Copper smelting furnace

Abstract

The invention provides a copper smelting furnace. Smoke generated by feeding is effectively restrained by a furnace body, meanwhile, feeding openings are not prone to being caked or deformed, and reaction efficiency is improved. To achieve the aim, according to the technical scheme, the copper smelting furnace comprises the furnace body, and is characterized in that the feeding openings in the furnace body are located on the upper portion of the furnace body. According to the technical scheme, the feeding openings are formed on the upper portion of the furnace body, so that materials freely fall into the furnace through the feeding openings, the situations of material flying are reduced, materials capable of generating smoke can be reduced, and correspondingly the smoke rate is lowered; in addition, due to the fact that the temperature of smoke on the upper portion of the furnace body is high, the feeding openings are not prone to being caked or deformed after being formed on the upper portion of the furnace body.

Description

technical field [0001] The invention relates to the field of copper smelting, in particular to a copper smelting furnace. Background technique [0002] Such as figure 1 As shown, the Noranda furnace is a horizontal cylindrical rotatable furnace body 10, which is a typical molten pool smelting equipment. The cylinder body is made of 50mm thick 16Mn steel and is lined with magnesia-chrome refractory bricks. , The furnace body 10 is supported on the support wheel 20, driven by the motor 30, it can rotate around the furnace body axially within a certain range. The Noranda furnace is a furnace body structure widely used in the existing copper smelting process. The Noranda furnace is roughly divided into a reaction zone I and a precipitation zone II along the length of the furnace body 10, wherein the reaction zone I is close to the feeding port 11, and the precipitation zone Zone II is close to the discharge port at the tail end. During smelting, the prepared copper concentrate...

AI Technical Summary

Problems solved by technology

The furnace body structure has the following technical defects because the feeding port is located at the end of the furnace body: 1. The material needs to be thrown into the furnace through the throwing machine, and the material is flying, and the amount of smoke and dust is large; 2. The throwing material is concentrated and cannot be thrown into the reaction All areas in zone I have low reaction efficiency; 3. The feeding port is easy to coke, and it takes a certain amount of time to clean it, which affects the operation rate. In addition, the feeding port is seriously deformed in the later stage of production, and the throwing efficiency is not high. There are many materials leaking and the working environment is poor.
