Description

Technical Field

[0001] This invention belongs to the field of solid waste treatment equipment, and more specifically, relates to a crushing and recycling equipment and process for electrolytic copper slag. Background Technology

[0002] Electrolytic copper slag is a solid waste generated during the copper electrolytic refining process. It mainly originates from the separation and residue of impurities in the anode plate under the action of electric current. This type of residue typically contains 5% to 9% copper, and current technologies mostly use recycling furnaces for smelting to achieve copper recovery and utilization.

[0003] Chinese patent CN117225858B discloses a recycling equipment and process for electrolytic copper slag. The copper slag is crushed by a crushing roller mechanism. The crushed copper slag falls onto a guide plate and is guided by the guide plate to fall into one side of the storage tank. At this time, the copper slag on both sides of the feeding block will slide evenly into the interior of the recycling furnace body along the first inclined feeding port and the second feeding port, respectively.

[0004] However, the patented equipment still has certain limitations: First, the lack of an interception and screening mechanism may result in insufficient crushing of some copper slag, thus affecting the subsequent smelting efficiency; Second, although a dual-feed port design is adopted, the copper slag may still be unevenly distributed in the recycling furnace, which will also have an adverse effect on the uniformity of copper slag distribution and processing efficiency during the smelting process.

[0014] A crushing and recycling device for electrolytic copper slag, comprising the aforementioned solid waste recycling and processing device.

[0015] A crushing and recycling process for electrolytic copper slag, the specific steps of which are as follows: Electrolytic copper slag is fed into the crushing box, where it is crushed by the crushing components. The crushed slag falls onto a screen plate, while a reciprocating vibration component drives the screen plate to vibrate repeatedly within the crushing box, thus screening the slag. Slag with the correct particle size falls through the screen holes onto the receiving part of the lifting and conveying component below. The lifting and conveying component then sequentially conveys the slag along the receiving part, the inclined lifting part, and the dropping part until it is dropped onto a guide plate. The slag continues to slide downwards along the guide plate into the recovery furnace. Simultaneously, a reciprocating oscillating component drives the guide plate to oscillate, adjusting its position to evenly distribute the slag within the recovery furnace. Finally, the recovery furnace heats and melts the crushed slag.

[0016] The present invention has the following beneficial effects: 1. In this invention, the electrolytic copper slag is crushed by a crushing mechanism, and then the crushed electrolytic copper slag is lifted and transported to a recycling furnace by a conveying mechanism. The recycling furnace then smelts and recycles the crushed electrolytic copper slag. Thus, through the cooperation of the crushing mechanism, the conveying mechanism and the recycling furnace, the electrolytic copper slag can be automatically recycled, making the recycling of electrolytic copper slag more convenient and faster.

[0017] 2. In this invention, the electrolytic copper slag, after being crushed by the crushing component, falls downward onto the screen plate. Simultaneously, the reciprocating vibration component drives the screen plate to vibrate reciprocally within the crushing chamber, thereby enabling the screen plate to vibrate and screen the crushed electrolytic copper slag. Electrolytic copper slag with qualified particle size after crushing falls through the screen holes of the screen plate onto the lifting and conveying component below, which then transports it into the recovery furnace. Thus, the interception and screening by the screen plate can remove large-particle electrolytic copper slag that is not thoroughly crushed, which is beneficial to improving the smelting and recovery efficiency of the subsequent electrolytic copper slag. Furthermore, the vibrating screening by the screen plate not only improves the screening efficiency but also evenly distributes the crushed electrolytic copper slag that falls onto the screen plate onto the lifting and conveying component below, thereby improving the uniformity of the distribution of electrolytic copper slag in the subsequent recovery furnace, and thus improving the heating uniformity and smelting efficiency of the electrolytic copper slag in the recovery furnace.

[0018] 3. In this invention, when the lifting and conveying assembly conveys the electrolytic copper slag to the guide plate, the reciprocating oscillating assembly drives the guide plate to oscillate back and forth to adjust the dropping position of the guide plate, so that the guide plate can evenly convey and spread the electrolytic copper slag in the recycling furnace. Thus, the combination of sieving by the sieve plate and the oscillating dropping by the guide plate can further improve the uniformity of the distribution of electrolytic copper slag in the recycling furnace and the smelting efficiency.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1 Please see Figure 1 , Figure 2 As shown, this embodiment is a crushing and recycling device for electrolytic copper slag, including a crushing mechanism 1, a conveying mechanism 2, and a recycling furnace 3. The crushing mechanism 1 includes a crushing box 11, a crushing component, and a reciprocating vibration component. The crushing component is installed inside the crushing box 11. A screen plate 13 located below the crushing component is also installed inside the crushing box 11. The reciprocating vibration component can drive the screen plate 13 to reciprocate within the crushing box 11. The conveying mechanism 2 includes a lifting conveying component, a reciprocating swing component, and a guide plate 23. The lifting conveying component includes a receiving part, an inclined lifting part, and a dropping part arranged in sequence. The receiving part is located below the screen plate 13. The guide plate 23 is rotatably installed below the dropping end of the dropping part. The reciprocating swing component can drive the guide plate 23 to reciprocate and swing to drop material. The recycling furnace 3 is located below the guide plate 23.

[0026] When the electrolytic copper slag crushing and recycling equipment is working, the electrolytic copper slag is fed into the crushing box 11. The crushing components crush the slag, and the crushed slag falls onto the screen plate 13. Simultaneously, the reciprocating vibration component drives the screen plate 13 to vibrate reciprocally within the crushing box 11, thus screening the crushed slag. Electrolytic copper slag with a suitable particle size falls through the screen holes of the screen plate 13 onto the receiving part of the lifting and conveying component below. The electrolytic copper slag is conveyed sequentially from the receiving part, the inclined lifting part and the dropping part by the lifting and conveying assembly until it is dropped from the dropping part onto the guide plate 23. It continues to slide down the guide plate 23 into the recycling furnace 3. At the same time, the reciprocating swing assembly drives the guide plate 23 to swing back and forth to adjust the dropping position of the guide plate 23 so that the guide plate 23 can evenly convey and spread the electrolytic copper slag into the recycling furnace 3. Finally, the recycling furnace 3 heats and melts the crushed electrolytic copper slag. The combination of crushing mechanism 1, conveying mechanism 2, and recycling furnace 3 enables automatic recycling of electrolytic copper slag, making the recycling process more convenient and efficient. The sieve plate 13 removes large-particle electrolytic copper slag that is not thoroughly crushed, which helps improve the efficiency of subsequent smelting and recycling of electrolytic copper slag. Furthermore, the vibrating sieve plate 13 not only improves the screening efficiency but also allows the crushed electrolytic copper slag falling onto the sieve plate 13 to be evenly distributed onto the lifting conveying assembly below. Combined with the guide plate 23 at the end of the lifting conveying assembly, the uniformity of the distribution of electrolytic copper slag in the recycling furnace 3 and the smelting efficiency are greatly improved.

[0027] Example 2 Please see Figure 1 , Figure 4 , Figure 7 As shown, the difference between this embodiment and the above embodiment is that the crushing mechanism 1 further includes a support 12, the crushing box 11 is fixedly installed on the support 12, the crushing component includes a rotary drive unit and two crushing rollers 111, the two crushing rollers 111 are arranged in parallel and rotatably installed inside the crushing box 11, and crushing teeth 112 are fixedly installed on the surface of the two crushing rollers 111. A guide ramp 113 inclined downward toward the crushing rollers 111 is also installed on the side wall of the crushing box 11. The rotary drive unit can drive the two crushing rollers 111 to rotate in opposite directions. The rotary drive unit includes a crushing motor 114, a reduction gearbox 115 and two synchronous gears 116. The two synchronous gears 116 are respectively fixedly installed at the ends of the two crushing rollers 111, and the two synchronous gears 116 are meshed and connected. The crushing motor 114 and the reduction gearbox 115 are both fixedly installed on the support 12. The output end of the crushing motor 114 is connected to the input end of the reduction gearbox 115, and the output end of the reduction gearbox 115 is connected to the end of one of the crushing rollers 111.

[0028] When the crushing mechanism 1 is working, the electrolytic copper slag is fed into the crushing box 11. The guide ramp 113 on the inner wall of the crushing box 11 can guide and convey the electrolytic copper slag, so that the electrolytic copper slag falls into the gap between the two crushing rollers 111. Then, the crushing motor 114 drives the crushing rollers 111, which are connected to the reduction gearbox 115, to rotate. At the same time, the crushing rollers 111 drive the synchronous gears 116 at their ends to rotate. Then, the synchronous gears 116 mesh and drive the other synchronous gears 116 to rotate synchronously in the opposite direction. Thus, the two crushing rollers 111 can be driven to rotate in opposite directions through the rotation drive unit to crush the electrolytic copper slag in the crushing box 11. The crushed electrolytic copper slag falls down onto the screen plate 13 below, where it is screened.

[0029] Example 3 Please see Figure 1 , Figure 2 , Figures 5-7 , Figure 11 , Figure 12 As shown, the difference between this embodiment and the above embodiments lies in that the reciprocating vibration assembly includes a vibration drive unit and a transmission shaft 18. The transmission shaft 18 is rotatably mounted on the bracket 12, and an eccentric shaft 19 is fixedly mounted on the transmission shaft 18. A push-pull rod 110 is rotatably mounted on the eccentric shaft 19, and one end of the push-pull rod 110 is rotatably connected to the outer end of the screen plate 13. The vibration drive unit is drively connected to the transmission shaft 18 so that the vibration drive unit can drive the transmission shaft 18 to rotate continuously. The vibration drive unit includes a screening motor. The screen motor 14 is fixedly mounted on the support 12, and the output end of the screen motor 14 is fixedly mounted with the drive wheel 15. The driven wheel 16 is fixedly mounted on the drive shaft 18. The drive wheel 15 and the driven wheel 16 are connected by a drive belt 17. The support 12 is also fixedly mounted with a slide rail 118 located below the crushing box 11 and inclined. The screen plate 13 is slidably mounted in the slide rail 118. The lower end of the support 12 is equipped with a recycling box 117 located on the inclined downward side of the screen plate 13.

[0030] When the crushed electrolytic copper slag is screened, the screening motor 14 drives the drive wheel 15 to rotate, and the drive wheel 15 drives the driven wheel 16 to rotate through the transmission belt 17, thereby driving the transmission shaft 18 to rotate. When the transmission shaft 18 rotates, it drives the eccentric shaft 19 to make a circular motion, so that the eccentric shaft 19 can drive the screen plate 13 to slide back and forth along the slide rail 118 through the push-pull rod 110, thereby causing the screen plate 13 to vibrate and screen. The qualified electrolytic copper slag is evenly fed to the lifting and conveying assembly below, while the large-diameter electrolytic copper slag that is not completely crushed moves downward along the surface of the inclined screen plate 13 and is fed into the recycling box 117. The recycling box 117 recovers the unqualified electrolytic copper slag and crushes it again.

[0031] Example 4 Please see Figures 8-12 As shown, the difference between this embodiment and the above embodiments is that the lifting and conveying assembly includes a conveyor frame 22, which includes a lower horizontal conveyor frame, a lifting conveyor frame, and an upper horizontal conveyor frame. The lower horizontal conveyor frame is fixedly installed below the crushing box 11. A belt conveyor line is installed inside the conveyor frame 22, which is arranged along the lower horizontal conveyor frame, the lifting conveyor frame, and the upper horizontal conveyor frame. The belt conveyor line includes a conveying drive unit, a conveyor belt 21, a driven roller 24, a driving roller 29, and multiple limiting guide rollers. The driven roller 24 and the driving roller 29 are rotatably installed at both ends of the conveyor frame 22, and the conveyor belt 21 is driven between the driven roller 24 and the driving roller 29. The multiple limiting guide rollers are rotatably installed at the bottom of the conveyor frame 22. The connection points of the flat conveyor frame and the lifting conveyor frame, as well as the bends connecting the lifting conveyor frame and the upper horizontal conveyor frame, are designed to guide and limit the conveyor belt 21 at the bends, allowing the conveyor belt 21 to be arranged sequentially along the lower horizontal conveyor frame, the lifting conveyor frame, and the upper horizontal conveyor frame. The conveying drive unit can drive the active roller 29 to rotate, so that the active roller 29 and the driven roller 24 cooperate to drive the conveyor belt 21 to move cyclically. The conveying drive unit includes a conveying motor 210 and a transmission wheel 212. The output end of the conveying motor 210 is fixedly mounted with a drive wheel 211, and the transmission wheel 212 is fixedly mounted at the end of the active roller 29. The drive wheel 211 and the transmission wheel 212 are connected by a drive belt 213.

[0032] The electrolytic copper slag after screening by the sieve plate 13 falls and is conveyed onto the conveyor belt 21 in the lower horizontal conveyor frame. Then, the drive wheel 211 is driven to rotate by the conveyor motor 210. The drive wheel 211 then drives the transmission wheel 212 to rotate through the drive belt 213. Thus, the transmission wheel 212 drives the drive roller 29 to rotate. When the drive roller 29 rotates, it can drive the conveyor belt 21 to move cyclically along the lower horizontal conveyor frame, the lifting conveyor frame and the upper horizontal conveyor frame through frictional resistance. This allows the conveyor belt 21 to lift and convey the electrolytic copper slag on it upward. At the same time, the conveyor belt 21 also drives the driven roller 24 to rotate synchronously through frictional resistance.

[0033] Furthermore, the surface of the conveyor belt 21 is provided with anti-slip texture, which can improve the anti-slip performance of the surface of the conveyor belt 21 and prevent the electrolytic copper slag from sliding down the inclined surface of the conveyor belt 21 when the conveyor belt 21 lifts and transports the electrolytic copper slag upward along the lifting conveyor frame, thus ensuring the stable operation of the lifting and transporting process of the electrolytic copper slag.

[0034] Example 5 Please see Figure 1 , Figure 3 , Figure 8 , Figure 10 , Figures 13-15As shown, the difference between this embodiment and the above embodiment is that the reciprocating oscillating assembly includes two sets of transmission units and two sets of oscillating drive units. The two sets of oscillating drive units are rotatably installed on both sides below the end of the upper horizontal conveyor frame. One end of the oscillating drive unit is connected to the guide plate 23 through a transmission unit, and the other end of the oscillating drive unit is connected to the driven roller 24 through a transmission unit. When the conveying drive unit drives the active roller 29 and the driven roller 24 to rotate and drive the conveyor belt 21 to circulate, the driven roller 24 drives the oscillating drive unit to run synchronously through the transmission unit, so that the oscillating drive unit drives the guide plate 23 to oscillate back and forth to drop the material.

[0035] Through the cooperation of the transmission unit and the swing drive unit, when the conveyor belt 21 drives the driven roller 24 to rotate in a cyclic conveying motion, the guide plate 23 is automatically driven to swing back and forth, so that the dropping end of the guide plate 23 moves back and forth left and right above the recycling furnace 3. When the dropping end of the guide plate 23 moves from left to right above the recycling furnace 3, the guide plate 23 gradually drops and lays the electrolytic copper slag from left to right into the recycling furnace 3. Correspondingly, when the dropping end of the guide plate 23 moves from right to left above the recycling furnace 3, the guide plate 23 gradually drops and lays the electrolytic copper slag from right to left into the recycling furnace 3. This allows the guide plate 23 to evenly drop and lay the electrolytic copper slag into the recycling furnace 3, thereby improving the heating uniformity and smelting efficiency of the electrolytic copper slag in the recycling furnace 3.

[0036] Furthermore, the oscillating drive unit includes a rotating shaft 28, one end of which is connected to the transmission unit, and the other end of which is fixedly mounted with a cam 215. The protruding end of the cam 215 is rotatably connected to a connecting rod 214, and one end of the connecting rod 214 is rotatably connected to the back of the guide plate 23. The transmission unit includes a main pulley 25 and a secondary pulley 27. The main pulley 25 is fixedly mounted on the end of the driven roller 24, and the secondary pulley 27 is fixedly mounted on the end of the rotating shaft 28. The main pulley 25 and the secondary pulley 27 are connected by a transmission belt 26. When the driven roller 24 rotates, it drives the main pulley 25 to rotate synchronously. Then, the main pulley 25 drives the auxiliary pulley 27 to rotate through the transmission belt 26. The auxiliary pulley 27 drives the rotating shaft 28 and the cam 215 to rotate. When the cam 215 rotates, it can drive the guide plate 23 to swing back and forth through the connecting rod 214, so that the guide plate 23 can evenly drop and spread the electrolytic copper slag into the recycling furnace 3.

[0037] Example 6 This embodiment describes a crushing and recycling process for electrolytic copper slag, with the following specific steps: Electrolytic copper slag is fed into the crushing box 11, where it is crushed by the crushing assembly. The crushed slag falls onto the screen plate 13, while the reciprocating vibration assembly drives the screen plate 13 to vibrate back and forth within the crushing box 11. This allows the screen plate 13 to screen the crushed slag. Electrolytic copper slag with the correct particle size after crushing falls through the screen holes of the screen plate 13 onto the receiving part of the lifting and conveying assembly below. The lifting and conveying assembly then sequentially conveys the slag along the receiving part, the inclined lifting part, and the dropping part until it is dropped onto the guide plate 23. The slag continues to slide down the guide plate 23 into the recycling furnace 3. Simultaneously, the reciprocating oscillating assembly drives the guide plate 23 to oscillate back and forth to adjust its dropping position, ensuring that the guide plate 23 can evenly convey and spread the electrolytic copper slag within the recycling furnace 3. Finally, the recycling furnace 3 heats and melts the crushed electrolytic copper slag.

A belt conveyor line is installed inside the conveyor frame and is laid out along the lower horizontal conveyor frame, the lifting conveyor frame, and the upper horizontal conveyor frame.

6. A solid waste recycling and processing device according to claim 5, characterized in that: The belt conveyor line includes a conveyor drive unit, a conveyor belt, a driven roller, a driving roller, and multiple limiting guide rollers. The driven roller and the driving roller are rotatably mounted at both ends of the conveyor frame. The conveyor belt is driven and mounted between the driven roller and the driving roller. The multiple limiting guide rollers are rotatably mounted at the connection between the lower horizontal conveyor frame and the lifting conveyor frame, as well as at the connection bend between the lifting conveyor frame and the upper horizontal conveyor frame, so that the limiting guide rollers can guide and limit the conveyor belt at the connection bend, allowing the conveyor belt to be arranged sequentially along the lower horizontal conveyor frame, the lifting conveyor frame, and the upper horizontal conveyor frame. The conveyor drive unit can drive the driving roller to rotate, so that the driving roller and the driven roller cooperate to drive the conveyor belt to move cyclically.

7. A solid waste recycling and processing device according to claim 6, characterized in that: The reciprocating oscillating assembly includes two sets of transmission units and two sets of oscillating drive units. The two sets of oscillating drive units are rotatably installed on both sides below the end of the upper horizontal conveyor frame. One end of the oscillating drive unit is connected to the guide plate, and the other end of the oscillating drive unit is connected to the driven roller through the transmission unit. When the conveyor drive unit drives the active roller and the driven roller to rotate and drive the conveyor belt to circulate, the driven roller drives the oscillating drive unit to run synchronously through the transmission unit, so that the oscillating drive unit drives the guide plate to oscillate back and forth to drop the material.

8. A solid waste recycling and processing device according to claim 7, characterized in that: The swing drive unit includes a rotating shaft, one end of which is connected to a transmission unit, and the other end of which is fixedly mounted with a cam. The convex end of the cam is rotatably connected to a connecting rod, and one end of the connecting rod is rotatably connected to the back of the guide plate.

9. A crushing and recycling device for electrolytic copper slag, comprising the solid waste recycling and processing device as described in any one of claims 1-8.

10. A crushing and recycling process for electrolytic copper slag, using the solid waste recycling and treatment device as described in any one of claims 1-8, characterized in that, The specific steps are as follows: Electrolytic copper slag is fed into the crushing box, where it is crushed by the crushing components. The crushed slag falls onto a screen plate, while a reciprocating vibration component drives the screen plate to vibrate repeatedly within the crushing box, thus screening the slag. Slag with the correct particle size falls through the screen holes onto the receiving part of the lifting and conveying component below. The lifting and conveying component then sequentially conveys the slag along the receiving part, the inclined lifting part, and the dropping part until it is dropped onto a guide plate. The slag continues to slide downwards along the guide plate into the recovery furnace. Simultaneously, a reciprocating oscillating component drives the guide plate to oscillate, adjusting its position to evenly distribute the slag within the recovery furnace. Finally, the recovery furnace heats and melts the crushed slag.
