Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery processing equipment, specifically a nitrogen-protected shredder. Background Technology

[0002] Because lithium batteries are prone to reacting with oxygen during the shredding process, which can cause combustion or explosion, nitrogen-protected shredders are usually used to shred lithium batteries to ensure the safety of the shredding process. A nitrogen-protected shredder is a shredding device that uses nitrogen as a protective gas during the shredding process, which can effectively isolate oxygen.

[0003] When using a nitrogen-protected shredder, the lithium battery to be shredded is usually poured into the machine body beforehand, and then nitrogen is injected into the machine body. When the nitrogen concentration reaches the set value, the blades are driven to rotate, thereby shredding the lithium battery. During the shredding process, nitrogen is continuously replenished to maintain a stable nitrogen concentration and pressure inside the machine body and prevent external air from entering.

[0004] Existing nitrogen-protected shredders can shred lithium batteries using blades, but because the blades are fixed in position, the resulting lithium battery fragments tend to accumulate in certain parts of the machine, especially at the bottom. These accumulated fragments are uneven in size, which ultimately reduces the shredding quality. To address this, we propose a nitrogen-protected shredder. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a nitrogen-protected shredder that can make the lithium battery tumble continuously while the blades are shredding it, so that the lithium battery is shredded more evenly, large fragments are reduced, and the shredding quality of the lithium battery is further improved, which can effectively solve the problems in the background art.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a nitrogen-protected shredder, including a body 1, with a protective door 3 and a sealing door 4 hinged to the lower left and right sides of the upper end of the body 1, an air inlet pipe 5 provided on the upper right side of the body 1, an air inlet valve connected in series in the middle of the air inlet pipe 5, an exhaust pipe 6 on the lower front end of the body 1, an exhaust valve connected in series in the middle of the exhaust pipe 6, an installation box 7 provided in the installation groove opened in the middle of the upper end of the body 1, and also including a shredding mechanism 8;

The fixing rods 84 are all provided on the upper side of the outer arc surface of the first upright 81. The fixing rods 84 are slidably connected to the inner wall of the vertically adjacent limiting grooves.

The lower end of the connecting plate 88 contacts the upper end of the fixing plate 86. Through the cooperation of the fixing plate 86 and the connecting plate 88, the blade 82 can continuously tumble the lithium battery while shredding it. This solves the problem that the shredding effect is affected by some lithium battery deposits at the bottom of the machine body 1. The lithium battery is shredded more evenly, large fragments are reduced, and the shredding quality of the lithium battery is further improved.

[0024] It also includes a microcontroller 2, which is located at the right end of the main body 1. The input terminal of the microcontroller 2 is electrically connected to an external power supply and can regulate the electrical components inside the device.

[0025] The mounting box 7 has a servo motor 11 on the rear right side. The output shaft of the servo motor 11 has a center wheel 9 on the left side. The center wheel 9 has an adjustment rod 10 on the upper left side. The left end of the adjustment rod 10 is located inside the adjustment groove. The input end of the servo motor 11 is electrically connected to the output end of the microcontroller 2. The servo motor 11 starts to run under the control of the microcontroller 2. The output shaft of the servo motor 11 drives the center wheel 9 to rotate. The center wheel 9 will drive the adjustment rod 10 to rotate around the axis of the center wheel 9.

[0026] The upper part of the mounting box 7 is equipped with a drive motor 14. The lower end of the output shaft of the drive motor 14 is fixedly connected to the upper end of the mounting cylinder 83. The input end of the drive motor 14 is electrically connected to the output end of the microcontroller 2. The drive motor 14 starts to run through the control of the microcontroller 2. The output shaft of the drive motor 14 drives the mounting cylinder 83 to rotate. The mounting cylinder 83 drives the first upright 81 to rotate through the fixed rod 84. The first upright 81 drives the blade 82 to rotate.

[0027] The mounting box 7 has a second upright 12 on its front and rear sides. The second upright 12 is slidably connected to the clearance groove corresponding to the lower end of the fixing plate 86. A spring 13 is provided between the lower end of the fixing plate 86 and the bottom wall of the mounting box 7. The spring 13 is sleeved on the outside of the lower side of the second upright 12. The thrust generated by the extension of the spring 13 will drive the connecting ring 85 to move upward and reset through the fixing plate 86.

[0028] Among them: a nitrogen concentration detector 15 is installed on the right side of the upper end of the body 1. The nitrogen concentration detector 15 is bidirectionally electrically connected to the microcontroller 2. The nitrogen concentration detector 15 detects the nitrogen concentration inside the body 1 in real time and transmits the detected data to the microcontroller 2.

[0029] The working principle of the nitrogen-protected shredder provided by this utility model is as follows: During the use of the nitrogen-protected shredder, first open the protective door 3, then pour the lithium battery to be shredded into the interior of the machine body 1. After the lithium battery is added, close the protective door 3 again, and then connect the air inlet pipe 5 and the exhaust pipe 6 to the external pipeline. After the connection is completed, open the air inlet valve and the exhaust valve. Nitrogen enters the interior of the machine body 1 through the air inlet pipe 5, while the air inside the machine body 1 is discharged through the exhaust pipe 6. The nitrogen gradually replaces the air in the machine body 1, forming a nitrogen protective atmosphere. The nitrogen concentration detector 15 detects the nitrogen concentration inside the machine body 1 in real time and transmits the detected data to the microcontroller 2. When the nitrogen concentration inside the machine body 1 reaches the set value, the microcontroller 2 controls the drive motor 14 to start running. The output shaft of the drive motor 14 drives the mounting cylinder 83 to rotate. The mounting cylinder 83 drives the first upright 81 to rotate via the fixed rod 84. The first upright 81 drives the blade 82 to rotate, thereby tearing the lithium battery inside the machine body 1 into smaller fragments. During the rotation of the blade 82, the microcontroller 2 controls the servo motor 11 to start running. The output shaft of the servo motor 11 drives the center wheel 9 to rotate. The center wheel 9 drives the adjusting rod 10 to rotate around the axis of the center wheel 9. Since the axis of the adjusting rod 10 does not coincide with the axis of the center wheel 9, the adjusting rod 10 will generate [something] during its circular motion. Lateral and vertical displacements occur, causing the adjusting rod 10 to slide and rotate relative to each other within the adjusting groove. This causes the adjusting rod 10 to drive the connecting plate 88 to rotate around the connecting rod 87. When the connecting plate 88 rotates downwards, it drives the connecting ring 85 downwards via the fixing plate 86, causing the spring 13 to contract. The connecting ring 85 then drives the first upright 81 downwards via the fixing rod 84, which in turn drives the blade 82 downwards. When the connecting plate 88 rotates upwards, the thrust generated by the extension of the spring 13 drives the connecting ring 85 upwards via the fixing plate 86. The connecting ring 85 then drives the first upright 81 upwards via the fixing rod 84. 1. This causes the blade 82 to move upward, thereby causing the lithium battery to tumble continuously while being shredded. During the shredding process, nitrogen is continuously replenished to maintain a stable nitrogen concentration and pressure inside the machine and prevent external air from entering. After the lithium battery is shredded, the sealing door 4 is opened first, and then the shredded lithium battery fragments are discharged. After the discharge is completed, the sealing door 4 is closed again, and then external air is injected into the interior of the machine body 1 through the air inlet pipe 5. The nitrogen inside the machine body 1 is discharged through the exhaust pipe 6, thereby expelling the nitrogen inside the machine body 1. During the nitrogen discharge process, the nitrogen concentration detector 15 monitors the nitrogen concentration inside the machine body 1 in real time to ensure that the nitrogen is completely discharged.

[0030] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM8S207S8T6C, the servo motor 11 and the drive motor 14 can be 5IK200A-AF, and the nitrogen concentration detector 15 can be MOT500-N2. The microcontroller 2 controls the operation of the servo motor 11, the drive motor 14 and the nitrogen concentration detector 15 using methods commonly used in the prior art.
