A device for industrialized reuse of smelting slag tailings and its process method

Abstract

The invention discloses an industrial reuse device for smelting furnace slag tailings and a process method thereof, and relates to the technical fields of energy saving, emission reduction and green environmental protection. The industrial reuse device for smelting slag tailings includes an external control mechanism for external control, a rotary vibration mechanism for rotating and vibrating, an air bag extrusion mechanism for air bag extrusion, and a magnetic repulsion mechanism for magnetic repulsion. The repulsion mechanism and the cross extrusion mechanism used for cross extrusion, the outer wall of the external control mechanism is fixedly connected with a rotary vibration mechanism. The smelting slag tailings industrial reuse device moves on the spiral slope through the screw rod and the roller, so that the drying cylinder rises and falls, and the drying cylinder is continuously vibrated, so that the copper tailings slag inside the drying cylinder is continuously The vibration ensures the separation of the copper tailings slag adhered together, and the continuous up and down vibration of the drying cylinder expands the gap between the copper tailings slag in the drying cylinder to ensure the drying of the copper tailings slag.

Description

Technical field [0001] The present invention relates to energy saving and emission reduction and green environmental protection technology field, specifically a smelting furnace slag tailings sand industrialization reuse device and process method thereof. Background [0002] With ore powder part of the replacement of cement products to produce concrete and cement mortar, is the state to encourage the development of energy saving and emission reduction and green environmental protection industry, social and economic benefits will be very obvious, since this century, ore powder for cement admixture industry booming, the main raw material used is an active ironmaking blast furnace water quenching slag, also partially mixed with other solid waste, in recent years, created a precedent for the development and production of ore micronized ore with iron and lead zinc ore tailings development and production of ore powder, the technology in addition to the promotion and application in some...

AI Technical Summary

Problems solved by technology

[0003] The process path of using slag to select copper tailings to produce ore micropowder is as follows: the tailings enter the grinding through the tailings conveying system, and the materials are ground in the grinding system. At the same time, the main fan system is connected to the heating furnace through the air pipeline, and the powder is collected. Drying, winnowing, conveying and coarse material circulation, etc., are carried out on the materials by dust collectors, chute-type air conveyors, bucket elevators, etc., until the micro-powder products enter the product warehouse to be loaded and sold. Drying is the slag selection. Copper tailings is an important link in the production of ore powder. Copper tailings are mixed with a large amount of water or some viscous liquids, so that the copper tailings stick together. The existing device cannot dry the copper tailings. The intermediate material with copper tailings slag adhered together is dried
