Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a slag removal and degassing device for copper refining. Background Technology

[0002] Existing slag and degassing devices for copper refining are mainly used to remove gaseous and solid impurities generated during the copper refining process by the reaction of deoxidizers and copper refining agents with the molten copper. If these impurities are not removed, they will affect the purity of the copper and the quality of the final product. However, these devices lack components for treating waste gas. The direct emission of untreated high-temperature waste gas may lead to an increase in the emission of harmful gases (such as sulfides and nitrogen oxides), negatively impacting the ecosystem and affecting the surrounding environment and residents' health. For example, Chinese patent discloses a "Slag and Degassing Device for Copper Refining," application number "20..." 2223372732.2” This device includes a processing box with a processing guide channel inside. A feeding mechanism is installed at the top of the processing box. From one end of the feeding mechanism to the other end, an agitator and a slag and gas removal mechanism are arranged in sequence. This improves the overall slag and gas removal effect and practicality of the copper refining device. However, it does not have a component for treating waste gas when in use. The high-temperature waste gas is directly emitted without treatment, which may lead to an increase in the emission of harmful gases (such as sulfides, nitrogen oxides, etc.), which will have a negative impact on the ecosystem and affect the surrounding environment and residents' health.
