Description

Technical Field

[0001] The present invention relates to the technical field of metallic copper production technology, and in particular to a metallic copper production system and process based on blowing and electrolysis processes. Background Art

[0002] The nonferrous metals industry's high energy and mineral resource consumption and resource-intensive nature make it one of the industries with the greatest potential and potential for developing a circular economy. The circular economy centers on the efficient and cyclical use of resources, adheres to the principles of "reduction, reuse, and resource utilization," and features "low consumption, low emissions, and high efficiency." The shift from a "resources-products-waste" model to a "resources-products-recycled resources" model is an economic growth model consistent with the concept of sustainable development and represents a fundamental shift from the traditional economic growth model of "mass production, mass consumption, and mass waste."

[0003] At present, copper-containing waste adopts the "blowing + electrolysis" process. The current blowing furnace mostly adopts a horizontal cylindrical tank body. The copper-containing waste is fed into the cylindrical tank body for blowing. After the processes of slag making, slag tapping and copper tapping, crude copper is produced. The cylindrical tank body rotates around the horizontal center axis at a fixed position. Due to the columnar structure and the fixed horizontal center axis of the horizontal cylindrical tank body, the pitch angle of the horizontal center axis of the horizontal cylindrical tank body cannot be adjusted during the slag tapping and copper tapping process, thereby unable to perform precise operation of the slag tapping and copper tapping speed and discharge amount. The crude copper produced has high impurity content and low production efficiency. Summary of the Invention

[0004] Based on this, the present invention provides a metallic copper production system and process based on blowing and electrolysis processes, so as to realize the adjustment of the pitch angle of the central axis of the furnace body during the slag and copper tapping processes, thereby accurately controlling the speed and discharge amount of slag and copper tapping, effectively controlling the impurity content of the produced crude copper, and improving production efficiency.

[0005] In order to achieve the above objectives, in a first aspect, the present invention provides a copper metal production system based on a blowing and electrolysis process, comprising:

The control unit controls the action of the second rotating mechanism 61 according to the weight monitoring value.

[0056] Furthermore, the control unit includes a temperature monitor provided on the input end cover 41 and / or the output end cover 51, and the temperature monitor monitors the temperature inside the furnace in real time and transmits it to the control unit. The control unit controls the displacement of the air input pump according to the temperature monitoring value, and controls the air input pump to reduce the amount of air input into the spherical furnace 3 when the temperature monitoring value reaches the upper limit of the set range, and controls the air input pump to increase the amount of air input into the spherical furnace 3 when the temperature monitoring value reaches the lower limit of the set range.

[0057] Furthermore, the control unit includes a furnace pressure monitor arranged on the input end cover 41 and / or the output end cover 51, and the furnace pressure monitor monitors the furnace pressure in real time and transmits it to the control unit.

[0059] Example 2:

[0060] like Figure 12 As shown, the present invention provides a copper metal production process based on blowing and electrolysis processes, comprising:

[0061] S100 raw material input: the third rotating mechanism 42 drives the input cover 41 to open, the raw material input unit is fed into the furnace through the input port copper raw material, fuel and auxiliary materials, the first rotating mechanism 71 drives the spherical furnace 3 to rotate, the copper raw material, fuel and auxiliary materials are mixed;

[0062] S200 smelting: the input end cap 41 and the output end cap 51 are in a buckled state, the fuel is burned to smelt the copper-containing raw material, the first rotating mechanism 71 drives the spherical furnace 3 to rotate, the copper-containing raw material, fuel and auxiliary materials are mixed during the smelting process, the air input pump and the air output pump are used to transport air into the furnace;

[0063] S300 slag and copper: the fourth rotary mechanism 52 drives the output cover 51 to open, the second rotary mechanism 61 drives the output port of the spherical furnace 3 to bend downward, successively slag and discharge blister copper to the blister copper output unit;

[0064] S400. Electrolysis of blister copper: The electrolysis unit receives the blister copper discharged from the blister copper output unit and electrolyzes it to generate electrolytic copper.

[0065] It should be noted that the provided metallic copper production process based on blowing and electrolysis processes is conducive to achieving uniform mixing of materials in the front and rear directions of the furnace and efficient slag formation during the slag making process, and realizing adjustment of the pitch angle of the central axis of the furnace body during the slag and copper tapping processes, thereby achieving precise operation of the slag and copper tapping speed and discharge volume, effectively controlling the impurity content of the produced crude copper, and improving production efficiency.

[0066] Further, in some specific embodiments, copper sludge, lead matte, copper-lead slag, nickel electrolytic anode slime, slag concentrate, pyrite, and self-produced copper-containing materials are mixed and batched, then grabbed by a grab bridge crane and loaded into a silo. The materials are then weighed by a feeder and transported to an electronic belt scale before being transported to a belt conveyor. From there, they are transferred to a mobile belt conveyor and fed into a converter for oxygen-enriched smelting. Using natural gas as the heat source, at temperatures of 1050-1100°C, the lead and copper are largely reduced to copper and lead, achieving separation of the slag and metal phases. The lead alloy concentrates and sinks to the bottom, while the copper alloy is discharged and transferred to a spherical furnace for blowing, where it is cast into blister copper.

[0067] The spherical furnace operates intermittently, with each blowing cycle divided into three stages: slagging, slagging, and copper tapping. During the slagging stage, the blowing process oxidizes the small amount of Cu2S and other active metallic impurities in the copper alloy to form slag, removing active metals such as sulfur and iron, and producing blister copper with a Cu grade of approximately 98.5%. Iron is primarily removed in the form of FeO•SiO2 in the slag, while lead, mostly in the form of PbO, enters the dust.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present invention. They should all be included in the scope of the technical solutions claimed for protection by the present invention.
