Description

Technical Field

[0001] The present application relates to the technical field of copper ingot production, and in particular to a copper ingot production line for sanitary ware and a processing technology thereof. Background Art

[0002] Copper ingots are important raw materials for copper parts production. After melting, copper ingots are cast into molds and cooled and solidified to form copper products of various shapes. In addition to smelting copper ore, copper ingots can also be recycled from waste copper and re-smelted into copper ingots to meet the current trend of resource recycling and reuse. Bathroom copper ingots are high-quality copper ingots that need to meet higher purity, lower impurities and bubble counts.

[0003] The existing invention patent application with publication number CN111455200A discloses a preparation method for directly producing environmentally friendly copper ingots for sanitary ware using scrap copper, including the following preparation process: 1. Set the voltage of the smelting furnace to 380-420V, first add iron-removing copper powder and 2# red copper, and then add aluminum rare earth and grain refiner; 2. After it is melted, increase the voltage of the smelting furnace to 780-820V, add crushed copper in batches, and after each batch of crushed copper is melted, lower the voltage to 380-420V to carry out slag removal; finally, add aluminum-boron alloy; 3. After the copper water in step 2 is completely melted, adjust the voltage of the smelting furnace to 580-620V, take the copper water for chemical analysis, and add an appropriate amount of zinc ingots according to the required component ratio.

[0004] With respect to the above-mentioned related technologies, the applicant believes that after the copper scrap is melted, the non-metallic impurities in the copper scrap will float on the surface of the copper liquid to form waste slag. When there is a lot of waste slag, a thick layer will accumulate. At present, the waste slag is cleaned once before the copper liquid is discharged. Since the waste slag cannot be cleaned in time during the smelting process, the waste slag concentration on the top of the copper liquid is too high, which reduces the precipitation rate of new waste slag and has an adverse effect on the quality of the copper ingot. Summary of the invention

[0005] The present application provides a copper ingot production line for sanitary ware and a processing technology thereof, which can clean up the generated waste slag in time and facilitate the precipitation of new waste slag, thereby producing copper ingots of better quality that meet the needs of sanitary ware.

[0006] The present application provides a sanitary copper ingot production line, which adopts the following technical solution: A production line for copper ingots for sanitary ware comprises a smelting furnace, a flow channel, a distributor and a conveyor line, wherein the conveyor line is provided with a plurality of molds for holding molten copper, the smelting furnace comprises a frame and a container arranged in the frame, the frame is provided with an oil cylinder and a horizontal plate driven to rise and fall by the oil cylinder, a reduction motor is fixed on the horizontal plate, a rotating rod is fixed on the output end of the reduction motor, a stirring blade is fixed on the lower end of the side wall of the rotating rod, a sliding sleeve is rotatably connected to the outer side of the rotating rod, a connecting pipe is fixed to the sliding sleeve, the connecting pipe is slidably connected to the frame, a collecting bucket is fixed on the lower end of the connecting pipe, and the opening of the collecting bucket faces one side in the horizontal direction.

[0007] By adopting the above technical solution, the oil cylinder drives the horizontal plate and the reduction motor to move up and down when it is extended and retracted, thereby driving the rotating rod to rise and fall, so as to realize the operation of the stirring blade entering and withdrawing from the container, and can also adjust the height of the collecting bucket to the copper water level. After the reduction motor is started, it drives the rotating rod and the stirring blade to rotate slowly, thereby stirring the material in the container. With the unidirectional rotation of the stirring blade, the waste slag on the surface of the copper water gathers on the inner wall of the container. Since the stirring blade drives the copper water and the waste slag to rotate unidirectionally, and the collecting bucket is stationary relative to the container, the rotating waste slag can spontaneously enter the collecting bucket, and the collecting bucket can automatically collect the waste slag generated during the smelting process, and collect it in real time. Since the waste slag on the copper water can be removed quickly and in real time, the concentration of the waste slag on the top of the copper water is low, which increases the precipitation rate of new waste slag, further reduces the impurity content in the copper water, and thus improves the quality of copper ingots.

[0008] Optionally, the left end of the opening of the collecting hopper is in sliding contact with the inner wall of the container, and the right end of the opening of the collecting hopper is located in the direction from the left end of the opening toward the center of the container.

[0009] By adopting the above technical solution, the opening direction and position of the collecting bucket facilitate the waste residue to enter the collecting bucket.

[0010] Optionally, a suction pipe is passed through the connecting pipe, the lower end of the suction pipe is connected to the collecting bucket, the other end of the suction pipe is connected to the collecting box, an exhaust fan is fixed on the collecting box, the suction end of the exhaust fan is connected to the collecting box, and the air outlet end of the exhaust fan is connected to an exhaust pipe.

[0011] By adopting the above technical solution, after starting the exhaust fan, a vacuum is generated in the collection box, so that the collection bucket is sucked through the suction pipe, and the waste slag in the collection bucket can be pumped into the collection box, thereby realizing automatic slag discharge of the collection bucket. At the same time, the exhaust fan can also extract the waste gas generated in the smelting furnace, avoiding waste gas pollution of the workshop environment, and also helping to improve the quality of molten copper. After closing the doors on both sides of the smelting furnace, the suction of the suction pipe can also form a negative pressure on the molten copper, thereby causing the bubbles in the molten copper to grow larger and precipitate and leave the molten copper from the copper liquid surface, which is beneficial to improving the quality of the molten copper.

[0012] Optionally, a filter is installed in the collection box, and the positions where the suction pipe and the exhaust pipe are connected to the collection box are respectively located on both sides of the filter.

[0013] By adopting the above technical solution, the filter is used to block the waste residue so that the waste residue is retained in the collection box, and the filter is also used to block the dust particles in the exhaust gas to achieve filtration.

[0014] Optionally, a plurality of leakage holes for the copper liquid to pass through are provided at the open lower end of the collecting hopper.

[0015] By adopting the above technical solution, the leakage hole is used for allowing molten copper to pass through, and waste slag is not easy to enter the leakage hole. The leakage hole is used to prevent the molten copper from entering the collecting bucket.

[0016] Optionally, the inner bottom wall of the collecting bucket is rotatably connected to a bottom plate, a support rod is fixed to the bottom of the bottom plate, the support rod passes through the bottom wall of the collecting bucket, a convex rod is fixed to the lower end of the support rod, and the stirring blade can touch the bottom wall of the convex rod when rotating.

[0017] By adopting the above technical solution, the stirring blade rotates slowly, and when the stirring blade hits the bottom wall of the convex rod, it knocks the convex rod to move the convex rod upward. Through the connection of the support rod, the bottom plate rotates upward around its hinge axis, thereby sending the waste slag on the bottom plate into the lower end of the suction pipe. This structure helps the collection bucket to discharge slag in time, avoiding the situation that the suction pipe only absorbs air but not slag. In addition, this structure can prevent copper water from being sucked into the suction pipe by raising the waste slag.

[0018] Optionally, a plurality of ventilation holes are evenly arranged on the surface of the bottom plate.

[0019] By adopting the above technical solution, the vent holes on the bottom plate are used to maintain air circulation to avoid suffocation when the suction pipe is sucking slag.

[0020] Optionally, the stirring blade is spiral-shaped, and when the stirring blade rotates, the copper water in the middle of the container is driven to flow upward.

[0021] By adopting the above technical solution, the stirring blade is spiral-shaped. When the stirring blade rotates, the copper water in the middle of the container is driven to flow upward. The copper water flowing upward then diffuses to the surroundings at the liquid surface, and then sinks near the inner wall of the container, thereby forming a circulation, which makes it easier for the waste slag precipitated in the copper water to float quickly to the liquid surface.

[0022] In a second aspect, the present application provides a processing technology for copper ingots for bathroom use, which adopts the following technical solution: A processing technology for copper ingots for sanitary ware, using the above-mentioned copper ingot production line for sanitary ware, comprises the following steps: Step S1: putting the waste copper together with the additive into a container of a smelting furnace, and heating the container to melt the copper into molten copper; Step S2: lowering the height of the stirring blade and the collecting bucket by means of an oil cylinder so that the lower end of the opening of the collecting bucket contacts the surface of the copper water, and the stirring blade enters the copper water; Step S3: Keep the container heated, start the reduction motor to drive the stirring blade to rotate, the copper liquid rises in the center of the container and then spreads to the surroundings, the collection bucket collects the waste residue, and the exhaust fan is started to absorb the waste residue, and the waste residue is collected in the collection box; Step S3: after smelting is completed, the molten copper in the container is led out to the flow channel; Step S4: The molten copper in the flow channel is input into each mold on the conveyor line through a distributor, and the molten copper in the mold is cooled and solidified to form a copper ingot.

[0023] By adopting the above technical solution, during smelting, the waste slag on the surface of molten copper can be collected and extracted in real time to improve the quality of the molten copper. Through this processing technology, the production of high-quality copper ingots can be completed.

[0024] Optionally, at the conveying line position corresponding to the distributor, the air on the top of the mold is sucked through a fan and an air collecting hood.

[0025] By adopting the above technical solution, the temperature of the molten copper is relatively high when it first enters the mold and smoke will still be emitted. The exhaust gas generated by the molten copper can be extracted through the fan and the air collecting hood to prevent the ash on the exhaust gas from falling on the surface of the copper ingot to reduce its purity, and to prevent the ash in the workshop from falling on the copper ingot.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Since the waste residue on the copper water can be removed quickly and in real time, the concentration of waste residue on the top of the copper water is low, which increases the precipitation speed of new waste residue and further reduces the impurity content in the copper water, thereby improving the quality of copper ingots; 2. Extracting the waste gas in the smelting furnace through the suction pipe can also improve the quality of molten copper; 3. By sucking air through the suction tube, negative pressure is formed on the molten copper, which causes the bubbles in the molten copper to grow larger and precipitate out from the surface of the molten copper, which is beneficial to improving the quality of the copper ingot.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] Embodiment 1

[0031] Reference Figure 1 This embodiment discloses a copper ingot production line for sanitary ware, including a smelting furnace 1, a flow channel 2, a distributor 3 and a conveyor line 4, on which a plurality of molds 41 for holding molten copper are provided. After the scrap copper and other raw materials are melted in the smelting furnace 1, the molten copper is discharged from the smelting furnace 1 to the flow channel 2, and then enters the distributor 3, which sequentially transports the molten copper to each mold 41 on the conveyor line 4, and the molten copper is cooled and solidified in the mold 41 to form a copper ingot product.

[0032] Reference Figure 2 The smelting furnace 1 includes a frame 11 and a container 12 arranged in the frame 11. The container 12 is used to hold the smelted metal. The container 12 is heated by electromagnetic induction. The heating component is a prior art and is not shown in the figure. The container 12 is discharged by dumping. The frame 11 is provided with an oil cylinder 111 and a horizontal plate 112 driven to rise and fall by the oil cylinder 111. A reduction motor 113 is fixed on the horizontal plate 112. A rotating rod 13 is fixed on the output end of the reduction motor 113. The oil cylinder 111 and the rotating rod 13 are both arranged vertically. A stirring blade 131 is fixed on the lower end of the side wall of the rotating rod 13. When the oil cylinder 111 is extended and retracted, the horizontal plate 112 and the reduction motor 113 are driven to move up and down, thereby driving the rotating rod 13 to rise and fall, so as to realize the operation of the stirring blade 131 entering the container 12 and withdrawing the container 12. After the reduction motor 113 is started, it drives the rotating rod 13 and the stirring blade 131 to rotate slowly, thereby stirring the material in the container 12.

[0033] The stirring blade 131 is spiral-shaped. When the stirring blade 131 rotates, the copper water in the middle of the container 12 is driven to flow upward, and the copper water flowing upward then diffuses outward at the liquid surface, and then sinks near the inner wall of the container 12, thereby forming a cycle; and with the unidirectional rotation of the stirring blade 131, the copper water in the container 12 also rotates unidirectionally along the rotation direction of the stirring blade 131. This arrangement facilitates the waste slag precipitated in the copper water to quickly float to the liquid surface and gather at the inner wall of the container 12.

[0034] Reference Figure 1 and Figure 2 The rotating rod 13 is rotatably connected with a sleeve 141, and the sleeve 141 is fixed with a connecting pipe 142, which is L-shaped, and the vertical section of the connecting pipe 142 is slidably connected with the frame 11. The lower end of the connecting pipe 142 is fixed with a collecting bucket 14, and the opening of the collecting bucket 14 faces one side in the horizontal direction. Specifically, the left end of the opening of the collecting bucket 14 is in sliding contact with the inner wall of the container 12, and the right end of the opening of the collecting bucket 14 is located in the direction of the left end of the opening toward the center of the container 12. Since the stirring blade 131 drives the molten copper and the waste residue to rotate in one direction, and the collecting bucket 14 is stationary relative to the container 12, the rotating waste residue can spontaneously enter the collecting bucket 14.

[0035] A suction pipe 151 is inserted into the connecting pipe 142, the lower end of the suction pipe 151 is connected to the collection bucket 14, the other end of the suction pipe 151 is connected to the collection box 15, an exhaust fan 152 is fixed to the collection box 15, the air suction end of the exhaust fan 152 is connected to the collection box 15, and the air outlet end of the exhaust fan 152 is connected to the exhaust pipe 153. A filter screen 154 is installed in the collection box 15, and the filter screen 154 divides the space in the collection box 15. The positions where the suction pipe 151 and the exhaust pipe 153 are connected to the collection box 15 are respectively located on both sides of the filter screen 154. A door panel is hinged on the front of the collection box 15, and the waste residue in the collection box 15 is cleaned by opening the door panel.

[0036] After the exhaust fan 152 is started, a vacuum is generated in the collection box 15, so that the collection bucket 14 is sucked through the suction pipe 151, and the waste slag in the collection bucket 14 can be pumped into the collection box 15. The waste slag is blocked by the filter 154, and the dust particles in the exhaust gas are also blocked by the filter 154, so that the automatic slag discharge of the collection bucket 14 is realized. At the same time, the exhaust fan 152 can also extract the exhaust gas generated in the smelting furnace 1, so as to avoid the exhaust gas from polluting the workshop environment, and also help to improve the quality of the molten copper. After closing the doors on both sides of the smelting furnace 1, the suction of the suction pipe 151 can also form a negative pressure on the molten copper, so as to cause the bubbles in the molten copper to grow larger and precipitate and leave the molten copper from the copper liquid surface, which is beneficial to improve the quality of the molten copper.

[0037] Reference Figure 3 and Figure 4The opening end of the collecting bucket 14 is flared, and a plurality of leakage holes 143 for the copper liquid to pass through are provided at the lower end of the opening of the collecting bucket 14. The leakage holes 143 are small in size, and waste slag is not easy to enter the leakage holes 143. The leakage holes 143 are used to prevent the copper liquid from entering the collecting bucket 14.

[0038] The inner bottom wall of the collecting bucket 14 is rotatably connected to the bottom plate 16, and a plurality of vent holes 161 are evenly arranged on the surface of the bottom plate 16. A support rod 162 is fixed to the bottom of the bottom plate 16, and the support rod 162 penetrates the bottom wall of the collecting bucket 14. The bottom wall of the collecting bucket 14 is provided with an opening whose width is greater than the support rod 162. When the bottom plate 16 rotates around its hinge axis, the support rod 162 will not interfere with the collecting bucket 14. A convex rod 163 is fixed to the lower end of the support rod 162, and the convex rod 163 is a cylindrical rod, and one end of the convex rod 163 extends toward the center of the container 12, and the stirring blade 131 can touch the bottom wall of the convex rod 163 when rotating.

[0039] The stirring blade 131 rotates slowly, and when the stirring blade 131 hits the bottom wall of the protruding rod 163, it knocks the protruding rod 163, so that the protruding rod 163 moves upward, and through the connection of the support rod 162, the bottom plate 16 rotates upward around its hinge axis, so that the waste residue on the bottom plate 16 is sent into the lower end of the suction pipe 151. This structure helps the collection bucket 14 to discharge the residue in time, and avoids the situation that the suction pipe 151 only absorbs air but not the residue. In addition, this structure can prevent the copper liquid from being sucked into the suction pipe 151 by raising the waste residue. Then the bottom plate 16 falls back to a horizontal state under its own gravity, and receives the waste residue entering the collection bucket 14 again. The air vent 161 on the bottom plate 16 is used to maintain air circulation, so as to avoid holding the breath when the suction pipe 151 extracts the residue.

[0040] Reference Figure 5 The distributor 3 is driven to rotate by a motor. The distributor 3 includes a liquid inlet 31 and a plurality of circumferentially distributed liquid outlets 32. The liquid inlet 31 is connected to the end of the flow channel 2. The liquid outlets 32 correspond to each mold cavity on the mold 41 one by one. The molds 41 are chain-connected to form a conveyor belt structure. The motor drives the distributor 3 to rotate at a constant speed. When the liquid outlet 32 ​​rotates to the lowest position, the copper water in the distributor 3 naturally flows out to the corresponding mold 41, realizing automatic copper injection into the mold 41 without the need to set a valve for frequent opening and closing.

[0041] The implementation principle of a sanitary copper ingot production line of the embodiment of the present application is as follows: the waste slag generated during the smelting process can be automatically collected by the collecting bucket 14, and can be collected in real time, and the waste slag in the collecting bucket 14 can be timely extracted through the suction pipe 151. Since the waste slag on the copper water can be removed quickly and in real time, the concentration of the waste slag on the top of the copper water is low, which increases the precipitation speed of new waste slag, further reduces the impurity content in the copper water, and thus improves the quality of the copper ingot. Extracting the waste gas in the smelting furnace 1 through the suction pipe 151 can also improve the quality of the copper water; by exhausting air through the suction pipe 151, a negative pressure is formed on the copper water, thereby causing the bubbles in the copper water to grow larger and precipitate and leave the copper water from the copper water surface, which is beneficial to improving the quality of the copper water.

[0042] Embodiment 2

[0043] A processing technology for copper ingots for sanitary ware, using a sanitary ware copper ingot production line of embodiment 1, comprises the following steps: Step S1: Put the waste copper together with the additive into the container 12 of the smelting furnace 1, and heat the container 12 to melt the copper into molten copper; the additive can be an alloy element, or other additives that improve the quality of copper, or additives that help to precipitate impurities.

[0044] Step S2: lower the height of the stirring blade 131 and the collecting bucket 14 through the oil cylinder 111, so that the lower end of the opening of the collecting bucket 14 contacts the surface of the copper water, and a small amount of the stirring blade 131 can be immersed in the copper water. At this time, the stirring blade 131 enters the copper water.

[0045] Step S3: Keep the container 12 in a heated state, start the reduction motor 113 to drive the stirring blade 131 to rotate, the copper liquid rises in the center of the container 12 and then spreads to the surroundings, the movement of the waste slag is the same, and the waste slag is rotating, the collection bucket 14 collects the waste slag, and the exhaust fan 152 is started to absorb the waste slag, and the waste slag is collected in the collection box 15. The stirring blade 131 knocks the protruding rod 163, so that the bottom plate 16 rotates automatically, so that the waste slag in the collection bucket 14 can be reliably extracted to avoid clogging.

[0046] Step S3: After smelting is completed, the molten copper in the container 12 is discharged to the flow channel 2. Before the molten copper is discharged, the oil cylinder 111 is controlled to extend so that the stirring blade 131 and the collecting bucket 14 are raised and leave the container 12, and then the furnace door of the smelting furnace 1 is opened, and the container 12 is driven by the hydraulic cylinder to rotate and pour, and the discharged molten copper enters the flow channel 2.

[0047] Step S4: The molten copper in the flow channel 2 is input into each mold 41 on the conveyor line 4 through the distributor 3. The molten copper in the mold 41 is cooled and solidified to form a copper ingot for bathroom use.

[0048] Reference Figure 6At the position of the conveyor line 4 corresponding to the distributor 3, the air on the top of the mold 41 is sucked by the fan 51 and the air collecting hood 5, and the exhaust gas is discharged from the upper pipe. When the molten copper just enters the mold 41, the temperature is relatively high and smoke will still be emitted. The fan 51 and the air collecting hood 5 can extract the exhaust gas generated by the molten copper to prevent the ash on the exhaust gas from falling on the surface of the copper ingot to reduce the purity, and also to prevent the ash in the workshop from falling on the copper ingot.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
