Problems solved by technology

The shortcomings of the traditional three-step process to complete the operation are: long process, large investment, low metal recovery rate, and high energy consumption
At the same time, because the blowing and refining are carried out separately in different furnaces, the utilization rate of sulfur is low, the heat loss is large, the operating environment is poor, and the labor cost is high.

Embodiment Construction

[0019] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] A layered series short-process copper smelting device, including a multi-element furnace 1 and a pyrofinishing furnace 3, both of which are rotatable horizontal cylindrical furnaces. The outer shell is made of steel plates, and the inner lining is refractory materials. On the basis, one end of one of the supporting rollers is equipped with a motor and gear transmission, and the furnace body can rotate along the axis; 1-40 spray guns are arranged at the bottom of the furnace, arranged in single or multiple rows; the furnace is connected by chute 2 , consists of one multi-element furnace 1 and two pyrofinishing furnaces 3, and the three furnaces are arranged in a "pin-shaped hierarchical series".

[0021] The bottom spray guns of the multi-element furnace 1 and the pyrofinishing furnace 3 are at -90°~0°~+90° to the vertical line of the bottom of t...

Abstract

The invention discloses a hierarchy cascade short process copper smelting device and process. The device comprises one multi-component furnace and two elemental furnace which are rotary horizontal cylindrical furnaces, wherein a shell is a steel plate; a lining is a refractory material; the furnace body is supported on a base through two carrier rollers; a motor is arranged at one end of one carrier roller; the furnace body can rotate along the axis through gear drive; 1-40 spray guns are arranged at the bottom of the furnace and are arranged in a single row or multiple rows; the furnaces are connected by adopting a chute and the one multi-component furnace and two elemental furnaces are arranged in a hierarchy cascade mode in the shape like a Chinese character pin. The hierarchy cascade short process copper smelting device has the advantages of simple structure, reasonable design, energy conservation and environment friendliness and has high popularization and application values.

Description

technical field [0001] The invention belongs to the field of nonferrous metallurgy, and relates to a short-flow copper smelting device and process. Background technique [0002] At present, the world's more advanced pyrometallurgical copper smelting processes such as flash smelting, Isa top blowing, Noranda side blowing smelting, Vanyukov smelting and so on. Even for these advanced copper smelting processes, from the ore material to the output of the anode plate, it must go through three processes of smelting, blowing and refining. The shortcomings of the traditional three-step process to complete the operation are: long process, large investment, low metal recovery rate, and high energy consumption. At the same time, since blowing and refining are carried out separately in different furnaces, the utilization rate of sulfur is low, the heat loss is large, the operating environment is poor, and the labor cost is high. Therefore, further research and development of a new pro...
