[0028] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation.

[0029] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0030] The following disclosure provides several different implementations or examples for carrying out this application. To simplify the disclosure of this application, specific examples of components and methods are described below. Of course, these are merely examples and are not intended to limit this application. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] Embodiments of this application provide a material processing method for converting different types of powdered materials into flake materials. This method is performed using predetermined equipment. Figure 9 This illustration shows a schematic diagram of the assembled components of a predetermined device provided in an embodiment of this application, such as... Figure 9 As shown, the predetermined equipment includes a material transfer device 1, a granulation device 2, a stirring device 3, a feeding device 4, and a transfer device 6. The method includes the following steps: S10: Mixing different types of powdered materials using the stirring device 3 to obtain a mixture; S20: Transferring the mixture to the feeding device 4; S30: Using the feeding device 4 to convey the mixture to the material transfer device 1; S40: Using the material transfer device 1 to convert the mixture into a molten state; S50: After the mixture is converted into a molten state, starting the granulation device 2; S60: Using the material transfer device 1 to convey the molten state material to the granulation device 2; S70: Using the granulation device 2 to convert the molten state material into flake material; S80: Using the transfer device 6 to transfer the flake material.

[0032] The material processing method provided in the embodiments of this application obtains a mixture by uniformly mixing different types of raw material powders, melting the mixture and then cooling and granulating it, thereby achieving the fusion of material components, obtaining a stable eutectic salt, and changing the material state from powder to flakes, which facilitates subsequent transportation and utilization.

[0033] In some embodiments, such as Figure 9 As shown, the predetermined equipment can be partially set up in the glove box 7. Since the powdered material is not exposed to the air in the feeding device 4, stirring device 3 and material transfer device 1, setting the granulation device 2 and the transfer device 6 in the glove box can prevent the final produced flaky material from being directly exposed to the air, which is convenient for isolating the material from the operator. Furthermore, the transfer device is set to be connected to the material outlet, which makes it convenient for the operator to collect and transfer the flaky material.

[0034] Figure 10This illustration shows a schematic diagram of the feeding device, stirring device, pressurizing component, and material handling component provided in embodiments of this application. In some embodiments, such as... Figure 10 As shown, the feeding device 4 includes a hopper 41 and a vacuum pump 43. In step S20, the following steps are also included: S21: Vacuum pump 43 is used to evacuate the hopper 41; S22: The mixture is drawn from the stirring device 3 into the evacuated hopper 41 in step S21.

[0035] In some embodiments, in step S21, the feeding device 4 further includes a vacuum pump 44 and a feeding device 45. The vacuum pump 44 is used to connect the vacuum pump 43 and the hopper 41 to achieve vacuuming of the hopper 41. In step S22, the feeding device 45 is used to connect the stirring device 3 and the hopper 41 to achieve the transfer of the mixed materials.

[0036] In some embodiments, the feeding device 4 may also include a weighing element (not shown in the figure), which is configured to weigh the mixture in the hopper 41. In step S30, when the mixture is transferred from the stirring device 3 to the hopper 41, the weight of the mixture is monitored in real time by the weighing element. The transfer is stopped after the weight reaches a predetermined weight. At this time, the hopper 41 is opened to input the predetermined weight of the mixture into the material transfer device 1.

[0037] In some embodiments, a weighing device is provided to control the weight of the mixture entering the material transfer device 1, so that the amount of mixture processed each time is equal, so that the output of the sheet material is equal, while making full use of the space of the material transfer device 1.

[0038] In some embodiments, such as Figure 9 As shown, the material transfer device 1 includes a material handling component 11, a pressurizing component 12, and a transfer component 13. The mixture is conveyed from the hopper 41 into the material handling component 11, where it is transformed into a molten material. In step S60, the following steps are also included: S61: The pressurizing component 12 is activated to provide pressure to the material handling component 11; S62: The molten material in the material handling component 11 is pressurized and conveyed to the transfer component 13; S63: The transfer component 13 conveys the molten material to the granulation device 2.

[0039] Figure 1 This diagram illustrates the assembly of the various components of the material transfer device provided in an embodiment of this application. Figure 1As shown, the material handling component 11 forms a material receiving space for containing powdered material. The material handling component 11 is configured to transform the powdered material into a molten state. Both the pressurizing component 12 and the transfer component 13 are connected to the material handling component 11. The pressurizing component 12 applies pressure to the material receiving space after the powdered material is transformed into a molten state, causing the molten material to move to the transfer component 13. In step S62, both the pressurizing component 12 and the transfer component 13 are configured to maintain the molten material in a molten state, preventing the molten material from solidifying during the transfer process and causing blockage of the transfer component 13. By connecting the pressurizing component 12 and the transfer component 13 to the material handling component 11, when the pressurizing component 12 applies pressure to the material handling component 11, the molten material can flow from the material handling component 11 into the transfer component 13 under pressure. This molten material transfer setup avoids moving the material handling component 11, achieving material transfer solely through gas pressurization, thus simplifying device components and operating steps; it also prevents direct contact between the molten material and air, avoids reactions between the molten material and air, and prevents it from being cooled and solidified by external air, ensuring that the material remains in a molten state throughout the transfer process, making the material transfer process smooth.

[0040] In some embodiments, the material handling assembly 11 is configured to heat the mixture to a molten state, and the heating temperature may be set to 400°C-600°C to allow the mixture to fully melt and react.

[0041] In some embodiments, in step S61, the pressurizing component 12 can be configured to supply argon gas to the material handling component 11, which can both transfer the molten material under pressure and maintain an inert environment within the material handling component 11 to prevent the material from reacting with air and generating impurities.

[0042] In some embodiments, such as Figure 1 As shown, the pressurization assembly 12 includes a pressure supply member 121 and a pressure transmission member 122. The pressure transmission member 122 is configured to communicate with the material handling assembly 11, and the pressure supply member 121 is configured to communicate with the pressure transmission member 122 in gas, so that when the first gas is delivered to the material containing space, the molten material leaves the material containing space.

[0043] Figure 5 This diagram illustrates the assembly of the various components of the granulation apparatus provided in an embodiment of this application. In some embodiments, such as... Figure 5 and Figure 9As shown, the granulation device 2 includes a diversion component 21, a cooling component 22, a scraping component 23, and a storage component 24. In step S50, the following steps are also included: S51: After the mixture is transformed into a molten material, the exhaust gas generated in the material processing component 11 is sucked out by the vacuum pump 43; S52: After the exhaust gas is sucked out, the cooling component 22 is started to allow the cooling medium to enter the cooling component 22.

[0044] In some embodiments, in step S52, activating the cooling assembly 22 before the transfer of the molten material can lower the temperature of the cooling assembly 22 to a temperature that allows the molten material to solidify, so that the molten material can be sufficiently cooled during the initial fall, preventing the material from failing to form sheets.

[0045] In some embodiments, the diversion component 21, the cooling component 22, and the storage component 24 are configured to form a vertical falling transfer mechanism to achieve continuous material transfer through free fall.

[0046] In some embodiments, step S70 further includes the following steps: S71: the transfer component 13 inputs the molten material into the diversion component 21; S72: the diversion component 21 is subjected to pressure from step S61, causing the molten material to fall in droplets under pressure; S73: the droplets fall onto the cooling component 22 in step S52; S74: the cooling component 22 cools the droplets into sheet material; S75: the scraping component 23 scrapes the sheet material off the cooling component 22; S76: the storage component 24 collects the scraped sheet material.

[0047] Figure 2 This illustration shows a schematic diagram of the material transfer component and material handling component cooperating with embodiments of this application. In some embodiments, such as... Figure 2 As shown, the transfer assembly 13 includes a transfer extension 131, a transfer conveyor 132, and a transfer insulation component 133. The transfer extension 131 and the transfer conveyor 132 are integrally formed. The transfer extension 131 is axially extended within the material receiving space and is configured to communicate with the material handling assembly 11 from the same direction as the pressure transmission component 122. The transfer insulation component 133 is configured to continuously insulate the transfer conveyor 132.

[0048] In some embodiments, the transfer extension 131 may be configured to communicate with the pressure transmission member 122 from the upper part of the material handling assembly 11, and the transfer extension 131 may be configured to extend axially to the bottom of the material receiving space so that the molten material can be squeezed from the bottom up into the transfer extension 131 by the gas pressure from the upper part of the receiving space.

[0049] In some embodiments, one end of the transfer conveyor 132 is configured to be perpendicular to and connected to the transfer extension 131, so as to change the flow direction of the molten material to horizontal flow, relieve the pressure in the axial direction, and thereby increase the material flow rate.

[0050] In some embodiments, such as Figure 2 As shown, the extension direction of the end of the transfer conveyor 132 away from the transfer extension 131 is set vertically downward, so that the transfer conveyor 132 and the transfer extension 131 form an inverted U-shaped channel. This allows the molten material to flow out of the transfer conveyor 132 in a falling state, thereby changing the flow direction of the molten material in the vertical direction. This enables the efficient transfer and circulation of the molten material without moving any component of the material transfer device.

[0051] In some embodiments, in step S72, the diversion assembly 21 includes a plurality of diversion elements 213, which are configured in a funnel shape to allow the molten material to flow out in droplets.

[0052] Figure 6 This illustration shows a schematic diagram of the cooling assembly and scraping assembly cooperating with embodiments of this application. In some embodiments, such as... Figure 6 As shown, the scraping assembly 23 includes a scraper 231, a scraping fixing member 232, and a scraping collection member 233. In step S75, the scraper 231 is configured to continuously scrape solid sheet material from the cooling assembly 22. The scraping collection member 233 has a receiving cavity to collect the solid sheet material. Both the scraper 231 and the scraping fixing member 232 are disposed in the receiving cavity. The scraping fixing member 232 is configured to fix the scraper 231 to the scraping collection member 233.

[0053] In some embodiments, the scraping member 231 and the scraping fixing member 232 are respectively fixedly connected to the scraping collection member 233, and the cooling assembly 22 is configured to penetrate and be fixed to the scraping collection member 233, and is partially disposed in the receiving cavity to achieve continuous contact with the scraping member 231.

[0054] In some embodiments, the end of the scraper 231 away from the cooling assembly 22 is fixedly connected to the scraper collection member so that the scraper 231 will not be deformed or displaced by the resistance caused by the condensed material during the scraping process.

[0055] In some embodiments, such as Figure 5 and Figure 6As shown, the cooling assembly 22 includes a water inlet 221, a water outlet 222, and a crystallizer 223. The crystallizer 223 is disposed in the receiving cavity and is configured to receive molten material dripping from the diversion assembly 21. The water inlet 221, the water outlet 222, and the crystallizer 223 are sequentially and coaxially connected, and are configured to allow the cooling medium to enter the crystallizer 223 from the water inlet 221 and leave the crystallizer 223 from the water outlet 222, so as to achieve cooling and crystallization of the molten material. The crystallizer 223 is configured to be able to dynamically contact the scraper 231, thereby generating a relative motion mechanical force to achieve continuous scraping of solid sheet material.

[0056] In some embodiments, in step S74, the crystallizer 223 is configured to rotate within the receiving cavity so that the cooling medium inside moves within it to continuously exchange heat with the dripping molten material, thereby achieving cooling crystallization.

[0057] In some embodiments, in step S76, the storage component 24 can be configured to have a bottom switch. When the scraped flakes accumulate to a predetermined quantity, the operator can manually turn on the bottom switch to package and transfer the material, avoiding the splashing and difficulty in collection caused by the free fall of the flakes, and also giving the operator sufficient time to package and transfer the flakes.

[0058] In some embodiments, during steps S21 and S51, when vacuum pump 43 is used to evacuate hopper 41, the connection between vacuum pump 43 and material handling assembly 11 is cut off; when vacuum pump 43 is used to evacuate material handling assembly 11, the connection between vacuum pump 43 and hopper 41 is cut off.

[0059] In some embodiments, when the vacuum pump 43 evacuates the hopper 41, the powdered material is drawn from the stirring device 3 into the hopper 41 to quickly feed the material without moving the components; when the vacuum pump 43 evacuates the material processing assembly 11, the air inside the material processing assembly 11 is drawn to ensure a stable reaction environment for the material. This enables the reuse of the air extraction component 44 and the vacuum pump 43, simplifying the equipment layout.

[0060] In some embodiments, in step S80, the sheet material from step S76 is packaged, and the packaged sheet material is transferred using the transfer device 6.

[0061] In some embodiments, the operator can package and vacuum the collected sheet material through the operating port of the glove box 7, and place the packaged sheet material on the transfer device 6 for transfer and transportation from the material outlet.

[0062] In some embodiments, in step S10, the stirring device 3 homogenizes and mixes different types of powdered materials to obtain a mixture, while simultaneously removing moisture from the mixture.

[0063] In some embodiments, different types of powdered materials include KCl and LiCl3, and the flake material is a KCl-LiCl3 eutectic salt.

[0064] In some embodiments, the stirring device 3 can be configured to heat the KCl and LiCl3 powders while mixing them. The heating temperature can be set to 120°C-180°C. This temperature setting can remove moisture from the KCl and LiCl3 powders and prevent LiCl3 from hydrolyzing or sublimating due to local overheating.

[0065] In some embodiments, such as Figure 2 As shown, the material handling assembly 11 includes a housing 111, a material container 112, a heating and heat preservation component 113, and a cover 115. The cover 115 is configured to seal the material container 112 and the heating and heat preservation component 113 within the housing 111. The heating and heat preservation component 113 is disposed between the material container 112 and the housing 111. The material container 112 forms a material receiving space. The material receiving space is configured to allow the transfer extension 131 to extend to its bottom so that molten material can be transferred from the material receiving space.

[0066] In some embodiments, the transfer extension 131 extends to the bottom of the material receiving space, which allows the molten material at the bottom to flow into the transfer extension 131 under pressure, thereby transferring the molten material out of the material receiving space as much as possible and reducing residue.

[0067] In some embodiments, such as Figure 2 As shown, the material handling assembly 11 also includes a material purification component 114, which is configured to extend within the material receiving space and to pass through the cover 115. The material purification component 114 is configured to deliver a second gas to the molten material to remove impurities from the molten material.

[0068] In some embodiments, the second gas is configured to remove oxygen ions from the molten material, thereby obtaining a material of higher purity.

[0069] Figure 3 The diagram illustrates the cooperation between the material purification component and the transfer extension component provided in embodiments of this application. In some embodiments, such as... Figure 3As shown, the material purification component 114 includes an axial extension 1141 and a horizontal extension 1142. The axial extension 1141 and the horizontal extension 1142 are integrally formed. The axial extension 1141 is configured to extend out of the material receiving space and pass through the cover 115. The horizontal extension 1142 is configured to extend circumferentially inside the molten material.

[0070] In some embodiments, the axial extension 1141 is configured to extend to the bottom of the material receiving space and is configured to be parallel to the transfer extension 131 to deliver the second gas from top to bottom into the molten material, and the horizontal extension 1142 is configured to extend horizontally at the bottom of the material receiving space so that the output second gas comes into full contact with the molten material from bottom to top to thoroughly purify the material.

[0071] Figure 4 This illustration shows a partial structural diagram of the horizontal extension provided in an embodiment of this application. In some embodiments, such as... Figure 4 As shown, the horizontal extension 1142 is formed with uniformly distributed small holes to increase the contact area between the second gas and the molten material, thereby improving the material purification effect.

[0072] In some embodiments, such as Figure 3 As shown, the transfer extension 131 is configured to be offset from the horizontal extension 1142 in the radial direction, thereby preventing molten material from entering the horizontal extension 1142 and preventing the horizontal extension 1142 from becoming blocked.

[0073] In some embodiments, such as Figure 2 As shown, the transfer insulation component 133 is configured to continuously cover the transfer conveyor 132 in the extending direction of the transfer conveyor 132, so that the material in the transfer process remains in a molten state and prevents solidification in the middle, which would cause blockage of the transfer component 13.

[0074] Figure 7 This illustration shows a schematic diagram of the various components of the cooling assembly provided in an embodiment of this application assembled together. In some embodiments, such as... Figure 7 As shown, the crystallizing component 223 includes a crystallizing portion 2231, a rotating shaft 2232, and a guide portion 2233. The crystallizing portion 2231 forms a cooling cavity that can accommodate the guide portion 2233. The crystallizing portion 2231 is cylindrical and matches the shape of the guide portion 2233. Multiple guide portions 2233 are provided and are uniformly and fixedly distributed along the extension direction of the rotating shaft 2232. The rotating shaft 2232 extends in the cooling cavity and is configured to axially penetrate the inlet component 221 and the outlet component 222.

[0075] In some embodiments, such as Figure 7As shown, the two bottom surfaces of the cylindrical crystallization part 2231 are fixed to the water inlet 221 and the water outlet 222 respectively, so that the water inlet 221 and the water outlet 222 are connected to the cooling chamber, thereby realizing the following cooling process: the cooling medium enters the cooling chamber from the water inlet 221 and exchanges heat with the crystallization part 2231 in the receiving chamber, thereby flowing out of the cooling chamber from the water outlet 222.

[0076] In some embodiments, the flow guide 2233 is configured as a missing annulus, the hollow portion of the annulus is configured to allow the rotating shaft 2232 to pass through and be fixed, and the annulus portion is configured to form a notch on the circumferential outer edge, so as to avoid the formation of a closed space between the flow guides 2233, so as to allow the cooling medium to flow in the cooling chamber.

[0077] In some embodiments, such as Figure 7 As shown, the rotating shaft 2232 is configured to rotate axially, thereby driving multiple guide sections 2233 to rotate axially, which in turn drives the crystallizing section 2231 to rotate axially, so that the crystallizing section 2231 can continuously receive molten material dripping from the diversion component 21, and the material condensed on the crystallizing section 2231 can be continuously scraped off by the scraper 231.

[0078] In some embodiments, such as Figure 6 As shown, the scraping member 231 is configured as a plate-like structure, and the scraping fixing member 232 is configured to contact different surfaces of the plate-like structure to fix the scraping member 231 in a direction perpendicular to the extension direction of the plate-like structure, so as to avoid the scraping member 231 from being displaced or deformed by the relative motion mechanical force. The extension length of the plate-like structure is set to be greater than or equal to the axial length of the crystallized part 2231.

[0079] In some embodiments, the plate structure is configured such that one end can be in close contact with the cooling assembly 22, so that the plate structure can maintain continuous contact with the cooling assembly 22 when the cooling assembly 22 moves relative to it, so as to scrape off the sheet material condensed on the surface of the cooling assembly 22.

[0080] In some embodiments, the scraping fixing member 232 can be configured as multiple fixing rods, both ends of which are fixed to the scraping collection member 233. The multiple fixing rods are arranged to be staggered along different surfaces of the scraping member 231 to clamp and reinforce the plate structure in a direction perpendicular to the extension plane of the plate structure, preventing it from deviating from its original position due to the mechanical force of the condensed material for a long time, and ensuring stable scraping effect.

[0081] In some embodiments, the extension length of the plate-like structure is not less than the axial length of the crystallization portion 2231, so that the extension range of the plate-like structure can cover the axial extension range of the crystallization portion 2231, thereby enabling the scraping off of all condensed material on the crystallization portion 2231 and preventing the omission of condensed material that needs to be scraped off.

[0082] In some embodiments, such as Figure 5 As shown, the scraping collection member 233 has a first opening and a second opening. The first opening and the second opening are coaxial and connected. The second opening is smaller than the first opening. The first opening is located close to the diversion component 21, and the second opening is located close to and connected to the storage component 24.

[0083] In some embodiments, such as Figure 5 As shown, the scraping and collecting member 233 is configured such that its vertical extension range is greater than that of the crystallizing member 223. The part of the scraping and collecting member 233 near the first opening can prevent molten material from splashing everywhere when it drips onto the crystallizing member 223, thus preventing contamination of the operating environment. At the same time, the part of the scraping and collecting member 233 near the second opening can form an inward structure to gather the scraped flake material, so that it falls smoothly into the storage component 24, preventing the material from spilling.

[0084] Figure 8 This illustration shows a partial structural diagram of the transition member and the diverter provided in an embodiment of this application. In some embodiments, such as... Figure 5 and Figure 8 As shown, the diversion component 21 also includes a temporary storage component 211, a transition component 212, and a heat preservation component 214. The transition component 212 is configured to connect the temporary storage component 211 and the diversion component 213 so that the molten material can flow. The temporary storage component 211 is configured to temporarily store the molten material. The transition component 212 is configured to reduce the falling speed of the molten material. Multiple diversion components 213 are configured to divide the molten material into multiple streams. The range of the multiple diversion components 213 dripping the molten material is smaller than the range of the crystallizing component 223. The heat preservation component 214 is configured to keep the molten material in a molten state.

[0085] In some embodiments, the insulation member 214 is configured to continuously cover the temporary storage member 211, the transition member 212 and the diversion member 213 to prevent the molten material in the diversion assembly 21 from cooling and solidifying, causing blockage.

[0086] In some embodiments, the temporary storage member 211 can be configured as a funnel shape with a converging bottom to slow down the flow rate of molten material from the temporary storage member 211 into the transition member 212. The transition member 212 can be configured as a chute communicating with the temporary storage member 211 to further slow down the flow rate of molten material from the transition member 212 into the diverter 213, thereby controlling the overall speed at which molten material drips onto the cooling component 22, ensuring that the cooling component 22 can effectively cool the dripping material, and thus ensuring the granulation effect.

[0087] In some embodiments, such as Figure 5 and Figure 8 As shown, multiple diverting elements 213 are arranged in a distribution direction consistent with the extension direction of the crystallizing part 2231 to ensure that all the material dripping from the diverting element 213 can be received by the crystallizing part 2231 and then solidified into flakes, preventing the waste of molten material.

[0088] In some embodiments, such as Figure 9 As shown, the main body 5 includes a material handling support assembly 51, a feeding support assembly 52, a granulation support assembly 53, and a transfer support assembly 54. The material handling support assembly 51 and the feeding support assembly 52 are integrally formed and form a double-layer space. The material transfer device 1 is set inside the double-layer space and is fixed to the material handling support assembly 51. The feeding device 4 is set outside the double-layer space and is fixed to the feeding support assembly 52. ​​The granulation support assembly 53 and the transfer support assembly 54 are set inside the glove box 7 and are fixedly connected to the glove box 7. The granulation support assembly 53 and the transfer support assembly 54 divide the glove box 7 into four layers of space. The granulation device 2 and the transfer device 6 are set to extend within the four layers of space. The granulation device 2 is fixedly connected to the granulation support assembly 53, and the transfer device 6 is fixedly connected to the transfer support assembly 54.

[0089] In some embodiments, such as Figure 9 As shown, the material handling support assembly 51, the feeding support assembly 52, the granulation support assembly 53, and the transfer support assembly 54 can be configured as a cubic frame. The material handling support assembly 51 and the feeding support assembly 52 are fixedly connected in the vertical direction from top to bottom to form a double-layer space. The granulation support assembly 53 and the transfer support assembly 54 are both fixed inside the glove box 7 and are fixedly connected in the vertical direction from top to bottom to form a four-layer space together with the glove box 7.

[0090] Figure 11 This application shows a schematic cross-sectional view of the body provided in an embodiment of the present application. In some embodiments, such as... Figure 11 As shown, the double-layer space is arranged side by side with the glove box 7. The double-layer space includes a first space 100 and a second space 200, with the second space 200 being higher than the first space 100.

[0091] In some embodiments, the arrangement of the double-layer space alongside the glove box 7 can shorten the transport path of materials from the material transfer device 1 to the granulation device 2 and improve the material flow rate.

[0092] In some embodiments, such as Figure 9 and Figure 11As shown, the material handling component 11 is fixed to the material handling support component 51 and extends within the second space 200. The pressurizing component 12 is located outside the receiving space and is configured to communicate with the material handling component 11. The transfer component 13 extends from the second space 200 into the fourth-layer space.

[0093] In some embodiments, the material handling component 11 is provided to extend into the second space, and the first space 100 serves to raise the height of the material handling component 11, so that the transfer component 13 can connect the material handling component 11 and the granulation device 2, thereby shortening the material flow path.

[0094] In some embodiments, the height of the first space 100 can be set to no more than half the height of the double-layer space, so that the second space 200 occupies a larger height, so as to reserve space for the vertical extension of the transfer component 13, so that the material handling component 11 and the transfer component 13 can extend in the vertical direction and maintain a predetermined distance from the feeding support component 52, so that the feeding device 4 can convey powdered material into the material handling component 11.

[0095] In some embodiments, such as Figure 11 As shown, the four-layer space includes a third space 300, a fourth space 400, a fifth space 500, and a sixth space 600, and are arranged to extend sequentially according to the height of the glove box 7. The third space 300 is the highest and the sixth space 600 is the lowest. The transfer component 13 is arranged to extend into the third space 300.

[0096] In some embodiments, the height of the double-layer space can be set to be higher than the height of the glove box 7 to reduce the height difference between the second space 200 and the third space 300, thereby enabling the molten material to be quickly transferred from the second space 200 to the third space 300 and shortening the extension range of the transfer component 13.

[0097] In some embodiments, such as Figure 9 and Figure 11 As shown, the granulation support assembly 53 includes a diversion support 531, a scraping support 532, and a collection support 533, which are arranged to extend sequentially along the height of the glove box 7. The diversion support 531 and the top of the glove box 7 form a third space 300, the transfer support assembly 54 and the bottom of the glove box 7 form a sixth space 600, the scraping support 532 and the diversion support 531 form a fourth space 400, the scraping support 532 and the transfer support assembly 54 form a fifth space 500, and the collection support 533 is fixed to the scraping support 532.

[0098] In some embodiments, the material falls within the glove box 7, therefore, the glove box 7 needs to be extended to a predetermined height to ensure sufficient space is available for the falling movement of the material.

[0099] Figure 12 This application shows partial detailed views of a granulation apparatus provided in embodiments of the present application. In some embodiments, such as... Figure 5 , Figure 11 and Figure 12 As shown, the diversion component 21 is fixed to the diversion support 531 and extends within the third space 300 and the fourth space 400; the scraping component 23 is fixed to the scraping support 532 and extends within the fourth space 400 and the fifth space 500; the cooling component 22 is configured to pass through the scraping component 23; and the storage component 24 is fixed to the collection support 533 and extends within the fifth space 500.

[0100] In some embodiments, the shunt support 531 is used to support the weight of the shunt assembly 21, such as... Figure 12 As shown, the collecting support 533 is integrally formed with the scraping support 532 to support and restrict the movement of the storage component 24, so that the storage component 24 can fully collect the sheet material scraped off from the cooling component 22 by the scraping component 23.

[0101] In some embodiments, the sixth space 600 is configured such that the transfer device 6 is at a predetermined distance from the bottom of the glove box 7, the predetermined distance being configured to match the height of the operating opening of the glove box 7, so as to facilitate the operation of packaging and transferring sheet materials.

[0102] In some embodiments, such as Figure 10 As shown, the feeding device 4 also includes a dropping component 42, and the vacuum pump 43 is configured to evacuate the hopper 41 via the suction component 44 so that the uniformly mixed powder material in the mixing device 3 can be sucked into the hopper 41 via the feeding component 45, and the uniformly mixed powder material falls into the material processing component 11 via the dropping component 42.

[0103] In some embodiments, the hopper 41 is fixed on the feeding support assembly 52 to ensure stable feeding from the hopper 41; and is arranged to extend vertically outside the double-layer space to avoid occupying the space of the second space 200, and also to avoid the glove box 7 being enlarged to accommodate the arrangement of the hopper 41.

[0104] In some embodiments, the material discharge member 42 is configured to communicate with the hopper 41 and to extend vertically downward into the second space 200 to communicate with the material handling assembly 11 in the second space 200; the vertical extension length of the transfer assembly 13 is less than the extension length of the material discharge member 42, so that the position of the horizontal extension of the transfer assembly 13 to the glove box 7 is within the extension range of the third space.

[0105] In some embodiments, such as Figure 10 As shown, the feeding device 4 also includes a gas transfer unit 46, which is configured to communicate with the material dropping unit 42. The pressure transmission unit 122 is configured to communicate with the gas transfer unit 46, so that the pressure transmission unit 122 is in gas communication with the gas transfer unit 46 and the material dropping unit 42, thereby allowing the pressure supply unit 121 to deliver a first gas to the material handling assembly 11 through the gas communication, so that the molten material leaves the material holding space.

[0106] In some embodiments, such as Figure 10 As shown, the vacuum pump 44 is configured to communicate with the gas transfer unit 46, so that the vacuum pump 43 is in gas communication with the gas transfer unit 46 and the material discharge unit 42, thereby enabling the vacuum pump 43 to evacuate the material handling component 11 through the gas communication to avoid the material reacting with the impurity gas.

[0107] In some embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, the gas transfer component 46 is disposed in the second space 200 and is configured to be in gas communication with the pressure transmission component 122 and the suction component 44 respectively, so that the material discharge component 42 forms a gas passage with the pressure transmission component 122 and the suction component 44 respectively, realizing the reuse of the material discharge component 42 and avoiding the reduction of sealing caused by adding too many openings on the material handling component 11; and the pressure transmission component 122 and the suction component 44 are both configured to extend from different directions outside the double-layer space into the double-layer space, so that they do not interfere with each other in space.

[0108] In some embodiments, the vacuum pump 44 is configured to disconnect from the gas transfer unit 46 when the vacuum pump 43 evacuates the hopper 41, and to disconnect from the hopper 41 when the vacuum pump 43 evacuates the material handling assembly 11.

[0109] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0110] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
