Description

Technical Field

[0001] The invention relates to the technical field of anode furnaces, in particular to an anode furnace used for oxidative copper smelting. Background Art

[0002] Anode furnace, also known as rotary refining furnace, is a device used for refining liquid crude copper.

[0003] At present, in the process of oxidative blowing copper smelting, the copper raw materials are usually placed in an anode furnace, which is used to melt the copper raw materials and form a solution. Then, an air duct is inserted from the top of the anode furnace. The air duct consists of an inner tube and an outer stainless steel tube. The inner tube is extended into the solution and oxygen is introduced into the solution. The oxygen reacts with FeS in the solution to generate iron oxide, i.e., iron slag.

[0004] However, although the introduction of a large amount of oxygen can ensure that oxygen reacts with FeS in the solution to form iron slag, there will be a local excess of oxygen near the output end of the inner tube, and there will be a shortage of oxygen at the same time in the area far from the output end of the inner tube. When there is excess oxygen, a certain amount of copper will be oxidized and then discharged as waste together with the iron slag, affecting the copper production; insufficient oxygen will prevent some FeS in the solution from completely reacting with oxygen, resulting in the inability to completely extract FeS from the solution.

[0017] Wherein, the first sub-tube has a collecting cavity which is interconnected with the first through hole.

[0018] Furthermore, the bottom size of the second sub-casing extends outward from large to small.

[0019] Furthermore, the collecting sleeve also includes a plurality of connecting rods and lifting connectors;

[0020] The lifting connector is connected to the end of the first sub-casing through a plurality of connecting rods, and the plurality of connecting rods are arranged at intervals along the end of the casing to form a lifting area between the plurality of connecting rods for the composite transmission pipe to pass through;

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In an anode furnace used for copper oxidation smelting provided by the present invention, a plurality of composite transmission tubes and a plurality of collecting sleeves are arranged on the anode furnace body, and each two collecting sleeves in the plurality of composite transmission tubes are used to be detachably connected to the opposite sides of the anode furnace body, and each collecting sleeve is respectively lifted and arranged on each composite transmission tube, so that when the reaction gas is introduced into the melt, the composite transmission tube is used to transmit the reaction gas, and the reaction gas is a high-pressure reaction gas with a certain pressure. Each two composite transmission tubes are detachably connected to the opposite sides of the anode furnace body, so that the high-pressure reaction gas can be output from two sides of the anode furnace body, so that the melt in the anode furnace body can be output in two directions and react with the corresponding melt, thereby shortening the melt and the reaction gas. The reaction time of the body is shortened, and high-pressure reaction gases of the same pressure are output through the corresponding output ends of the two composite transmission pipes, and the high-pressure reaction gases impact each other in the anode furnace body to form a composite reaction gas.

The high-pressure characteristic of the reaction gas in the present invention is utilized to enable the reaction gas to be transmitted to the middle of the anode furnace body, and the composite reaction gas is formed by the mutual impact of the two high-pressure gases. The composite reaction gas is used to react with the solution in the middle, thereby solving the technical problems in the prior art that a certain amount of copper is oxidized and part of FeS cannot react completely with oxygen.

[0034] 2. Since iron oxide, i.e., iron slag, is generated during the reaction of the reaction gas with the solution, and the iron slag floats on the surface of the solution, in the prior art, the anode furnace body is usually turned sideways to allow the iron slag to be discharged from the anode furnace body along with the solution. However, the operation mode of the prior art leads to the problem that the iron slag cannot be completely cleaned from the surface of the solution. In the present invention, a collecting sleeve arranged on each composite transmission pipe is lifted and lowered to drive the collecting sleeve to move up and down, so that the collecting sleeve is located below the liquid surface of the solution. The movement trajectory of the fluid is utilized to collect the floating medium floating on the surface of the solution along with the flow of the solution in the collecting sleeve, thereby solving the problem that the operation of cleaning the iron slag is difficult and the problem that the iron slag cannot be completely cleaned from the surface of the solution is solved.

[0049] See also Figure 1-Figure 10 As shown, the present invention provides an anode furnace for oxidative copper smelting, comprising a plurality of composite transmission tubes 100, a plurality of collecting sleeves 200 and an anode furnace body 300 for accommodating copper solution. In the present embodiment, the anode furnace body 300 is a device for smelting blister copper, mainly smelting blister copper into solution. It should be noted that the components constituting the anode furnace body 300 are conventional prior art in the field, and therefore are not specifically described herein.

[0050] Specifically, in this embodiment, every two collecting sleeves 200 in the plurality of composite transmission tubes 100 are used to be detachably connected to opposite sides of the anode furnace body 300, and the output end of each composite transmission tube 100 is used to extend into the melt and transmit the high-pressure reaction gas toward the melt;

[0051] The high-pressure reaction gases of the same pressure are respectively outputted through the corresponding output ends of the two composite transmission pipes 100, and impact each other in the anode furnace body 300 to form a composite reaction gas, and the high-pressure reaction gas and the composite reaction gas react with the reaction medium in the melt to form a floating medium on the surface of the melt;

[0052] Among them, each collecting sleeve 200 is respectively raised and lowered on each composite transmission pipe 100. By driving each collecting sleeve 200 to rise and fall relative to each composite transmission pipe 100, the collecting end of the collecting sleeve 200 is located below the liquid surface of the melt to collect the floating medium in the collecting sleeve 200.

[0053] For a better understanding of this case, please refer to Figure 2-Figure 4 As shown, when the reaction gas is introduced into the melt, the reaction gas is transmitted by the composite transmission tube 100, and the reaction gas is a high-pressure reaction gas with a certain pressure, such as oxygen. Two composite transmission tubes 100 are detachably connected to the opposite sides of the anode furnace body 300, so that the high-pressure reaction gas can be output from two positions on the side of the anode furnace body 300, so that the melt in the anode furnace body 300 can be output in two directions and react with the corresponding melt, thereby shortening the reaction time between the melt and the reaction gas, and the high-pressure reaction gas of the same pressure is output through the corresponding output ends of the two composite transmission tubes 100, and reacts with each other in the anode furnace body 300. Impact to form a composite reaction gas, that is, part of the solution close to the composite transmission tube 100, that is, part of the solution located on the side of the anode furnace body 300 can completely react with the high-pressure reaction gas, and as the high-pressure reaction gas reacts with the side solution, the concentration of the reaction gas will decrease. The high-pressure characteristic of the reaction gas in this embodiment is utilized to enable the reaction gas to be transmitted to the middle of the anode furnace body 300, and a composite reaction gas is formed through the mutual impact of the two high-pressure gases. The composite reaction gas is used to react with the solution in the middle, thereby solving the technical problems in the prior art that a certain amount of copper is oxidized and part of FeS cannot react completely with oxygen.

[0054] It should be noted that, since iron oxide, i.e., iron slag, is produced during the reaction of the reaction gas with the solution, and the iron slag floats on the surface of the solution, in the prior art, the anode furnace body 300 is usually flipped sideways to allow the iron slag to be discharged from the anode furnace body 300 along with the solution. However, the operation mode of the prior art may result in the problem that the iron slag cannot be completely cleaned from the surface of the solution. In this example, a collecting sleeve 200 arranged on each composite transmission pipe 100 is lifted and lowered, so that the collecting sleeve 200 is driven to move up and down, so that the collecting sleeve 200 is located below the liquid surface of the solution. The movement trajectory of the fluid is used to collect the floating medium floating on the surface of the solution along with the flow of the solution in the collecting sleeve 200, thereby solving the problem that the operation of cleaning the iron slag is difficult and the problem that the iron slag cannot be completely cleaned from the surface of the solution is solved.

[0055] After the iron slag enters the collecting sleeve 200, a part of the melt will enter the collecting sleeve 200 along with the iron slag. In order to avoid waste of the melt, in some preferred embodiments, the collecting sleeve 200 includes a first sub-sleeve 210 and a second sub-sleeve 220 both having through holes. Any one of the first sub-sleeve 210 and the second sub-sleeve 220 is sleeved on the composite transmission pipe 100 and screwed with the composite transmission pipe 100, wherein each through hole on the first sub-sleeve 210 and each through hole in the second sub-sleeve 220 are staggered so that when the first sub-sleeve 210 and the second sub-sleeve 220 are raised and lowered relative to the composite transmission pipe 100, each through hole on the first sub-sleeve 210 and each through hole in the second sub-sleeve 220 are in a concentric state or a staggered state.

[0056] Specifically, the first sub-casing 210 is provided with a plurality of first through holes 211 , and the plurality of first through holes 211 are spaced apart along the circumference and length directions of the first sub-casing 210 , and the second sub-casing 220 is provided with a plurality of second through holes 221 , and the plurality of second through holes 221 are spaced apart along the circumference and length directions of the second sub-casing 220 .

[0057] See also Figure 4-Figure 9 As shown, in this embodiment, the second sub-casing 220 is sleeved outside the first sub-casing 210, and the first sub-casing 210 is sleeved outside the composite transmission tube 100;

[0058] A threaded portion 230 that cooperates with each other is provided between the first sub-casing 210 and the composite transmission tube 100, and a sliding portion 240 that cooperates with each other is provided between the second sub-casing 220 and the composite transmission tube 100, and the sliding direction of the sliding portion 240 is the same as the lifting direction of the first sub-casing 210 and the second sub-casing 220;

[0059] When the first sub-casing 210 and the second sub-casing 220 are lifted and lowered relative to the composite transmission tube 100, the first sub-casing 210 is rotated relative to the second sub-casing 220 and the composite transmission tube 100 to adjust the concentric state or staggered state of the first through hole 211 and the second through hole 221;

[0060] The first sub-tube 210 has a collecting cavity 212 which is interconnected with the first through hole 211 .

[0061] When collecting iron slag, it is necessary to drive the first sub-casing 210 and the second sub-casing 220 to perform synchronous lifting and lowering movements. When collecting iron slag, the first sub-casing 210 and the second sub-casing 220 are in a descending state. The first sub-casing 210 and the composite transmission pipe 100 have mutually matched threaded portions 230, so that the first sub-casing 210 will generate positive rotation during the descending process, and at the same time, the second sub-casing 220 will maintain a lifting and lowering state due to the setting of the sliding portion 240. By utilizing the rotation of the first sub-casing 210, the first through hole 211 on the first sub-casing 210 and the second through hole 220 on the second sub-casing 220 are rotated. 1 is staggered, then each first through hole 211 on the corresponding first sub-casing 210 is blocked by a part of the side wall on the second sub-casing 220, and at the same time, each second through hole 221 on the second sub-casing 220 is blocked by a part of the side wall on the first sub-casing 210, so that the first sub-casing 210 and the second sub-casing 220 are barrel-shaped structures with an opening at the upper end and a closed side wall. Finally, the first sub-casing 210 and the second sub-casing 220 are lowered below the liquid surface of the melt, so that the melt flows into the collection cavity 212, and the iron slag will flow into the collection cavity 212 synchronously during the melt inflow process, thereby completing the collection of the iron slag.

[0062] To avoid wasting the melt, after the iron slag is collected, the first sub-casing 210 and the second sub-casing 220 are driven to rise. Correspondingly, the first sub-casing 210 and the composite transmission tube 100 are again used to cooperate with each other. The threaded portion 230 makes the first sub-casing 210 produce a reverse rotation during the descent process, so that each first through hole 211 on the first sub-casing 210 and each second through hole 221 on the second sub-casing 220 are concentric. At this time, the collecting chamber 212 will be connected to the outside, and the melt stored in the collecting chamber 212 will pass through the first through hole 211 and the second through hole 221 in turn and fall into the anode furnace body 300, and the iron slag is filtered through the first through hole 211 and the second through hole 221 in the collecting chamber 212 to complete the collection, thereby achieving the effect of collecting the iron slag and separating the melt and the iron slag at the same time.

[0063] Please note that Fig. 9 As shown, the threaded portion 230 shown in this example is only a circle of external threads arranged on the inner side of the first sub-casing 210, and a circle of internal threads arranged on the outer side of the composite transmission pipe 100. By arranging the external threads and the internal threads into a circle, a plurality of first through holes 211 and a plurality of second through holes 221 can be arranged on the first sub-casing 210 and the second sub-casing 220, so as to achieve the purpose of quickly separating the iron slag and the melt.

[0064] Please refer again Figure 8As shown, the sliding portion 240 may be a slide rail disposed on the outside of the composite transmission tube 100 , and a slider disposed on the inside of the first sub-casing 210 , and the slider is slidably connected to the slide rail.

[0065] Furthermore, in order to facilitate driving the first sub-casing 210 and the second sub-casing 220 to rise and fall, the collecting casing 200 also includes a plurality of connecting rods 250 and a lifting connector 260. The lifting connector 260 is connected to the end of the first sub-casing 210 through the plurality of connecting rods 250, and the plurality of connecting rods 250 are arranged at intervals along the end of the casing to form a lifting section 270 for the composite transmission pipe 100 to pass through between the plurality of connecting rods 250, wherein the lifting connector 260 is used to connect to the lifting drive member.

[0066] It should be noted that the lifting drive member can adopt the cylinder in the prior art. Specifically, a support frame can be arranged on the outer side of the anode furnace body 300, and the lifting drive member can be installed on the support frame, and a connecting member can be installed at the output end of the cylinder. The upper roller and the lower roller are installed on the connecting member, and the lifting connection member 260 is placed between the upper roller and the lower roller. When the lifting drive member drives the upper roller and the lower roller to lift, the upper roller and the lower roller will roll on the top and bottom surfaces of the lifting connection member 260 respectively, thereby realizing the lifting movement of the first sub-tube body 112 and the second sub-tube body 122.

[0067] Furthermore, in order to prevent iron slag from remaining at the bottom of the second sub-casing 220, in some preferred embodiments, the bottom size of the second sub-casing 220 extends outward from large to small. For details, please refer to Figure 7 As shown, by limiting the size of the bottom of the second sub-casing 220, the iron slag moves along the surface of the bottom of the second sub-casing 220 during the descending process of the second sub-casing 220, so that all the iron slag can float on the surface of the melt and be collected.

[0068] In addition, to facilitate understanding of the transmission of high-pressure reaction gas in this embodiment, in this embodiment, the anode furnace may include two composite transmission tubes 100, such as a first composite transmission tube 110 and a second composite transmission tube 120, and it should be noted that the first composite transmission tube 110 and the second composite transmission tube 120 are not limited to the number of composite transmission tubes 100, and may also include four composite transmission tubes 100, etc., without special limitation herein. When four composite transmission tubes 100 are used, the four composite transmission tubes 100 may be respectively located at the upper, lower, left and right positions of the anode furnace body 300.

[0069] Furthermore, the first composite transmission tube 110 includes a first main body 111 and at least two first sub-tubes 112 sleeved in the first main body 111, each first sub-tube 112 is connected to the first main body 111, and one of the first sub-tubes 112 and the first main body 111 has a plurality of connecting portions to form a plurality of first sub-output ends 113, and another first sub-tube 112 and the first main body 111 has at least one connecting portion to form at least one first sub-high-voltage output end 114, wherein the first sub-high-voltage output end 114 is located below the first sub-output end 113.

[0070] The second composite transmission tube 120 includes a second main body 121 and at least two second sub-tubes 122 sleeved in the second main body 121, wherein each second sub-tube 122 is connected to the second main body 121, and one of the second sub-tubes 122 and the second main body 121 has a plurality of connecting portions to form a plurality of second sub-output ends 123, and another second sub-tube 122 and the second main body 121 has at least one connecting portion to form at least one second sub-high-voltage output end 124, wherein the second sub-high-voltage output end 124 is located below the second sub-output end 123.

[0071] In order to allow the iron slag to float quickly on the surface of the melt, in this embodiment, the gas pressure output by the first sub-output terminal 113 is less than the gas pressure output by the first sub-high-pressure output terminal 114, the gas pressure output by the second sub-output terminal 123 is less than the gas pressure output by the second sub-high-pressure output terminal 124, the gas pressure output by the first sub-output terminal 113 is equal to the gas pressure output by the second sub-output terminal 123, and the gas pressure output by the first sub-high-pressure output terminal 114 is equal to the gas pressure output by the second sub-high-pressure output terminal 124, wherein the bottom of the anode furnace has a gas guide portion whose size increases successively and is arranged corresponding to the first sub-high-pressure output terminal 114 and the second sub-high-pressure output terminal 124, and by limiting the pressure of the first sub-high-pressure output terminal 114 and the pressure of the second sub-high-pressure output terminal 124, the high-pressure reaction gas output by the first sub-high-pressure output terminal 114 and the high-pressure reaction gas output by the second sub-high-pressure output terminal 124 can be transmitted along the guide direction of the gas guide portion respectively.

[0072] Specifically, the high-pressure reaction gas output from the first sub-high-pressure output terminal 114 and the high-pressure reaction gas output from the second sub-high-pressure output terminal 124 can be combined into a high-pressure reaction gas with the highest pressure, and the high-pressure reaction gas is directed toward the top of the melt, so that all the iron slag in the melt can float on the surface of the melt due to the transmission direction of the high-pressure reaction gas.

[0073] In summary, the anode furnace for copper smelting provided by the first embodiment of the present invention has at least the following beneficial effects compared to the conventional method of introducing oxygen into the anode furnace:

[0074] 1. In an anode furnace for copper smelting provided by the present invention, a plurality of composite transmission tubes 100 and a plurality of collecting sleeves 200 are arranged on the anode furnace body 300, and each two collecting sleeves 200 in the plurality of composite transmission tubes 100 are used to be detachably connected to the opposite sides of the anode furnace body 300, and each collecting sleeve 200 is respectively lifted and lowered on each composite transmission tube 100, so that when the reaction gas is introduced into the melt, the composite transmission tube 100 is used to transmit the reaction gas, and the reaction gas is a high-pressure reaction gas with a certain pressure. Each two composite transmission tubes 100 are detachably connected to the opposite sides of the anode furnace body 300, so that the high-pressure reaction gas can be output from two sides of the anode furnace body 300, so that the melt in the anode furnace body 300 can be output in two directions and react with the corresponding melt, thereby The reaction time of the solution and the reaction gas is shortened, and high-pressure reaction gases of the same pressure are output through the corresponding output ends of the two composite transmission tubes 100, and impact each other in the anode furnace body 300 to form a composite reaction gas, that is, part of the solution close to the composite transmission tube 100, that is, part of the solution located on the side of the anode furnace body 300 can react completely with the high-pressure reaction gas, and as the high-pressure reaction gas reacts with the side solution, the concentration of the reaction gas decreases. The high-pressure characteristic of the reaction gas in this embodiment is utilized to enable the reaction gas to be transmitted to the middle of the anode furnace body 300, and the composite reaction gas is formed by the mutual impact of the two high-pressure gases. The composite reaction gas is used to react with the solution in the middle, thereby solving the technical problems in the prior art that a certain amount of copper is oxidized and part of FeS cannot react completely with oxygen.

[0075] 2. Since iron oxide, i.e., iron slag, is generated during the reaction of the reaction gas with the solution, and the iron slag floats on the surface of the solution, in the prior art, the anode furnace body 300 is usually turned sideways to allow the iron slag to be discharged from the anode furnace body 300 along with the solution. However, the operation method of the prior art may result in the problem that the iron slag cannot be completely cleaned from the surface of the solution. In this example, a collecting sleeve 200 arranged on each composite transmission pipe 100 is lifted and lowered to drive the collecting sleeve 200 to move up and down, so that the collecting sleeve 200 is located below the liquid surface of the solution. The movement trajectory of the fluid is used to collect the floating medium floating on the surface of the solution along with the flow of the solution in the collecting sleeve 200, thereby solving the problem that the operation of cleaning the iron slag is difficult and the problem that the iron slag cannot be completely cleaned from the surface of the solution is solved.
