Description

Technical Field

[0001] The present application relates to the technical field of recycled copper casting, and in particular to a recycled copper anode plate casting line and a production process thereof. Background Art

[0002] Recycled copper is the product of remelting recycled scrap copper, which achieves the reuse of resources. Anode plates can be cast from recycled copper.

[0003] The existing invention patent application with publication number CN103170610A discloses a device for casting an anode copper mold using a tundish of a double-mold disc casting machine and a casting method thereof. The molten copper flows out of the anode furnace and flows into a tundish with a tilting device through a chute. The tundish tilts and pours the molten copper into the copper anode plate copper mold casting mold. The flow rate of the molten copper is controlled by adjusting the tilting angle of the tundish. When the molten copper fills the copper anode plate copper mold casting mold cavity, the central control room switch is closed, the tundish returns to the horizontal waiting position, the upper and lower movable doors of the tundish copper mold casting port are closed, and the upper and lower movable doors of the anode copper casting port are opened. The tundish begins to alternately cast anode plates into the double-mold casting disc system on both sides. After the copper anode plate copper mold has cooled for 6 to 15 minutes, the crane lifts the copper anode plate copper mold casting mold to a safe area to remove the mold.

[0004] With regard to the above-mentioned related technologies, the inventors believe that when pouring molten copper into the mold, the disc needs to stop rotating, which is inefficient. On the other hand, the driving source that drives the disc to rotate needs to be started and stopped frequently. The total weight of the disc and the multiple molds on it is large, and the inertia of the disc's rotation and stopping is also large, which makes the driving source easily damaged. Summary of the invention

[0005] The present application provides a recycled copper anode plate casting line and a production process thereof, which can complete the casting of all molds without stopping the rotation of the disc, thereby improving production efficiency, being more friendly to the driving source that drives the rotation of the disc, and increasing the service life of the driving source.

[0006] The present application provides a recycled copper anode plate casting line, which adopts the following technical solution:

[0007] A casting line for recycled copper anode plates comprises a runner and a frame, wherein the frame is provided with a driving source and a disc driven to rotate by the driving source, a plurality of moulds are distributed circumferentially on the disc, a base is fixed beside the frame, the base is rotatably connected to a driven gear, an outer gear ring meshing with the driven gear is fixed to the outer wall of the disc, a rotating column is fixed to the center of the driven gear, a hopper is rotatably connected to the rotating column, a torsion spring is provided between the hopper and the rotating column, an arc-shaped notch is provided on the top of the base facing the side of the disc, a dumping plate is fixed to the top edge of the hopper, the elastic force of the torsion spring drives the dumping plate to be pressed against the top surface of the base, and the bottom surface of the dumping plate is in sliding contact with the top of the base and the inner wall of the notch.

[0008] By adopting the above technical solution, the driving source drives the outer gear ring and the disc to rotate, and the outer gear ring drives the driven gear to rotate. The driven gear drives the rotating column and the hopper to rotate. When the dumping plate enters the gap, the elastic force of the torsion spring drives the outer bottom wall of the dumping plate to press against the inner wall of the gap, so that the hopper tilts toward one side of the disc, and the hopper pours the molten copper from the dumping plate onto the mold. As the driven gear continues to rotate, the dumping plate leaves the gap, and the hopper returns to a horizontal state and continues to receive the molten copper from the intermediate container. Through the above steps, the cycle runs, and since the outlet position of the dumping plate can move with the mold, the mold can be cast while rotating. The driving source can automatically complete the casting of the regenerated copper anode plate by running at a constant speed, and the casting of all molds can be completed without stopping the rotation of the disc, thereby improving production efficiency, and being more friendly to the driving source that drives the disc to rotate, thereby increasing the service life of the driving source.

[0009] Optionally, the pouring plate is semi-cylindrical, and the bottom surface of the pouring plate is an outer cylindrical surface.

[0010] By adopting the above technical solution, the pouring plate has a better ability to guide copper water, and the arc-shaped bottom surface of the pouring plate can produce a guiding effect, which facilitates the pouring plate to switch and slide between the top of the machine base and the inner wall of the notch.

[0011] Optionally, an intermediate container is provided at the end of the pouring channel, and the intermediate container is provided with a discharge pipe for discharging materials into a hopper.

[0012] By adopting the above technical solution, the molten copper output from the pouring channel is temporarily stored in the intermediate container and the molten copper is kept warm.

[0013] Optionally, a floating block is placed in the intermediate container, and a connecting rod is fixed between the floating block and the upper end of the discharge pipe.

[0014] By adopting the above technical solution, the float block rises and falls with the copper water level, and the depth of the upper end of the discharge pipe in the copper water remains unchanged, thereby ensuring that the pressure and flow rate of the copper water entering the discharge pipe remain unchanged, and the output flow rate of the discharge pipe is kept constant through the float block.

[0015] Optionally, a limiting groove for placing a heavy object is provided on the top surface of the floating block, and a vertically arranged guide rod is fixed to the intermediate container, and the guide rod is slidably connected to the floating block.

[0016] By adopting the above technical solution, the guide rod is used to slide and guide the float block to avoid tilting of the float block. After placing a heavy object in the limit groove, the height position of the float block relative to the liquid surface can be lowered, thereby sinking the upper end of the discharge pipe, increasing the pressure and flow rate of the copper water entering the discharge pipe, thereby adjusting the amount of copper water that finally enters the mold. Through this structure, the amount of copper water in the mold is fine-tuned so that the copper water can fully fill the mold but does not overflow the mold.

[0017] Optionally, the driving source is an electric motor or a hydraulic motor, and a driving gear is fixed to the output end of the driving source, and the driving gear is meshingly connected with the outer gear ring.

[0018] By adopting the above technical solution, when the driving source drives the driving gear to rotate, the driving gear drives the outer gear ring and the disc to rotate.

[0019] Optionally, a support rod is fixed on the frame, the support rod is rotatably connected to a knocking rod, a second torsion spring is provided between the knocking rod and the support rod, and the elastic force of the second torsion spring drives the knocking rod to contact the side wall of the mold.

[0020] By adopting the above technical solution, the knocking rod applies vibration to the mold to avoid uneven distribution of molten copper caused by the tension of molten copper, so that the edges and corners in the mold can be filled with molten copper. As the disc continues to rotate, the mold presses the knocking rod to make it rotate in the opposite direction, and the torsion spring 2 accumulates force. As the mold moves away from the knocking rod, the knocking rod rotates to knock the next mold.

[0021] Optionally, a fan is fixed to the frame, and the fan is located above the disc, with an air outlet end of the fan facing the top surface of the mold after passing through the hopper.

[0022] By adopting the above technical solution, the fan is used to blow air on the surface of the molten copper in the mold to avoid uneven distribution of the molten copper caused by the tension of the molten copper, so that the edges and corners in the mold can be filled with molten copper, and the cooling of the molten copper is accelerated by the fan.

[0023] In a second aspect, the present application provides a production process for a recycled copper anode plate casting line, which adopts the following technical solution:

[0024] A production process of a recycled copper anode plate casting line, using the above-mentioned recycled copper anode plate casting line, comprises the following steps:

[0025] Step S1: The molten copper discharged from the smelting furnace is transported to the intermediate container through the pouring channel, and the intermediate container sends the molten copper into the hopper through the discharge pipe;

[0026] Step S2: The driving source drives the disc to rotate, and the outer gear ring drives the driven gear to rotate through meshing, so that the hopper also rotates. When the pouring plate rotates to one side of the mold, the bottom surface of the pouring plate also enters the notch, so that the hopper tilts toward the pouring plate, thereby pouring the molten copper in the hopper into the mold through the pouring plate;

[0027] Step S3: As the driven gear continues to rotate, the pouring plate leaves the gap, and the hopper returns to a horizontal state, continuing to receive the molten copper from the intermediate container.

[0028] By adopting the above technical solution and the above production process, the casting of the regenerated copper anode plate can be automatically completed. The casting of the regenerated copper anode plate can be automatically completed by running the driving source at a constant speed, and the casting of all molds can be completed without stopping the rotation of the disc.

[0029] Optionally, the following steps are also included:

[0030] Step S4: the mold that has received the molten copper rotates with the disc, the knocking rod knocks the side wall of the mold, the torsion spring 2 accumulates force, and as the mold moves away from the knocking rod, the knocking rod rotates and knocks the next mold;

[0031] Step S5: The fan blows air to the top surface of the mold that has received the molten copper.

[0032] By adopting the above technical solution, the knocking rod and the fan are both located after the mold is cast. The knocking rod is used to apply vibration to the mold, and the fan is used to blow air on the surface of the molten copper in the mold. The two work together to avoid uneven distribution of molten copper caused by the tension of the molten copper, so that the edges and corners in the mold can be filled with molten copper, and the cooling of the molten copper is accelerated by the fan.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. The driving source can automatically complete the casting of the recycled copper anode plate by running at a constant speed. The casting of all molds can be completed without stopping the rotation of the disc, which improves production efficiency;

[0035] 2. It is more friendly to the driving source that drives the disc, avoiding frequent starts and stops and prolonging the service life of the driving source;

[0036] 3. The use of control equipment is minimized, and the casting line can run automatically and stably. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The present application is further described in detail below in conjunction with the accompanying drawings.

[0043] Embodiment 1

[0044] Reference Figure 1 The present embodiment discloses a regenerated copper anode plate casting line, comprising a runner 10 and a frame 1. The runner 10 is a channel for molten copper to be discharged from a smelting furnace. The frame 1 is provided with a driving source 11 and a disc 12 driven to rotate by the driving source 11. The disc 12 is located on the frame 1 and is rotatably connected to the frame 1. A plurality of molds 13 are distributed circumferentially on the disc 12. The mold 13 is firmly mounted on the disc 12 by a clamp, and the mold 13 and the disc 12 will not move spontaneously.

[0045] An outer gear ring 14 is fixed to the outer wall of the disc 12, the driving source 11 is an electric motor or a hydraulic motor, and a driving gear 15 is fixed to the output end of the driving source 11. A base 2 is fixed beside the frame 1, and the base 2 is rotatably connected to a driven gear 21. The outer gear ring 14 is meshed and connected with the driving gear 15 and the driven gear 21 at the same time. When the driving source 11 drives the driving gear 15 to rotate, the driving gear 15 drives the outer gear ring 14 and the disc 12 to rotate, and the outer gear ring 14 drives the driven gear 21 to rotate.

[0046] Reference Figure 2 and Figure 3A rotating column 22 is fixed at the center of the driven gear 21, and a hopper 23 is rotatably connected to the rotating column 22, and its rotation axis is located on a horizontal plane. The inner bottom wall and the outer bottom wall of the hopper 23 are both hemispherical surfaces. A torsion spring 24 is provided between the hopper 23 and the rotating column 22, and the two ends of the torsion spring 24 are respectively fixed to the hopper 23 and the rotating column 22. The machine base 2 wraps around the rotating column 22 and extends upward. The top of the machine base 2 is hemispherical, and the top surface of the machine base 2 is annular and located outside the hopper 23. A circular arc-shaped notch 25 is provided on the side of the top of the machine base 2 facing the disc 12. A pouring plate 26 is fixed to the top edge of the hopper 23. The pouring plate 26 is semi-cylindrical, and the bottom surface of the pouring plate 26 is an outer cylindrical surface. The pouring plate 26 is used to pour out the copper water in the hopper 23.

[0047] The elastic force of the torsion spring 24 drives the dumping plate 26 to press against the top surface of the base 2, and the bottom surface of the dumping plate 26 slides in contact with the top of the base 2 and the inner wall of the notch 25. As the driven gear 21 drives the rotating column 22 and the hopper 23 to rotate, Figure 3 When the pouring plate 26 enters the notch 25, the elastic force of the torsion spring 24 drives the outer bottom wall of the pouring plate 26 to press against the inner wall of the notch 25, so that the hopper 23 tilts toward the side of the disc 12, and the hopper 23 pours the molten copper from the pouring plate 26 onto the mold 13.

[0048] Reference Figure 2 , an intermediate container 3 is provided at the end of the runner 10, through which the copper water output from the runner 10 is temporarily stored and kept warm. The intermediate container 3 can be provided with a heating component to heat the copper water to prevent the copper water from solidifying. The intermediate container 3 is fixed to the steel structure in the workshop and is located at a position higher than the hopper 23. The intermediate container 3 is provided with a discharge pipe 31 for discharging materials into the hopper 23. The discharge pipe 31 runs through the inner bottom of the intermediate container 3. The discharge pipe 31 is an iron metal hose or a corrugated pipe that can be bent. A floating block 32 is placed in the intermediate container 3. A connecting rod 33 is fixed between the floating block 32 and the upper end of the discharge pipe 31. The floating block 32 rises and falls with the copper water level, and the depth of the upper end of the discharge pipe 31 in the copper water remains unchanged, thereby ensuring that the pressure and flow rate of the copper water entering the discharge pipe 31 remain unchanged.

[0049] The float block 32 is made of a light material that is resistant to high temperatures. The float block 32 may be hollow to provide sufficient buoyancy. The top surface of the float block 32 is provided with a limit groove 34 for placing heavy objects. The intermediate container 3 is fixed with a vertically arranged guide rod 35, which is slidably connected to the float block 32, and the guide rod 35 is used to prevent the float block 32 from tilting. The molten copper passing through the runner 10 is intermittent and the flow rate is inconsistent, which will cause the liquid level in the intermediate container 3 to change. Even if the liquid level in the intermediate container 3 is unstable, the output flow of the discharge pipe 31 is kept constant through the float block 32, so that the amount of molten copper delivered to the hopper 23 per unit time is kept constant, thereby ensuring that the amount of molten copper injected into the mold 13 is kept constant each time.

[0050] By setting the limit groove 34, after placing a heavy object in the limit groove 34, the height position of the floating block 32 relative to the liquid surface can be lowered, thereby sinking the upper end of the discharge pipe 31, increasing the pressure and flow rate of the copper water entering the discharge pipe 31, thereby adjusting the amount of copper water that finally enters the mold 13. After the adjustment is completed, the amount of copper water in each mold 13 remains consistent. Through this structure, the amount of copper water in the mold 13 is finely adjusted so that the copper water can fully fill the mold 13 but does not overflow the mold 13.

[0051] Reference Figure 1 and Figure 4 A support rod 4 is fixed on the frame 1, and a knocking rod 41 is rotatably connected to the support rod 4. A torsion spring 42 is provided between the knocking rod 41 and the support rod 4. The two ends of the torsion spring 42 are respectively fixed to the knocking rod 41 and the support rod 4. The elastic force of the torsion spring 42 drives the knocking rod 41 to contact the side wall of the mold 13. A fan 5 is fixed on the frame 1. The fan 5 is located above the disc 12, and the air outlet end of the fan 5 faces the top surface of the mold 13 after passing through the hopper 23.

[0052] The knocking rod 41 and the fan 5 are both located after the casting of the mold 13. The knocking rod 41 applies vibration to the mold 13, and the fan 5 blows air on the surface of the molten copper in the mold 13. The two work together to avoid uneven distribution of the molten copper caused by the tension of the molten copper, so that the edges and corners in the mold 13 can be filled with molten copper, and the cooling of the molten copper is accelerated by the fan 5.

[0053] The implementation principle of a regenerated copper anode plate casting line of the embodiment of the present application is as follows: the driving source 11 drives the disc 12 to rotate clockwise, and the outer gear ring 14 drives the driven gear 21 to rotate through meshing, so that the hopper 23 also rotates. When the pouring plate 26 rotates to one side of the mold 13, the bottom surface of the pouring plate 26 also enters the notch 25, so that the hopper 23 tilts toward the pouring plate 26, thereby pouring the molten copper in the hopper 23 into the mold 13 through the pouring plate 26. As the driven gear 21 continues to rotate, the pouring plate 26 leaves the notch 25, and the hopper 23 returns to a horizontal state and continues to receive the molten copper from the intermediate container 3. Through the above steps, the cycle runs, and since the outlet position of the pouring plate 26 can move with the mold 13, the mold 13 can cast while rotating.

[0054] The driving source 11 can automatically complete the casting of the regenerated copper anode plate by running at a constant speed, and the casting of all the molds 13 can be completed without stopping the rotation of the disc 12, thereby improving the production efficiency, being more friendly to the driving source 11 that drives the disc 12 to rotate, avoiding frequent start and stop, and increasing the service life of the driving source 11. The use of control equipment is minimized, and the casting line can run automatically and stably.

[0055] Embodiment 2

[0056] A production process of a recycled copper anode plate casting line, using a recycled copper anode plate casting line of embodiment 1, comprises the following steps:

[0057] Step S1: the molten copper discharged from the smelting furnace is transported to the intermediate container 3 through the pouring channel 10 , and the intermediate container 3 delivers the molten copper into the hopper 23 through the discharge pipe 31 .

[0058] Step S2: the driving source 11 drives the disc 12 to rotate, and the outer gear ring 14 drives the driven gear 21 to rotate through meshing action, so that the hopper 23 also rotates. When the pouring plate 26 rotates to one side of the mold 13, the bottom surface of the pouring plate 26 also enters the notch 25, so that the hopper 23 tilts toward the pouring plate 26, so that the molten copper in the hopper 23 is poured into the mold 13 through the pouring plate 26.

[0059] Step S3: As the driven gear 21 continues to rotate, the pouring plate 26 leaves the notch 25 , and the hopper 23 returns to a horizontal state, continuing to receive the molten copper from the intermediate container 3 .

[0060] Step S4: the mold 13 receiving the molten copper rotates with the disc 12, and the knocking rod 41 knocks the side wall of the mold 13. As the disc 12 continues to rotate, the mold 13 presses the knocking rod 41 to make it rotate in the opposite direction, and the torsion spring 2 42 accumulates force. As the mold 13 moves away from the knocking rod 41, the knocking rod 41 rotates to knock the next mold 13.

[0061] Step S5: the fan 5 blows air to the top surface of the mold 13 that has received the molten copper.

[0062] Through the above production process, the casting of the recycled copper anode plate is automatically completed.

[0063] 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.
