The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] The utility model provides a battery crushing device, which is applied in the field of battery recycling technology. Please refer to Figures 1 to 3 The battery crushing equipment includes a support assembly 1, a crushing assembly 2, a silo 3, at least two baffles and other components that meet the normal operation of the structure, such as a control assembly, which is used to control the operation of the crushing assembly 2 and the baffle. The silo 3 is arranged on the top of the crushing assembly 2, and the crushing assembly 2 is used to crush the batteries dropped from the silo 3. The baffle is arranged inside the silo 3 to divide the silo 3 into at least three feeding chambers, and connects and closes each feeding chamber. The baffle enables the batteries put into the silo 3 to be lowered into the crushing assembly 2 in batches for crushing, thereby improving the efficiency of waste battery garbage treatment. Secondly, an oxygen detection port 6 and a nitrogen nozzle 7 are arranged outside the silo 3. The oxygen content inside the crushing assembly 2 when processing the battery is detected through the oxygen detection port 6. When the oxygen content is too high, the nitrogen-filled device outside will allow the nitrogen to enter the silo 3 through the nitrogen nozzle 7 arranged on the feed silo 3, so that the oxygen content is reduced, thereby avoiding that many flammable substances in the lithium battery electrolyte are burned and exploded when encountering air, causing safety accidents and affecting the ecological environment.

[0037] The structural elements involved above are described in detail below.

[0038] For further information, please refer to Figure 1 and Figure 2 The crushing assembly 2 includes a crushing mechanism and a driving motor 23 for driving the crushing mechanism, and the crushing mechanism includes a crushing shell 21 and a plurality of crushing rollers 22 accommodated in the crushing shell 21. The driving motor 23 drives the crushing rollers 22 to rotate, thereby crushing the battery garbage lowered from the silo 3. It should be noted that in the present embodiment, the plurality of crushing rollers 22 are arranged in an arc shape. This design enables the battery to be well received by the crushing rollers 22 regardless of whether it is lowered along the inner wall of the silo 3 or in the middle. Secondly, the battery lowered to the side of the crushing shell 21 is rotated to the surface of the lower crushing roller 22 through the upper crushing roller 22 and is crushed by the lower crushing roller 22, thereby preventing the battery from getting stuck in the crushing shell 21 and affecting the battery crushing process. It should also be noted that in the present embodiment, the number of crushing rollers 22 is four. Of course, in other embodiments, the number of crushing rollers 22 can be five, six, etc.

[0039] As for the crushing mechanism, it also includes a receiving hopper 24, which is arranged on the bottom surface of the crushing shell 21 and is used to receive the garbage crushed by the crushing roller 22. The opening size of the top surface of the receiving hopper 24 connected to the bottom surface of the crushing shell 21 is larger than the opening size of the bottom surface of the receiving hopper 24, so that the processed battery debris can be exported to the next process.

[0040] In this embodiment, there is a material cavity inside the silo 3, which connects the crushing mechanism with the outside of the silo 3. The material cavity is used to accommodate battery waste and nitrogen thrown in by external equipment. As for the baffles, at least two baffles are movably arranged in the material cavity at intervals along the axial direction of the material cavity to divide the interior of the silo 3 into at least three feed cavities, and connect and close each feed cavity.

[0041] Specifically, in this embodiment, the number of the baffles is two, please refer to Figure 3 Correspondingly, there are three feed chambers. For the convenience of description, the feed chambers are named as the first feed chamber 31, the second feed chamber 32 and the third feed chamber 33 from top to bottom. An oxygen detection port 6 connected to the feed chamber is provided on the outside of the end of the silo 3 close to the crushing mechanism, which means that the oxygen detection port 6 is located on the outer wall of the silo 3 forming the third feed chamber 33. The oxygen detection port 6 at this position is close to the crushing mechanism, so it can detect the oxygen content in the crushing mechanism.

[0042] Furthermore, temperature sensor probes 5 are provided on both sides of the outside of one end of the silo 3 close to the crushing mechanism, that is, two temperature sensor probes 5 are also provided on the outer wall of the silo 3 forming the third feeding chamber 33, which sense the temperature of the battery garbage when it is processed by the crushing mechanism. When the temperature is too high, it is also easy to cause the battery to explode during processing. Therefore, the temperature sensor probes 5 are set to serve as a warning to the operator, or to transmit the temperature data signal to the control element so that the control element can make corresponding adjustments.

[0043] Furthermore, to prevent battery waste from exploding when it is processed in a crushing mechanism, please refer to Figure 1 An explosion vent 331 connected to the crushing mechanism is also provided on the outside of the end of the silo 3 close to the crushing mechanism, that is, an explosion vent 331 connected to the crushing mechanism is also provided on the outer wall of the silo 3 forming the third feeding chamber 33, so as to balance the pressure between the crushing shell 21 and the silo 3 and the outside, prevent the battery waste from exploding under high-pressure treatment, and further improve the safety of battery recycling and treatment.

[0044] As for the nitrogen nozzle 7 provided on the silo 3, please refer to Figure 3 At least two outer walls of the feed chambers are provided with nitrogen nozzles 7 connected to the feed chambers. In the present embodiment, there are two nitrogen nozzles 7, which are respectively provided on the first feed chamber 31 and the second feed chamber 32. The nitrogen nozzles 7 connect the feed chambers with an external device for accommodating nitrogen, and fill the external nitrogen into the feed chambers and then into the crushing mechanism to reduce the oxygen content.

[0045] In this embodiment, please refer to Figure 2 A working bin 4 is extended on one side of the silo 3. The working bin 4 is used to carry the barrier members. Therefore, the number of the barrier members in the above-mentioned embodiment is adopted, and the number of the working bins 4 is also two. The two working bins 4 are respectively set between the outer wall of the first feed chamber 31 and the outer wall of the second feed chamber 32 and between the outer wall of the second feed chamber 32 and the outer wall of the third feed chamber 33.

[0046] In this embodiment, the barrier member includes a hydraulic cylinder 41, which is fixed in the working bin 4 by a first fixing mechanism 43. The hydraulic cylinder 41 is telescopically provided with a piston shaft 42. The end of the piston shaft 42 away from the hydraulic cylinder 41 is fixedly connected with a partition 45 by a second fixing mechanism 44. Part of the partition 45 passes through the side of the bin 3 in the horizontal direction and abuts against the inner wall of the bin 3.

[0047] The first fixing mechanism 43 includes a first fixing plate and a fixing seat, and the fixing seat is arranged on the bottom surface of the working chamber 4; one end of the first fixing plate is fixedly connected to the fixing seat, and the other end is abutted against the top surface of the working chamber 4; the hydraulic cylinder 41 is fixedly connected to the side surface of the first fixing plate, and the piston shaft 42 passes through the first fixing plate and is fixedly connected to the second fixing mechanism 44.

[0048] The second fixing mechanism 44 includes a second fixing plate, and the side surface of the second fixing plate is fixedly connected to the partition 45. This arrangement ensures that the partition 45 can move in parallel and will not deviate during movement due to uneven force on the side of the partition 45.

[0049] In other embodiments, the barrier member can also be driven by the driving motor 23 to rotate in the material cavity to abut against the inner wall of the material cavity to separate the feed cavity.

[0050] The working principle of the baffle is described in detail. The hydraulic cylinder 41 drives the piston rod to move horizontally toward the outer wall of the silo 3, so that the partition 45 passes through the outer wall of the silo 3 and enters the material chamber to abut against the inner wall of the material chamber, thereby closing the material chamber into two feed chambers, so that battery garbage and nitrogen entering the upper feed chamber cannot enter the lower feed chamber. Then, when the items in the feed chamber are to enter the next feed chamber or the crushing mechanism, it is only necessary to control the hydraulic cylinder 41 again to drive the piston to contract, that is, move away from the outer wall of the silo 3, so that the partition 45 moves back to the previous path, ensuring that the partition 45 is located in the working bin 4.

[0051] Further, regarding the description of the bracket assembly 1, the bracket assembly 1 in this embodiment mainly plays the role of bearing and stabilizing the structural element. The bracket assembly 1 includes a plurality of brackets, some of which are connected to form a bearing platform, and the bearing platform is used to bear the crushing assembly 2, and another part of the brackets are connected to form a frame, which supports the working chamber 4 and stabilizes the position of the barrier.

[0052] Finally, the working principle of the battery crushing device is described in detail. First, nitrogen enters the feed chamber through the nitrogen nozzle 7. Before that, all feed chambers are connected. After nitrogen is filled into the third feed chamber 33, the baffle completely closes the second feed chamber 32. Then, the oxygen detection port 6 continuously detects the oxygen content in the third feed chamber 33 and the crushing mechanism through the oxygen detection device during the above process. When the oxygen content is lower than a certain value, for example, lower than 5%, battery waste is started to be put into the silo 3. The partition 4 between the first feed chamber 31 and the second feed chamber 32 5 is moved to the working chamber 4. After a certain period of time, for example, two seconds, the partition 45 is moved back to its original position. After another certain period of time, for example, two seconds, the partition 45 between the second feeding chamber 32 and the third feeding chamber 33 is moved into the working chamber 4. The battery waste enters the crushing shell 21 and is crushed by the crushing roller 22. When all the battery waste enters the crushing shell 21, the partition 45 returns to its original position and closes the third feeding chamber 33. Then, the partition 45 near the first feeding chamber 31 is opened. At this time, a batch of battery waste is processed. It should be noted that the operation of the above-mentioned barrier and the input of nitrogen are controlled by a control element, such as a PLC program control.
