Device for increasing quantity of ores treated by boiling furnace

Abstract

The invention discloses a device for increasing a quantity of ores treated by a boiling furnace. The device consists of a roots blower, a furnace bottom wind pipe, the boiling furnace, a high-pressure wind pipe and an air storage tank; the roots fan is communicated with the boiling furnace by the furnace bottom wind pipe; a wind cap is arranged in the boiling furnace for covering the bottom of the boiling furnace, and is provided with through holes in the periphery; one end of the high-pressure wind pipe is communicated with the air storage tank, and the other end extends in the boiling furnace; and an outlet end is arranged at the wind cap. As the number of small holes of the wind cap is reduced, and the size of the small holes is reduced, the air speed of the small holes of the wind cap is effectively accelerated, and the boiling effect of the boiling furnace is effectively improved; and meanwhile, high-pressure wind is added on a discharge box, so that the furnace bottom pressure of the boiling furnace is effectively increased, the slag burning discharge is inhibited, the roasting time of materials in the furnace is prolonged, and the treatment quantity of the boiling furnace is effectively increased. The device is simple in structure, stable in operation and high in adaptability, and effectively improves the equipment efficiency.

Description

technical field

[0001] The invention relates to the technical field of mechanical equipment in the smelting industry, in particular to a device for increasing the amount of ore processed by a fluidized fluidized furnace. Background technique

[0002] The boiling furnace of the roasting system is used for pretreatment of complex gold concentrate with high sulfur content and arsenic. Due to the complex and changeable composition of the raw ore, especially the change of mineral specific gravity, it is difficult to control the bottom pressure of the fluidized furnace, which seriously affects the roasting effect and processing capacity. In addition, the design Due to the limited scale, the processing ore capacity of the fluidized fluidized furnace has not been effectively improved. Contents of the invention

[0003] Aiming at the deficiencies of the prior art, the present invention proposes a device for increasing the amount of ore processed by a fluidized fluidized furnace, wh...

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0014] Such as figure 1 A device for increasing the amount of ore processed in a fluidized fluidized furnace is shown, which is sealed and connected by a Roots blower 1 and a furnace bottom air pipe 2. There are four small holes of ∮=6mm around. One end of the high-pressure air pipe 6 extends into the discharge box 5 and goes down to a certain height.

[0015] When in use, because the number of small holes in the air cap 4 is reduced and the hole diameter becomes smaller, the gas velocity of the small holes at the bottom of the furnace will be further increased under the same furnace air volume, and the boiling effect of materials in the fluidized fluidized furnace 3 can be improved, which can effectively increase t...
