technique [0002] Furnace slag is also called molten slag. The melt produced in the process of pyrometallurgy floating on the surface of liquid substances such as metals is mainly composed of oxides (silicon dioxide, alumina, calcium oxide, magnesium oxide), and often contains sulfide and a small amount of metal entrainment. [0003] The composition of the slag is adjusted by adding an appropriate amount of flux (lime, quartz stone, fluorite, etc.). During the smelting process, by controlling the composition and properties of the slag, the products of gangue and oxidized impurities can be successfully separated from the molten metal or sulfur, the harmful impurities in the metal can be removed, and the non-metallic inclusions in the liquid metal can be absorbed without being directly affected. Furnace gas ...
