Description

Technical Field

[0001] This utility model relates to a material processing device, and in particular to a positive electrode active material processing device for lithium battery cycle performance, belonging to the field of battery preparation technology. Background Technology

[0002] For example, the processing device for ternary cathode material of lithium battery disclosed in application number 202121482588.0 includes a support plate, a rotating shaft rotatably mounted inside the support plate, a housing rotatably mounted outside the rotating shaft, multiple stirring blades fixedly mounted outside the rotating shaft, a vertical shaft rotatably mounted inside the support plate, sprockets fixedly mounted outside both the vertical shaft and the rotating shaft, the two sprockets being connected by the same chain for transmission, a box fixedly mounted on one side of the bottom of the support plate, a worm and a worm wheel rotatably mounted inside the box, the worm and the worm wheel meshing with each other, a round shaft fixedly mounted on the front side of the worm wheel. The existing technology cannot achieve drying treatment during the processing, and it is not convenient to filter and discharge the gas generated during the drying process.

[0003] Therefore, there is a need for a cathode active material processing device with improved lithium battery cycle performance to address the aforementioned shortcomings. Utility Model Content

[0004] The main purpose of this invention is to provide a device for processing positive electrode active materials to improve the cycle performance of lithium batteries.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A cathode active material processing apparatus for improving the cycle performance of lithium batteries includes a base for placing the apparatus, a mixing assembly mounted on the axis of the base, and the mixing assembly extending into a material processing box.

[0007] The top of the material processing box is supported by a limiting frame, and a lifting drive is installed inside the limiting frame. A connecting rod is installed at the output end of the lifting drive, and a cover is installed at the outer end of the connecting rod. The cover is connected to the material processing box for opening and closing.

[0008] The cover has a connecting cavity at its axial center, and a gas filter is rotatably installed in the connecting cavity. At least one filter sheet is placed inside the gas filter, and the filter sheet is pressed and positioned by a pressure plate.

[0009] Preferably, the connecting cavity and the gas filter are spirally connected, and the gas filter is in communication with the material processing box.

[0010] Preferably, the lifting drive component pushes the connecting rod and the cover to lift and connect.

[0011] Preferably, the mixing assembly includes a rotating rod, a mixing component, a driving component, and a fixed mixing component;

[0012] The base has an opening at the top, and a driving component is installed inside it. A rotating rod is installed at the output end of the driving component. A fixed mixing component is installed on the inner side of the base, intersecting with the mixing component.

[0013] Preferably, an operation panel is installed on the outer side of the base, a heating and drying element is installed around the inside of the base, and a material level sensor is installed on the outer end of the heating and drying element.

[0014] Preferably, the heating and drying components within the base are installed in a circular pattern from high to low.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] This utility model provides a positive electrode active material processing device for improving the cycle performance of lithium batteries.

[0017] 1) After the feeding process is completed, the lifting drive will be activated. Its stable driving force will push the connecting rod synchronously, causing the cover to move precisely towards the opening end of the material processing box, ultimately achieving a tight seal between the two, effectively ensuring the sealing performance and internal environment stability during the processing.

[0018] After the sealing process is completed, the filter sheet is placed stably in the internal cavity of the gas filter element. Then, the pressure plate is precisely placed into the gas filter element. Through the compaction and pressing action of the pressure plate, the filter sheet is kept in a flat and firm assembly state inside the gas filter element, ensuring the effectiveness and stability of the subsequent filtration process.

[0019] The gas filter element is embedded into the connecting cavity at the core of the cover to form a complete exhaust filtration passage. At this time, by rotating the rod and adjusting it, combined with the continuous heating and drying of the heating and drying elements, the internal space of the material processing box can be precisely pressurized, so that the gas inside the box can form a stable discharge force.

[0020] During the gas extraction process, the pressurized gas inside the chamber flows directionally through the gas filter and is effectively filtered by the gradient effect of its multiple layers of filters, thus efficiently intercepting impurities, dust and other pollutants in the gas, ultimately achieving the safe discharge of clean gas and preventing air pollution problems at the source.

[0021] 2) The operator inputs the start command through the equipment's control panel. This command immediately triggers the drive unit to enter the working state. The drive unit quickly outputs stable power and precisely drives the rotating rod to start rotating inside the material processing box at the set speed.

[0022] During the continuous rotation of the rotating rod, it forms an efficient dynamic cross-cooperation with the fixed mixing component pre-installed on the inner wall of the material processing box. When the rotating rod rotates, it not only drives the material in the box to make a circular motion, but also pushes the material to achieve radial tumbling through its own structure. Meanwhile, the fixed mixing component forms a directional obstruction and diversion of the flowing material. Under the synergistic effect of the two, the agglomeration of the material is effectively broken, and a uniform and efficient cross-mixing operation of the material in the box is achieved.

[0023] 3) The material to be processed is first put into the material processing box. In order to realize intelligent and precise control of the drying process, the system integrates a material level sensor on the heating and drying components. This sensor can sense the actual material level height in the processing box in real time and accurately, forming a dynamic material level monitoring signal.

[0024] Based on the material level data fed back by the material level sensor, the system will automatically trigger the start-up logic of the heating and drying components. When the material level reaches the preset processing threshold, the heating and drying components will start precisely and match the heating power and drying time required for the current material level, avoiding the energy waste of "too little material and too much heat" or the problem of incomplete drying of "too much material and too little heat" in the traditional fixed mode.

[0025] It not only ensures the uniformity of material drying and the stability of material quality under different material levels, but also minimizes ineffective energy consumption, significantly improves the energy efficiency ratio and resource utilization of equipment operation, and provides reliable support for the energy-saving and intelligent operation of material processing.

[0036] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0037] Example 1

[0038] like Figure 1 - Figure 4 As shown, the positive electrode active material processing apparatus for lithium battery cycle performance provided in this embodiment includes a base 1 for placing the equipment, and a mixing component is installed on the axis of the base 1. The mixing component penetrates into the material processing box 101.

[0039] The material processing box 101 is supported by a limiting frame 2 at the top. A lifting drive component 201 is installed inside the limiting frame 2. A connecting rod 202 is installed at the output end of the lifting drive component 201. A cover 103 is installed at the outer end of the connecting rod 202. The cover 103 is connected to the material processing box 101 for opening and closing.

[0040] The cover 103 has a connecting cavity 3 on its axis. A gas filter element 301 is rotatably installed in the connecting cavity 3. At least one layer of filter sheet 302 is placed in the gas filter element 301. The filter sheet 302 is pressed and positioned by the pressing sheet 303.

[0041] The connecting cavity 3 and the gas filter 301 are spirally connected, and the gas filter 301 is in communication with the material processing box 101.

[0042] like Figure 1 , Figure 3 and Figure 4As shown, after the feeding process is completed, the lifting drive component 201 will be activated. Its stable driving force will push the connecting rod 202 to move synchronously, thereby driving the cover 103 to move precisely towards the opening end of the material processing box 101, ultimately achieving a tight seal between the two, effectively ensuring the sealing performance and internal environment stability during the processing.

[0043] After the sealing process is completed, the filter 302 is placed stably in the internal cavity of the gas filter 301. Then, the pressure plate 303 is precisely placed into the gas filter 301. Through the pressing action of the pressure plate 303, the filter 302 is kept flat and firmly assembled inside the gas filter 301, ensuring the effectiveness and stability of the subsequent filtration process.

[0044] The gas filter element 301 is embedded into the connecting cavity 3 at the shaft of the cover 103 to form a complete exhaust filtration passage. At this time, by rotating the rotating rod 5 and cooperating with the continuous heating and drying treatment of the heating and drying element 4, the internal space of the material processing box 101 can be precisely pressurized, so that the gas in the box forms a stable discharge force.

[0045] During the gas extraction process, the pressurized gas inside the chamber will flow through the gas filter 301 in a directed manner, and through the gradient filtration effect of its internal multi-layer filter 302, impurities, dust and other pollutants in the gas will be efficiently intercepted, ultimately achieving the safe discharge of clean gas and avoiding air pollution problems at the source.

[0046] Example 2

[0047] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:

[0048] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the mixing assembly further includes 104, a rotating rod 5, a mixing component 501, a driving component 502, and a fixed mixing component 503.

[0049] The base 1 has a top opening 104, a drive component 502 is installed inside the 104, a rotating rod 5 is installed at the output end of the drive component 502, and a fixed mixing component 503 is installed on the inner side of the base 1 in a cross manner with the mixing component 501.

[0050] like Figure 2 and Figure 3 As shown, the operator inputs a start command through the equipment's operation panel 102. This command then triggers the drive unit 502 to enter the working state. The drive unit 502 quickly outputs stable power, precisely driving the rotating rod 5 to start rotating inside the material processing box 101 at a set speed.

[0051] During the continuous rotation of the rotating rod 5, it forms an efficient dynamic cross-cooperation with the fixed mixing component 503 pre-fixed on the inner wall of the material processing box 101. When the rotating rod 5 rotates, it not only drives the material in the box to make a circular motion, but also pushes the material to achieve radial tumbling through its own structure. Meanwhile, the fixed mixing component 503 forms a directional obstruction and diversion of the flowing material. Under the synergistic effect of the two, the agglomeration of the material is effectively broken, and a uniform and efficient cross-mixing operation of the material in the box is achieved.

[0052] Example 3

[0053] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0054] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, an operation panel 102 is further installed on the outer side of the base 1, a heating and drying element 4 is installed around the inside of the base 1, and a material level sensor 401 is installed on the outer end of the heating and drying element 4.

[0055] The heating and drying components 4 inside the base 1 are installed in a ring from high to low;

[0056] like Figure 1 and Figure 2 As shown, the material to be processed is first put into the material processing box 101. In order to realize intelligent and precise control of the drying process, the system integrates a material level sensor 401 on the heating and drying component 4. This sensor can sense the actual material level height in the processing box in real time and accurately, and form a dynamic material level monitoring signal.

[0057] Based on the material level data fed back by the material level sensor 401, the system will automatically trigger the start-up logic of the heating and drying component 4. When the material level reaches the preset processing threshold, the heating and drying component 4 will start precisely and match the heating power and drying time required for the current material level, thus avoiding the energy waste of "too little material and too much heat" or the problem of incomplete drying of "too much material and too little heat" in the traditional fixed mode.

[0058] It not only ensures the uniformity of material drying and the stability of material quality under different material levels, but also minimizes ineffective energy consumption, significantly improves the energy efficiency ratio and resource utilization of equipment operation, and provides reliable support for the energy-saving and intelligent operation of material processing.
