Description

Technical Field

[0001] The utility model relates to the technical field of copper smelting equipment, and more specifically to a granulation chamber used for granulating matte. Background Art

[0002] In the flash smelting of copper, the molten matte produced by the flash smelting furnace will first flow into the chute, and then flow into the granulation chamber through the chute. The granulation chamber needs to separate the matte particles and water. However, its separation structure is set on the scraper conveyor. The conveying of the matte particles by the scraper conveyor not only consumes electric energy for conveying, which reduces the discharge effect, but also has poor solid-liquid separation effect.

[0003] For example, announcement number CN219722803U discloses a granulation chamber for matte granulation, which includes a granulation chamber main body and multiple scraper conveyors. The scraper conveyors are inclined in the width direction of the scraper conveyors, and a drainage hole is provided at the lowest point of the bottom box wall that is inclined from top to bottom in the width direction of the scraper conveyors.

[0004] It can be seen from the above-mentioned public scheme that the matte particles and water fall on the scraper conveyor for solid-liquid separation, which not only has a poor separation effect, but also requires an electrically driven scraper conveyor, which consumes electricity and has a low discharge efficiency of the matte particles.

[0026] Example 2

[0027] See also Figure 1-3The granulation chamber for matte granulation comprises a granulation chamber body 1. An arc-shaped top plate 5 is arranged at one end of the granulation chamber body 1. An exhaust pipe 51 is fixedly sleeved on the top of the top plate 5 to facilitate the diversion and rapid discharge of steam. A molten matte chute 11, a high-pressure gas nozzle 12 and a high-pressure water spray pipe 13 are arranged on one side of the granulation chamber body 1. The molten matte chute 11, the high-pressure gas nozzle 12 and the high-pressure water spray pipe 13 belong to the prior art.
