Description

Technical Field

[0001] This invention relates to the field of copper alloy refining technology, and in particular to a refining apparatus for processing copper alloy materials. Background Technology

[0002] Currently, refining equipment for copper alloy processing typically requires the addition of combustion-supporting gases, oxidants, and reducing agents during the copper refining process, corresponding to the three steps of smelting, oxidation, and reduction, respectively, to improve the quality of copper refining. However, existing equipment directly introduces the connecting pipes into the refining furnace for these additions. During the refining process, the slag produced easily adheres to and solidifies, clogging the through holes of the connecting pipes. This leads to pipe blockage during subsequent additions, preventing the normal addition of the corresponding gases and affecting the refining of the molten copper.

[0003] Therefore, a refining apparatus for processing copper alloy materials is proposed to solve the above problems. Summary of the Invention

[0006] Preferably, an installation plate is fixedly connected to the inner wall of the installation tube, and a guide rod is fixedly connected to the side of the installation plate away from the installation block. The surface of the guide rod has three through slots arranged in a triangular pattern, and the surface of the installation plate has guide holes corresponding to the through slots.

[0007] Preferably, a sealing ring is slidably connected to the surface of the guide rod, and a uniformly distributed spring is fixedly connected between the sealing ring and the mounting plate. A connecting plate is fixedly connected to the side of the sealing ring near the mounting plate, and the other end of the connecting plate extends through the mounting plate and is fixedly connected to a stop block.

[0008] Preferably, the diameter of the stop block is the same as the inner diameter of the sealing ring, and the stop block is slidably connected to the inner wall of the sealing ring. The side of the stop block near the mounting plate is provided with an inclined surface.

[0009] Preferably, the dust treatment structure includes a treatment tank disposed on one side of the furnace body, a partition is fixedly connected to the inner wall of the treatment tank, a treatment cavity is formed between the inner wall of the treatment tank and the bottom of the partition, an exhaust cavity is formed between the inner wall of the treatment tank and the top of the partition, the surface of the partition is provided with evenly distributed ventilation holes, the bottom of the treatment tank is connected to an exhaust pipe, and the interior of the treatment cavity is filled with sedimentation water.

[0010] Preferably, a connecting box is provided between the processing tank and the furnace body, and both ends of the connecting box are connected to inlet pipes. One end of the inlet pipe is connected to the top of the furnace body, and the other end of the inlet pipe passes through the processing tank and the partition in sequence and extends into the interior of the processing chamber.

[0011] Preferably, the top of the treatment tank is provided with a connecting shell, the bottom of the connecting shell is connected to an exhaust pipe, the exhaust pipe passes through the treatment tank and is connected to the exhaust chamber, and a duct fan is provided inside the connecting shell.

[0012] Preferably, the preheating structure includes a liquid storage tank disposed between the furnace body and the processing tank. The liquid storage tank is filled with a heat exchange medium. A pump body is disposed inside the liquid storage tank. A heat exchange tube is connected to the top of the pump body. One end of the heat exchange tube passes through the liquid storage tank and the connecting box in sequence and is connected to a heat conduction tube.

[0013] Preferably, the other end of the heat pipe spirals around three connecting pipes in sequence, and the other end of the heat pipe is connected to the liquid storage tank, with the liquid level of the heat exchange medium being lower than the connection point between the heat pipe and the liquid storage tank.

[0014] The beneficial effects of this invention are:

[0015] 1. By setting up an adding structure, during the gas adding process, the gas pushes the sealing block and drives the baffle out, thereby clearing the slag adhering to the installation pipe opening. This avoids the situation where slag adheres to the gas inlet and causes blockage, preventing normal gas delivery. When no gas is added, the baffle is reset under the combined action of the spring, sealing ring, and connecting plate, thus blocking the connection between the sealing ring and the furnace body. This prevents some slag and dust from entering the installation pipe and connecting pipe and causing blockage when no gas is added. After the sealing ring resets, it can then perform a secondary seal, improving the anti-blocking effect.

[0016] 2. By setting up an addition structure, the inclined surface of the baffle can guide the gas during the gas addition process, causing it to flow downwards at an angle, thereby increasing the contact area between the gas and the melt. During the slag removal stage, under the action of the annularly distributed injection structure, the introduced airflow blows the slag on the surface of the copper liquid and, under the action of the airflow, causes the copper liquid to surge away from the injection structure, accelerating the movement of the slag towards the feeding port. At the same time, during this process, the surging copper liquid can carry the slag and some copper liquid into the interior of the collection box. The copper liquid can be guided back through the through hole for further refining, while the slag can be retained inside the collection box, making it easier to remove slag uniformly, reducing the difficulty of slag removal, and thus enhancing the usage effect.

[0017] 3. By setting up a dust treatment structure, the dust and slag in the furnace gas can be filtered and settled in the sedimentation water, reducing the pollution of the atmosphere caused by the dust and slag discharged with the furnace gas. At the same time, under the action of negative pressure, the discharge process of furnace gas and dust in the furnace body can be accelerated, reducing the impact of slow discharge of furnace gas and dust on copper refining.

[0018] 4. By setting up a preheating structure, the heat carried by the furnace gas in the inlet connection box can be absorbed, reducing the heat in the flue gas treatment structure. This reduces the amount of water vapor discharged from the sedimentation water due to the high temperature of the furnace gas, thus reducing the loss of sedimentation water and the cost of use. At the same time, the heat is preheated by the heat exchange tube and the heat conduction tube, which avoids the situation where the temperature inside the furnace drops due to the low temperature of the gas during the gas addition process, which is not conducive to copper refining, and improves the resource utilization rate.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In practical implementation: such as Figure 1-8As shown, a refining apparatus for processing copper alloy materials includes: a furnace body 1, with a feeding port 101 on its surface and a furnace door that mates with the feeding port 101 on its surface; a collection box 102 fixedly connected to the inner wall of the furnace body 1, with uniformly distributed through holes 103 on its surface; and three injection structures 2 arranged in a ring on the surface of the furnace body 1, symmetrically distributed with the collection box 102. The injection structures 2 are used for injecting combustion-supporting gas, oxidant, and reducing agent. Add; a dust treatment structure 3, which is located on one side of the furnace body 1 and connected to the furnace body 1, and is used to purify and discharge the flue gas generated during the refining process of the furnace body 1; a preheating structure 4, which is located between the dust treatment structure 3 and the furnace body 1, and is used to reuse the heat of the discharged flue gas. The raw material is introduced into the interior of the furnace body 1 through the feeding port 101. During the refining process, combustion-supporting gas, oxidant and reducing agent can be added through the injection structure 2 to carry out melting, oxidation and reduction steps.

[0030] like Figure 1-5As shown, the injection structure 2 includes an installation block 201 fixedly connected to the inner wall of the furnace body 1. An installation pipe 202 is fixedly connected to the inner wall of the installation block 201. One end of the installation pipe 202 passes through the installation block 201 and the furnace body 1 and is connected to a connecting pipe 203. Three addition pipes 204 are connected to the surface of the connecting pipe 203. A sealing ring 213 is fixedly connected to the inner wall of the installation pipe 202. The three addition pipes 204 are respectively connected to a combustion-supporting gas pipe, an oxidant pipe, and a reducing agent pipe. Valves are provided on the surface of the addition pipes 204, allowing for different additions by controlling the closing of the valves. The added gas is introduced into the interior of the furnace body 1 through the connecting pipe 203 and the installation pipe 202. An installation plate 205 is fixedly connected to the inner wall of the installation pipe 202. A guide rod 206 is fixedly connected to the side away from the mounting block 201. Three through slots 207 are formed on the surface of the guide rod 206, arranged in a triangular pattern. Guide holes 208 corresponding to the through slots 207 are formed on the surface of the mounting plate 205. A sealing ring 209 is slidably connected to the surface of the guide rod 206. Evenly distributed springs 210 are fixedly connected between the sealing ring 209 and the mounting plate 205. A connecting plate 211 is fixedly connected to the side of the sealing ring 209 closest to the mounting plate 205. The other end of the connecting plate 211 extends through the mounting plate 205 and is fixedly connected to a stop block 212. The diameter of the stop block 212 is the same as the inner diameter of the sealing ring 213, and the stop block 212 is slidably connected to the inner wall of the sealing ring 213. 2. An inclined surface is provided on the side near the mounting plate 205. When the introduced gas is introduced into the interior of the mounting pipe 202 through the connecting pipe 203, it can push the sealing ring 209 under the push of the gas. The sealing ring 209 can slide along the surface of the guide rod 206. During this process, the sealing ring 209 can drive the connecting plate 211 to push the stop block 212 out from the interior of the sealing ring 213 until the sealing ring 209 slides past the through groove 207. At this time, the gas can be introduced into the other side of the mounting plate 205 through the through groove 207 and the guide hole 208, and then into the interior of the furnace body 1 through the mounting pipe 202 and the sealing ring 213. During this process, the inclined surface of the stop block 212 can guide the gas, making it flow downward at an inclined angle, thereby increasing the interaction between the gas and the melt. The contact area between the copper and the molten metal is increased to allow for a full reaction with the melt. During the slag removal stage, the airflow from the ring-shaped injection structure 2 blows the slag on the surface of the molten copper away from the injection structure 2, accelerating the movement of the slag towards the feed port 101. The slag is then removed by a slag rake, completing the slag removal process. Simultaneously, the surging molten copper surface carries the slag and some of the molten copper into the collection box 102. The molten copper can be guided back through the through-hole 103 for further refining, while the slag is retained inside the collection box 102 for easier and more consistent slag removal, reducing the difficulty of the process. Adding gas to cause the molten copper surface to surge ensures thorough mixing with the molten copper, further enhancing the performance.When gas addition stops, the sealing ring 209 is reset by the action of spring 210. At this time, the sealing ring 209, through the connecting plate 211, drives the stop block 212 to reset, thus blocking the connection between the sealing ring 213 and the furnace body 1. This prevents some slag and dust from entering the installation pipe 202 and connecting pipe 203 and causing blockage when no gas is added. After the sealing ring 209 resets, it can provide a secondary seal, improving the anti-blocking effect. Simultaneously, some adhered slag can only adhere to the surface of the stop block 212, and can be pushed out and cleared by the stop block 212 when gas is introduced, maintaining good connectivity of the installation pipe 202. During gas introduction, a gas film is formed under the flow of gas to prevent slag and dust from entering the interior of the installation pipe 202.

[0031] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the flue gas treatment structure 3 includes a treatment tank 301 disposed on one side of the furnace body 1. A partition 302 is fixedly connected to the inner wall of the treatment tank 301. A treatment chamber is formed between the inner wall of the treatment tank 301 and the bottom of the partition 302, and an exhaust chamber is formed between the inner wall of the treatment tank 301 and the top of the partition 302. The surface of the partition 302 is provided with evenly distributed ventilation holes. A discharge pipe 304 is connected to the bottom of the treatment tank 301. The interior of the treatment chamber is filled with sedimentation water. A connecting box 305 is provided between the treatment tank 301 and the furnace body 1. Both ends of the connecting box 305 are connected to inlet pipes 303. One end of the inlet pipe 303 is connected to the top of the furnace body 1, and the other end of the inlet pipe 303 passes through the treatment tank 301 and the partition 302 and extends into the interior of the treatment chamber. The furnace gas and flue gas generated during the refining process can be introduced into the interior of the treatment chamber through the inlet pipe 303 and the connecting box 305 and injected into the interior of the sedimentation water. The slag and flue gas in the furnace gas can be settled. The sedimentation water is filtered, and the gas is discharged from the sedimentation water in the form of bubbles. The top of the treatment tank 301 is provided with a connecting shell 306, and the bottom of the connecting shell 306 is connected to an exhaust pipe 307. The exhaust pipe 307 passes through the treatment tank 301 and is connected to the exhaust chamber. The connecting shell 306 is provided with a duct fan 308. By starting the duct fan 308, the gas inside the exhaust chamber can be driven through the exhaust pipe 307 to be discharged into the connecting shell 306. This creates a negative pressure inside the exhaust chamber, so that the gas filtered by the sedimentation water is introduced into the exhaust chamber through the vent and discharged into the connecting shell 306. This reduces the pollution of the atmosphere caused by the smoke and slag discharged with the furnace gas. At the same time, the negative pressure can accelerate the process of furnace gas and smoke being discharged from the furnace body 1. During this process, the slag and smoke can gradually settle at the bottom of the sedimentation water. The sediment can be discharged and treated uniformly by opening the valve of the discharge pipe 304.

[0032] like Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 7 As shown, the preheating structure 4 includes a liquid storage tank 401 disposed between the furnace body 1 and the processing tank 301. The liquid storage tank 401 is filled with a heat exchange medium. A pump body 402 is disposed inside the liquid storage tank 401. A heat exchange tube 403 is connected to the top of the pump body 402. One end of the heat exchange tube 403 passes through the liquid storage tank 401 and the connecting box 305 and is connected to a heat conduction tube 404. The heat exchange tube 403 is distributed in a serpentine pattern inside the connecting box 305. The serpentine distribution of the heat exchange tube 403 can increase the contact area with the furnace gas, thereby enhancing the heat exchange effect. The other end of the heat conduction tube 404 spirals around three connecting pipes 203 and is connected to the liquid storage tank 401. The liquid level of the heat exchange medium is lower than the connection between the heat conduction tube 404 and the liquid storage tank 401. By starting the pump body 402, the heat exchange medium can be introduced into the interior of the heat exchange tube 403 under the action of the pump body 402. The heat from the furnace gas passing through the connection box 305 is absorbed by the heat exchange medium in the heat exchange tube 403, reducing the heat introduced into the flue gas treatment structure 3. This reduces the amount of water vapor discharged from the sedimentation water due to the high temperature of the furnace gas, thus reducing the loss of sedimentation water and lowering the operating cost. Simultaneously, the heat exchange medium, after absorbing heat, can be introduced into the heat conduction tube 404 through the heat exchange tube 403. It can then exchange heat with the connecting tube 203 in contact with the heat conduction tube 404, preheating the gas flowing inside. The preheated gas reduces its impact on the internal temperature of the furnace body 1, preventing the temperature inside the furnace body 1 from dropping due to the low gas temperature during gas addition, which is detrimental to copper refining. This improves resource utilization. The heat exchange medium after heat exchange is returned to the storage tank 401 through the heat conduction tube 404 to form a cycle.

[0033] In use, this invention involves adding raw materials through the charging port 101 after closing the furnace door, followed by copper refining. During the refining process, according to the different steps of smelting, oxidation, and reduction, combustion-supporting gas, oxidant, and reducing agent are injected through the injection structure 2 to facilitate these steps. During gas addition, the added gas causes the copper surface to surge, ensuring thorough mixing with the copper. The inclined surface of the baffle 212 guides the gas, causing it to flow downwards, thus increasing the contact area between the gas and the melt, allowing for a more complete reaction. During the slag removal stage, the annularly distributed injection structure 2 allows the introduced airflow to blow away the slag on the copper surface, and the airflow further enhances the slag removal process. This allows the molten copper surface to surge away from the injection structure 2, thereby accelerating the movement of slag towards the feed port 101. The slag is then removed by a slag rake, completing the slag removal process. Simultaneously, the surging molten copper surface carries slag and some molten copper into the collection box 102. The molten copper can be guided back through the through hole 103 for further refining, while the slag is retained inside the collection box 102 for easier and more uniform slag removal, reducing the difficulty of slag removal and enhancing the performance. When gas addition stops, the combined action of the spring 210, sealing ring 209, and connecting plate 211 resets the stop block 212, preventing the sealing ring 213 from connecting to the furnace body 1. This prevents some slag and dust from entering the installation pipe when no gas is added. When blockage occurs inside the 202 and connecting pipe 203, the sealing ring 209 can re-seal after resetting, improving the anti-blocking effect. Simultaneously, some adhered slag can only adhere to the surface of the baffle 212, and can be pushed out and cleared by the baffle 212 when gas is introduced, maintaining good connectivity of the installation pipe 202. During gas introduction, a gas film can be formed under the flow of gas to prevent slag and dust from entering the interior of the installation pipe 202. By setting the dust treatment structure 3, slag and dust in the furnace gas can be filtered by sedimentation water, reducing the pollution of the atmosphere caused by dust and slag discharged with the furnace gas. At the same time, under negative pressure, the process of furnace gas and dust being discharged from the furnace body 1 can be accelerated. Slag and dust can gradually settle at the bottom of the settling water. The sediment can be discharged and treated uniformly by opening the valve of the discharge pipe 304. At the same time, under the action of the preheating structure 4, the heat in the furnace gas passing through the connecting box 305 can be absorbed by the heat exchange medium in the heat exchange tube 403, reducing the heat introduced into the dust treatment structure 3. This reduces the situation where a large amount of water vapor is discharged from the settling water due to the high temperature of the furnace gas, thus reducing the loss of settling water and reducing the cost of use. Furthermore, the addition of gas is preheated by the cooperation of the heat exchange tube 403 and the heat conduction tube 404, which avoids the situation where the temperature inside the furnace body 1 drops due to the low temperature of the gas during the gas addition process, which is not conducive to copper liquid refining, and improves the resource utilization rate.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
