Problems solved by technology

However, when the concentrate material is delivered to the concentrate nozzle and falls, when the concentrate material accumulates toward the inner wall of one side or both sides of the water-cooling sleeve, it only passes through the dispersing cone at the lower end of a distributor and the dispersing wind. Blowing effect, it is also difficult to achieve the effect of uniform material distribution

Embodiment Construction

[0008] In conjunction with accompanying drawing, the present invention will be further described:

[0009] A concentrate nozzle, comprising a water-cooling sleeve 10, a distributor 30 is arranged inside the water-cooling sleeve 10, a rotary paddle 20 is arranged on the distributor 30 where the discharge end of the lower pipe end of the water-cooling sleeve 10 is located, and a driving mechanism The distributor 30 is driven to rotate to provide kinetic energy for dispersion to the passing materials.

[0010] The rotary paddle 20 provided at the lower part of the distributor 30, when feeding the concentrate material, the material is delivered from the upper pipe end of the water-cooled casing 10, and the material falls under its own gravity, and the centrifugal force formed by the rotary paddle 20 makes The materials are dispersed, so that the concentrate materials are in a uniform suspension state. After entering the flash furnace, the gas phase and the solid phase are fully mi...

Abstract

The invention discloses a jet nozzle of concentrate used in a copper smelting flash furnace. The jet nozzle comprises a distributor arranged inside a water-cooled sleeve, wherein rotary shifting sheets are arranged on the distributor located at the material-outlet end of a lower tube end of the water-cooled sleeve, and a driving mechanism drives the distributor to rotate to provide kinetic energy for dispersion to the passing material; when the concentrate material is delivered toward the jet nozzle of concentrate, the material enters a passage formed between the distributor and the water-cooled sleeve, falls under the action of gravity, acquires kinetic energy under the action of the rotary shifting sheets so that the concentrate material can evenly fall, be dispersed and be fully mixed with peripheral process air and the reaction effect of evenly mixed concentrate material in a reaction tower can be further ensured.

Description

technical field [0001] The invention relates to a copper smelting flash furnace, in particular to a copper smelting flash furnace concentrate nozzle. Background technique [0002] The flash smelting process is to fully mix the dried powdery mixed charge, oxygen-enriched air and auxiliary fuel (heavy oil, pulverized coal, natural gas, etc.) Into the reaction tower of the flash furnace, the charge is suspended in the reaction tower and gradually falls down. At the same time, under the action of high temperature, the physical and chemical reactions of gas phase and solid phase are carried out, so as to smelt copper concentrate. Since the flash furnace is a suspension smelting system, the charge reacts quickly after entering the reaction tower, and the reaction is completed in an average of 3 to 5 seconds. Therefore, the uniformity of charge ejected from the water-cooled casing and the mixing state of charge and process air play a key role in the reaction efficiency. [0003] ...
