Description

Technical Field

[0001] This utility model relates to the field of lithium battery crushing, and in particular to a short-circuit-proof lithium battery crushing device. Background Technology

[0002] A lithium battery charged crushing device is a device specifically designed for handling and crushing lithium batteries. It safely and efficiently crushes and processes the batteries while they are still charged.

[0003] When crushing lithium batteries while they are charged, nitrogen gas is injected into the casing through pipes on the outer surface and pumps on the support. This nitrogen gas is positioned at the feed hopper, crushing chamber, and discharge pipe to reduce the internal oxygen content, preventing fire or explosion risks caused by short circuits in the lithium batteries during crushing. Then, a motor on one side of the casing is activated, causing the lithium batteries to be crushed by the crushing rollers inside the crushing chamber. Finally, the valve at the discharge pipe is opened to discharge the crushed lithium batteries. However, if the feed hopper is not properly sealed when it reaches the crushing chamber, outside air can flow in, accelerating the increase in oxygen levels in the hopper and crushing chamber. This necessitates a large re-injection of nitrogen before the next crushing cycle, increasing the preparation time for crushing charged lithium batteries and thus affecting the effectiveness of the lithium battery crushing device. Utility Model Content

[0004] The technical problem this invention aims to solve is that when lithium batteries reach the crushing chamber through the feed hopper, the feed hopper is not sealed at the inlet, allowing outside air to flow into the crushing chamber. This causes the oxygen content in the feed hopper and crushing chamber to rise rapidly, requiring a large amount of nitrogen to be injected again before the next crushing of the lithium batteries. This increases the preparation time for crushing lithium batteries while they are charged, thus affecting the performance of the lithium battery crushing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a short-circuit-proof lithium battery live crushing device, including a support, a shell on one side of the support, a crushing chamber inside the shell, a discharge pipe at the lower end of the shell, a feed pipe at the upper end of the shell, a pump on one side of the support, a pipe on one side of the pump, a connection between one side of the pipe and the shell, and a sealing device at the upper end of the feed pipe, which seals the feed pipe with a sealing plate.

[0006] Preferably, the sealing device includes a mounting plate, a first bolt, a fixing plate, an electric telescopic rod, a sealing plate, and a sealing assembly. The mounting plate is disposed on one side of the feed pipe, the first bolt is inserted into one side of the fixing plate to fix it to the mounting plate, the electric telescopic rod is disposed on one side of the fixing plate, and the sealing plate is located at the output end of the electric telescopic rod to seal the feed. The sealing assembly improves the sealing performance at the connection between the sealing plate and the feed pipe.

[0007] Preferably, the sealing assembly includes a second bolt, a connecting plate, and a rubber block. The second bolt is inserted into one side of the connecting plate to be threadedly fixed to the sealing plate. The rubber block is disposed at both ends of the connecting plate, and the size of the rubber block is adapted to the size of the sealing plate.

[0008] Preferably, a control frame is provided on one side of the connecting plate to increase the size of one side of the connecting plate.

[0009] Preferably, the sealing plate is provided with a guide assembly on the side away from the electric telescopic rod. The guide assembly includes a guide plate and a support plate. The guide plate is inclinedly disposed on the side of the sealing plate away from the electric telescopic rod. The two ends of the support plate are connected to the guide plate to support the sealing plate.

[0010] Preferably, a positioning block is provided on one side of the mounting plate to position the fixing plate on the surface of the mounting plate.

[0011] Preferably, the sealing plate is provided with a limiting post on the side near the electric telescopic rod, and one side of the limiting post passes through the fixing plate to slide with the fixing plate.

[0012] Preferably, one side of the fixing plate is provided with several anti-slip blocks to increase the friction on one side of the fixing plate.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] By using a sealing device, the inlet of the feed pipe can be sealed, preventing external air from flowing into the feed pipe and crushing chamber after a batch of charged lithium batteries arrives. This prevents external air from flowing into the crushing chamber after nitrogen is added to the feed hopper, thus accelerating the increase of oxygen content in the hopper and crushing chamber, reducing the amount of nitrogen added, and shortening the preparation time for crushing charged lithium batteries. This improves the performance of the charged lithium battery crushing device. Attached Figure Description

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium.

[0025] Figures 1 to 6The short-circuit-proof lithium battery live crushing device shown includes a support 1, a shell 2 on one side of the support 1, a crushing chamber 3 inside the shell 2, a discharge pipe 4 at the lower end of the shell 2, a feed pipe 5 at the upper end of the shell 2, a pump 6 on one side of the support 1, a pipe 7 on one side of the pump 6, and a connection between the pipe 7 and the shell 2. A sealing device 8 is provided at the upper end of the feed pipe 5, and the sealing device 8 seals the feed pipe 5 through a sealing plate 85. When crushing lithium batteries while they are charged, the lithium batteries are fed into the crushing chamber 3 inside the outer casing 2 through the feed pipe 5. Then, the inlet of the feed pipe 5 is sealed using the sealing device 8. Nitrogen gas is then injected into the outer casing 2 through the pipe 7 on the surface of the outer casing 2 and the pump 6 on the support 1, which is connected to an external nitrogen cylinder. This nitrogen gas is placed in the feed hopper, crushing chamber 3, and discharge pipe 4 to reduce the oxygen content inside and prevent the crushing rollers inside the outer casing 2 from causing a fire or explosion risk due to a short circuit in the lithium batteries during crushing. Then, the motor on one side of the outer casing 2 is started so that the lithium batteries are crushed by the crushing rollers inside the crushing chamber 3. Finally, the valve at the discharge pipe 4 is opened to discharge the crushed lithium batteries.

[0026] Figures 1 to 6 The sealing device 8 shown includes a mounting plate 81, a first bolt 82, a fixing plate 83, an electric telescopic rod 84, a sealing plate 85, and a sealing assembly 86. The mounting plate 81 is disposed on one side of the feed pipe 5, and the first bolt 82 is inserted into one side of the fixing plate 83 to fix it to the mounting plate 81. The electric telescopic rod 84 is disposed on one side of the fixing plate 83, and the sealing plate 85 is located at the output end of the electric telescopic rod 84 to seal the feed. The sealing assembly 86 improves the sealing performance at the connection between the sealing plate 85 and the feed pipe 5.

[0027] Figures 1 to 6 When using the sealing device 8, the fixed plate 83 is moved to contact the mounting plate 81 fixed to the surface of the feed pipe 5. Then, the first bolt 82 is rotated to insert into one side of the fixed plate 83 for threaded fixation with the mounting plate 81. Then, the electric telescopic rod 84 fixed to one side of the fixed plate 83 is activated, causing the sealing plate 85 fixed at the output end of the electric telescopic rod 84 to approach the feed pipe 5 and seal the inlet of the feed pipe 5. At this time, the sealing assembly 86 installed on the edge of the sealing plate 85 lifts the sealing plate. The sealing of the connection between the inlet plate 85 and the feed pipe 5 is achieved by using the sealing device 8 to seal the inlet of the feed pipe 5. This prevents external air from flowing into the feed pipe 5 and the crushing chamber 3 after a batch of charged lithium batteries arrives at the crushing chamber 3. Consequently, after nitrogen is added to the feed hopper, the oxygen content in the crushing chamber 3 will not increase rapidly due to outside air flowing into the crushing chamber 3. This reduces the amount of nitrogen added subsequently, shortens the preparation time for crushing charged lithium batteries, and improves the performance of the charged lithium battery crushing device.

[0028] Figures 1 to 6 The sealing assembly 86 shown includes a second bolt 861, a connecting plate 862, and rubber blocks 863. The second bolt 861 is inserted into one side of the connecting plate 862 and threadedly fixed to the sealing plate 85. The rubber blocks 863 are located at both ends of the connecting plate 862, and the size of the rubber blocks 863 is adapted to the size of the sealing plate 85. By moving the two movable plates to contact the sealing plate 85, the rubber blocks 863 fixed at both ends of the connecting plate 862 are brought into contact with the edge of the sealing plate 85, and then the two rubber blocks 863 form a whole. By rotating the second bolt 861, the second bolt 861 passes through the connecting plate 862 and is threadedly fixed to the sealing plate 85, thus completing the fixation of the positions of the connecting plate 862 and the rubber blocks 863, and improving the sealing performance of the connection between the sealing plate 85 and the feed pipe 5.

[0029] Figures 1 to 6 A control frame 864 is provided on one side of the connecting plate 862 to raise the size of one side of the connecting plate 862. By fixing the control frame 864 to the connecting plate 862, the size of one side of the connecting plate 862 is raised, and then the operator can move the connecting plate 862 more easily through the control frame 864.

[0030] Figures 1 to 6 The sealing plate 85 shown is provided with a guide assembly 87 on the side away from the electric telescopic rod 84. The guide assembly 87 includes a guide plate 871 and a support plate 872. The guide plate 871 is inclinedly disposed on the side of the sealing plate 85 away from the electric telescopic rod 84. The two ends of the support plate 872 are connected to the guide plate 871 to support the sealing plate. By fixing the guide plate 871 inclinedly on the side of the sealing plate 85 away from the electric telescopic rod 84, and by supporting the guide plate 872, when the sealing plate 85 reaches the inside of the feed pipe 5, the guide plate 871 enters the feed pipe 5 first to guide the position of the sealing plate 85, making it easier for the sealing plate 85 to enter the inside of the feed pipe 5.

[0031] Figures 1 to 6 The mounting plate 81 shown has a positioning block 88 on one side to position the fixing plate 83 on the surface of the mounting plate 81. By fixing the positioning block 88 on one side of the mounting plate 81, the fixing plate 83 in contact with the mounting plate 81 can be quickly positioned, which facilitates the subsequent fixing of the fixing plate 83 with the first bolt 82.

[0032] Figures 1 to 6The sealing plate 85 shown has a limiting post 89 on the side near the electric telescopic rod 84. One side of the limiting post 89 passes through the fixing plate 83, allowing it to slide against the fixing plate 83. The limiting post 89 is fixed to the sealing plate 85 on one side and passes through the fixing plate 83 on the other side, slidingly connecting with it. When the sealing plate 85 moves, the limiting post 89 slides on one side of the sealing plate 85, thus limiting the movement trajectory of the sealing plate 85 and making its movement more stable. Several anti-slip blocks 810 are provided on one side of the fixing plate 83 to increase the friction on that side. These anti-slip blocks 810, fixed to one side of the fixing plate 83, increase the friction on that side, making the fixing plate 83 easier to move.

[0033] Working principle: When crushing lithium batteries while they are charged, the lithium batteries are fed into the crushing chamber 3 inside the outer casing 2 through the feed pipe 5. Then, the inlet of the feed pipe 5 is sealed by the sealing device 8. Then, nitrogen gas is injected into the outer casing 2 through the pipe 7 on the surface of the outer casing 2 and the pump 6 on the support 1, which is connected to an external nitrogen cylinder. Nitrogen gas is placed in the feed hopper, crushing chamber 3 and discharge pipe 4 to reduce the oxygen content inside and prevent the crushing rollers inside the outer casing 2 from causing a fire or explosion risk due to a short circuit in the lithium battery. Then, the motor on one side of the outer casing 2 is started so that the lithium battery is crushed by the crushing rollers inside the crushing chamber 3. Finally, the valve at the discharge pipe 4 is opened to discharge the crushed lithium battery. When using the sealing device 8, move the fixed plate 83 so that it contacts the mounting plate 81 fixed to the surface of the feed pipe 5. Then, rotate the first bolt 82 so that it is inserted into one side of the fixed plate 83 to be threadedly fixed to the mounting plate 81. Then, activate the electric telescopic rod 84 fixed to one side of the fixed plate 83 so that the sealing plate 85 fixed at the output end of the electric telescopic rod 84 approaches the feed pipe 5 to seal the inlet of the feed pipe 5. At this time, the sealing assembly 86 installed on the edge of the sealing plate 85 lifts the sealing plate. The sealing of the connection between 85 and the feed pipe 5 is achieved by using a sealing device 8 to seal the inlet of the feed pipe 5. This prevents external air from flowing into the feed pipe 5 and the crushing chamber 3 after a batch of charged lithium batteries arrives at the crushing chamber 3. Consequently, after nitrogen is added to the feed hopper, the oxygen content in the crushing chamber 3 will not increase rapidly due to outside air flowing into the crushing chamber 3, reducing the amount of nitrogen added and shortening the preparation time for crushing charged lithium batteries. This improves the performance of the charged lithium battery crushing device.
