Problems solved by technology

However, the method of burning oxygen is usually used to open the discharge port, which seriously damages the refractory brick at the discharge port, which in turn adversely affects the service life of the smelting furnace
At the same time, the slag discharge process contains a certain amount of harmful gas, and the intermittent discharge of multiple ports increases the burden on the harmful gas treatment system, and the recovery rate of the flue gas is low, and the heat energy cannot be recycled.
[0007] Therefore, how to avoid the problem of long slag discharge time due to frequent opening and closing of the discharge port in order to replace the slag bag has become an important technical problem to be solved by those skilled in the art

Embodiment Construction

[0022] The invention provides a continuous discharge system for metallurgical slag, which does not need to frequently open and close the discharge port of the smelting furnace, and effectively shortens the discharge time of the slag.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Please refer to figure 1 , figure 1 It is a schematic diagram of a continuous discharge system for metallurgical slag in a specific embodiment of the present invention.

[0025] The metallurgical slag continuous dischar...

Abstract

The invention discloses a metallurgical slag continuous discharge system, which comprises a launder of which one end is in butt joint with a smelting furnace discharge outlet, a frame body, a buffer bag connected to the frame body by a hinged shaft and a driving device which is connected to the frame body and is used for driving the buffer bag to rotate around the hinged shaft, wherein the bufferbag is arranged below the launder, corresponds to the other end of the launder and is provided with an opening which takes the hinged shaft as a rotating shaft; and a circular slag receiving device is arranged below the opening. By the metallurgical slag continuous discharge system, the smelting furnace discharge outlet is not needed to be opened and closed frequently, so the slag discharging time is shortened effectively.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a continuous discharge system for metallurgical slag. Background technique [0002] The metallurgical industry is the pillar of the development of the national economy, and promoting the development of the metallurgical field is the fundamental task of promoting the modernization of our country. [0003] In the field of pyrometallurgy, a large amount of high-temperature molten slag will be produced when metal is smelted, and the slag contains a large amount of valuable metals. Take pyrometallurgy as an example: in the process of obtaining matte from sulfide ore smelting, the copper content in the slag exceeds 0.6%, or even reaches 2.5%. If it is discarded, it will cause a great waste of resources. The slag is recycled. [0004] In the existing slag recovery process, slow cooling of the slag followed by flotation is the most effective method. This process requires the slag...
