Description
Technical Field
[0001] This utility model relates to a solid-state battery crushing device, belonging to the field of solid-state battery crushing and recycling technology. Background Technology
[0002] Solid-state batteries typically use highly reactive lithium metal as the negative electrode material. This metal reacts violently with water vapor and oxygen in the air, necessitating a vacuum or inert gas atmosphere during solid-state battery recycling. This prevents the generation of hydrogen gas and potential explosions, while also ensuring the stability of the electrode materials. Currently, there are limited crushing equipment specifically designed for lithium batteries. Existing equipment capable of closed-environment crushing cannot be manually removed after the process (as this would expose the battery materials back to the external environment). Therefore, improving existing crushing equipment to be suitable for solid-state battery crushing is a pressing technical challenge. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a solid-state battery crushing device for crushing solid-state batteries. It can ensure the closed environment of the crushing mechanism while providing a means of discharging crushed materials. It can be adapted to the crushing of solid-state batteries to avoid chemical reactions between materials and external factors.
[0004] To achieve the above objectives, this utility model employs the following technical solution: This utility model provides a solid-state battery crushing device, including a positioning bracket, on which a crushing sleeve is fixedly installed. A rotating cutter head for crushing materials is rotatably arranged inside the crushing sleeve. A motor for driving the rotating cutter head to rotate is also fixedly arranged on one side of the positioning bracket. The crushing space formed by the crushing sleeve is a closed space. An air extraction pipe, an air supply pipe, and a material discharge pipe are respectively connected to the top of the crushing sleeve. Solenoid valves for controlling the on / off of the pipes are installed on the air extraction pipe, the air supply pipe, and the material discharge pipe.
[0005] Specifically, the thickness of the cutting edge of the rotating cutter head is less than 3mm, and the thickness of the blade back is not less than 15mm.
[0006] Specifically, the bottom of the positioning bracket is provided with a guide tube, and a top material block is slidably disposed inside the guide tube. The top material block and the guide tube are sealed together. A lifting component for driving the top material block to rise and fall is also provided on the outside of the guide tube.
[0007] Specifically, the crushing sleeve is in the shape of a hollow cylinder, and the upper surface of the top material block is set as an arc surface that can match the arc surface of the inner wall of the crushing sleeve.
[0008] Specifically, an installation plate is installed on one side of the guide tube opening, the lifting assembly includes a connecting plate, a sliding rod and a threaded rod are installed on the connecting plate, the sliding rod and the threaded rod are parallel to each other, the sliding rod is slidably disposed through the installation plate, and an adjusting nut is rotatably disposed on the installation plate, the threaded rod and the adjusting nut are threadedly connected.
[0009] Specifically, the blades of the rotating cutter head are arranged in an array along the axial direction of the crushing sleeve. A cutter holder is installed on the wall of the crushing sleeve, and multiple decomposition cutters are installed on the cutter holder. The multiple decomposition cutters are arranged in an array on the cutter holder and are staggered with the blades inside the crushing sleeve.
[0010] Specifically, the air supply pipe on the crushing sleeve is tangent to the inner arc surface of the crushing sleeve, and the discharge pipe is connected to the crushing sleeve through a square cover. The square cover is hollow and rectangular in shape, and the air inlet of the square cover is tangent to the inner arc surface of the crushing sleeve.
[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention features a closed design for the existing hammer crusher, equipped with corresponding air extraction pipes, air supply pipes, and discharge pipes. This allows for the extraction of air and the supply of inert gas to the crushing chamber before and after crushing. Simultaneously, after the crushing process is completed, air can be extracted through the discharge pipe while inert gas is being supplied, thereby discharging the powdery material inside to the recycling end. This prevents the crushed material from coming into contact with outside air through the open crushing chamber, which could lead to material deformation and related hazards.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. 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 solid-state battery crushing device for crushing solid-state batteries. It provides a means of discharging crushed material while ensuring a closed environment for the crushing mechanism. It is suitable for crushing solid-state batteries and prevents chemical reactions between the material and external factors. To achieve the device's structural function, it includes a positioning support 1. Its crushing structure can utilize the traditional structure of a hammer crusher, and... Figure 1 and Figure 4As shown, specifically, a crushing sleeve 2 is fixedly installed on the positioning bracket 1, and a rotating cutter head 4 for crushing materials is rotatably arranged inside the crushing sleeve 2. The blades of the rotating cutter head 4 are preferably arranged in a circular array along its axis to enhance the crushing effect and improve the stability of the structure during rotation. A motor 3 for driving the rotating cutter head 4 is also fixedly installed on one side of the positioning bracket 1 to provide power for the crushing action. To prevent air from entering the crushing chamber during the crushing of solid-state batteries, the crushing space formed by the crushing sleeve 2 is configured as a closed space, including the shaft end design of the rotating cutter head 4, which should adopt a corresponding sealing fit design. To prevent residual air in the chamber during the crushing process, an air extraction pipe 5, an air supply pipe 7, and a discharge pipe 6 can be connected and installed above the crushing sleeve 2. Before operation, the air extraction pipe 5 and the air supply pipe 7 can be opened. The air supply pipe 7 supplies inert gases such as argon and nitrogen to the crushing chamber, while the exhaust pipe 5 extracts the gas from the crushing chamber. The two interact to significantly reduce the air content in the crushing chamber. They can be positioned at both ends of the crushing sleeve 2 to increase the distance between the inlet and outlet positions, ensuring that the gas can move sufficiently within the crushing chamber. The discharge pipe 6 is connected to the corresponding waste recycling equipment and is opened after the crushing action is completed. At this time, the air supply pipe 7 and the discharge pipe 6 are opened simultaneously. The air supply pipe 7 provides gas power to blow out the crushed fragments. The discharge pipe 6 can be optionally equipped with a corresponding negative pressure mechanism to adsorb the blown material, thereby quickly realizing the discharge of the crushed material. At this time, the exhaust pipe 5, the air supply pipe 7, and the discharge pipe 6 should all be equipped with solenoid valves to control the opening and closing of the corresponding pipelines so that the program can control the opening and closing of the corresponding pipelines.
[0017] This utility model provides a solid-state battery crushing device. In some embodiments, considering that waste solid-state batteries are initially in a blocky state, directly crushing them with blades can easily damage the blade head and cause slippage. Therefore, to facilitate crushing the blocky object into smaller pieces before further subdivision, the thickness of the blade edge of the rotating blade head 4 can be less than 3mm, and the thickness of the blade back can be not less than 15mm. By configuring the motor 3 to rotate forward and backward, the two working modes of blade back crushing or blade edge crushing can be switched, which helps to improve crushing efficiency and ensure the service life of the rotating blade head 4. In some other embodiments, a corresponding liner can be provided in the inner cavity of the crushing sleeve 2 for impact crushing of solid-state batteries. In this case, the surface of the liner should be provided with a corresponding crushing tooth structure.
[0018] This utility model provides a solid-state battery crushing device. In some embodiments, considering the issue that the volume of the solid-state battery and the device volume may not be effectively matched, the crushing efficiency can be improved by gradually adding material inside the crushing sleeve 2, avoiding the impact of adding too much material at once on the internal space occupied by the device. Specifically, a guide tube 8 can be provided at the bottom of the positioning bracket 1, such as... Figure 2 as well as Figure 5 As shown, a top material block 9 is slidably disposed inside the guide pipe opening 8, and the top material block 9 and the guide pipe opening 8 are configured to seal together. During installation, the battery to be crushed can be placed at the upper end of the top material block 9 beforehand, so that it is placed inside the closed cavity formed by the guide pipe opening 8 and the crushing sleeve 2. The top material block 9 can be gradually lifted during the crushing process, thereby gradually and slowly completing the crushing work, which can effectively increase the one-time crushing capacity. At this time, a lifting component 11 for driving the lifting of the top material block 9 can be provided on the outside of the guide pipe opening 8. The lifting component 11 can be an automated control mechanism or a manual operation, which is not limited here. In some preferred embodiments, an installation plate 10 can be installed on one side of the guide pipe opening 8, and the lifting component 11 can include a connecting plate 1103, such as Figure 2 and Figure 5 As shown, a sliding rod 1101 and a threaded rod 1102 are installed on the connecting plate 1103, with the sliding rod 1101 and the threaded rod 1102 arranged parallel to each other. The sliding rod 1101 is slidably mounted on the mounting plate 10, and an adjusting nut 1104 is rotatably mounted on the mounting plate 10. The threaded rod 1102 and the adjusting nut 1104 are threadedly connected. The top material block 9 is naturally placed or fixed on the connecting plate 1103. When it is necessary to drive the top material block 9 to lift or lower, the adjusting nut 1104 can be rotated directly. In order to fully utilize the working surface of the rotating cutter head 4 and avoid the formation of crushing dead angles in the structural position, the crushing sleeve 2 can be set to be a hollow cylinder, and the upper surface of the top material block 9 can be set to be an arc surface that can match the arc surface of the inner wall of the crushing sleeve 2. In this way, after the top material block 9 is lifted to the corresponding position, it can fit the inner cavity cross section to form a stable crushing space.
[0019] This utility model provides a solid-state battery crushing device. In some embodiments, to facilitate the cutting of solid-state batteries into small pieces before crushing, the blades of the rotating cutter head 4 can be arranged in an array along the axial direction of the crushing sleeve 2, and a cutter holder 13 can be installed on the wall of the crushing sleeve 2. Figure 5As shown, multiple decomposition cutter heads 12 are installed on the cutter holder 13. The multiple decomposition cutter heads 12 are arranged in an array on the cutter holder 13 and are staggered with the blades inside the crushing sleeve 2. With this configuration, a certain cutting gap is formed between the decomposition cutter heads 12 and the crushing blades. After the material is supplied, the solid-state battery can be cut into blocks by using strong shearing force, and then crushed, which facilitates the subsequent crushing work of the equipment.
[0020] In some embodiments of the solid-state battery crushing device provided by this utility model, in order to facilitate the blowing out of the powdery material generated after crushing from the device, the air supply pipe 7 on the crushing sleeve 2 can be configured to be tangent to the inner arc surface of the crushing sleeve 2, and the discharge pipe 6 can be configured to be connected to the crushing sleeve 2 through a square cover. The square cover is configured to be hollow and rectangular in shape. Finally, the air inlet position of the square cover is tangent to the inner arc surface of the crushing sleeve 2. In this way, when air is supplied, the airflow flows around the inner wall section of the crushing sleeve 2 and flows out at the position of the square cover after being guided by the wall. This helps to directly blow away as much powder as possible inside the device, thereby effectively improving the material transfer efficiency.
[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.
