Problems solved by technology

However, due to the problem of uneven material distribution in the feed box during the use of this nozzle, it will cause uneven mixing of gas particles in the flash furnace, unsaturated, and insufficient combustion, which will lead to high copper content in slag. The production decline, the increase of polluting gas and the occurrence of production safety and other issues

Embodiment Construction

[0041] Below in conjunction with embodiment technical solution of the present invention is made more specific description:

[0042] The present invention includes oxygen supply pipes 10 and dispersing air pipes 20 arranged vertically, overlapping tube cores, and arranged sequentially. The outer wall of the dispersing air pipe 20 is provided with a feeding box 30 , and the side of the feeding box 30 is There is a feeding port 31 that is inclined to feed downward, and the inside of the feeding box 30 is provided with a vertically arranged material distribution plate 32 that divides the feeding port 31 into a plurality of feeding ports. The width of the feeding port is The adjustment is realized by the rotation of the material distribution plate 32 , and the material feeding channel corresponding to the material feeding port guides the mineral material into the designated material cavity in the material feeding box 30 .

[0043] The present invention adjusts the width of each fee...

Abstract

The invention relates to a feed-adjustable premixed concentrate nozzle which comprises an oxygen supply pipe and a scattering air pipe, wherein the oxygen supply pipe and the scattering air pipe are vertically arranged and are sleeved in order, and the pipe cores of the oxygen supply pipe and the scattering air pipe are overlapped. The outer wall of the scattering air pipe is sleeved with a feed box, and a batch charging port used for inclined downward batch charging is formed in the side face of the feed box. Splitting plates are vertically arranged on the inner side of the feed box and are used for dividing the batch charging port into a plurality of batch charging branch ports, and the width of the batch charging branch ports is regulated by the rotation of the splitting plates. Batch charging channels corresponding to the batch charging branch ports lead mineral aggregates to the specified material chambers in the feed box. The width of all the batch charging branch ports is regulated by the rotation of the splitting plates, so that the batch charging amount of each batch charging branch port is controlled, and further the batch charging amount of the specified material chambers in the feed box can be controlled. The feed-adjustable premixed concentrate nozzle realizes uniform feeding on each point direction in a flash furnace and effectively solves the problem that the burning temperature in the flash furnace is unbalanced.

Description

technical field [0001] The invention belongs to the technical field of copper smelting, and in particular relates to a feed-adjustable premixing concentrate nozzle. Background technique [0002] Patent application 201610632799.5 discloses a vibrating premixed concentrate nozzle. The working process of the nozzle is: the concentrate enters through the feed box, the feed box and the distributor slices play the role of material distribution, and then the material is distributed through the dispersing cone. , mixed with various combustible and combustion-supporting gases such as process air, central oxygen, epoxy air, natural gas and other combustible and combustion-supporting gases by dispersing air and air regulating cone to improve the mixing effect of gas particles and achieve full combustion. However, due to the problem of uneven material distribution in the feed box during the use of this nozzle, it will cause uneven mixing of gas particles in the flash furnace, unsaturate...
