Copper slag screening device and using method thereof

Abstract

The invention provides a copper slag screening device and a using method thereof. The copper slag screening device comprises a base, wherein a primary screening bin is arranged at the upper end of thebase, dust suction plates are correspondingly arranged at the upper end and the lower end of one side face of the primary screening bin, a screening barrel is installed in the primary screening bin,and the front surface of the primary screening bin communicates with a discharging pipe; a secondary screening box is connected to the position, located on the front side of the primary screening bin,of one end of the discharging pipe, a spraying plate is arranged on the position, located on one side of the discharging pipe, of the upper surface of the secondary screening box, and a discharging table is installed at the position, corresponding to one end of the discharging pipe, of one side in the secondary screening box; and a plurality of partition plates are distributed in the secondary screening box and located on the side close to the discharging table at equal intervals. According to the copper slag screening device and the using method thereof, copper slag is firstly crushed to achieve primary separation of the copper slag and ash slag, and then secondary screening treatment is achieved by utilizing different gravity values of the copper slag and the ash slag in cooperation with the action of water flow and air plates, so that crushing, absorbing and water floating separation are integrated, and the screening efficiency of the copper slag is further improved.

Description

technical field [0001] The invention relates to the technical field of copper slag screening, in particular to a copper slag screening device and a use method thereof. Background technique [0002] As we all know, my country is rich in mineral resources, but the amount of resources per capita is poor. With the depletion of copper ore resources, people pay more and more attention to low-grade copper ore. my country is a big consumer of copper ore resources, and copper ore resources are also scarce, forming a series of sharp contradictions and resource tensions. . [0003] Specifically, copper slag is industrial waste slag produced in the process of copper smelting, which is a kind of non-ferrous metal slag. The waste slag discharged from reverberatory furnace copper smelting is reverberatory furnace copper slag, and the waste slag discharged from blast furnace copper smelting is blast furnace copper slag. Among them, for every ton of copper smelted, 10-20 tons of slag will ...

AI Technical Summary

Problems solved by technology

Therefore, in the process of copper smelting, a lot of copper slag will be produced, which contains a lot of copper components. If it is not used, it will cause a lot of waste

[0004] However, the disadvantages of the existing copper slag refining equipment and technology are that the equipment is more complicated, and the screening of copper slag is more cumbersome, the separation efficiency of copper slag is also low, and the capital invested is also large.
