Description

Technical Field

[0001] The present invention relates to the technical field of black powder transportation, and particularly to a multi-channel air transportation system for black powder of waste lithium batteries. Background Art

[0002] The battery mainly includes copper foil, aluminum foil, separator, electrolyte, binder and black powder. With the booming development of the new energy field, the recycling of waste lithium batteries has become the focus of the industry. At present, the recycling of lithium batteries mainly involves crushing the battery and then separating and recycling copper, aluminum and black powder. Therefore, in order to realize the recycling and sorting of copper, aluminum and black powder, after the waste lithium battery is crushed by a crusher, it usually needs to be pyrolyzed at high temperature to remove the separator, electrolyte and binder, and then the remaining materials (copper, aluminum and black powder) are separated and recycled.

[0003] There are the following problems in the existing transportation of black powder of lithium batteries: 1. Nowadays, the pipeline transportation of black powder is carried out in a single channel or multiple channels, which are separated and cannot be combined, so that the variable transportation of black powder cannot be carried out; 2. During the transportation process of black powder, agglomeration will occur due to friction with the pipeline or itself. At this time, the black powder will form a mass and cause blockage, affecting the subsequent transportation and treatment. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By replacing the original position of the movable square pipe with a replacement pipe and blocking the transition pipe with a flow blocking plate, the black powder entering the inside of the material distribution pipe will not be discharged from the outlet pipe, thus preparing for the subsequent multi-transport channels and single-output channels.

[0022] 2. By the plugging plate protruding outwards from the replacement pipe and the replacement pipe squeezing and moving the movable square pipe upwards to replace the position of the movable square pipe, the material distribution pipe will be connected and communicated with the main material pipe, thus playing a role in inputting black powder through multiple channels and outputting through a single channel. In addition, when the hydraulic rod is not started, the material distribution pipe and the main material pipe will not be connected, thus playing a role in inputting through multiple channels and outputting through multiple channels.

[0023] 3. When there is air flow, the stainless steel ice cubes will be revealed and play a role in cooling the black powder during the conveying process. Appropriate temperature reduction can reduce the thermal movement of the black powder and lower the probability of collision and combination between particles, so as to avoid the black powder adhering together due to overheating in the pipe and causing agglomeration.

[0024] 4. The diverter plate fixedly connected to the other end of the first magnet will deflect downward through the second support, so that the black powder flowing out of the feeding pipe will first fall on the diverter plate and then enter the main material pipe, avoiding directly falling on the main material pipe and causing black powder to fly, increasing the probability of agglomeration. At the same time, the downward deflection of the diverter plate will reduce the degree of black powder flying.

[0025] 5. The air flow enters the leakage receiving pipe, so as to play a role in receiving and recycling the leaked black powder. At the same time, the size of the hole generated by the corrosion of the main material pipe can be judged by the amount of black powder discharged from the leakage receiving pipe.

DETAILED DESCRIPTION

[0041] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 14 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, it includes a combined mechanism 1, which is used for the assembly and connection processing of multiple pipelines;

[0043] A conveying mechanism 2, which is used for the transmission processing of black powder. A feeding pipe 3 is fixedly installed at the top of the conveying mechanism 2;

[0044] A flow splitting mechanism 4, which is used for the flow splitting and conveying processing of air flow;

[0045] An anti-clumping mechanism 5, which is used to prevent black powder from aggregating into lumps;

[0046] The combined mechanism 1 is arranged above the conveying mechanism 2. The anti-clumping mechanism 5 is symmetrically connected to both sides of the conveying mechanism 2. The flow splitting mechanism 4 is fixedly installed on the outside of the conveying mechanism 2.

[0047] Among them, the combined mechanism 1 includes a material distribution pipe 11. A vertical rail 12 is fixedly connected to the top of the material distribution pipe 11. A slide bar 13 is slidably fitted inside the vertical rail 12. A movable square pipe 14 is fixedly connected to the bottom of the slide bar 13. The outside of the movable square pipe 14 is slidably fitted with the material distribution pipe 11. A transition pipe 15 is slidably fitted on one side of the movable square pipe 14 away from the material distribution pipe 11. A discharge pipe 16 is fixedly connected to one end of the transition pipe 15 away from the movable square pipe 14. A first support 17 is fixedly connected to the top of the transition pipe 15. A flow blocking plate 18 is rotatably connected inside the first support 17. Reset elastic strips 19 are symmetrically connected to both ends of the flow blocking plate 18. One end of the reset elastic strip 19 away from the flow blocking plate 18 is fixedly connected to a side plate 10. The side plates 10 are symmetrically connected to both ends of the transition pipe 15.

[0048] A support plate 101 is fixedly connected to the top of the transition pipe 15. A rotating shaft 102 is fixedly connected to the inner side of the support plate 101. A seesaw 103 is rotatably connected to the outer side of the rotating shaft 102. One end of the seesaw 103 is in pressing fit with the top of the movable square pipe 14. The end of the seesaw 103 away from the movable square pipe 14 is in pressing fit with the top of the flow blocking plate 18. An elastic pad 104 is fixedly connected to the outer side of the seesaw 103. One end of the elastic pad 104 is fixedly connected to the outlet pipe 16. The end of the elastic pad 104 away from the outlet pipe 16 is fixedly connected to a top plate 105. The top plate 105 is fixedly connected to the top of the outlet pipe 16. By starting the hydraulic rod 23 and making its output end contract, the material distribution pipe 11 connected to its top end will move downward. At this time, the replacement pipe 205 arranged directly below the movable square pipe 14 will press on it. The replacement pipe 205 is fixed, so under the action of the reaction force, the movable square pipe 14 will move upward along the vertical rail 12 through the slide bar 13, causing the replacement pipe 205 to replace the original position of the movable square pipe 14. The original position of the movable square pipe 14 is the position where it is spliced and interconnected with the material distribution pipe 11. As the movable square pipe 14 moves upward, it will impact the seesaw 103 upward. At this time, the seesaw 103 will deflect counterclockwise through the rotating shaft 102, and the other end of the seesaw 103 will press the flow blocking plate 18 downward, causing the flow blocking plate 18 to deflect downward through the first support 17. Finally, the flow blocking plate 18 will block the opening of the transition pipe 15. The flow blocking plate 18 was initially kept horizontal by the reset elastic strip 19 and will be in a vertical state when being pressed downward by the seesaw 103. In addition, the elastic pad 104 fixedly connected to the outer side of the seesaw 103 is elastic. Therefore, by replacing the original position of the movable square pipe 14 with the replacement pipe 205 and blocking the transition pipe 15 with the flow blocking plate 18, the black powder entering the material distribution pipe 11 will not be discharged from the outlet pipe 16, which serves as a preparation for the subsequent multi-transport channels and single-output channel.

[0049] Such as Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown in the figure, the conveying mechanism 2 includes a main material pipe 21. The top of the main material pipe 21 is fixedly connected to the feeding pipe 3. The bottom of the main material pipe 21 is fixedly connected with a leakage receiving pipe 209. The top of the main material pipe 21 is fixedly connected with a hydraulic rod 23. The top end of the hydraulic rod 23 is fixedly connected to the material distributing pipe 11. One end of the material distributing pipe 11 away from the hydraulic rod 23 is fixedly connected with a square plate 24. The bottom of the square plate 24 is fixedly connected with a piston rod 25. The bottom of the piston rod 25 is inserted into a compensation pipe 26. One end of the compensation pipe 26 away from the piston rod 25 is fixedly connected with a hollow seat 27. One end of the hollow seat 27 away from the compensation pipe 26 is inserted with a moving rod 28. One end of the moving rod 28 away from the hollow seat 27 is fixedly connected with a double-headed rod 29. The inner side of the double-headed rod 29 is fixedly connected with a return spring 20. One end of the return spring 20 away from the double-headed rod 29 is fixedly connected to the outer side of the hollow seat 27.

[0050] The central part of the inner side of the double-headed rod 29 is fixedly connected with a sliding rod 201. The bottom of the sliding rod 201 is slidably fitted with a first rail 202. The first rail 202 is fixedly connected to the top of the main material pipe 21. One end of the double-headed rod 29 away from the moving rod 28 is fixedly connected with a fastener 203. One end of the fastener 203 away from the double-headed rod 29 is fixedly connected with a plugging plate 204. The outer side of the plugging plate 204 is inserted with a replacement pipe 205. The replacement pipe 205 is fixedly connected to the top of the main material pipe 21. One side of the plugging plate 204 away from the replacement pipe 205 is provided with an inner groove 207. The inside of the inner groove 207 is slidably fitted with a slider 208. One end of the slider 208 away from the inner groove 207 is fixedly connected with a second rail 206. The second rail 206 is fixedly connected to the top of the main material pipe 21. In addition, as the material distributing pipe 11 moves downward, the square plate 24 fixedly connected to its outer side will drive the piston rod 25 to move downward, and the piston rod 25 will extend into the compensation pipe 26 from top to bottom, causing the gas accumulated in the compensation pipe 26 and the hollow seat 27 to be compressed and impact the moving rod 28 at the other end of the hollow seat 27. Then the moving rod 28 will extend out of the hollow seat 27 but will not completely extend out of the hollow seat 27, and drive the double-headed rod 29 connected to its other end to move outward together. The sliding rod 201 fixedly connected to the central part of the inner side of the double-headed rod 29 plays a role in supporting and preventing deviation. The fastener 203 connected to the other end of the double-headed rod 29 will pull the plugging plate 204 out of the replacement pipe 205 and away from the replacement pipe 205. Therefore, as the plugging plate 204 extends out of the replacement pipe 205, the replacement pipe 205 will squeeze and move the movable square pipe 14 upward to replace the position of the movable square pipe 14, so that the material distributing pipe 11 will be connected and communicated with the main material pipe 21. The black powder is input from the top end of the material distributing pipe 11 and the top of the feeding pipe 3, so as to achieve the function of multi-channel input and single-channel output of the black powder. In addition, when the hydraulic rod 23 is not started, the material distributing pipe 11 and the main material pipe 21 will not be connected, so as to achieve the function of multi-channel input and multi-channel output.

[0051] As Figure 11 , Figure 12 , Figure 13 and Figure 14 shown, the shunt mechanism 4 includes an end face pipe 41 which is fixedly connected to the outer end faces of the main material pipe 21 and the leakage receiving pipe 209 respectively. A leak prevention net 42 is fixedly connected inside the main material pipe 21. A transfer plate 43 is arranged at the central part of the inner cavity of the end face pipe 41. A bottom plate 44 is fixedly connected to the bottom of the transfer plate 43. A connecting shaft 45 is fixedly connected to the inner side of the bottom plate 44. A support shaft frame 46 is rotatably connected to the outer side of the connecting shaft 45. A universal joint seat 47 is fixedly connected to the bottom of the transfer plate 43. An electric push rod 48 is fixedly connected to the bottom of the universal joint seat 47. Both the support shaft frame 46 and the electric push rod 48 are fixedly connected to the bottom of the inner cavity of the leakage receiving pipe 209. When the weight of the black powder conveyed by the air flow in the main material pipe 21 does not meet the standard, the electric push rod 48 is started, so that the transfer plate 43 connected to its top through the universal joint seat 47 deflects counterclockwise through the connecting shaft 45. Immediately afterwards, part of the air flow will enter the leakage receiving pipe 209 along the surface of the transfer plate 43. The part where the top of the leakage receiving pipe 209 is connected to the top of the main material pipe 21 is unobstructed. Therefore, when the pipeline is placed or has been working for a long time, some black powder will seep from the main material pipe 21 into the leakage receiving pipe 209 and finally enter the leakage receiving pipe 209 along with the air flow, thus playing a role in receiving and recycling the seeping black powder. At the same time, the size of the hole generated by the corrosion of the main material pipe 21 can be judged by the amount of black powder discharged from the leakage receiving pipe 209.

[0052] The anti-clumping mechanism 5 includes a second support 51 which is fixedly connected to the top of the inner cavity of the main material pipe 21. A diverter plate 52 is rotatably connected inside the second support 51. A first magnet 53 is fixedly connected to the outer side of the diverter plate 52. An anti-clumping assembly 54 is arranged beside the first magnet 53. The anti-clumping assembly 54 is symmetrically connected to both ends of the main material pipe 21.

[0053] The anti-agglomeration component 54 includes an inclined end pipe 541, which is fixedly connected to the outside of the main material pipe 21. An inner inclined plate 542 is fixedly connected inside the inclined end pipe 541. A first through rod 543 is inserted into the outside of the inclined end pipe 541. A force-bearing plate 544 is fixedly connected to the outer end of the first through rod 543. A multi-faceted blocking plate 545 is fixedly connected to the end of the first through rod 543 away from the force-bearing plate 544. An inner side of the multi-faceted blocking plate 545 is slidably fitted with a fixing plate 546. When black powder is respectively input from the material distribution pipe 11 and the feeding pipe 3, and at the same time, air flow is injected into the material distribution pipe 11 and the main material pipe 21, the air flow will then impact on the force-bearing plate 544. Immediately afterwards, the first through rod 543 fixedly connected to the other side of the force-bearing plate 544 will penetrate deep into the inclined end pipe 541, and the multi-faceted blocking plate 545 fixedly connected to the other end of the first through rod 543 will move towards the fixing plate 546, causing the stainless steel ice cubes on the inner inclined plate 542 to roll outwards from the position vacated after the movement of the multi-faceted blocking plate 545 and enter the side of the inner cavity of the inclined end pipe 541 away from the inner inclined plate 542. Thus, when there is air flow, the stainless steel ice cubes will be exposed and play a role in cooling the black powder during the conveying process. Appropriately reducing the temperature can reduce the thermal movement of the black powder and lower the probability of collision and combination between particles, so as to avoid the black powder adhering together due to overheating in the pipe and causing agglomeration. The fixing plate 546 is fixedly connected to the inner side of the inclined end pipe 541. A second through rod 547 is fixedly connected inside the multi-faceted blocking plate 545. The second through rod 547 penetrates through the inner side of the inclined end pipe 541 and extends to the outside. A second magnet 548 is fixedly connected to the end of the second through rod 547 away from the multi-faceted blocking plate 545. In addition, as the multi-faceted blocking plate 545 moves towards the fixing plate 546, the second through rod 547 fixedly connected inside the multi-faceted blocking plate 545 will drive the second magnet 548 to move outwards. At this time, the distance between the second magnet 548 and the first magnet 53 will be shortened, resulting in an attractive force between the two. Immediately afterwards, the diversion plate 52 fixedly connected to the other end of the first magnet 53 will deflect downwards through the second support 51. Thus, the black powder flowing out from the material distribution pipe 11 will first be sprinkled on the diversion plate 52 and then enter the main material pipe 21, avoiding directly falling on the main material pipe 21 and causing black powder to fly, increasing the probability of agglomeration. At the same time, the downward deflection of the diversion plate 52 will reduce the degree of black powder flying.

[0054] When the present invention is in use: First, start the hydraulic rod 23, and make its output end contract, so that the material distribution pipe 11 connected to its top end will move downward. At this time, the replacement pipe 205 arranged directly below the movable square pipe 14 will squeeze it. Immediately afterwards, the movable square pipe 14 will move upward along the vertical rail 12 through the slide bar 13. As the movable square pipe 14 moves upward, it will impact the seesaw 103 upward. At this time, the seesaw 103 will deflect counterclockwise through the rotating shaft 102, and the other end of the seesaw 103 will squeeze the flow blocking plate 18 downward, and make the flow blocking plate 18 deflect downward through the first support 17. Finally, the flow blocking plate 18 will block the opening of the transition pipe 15. In addition, as the material distribution pipe 11 moves downward, the square plate 24 fixedly connected to its outer side will drive the piston rod 25 to move downward, and the piston rod 25 will extend into the inside of the compensation pipe 26 from top to bottom, resulting in the gas accumulated in the compensation pipe 26 and the hollow seat 27 being compressed, and impacting the moving rod 28 at the other end of the hollow seat 27. Immediately afterwards, the moving rod 28 will extend out of the hollow seat 27 and drive the double-headed rod 29 connected to its other end to move outward together. The fastener 203 connected to the other end of the double-headed rod 29 will drive the plugging plate 204 to be pulled out of the replacement pipe 205 and away from the replacement pipe 205. Therefore, as the plugging plate 204 extends out of the replacement pipe 205, and the replacement pipe 205 will squeeze and move the movable square pipe 14 upward to replace the position of the movable square pipe 14, so that the material distribution pipe 11 will be connected to the main material pipe 21, and the black powder is input from the top end of the material distribution pipe 11 and the top of the feeding pipe 3.

[0055] When the black powder is input from the material distribution pipe 11 and the feeding pipe 3 respectively, airflows are injected into the material distribution pipe 11 and the main material pipe 21 respectively. At this time, the airflows will impact on the force receiving plate 544. Immediately afterwards, the first through rod 543 fixedly connected to the other side of the force receiving plate 544 will penetrate into the inside of the inclined end pipe 541, and the multi-faceted blocking plate 545 fixedly connected to the other end of the first through rod 543 will move towards the fixed plate 546, resulting in the stainless steel ice cubes on the inner inclined plate 542 rolling out from the position vacated after the multi-faceted blocking plate 545 moves and entering the side of the inner cavity of the inclined end pipe 541 away from the inner inclined plate 542 to perform a cooling treatment on the black powder transported by the airflow. In addition, as the multi-faceted blocking plate 545 moves towards the fixed plate 546, the second through rod 547 fixedly connected to the inside of the multi-faceted blocking plate 545 will drive the second magnet 548 to move outward. At this time, the distance between the second magnet 548 and the first magnet 53 will be shortened, resulting in an attractive force between the two. Immediately afterwards, the flow dividing plate 52 fixedly connected to the other end of the first magnet 53 will deflect downward through the second support 51.

Various changes made by those of ordinary skill in the art starting from the above conceptions without creative efforts fall within the scope of protection of the present invention.
