The cooling assembly 22 is arranged to penetrate and be fixed to the scraping collection piece 233 and partially arranged in the containing cavity to realize continuous contact with the scraping piece 231.

[0037] In some embodiments, one end of the scraping piece 231 away from the cooling assembly 22 is fixedly connected with the scraping collection piece, so that the scraping piece 231 will not be deformed or displaced by the resistance of the condensed material during the scraping process.

[0038] In some embodiments, as shown in Figure 5 and Figure 6 The cooling assembly 22 includes a water inlet piece 221, a water outlet piece 222 and a crystallization piece 223. The crystallization piece 223 is arranged in the containing cavity and arranged to receive the material in molten state dropped from the shunting assembly 21. The water inlet piece 221, the water outlet piece 222 and the crystallization piece 223 are coaxially arranged in sequence and arranged to allow the cooling medium to enter the crystallization piece 223 from the water inlet piece 221 and exit the crystallization piece 223 from the water outlet piece 222, so as to realize cooling and crystallization of the material in molten state. The crystallization piece 223 is arranged to dynamically contact the scraping piece 231, so as to generate relative motion mechanical force, thereby realizing continuous scraping treatment of the solid sheet material.

[0039] In some embodiments, the crystallization member 223 is arranged to be capable of rotational movement in the accommodating cavity, so that the cooling medium inside is moved to continuously exchange heat with the molten material dropping from the dripping assembly 21, to achieve crystallization.

[0040] Figure 7 A schematic diagram showing the assembly of the components of the cooling assembly provided by the embodiments of the present application is shown in some embodiments, as shown in Figure 7 The crystallization member 223 includes a crystallization part 2231, a rotating shaft 2232, and a flow guide part 2233, the crystallization part 2231 is formed with a cooling cavity capable of accommodating the flow guide part 2233, the crystallization part 2231 is arranged in a cylindrical shape matching the shape of the flow guide part 2233, the flow guide part 2233 is arranged in multiple and uniformly fixed along the extension direction of the rotating shaft 2232, the rotating shaft 2232 extends in the cooling cavity and is arranged to be capable of axially penetrating the water inlet member 221 and the water outlet member 222.

[0041] In some embodiments, as shown in Figure 7 The two bottom surfaces of the cylindrical crystallization part 2231 are fixed with the water inlet member 221 and the water outlet member 222 respectively, so that the water inlet member 221 and the water outlet member 222 are in communication with the cooling cavity, thereby realizing the following cooling process: the cooling medium enters the cooling cavity from the water inlet member 221 and exchanges heat with the crystallization part 2231 in the accommodating cavity, so as to flow out of the cooling cavity from the water outlet member 222.

[0042] In some embodiments, the flow guide part 2233 is arranged in a defective circular ring shape, the hollow part of the circular ring is arranged to allow the rotating shaft 2232 to pass through and be fixed, and the circular ring part is arranged to have a notch formed on the circumferential outer edge, so as to avoid forming a closed space between the flow guide parts 2233, to allow the cooling medium to flow in the cooling cavity.

[0043] In some embodiments, as shown in Figure 7 The rotating shaft 2232 is arranged to be capable of axial rotation, thereby driving the multiple flow guide parts 2233 to rotate axially, and further driving the crystallization part 2231 to rotate axially, so that the crystallization part 2231 can continuously receive the molten material dropping from the dripping assembly 21, and the material condensed on the crystallization part 2231 can be continuously scraped off by the scraping member 231.

[0044] In some embodiments, as shown in Figure 6 The scraping member 231 is arranged in a plate-like structure, the scraping fixing member 232 is arranged to contact different surfaces of the plate-like structure to fix the scraping member 231 in the direction perpendicular to the extension direction of the plate-like structure, to avoid displacement or deformation of the scraping member 231 caused by the relative movement mechanical force, and the extension length of the plate-like structure is arranged to be greater than or equal to the axial length of the crystallization part 2231.

[0045] In some embodiments, the plate-shaped structure is arranged to be capable of abutting against the cooling assembly 22 at one end, so that the plate-shaped structure can maintain continuous contact with the cooling assembly 22 when the cooling assembly 22 moves relatively, to scrape off the sheet material condensed on the surface of the cooling assembly 22.

[0046] In some embodiments, the scraping fixing member 232 can be arranged as a plurality of fixing rods, both ends of the fixing rods are fixed to the scraping collecting member 233, and the plurality of fixing rods are arranged to be staggered along different surfaces of the scraping member 231, to clamp and reinforce the plate-shaped structure in a direction perpendicular to the extension plane of the plate-shaped structure, prevent the plate-shaped structure from deviating from the original position for a long time under the mechanical action of the condensed material, and ensure the stability of the scraping effect.

[0047] In some embodiments, the plate-shaped structure has an extension length not less than the axial length of the crystallization part 2231, so that the extension range of the plate-shaped structure can cover the axial extension range of the crystallization part 2231, thereby being capable of scraping off all the condensed material on the crystallization part 2231 and preventing omission of the condensed material that needs to be scraped off.

[0048] In some embodiments, as shown in Figure 5 the scraping collecting member 233 is formed with a first opening and a second opening, the first opening and the second opening are arranged coaxially and in communication, the second opening is smaller than the first opening, the first opening is arranged close to the shunting assembly 21, and the second opening is arranged close to and in communication with the storage assembly 24.

[0049] In some embodiments, as shown in Figure 5 the scraping collecting member 233 is arranged to have an extension range in the vertical direction greater than that of the crystallization part 223, the part of the scraping collecting member 233 close to the first opening can avoid the sheet material in the molten state from splashing around when the sheet material in the molten state drops on the crystallization part 223, to prevent pollution of the operating environment; at the same time, the part of the scraping collecting member 233 close to the second opening can form an inward collecting structure, so that the scraped sheet material is gathered together, thereby falling smoothly into the storage assembly 24, to prevent the material from spilling.

[0050] Figure 8 a partial structure schematic view of the transition part and the shunting part provided by the embodiments of the present application is shown, in some embodiments, as shown in Figure 5 and Figure 8As shown, the diversion component 21 includes a temporary storage component 211, a transition component 212, a diversion component 213, and a heat preservation component 214. The transition component 212 is configured to connect the temporary storage component 211 and the diversion component 213 to allow the molten material to 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.

[0051] 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.

[0052] 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.

[0053] In some embodiments, the plurality of diverters 213 are configured in a funnel shape so that the molten material can flow out in droplets.

[0054] 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.

[0055] Another aspect of the embodiments of this application provides a material handling apparatus. Figure 9 This illustration shows a schematic diagram of the assembly of various components of the material handling equipment provided in an embodiment of this application, as shown below. Figure 9 As shown, it includes the aforementioned granulation device 2, stirring device 3, feeding device 4, material transfer device 1, transfer device 6 and body 5. The feeding device 4, material transfer device 1, granulation device 2 and transfer device 6 are fixed to the body 5, and the stirring device 3 is connected to the feeding device 4.

[0056] The material processing equipment provided by the embodiments of the present application can make the material transfer and processing in the space formed by the body 5, and the processing procedures do not interfere with each other, so that the material processing process is efficient and harmonious.

[0057] In some embodiments, as shown in Figure 9 The body 5 forms a containing space, the stirring device 3 is arranged outside the containing space and is arranged to be capable of mixing different kinds of powdery materials, the feeding device 4 is arranged in fixed connection with the body 5 and is arranged to be capable of delivering the mixed powdery materials to the material transfer device 1, the material transfer device 1 is arranged in the body 5 and is arranged to be capable of changing the mixed powdery materials into molten materials and transferring the molten materials, the material transfer device 1 is arranged to be capable of extending into the glove box, the granulating device 2 is arranged in the glove box and is in fixed connection with the body 5, and is arranged to be capable of receiving the molten materials from the material transfer device 1 and changing the molten materials into sheet materials, and the transfer device 6 is arranged in the glove box and is in fixed connection with the body 5, and is arranged to be in communication with the material outlet of the glove box to move the sheet materials out of the glove box. The powdery materials are changed into molten materials by the material transfer device 1, and the molten materials are transferred to the granulating device 2, so that the molten materials are changed into solid sheet materials by the granulating device 2, to realize the change of the materials from powdery to sheet, facilitating transportation and subsequent processing; since the powdery materials are not exposed to the air in the feeding device 4, the stirring device 3 and the material transfer device 1, and the granulating device 2 and the transfer device 6 are arranged in the glove box, the final output sheet materials can be prevented from being directly exposed to the air, the materials can be isolated from the operators, and the transfer device arranged in communication with the material outlet can facilitate the operators to collect and transfer the sheet materials.

[0058] In some embodiments, as shown in Figure 9 The body 5 includes a material processing support assembly 51, a feeding support assembly 52, a granulating support assembly 53 and a transfer support assembly 54, the material processing support assembly 51 and the feeding support assembly 52 are arranged in one piece and are formed with a double-layer space, the material transfer device 1 is arranged in the double-layer space and is in fixed connection with the material processing support assembly 51, the feeding device 4 is arranged outside the double-layer space and is in fixed connection with the feeding support assembly 52, the granulating support assembly 53 and the transfer support assembly 54 are arranged in the glove box 7 and are in fixed connection with the glove box 7, the granulating support assembly 53 and the transfer support assembly 54 divide the glove box 7 into four layers of space, the granulating device 2 and the transfer device 6 are arranged to extend in the four layers of space, the granulating device 2 is in fixed connection with the granulating support assembly 53, and the transfer device 6 is in fixed connection with the transfer support assembly 54.

[0059] In some embodiments, as shown in Figure 9 The material processing support assembly 51, the feeding support assembly 52, the granulation support assembly 53, and the transfer support assembly 54 can be arranged in a cubic frame, in which the material processing support assembly 51 and the feeding support assembly 52 are sequentially fixed and connected in a top-down order in the vertical direction to form a double-layer space; the granulation support assembly 53 and the transfer support assembly 54 are both fixed in the glove box 7 and sequentially fixed and connected in a top-down order in the vertical direction to jointly form a four-layer space with the glove box 7.

[0060] Figure 11 A cross-sectional view of the body provided by the embodiments of the present application is shown. In some embodiments, as shown in Figure 11 The double-layer space is arranged side by side with the glove box 7, and 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.

[0061] In some embodiments, the arrangement of the double-layer space side by side with the glove box 7 can shorten the transportation path of the material from the material transfer device 1 to the granulation device 2, thereby improving the material flow rate.

[0062] Figure 1 A schematic view of the assembly of the components of the material transfer device provided by the embodiments of the present application is shown. In some embodiments, as shown in Figure 1 , Figure 9 and Figure 11 The material transfer device 1 includes a material processing assembly 11, a pressurization assembly 12, and a transfer assembly 13. The material processing assembly 11 forms a material containing space for containing a powder material. The material processing assembly 11 is arranged to convert the powder material into a molten material. The material processing assembly 11 is arranged to communicate with the pressurization assembly 12 and the transfer assembly 13, respectively. The material processing assembly 11 is fixed to the material processing support assembly 51 and extends in the second space 200. The pressurization assembly 12 is arranged outside the containing space and is arranged to communicate with the material processing assembly 11. The transfer assembly 13 extends from the second space 200 into the four-layer space.

[0063] In some embodiments, the material processing assembly 11 is arranged to extend in the second space. The first space 100 serves to raise the height of the material processing assembly 11, so that the transfer assembly 13 can connect the material processing assembly 11 and the granulation device 2, thereby shortening the material flow path.

[0064] 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.

[0065] In some implementations, the pressurizing component 12 is configured to apply pressure to the material receiving space after the powdered material is transformed into a molten state, thereby moving the molten material to the transfer component 13. Both the pressurizing component 12 and the transfer component 13 are configured to maintain the molten material in a molten state. 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 configuration avoids moving the material handling component 11, achieving material transfer solely through gas pressurization, simplifying device components and operating steps; it also avoids direct contact between the molten material and air, prevents the molten material from reacting with 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, thus ensuring smooth material transfer.

[0066] 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.

[0067] 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.

[0068] In some embodiments, such as Figure 9 and Figure 11As shown, the granulation support assembly 53 includes a diversion support 531, a scraping support 532, and a collection support 533, and is arranged to extend in sequence in the height direction of the glove box 7. The diversion support 531 forms the third space 300 with the top of the glove box 7. The transfer support assembly 54 forms the sixth space 600 with the bottom of the glove box 7. The scraping support 532 forms the fourth space 400 with the diversion support 531. The scraping support 532 forms the fifth space 500 with the transfer support assembly 54. The collection support 533 is arranged to be fixed to the scraping support 532.

[0069] In some embodiments, the material is subjected to falling movement in the glove box 7. Therefore, the glove box 7 needs to extend to a predetermined height to ensure that sufficient space is reserved for the falling movement of the material.

[0070] Figure 12 As shown in the partial detail view of the granulation device provided by the embodiments of the present application, in some embodiments, the diversion assembly 21 is arranged to be fixed to the diversion support 531 and to extend in the third space 300 and the fourth space 400. The scraping assembly 23 is arranged to be fixed to the scraping support 532 and to extend in the fourth space 400 and the fifth space 500. The cooling assembly 22 is arranged to be able to pass through the scraping assembly 23. The storage assembly 24 is arranged to be fixed to the collection support 533 and to extend in the fifth space 500. Figure 5 Figure 11 Figure 12 As shown, the collection support 533 is arranged to be integrally formed with the scraping support 532 to carry and limit the movement of the storage assembly 24, so that the storage assembly 24 can comprehensively collect the sheet material scraped from the cooling assembly 22 by the scraping assembly 23.

[0071] In some embodiments, the diversion support 531 is used to support the weight of the diversion assembly 21. As shown, the collection support 533 is arranged to be integrally formed with the scraping support 532 to carry and limit the movement of the storage assembly 24, so that the storage assembly 24 can comprehensively collect the sheet material scraped from the cooling assembly 22 by the scraping assembly 23. Figure 12
