Item A can include a single element or multiple elements. Item B can include a single element or multiple elements. Item C can include a single element or multiple elements.
[0049] Referring to Figures 1-10 As shown in the drawings, the present application provides an anode furnace applied to oxidative copper smelting, which comprises a plurality of composite transmission pipes 100, a plurality of collecting sleeves 200, and an anode furnace body 300 for containing a copper melt. In the embodiment, the anode furnace body 300 belongs to a device for smelting blister copper, which is mainly used for smelting blister copper into a melt. It should be noted that the components of the anode furnace body 300 belong to the conventional prior art in the field, and thus are not described in detail herein.
[0050] Specifically, in the embodiment, every two collecting sleeves 200 in the plurality of composite transmission pipes 100 are used for detachably connecting to opposite sides of the anode furnace body 300, and the output end of each composite transmission pipe 100 is used for extending into the melt and transmitting high-pressure reaction gas towards the melt.
[0051] The high-pressure reaction gas with the same pressure is output through the corresponding output end of each of the two composite transmission pipes 100 and impacts each other in the anode furnace body 300 to form a composite reaction gas. 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] Wherein each collecting sleeve 200 is respectively arranged on each composite transmission pipe 100, and by driving the lifting of each collecting sleeve 200 relative to each composite transmission pipe 100, the collecting end of the collecting sleeve 200 is located below the liquid level of the melt, so as to collect the floating medium in the collecting sleeve 200.
[0053] For the convenience of understanding the present case, please refer to Figures 2-4 As shown in the figure, when the reaction gas is introduced into the melt, the composite transmission pipe 100 is used to transmit the reaction gas, and the reaction gas is a high-pressure reaction gas with a certain pressure, such as oxygen. By detachably connecting each two composite transmission pipes 100 on the opposite sides of the anode furnace body 300, the high-pressure reaction gas can be output from the two parts 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 of the melt and the reaction gas. And output the same pressure high-pressure reaction gas through the corresponding output end of the two composite transmission pipes 100 respectively and impact each other in the anode furnace body 300 to form a composite reaction gas, that is, the part of the melt close to the composite transmission pipe 100, that is, the part of the melt on the side of the anode furnace body 300 can be completely reacted with the high-pressure reaction gas. With the reaction of the high-pressure reaction gas and the side melt, the concentration of the reaction gas will decrease, and the reaction gas with high pressure in the present embodiment can be transmitted to the middle part of the anode furnace body 300, and the composite reaction gas is formed by the mutual impact of the two high-pressure gases, and the melt in the middle part is reacted by the composite reaction gas, thereby solving the technical problems of existing technology that some copper is oxidized and part of FeS cannot be completely reacted with oxygen.
[0054] It should be noted that during the reaction of the reaction gas and the melt, iron oxide, i.e. iron slag, will be produced, and the iron slag will float on the surface of the melt. In the prior art, the anode furnace body 300 is usually turned on its side to let the iron slag flow out of the anode furnace body 300 with the melt, but the operation mode of the prior art will cause the problem that the iron slag cannot be completely cleaned from the surface of the melt. In the present example, the collecting sleeve 200 arranged on each composite transmission pipe 100 is driven to move up and down, so that the collecting sleeve 200 is located below the liquid level of the melt, and the floating medium floating on the surface of the melt is collected in the collecting sleeve 200 with the flow of the melt, thereby solving the problems of difficult operation of cleaning the iron slag and inability to completely clean the iron slag from the surface of the melt.
[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. To avoid waste of the melt, in some preferred embodiments, the collecting sleeve 200 comprises a first sub-sleeve 210 and a second sub-sleeve 220, each having through holes. Either the first sub-sleeve 210 or the second sub-sleeve 220 is sleeved on the composite conveying pipe 100 and is screwed with the composite conveying pipe 100. Each through hole on the first sub-sleeve 210 and each through hole on the second sub-sleeve 220 are staggered, so that each through hole on the first sub-sleeve 210 and each through hole on the second sub-sleeve 220 are concentric or staggered when the first sub-sleeve 210 and the second sub-sleeve 220 are raised or lowered relative to the composite conveying pipe 100.
[0056] Specifically, the first sub-sleeve 210 is provided with a plurality of first through holes 211, and the plurality of first through holes 211 are arranged along the circumferential direction and the length direction of the first sub-sleeve 210. The second sub-sleeve 220 is provided with a plurality of second through holes 221, and the plurality of second through holes 221 are arranged along the circumferential direction and the length direction of the second sub-sleeve 220.
[0057] Please refer to Figures 4-9 In this embodiment, the second sub-sleeve 220 is sleeved outside the first sub-sleeve 210, and the first sub-sleeve 210 is sleeved outside the composite conveying pipe 100.
[0058] The first sub-sleeve 210 and the composite conveying pipe 100 have a thread part 230 that cooperates with each other. The second sub-sleeve 220 and the composite conveying pipe 100 have a sliding part 240 that cooperates with each other. The sliding direction of the sliding part 240 is the same as the raising and lowering direction of the first sub-sleeve 210 and the second sub-sleeve 220.
[0059] When the first sub-sleeve 210 and the second sub-sleeve 220 are raised or lowered relative to the composite conveying pipe 100, the first sub-sleeve 210 rotates relative to the second sub-sleeve 220 and the composite conveying pipe 100 to adjust the concentric or staggered state of the first through holes 211 and the second through holes 221.
[0060] The first sub-sleeve 210 has a collecting cavity 212 that communicates with the first through holes 211.
[0061] When collecting slag, the first sub-sleeve 210 and the second sub-sleeve 220 need to be driven to move up and down synchronously. During slag collection, the first sub-sleeve 210 and the second sub-sleeve 220 are in a descending state. Utilizing the threaded portion 230 that mates with the composite transmission pipe 100, the first sub-sleeve 210 rotates forward during its descent. Simultaneously, the second sub-sleeve 220, due to the sliding portion 240, remains in the ascending / descending state. The rotation of the first sub-sleeve 210 causes the first through hole 211 on the first sub-sleeve 210 and the second through hole 22 on the second sub-sleeve 220 to rotate. If the first sub-sleeve 210 is staggered, each first through hole 211 on the first sub-sleeve 210 is blocked by a portion of the side wall of the second sub-sleeve 220, and at the same time, each second through hole 221 on the second sub-sleeve 220 is blocked by a portion of the side wall of the first sub-sleeve 210. This makes the first sub-sleeve 210 and the second sub-sleeve 220 a barrel-shaped structure with an open top and closed side walls. Finally, the first sub-sleeve 210 and the second sub-sleeve 220 are lowered below the surface of the melt, so that the melt flows into the collection chamber 212. During the flow of the melt, the slag will flow into the collection chamber 212 simultaneously, thereby completing the collection of the slag.
[0062] To avoid wasting the molten material, after the slag is collected, the first sub-sleeve 210 and the second sub-sleeve 220 are driven to rise. Correspondingly, the threaded portion 230 between the first sub-sleeve 210 and the composite transmission pipe 100 causes the first sub-sleeve 210 to rotate in reverse during its descent. This makes each first through hole 211 on the first sub-sleeve 210 and each second through hole 221 on the second sub-sleeve 220 concentric. At this time, the collecting cavity 212 will be connected to the outside. The molten material stored in the collecting cavity 212 will fall into the anode furnace body 300 through the first through hole 211 and the second through hole 221 in sequence. Meanwhile, the slag is filtered into the collecting cavity 212 through the first through hole 211 and the second through hole 221 and collected. This achieves the effect of collecting the slag and separating the molten material from the slag.
[0063] It should be noted that you should refer to [link / reference]. Figure 9 As shown in the example, the threaded part 230 is only a single external thread inside the first sub-sleeve 210 and a single internal thread outside the composite transmission pipe 100. By making the external thread and the internal thread into one loop, multiple first through holes 211 and multiple second through holes 221 can be arranged on the first sub-sleeve 210 and the second sub-sleeve 220, which can achieve the purpose of quickly separating the slag and the melt.
[0064] Please refer to it again. Figure 8As shown, the sliding part 240 can be a sliding rail arranged outside the composite transmission pipe 100, and a sliding block arranged inside the first sub-sleeve 210, and the sliding block is slidingly connected in the sliding rail.
[0065] Further, in order to facilitate driving the first sub-sleeve 210 and the second sub-sleeve 220 to lift, the collecting sleeve 200 further comprises a plurality of connecting rods 250 and a lifting connecting piece 260, the lifting connecting piece 260 is connected with the end of the first sub-sleeve 210 through the plurality of connecting rods 250, and the plurality of connecting rods 250 are arranged along the end of the first sub-sleeve 210 to form a lifting area 270 for the composite transmission pipe 100 to pass through between the plurality of connecting rods 250, wherein the lifting connecting piece 260 is used to be connected with a lifting driving piece.
[0066] It should be noted that the lifting driving piece can adopt a cylinder in the prior art, specifically, a support frame can be arranged outside the anode furnace body 300, the lifting driving piece is installed on the support frame, and an output end of the cylinder can be provided with a connecting piece, an upper roller and a lower roller are installed on the connecting piece, and the lifting connecting piece 260 is placed between the upper roller and the lower roller, so that when the lifting driving piece drives the upper roller and the lower roller to lift, the upper roller and the lower roller will roll on the top surface and the bottom surface of the lifting connecting piece 260 respectively, thereby realizing the lifting movement of the first sub-pipe body 112 and the second sub-pipe body 122.
[0067] Further, in order to avoid that there is iron slag remaining at the bottom of the second sub-sleeve 220, in some preferred embodiments, the size of the bottom of the second sub-sleeve 220 extends outward from large to small, and specific reference can be made to Figure 7 As shown, by limiting the size of the bottom of the second sub-sleeve 220, the iron slag moves along the surface of the bottom of the second sub-sleeve 220 during the descending process, so that all the iron slag can float on the surface of the melt to complete the collection.
[0068] In addition, in order to facilitate the understanding of the transmission of high-pressure reaction gas in this embodiment, the anode furnace can comprise two composite transmission pipes 100, such as the first composite transmission pipe 110 and the second composite transmission pipe 120, and it should be noted that the first composite transmission pipe 110 and the second composite transmission pipe 120 are not limited to the number of composite transmission pipes 100, and it can also comprise four composite transmission pipes 100 and the like, which are not particularly limited here, when four composite transmission pipes 100 are used, the four composite transmission pipes 100 can be arranged at the upper, lower, left and right four parts of the anode furnace body 300.
[0069] Further, the first composite transmission pipe 110 comprises a first main pipe body 111 and at least two first sub-pipe bodies 112 sleeved in the first main pipe body 111, each first sub-pipe body 112 is communicated with the first main pipe body 111, and one of the first sub-pipe bodies 112 and the first main pipe body 111 have multiple communication parts to form multiple first sub-output ends 113, and the other first sub-pipe body 112 and the first main pipe body 111 have at least one communication part to form at least one first sub-high pressure output end 114, wherein the first sub-high pressure output end 114 is located below the first sub-output end 113.
[0070] The second composite transmission pipe 120 comprises a second main pipe body 121 and at least two second sub-pipe bodies 122 sleeved in the second main pipe body 121, each second sub-pipe body 122 is communicated with the second main pipe body 121, and one of the second sub-pipe bodies 122 and the second main pipe body 121 have multiple communication parts to form multiple second sub-output ends 123, and the other second sub-pipe body 122 and the second main pipe body 121 have at least one communication part to form at least one second sub-high pressure output end 124, wherein the second sub-high pressure output end 124 is located below the second sub-output end 123.
[0071] In order to enable the iron slag to float quickly on the surface of the melt, in the embodiment, the gas pressure output by the first sub-output end 113 is less than the gas pressure output by the first sub-high pressure output end 114, the gas pressure output by the second sub-output end 123 is less than the gas pressure output by the second sub-high pressure output end 124, the gas pressure output by the first sub-output end 113 is equal to the gas pressure output by the second sub-output end 123, and the gas pressure output by the first sub-high pressure output end 114 is equal to the gas pressure output by the second sub-high pressure output end 124, wherein the bottom of the anode furnace is provided with gas guiding parts with sizes increasing in sequence and corresponding to the first sub-high pressure output end 114 and the second sub-high pressure output end 124, and by limiting the pressure of the first sub-high pressure output end 114 and the pressure of the second sub-high pressure output end 124, the high pressure reaction gas output by the first sub-high pressure output end 114 and the high pressure reaction gas output by the second sub-high pressure output end 124 can be transmitted along the guiding direction of the gas guiding parts, respectively.
[0072] Specifically, the high pressure reaction gas output by the first sub-high pressure output end 114 and the high pressure reaction gas output by the second sub-high pressure output end 124 can be combined into one high pressure reaction gas with the maximum pressure, and the high pressure reaction gas is directed to the top of the melt, so that all the iron slag in the melt can be floated on the surface of the melt by the transmission direction of the high pressure reaction gas.
[0073] In summary, the anode furnace for copper oxidation smelting provided by the first embodiment of the present application has at least the following beneficial effects compared with the conventional method of introducing oxygen into the anode furnace:

During the reaction of the reaction gas and the melt, iron oxide, i.e. iron slag, is produced, and the iron slag floats on the surface of the melt, and in the prior art, the anode furnace body 300 is usually turned on its side, and the iron slag is discharged out of the anode furnace body 300 with the melt, but the operation mode of the prior art cannot completely clean the iron slag from the surface of the melt, so in the present example, the collecting sleeve 200 arranged on each composite transmission pipe 100 is driven to move up and down, so that the collecting sleeve 200 is below the liquid level of the melt, and the floating medium floating on the surface of the melt is collected in the collecting sleeve 200 with the flow of the melt, thereby solving the problems of difficult operation of cleaning the iron slag and inability to completely clean the iron slag from the surface of the melt.
