Description

Technical Field

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

[0002] The characteristics of large energy and ore resource consumption and resource intensiveness in the non-ferrous metal industry determine that the non-ferrous metal industry is one of the industries with the most conditions and potential for developing circular economy. Circular economy takes the efficient utilization and recycling of resources as the core, follows the principles of "reduce, reuse, recycle", and has the basic characteristics of "low consumption, low emission, high efficiency". Shifting from the "resource - product - waste" model to the "resource - product - renewable resource" new model is an economic growth model that conforms to the concept of sustainable development and is also a fundamental change to the traditional economic growth model of "mass production, mass consumption, and mass waste".

[0003] At present, copper-containing waste materials adopt the "blowing + electrolysis" process. Currently, most blowing furnaces use horizontal cylindrical tanks. The copper-containing waste materials are fed into the cylindrical tank for blowing, and crude copper is produced through the processes of slag formation, slag discharge, and copper discharge. The cylindrical tank rotates centering around a horizontal central axis at a fixed position. Due to the cylindrical structure and the fixed horizontal central rotating shaft of the horizontal cylindrical tank, the pitching angle of the horizontal central axis of the horizontal cylindrical tank cannot be adjusted during the slag discharge and copper discharge processes, so precise operations on the speed and discharge amount of slag discharge and copper discharge cannot be carried out. The crude copper produced has a high impurity content and low production efficiency. Summary of the Invention

[0004] Based on this, the present invention provides a metal copper production system and process based on blowing and electrolysis processes to realize the adjustment of the pitching angle of the central axis of the furnace body during the slag discharge and copper discharge processes, so as to perform precise operations on the speed and discharge amount of slag discharge and copper discharge, effectively control the impurity content of the produced crude copper, and improve production efficiency.

[0005] To achieve the above object, in a first aspect, the present invention provides a metal copper production system based on blowing and electrolysis processes, including: A spherical furnace, which is rotatably arranged on a base around its central axis, and the pitching angle of the central axis of the spherical furnace is adjustable. The input port and the output port are oppositely arranged at both ends of the central axis of the spherical furnace; A raw material input unit, which is arranged outside the input port of the spherical furnace and is used to convey copper-containing raw materials, fuels, and auxiliary materials to the input port of the spherical furnace; A crude copper output unit, which is arranged outside the output port of the spherical furnace and is used to receive the crude copper discharged from the output port of the spherical furnace; An electrolytic cell, which is connected to the crude copper output unit and receives the output crude copper for electrolysis; A control unit, which is electrically connected to the spherical furnace, the raw material input unit, the crude copper output unit and the electrolytic cell by electrical signals.

[0006] Furthermore, the spherical furnace is provided with an input neck body and an output neck body which are arranged oppositely and extend outward along the central axis. The input port is arranged at the front end of the input neck body and communicates with the front part of the inner cavity of the spherical furnace, and the output port is arranged at the front end of the output neck body and communicates with the rear part of the inner cavity of the spherical furnace.

[0007] Furthermore, an annular bracket is arranged between the base and the spherical furnace. The annular bracket is provided with an input seat body and an output seat body which are arranged longitudinally oppositely. The input neck body of the spherical furnace is rotatably arranged in the central hole of the input seat body, and the output neck body is rotatably arranged in the central hole of the output seat body. A toothed structure is circumferentially arrayed on the outer circumference of the input neck body and / or the output neck body. The input seat body and / or the output seat body is provided with a first rotating mechanism. The output end of the first rotating mechanism is meshed with the toothed structure through a gear. The control unit is electrically connected to the first rotating mechanism to drive the first rotating mechanism to drive the spherical furnace to rotate around its central axis during the melting and discharging of crude copper.

[0008] Furthermore, the outer part of the annular bracket is provided with transverse rotating shafts which are arranged transversely oppositely and extend outward along the axis. The base is provided with support ear seats which are arranged transversely oppositely and protrude upward. The transverse rotating shafts are rotatably arranged on the support ear seats. A second rotating mechanism which is drivingly connected to the transverse rotating shafts is arranged on the base. The control unit is electrically connected to the second rotating mechanism to drive the annular bracket to rotate around the transverse rotating shafts through the second rotating mechanism, so as to adjust the pitching angle of the central axis of the spherical furnace.

[0009] Furthermore, an input end cover is hinged to the outside of the input seat body through a top hinge shaft. A third rotating mechanism is drivingly connected to the input end cover. The control unit is electrically connected to the third rotating mechanism and is used for controlling the input end cover to rotate forward around the hinge shaft to be buckled to the input port or rotate reversely to be opened. When the input end cover is buckled to the input port, the input end cover is in sliding sealing fit with the input port. An output end cover is hinged to the outside of the output seat body through a top hinge shaft. A fourth rotating mechanism is drivingly connected to the output end cover. The control unit is electrically connected to the fourth rotating mechanism and is used for controlling the output end cover to rotate axially around the hinge shaft to be buckled to the output port or rotate reversely to be opened. When the output end cover is buckled to the output port, the output end cover is in sliding sealing fit with the output port. The control unit includes a weight monitor arranged on the base. The weight monitor monitors the weight change of the spherical furnace in real time and transmits it to the control unit. The control unit controls the action of the second rotating mechanism according to the weight monitoring value. When the weight of the spherical furnace exceeds the set range, it drives the annular bracket to rotate around the transverse rotating shaft to control the output port of the central axis of the spherical furnace to pitch downward and control the output end cover to be opened, so as to discharge the crude copper and reduce the weight of the spherical furnace.

The air input pump is connected to one of the input end cover and the output end cover, and the air output pump is connected to the other of the input end cover and the output end cover. The control unit is electrically connected to the air input pump and the air output pump.

[0011] Further, the control unit includes a temperature monitor disposed on the input end cover and / or the output end cover. The temperature monitor monitors the temperature inside the spherical 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. When the temperature monitoring value reaches the upper limit of the set range, the control unit controls the air input pump to reduce the amount of air input into the spherical furnace. When the temperature monitoring value reaches the lower limit of the set range, the control unit controls the air input pump to increase the amount of air input into the spherical furnace.

[0012] Further, the control unit includes an in-furnace air pressure monitor disposed on the input end cover and / or the output end cover. The in-furnace air pressure monitor monitors the air pressure inside the spherical furnace in real time and transmits it to the control unit. The control unit controls the displacement of the air output pump according to the air pressure inside the spherical furnace. When the monitored value of the air pressure inside the spherical furnace reaches the upper limit of the set range, the control unit controls the displacement of the air output pump to be greater than that of the air input pump to reduce the air pressure inside the spherical furnace. When the monitored value of the air pressure inside the spherical furnace reaches the lower limit of the set range, the control unit controls the displacement of the air output pump to be less than that of the air input pump to increase the air pressure inside the spherical furnace.

[0018] Embodiment 1: As Figures 1 to 11As shown in the figure, the present invention provides a metallic copper production system based on the blowing and electrolysis processes, which includes a spherical furnace 3, a raw material input unit, a crude copper output unit, an electrolytic cell, and a control unit. The spherical furnace 3 is rotatably arranged on a base 1 around its central axis, and the pitching angle of the central axis is adjustable. The input port and the output port are oppositely arranged at both ends of the central axis of the spherical furnace 3. The raw material input unit is arranged outside the input port of the spherical furnace 3 and is configured to convey copper-containing raw materials, fuel, and auxiliary materials to the input port of the spherical furnace 3. The crude copper output unit is arranged outside the output port of the spherical furnace 3 and is configured to receive the crude copper discharged from the output port of the spherical furnace 3. The electrolytic cell is connected to the crude copper output unit to receive the output crude copper and perform electrolysis. The control unit is electrically connected to the spherical furnace 3, the raw material input unit, the crude copper output unit, and the electrolytic cell by electrical signals.

[0019] It should be noted that for the metallic copper production system based on the blowing and electrolysis processes provided by the present invention, the blowing furnace is set as the spherical furnace 3. The input port and the output port are oppositely arranged at both ends of the central axis of the spherical furnace 3. The spherical furnace rotates around the central axis and the pitching angle is adjustable. During the slag discharging and copper discharging processes, the pitching angle of the central axis can be precisely controlled, so as to precisely operate the speed and discharge amount of slag discharging and copper discharging, making the produced crude copper have a low impurity content, effectively improving the production efficiency, and reducing the workload of electrolysis in the electrolytic cell.

[0020] As Figure 3 shown in the figure, during the implementation process, the spherical furnace 3 is provided with an input neck body 31 and an output neck body 32 that are oppositely arranged and extend outward along the central axis. The input port is arranged at the front end of the input neck body 31 and is communicated with the front part of the inner cavity of the spherical furnace 3. The output port is arranged at the front end of the output neck body 32 and is communicated with the rear part of the inner cavity of the spherical furnace 3.

[0021] As Figures 2 - 5 shown in the figure, an annular bracket 2 is arranged between the base 1 and the spherical furnace 3.

[0023] Furthermore, the control unit includes a weight monitor provided on the base 1. The weight monitor monitors the weight change of the spherical furnace 3 in real time and transmits it to the control unit. The control unit controls the operation of the second rotating mechanism 61 according to the weight monitoring value. When the weight of the spherical furnace 3 exceeds the set range, it drives the annular support 2 to rotate around the transverse rotating shafts 21 to control the downward pitch of the output port of the central axis of the spherical furnace 3 and control the opening of the output end cover 51 to discharge the blister copper and reduce the weight of the spherical furnace 3.

[0024] It should be noted that an annular support 2 is provided between the base 1 and the spherical furnace 3. The annular support 2 is rotatably connected to the base 1 through the transverse rotating shafts 21. The spherical furnace 3 is arranged on the longitudinally opposite input seat body 22 and output seat body 23 of the annular support 2. During the smelting process of copper-containing waste in the spherical furnace 3, the rotation of the spherical furnace around the central axis and the adjustment of the pitching angle of the central axis are carried out separately, and the two do not interfere with each other. While being able to dynamically adjust the pitching angle of the central axis of the spherical furnace, the spherical furnace rotates around the central rotating shaft to uniformly mix the copper-containing materials in the furnace during the smelting process, realize dynamic and high-efficiency slag making, improve the slag discharge rate, and effectively reduce the impurity content of the blister copper.

A third rotating mechanism 42 is drivingly connected to the input end cover 41. The control unit is electrically connected to the third rotating mechanism 42 and is configured to control the input end cover 41 to rotate forward around the hinge shaft to buckle to the input port or rotate backward to open. When the input end cover 41 buckles to the input port, the input end cover 41 is in sliding sealing fit with the input port.

The control unit is electrically connected to the fourth rotating mechanism 52 and is configured to control the output end cover 51 to rotate forward around the hinge shaft to buckle to the output port or rotate backward to open. When the output end cover 51 buckles to the output port, the output end cover 51 is in sliding sealing fit with the output port.

[0028] Furthermore, the control unit includes a temperature monitor arranged on the input end cover 41 and / or the output end cover 51, and the temperature monitor monitors the temperature in 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.

[0029] Furthermore, the control unit includes a furnace pressure monitor arranged on the input end cover 41 and / or the output end cover 51, the furnace pressure monitor monitors the furnace pressure in real time and transmits it to the control unit, the control unit controls the air output pump displacement according to the furnace pressure, when the furnace air pressure monitoring value reaches the upper limit of the set range, controls the air output pump displacement to be greater than the air input pump displacement to reduce the furnace pressure, and when the furnace air pressure monitoring value reaches the lower limit of the set range, controls the air output pump displacement to be less than the air input pump displacement to increase the furnace pressure.

[0031] Embodiment 2: like Figure 12 As shown, the present invention provides a metal copper production process based on blowing and electrolysis process, comprising: S100. Raw material input: The third rotating mechanism 42 drives the input end cover 41 to open, and the raw material input unit feeds copper-containing raw materials, fuel, and auxiliary materials into the furnace through the input port. The first rotating mechanism 71 drives the spherical furnace 3 to rotate for mixing the copper-containing raw materials, fuel, and auxiliary materials. S200. Smelting: The input end cover 41 and the output end cover 51 are in a buckled state. The fuel burns to smelt the copper-containing raw materials. The first rotating mechanism 71 drives the spherical furnace 3 to rotate for mixing the copper-containing raw materials, fuel, and auxiliary materials during the smelting process. The air input pump and the air output pump conduct air transportation in the furnace. S300. Slag discharging and copper discharging: The fourth rotating mechanism 52 drives the output end cover 51 to open, and the second rotating mechanism 61 drives the output port of the spherical furnace 3 to be adjusted downward in a prone position, and slag discharging and then discharging the crude copper to the crude copper output unit are carried out successively. S400. Electrolysis of crude copper: The electrolysis unit receives the crude copper discharged from the crude copper output unit and electrolyzes to produce electrolytic copper.

[0032] It should be noted that the provided production process of metallic copper based on the blowing and electrolysis processes is conducive to achieving uniform mixing of the materials in the furnace in the front-back direction during the slag-making process, efficiently making slag, and realizing the adjustment of the pitching angle of the central axis of the furnace body during the slag discharging and copper discharging processes, so as to achieve precise operation of the speed and discharge amount of slag discharging and copper discharging, effectively control the impurity content of the produced crude copper, and improve production efficiency.

[0033] Further explanation, in some specific embodiments, copper sludge, lead matte, copper-lead slag, nickel electrolytic anode sludge, slag dressing concentrate, pyrite, and self-produced copper-containing materials are mixed and proportioned together, and then grabbed into the bunker by a grab bridge crane, transported to the electronic belt scale for weighing through a feeder, then transported to a belt conveyor, and then transferred to a mobile belt conveyor and transferred to a converter for oxygen-enriched smelting. Using natural gas as the heat source, at a temperature of 1050 - 1100 °C, most of the lead and copper are reduced to copper and lead, realizing the separation of the slag and the metal phase. The lead alloy is enriched and sinks to the bottom, and the copper alloy is discharged and transferred to the spherical furnace for blowing, and then cast into crude copper after being discharged.

[0034] The spherical furnace operates intermittently. Each blowing cycle is divided into three stages: slag-making, slag discharging, and copper discharging. The task of blowing during the slag-making period is to oxidize and make slag a small amount of Cu2S and other active metal impurities in the copper alloy, remove sulfur and active metals such as iron, and produce crude copper with a Cu grade of about 98.5%. Iron mainly enters the slag in the form of FeO•SiO2 to be removed, and lead mainly enters the flue dust in the form of PbO.

[0035] 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 them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
