Horizontal type smelting furnace

Abstract

A horizontal melting furnace comprises a furnace body support and a furnace body, wherein a housing, a heat insulation layer and a fireproof layer are sequentially arranged on the furnace body from outside to inside; the tail end of the furnace body is connected with a flue; the head of the furnace body is communicated with a pulverized coal inlet; the furnace body is horizontally arranged on the furnace body support; the horizontal melting furnace also comprises a rotating mechanism and a tilting mechanism; the rotating mechanism is arranged between the furnace body; and the tilting mechanism is arranged on the bottom of the furnace body support. The horizontal melting furnace solves the technical problems existing in the prior melting furnace in the background technology, such as poor heat transfer and mass transfer condition in the furnace, difficult material discharge, and environment pollution caused by escaped gas. The horizontal melting furnace has the advantages of high melting quality, simple discharge and no environment pollution.

Description

technical field [0001] The invention relates to a smelting furnace, in particular to a horizontal smelting furnace applied to copper-lead-zinc mixed concentrate. Background technique [0002] Mineral resources are an important material basis for national economic construction. Although my country's main mineral resource reserves are relatively rich, due to continuous development, the remaining reserves are rapidly decreasing, and high-quality mineral deposits are on the verge of exhaustion. In recent years, my country's geological exploration departments have successively discovered and verified copper, lead, zinc, silver polymetallic complex sulfide deposits with large reserves and wide distribution in the Sanjiang area of ​​southwest China. There are currently two processing methods for mixed concentrates: hydrometallurgical method and pyrometallurgical method in metallurgy. Among the pyrometallurgical processing methods, short kiln smelting is more common. [0003] At pr...
