Description

Technical Field

[0001] This utility model relates to a closed crushing device for solid-state batteries with continuous feeding, belonging to the field of solid-state battery recycling technology. Background Technology

[0002] The recyclable components of waste generated after solid-state battery crushing differ from those of traditional lithium-ion batteries. Their key value lies in the positive and negative electrode active materials, solid electrolyte, and current collectors (copper and aluminum foil). Recycling these materials is crucial for environmental protection and resource recycling. During the crushing process of solid-state batteries, to prevent the materials from reacting with air, leading to material denaturation and operational risks, it is typically necessary to maintain an ambient vacuum or inert gas environment. However, adding materials to the crushing equipment requires opening the inner chamber, which not only disrupts the inert gas environment but also interferes with the continuous crushing process, affecting crushing and screening efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a continuously feeding enclosed crushing device for solid-state batteries. This device is used for the continuous feeding and crushing of solid-state battery materials and can provide stable and orderly feeding while maintaining an inert gas environment in the crushing chamber, which helps to improve crushing efficiency.

[0004] To achieve the above objectives, this utility model employs the following technical solution: This utility model provides a continuously feeding, enclosed crushing device for solid-state batteries, including a mounting frame. The mounting frame has a crushing cylinder with a closed inner cavity. A crushing mechanism is installed inside the crushing cylinder. A first suction pipe and a first air supply pipe are connected to the crushing cylinder. A feed inlet is located above the crushing cylinder. At least one side wall of the feed inlet is arc-shaped. A material distribution component is rotatably installed inside the feed inlet. A motor for driving the material distribution component is also installed on the feed inlet. The material distribution component includes multiple partitions arranged in a circumferential array along its axis. Adjacent partitions can form a closed space with the arc-shaped inner wall of the feed inlet. A second suction pipe and a second air supply pipe are connected to the feed inlet at the location of this closed space. Electromagnetic valves for controlling the on / off state of the pipelines are installed on the first suction pipe, the first air supply pipe, the second suction pipe, and the second air supply pipe.

[0005] Specifically, a square tube connected to the inner cavity is fixedly installed on one side above the crushing cylinder, and a discharge pipe is connected to the square tube. The other end of the discharge pipe is connected to a material recycling device.

[0006] Specifically, the first gas supply pipe and / or the second gas supply pipe are provided with heating components for heating the gas.

[0007] Specifically, the crushing mechanism includes multiple crushing blocks laid on the inner wall of the crushing cylinder and a crushing component rotatably disposed inside the crushing cylinder. The crushing component includes two turntables connected to a rotating shaft. Multiple action plates are connected between the two turntables in a circumferential array. The angle of the action plates is tilted to enable the material placed in the crushing cylinder to impact the crushing blocks.

[0008] Specifically, one side of the action plate adopts a knife-edge design, and the thickness at the knife-edge position is no more than 3mm.

[0009] Specifically, the array axis of the multiple action plates is not concentric with the crushing cylinder.

[0010] Specifically, the angle of the action plate is tilted to generate vortex gas inside the crushing cylinder.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention features a material distribution component at the feed inlet of the crushing cylinder. By specially designing the feed inlet, inert gas is introduced and air is extracted through the enclosed space of the feed inlet to replace the gas medium entering the crushing cylinder. This prevents air from being introduced into the crushing process and causing it to react with the crushed material, effectively improving operational safety and ensuring product quality.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0016] This utility model provides a continuously feeding, enclosed crushing device for solid-state batteries, used for continuous feeding and crushing of solid-state battery materials. It can maintain a stable and orderly feeding while keeping the crushing chamber in an inert gas environment, thus improving crushing efficiency. To achieve the device's structural function, it includes a mounting frame 1, on which a crushing cylinder 2 with a closed inner cavity is mounted. The crushing cylinder 2 provides a chamber for crushing materials, and a crushing mechanism is installed inside. This mechanism can adopt the hammer structure of a hammer crusher; other structures are not limited here. To ensure the crushing cylinder... 2. During the crushing process, the chamber can be kept in a vacuum or filled with inert gas. A first extraction pipe 3 and a first supply pipe 4 are connected to the crushing cylinder 2. The first supply pipe 4 supplies inert gas, such as nitrogen, to the chamber of the crushing cylinder 2. The first extraction pipe 3 is used for ventilation within the chamber, extracting air containing water vapor to fill the chamber with inert gas, ensuring that the material avoids contact with air and thus prevents reaction during crushing. To achieve continuous feeding without introducing air, a feed inlet 5 is also provided at the top of the crushing cylinder 2. Figure 4 As shown, at least one side wall of the feed inlet 5 is arc-shaped. A material distribution assembly is rotatably installed inside the feed inlet 5, and a motor 9 is also installed on the feed inlet 5 to drive the rotation of the material distribution assembly. This ensures that the material can enter the crushing chamber provided by the crushing cylinder 2 in an orderly manner. To prevent air from being introduced while the material is being introduced, the material distribution assembly includes multiple partitions 8 arranged in a circumferential array along its axis. Figure 4 As shown, the two adjacent partitions 8 are configured to form a closed space with the arc surface of the inner wall of the feed inlet 5. At this time, a second air extraction pipe 6 and a second air supply pipe 7 are connected to the feed inlet 5 at the position of the closed space. Similar to the first air extraction pipe 3 and the first air supply pipe 4, the air in the closed space is replaced to prevent outside air from entering the chamber where the crushing cylinder 2 is located, ensuring continuous feeding and stability during the crushing process. When the motor 9 is driven, it should be noted that the rotation action is performed in a stepping manner to provide sufficient air exchange time in the closed space. In order to control the air extraction and air supply at reasonable times, solenoid valves for controlling the on and off of the pipelines need to be installed on the first air extraction pipe 3, the first air supply pipe 4, the second air extraction pipe 6, and the second air supply pipe 7 to facilitate automated control.

[0017] This utility model provides a continuously feeding closed-type crushing device for solid-state batteries. In some embodiments, considering that the crushed material cannot directly contact the air, an additional discharge method is provided. Specifically, a square tube 14 connected to the inner cavity is fixedly installed on one side above the crushing cylinder 2, and a discharge pipe 13 is connected to the square tube 14. By connecting the other end of the discharge pipe 13 to a material recovery device, the crushed material can be discharged from the discharge pipe 13 by the suction action of the discharge pipe 13 or by the airflow action in the crushing cylinder 2, avoiding the impact of direct contact with the air caused by opening the hopper to retrieve the material. During operation, inert gas can be introduced into the discharge pipe 13 in advance or a negative pressure state can be maintained to minimize the possibility of material contact with the air.

[0018] This utility model provides a continuously fed solid-state battery enclosed crushing device. In order to keep the gas inside the crushing cylinder 2 sufficiently dry, and to prevent water vapor from forming water droplets inside the crushing cylinder 2 when the equipment is not working, and to facilitate the drying of this moisture so as to prevent moisture from participating in the reaction with the crushed material during the crushing process, a heating component 10 for heating the gas can be provided on the first gas supply pipe 4 and / or the second gas supply pipe 7. The heating component 10 can adopt a structure such as an electric heating wire, and no specific limitations are made here.

[0019] This utility model provides a continuously fed, enclosed crushing device for solid-state batteries. Specifically, it offers a crushing mechanism configuration. The crushing mechanism includes multiple crushing blocks 11 laid on the inner wall of a crushing cylinder 2 and a crushing assembly 12 rotatably disposed inside the crushing cylinder 2. The crushing assembly 12 includes two turntables 1201 connected to a rotating shaft. Figure 6As shown, multiple action plates 1202 are connected in a circular array between two turntables 1201, and the angle of the action plates 1202 is tilted to ensure that the material placed in the crushing cylinder 2 impacts the crushing blocks 11. In this way, the incoming solid-state battery material can be repeatedly impacted and crushed by the crushing blocks 11 in the crushing cylinder 2, achieving impact and compression crushing, and can quickly process the material into a fragmented state. In some preferred embodiments, one side of the action plate 1202 can be designed with a blade. When rotating forward, the impact force of the wall of the action plate 1202 can be used to strike the crushing blocks 11, and when rotating in reverse, the cutting action of the blade can be used to tear the material. Preferably, the thickness at the blade position is no more than 3mm, so that different crushing functions can be achieved in the forward and reverse states. In some other embodiments, impact and shearing effects can also be achieved while rotating in one direction. In order to provide uneven force impact and form more frequent impact in local areas, the array axis of multiple action plates 1202 can be set to be non-concentric with the crushing cylinder 2, such as Figure 6 As shown, when material enters a narrow gap, it is more likely to experience frequent shearing and impact, thereby accelerating the material's fragmentation ability at this location.

[0020] This utility model provides a continuously fed solid-state battery enclosed crushing device. After the material is crushed to a certain extent, in order to avoid it accumulating at the bottom of the crushing cylinder 2 and thus preventing further fine crushing, the angle of the action plate 1202 can be deflected to generate vortex gas inside the crushing cylinder 2. The vortex generated by the rotation action rolls up small particles and makes them collide with the action plate 1202 again, thereby facilitating multiple crushing operations, ensuring sufficient crushing and convenient extraction of crushed material.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
