Description

Technical Field

[0001] The invention relates to the technical field of waste battery recycling, and in particular to a waste battery disassembly and recycling device. Background Art

[0002] After the battery is used up, it needs to be recycled because the waste batteries contain heavy metals and electrolyte solutions such as waste acid and waste alkali, which will pollute the environment. In the recycling process, the waste batteries need to be disassembled to recover the useful substances in them. For example, lead-acid batteries need to be disassembled to recover the lead and acid in them.

[0003] At present, there are two main ways to recycle lead blocks in lead-acid batteries: the first is to crush the lead-acid battery first, and then use physical methods to separate the crushed materials to extract useful substances such as lead blocks in the battery, but this method requires additional separation steps to sort the lead blocks, and the operation is more cumbersome; the second method is to first cut the top cover of the lead-acid battery, and then pour out the lead blocks inside for recycling. However, during the use of the battery, the internal battery may bulge, and the lead blocks will expand after bulging. The expanded lead blocks are difficult to pour out directly and are easily stuck inside the battery, resulting in poor processing effects. Summary of the invention

The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0030] A waste battery disassembly and recycling device, such as Figure 1-Figure 6 As shown, it includes a bracket 1, a processing table 2, a feeding track 3, a guide frame 4, a processing frame 5, a cutting mechanism, a feeding mechanism, a slitting mechanism, a pushing mechanism and a discharging mechanism.

The left sides of the two feeding tracks 3 are inclined outward. The lower right part of the processing table 2 is connected to the guide frame 4. The upper part of the left side wall of the guide frame 4 is provided with an inclined surface 41. When the waste battery 100 on the processing table 2 falls into the guide frame 4, The used batteries 100 will first be tilted by the inclined surface 41 on the material guide frame 4, and then flipped over to fall into the material guide frame 4. The bottom of the material guide frame 4 is connected to a processing frame 5. The processing table 2 is provided with a cutting mechanism for cutting the top cover of the used batteries 100, a feeding mechanism for conveying the used batteries 100, and a slitting mechanism for opening a through groove at the bottom of the used batteries 100. The processing frame 5 is provided with a pushing mechanism for pushing the used batteries 100 to move and a unloading mechanism for pushing out the lead plate inside the used batteries 100.

[0031] like Figure 2 As shown, the cutting mechanism includes a side frame 61, a driving motor 62 and a transverse cutting wheel 63. The side frame 61 is installed on the left rear side of the top of the processing table 2, and the driving motor 62 is installed on the front side of the side frame 61. The transverse cutting wheel 63 is connected to the output shaft of the driving motor 62, and the transverse cutting wheel 63 is located above the two feeding tracks 3.

[0032] like Figure 2 and Figure 3 As shown, the feeding mechanism includes an electric belt drive group 71 and a feeding rod 72. The left and right sides of the bottom of the processing table 2 are rotatably connected with mounting shafts 73. Electric belt drive groups 71 are installed between the front and rear sides of the two mounting shafts 73. Multiple feeding rods 72 are evenly spaced and connected between the two electric belt drive groups 71. The upper feeding rod 72 is slightly higher than the feeding track 3.

[0033] like Figure 2 and 3 As shown, the slitting mechanism includes a pressing frame 81, a servo motor 82, a rotating shaft 84 and a cutting saw 83. The pressing frame 81 is connected to the right side of the top of the processing table 2, and the servo motor 82 is installed on the right side of the bottom of the processing table 2. The rotating shaft 84 is connected to the output shaft of the servo motor 82, and the cutting saws 83 are connected to the front and rear sides of the rotating shaft 84. The two cutting saws 83 pass through the processing table 2, and the two cutting saws 83 are located between the two feeding tracks 3.

[0034] like Figure 2 , Figure 4 and Figure 5 As shown, the pushing mechanism includes a driving cylinder 91, a sliding plate 92 and a pushing rack 93. The driving cylinders 91 are installed on the upper parts of the front and rear sides of the processing frame 5. The telescopic rods of the two driving cylinders 91 are connected with sliding plates 92. The sliding plates 92 are slidably connected to the processing frame 5. A pushing rack 93 is connected between the right sides of the two sliding plates 92, and the pushing rack 93 can slide left and right inside the processing frame 5.

[0035] like Figure 4 As shown, the unloading mechanism includes a connecting frame 101, a pushing plate 102, a unloading rack 103 and an elastic member 104. The connecting frame 101 is connected to the left side of the processing frame 5, and the front and rear sides of the right side of the connecting frame 101 are connected to the pushing plate 102. The unloading rack 103 is slidably connected between the connecting frame 101 and the left side of the processing frame 5. An elastic member 104 is connected between the unloading rack 103 and the connecting frame 101, and the elastic member 104 is a connecting spring.

[0036] When the used battery 100 needs to be disassembled and recycled, the present device can be used. When in use, the used battery 100 is first placed on the processing table 2 so that the used battery 100 is located between the two feeding tracks 3, and then the electric belt transmission group 71 is controlled to rotate to drive the feeding rod 72 to move. The feeding rod 72 can push the used battery 100 to move when moving. Before that, the driving motor 62 can be started to drive the transverse cutting wheel 63 to rotate. When the used battery 100 moves to contact the transverse cutting wheel 63, the transverse cutting wheel 63 rotates to cut the top cover of the used battery 100, thereby The top cover of the used battery 100 is cut off, and after being cut off, the used battery 100 continues to move to the bottom of the pressing frame 81, and the used battery 100 is pressed by the pressing frame 81. Previously, the top cover can be taken out manually. When the used battery 100 moves to the bottom of the pressing frame 81, the bottom of the used battery 100 can contact the two cutting saws 83. Previously, the servo motor 82 can be controlled to operate and drive the cutting saw 83 to rotate through the rotating shaft 84, so that the cutting saw 83 can rotate to open two through grooves at the bottom of the used battery 100. The used battery 100 with the through grooves continues to move and falls into the guide frame 4, and is tilted by the inclined surface 41. The used battery 100 is guided obliquely to make the used battery 100 tilted until the used battery 100 vertically passes through the guide frame 4 and falls on the processing frame 5. At this time, the through slot of the used battery 100 faces left, and then the telescopic rod of the driving cylinder 91 can be controlled to extend to drive the sliding plate 92 to move left. When the sliding plate 92 moves to the left, it can drive the pushing rack 93 to move to the left. When the pushing rack 93 moves to the left, it can push the used battery 100 to move to the left. When the used battery 100 moves to the left, the pushing plate 102 can pass through the through slot of the used battery 100 and push the lead inside the used battery 100. The lead blocks are pushed out, and in the process of the used battery 100 moving left, the unloading rack 103 can also be pushed to move leftward, so that the elastic member 104 is compressed. After the lead blocks inside the used battery 100 are pushed out, the telescopic rod of the control driving cylinder 91 is retracted to drive the sliding plate 92 and the pushing rack 93 to reset. At this time, the used battery 100 loses thrust, and the unloading rack 103 is reset under the action of the elastic member 104 to push the used battery 100 out. In this way, the used battery 100 can be disassembled and recycled using the device, and the lead blocks in the used battery 100 can be pushed out during recycling, which makes the operation more convenient.

[0037] like Figure 7As shown, it also includes a material guiding mechanism, which includes a discharge frame 111, a second material guiding frame 112, a pushing cylinder 113 and a pushing plate 114. The discharge frame 111 is connected to the rear side of the pressing frame 81, and the second material guiding frame 112 is connected to the left side of the pressing frame 81. The transverse cutting wheel 63 penetrates into the inner lower part of the second material guiding frame 112, so that the top cover cut off by the transverse cutting wheel 63 will enter the second material guiding frame 112 through the top of the transverse cutting wheel 63. A pushing cylinder 113 is installed in the middle of the front side of the pressing frame 81, and a pushing plate 114 is connected to the telescopic rod of the pushing cylinder 113.

[0038] When the transverse cutting wheel 63 cuts off the top cover of the used battery 100, the cut top cover will enter the second material guide frame 112. As the number of top covers cut off increases, they will all enter the second material guide frame 112, and the top cover entering at the back will push the top cover entering at the front to move to the right until the top cover moves to the rear side of the push plate 114. After the top cover moves to the rear side of the push plate 114, the telescopic rod of the push cylinder 113 is controlled to extend to drive the push plate 114 to move backward, pushing the top cover backward so that the top cover falls on the discharge frame 111 and slides along the discharge frame 111. Before that, the collection frame can be placed under the discharge frame 111. In this way, the top covers of the used batteries 100 can be collected and processed.

[0039] like Figure 8 As shown, it also includes a blocking plate 121 and an elastic member 122. The blocking plate 121 is rotatably connected to the lower left side of the material guide frame 4. Two elastic members 122 are connected between the blocking plate 121 and the material guide frame 4. The elastic member 122 is a torsion spring.

[0040] When the used battery 100 falls on the processing frame 5, such as tilting to the left, the blocking plate 121 can block the upper part of the used battery 100 to prevent the used battery 100 from falling. In this way, the used battery 100 can be blocked to prevent the used battery 100 from falling when it falls on the processing frame 5. When the pushing rack 93 pushes the used battery 100 to move to the left, the blocking plate 121 can be squeezed to rotate, and the second elastic member 122 is deformed until the used battery 100 moves to no longer contact the blocking plate 121. At this time, the blocking plate 121 is reset under the action of the second elastic member 122.

[0041] like Figure 9-11As shown, a blocking mechanism is also included, which includes a baffle plate 131, a sliding frame 132, an elastic member 133 and a protrusion 134. The upper right side of the processing frame 5 is slidably connected with the baffle plate 131, and the baffle plate 131 can slide to the left to block the bottom of the guide frame 4. The front and rear sides of the baffle plate 131 are connected to the sliding frame 132, and the sliding frame 132 is slidably connected to the processing frame 5. An elastic member 133 is connected between the sliding frame 132 and the processing frame 5, and the elastic member 133 is a reset spring. A protrusion 134 is connected to the left side of the sliding frame 132, and the protrusion 134 is located on the right side of the pushing frame 93, so that the pushing frame 93 moving to the right can push the protrusion 134 to move to the right.

[0042] Initially, the pusher rack 93 blocks the protrusion 134, and the elastic member 3 133 is in a stretched state. When the pusher rack 93 pushes the used battery 100 to move, the pusher rack 93 no longer blocks the protrusion 134. At this time, under the action of the elastic member 3 133, the sliding rack 132 and the blocking plate 131 will move to the left, thereby blocking the bottom of the guide frame 4 to prevent new used batteries 100 from falling. In this way, the used batteries 100 can be blocked. When the pusher rack 93 moves to the right to reset, it can contact the protrusion 134 and push the protrusion 134 to move to the right, thereby driving the sliding rack 132 and the blocking plate 121 to reset, and the elastic member 3 133 is stretched again.

[0043] like Fig.12 As shown, it also includes a clamping mechanism, which includes a guide seat 141, an extrusion frame 142 and an elastic member 143. Two guide seats 141 are connected to the front and rear sides of the top of the processing table 2, and an extrusion frame 142 is slidably connected between the two guide seats 141. An elastic member 143 is connected between the extrusion frame 142 and the guide seat 141. The elastic member 143 is a pressure spring, and the left and right sides of the extrusion frame 142 are both inclined.

[0044] When the used batteries 100 are transported, the used batteries 100 can contact the inclined surface 41 of the extrusion rack 142, thereby squeezing the two extrusion racks 142 away from each other, and the two elastic members 143 are compressed. Then, under the action of the elastic members 143, the extrusion rack 142 can limit the movement of the used batteries 100 to prevent the position of the used batteries 100 from being offset.

[0045] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
