Description

Technical Field

[0001] The invention relates to the technical field of general crushing, and in particular to a crushing and isolating device for recycling waste lithium batteries. Background Art

[0002] With the development of new energy vehicles, lithium batteries have become one of the most common types of batteries. However, used lithium batteries may be broken, damaged or outdated, which may cause the harmful substances in them to leak and pose potential risks to the environment and health. In order to safely dispose of these used lithium batteries, lithium battery crushing and isolation devices have been developed. Mechanical or physical methods are usually used to crush used lithium batteries to ensure that the harmful substances involved cannot leak out. After crushing, the residues of lithium batteries are usually collected and further processed to minimize the potential impact on the environment and health.

[0003] There are two types of crushing methods at this stage: one is a shredder plus a high-speed hammer crusher. During the crushing process, the hammer crusher quickly beats the crushed material to produce a large number of fine copper and aluminum metal particles, which affects the subsequent separation and recovery, resulting in excessive metal content in the recovered powder, and the pressure expansion of the crushed cavity causes dust and harmful gas leakage, causing environmental pollution. The other is a shredder plus a shredder bipolar crushing. Although it solves the above problems, the shredder is limited in the products it can handle, such as 18650 cylindrical batteries. In addition, the crushed products may have material stacking, and an additional disintegration device is required, which is costly, and the two-stage equipment cannot be effectively sealed, and the risk factor is high.

DETAILED DESCRIPTION

[0036] The following will be combined with the attached Figure 1 To Attachment Fig.12 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, 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 creative work are within the scope of protection of the present invention.

[0037] Embodiment 1: A crushing and isolating device for recycling waste lithium batteries, combined with the attached Figure 1 To Attachment Figure 5, including a frame 101, an oxygen content monitor 102 is fixedly connected to the upper part of the frame 101, and the oxygen content monitor 102 is set as an infrared gas sensor. Wolf tooth type crushing rollers 103 symmetrically distributed along the left and right sides of the frame 101 are rotatably connected in the frame 101, and an air pump 104 is fixedly connected to the lower front side of the frame 101. The oxygen content monitor 102 is electrically connected to the air pump 104 through a control module. The air pump 104 is used to fill nitrogen. An air pipe 105 is connected between the air pump 104 and the frame 101. The air pipe 105 guides the nitrogen to the wolf tooth type crushing roller 103 to achieve low oxygen crushing. The upper front side of the frame 101 is fixed A support frame 106 is connected to stabilize the air pipe 105. The frame 101 is provided with an exhaust valve 107 for limiting the one-way exhaust of gas to avoid excessive gas pressure inside the device. The upper part of the frame 101 is connected with a feed frame 113. The air pipe 105 is connected with the feed frame 113, so that nitrogen is guided into the feed frame 113 to achieve low-oxygen feeding. The upper part of the feed frame 113 is slidably connected with a cover plate 108 in the front-to-back direction. The cover plate 108 is opened forward to feed into the feed frame 113. The lower part of the feed frame 113 is slidably connected with a first sliding plate 109 in the front-to-back direction. The first sliding plate 109 is opened forward. The waste lithium batteries in the feed frame 113 can be dropped to the wolf-tooth crushing roller 103 for crushing. The lower part of the frame 101 is connected to the discharge frame 114. The upper part of the discharge frame 114 is slidably connected to the second sliding plate 110 in the front-to-back direction. The second sliding plate 110 is opened forward so that the crushed lithium battery waste is discharged into the discharge frame 114. The lower part of the discharge frame 114 is slidably connected to the third sliding plate 111 in the front-to-back direction. A collection frame can be placed under the third sliding plate 111. The third sliding plate 111 is opened forward so that the waste lithium batteries in the discharge frame 114 fall into the collection frame. The first sliding plate 110 is opened forward so that the waste lithium batteries in the discharge frame 114 fall into the collection frame. 09 and the third sliding plate 111 are opposite to the opening and closing states of the second sliding plate 110. A rotating plate 112 symmetrically distributed along the left and right sides of the frame 101 is rotatably connected inside the frame 101. The rotating plate 112 is located between the first sliding plate 109 and the wolf-tooth crushing roller 103. A first motor 115 is fixedly connected to the rear side of the frame 101. The infrared gas sensor is electrically connected to the first motor 115 through a control module. The output shaft of the first motor 115 is fixedly connected to the wolf-tooth crushing roller 103 on the right side. A full gear 116 is fixedly connected to the rear side of the wolf-tooth crushing roller 103, and adjacent full gears 116 are meshed with each other.

[0038] Combined with Figure 6, also includes a cylinder 201, the cylinder 201 is fixedly connected to the frame 101, the infrared gas sensor is electrically connected to the cylinder 201 through the control module, the telescopic rod of the cylinder 201 is fixedly connected to the first sliding frame 202, the first sliding frame 202 has a movable groove, the first sliding frame 202 is movably connected to the rotating plate 112 through the movable groove, and is used to adjust the distance between the two rotating plates 112, thereby adjusting the crushing amount of the waste lithium battery, and the front side of the frame 101 is fixedly connected to the guide rail 203, and the first sliding frame 202 slides up and down along the guide rail 203.

[0039] Combined with Figure 7 To Attachment Fig. 9 , further comprising a second motor 301, the second motor 301 is fixedly connected to the frame 101, the infrared gas sensor is electrically connected to the second motor 301 through a control module, the front lower part of the frame 101 is rotatably connected to a first rotating frame 302, the first rotating frame 302 is fixedly connected to the output shaft of the second motor 301, the first sliding frame 202 is rotatably connected to a second sliding frame 303, the lower end of the second sliding frame 303 is engaged with the upper end of the first rotating frame 302, the upper part of the frame 101 is rotatably connected to a second rotating frame 304, the second sliding frame 303 is engaged with the first rotating frame 304, and the second sliding frame 303 is engaged with the first rotating frame 304. The two rotating frames 304 are spline-connected, and the second rotating frame 304 contacts the cover plate 108. When the first sliding frame 202 moves upward, it drives the second sliding frame 303 to separate upward from the first rotating frame 302, so that the second sliding frame 303 cannot rotate, thereby making the second rotating frame 304 unable to rotate, and further making the cover plate 108 unable to be opened. The first sliding plate 109 and the second rotating frame 304, the second sliding plate 110 and the first rotating frame 302, and the third sliding plate 111 and the first rotating frame 302 are all rotatably connected with connecting rods 305.

[0040] First, a collecting frame is placed under the third sliding plate 111, the cover plate 108 is opened, and the waste lithium batteries to be crushed are poured into the feeding frame 113, and then the cover plate 108 is closed. Initially, the rack 101 and the feeding frame 113 are filled with air, and the air contains about 21% oxygen. The air pump 104 is started, and nitrogen is filled into the rack 101 and the feeding frame 113 through the air pipe 105. With the continuous input of nitrogen, the original air will be squeezed by the nitrogen and discharged into the outside air through the exhaust valve 107. Finally, the gas in the rack 101 and the feeding frame 113 is mainly composed of nitrogen, and the oxygen content is reduced. During the process of filling nitrogen, the oxygen content can be monitored in real time by the oxygen content monitor 102. When the oxygen content drops to a safe level (for example, less than 3%), it can be considered that the oxygen has been fully diluted. At this time, the oxygen content monitor 102 sends an electrical signal, the control module receives the electrical signal, and controls the second motor 301 and the first motor 115 to start.

[0041] The output shaft of the second motor 301 drives the first rotating frame 302 to rotate one hundred and eighty degrees, and the first rotating frame 302 drives the third sliding plate 111 to move forward and open through the connecting rod 305, and the first rotating frame 302 drives the second sliding plate 110 to move backward and close through the connecting rod 305. At the same time, the first rotating frame 302 drives the second rotating frame 304 to rotate through the second sliding frame 303, so that the second rotating frame 304 blocks the cover plate 108, and the second rotating frame 304 drives the first sliding plate 109 to move forward and open through the connecting rod 305, so that the waste lithium batteries in the feeding frame 113 enter the frame 101 with low oxygen.

[0042] The output shaft of the first motor 115 drives the full gear 116 to rotate, thereby driving the wolf-tooth crushing roller 103 to run at a low speed, so as to perform low-oxygen crushing treatment on the waste lithium batteries in the frame 101 .

[0043] In summary, the present invention adopts the wolf-tooth crushing roller 103, which mainly relies on low-speed operation to tear and shear and break up to complete the material crushing operation, and can effectively crush and break up the material without adding other crushing and breaking up equipment, and the cost is low.

[0044] The single-pole crushing device of the present invention has good sealing performance and is equipped with a nitrogen filling device and an oxygen content monitoring device, so that the waste lithium batteries are in a low-oxygen environment from feeding to crushing. Nitrogen, as an inert gas, can effectively isolate oxygen in the air, prevent the occurrence of oxidation reaction, maintain the original state of the material, and facilitate subsequent separation and recovery. At the same time, it can prevent the safety hazards caused by the exposure of lithium metal or other flammable substances in the device to the air. Even if there are sparks or high temperatures, it is not easy to cause combustion or explosion accidents, thereby improving the safety of the equipment.

[0045] In addition, the device adopts a sealed structure design to effectively prevent the splashing of dust and metal fragments during the crushing process, which not only protects the safety of the operator but also reduces the impact on the environment.

[0046] After the crushing is completed within a period of time, the control module controls the output shaft of the second motor 301 to drive the first rotating frame 302 to continue to rotate one hundred and eighty degrees, and the first rotating frame 302 drives the third sliding plate 111 to move backward and close through the connecting rod 305, and the first rotating frame 302 drives the second sliding plate 110 to move forward and open through the connecting rod 305, so that the crushed waste batteries fall into the discharge frame 114. At the same time, the first rotating frame 302 drives the second rotating frame 304 to continue to rotate through the second sliding frame 303, so that the second rotating frame 304 no longer blocks the cover plate 108, and the second rotating frame 304 drives the first sliding plate 109 to move backward and close through the connecting rod 305. Then, the cover plate 108 can be opened, and the waste lithium batteries to be crushed can be added to the feed frame 113 again.

[0047] After the feeding is completed within a period of time, the control module controls the output shaft of the second motor 301 to drive the first rotating frame 302 to rotate another one hundred and eighty degrees, so that the first sliding plate 109 and the third sliding plate 111 move forward and open, and the second sliding plate 110 moves backward and closes. At this time, the waste lithium batteries in the feeding frame 113 fall into the frame 101 for crushing, and the waste lithium batteries in the discharging frame 114 are discharged into the collection frame for collection.

[0048] The output shaft of the second motor 301 repeats the above-mentioned intermittent rotation of 180 degrees, so as to achieve the low-oxygen crushing effect of waste batteries in batches.

[0049] In the above-mentioned crushing process, due to the continuous opening and closing of the inlets and outlets of the feed frame 113, the frame 101 and the discharge frame 114, the oxygen content and the nitrogen content may fluctuate. If the oxygen content monitor 102 detects that the oxygen content is higher than the safe level, the control module controls the telescopic rod of the cylinder 201 to contract, thereby driving the first sliding frame 202 to move upward along the guide rail 203, and then driving the two rotating plates 112 to rotate in a direction close to each other, so that the distance between the lower parts of the two rotating plates 112 becomes smaller, thereby reducing the amount of waste lithium batteries falling between the two wolf-tooth crushing rollers 103.

[0050] If the oxygen content monitor 102 detects that the oxygen content is lower than the safe level, the control module controls the telescopic rod of the cylinder 201 to extend, thereby driving the first sliding frame 202 to move downward along the guide rail 203, and then driving the two rotating plates 112 to rotate away from each other, so that the distance between the lower parts of the two rotating plates 112 becomes larger, thereby increasing the amount of waste lithium batteries falling between the two wolf-tooth crushing rollers 103.

[0051] In summary, the present invention can automatically and real-timely regulate the amount of crushing according to the monitored oxygen content, thereby achieving the effect of "reducing the amount of crushing in a non-hypoxic environment and increasing the amount of crushing in a hypoxic environment".

[0052] In the above process of adjusting the crushing amount, when the first sliding frame 202 moves upward, that is, the oxygen content is higher than the safe level, the first sliding frame 202 drives the second sliding frame 303 to move upward along the second rotating frame 304 until it is separated from the first rotating frame 302. In this way, after the crushing is completed within a period of time, the control module controls the output shaft of the second motor 301 to drive the first rotating frame 302 to continue to rotate one hundred and eighty degrees. The first rotating frame 302 cannot drive the second rotating frame 304 to continue to rotate through the second sliding frame 303, resulting in the second rotating frame 304 still blocking the cover plate 108, thereby resulting in the subsequent inability to pull the cover plate 108 forward to feed into the feeding frame 113, and the first rotating frame 302 can still drive the third sliding plate 111 to move backward and close through the connecting rod 305, and the first rotating frame 302 drives the second sliding plate 110 to move forward and open through the connecting rod 305, so that the crushed waste batteries can still fall into the discharging frame 114.

[0053] When the first sliding frame 202 moves downward, that is, the oxygen content is lower than the safe level, the first sliding frame 202 drives the second sliding frame 303 to move downward along the second rotating frame 304 until it engages with the first rotating frame 302 again. In this way, after the crushing is completed, the crushed waste batteries can still fall into the discharge frame 114, and the cover plate 108 can also be pulled forward to feed into the feed frame 113.

[0054] In summary, the present invention controls the engagement relationship between the first rotating frame 302 and the second sliding frame 303 through the first sliding frame 202, and can automatically and in real time adjust whether feeding is possible according to the monitored oxygen content. Without affecting the discharge of the previous batch of lithium batteries, the effect of "feeding cannot be continued in a non-low-oxygen environment, but feeding can continue in a low-oxygen environment" can be achieved for the next batch of lithium batteries.

[0055] Embodiment 2: Based on embodiment 1, Fig.10 and attached Fig.11 , and also includes a synchronous wheel 401, which is fixedly connected to the front end of the rotating plate 112 on the right side, and a guide groove is opened on the front side of the synchronous wheel 401. A moving cylinder 402 is slidably connected in the left and right directions in the support frame 106, and the synchronous wheel 401 is slidably connected to the moving cylinder 402 through the guide groove. An adjusting hole 403 is opened in the middle of the moving cylinder 402, and the air pipe 105 and the moving cylinder 402 are communicated through the adjusting hole 403. The adjusting hole 403 is set to an isosceles triangle. When the moving cylinder 402 moves to the left, the adjusting hole 403 communicating between the moving cylinder 402 and the air pipe 105 is enlarged to increase the amount of nitrogen intake.

[0056] When the two rotating plates 112 rotate toward each other, that is, when the oxygen content is higher than the safety level, the rotating plate 112 on the right side pushes the moving cylinder 402 to move leftward through the synchronous wheel 401, so that the regulating hole 403 connecting the moving cylinder 402 and the air pipe 105 is enlarged, thereby increasing the amount of nitrogen intake.

[0057] When the two rotating plates 112 rotate away from each other, that is, when the oxygen content is lower than the safe level, the rotating plate 112 on the right side pushes the moving cylinder 402 to move rightward through the synchronous wheel 401, so that the regulating hole 403 connecting the moving cylinder 402 and the air pipe 105 is reduced, thereby reducing the amount of nitrogen intake.

[0058] In summary, the present invention controls the size of the adjustment hole 403 connecting the moving cylinder 402 and the air pipe 105 through the rotating plate 112, and can automatically adjust the nitrogen intake in real time according to the monitored oxygen content. In a non-hypoxic environment, the nitrogen intake is increased to accelerate the rapid formation of a hypoxic environment, thereby improving the overall crushing efficiency. In a hypoxic environment, the nitrogen intake is reduced to reduce the waste of nitrogen.

[0059] Embodiment 3: Based on Embodiment 2, Figure 3 and attached Fig.12 , and also includes a plurality of cleaning blocks 501, which are fixedly connected to the bottom of the rotating plate 112. When the two rotating plates 112 are opened normally, the cleaning blocks 501 are close to the wolf-tooth crushing roller 103, so that the lithium battery fragments blocked in the gap between the wolf-tooth crushing rollers 103 can be cleaned in time to avoid affecting the crushing effect of the wolf-tooth crushing rollers 103.
