Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling pretreatment technology, specifically a continuous waste lithium battery shredding device. Background Technology

[0002] In the field of lithium battery recycling, the cells after being unpacked must first undergo crushing. To avoid problems such as incomplete discharge and environmental issues caused during the discharge process, live crushing is usually adopted. Traditional live crushing is generally intermittent, and usually 2-4 valves are arranged above and below the crusher to achieve inert gas sealing throughout the crushing process and ensure safety during the crushing process.

[0003] However, this design results in a discontinuous crushing process, reduced battery processing capacity, and the presence of multiple valves leads to a complex crushing system design, larger overall size, and higher cost.

[0004] Current crushing devices cannot employ an innovative air-knife sealing method. Air-knife sealing devices are installed both above and below the crusher. This device converts the introduced inert gas into a high-pressure, narrow-slit air curtain that covers both sides of the crusher, achieving a sealing effect. Therefore, it cannot achieve high-throughput, live-charge crushing of lithium batteries, better continuous production, or increased lithium battery processing capacity. It also cannot effectively solve the problem of excessively large and complex battery crushing systems, and cannot realize a simple, economical, high-throughput live-charge crushing system. Therefore, we propose a continuous live-charge crushing device for waste lithium batteries. Utility Model Content

[0005] The purpose of this invention is to provide a continuous waste lithium battery shredding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A continuous waste lithium battery crushing device includes a crusher driven by a motor. A feed hopper is fixedly installed at the top of the crusher via a flange. The output end of the crusher is connected to both ends of the crushing roller via bearing components. A discharge bin is fixedly installed at the bottom of the crusher via a flange. The feed hopper is used to feed battery cells, and the discharge bin is used to output the crushed material. The crusher is fixedly installed on a crushing device support via a flange. A crushing chamber is provided inside the crusher, and a screen is fixedly installed inside the crusher, located at the bottom end of the crushing roller.

[0008] The crusher and the outer wall of the discharge hopper are both fixedly installed with air knife bodies via flanges. There are two sets of air knife bodies. Each air knife body includes an air knife body. The air knife body has a first inert gas inlet and a second inert gas inlet at both ends. The first inert gas inlet and the second inert gas inlet are connected by an inert gas supply device to deliver the inert gas body. A narrow slit is opened on the air knife body, and the inert gas body is output through the narrow slit to form an air curtain.

[0009] The discharge hopper is fixedly equipped with a first oxygen analyzer interface, and the feed hopper is fixedly equipped with a second oxygen analyzer interface.

[0010] In a further embodiment, a temperature sensor interface is fixedly installed at the top of the feed hopper via a flange for better temperature monitoring.

[0011] In a further embodiment, the second oxygen analyzer interface is provided with two sets for better monitoring of oxygen concentration.

[0012] In a further embodiment, the crushing device support is provided in multiple sets.

[0013] In a further embodiment, the crusher is equipped with an auxiliary component, which includes a fixed toothed cutter. The fixed toothed cutter is fixedly installed inside the crusher, and there are two sets of fixed toothed cutters located at both ends of the crushing roller, thereby improving the crushing effect.

[0014] In a further embodiment, a hydraulic cylinder is fixedly installed inside the crusher, and a movable plate is fixedly installed at the center of one end of the outer wall of the output end of the hydraulic cylinder. A movable toothed cutter is fixedly installed at the other end of the movable plate. Multiple sets of movable toothed cutters are provided to improve the crushing effect.

[0015] In a further embodiment, the movable toothed cutter and the crushing roller are at the same horizontal height.

[0016] Compared with the prior art, this utility model provides a continuous live-line crushing device for waste lithium batteries, which has the following beneficial effects:

[0017] 1. This continuous waste lithium battery live-line crushing device, in order to better achieve continuous production and improve the processing capacity of lithium batteries during the live-line crushing process, introduces inert gas into the crushing chamber before the feed cells are crushed. This is achieved through two air knife bodies, an upper and a lower one, and inert gas inlets, the air knife body, and a narrow slit, forming two air curtains. When the oxygen analyzer body in the first and second oxygen analyzer interfaces detects that the oxygen content has reached a set threshold, the crusher is started by the motor. The unpacked, live feed cells enter the feed hopper, pass through the air curtain, and enter the crushing chamber. They are crushed under the shearing action of the crushing rollers. After crushing, the material passes through a screen and enters the discharge bin for discharge. The temperature is monitored by a temperature sensor interface. The entire crushing process is continuous and uninterrupted, enabling high-throughput live-line crushing of lithium batteries, better continuous production, and improved lithium battery processing capacity. This effectively solves the problem of excessively large and complex live-line crushing systems, realizing a simple, economical, and high-throughput live-line crushing system.

[0018] 2. In order to improve the crushing effect, this continuous waste lithium battery live crushing device is equipped with auxiliary components. When the feed cells are crushed by the crushing roller, the fixed toothed knife is used to improve the crushing effect. At the same time, the hydraulic cylinder is activated, which causes the moving plate to drive the moving toothed knife to approach the crushing roller, thereby fully crushing the feed cells and thus improving the crushing effect.

[0031] Please see Figures 1-8 This utility model provides a technical solution:

[0032] A continuous waste lithium battery live crushing device includes a crusher 10, which is driven by a motor 101. A feed hopper 2 is fixedly installed at the top of the crusher 10 via a flange. The output end of the crusher 10 is connected to both ends of the crushing roller 4 via bearing components. A discharge bin 5 is fixedly installed at the bottom of the crusher 10 via a flange. The feed hopper 2 is used to feed battery cells 1, and the discharge bin 5 is used to output crushed material 7. The crusher 10 is fixedly installed on the crushing device support 9 via a flange. In addition, the crushing device support 9 is provided with six sets. A first oxygen analyzer interface 8 is fixedly installed on the discharge bin 5. In addition, a temperature sensor interface 11 is fixedly installed at the top of the feed hopper 2 via a flange for better temperature monitoring. A second oxygen analyzer interface 12 is fixedly installed on the feed hopper 2. In addition, two sets of second oxygen analyzer interfaces 12 are provided for better monitoring of oxygen concentration. A crushing chamber 13 is provided inside the crusher 10. A screen 14 is fixedly installed inside the crusher 10 and is located at the bottom of the crushing roller 4.

[0033] In one embodiment of this utility model, air knife bodies 6 are fixedly installed on the outer walls of the crusher 10 and the discharge bin 5 via flanges. There are two sets of air knife bodies 6, each including an air knife body 63. The air knife body 63 has a first inert gas inlet 61 and a second inert gas inlet 62 at both ends. The first inert gas inlet 61 and the second inert gas inlet 62 are connected by an inert gas supply device for conveying inert gas body 64. A narrow slit 65 is opened on the air knife body 63, and the inert gas body 64 is output from the narrow slit 65 to form an air curtain 3.

[0034] In one embodiment of this utility model, an auxiliary component 15 is provided on the crusher 10. The auxiliary component 15 includes fixed toothed cutters 151. The fixed toothed cutters 151 are fixedly installed inside the crusher 10. There are two sets of fixed toothed cutters 151, which are located at both ends of the crushing roller 4, so as to improve the crushing effect. In addition, a hydraulic cylinder 152 is fixedly installed inside the crusher 10. The center of the outer wall of one end of the moving plate 153 is fixedly installed at the output end of the hydraulic cylinder 152. The moving toothed cutters 154 are fixedly installed at the other end of the moving plate 153. There are four sets of moving toothed cutters 154, which improves the crushing effect. In addition, the moving toothed cutters 154 and the crushing roller 4 are at the same horizontal height.

[0035] Working Principle: Before the crushing operation of the feed cell 1 starts, in order to ensure continuous production and improve the lithium battery processing capacity, the device first performs pretreatment through the upper and lower air knife bodies 6. Specifically, the air knife body 6 is connected to the inert gas supply equipment via the first inert gas inlet 61 and the second inert gas inlet 62. The inert gas body 64 is transported to the narrow slit 65 through the air knife body 63, and finally output from the narrow slit 65 to form two air curtains 3 in the crushing chamber 13, thereby creating a suitable crushing environment. When the oxygen analyzer body in the first oxygen analyzer interface 8 and the second oxygen analyzer interface 12 detects that the oxygen content in the crushing chamber 13 has dropped to the set threshold, the signal is transmitted to the controller. The controller, together with the motor 101, drives the crusher 10 to start. At this time, the feed cell 1, which is still charged after unpacking, is put into the feed hopper 2, and then passes through the air curtain 3 into the crushing chamber 13 for crushing. Inside chamber 13, the feed cell 1 is crushed by the shearing action of the crushing roller 4. The crushed material 7 falls under the action of gravity, passes through the screen 14 and enters the discharge bin 5, and is finally discharged from the discharge bin 5. Throughout the process, the temperature sensor interface 11 continuously monitors the temperature of the crushing environment to ensure operational safety and continuous operation. This achieves high-throughput on-charge crushing of lithium batteries. To further improve the crushing effect, when the feed cell 1 is crushed by the crushing roller 4, the fixed toothed blade 151 cooperates with the crushing roller 4 to enhance the shearing and crushing effect. At the same time, the controller controls the hydraulic cylinder 152 to start. The hydraulic cylinder 152 drives the moving plate 153 to move the moving toothed blade 154 closer to the crushing roller 4. Since the moving toothed blade 154 and the crushing roller 4 are at the same horizontal height, the feed cell 1 can be crushed more thoroughly, greatly improving the crushing efficiency and crushing effect.

[0036] All electrical components mentioned in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that controls the air knife body 6, air knife main body 63, first oxygen analyzer interface 8, crusher 10, motor 101, temperature sensor interface 11, second oxygen analyzer interface 12, and hydraulic cylinder 152. All standard parts used in this application can be purchased from the market.

The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
