Description
Technical Field
[0001] This utility model relates to the field of can mill technology, specifically a rapid material handling device for can mill cans. Background Technology
[0002] The energy density of liquid batteries is nearing its theoretical limit. Traditional liquid lithium batteries typically have an energy density between 120 Wh / kg and 260 Wh / kg, and even more advanced semi-solid-state batteries struggle to break the 350 Wh / kg bottleneck. Solid-state batteries, however, with advancements in material systems, can achieve higher energy densities, potentially overcoming the energy density bottleneck of liquid batteries. By employing high-specific-capacity positive and negative electrode materials and optimizing solid-state electrolytes, solid-state batteries can achieve higher charge levels for the same mass or volume, thus significantly improving energy density. Currently, solid-state batteries are classified into polymer, sulfide, and oxide electrolytes based on different electrolyte types. Sulfide-based solid electrolytes, with their high ionic conductivity, ease of framework structure formation, and good electrochemical stability, are favored by both academia and industry. Among sulfide solid electrolytes, lithium-silver-germanium mineral-structured electrolytes hold a significant position, particularly Li6PS5X (X = Cl, Br, and I), especially Cl-rich LPSC, which exhibits high ionic conductivity and shows broad application prospects in all-solid-state batteries. However, since LPSC and its precursor materials are extremely sensitive to water and oxygen, and have strict requirements on the particle size of both upstream and downstream, these materials must be finely processed to meet relevant process standards.
[0003] Commonly used equipment for refining LPSC and its precursor materials includes sand mills, air jet mills, planetary ball mills, and jar mills. However, sand mills and air jet mills are expensive and lack economic viability due to their large size, numerous delicate components, and often poor sealing. While planetary ball mills are compact, easy to operate, and convenient for material handling, the frequent jar repositioning significantly reduces efficiency. Jar mills, as ultrafine grinding and mixing equipment for laboratory and small-batch production, are convenient to operate, produce uniform grinding and mixing, are reasonably priced, and can process materials in large quantities, making them a good choice. Although jar mills have significant advantages in terms of economic viability and throughput, the processed materials need to be screened for separation. LPSC and its precursor materials are extremely sensitive to water and oxygen and easily produce highly toxic hydrogen sulfide gas, posing a significant challenge to material screening. Normally, after ball milling in a small rolling mill, the material can be directly placed in a glove box for screening. However, if a large rolling mill is used to process large quantities of material to increase output, the rolling mill cannot fit into the glove box, which undoubtedly significantly reduces production efficiency. Therefore, we have carefully designed a device that allows for rapid material removal from a large rolling mill, while simultaneously achieving efficient material transfer, effectively solving the aforementioned problem. Utility Model Content
[0004] After ball milling in a small roller mill jar, the material can be directly placed in a glove box for screening. However, if a large roller mill is used to process a large volume of material to increase output, the roller mill jar cannot be placed in the glove box. This undoubtedly increases the operational difficulty and significantly reduces production efficiency. This application addresses the shortcomings of the prior art by providing a method and apparatus for rapid material removal from the roller mill jar.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid material handling device for a roller mill, comprising a roller mill body, a vacuum conveying pipe connected to the bottom of the roller mill body, the roller mill body and the vacuum conveying pipe being fixedly connected together by fasteners, a conveying screw for conveying materials being rotatably connected inside the roller mill body, a filter screen for filtering materials being embedded in the bottom port of the roller mill body, a conveying pipe being connected to one side of the bottom of the vacuum conveying pipe, a collection box for collecting filtered materials being provided at the other end of the conveying pipe, and a transmission component for driving the conveying screw to rotate being provided at the bottom of the vacuum conveying pipe.
[0006] As an optimization, the outer side of the conveying screw is shaped like a helical blade, which can be used to transport materials by rotating the helical blade, thus achieving efficient material separation.
[0007] As an optimization, the top diameter of the transmission screw is smaller than the bottom diameter, and it has a conical structure design. The conical design can fully ensure that the grinding balls at the bottom are transmitted to the top to the maximum extent.
[0008] As an optimization, the filter screen plate has several holes with a diameter smaller than that of the grinding balls to ensure that the grinding balls are fully separated.
[0009] As an optimization, the vacuum conveying pipeline is designed to enable rapid powder transfer under extremely low water and oxygen conditions.
[0010] As an optimization, the transmission component is a transmission motor that drives the transmission screw to rotate. One end of the output shaft of the transmission motor is fixedly mounted with a transmission shaft, and the transmission motor is fixedly mounted on the top of the transmission shaft. A positive pressure seal is provided at the bottom of the vacuum conveying pipe and at the top of the transmission motor. By starting the transmission motor, the transmission shaft can be driven to rotate, which in turn drives the transmission screw to rotate and transport materials.
[0011] As an optimization, the positive pressure sealing element is a device that introduces inert gas to ensure that its cavity is in a slightly positive pressure state, thus fully preventing external water and oxygen from entering.
[0012] As an optimization, the fasteners are an upper flange fixedly installed on the bottom side of the roller mill body and a lower flange fixedly installed on the top of the vacuum conveying pipe. Bolts are screwed onto the eccentric parts of the upper flange and the lower flange, and the upper flange and the lower flange can be tightened and fixed in position by tightening the bolts.
[0013] The beneficial effects of this utility model are:
[0014] 1. The rapid material handling device for the mill roller can conveys materials by rotating conical spiral blades, achieving efficient material separation. At the end close to the filter screen plate, the spiral blades continuously convey the grinding balls upwards by rotating, making more space for the materials that have not yet been separated to be conveyed to the filter screen plate under the action of gravity, thereby further promoting the separation of materials.
[0015] 2. The rapid material handling device for the mill's rolling mill uses a conical transmission screw to ensure that the grinding balls at the bottom are conveyed to the top to the maximum extent. The small diameter of the top spiral blades effectively avoids excessive agitation of the unseparated material, making it easier for it to move downwards under gravity and complete the screening process. Therefore, the grinding balls do not need to be removed. After material handling, the material can be directly loaded for re-grinding, which is more efficient than the traditional material handling method.
[0016] 3. The rapid material handling device for the rolling mill can quickly retrieve materials from large rolling mill jars, solving the problem that large rolling mill jars are inconvenient to enter the glove box and are difficult to operate. At the same time, it realizes efficient material transfer and improves production and processing efficiency. Attached Figure Description

[0021] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-3 A rapid material handling device for a roller mill includes a roller mill body 1. The bottom of the roller mill body 1 is connected to a vacuum conveying pipe 2, which is a pipe for rapid powder transfer under extremely low water and oxygen conditions. The roller mill body 1 and the vacuum conveying pipe 2 are fixedly connected together by fasteners. A conveying screw 3 for conveying materials is rotatably connected inside the roller mill body 1. A filter screen plate 4 for filtering materials is embedded in the bottom port of the roller mill body 1. The filter screen plate 4 has several holes with a diameter smaller than the grinding balls to ensure that the balls are fully separated. A conveying pipe 5 is connected to one side of the bottom of the vacuum conveying pipe 2. A collection box 6 for collecting the filtered materials is set at the other end of the conveying pipe 5. A transmission component for driving the conveying screw 3 to rotate is set at the bottom of the vacuum conveying pipe 2.
[0024] Please see Figure 1-3 The outer side of the conveying screw 3 is shaped like a spiral blade, which can be used to transport materials by rotating the spiral blade, thus achieving efficient material separation. At the end close to the screen, the spiral blade continuously transports the grinding balls upward by rotating, making more space for the materials that have not yet been separated to be conveyed to the filter screen plate 4 under the action of gravity, thereby further promoting the separation of materials;
[0025] Please see Figure 1-3 The top diameter of the conveying screw 3 is smaller than the bottom diameter, and it has a conical structure design. The conical design can ensure that the grinding balls at the bottom are conveyed to the top to the maximum extent. The top spiral blades have a small diameter, which can effectively avoid excessive agitation of the unseparated materials, making them easier to move downward under the action of gravity and complete the screening process.
[0026] Please see Figure 1-3 The transmission component is a transmission motor 7 that drives the transmission screw 3 to rotate. One end of the output shaft of the transmission motor 7 is fixedly installed with a transmission shaft 8. The transmission motor 7 is fixedly installed at the top of the transmission shaft 8. A positive pressure seal 9 is set at the bottom of the vacuum conveying pipe 2 and at the top of the transmission motor 7. The positive pressure seal 9 is a device that introduces inert gas to ensure that its cavity is in a slightly positive pressure state, so as to fully prevent external water and oxygen from entering. By starting the transmission motor 7, the transmission shaft 8 can be driven to rotate, which in turn will drive the transmission screw 3 to rotate and transport materials.
[0027] Please see Figure 1-3 The fasteners are an upper flange 10 fixedly installed on the bottom side of the roller mill body 1 and a lower flange 11 fixedly installed on the top of the vacuum conveying pipe 2. Bolts 12 are screwed onto the eccentric parts of the upper flange 10 and the lower flange 11. The upper flange 10 and the lower flange 11 can be fixedly positioned by tightening the bolts 12.
[0028] When in use, the drive motor 7 is started first, which in turn drives the transmission screw 3 to rotate inside the roller mill body 1 through the drive shaft 8. Therefore, the grinding balls are continuously conveyed upward through rotation, making more space for the materials that have not yet been separated to be conveyed to the filter screen plate 4 under the action of gravity, further promoting the separation of materials. The materials separated by the filter screen plate 4 will fall down along the vacuum conveying pipe 2, and then be conveyed to the collection box 6 for collection through the conveying pipe 5.
[0029] In summary, the rapid material handling device for the mill roller can conveys materials by using the rotation of conical spiral blades, achieving efficient material separation. At the end close to the filter screen plate 4, the spiral blades continuously convey the grinding balls upwards by rotation, making more space for the materials that have not yet been separated to be conveyed to the filter screen plate 4 under the action of gravity, thereby further promoting the separation of materials.
[0030] The tapered transmission screw 3 ensures that the grinding balls at the bottom are conveyed to the top to the maximum extent. The small diameter of the top spiral blades effectively avoids excessive agitation of the unseparated material, making it easier for it to move downward under gravity and complete the screening process. Therefore, the grinding balls do not need to be removed. After the material is removed, it can be directly loaded for ball milling again, which is more efficient than the traditional material handling method.
[0031] It can quickly retrieve materials from large rolling mill jars, solving the problem that large rolling mill jars are inconvenient to enter the glove box and are difficult to operate. At the same time, it realizes efficient material transfer and improves production and processing efficiency.
