Description

Technical Field

[0001] This utility model relates to the field of recycling technology for useful components of waste batteries, and in particular to a sheet material pressing device. Background Technology

[0002] The positive electrode sheet in waste batteries, such as lithium iron phosphate batteries, is a recyclable and useful component. The positive electrode sheet consists of aluminum foil and positive electrode material (black powder). The positive electrode material is bonded to the surface of the aluminum foil and contains lithium. The lithium in the positive electrode material can be recycled to produce lithium carbonate.

[0003] Positive electrode materials are generally recycled by mechanically crushing the positive electrode sheets and then sorting them. The recycled powdered positive electrode materials can be pressed into sheet materials to serve as the cathode of the electrolytic cell, with an inert electrode as the anode, and lithium in the black powder is recovered by electrolytic reduction.

[0004] However, there is currently no specific design for pressing recycled powdered cathode materials into sheet materials, so it is necessary to design a sheet material pressing device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] In view of the above situation, the present invention provides a sheet material pressing device, which aims to provide a sheet material pressing device to facilitate the pressing of recycled powdered positive electrode material into sheet material.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a sheet material pressing device, comprising:

[0009] Fixture;

[0010] The activity features a movable enclosure that is slidably connected to a fixed frame. The movable enclosure and the fixed frame together define a space to form a cavity. The top of the cavity has a feed inlet and the side walls have air inlets.

[0011] The gas delivery pipe is used to deliver a hot gas flow that can soften the viscous material in the positive electrode material to the air inlet.

[0012] In some embodiments of this utility model, the fixing frame is T-shaped; the feed inlet is located in the horizontal part of the fixing frame, and the air inlet is located in the vertical part of the fixing frame.

[0013] In some embodiments of this invention, the temperature of the hot airflow is 45°~55°.

[0014] In some embodiments of this invention, the movable panel is driven by a cylinder.

[0015] In some embodiments of this utility model, an extension rod is provided on one side of the movable panel. The extension rod is located inside the cavity and can block the air inlet.

[0016] In some embodiments of this utility model, there are multiple air inlets.

[0017] In some embodiments of this utility model, a receiving hopper is connected to the top of the horizontal portion of the fixing frame, and the lower outlet of the receiving hopper is connected to the inlet.

[0018] In some embodiments of this utility model, a valve assembly is provided at the feed inlet, and a weighing sensor associated with the valve assembly is provided between the fixing frame and the receiving hopper.

[0019] The embodiments of this utility model have at least the following advantages or beneficial effects:

[0020] After the positive electrode material enters the cavity through the feed port, hot air from the air supply pipe enters the cavity through the air inlet, softening the sticky material in the positive electrode material. This helps to compact the positive electrode material into a sheet material, which is less likely to loosen. The movable partition moves to the left, and the movable partition and the fixed frame work together to compact the positive electrode material into a sheet material with holes. After the movable partition moves to the right and separates from the vertical part of the fixed frame, the sheet material can fall naturally and automatically achieve demolding.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the present invention.

[0026] In the description of the embodiments of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0027] Furthermore, the term "multiple" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] See Figure 1 This embodiment provides a sheet material pressing device, including a fixed frame 61, an air supply pipe 62, and a movable enclosure 63.

[0031] The fixed frame 61 is fixedly installed. The fixed frame 61 is roughly T-shaped. The horizontal part of the fixed frame 61 is provided with a feed inlet 452, and the vertical part of the fixed frame 61 is provided with multiple air inlets 66.

[0032] The air supply pipe 62 is connected to the air inlet 66 and is used to supply hot air at 45°~55° to the air inlet 66.

[0033] The movable enclosure 63 is movably positioned to the left and right. The movable enclosure 63 is slidably connected to the fixed frame 61. The movable enclosure 63 has four inner walls (rear side, right side, front side, and lower side). The movable enclosure 63 and the fixed frame 61 can jointly define a space to form a cavity 64. The feed port 452 is located at the top of the cavity 64 and can communicate with the cavity 64 so that the positive electrode material can enter the cavity 64 through the feed port 452.

[0034] After the positive electrode material enters the cavity 64 through the feed port 452, the hot air in the air supply pipe 62 enters the cavity 64 through the air inlet 66, softening the sticky material in the positive electrode material. This is beneficial for compacting the positive electrode material into a sheet material, which is not easy to loosen. The movable partition plate 63 moves to the left, and the movable partition plate 63 and the fixed frame 61 work together to compact the positive electrode material into a sheet material with holes. After the movable partition plate 63 moves to the right and separates from the vertical part of the fixed frame 61, the sheet material can fall naturally and automatically achieve demolding.

[0035] The driving method of the movable enclosure 63 is not limited; for example, it can be driven by a power source such as a cylinder or a hydraulic cylinder.

[0036] In this embodiment, an extension rod 65 is provided on one side of the movable enclosure 63. The extension rod 65 is located inside the cavity 64 and can block the air inlet 66. By moving the movable enclosure 63 to the left, the extension rod 65 is inserted into the air inlet 66 to block it. The movable enclosure 63 and the fixing frame 61 work together to compact the positive electrode material into a sheet material with holes. This results in a larger contact area between the sheet material, which serves as the cathode of the electrolytic cell, and the electrolyte, leading to higher lithium extraction efficiency.

[0037] In addition, when the gas supply pipe 62 is not directly connected to the air inlet 66 and one end of the air inlet 66 is blocked, before the extension rod 65 is inserted into the air inlet 66 to block the air inlet 66, the hot gas in the gas supply pipe 62 enters the cavity 64 through the air inlet 66, which can also prevent some of the dust-like positive electrode material from overflowing from the air inlet 66.

[0038] In this embodiment, a receiving hopper 451 is connected to the top of the horizontal portion of the fixing frame 61, and the lower outlet of the receiving hopper 451 is connected to the inlet 452. The receiving hopper 451 facilitates the guidance of the positive electrode material into the cavity 64.

[0039] Furthermore, a valve assembly (not shown in the figure) is provided at the feed inlet 452, and a weighing sensor (not shown in the figure) associated with the valve assembly is provided between the fixing frame 61 and the receiving hopper 451. When the weighing sensor detects that the receiving hopper 451 contains a predetermined weight of positive electrode material, the valve assembly opens, allowing the positive electrode material to fall into the cavity 64 and be pressed into a sheet material. This helps to accurately control the size of the sheet material.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. For those skilled in the art, this utility model can have various modifications and variations. Without conflict, the embodiments and features described in this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
