Embodiment Construction

[0027] preferred embodiment, such as Figure 1 to Figure 8 As shown, the oxygen-enriched smelting furnace for processing low-grade polymetallic materials provided by the present invention includes a steel structure frame body 1, a furnace hearth 2 arranged in sequence from bottom to top, a copper water jacket furnace wall 3, a hanging Water jacket 4. The steel frame body 1 includes a support frame 11 for supporting the furnace hearth 2 and the copper water jacket furnace wall 3 at the bottom and a hanger 12 for hanging the hanging steel water jacket 4 at the upper end to bear all the loads produced by the furnace body. The outer wall of the copper water jacket furnace wall 3 has a fixed frame 7, and the fixed frame 7 is fixed by a jack 8 and a support frame 11. Both the hanger 12 and the support frame 11 are made of H-shaped steel, and the hanger 12 and the support frame 11 are connected by detachable bolts.

[0028] Hearth 2 includes masonry 22 , H-shaped steel hoop 21 and ...

Abstract

The invention discloses an oxygen-enriched smelting furnace for treating a low-grade multi-metal material. The oxygen-enriched smelting furnace comprises a furnace hearth, a copper water jacket furnace wall and a hanging-type steel water jacket which are sequentially arranged from bottom to top, wherein a steel structural frame is arranged on the peripheries of the furnace hearth, the copper water jacket furnace wall and the hanging-type steel water jacket, the furnace hearth is positioned on a skeleton of the bottom surface of the steel structural frame, a fixed frame for connecting with the steel structural frame is arranged on the outer wall of the copper water jacket furnace wall, and the hanging-type steel water jacket is hung at the upper end of the steel structural frame; the copper water jacket furnace wall comprises a plurality of layers of copper water jackets, and the bottom of the copper water jacket at the bottommost layer is provided with an oxygen spray nozzle and a punching slagging device; the upper end of the hanging-type steel water jacket is provided with a flue hole and a charging hole which are communicated with the hanging-type steel water jacket and used for discharging smoke and charging. The left and right deformation of the water jacket is avoided due to the structure of the hanging-type steel water jacket, the defects that a slag hole water jacket is prone to leak, and the furnace shutdown is needed during the replacement of the water jacket are overcome due to the structure of the punching slagging device, and the safety using property of the oxygen-enriched smelting furnace is improved. The oxygen-enriched smelting furnace has the characteristics that during smelting, the amount of flue gas is small, little heat is taken away by flue gas, the temperature of a molten pool is high, and lead and zinc are easy to volatile.

Description

[0001] technical field [0002] The invention relates to a smelting furnace suitable for smelting non-ferrous metals, which is used for oxygen-enriched smelting of various metal materials containing copper, lead, zinc, etc., to generate copper matte or rough lead, and to recover valuable metals. Background technique [0003] With the increasingly stringent environmental protection policies in my country and the implementation of access conditions for copper, lead, zinc and other industries, the demand for new non-ferrous smelting processes that meet environmental protection requirements and low production costs has become increasingly prominent. At the same time, with the dwindling of high-grade primary ore resources, new processing requirements are put forward for materials with low grades, difficult to handle by traditional processes, and complex polymetallic materials. It is required that the new smelting process is suitable for recycling a variety of valuable metals, and ...
