[0046] When the user needs to refine the recycled copper by using the device for refining oxygen-free copper from recycled copper of the present application, first, the user adds the recycled copper into the preheating assembly 1000, the preheating assembly 1000 preheats the recycled copper, then the preheated recycled copper is added into the stirring assembly 3000 in the melting furnace 2000, then the melting furnace 2000 generates high temperature to melt the recycled copper in the stirring assembly 3000, at the same time, the stirring assembly 3000 can ensure the recycled copper to keep moving during the melting process, thereby improving the melting efficiency of the recycled copper.

[0047] When the recycled copper is melted, the ventilation assembly 4000 fills the melting furnace 2000 with carbon monoxide, and then the carbon monoxide and the melted recycled copper undergo the following chemical reaction:

[0048] CuO + CO = Cu + CO2;

[0049] Then, a small amount of deoxidizer is added to the stirring assembly 3000 through the deoxidizing assembly 5000, so that the copper reacts with the deoxidizer to produce oxygen-free copper, and the deoxidizer can be copper boron alloy or rare earth, etc.

[0050] Finally, the prepared oxygen-free copper is added to the forming assembly 6000, and the forming assembly 6000 presses the oxygen-free copper into a fixed shape, thereby completing the preparation process of the whole oxygen-free copper.

[0051] It is worth noting that the melting furnace 2000 is a melting furnace 2000 in the prior art, which can generate high temperature reaching the melting point of copper.

[0052] Moreover, the transportation of copper in each assembly can be transported by manual transportation or conventional handling equipment in the prior art, such as a mechanical hand, etc.

[0053] In the embodiment, the preheating assembly 1000 includes a preheating box 1100, a preheating conveying member, a plurality of first preheating members 1300 and a plurality of second preheating members 1400, the preheating conveying member is installed in the preheating box 1100, the first preheating members 1300 are installed on the lower side of the preheating conveying member, and the second preheating members 1400 are installed on the upper side of the preheating conveying member.

[0054] The preheating box 1100 plays a role of fixing and supporting each structure in the preheating assembly 1000, and the preheating conveying member drives the recycled copper to move in the preheating box 1100, so that the recycled copper passes through the first preheating members 1300 and the second preheating members 1400, and the first preheating members 1300 and the second preheating members 1400 generate temperature to preheat the recycled copper.

[0055] In the embodiment, the preheating conveying member comprises a preheating conveying support 1210, a preheating conveying driving gear 1220, a preheating conveying motor 1230, a preheating conveying belt 1240, a preheating conveying driven gear 1250 and a preheating conveying chain, the preheating conveying support 1210 is installed in the preheating box 1100, the preheating conveying driving gear 1220 is rotatably connected to one end of the preheating conveying support 1210, the preheating conveying driven gear 1250 is rotatably connected to the other end of the preheating conveying support 1210, the preheating conveying chain is rotatably connected between the preheating conveying driving gear 1220 and the preheating conveying driven gear 1250, the preheating conveying motor 1230 is installed in the preheating box 1100, and the preheating conveying belt 1240 is installed between the output end of the preheating conveying motor 1230 and the preheating conveying driving gear 1220.

[0056] Preheating conveying support 1210 plays a fixed supporting role in each structure in the preheating conveying member. When the regenerated copper needs to be transported in the preheating box 1100, first, the preheating conveying motor 1230 enters the working state, the output end of the preheating conveying motor 1230 drives the preheating conveying belt 1240 to rotate, so that the preheating conveying belt 1240 drives the preheating conveying driving gear 1220 to rotate, so that the preheating driving gear drives the preheating conveying chain to rotate between the preheating driving gear and the preheating driven gear, and then the preheating conveying chain plays a rotating role for the regenerated copper.

[0057] Specifically, each structure in the preheating conveying member can be provided with two, and the regenerated copper has a certain length, so when the regenerated copper needs to be transported, the user places the regenerated copper on the preheating conveying chain.

[0058] In the embodiment, the first preheating member 1300 comprises a first preheating limiting block 1310, a second preheating limiting block 1320, a preheating pipe 1330 and a heat radiation member, the first preheating limiting block 1310 and the second preheating limiting block 1320 are both installed in the preheating box body 1100, the preheating pipe 1330 is installed between the first preheating limiting block 1310 and the second preheating limiting block 1320, and the heat radiation member is installed on one side of the preheating pipe 1330; the heat radiation member comprises a heat radiation bottom plate 1341, a first heat radiation side plate 1342 and a second heat radiation side plate 1343, the heat radiation bottom plate 1341 is installed between the preheating pipe 1330 and the preheating box body 1100, the first heat radiation side plate 1342 is installed on one side of the heat radiation bottom plate 1341, the second heat radiation side plate 1343 is installed on the other side of the heat radiation bottom plate 1341, a plurality of heat diffusion plates 1344 are installed on the first heat radiation side plate 1342 and the second heat radiation side plate 1343, and heat diffusion channels 1345 are formed between the heat diffusion plates 1344; the second preheating member 1400 and the first preheating member 1300 are the same in structure;

[0059] The first preheating limiting block 1310 and the second preheating limiting block 1320 jointly clamp and limit the preheating pipe 1330, so as to ensure the stability of the preheating pipe 1330, and then the preheating pipe 1330 generates temperature to preheat the regenerated copper conveyed on the preheating conveying member;

[0060] Meanwhile, the heat generated by the preheating pipe 1330 can flow more concentratedly to the regenerated copper on the preheating conveying member through the heat radiation member;

[0061] Specifically, the heat radiation bottom plate 1341 plays a role of fixing and supporting the heat radiation member, the first heat radiation side plate 1342 and the second heat radiation side plate 1343 are both arranged in an inclined manner, meanwhile, the heat generated by the preheating pipe 1330 is collected into the heat diffusion channels 1345, and then the heat generated by the preheating pipe 1330 is transmitted to the preheating conveying member better and more concentratedly through the heat diffusion channels 1345;

[0062] The second preheating member 1400 and the first preheating member 1300 are the same in structure, therefore, the working principle of the second preheating member 1400 is completely the same as that of the first preheating member 1300.

[0063] In the embodiment, the stirring assembly 3000 comprises a stirring heat-insulating box 3100, a stirring motor 3200, a stirring linkage rod 3300, a first stirring blade 3400, a second stirring blade 3500, a stirring accommodating portion 3600 and a stirring clamping seat 3700. The stirring heat-insulating box 3100 is installed on the upper side of the melting furnace 2000. The stirring motor 3200 is installed in the stirring heat-insulating box 3100. One end of the stirring linkage rod 3300 is connected with the output end of the stirring motor 3200. The other end of the stirring linkage rod 3300 extends into the melting furnace 2000. The stirring clamping seat 3700 is installed in the melting furnace 2000. The stirring accommodating portion 3600 is installed on the stirring clamping seat 3700. The first stirring blade 3400 and the second stirring blade 3500 are connected with the lower end of the stirring linkage rod 3300. The lower ends of the first stirring blade 3400 and the second stirring blade 3500 abut against the inner wall of the stirring accommodating portion 3600.

[0064] The stirring heat-insulating box 3100 protects the stirring motor 3200 to a certain extent. The stirring clamping seat 3700 ensures the stability of the stirring accommodating portion 3600. When the regenerated copper needs to be melted, the regenerated copper is added into the stirring accommodating portion 3600. Then, the melting furnace 2000 starts to work. At the same time, the stirring motor 3200 also enters the working state. Thus, the output end of the stirring motor 3200 drives the stirring linkage rod 3300 to rotate. Then, the stirring linkage rod 3300 drives the first stirring blade 3400 and the second stirring blade 3500 to rotate. Thus, the first stirring blade 3400 and the second stirring blade 3500 drive the regenerated copper to rotate in the stirring accommodating portion 3600. Thus, the melting efficiency of the regenerated copper is improved.

[0065] Further, the lower sides of the first stirring blade 3400 and the second stirring blade 3500 are in the shape of a circular arc. Thus, the lower sides of the first stirring blade 3400 and the second stirring blade 3500 are attached to the inner bottom surface of the stirring accommodating portion 3600. Thus, the stirring effect of the first stirring blade 3400 and the second stirring blade 3500 on the regenerated copper is ensured.

[0066] In the embodiment, the aeration assembly 4000 comprises an aeration base 4100, an aeration fan 4200, an aeration part 4300, an aeration main channel 4400, an aeration covering channel 4500, a plurality of aeration channels 4600 and an aeration buffer 4700. The aeration base 4100 is installed on one side of the melting furnace 2000. The aeration fan 4200 is installed on the aeration base 4100. The aeration part 4300 is installed on one side of the aeration fan 4200. The aeration covering channel 4500 is installed outside the melting furnace 2000. One end of the aeration main channel 4400 is connected with the output end of the aeration fan 4200. The other end of the aeration main channel 4400 is connected with the aeration covering channel 4500. The plurality of aeration channels 4600 are installed on the lower side of the aeration covering channel 4500. The aeration buffer 4700 is installed on the lower end of the aeration channel 4600.

[0067] The aeration base 4100 supports the various mechanisms in the aeration assembly 4000. When the recycled copper is melted in the stirring container 3600, the external gas supply device is connected with the aeration part 4300, so that the external carbon monoxide enters the aeration fan 4200. Then, the aeration fan 4200 enters the working state. The aeration fan 4200 blows the carbon monoxide into the aeration main channel 4400, and then into the aeration covering channel 4500. Then, the carbon monoxide enters the plurality of aeration channels 4600 and the aeration buffer 4700. The carbon monoxide passing through the aeration buffer 4700 enters the melting furnace 2000 from various angles, so as to ensure that the carbon monoxide uniformly enters the melting furnace 2000.

[0068] In the embodiment, the air intake buffer 4700 comprises an air intake buffer main body 4710, a buffer air intake passage 4720, a first arc-shaped buffer passage 4730, a second arc-shaped buffer passage 4740, a buffer air outlet passage 4750, and a flow control member; the air intake buffer main body 4710 is installed on one side of the melting furnace 2000, the buffer air intake passage 4720 is installed in the air intake buffer main body 4710, the first arc-shaped buffer passage 4730 is installed on the lower side of the buffer air intake passage 4720, the second arc-shaped buffer passage 4740 is installed on the lower side of the first arc-shaped buffer passage 4730, one end of the buffer air outlet passage 4750 is connected with the lower end of the second arc-shaped buffer passage 4740, the other end of the buffer air outlet passage 4750 extends into the melting furnace 2000, and the flow control member is installed outside the buffer main body 4710; the flow control member comprises a flow cylinder 4810 and a flow push plate 4820, the flow cylinder 4810 is installed outside the air intake buffer main body 4710, the flow push plate 4820 is slidingly connected in the air intake buffer main body 4710, one end of the flow push plate 4820 is connected with the output end of the flow cylinder 4810, and the other end of the flow push plate 4820 extends into the second arc-shaped buffer passage 4740.

[0069] The air intake buffer main body 4710 plays a role of fixing and supporting each structure in the air intake buffer 4700, carbon monoxide passing through the air intake passage 4600 enters the buffer air intake passage 4720, then enters the first arc-shaped buffer passage 4730 and the second arc-shaped buffer passage 4740, and finally enters the melting furnace 2000 through the buffer air outlet passage 4750.

[0070] It is worth noting that the first arc-shaped buffer passage 4730 and the second arc-shaped buffer passage 4740 play a role of buffering carbon monoxide, thereby ensuring the stability of carbon monoxide entering the melting furnace 2000, and thus improving the reaction effect of carbon monoxide entering the melting furnace 2000 with the regenerated copper to some extent.

[0071] Meanwhile, the first arc-shaped buffer passage 4730 and the second arc-shaped buffer passage 4740 are both in a circular arc structure, and the first arc-shaped buffer passage 4730 and the second arc-shaped buffer passage 4740 are different in direction, thereby further ensuring the blocking and buffering effect of carbon monoxide.

[0072] The flow control member can adjust the amount of carbon monoxide in real time, so that the user can adjust the amount of carbon monoxide entering the melting furnace 2000 in real time through the flow control member.
