The scope of protection of the present invention shall be determined by the appended claims.

[0045] See also Figure 1 , Figure 1 1 is a schematic diagram of an exploded view of a drying device 1000 provided in an embodiment of the present application. The drying device 1000 includes a heating component 100 and a stirring component 200. The stirring component 200 is rotatably connected to the heating component 100. The heating component 100 is used to dry the material, and the stirring component 200 is used to stir the material. Thus, the stirring component 200 can evenly distribute the material to be dried in the drying device 1000 inside the drying device 1000, so that the material to be dried can be deeply dried.

[0046] It should be noted that Figure 1 The purpose is only to schematically describe the arrangement of the heating component 100 and the stirring component 200, and it is not to specifically limit the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the drying device 1000 is only shown in the embodiment of the present application, and does not constitute a specific limitation on the drying device 1000. In other embodiments of the present application, the drying device 1000 may include Figure 1 More or fewer components, or combinations of certain components, or different components, such as the drying device 1000 may also include but are not limited to dust removal equipment, etc. The dust removal equipment may be used to remove fine powder generated during the heating process of the heated material to prevent the fine powder in the heated material from affecting the life of the battery product.

[0047] Please also read Figure 1 and Figure 2 , Figure 2 1 is a schematic diagram of the structure of the heating component 100 of the drying device 1000 provided in an embodiment of the present application. The heating component 100 includes a drying cylinder 11 and at least two electromagnetic heating elements 13. A drying chamber 1101 is provided in the drying cylinder 11, and the drying cylinder 11 is configured as a magnetic conductive structure. At least two electromagnetic heating elements 13 are arranged flat on the outside of the drying chamber 1101, and can be independently disassembled and assembled with the drying cylinder 11. At least two electromagnetic heating elements 13 work independently of each other, and are used to generate a magnetic field to heat the drying cylinder 11 when powered on.

[0048] The drying device 1000 provided in the present application, on the one hand, is based on the fact that at least two electromagnetic heating elements 13 are laid out on the outside of the drying chamber 1101, and can be independently disassembled and assembled with the drying cylinder 11, so as to facilitate the assembly, disassembly and maintenance operations between the electromagnetic heating elements 13 and the drying cylinder 11, and realize the modular setting of each electromagnetic heating element 13 outside the drying cylinder 11, so that various electromagnetic heating elements 13 can be flexibly combined according to different needs of customers to meet the different needs of different customers, thereby improving product flexibility, and the modular design simplifies the production process, making the production more efficient; on the other hand, in the drying chamber 110 of the drying cylinder 11, the electromagnetic heating elements 13 can be arranged in a modular manner. At least two electromagnetic heating elements 13 are arranged outside the drying drum 11, and the drying drum 11 is configured as a magnetic conductive structure, so that the electromagnetic heating element 13 performs electromagnetic heating on the drying drum 11, thereby improving the heating speed, shortening the heating time, improving the energy saving effect, and improving the precise control of the heating temperature; on the other hand, based on the arrangement of at least two electromagnetic heating elements 13 working independently of each other, different electromagnetic heating elements 13 can work at different frequencies, thereby meeting the requirement that the drum body heats materials in different areas at different temperatures, and realizing intelligent control and flexible adjustment of the operating number of the electromagnetic heating elements 13, thereby realizing effective use of energy and cost saving.

[0049] It should be noted that the principle of electromagnetic heating is that the alternating current generated by the induction heating power supply generates an alternating magnetic field through an inductor (i.e., a coil), and a magnetically conductive object is placed therein to cut the alternating magnetic field lines, thereby generating an alternating current (i.e., eddy current) inside the object. Eddy current is the high-speed irregular movement of atoms inside the object, and the atoms collide and rub against each other to generate heat energy, thereby achieving the effect of heating the object. For example, in this embodiment, the drying chamber 1101 contains the material to be dried, and the electromagnetic heating element 13 generates an alternating magnetic field under the action of the alternating current. The drying cylinder 11 is used to cut the alternating magnetic field lines generated by the electromagnetic heating element 13, thereby achieving the effect of heating the drying cylinder 11. After the drying cylinder 11 is heated, the material in the drying chamber 1101 can be fully contacted with the hot air to complete the drying process, thereby achieving the drying device 1000 to dry the material by heating and rapidly evaporating water.

[0050] Illustratively, in the present embodiment, the drying device 1000 is configured as a plowshare drying device. The drying cylinder 11 is used to accommodate the material to be dried. In the present embodiment, the material to be dried is a battery material. Battery materials include a variety of materials, such as but not limited to active substances, conductive powders, binder powders, and the like. In the present embodiment, the drying device 1000 is illustrated with battery materials. It can be understood that the drying device 1000 can also be used to prepare its materials, such as food, medicine, fertilizer, building materials, etc., and the application of the drying device 1000 is not limited here. The plowshare drying device is a horizontal plowshare drying device. Of course, in some embodiments, the plowshare drying device can also be a vertical plowshare drying device.

[0051] It is understandable that, due to the large volume of the drying cylinder 11 of the plow drying equipment, and the outer wall of the drying cylinder 11 parallel to the axial direction X of the drying cylinder 11 is provided with multiple functional units, so that the outer wall of the drying cylinder 11 is incomplete, which increases the difficulty of assembling the electromagnetic heating element 13 and the drying cylinder 11, and the maintenance and replacement of the electromagnetic heating element 13 are inconvenient. In the embodiment of the present application, by laying at least two electromagnetic heating elements 13 on the outside of the drying chamber 1101 and being independently disassembled and assembled with the drying cylinder 11, on the one hand, it is convenient to assemble, disassemble and maintain the electromagnetic heating element 13 and the drying cylinder 11; on the other hand, it is possible to realize modular arrangement of each electromagnetic heating element 13 outside the drying cylinder 11, so as to flexibly combine various electromagnetic heating elements 13 according to different needs of customers, meet the different needs of different customers, improve product flexibility, and simplify the production process by modular design, making production more efficient.

[0052] Please refer again Figure 1 and Figure 2The stirring member 200 includes a rotating shaft 20 and a plurality of stirring blades 40 disposed on the rotating shaft 20. The rotating shaft 20 is rotatably connected to the drying cylinder 11 and is used to drive the stirring blades 40 to rotate so as to stir the material to be dried in the drying cylinder 11. The stirring blades 40 can evenly distribute the material to be dried in the drying cylinder 11 inside the dryer, so that the material to be dried can be deeply dried.

[0053] Exemplarily, in the present embodiment, two mounting holes 1106 are provided at both ends of the drying cylinder 11 along the axial direction X of the drying cylinder 11. The two ends of the rotating shaft 20 are rotatably mounted in the mounting holes 1106 respectively. A plurality of stirring blades 40 are arranged at intervals along the axial direction X of the rotating shaft 20. The installation directions of at least some of the stirring blades 40 on the rotating shaft 20 are different. It should be noted that the installation direction of the stirring blade 40 on the rotating shaft 20 refers to the inclination direction of the plane where the plow blade of the stirring blade 40 is located relative to the specific projection plane in a specific projection plane. The specific projection plane is user-defined, for example, the specific projection plane is Figure 1 The viewing angle plane, that is, the specific projection plane is a projection plane parallel to the central axis of the rotating shaft 20 and perpendicular to the feeding direction of the drying device 1000.

[0054] The drying device 1000 also includes a driving member. The driving member is arranged outside the drying cylinder 11 and is in driving connection with the rotating shaft 20. The working principle of the plowshare drying device is as follows: the material is transported into the drying cylinder 11, and the rotating shaft 20 is driven to rotate by the driving member, so that the stirring blade 40 on the rotating shaft 20 rotates in the drying cylinder 11, and the material in the drying cylinder 11 is thrown up along the inner wall of the drying cylinder 11 by the stirring blade 40, so as to ensure that the material is in full contact with the inner wall of the drying cylinder 11, increase the heating area between the material and the inner wall of the drying cylinder 11, and improve the drying efficiency of the material.

[0055] The top of the drying cylinder 11 is provided with a feed channel 1102 connected to the drying chamber 1101, so that the material to be dried can quickly enter the drying cylinder 11 under the action of gravity, thereby improving the conveying efficiency of the material to be ground. The central axis of the feed channel 1102 is inclined upward relative to the central axis of the drying cylinder 11. For example, the central axis of the feed channel 1102 can be vertically arranged with respect to the central axis of the drying cylinder 11; or, the central axis of the feed channel 1102 can be arranged with respect to the central axis of the drying cylinder 11 at an acute angle, which is not specifically limited in the embodiments of the present application.

[0056] For example, in the present embodiment, the feed channel 1102 is disposed at the middle of the top wall of the drying cylinder 11 along the axial direction X of the grinding cylinder, so that the material to be dried in the drying cylinder 11 reciprocates from the feed channel 1102 toward the two ends of the grinding cylinder along the axial direction X of the grinding cylinder under the stirring action of the stirring component 200, so as to form two circulation paths for the material to be dried in the drying cylinder 11, thereby improving the heat exchange effect between the material to be dried and the drying cylinder 11. Of course, in some embodiments, the feed channel 1102 is disposed at one of the ends of the top wall of the drying cylinder 11 along the axial direction X of the grinding cylinder, so that the material to be dried in the drying cylinder 11 reciprocates from the feed channel 1102 toward the end of the grinding cylinder along the axial direction X of the grinding cylinder, and away from the feed channel 1102, under the stirring action of the stirring component 200, so as to form a circulation path for the material to be dried in the drying cylinder 11.

[0057] Please also read Figure 2 and Figure 3 , Figure 3 yes Figure 1 Schematic diagram of an axial cross-section of the heating component 100 of the drying device 1000 in the figure. A discharge channel 1103 connected to the drying chamber 1101 is provided at the bottom of the drying cylinder 11, so that the dried material can be quickly discharged from the discharge channel 1103 from the drying cylinder 11 under the action of gravity, thereby improving the discharge efficiency of the material. The central axis of the discharge channel 1103 is inclined upward relative to the central axis of the drying cylinder 11. For example, the central axis of the discharge channel 1103 can be vertically arranged with respect to the central axis of the drying cylinder 11; or, the central axis of the discharge channel 1103 can also be arranged at an acute angle with respect to the central axis of the drying cylinder 11, which is not specifically limited in the embodiments of the present application.

[0058] For example, in this embodiment, the discharge channel 1103 is arranged at the middle of the bottom wall of the drying cylinder 11 along the axial direction X of the grinding cylinder, so that the dried material in the drying cylinder 11 moves from both ends of the grinding cylinder along the axial direction X of the grinding cylinder toward the discharge channel 1103 under the stirring action of the stirring member 200, thereby improving the discharge efficiency of the dried material. Of course, in some embodiments, the discharge channel 1103 is arranged at one end of the bottom wall of the drying cylinder 11 along the axial direction X of the grinding cylinder, and the embodiment of the present application does not make specific limitations.

[0059] The drying device 1000 further includes a discharge valve 111. The discharge valve 111 is disposed at a position corresponding to the discharge channel 1103. The discharge valve 111 is used to open or close the discharge channel 1103. The discharge valve 111 is sealedly connected to the drying cylinder 11, thereby avoiding the problem of material leakage.

[0060] In some embodiments, the drying device 1000 is also provided with a connecting channel 1104 connected to the drying chamber 1101. The connecting channel 1104 is used to install a dust removal device. In some embodiments, the drying device 1000 also includes a vacuum pump. The vacuum pump evacuates the dust removal device to separate water vapor from the material. Thus, the provision of the vacuum pump can reduce drying energy consumption and improve drying efficiency. Exemplarily, the connecting channel 1104 is provided in two. Along the axial direction X of the grinding cylinder, the two connecting channels 1104 are located on both sides of the feed channel 1102, that is, the discharge channel 1103 is located between the two connecting channels 1104. Of course, in some embodiments, the connecting channel 1104 can also be provided in one, three or more than three, which is not specifically limited in the embodiments of the present application.

[0061] Exemplarily, in the present embodiment, the drying cylinder 11 is configured with a cylindrical cylinder body, thereby improving the smoothness of the movement of the material to be dried in the drying cylinder 11, improving the heat exchange efficiency between the material to be dried and the drying cylinder 11, improving the drying efficiency and drying effect of the drying device 1000, and reducing the wear of the drying cylinder 11, thereby extending the service life of the drying cylinder 11. The outer shape of the radial cross section of the drying cylinder 11 is circular. Of course, in some embodiments, the drying cylinder 11 can also be configured as, but not limited to, a spherical cylinder body, a prismatic cylinder body or other regular or irregular cylinder bodies, which is not specifically limited in the present embodiment of the application. The outer shape of the radial cross section of the drying cylinder 11 can also be semicircular, elliptical, square, polygonal, etc.

[0062] For the accuracy of description, please refer to the directions in this article. Figure 2 For reference, "axial direction X" refers to the direction parallel to the central axis of the drying cylinder 11, that is, the left-right direction (where the positive direction of the X-axis is left); the term "radial direction Y" refers to the direction perpendicular to the central axis of the drying cylinder 11, that is, the radial direction along the cross-section of the drying cylinder 11; the term "circumferential direction Z" refers to the circumferential direction of the drying cylinder 11, that is, the direction surrounding the central axis of the drying cylinder 11, wherein the axial direction X, radial direction Y and circumferential direction Z together constitute the three orthogonal directions of the drying cylinder 11. The axial direction X, radial direction Y and circumferential direction Z of the drying cylinder 11 can be customized according to the specific structure of the product and the perspective of the drawings, and this application does not make specific restrictions. For the convenience of description, the directions of up, down, left, right, front and back in this application are relative positions and do not constitute restrictions on implementation.

[0063] In some embodiments, all electromagnetic heating elements 13 work independently of each other, that is, all electromagnetic heating elements 13 are connected in parallel, so that each electromagnetic heating element 13 can work independently of each other without affecting each other. In other embodiments, some electromagnetic heating elements 13 work independently of each other, and some electromagnetic heating elements 13 work in association with each other. In other words, some electromagnetic heating elements 13 are connected in parallel, and the remaining electromagnetic heating elements 13 are connected in series. In other embodiments, all electromagnetic heating elements 13 work in association with each other.

[0064] Please also read Figure 1 , Figure 3 and Figure 4 , Figure 4 yes Figure 1 Schematic diagram of a radial cross section of a heating component 100 of a drying device 1000 in the embodiment. Exemplarily, in the present embodiment, four electromagnetic heating elements 13 are provided, two of the four electromagnetic heating elements 13 are located at the bottom wall of the drying cylinder 11, and are arranged along the axial direction X of the drying cylinder 11, and the other two of the four electromagnetic heating elements 13 are located at the front side wall and the rear side wall of the drying cylinder 11, respectively. It can be understood that since a feed channel 1102 and a connecting channel 1104 are provided at the top of the drying cylinder 11, and a discharge channel 1103 is provided at the bottom of the drying cylinder 11, the outer wall of the drying cylinder 11 is incomplete. Therefore, the embodiment of the present application arranges electromagnetic heating elements 13 in different areas of the drying cylinder 11, fully utilizing the space of the outer wall of the drying cylinder 11, thereby improving the compactness of the overall structure of the drying device 1000, and improving the heating effect and heating efficiency of the drying device 1000.

[0065] In some embodiments, there are two electromagnetic heating elements 13, both of which are located on the bottom wall of the drying cylinder 11 and arranged along the axial direction X of the drying cylinder 11; or, one of the two electromagnetic heating elements 13 is located on the bottom wall of the drying cylinder 11, and the other of the two electromagnetic heating elements 13 is located on the front side wall or the rear side wall of the drying cylinder 11; or, one of the two electromagnetic heating elements 13 is located on the front side wall of the drying cylinder 11, and the other of the two electromagnetic heating elements 13 is located on the rear side wall of the drying cylinder 11.

[0066] In some embodiments, there are three electromagnetic heating elements 13, two of which are located on the bottom wall of the drying cylinder 11 and are arranged along the axial direction X of the drying cylinder 11, and another one of which is located on the front side wall or the rear side wall of the drying cylinder 11; or, the three electromagnetic heating elements 13 are respectively located on the bottom wall, the front side wall and the rear side wall of the drying cylinder 11.

[0067] The drying device 1000 also includes a mounting shell 14. The mounting shell 14 is disposed outside the drying chamber 1101 and forms at least two mounting chambers 120 with the drying cylinder 11. The at least two mounting chambers 120 are disposed independently of each other, and at least one electromagnetic heating element 13 is disposed in each mounting chamber 120. Since the at least two mounting chambers 120 are disposed independently of each other, the mounting shell 14 can reduce the risk of electromagnetic leakage in each mounting chamber 120, and prevent the electromagnetic heating elements 13 in different mounting chambers 120 from crosstalk, thereby improving the flexibility of regulating the heating temperature of different heating areas, and avoiding the problem that some electromagnetic heating elements 13 fail and cannot heat and dry the material to be dried.

[0068] For example, a discharge channel 1103 is also provided in the middle of the bottom wall of the drying cylinder 11, and the electromagnetic heating element 13 includes two first electromagnetic heating bodies 131, and the two first electromagnetic heating bodies 131 are both located on the bottom wall of the drying cylinder 11. In the axial direction X of the drying cylinder 11, the two first electromagnetic heating bodies 131 are symmetrically arranged relative to the discharge channel 1103, wherein the two first electromagnetic heating bodies 131 work in association with each other; or, the two first electromagnetic heating bodies 131 work independently of each other. Therefore, on the one hand, based on the fact that two first electromagnetic heating bodies 131 are arranged on the bottom wall of the drying cylinder 11, the heat exchange time between the material to be dried in the drying cylinder 11 and the bottom wall of the drying cylinder 11 is increased, and at the same time, the heating area of ​​the bottom area of ​​the drying cylinder 11 for heating the material to be dried is increased, thereby improving the drying effect and drying efficiency of the drying equipment 1000 on the material; on the other hand, based on the fact that the two first electromagnetic heating bodies 131 work in association with each other, the synchronization of the work of the two first electromagnetic heating bodies 131 is ensured, thereby making the heating uniformity of the bottom area of ​​the drying cylinder 11, thereby improving the drying effect of the drying cylinder 11 on the material to be dried and improving the quality of the material. Of course, in some embodiments, the two first electromagnetic heating bodies 131 are arranged independently of each other, so that the two first electromagnetic heating bodies 131 work independently of each other and do not affect each other, thereby improving the flexibility of heating the local area of ​​the drying cylinder 11, and avoiding the problem that one electromagnetic heating element 13 fails and cannot heat and dry the material to be dried.

[0069] Exemplarily, in this embodiment, the mounting shell 14 includes a first shell 141. The first shell 141 is located at the bottom of the drying cylinder 11 and is connected to the drying cylinder 11 to form a first cavity 1201. The two first electromagnetic heating bodies 131 are both disposed in the first cavity 1201. In this way, the first shell 141 and the two first electromagnetic heating bodies 131 are integrated into an integral structure to improve assembly efficiency.

[0070] Of course, in some embodiments, the mounting shell 14 includes two first shells 141. The two first shells 141 are both located at the bottom of the drying cylinder 11 and are connected to the drying cylinder 11 to form two first cavities 1201 that are independently arranged. The two first electromagnetic heating bodies 131 are respectively arranged in the two first cavities 1201. Thus, based on the fact that the two first cavities 1201 are independently arranged, and the two first electromagnetic heating bodies 131 are respectively arranged in the two first cavities 1201, so that the two first electromagnetic heating bodies 131 are isolated from each other in the two first cavities 1201, the risk of electromagnetic leakage in the two first cavities 1201 is reduced, and the two first electromagnetic heating bodies 131 are prevented from crosstalk, which improves the flexibility of regulating the heating temperature of different heating areas, and avoids the problem that one first electromagnetic heating body 131 fails and cannot heat and dry the material to be dried.

[0071] In some embodiments, the mounting shell 14 includes a second shell 142. The second shell 142 is located at the front side of the drying cylinder 11 and is connected to the drying cylinder 11 to form a second cavity 1202. The electromagnetic heating element 13 also includes a second electromagnetic heating body 132. The second electromagnetic heating body 132 is arranged in the second cavity 1202, wherein the second cavity 1202 and the first cavity 1201 are arranged independently of each other; and / or, the mounting shell 14 includes a third shell 143, the third shell 143 is located at the rear side of the drying cylinder 11, and is connected to the drying cylinder 11 to form a third cavity 1203. The electromagnetic heating element 13 also includes a third electromagnetic heating body 133, and the third electromagnetic heating body 133 is arranged in the third cavity 1203, wherein the third cavity 1203 and the first cavity 1201 are arranged independently of each other. Therefore, based on the fact that at least one of the second cavity 1202 and the third cavity 1203 is independently set with the first cavity 1201, and at least one of the second electromagnetic heating body 132 and the third electromagnetic heating body 133 and the first electromagnetic heating body 131 are respectively set in different installation cavities 120, so that at least one of the second electromagnetic heating body 132 and the third electromagnetic heating body 133 and the first electromagnetic heating body 131 are isolated from each other in different installation cavities 120, thereby reducing the risk of electromagnetic leakage in the second cavity 1202 and the third cavity 1203 and the first cavity 1201, and preventing the second electromagnetic heating body 132 and the third electromagnetic heating body 133 from crosstalking with the first electromagnetic heating body 131, thereby improving the flexibility of regulating the heating temperature of different heating areas, and avoiding the problem that one electromagnetic heating element 13 fails and cannot heat and dry the material to be dried.

[0072] Exemplarily, in this embodiment, the first electromagnetic heating body 131, the second electromagnetic heating body 132 and the third electromagnetic heating body 133 work independently of each other. The first cavity 1201, the second cavity 1202 and the third cavity 1203 are set independently of each other, that is, any two of the first cavity 1201, the second cavity 1202 and the third cavity 1203 are isolated from each other. In this way, the first electromagnetic heating body 131, the second electromagnetic heating body 132 and the third electromagnetic heating body 133 are prevented from crosstalk, the flexibility of regulating the heating temperature of different heating areas is improved, and the problem of failure of one electromagnetic heating element 13 and inability to heat and dry the material to be dried is avoided.

[0073] In some embodiments, two of the first electromagnetic heating body 131, the second electromagnetic heating body 132, and the third electromagnetic heating body 133 work independently of each other, thereby improving the flexibility of regulating the heating temperature of different heating areas and avoiding the problem that one electromagnetic heating element 13 fails and cannot heat and dry the material to be dried. For example, the first electromagnetic heating body 131, the second electromagnetic heating body 132, and the third electromagnetic heating body 133 all work independently of each other; or any two of the first electromagnetic heating body 131, the second electromagnetic heating body 132, and the third electromagnetic heating body 133 work independently of each other.

[0074] In some embodiments, the drying device 1000 further includes a mounting shell 14. The mounting shell 14 is detachably connected to the drying cylinder 11. At least one mounting shell 14 is provided, and each mounting shell 14 is connected to at least one electromagnetic heating element 13 to form an integral structure. Thus, on the one hand, the mounting shell 14 is detachably connected to the drying cylinder 11, thereby facilitating assembly, maintenance, replacement and other operations; on the other hand, each mounting shell 14 is connected to at least one electromagnetic heating element 13 to form an integral structure, thereby improving the integration of the electromagnetic heating element 13 and the mounting shell 14, simplifying the structural setting, and saving space layout.

[0075] In some embodiments, the mounting shell 14 is configured as a magnetic isolation and heat insulation structure; and / or, an insulating heat insulation layer is provided on the mounting shell 14. Thus, based on configuring the mounting seat 145 as a magnetic isolation structure, the mounting shell 14 is prevented from electromagnetically heating, and the temperature is prevented from being transferred to the outside to scald the operator, thereby improving the use safety of the drying device 1000; on the other hand, based on configuring the mounting shell 14 as a magnetic isolation and heat insulation structure; or, the mounting shell 14 is provided with an insulating heat insulation layer, the temperature can be prevented from being transferred to the outside to scald the operator.

[0076] In some embodiments, the mounting shell 14 is provided with a mounting groove 1401 with an opening toward one side of the drying cylinder 11. The mounting groove 1401 is used to install at least two electromagnetic heating elements 13. Thus, based on the mounting groove 1401 with an opening toward one side of the drying cylinder 11 provided in the mounting shell 14, the assembly of the electromagnetic heating element 13 is facilitated, and the cutting alternating magnetic field lines generated by the drying cylinder 11 on the electromagnetic heating element 13 are improved, thereby improving the heating effect of the electromagnetic heating element 13 on the drying cylinder 11. Exemplarily, in the present embodiment, the mounting shell 14 is provided in plurality, and each mounting shell 14 is provided with a mounting groove 1401 for installing the corresponding electromagnetic heating element 13. In the present embodiment, the mounting groove 1401 is configured as an arc groove, thereby increasing the installation area of ​​the electromagnetic heating element 13, improving the heating uniformity and heating effect, and facilitating the alignment assembly of the electromagnetic heating element 13, the mounting shell 14 and the drying cylinder 11. Of course, in some embodiments, the mounting groove 1401 can also be configured as a square groove.

[0077] The shape of the electromagnetic heating element 13 is adapted to the shape of the outer wall of the drying cylinder 11. Specifically, the drying cylinder 11 is configured as a cylindrical structure. The electromagnetic heating element 13 is arranged in a curved spiral along the circumferential direction of the drying cylinder 11. Exemplarily, in the present embodiment, each electromagnetic heating element 13 is arranged in a curved spiral in the mounting groove 1401, so as to improve the uniformity of heating the drying cylinder 11 by the electromagnetic heating element 13. Each electromagnetic heating element 13 includes a plurality of electromagnetic heating sections 130. The plurality of electromagnetic heating sections 130 are arranged in a curved manner around the outer contour of the drying cylinder 11. Therefore, on the one hand, the overall shape of the electromagnetic heating element 13 is compatible with the shape of the outer wall of the drying cylinder 11, thereby improving the alignment and assembly efficiency and assembly yield of the mounting shell 14 and the drying cylinder 11; on the other hand, based on the electromagnetic heating element 13 being arranged in a curved and spiral shape in the mounting groove 1401, and arranging a plurality of electromagnetic heating sections 130 curved around the outer contour of the drying cylinder 11, the radiation area of ​​the electromagnetic heating element 13 to the drying cylinder 11 is increased, the heating effect of the drying cylinder 11 is improved, the assembly is convenient, and the uniformity of heating and drying of the material by the drying cylinder 11 is improved, thereby improving the quality of the material.

[0078] The distance between the multiple electromagnetic heating sections 130 and the outer wall of the drying cylinder 11 is the same. Specifically, the multiple electromagnetic heating sections 130 include multiple axial heating sections extending along the axial direction X of the drying cylinder 11 and at least one circumferential heating section extending along the circumferential direction Z of the drying cylinder 11, and two adjacent axial heating sections are connected by the circumferential heating section. As a result, the number of bending times of the electromagnetic heating element 13 is reduced, the space utilization rate of the electromagnetic heating element 13 is improved, and the assembly of the electromagnetic heating element 13 is convenient. The drying cylinder 11 is configured as a cylindrical structure. The curvature of the electromagnetic heating section 130 is the same as that of the drying cylinder 11. Specifically, the multiple axial heating sections are all arranged on the same arc line with the same center as the drying cylinder 11. On a radial section perpendicular to the central axis of the drying cylinder 11, the line connecting the centers of the multiple axial heating sections is parallel to the circumferential direction Z of the drying cylinder 11.

The observation operation window 1105 and the at least two electromagnetic heating elements 13 are arranged at intervals along the circumferential direction Z of the drying cylinder 11. Therefore, on the one hand, the setting of the observation operation window 1105 can facilitate the staff to observe the drying condition of the material in the drying cylinder 11 and to facilitate the maintenance of the stirring blades in the drying cylinder 11; on the other hand, the electromagnetic heating element 13 is prevented from being exposed in the observation operation window 1105, thereby improving the compactness of the overall structure.

[0081] In this embodiment, two observation operation windows 1105 are provided, and the two observation operation windows 1105 are arranged at intervals along the axial direction X of the drying cylinder 11, thereby improving the overall structural strength of the drying cylinder 11 and facilitating the staff to inspect the stirring blades in the drying cylinder 11. It should be noted that the number of observation operation windows 1105 can be set according to actual conditions, and the embodiment of the present application does not make specific limitations. For example, the number of observation operation windows 1105 can also be one, three, or more than three.

[0082] An observation and operation door 112 is provided at the position of the drying cylinder 11 corresponding to the observation and operation window 1105. The observation and operation door 112 is used to close or open the observation and operation window 1105.

The observation and operation door 112 is reversibly connected to the drying cylinder 11, thereby facilitating the maintenance operation of the user and improving the sealing of the connection between the observation and operation door 112 and the drying cylinder 11. Of course, in some embodiments, the observation and operation door 112 and the drying cylinder 11 can also be slidably connected or detachably connected.

Figure 6 yes Figure 5 A cross-sectional view of the stirring member 200 along AA; Figure 7 yes Figure 5 Schematic diagram of the structure of the mounting mechanism 60 of the stirring component 200. Each stirring blade 40 includes a plow 50 and a mounting mechanism 60. The plow 50 is detachably fixedly connected to the rotating shaft 20 through the mounting mechanism 60. Therefore, based on the setting that the plow 50 is detachably fixedly connected to the mounting mechanism 60, it is convenient to assemble, repair, replace or clean the plow 50.

[0090] In the embodiment of the present application, the term "quick release" refers to the possibility of quick disassembly or quick disassembly between two connected or associated parts / elements; and the connection between two parts / elements connected in a quick disassembly / quick disassembly manner is called "quick release connection". Specifically, quick release may refer to the ability of the plow blade 50 and the mounting member 62 to be quickly disassembled or quickly assembled through the provided quick release assembly 63. Accordingly, the method of connecting in a quick release manner is also called a quick release connection. The first quick release member 64 and the second quick release member 65 refer to structures for realizing modularization of the various parts of the plow blade 50 and the mounting member 62, thereby enabling quick disassembly of the plow blade 50 and the mounting member 62.

Each mounting member 62 is provided with at least one quick-release hole 620 along the second direction F2. Each first quick-release member 64 is provided with a slot 6401. When the plow 50 is in a locked state, each second quick-release member 65 is engaged with the slot 6401 and locked in the corresponding quick-release hole 620 and the second connecting hole 5102, and each first quick-release member 64 is locked in the first connecting hole 5101. When the plow 50 is in an unlocked state, each second quick-release member 65 is disengaged from the slot 6401 and is removably provided in the corresponding quick-release hole 620 and the second connecting hole 5102, and each first quick-release member 64 is removably provided in the first connecting hole 5101. Therefore, on the one hand, based on the card slot 6401 of the first quick-release part 64, two first quick-release parts 64 are limited, so that the first quick-release part 64 and the second quick-release part 65 cooperate and snap together to achieve the purpose of fixed connection and locking between the plow blade 50 and the mounting part 62, thereby improving the stability and reliability of the connection between the plow blade 50 and the mounting part 62, avoiding the problem of loosening of the plow blade 50 and the mounting part 62 during the material drying process, and reducing labor costs, facilitating assembly, disassembly, replacement and maintenance, being flexible to use, and improving production efficiency; on the other hand, the first quick-release part 64 and the second quick-release part 65 cooperate and snap together, so that the structure of the mounting mechanism 60 is simple and compact, saving the occupied space of the mounting mechanism 60, and improving the use efficiency and flexibility of the mounting mechanism 60.

[0092] For example, in this embodiment, the number of quick-release holes 620 and the number of first connection holes 5101 are the same as the number of first quick-release parts 64, and are arranged in a one-to-one correspondence, and the number of second connection holes 5102 is the same as the number of second quick-release parts 65, and are arranged in a one-to-one correspondence. Of course, in some embodiments, the number of quick-release holes 620 is the same as the number of first connection holes 5101, and is arranged in a one-to-one correspondence, and is greater than the number of first quick-release parts 64, and the number of second connection holes 5102 is greater than the number of second quick-release parts 65, that is, the first quick-release part 64 and the second quick-release part 65 can respectively select the corresponding first connection hole 5101 and the second connection hole 5102 for connection.

[0093] In some embodiments, the mounting mechanism 60 further includes a connection seat 70. The connection seat 70 is used to be fixedly connected to the rotating shaft 20. For example, in the present embodiment, the connection seat 70 and the rotating shaft 20 are integrally formed, thereby improving the connection strength and connection reliability between the connection seat 70 and the rotating shaft 20, and improving the assembly and disassembly efficiency of the connection seat 70 and the rotating shaft 20. Of course, in some embodiments, the connection seat 70 and the rotating shaft 20 can also be detachably fixedly connected, thereby facilitating operations such as maintenance, replacement and cleaning of the connection seat 70 and the rotating shaft 20. The connection seat 70 and the rotating shaft 20 can be fixedly connected by a locking structure such as a screw or a buckle, which is not specifically limited in the present embodiment of the application.

[0094] The connecting seat 70 is provided with a receiving groove 701. The connecting portion 51 of the plow 50 is provided in the receiving groove 701. At least part of the structure of the two mounting members 62 is installed in the receiving groove 701. Along the second direction F2, one end of each mounting member 62 is connected to the connecting seat 70, and the other end of each mounting member 62 is connected to the connecting portion 51. Exemplarily, in the present embodiment, the connecting portion 51 of the plow 50 and the two mounting members 62 are pluggably installed in the receiving groove 701, so as to facilitate the alignment and assembly of the connecting seat 70 with the plow 50 and the two mounting members 62. Specifically, the two side walls of the connecting seat 70 along the second direction F2 are respectively provided with two limiting grooves 702 connected with the receiving groove 701. Each mounting member 62 is provided with a limiting structure 622 that slidably cooperates with the limiting groove 702.

[0095] For example, in this embodiment, the connection seat 70 and the two mounting members 62 are independently provided and detachably fixedly connected to each other, thereby facilitating the removal of the mounting member 62 and the plow 50 from the connection seat 70 and improving the efficiency of the disassembly and assembly of the plow 50.

[0096] In some embodiments, a disassembly structure 6203 is provided at one end of each mounting member 62 away from the rotating shaft 20. The disassembly structure 6203 is used to install a disassembly tool. Thus, by connecting the disassembly tool to the mounting member 62, it is convenient to disassemble the mounting member 62 and the plow 50 from the connecting seat 70, thereby improving the user experience. The disassembly tool may be, but is not limited to, a screw driver, a pliers-type tool, or a sleeve-type tool. Exemplarily, in the present embodiment, the disassembly structure 6203 is configured as a groove structure, such as a threaded hole, and the disassembly tool is a screw driver that cooperates with the threaded hole. Of course, in some embodiments, the disassembly structure 6203 can also be configured as a protruding structure to avoid material residue on the disassembly structure 6203. The disassembly structure 6203 can be set according to actual conditions, and the embodiments of the present application are not specifically limited.

[0097] For example, in this embodiment, the limiting groove 702 is configured as a T-shaped slide groove, and the limiting structure 622 is configured as a T-shaped slider. Therefore, based on the sliding cooperation between the T-shaped slide groove and the T-shaped slider, the connecting seat 70 can be limited and positioned in a certain dimension, thereby improving the stability and reliability of the connection between the coulter 50 and the mounting member 62. Of course, in some embodiments, the limiting groove 702 is configured as an L-shaped slide groove or a linear slide groove. The limiting structure 622 cooperates with the limiting groove 702, and the shape of the limiting groove 702 can be set according to actual conditions, and the embodiment of the present application does not make specific limitations.

[0098] A first through hole 703 is provided at a position of the connection base 70 corresponding to the first connection hole 5101. A second through hole 704 is provided at a position of the connection base 70 corresponding to the second connection hole 5102. When the coulter 50 enters a locked state, the first quick release member 64 is sequentially penetrated and locked in the first through hole 703 and the first connection hole 5101, and the second quick release member 65 is sequentially penetrated and locked in the second through hole 704, the quick release hole 620, the second connection hole 5102 and the slot 6401. When the coulter 50 enters an unlocked state, the first quick release member 64 is removably penetrated in the first through hole 703 and the first connection hole 5101, and the second quick release member 65 is removably penetrated in the second through hole 704, the quick release hole 620, the second connection hole 5102 and the slot 6401.

[0099] Please refer again Figure 6 , Figure 7 and Figure 8 , Figure 8 yes Figure 5Schematic diagram of the structure of the first quick release part 64 and the second quick release part 65 of the plow blade stirring component 200. In this embodiment, the card slot 6401 is an annular groove, which facilitates the processing and forming of the first quick release part 64 and reduces the installation requirements of the first quick release part 64. Of course, in some embodiments, the card slot 6401 can also be but not limited to an arc groove, a circular groove, a square groove, etc., which is not specifically limited in the embodiment of the present application. When the second quick release part 65 is inserted into the card slot 6401, the second quick release part 65 is locked on the connecting part 51.

[0100] At least one of the first quick release member 64 and the second quick release member 65 is configured as a latch rod. Of course, in some embodiments, at least one of the first quick release member 64 and the second quick release member 65 can also be configured as a screw or a bolt. Exemplarily, the first quick release member 64 and the second quick release member 65 each include a rod 641 and a rod head 642 connected to one end of the rod 641. The end of the rod 641 of the first quick release member 64 away from the rod head 642 is provided with a slot 6401.

[0101] In this embodiment, the radial cross-section of the shaft 641 is circular. The radial cross-section of the rod head 642 is circular. In other embodiments, the radial cross-section of the shaft 641 and the radial cross-section of the rod head 642 may also be, but not limited to, square, polygonal, etc. The shape of the first connecting hole 5101 and the shape of the second connecting hole 5102 are respectively matched with the shape of the first quick release part 64 and the shape of the second quick release part 65, thereby preventing the plow blade 50 from loosening relative to the mounting part 62, improving the smoothness of the plow blade 50 stirring, and reducing noise.

[0102] In some embodiments, the card slot 6401 includes a first slot and a second slot connected to the first slot, and the extension direction of the first slot is different from the extension direction of the second slot. For example, the card slot 6401 can also be set to a T-shape or an L-shape. A card block is provided at the end of the second quick-release member 65, and the card block cooperates with the card slot 6401. When the card block of the second quick-release member 65 rotates in the first slot and the second slot, the second quick-release member 65 is fixedly connected with the first quick-release member 64. When the card block of the second quick-release member 65 rotates in the first slot, the second quick-release member 65 and the first quick-release member 64 can be separated from the fixed connection.

[0103] In some embodiments, the mounting mechanism 60 further includes a gasket 66. The gasket 66 is sleeved on the rod body 641 and stops with the rod head 642. Therefore, on the one hand, the gasket 66 can provide a good sealing effect, prevent the material from entering the gap between the first quick release part 64 and the second quick release part 65 and the connection part 51 of the mounting part 62 and the plow blade 50, reduce wear and reduce material loss, and facilitate disassembly and assembly; on the other hand, the gasket 66 can absorb part of the vibration energy and slow down the impact between parts, thereby reducing the wear of the stirring component 200 and extending the service life of the stirring component 200; on the other hand, the gasket 66 can evenly disperse the pressure generated by the first quick release part 64 and the second quick release part 65, and prevent the first quick release part 64 and the second quick release part 65 from being deformed or damaged due to excessive local pressure during the installation process.

[0104] Please refer again Figure 5 and Fig. 9 , Fig. 9 yes Figure 5 The structural diagram of the mounting mechanism 60 and the plow blade 50 of the stirring component 200 is shown in FIG. A guide surface 5103 is provided at one end of the connecting portion 51 close to the rotating shaft 20, and the shape of the guide surface 5103 is adapted to the shape of the rotating shaft 20, thereby preventing the plow blade 50 from shaking with the rotating shaft 20 during the stirring of materials, reducing noise, and increasing the service life of the plow blade 50 and the rotating shaft 20.

[0105] In some embodiments, the plow 50 further includes a support portion 53 connected between the connection portion 51 and the stirring portion 52. Thus, the support portion 53 can support and fix the stirring portion 52, so as to facilitate adjustment of the distance between the plow 50 and the drying cylinder 11. A rounded structure 521 is provided at the edge of the stirring portion 52 of the plow 50, so as to effectively prevent the stirring component 200 from damaging the material due to high-speed rotation, causing the material to generate fine powder, and preventing the fine powder in the material from affecting the battery life.

[0106] Please also read Figure 6 , Figure 8 and Fig.10 , Fig.10 yes Figure 562 of the mounting member 62 of the stirring member 200 in the embodiment of the present invention. The second quick release member 65 includes a first connecting section 651 and a second connecting section 652. The radial dimension of the first connecting section 651 is smaller than the radial dimension of the second connecting section 652. The quick release hole 620 includes a first hole 6201 and a second hole 6202 connected to the first hole 6201. The radial dimension of the first hole 6201 is smaller than the radial dimension of the second hole 6202. The first connecting section 651 is removably provided in the first hole 6201. The second connecting section 652 is removably provided in the second hole 6202. When the plow 50 is in a locked state, each second quick release member 65 is locked in the first hole 6201, the second connecting hole 5102 and the slot 6401. When the plow 50 is in an unlocked state, each second quick release member 65 is removably provided in the second hole 6202, the second connecting hole 5102 and the slot 6401. It can be understood that when the second connecting section 652 is aligned with the second hole 6202, the second quick release component 65 can be pulled out from the slot 6401, the second connecting hole 5102 and the second hole 6202 in sequence, so that the plow 50 enters an unlocked state; when the second connecting section 652 is aligned with the first hole 6201, the second quick release component 65 is located outside the quick release hole 620 and is stopped at the position of the mounting component 62 corresponding to the limit of the first hole 6201, that is, the second quick release component 65 cannot be pulled out from the slot 6401, the second connecting hole 5102 and the second hole 6202, so that the plow 50 enters a locked state. Therefore, based on setting the second quick-release component 65 as the first connecting segment 651 and the second connecting segment 652 with different radial sizes, and setting the quick-release hole 620 as the first hole 6201 and the second hole 6202 with different apertures, when disassembling the plow 50, the user can move the mounting component 62 so that the second connecting segment 652 of the second quick-release component 65 is aligned with the second hole 6202, thereby enabling the user to pull out the second quick-release component 65 from the slot 6401, the second connecting hole 5102 and the second hole 6202, which makes it convenient for the user to disassemble the plow 50, conforms to the user's usage habits, and improves the user's operating experience.

[0107] The shaft 641 of the second quick release member 65 includes a first connection section 651 and a second connection section 652. The first connection section 651 is connected between the second connection section 652 and the rod head 642. In some embodiments, the rod head 642 of the second quick release member 65 is located outside the quick release hole 620, so that the rod head 642 can provide a user with a grip and operation function, making it convenient for the user to pull out the second quick release member 65, thereby improving the disassembly efficiency of the coulter 50.

[0108] For the accuracy of description, please refer to the directions in this article. Figure 6 and Figure 7 For reference, the “first direction F1” refers to a direction parallel to the insertion direction of the first quick release member 64, that is, Figure 6The term "second direction F2" refers to a direction parallel to the plugging direction of the second quick release member 65, that is, Figure 6 The term "third direction F3" refers to the arrangement direction of the first hole 6201 and the second hole 6202 of the quick release hole 620, that is, Figure 7 The up and down directions in the drying cylinder 11. The first direction F1, the second direction F2 and the third direction F3 together constitute the three orthogonal directions of the drying cylinder 11. The first direction F1, the second direction F2 and the third direction F3 of the drying cylinder 11 can be customized according to the specific structure of the product and the perspective of the drawings, and this application does not make specific restrictions. For the convenience of description, the directions such as up, down, left, right, front and back in this application are relative positions and do not constitute a limitation on the implementation.

[0109] For example, in this embodiment, the arrangement direction of the first hole 6201 and the second hole 6202 is parallel to the third direction F3, wherein the third direction F3 is perpendicular to the first direction F1 and the second direction F2, respectively. Of course, the arrangement direction of the first hole 6201 and the second hole 6202 is parallel to the first direction F1. Thus, on the one hand, the difficulty of processing and manufacturing the mounting member 62 is reduced, and the structure is simple; on the other hand, it conforms to the user's usage habits, improves the user's operating experience, and improves the disassembly efficiency of the plow 50.

[0110] In this embodiment, each second quick release member 65 is movable relative to the coulter 50 along the arrangement direction of the first hole 6201 and the second hole 6202. Thus, the coulter 50 can be switched between the locked state and the unlocked state, which is convenient for user operation and improves the disassembly efficiency of the coulter 50.

[0111] Please also read Figure 6 and Fig.11 , Fig.11 yes Figure 5 Schematic diagram of the structure of the plow 50 and the mounting member 62 in the stirring component 200 in FIG. In some embodiments, each mounting member 62 is provided with a guide structure 621 along the arrangement direction of the first hole 6201 and the second hole 6202, and the connecting portion 51 is provided with a matching guide structure 511 that slidably cooperates with the guide structure 621. Thus, the mounting member 62 and the plow 50 are assembled in alignment, and the assembly efficiency and assembly yield between the plow 50 and the mounting mechanism 60 are improved.

[0112] For example, in this embodiment, one of the guide structure 621 and the guide structure 511 is configured as a T-shaped slide groove, and the other of the guide structure 621 and the guide structure 511 is configured as a T-shaped slider. Thus, based on the sliding fit between the T-shaped slide groove and the T-shaped slider, the plow 50 can be limited and positioned in a certain dimension, thereby improving the stability and reliability of the connection between the plow 50 and the mounting mechanism 60.

[0113] Of course, in some embodiments, one of the guide structure 621 and the guide structure 511 is configured as an L-shaped slide groove, and the other of the guide structure 621 and the guide structure 511 is configured as an L-shaped slider; or, one of the guide structure 621 and the guide structure 511 is configured as a linear slide groove, and the other of the guide structure 621 and the guide structure 511 is configured as a linear slider. The shapes of the guide structure 621 and the guide structure 511 can be set according to actual conditions, and the embodiments of the present application do not specifically limit them.

[0114] For example, in this embodiment, the outer side of the mounting member 62 along the transverse cross section perpendicular to the third direction F3 is H-shaped, thereby reducing the assembly requirements of the mounting member 62 and the plow 50 and facilitating the processing and forming of the mounting member 62. The mounting member 62 is provided with two guide slide structures 621. Thus, any one of the guide slide structures 621 of the mounting member 62 can be slidably assembled with the matching guide structure 511 of the connecting portion 51 of the plow 50, thereby improving the assembly efficiency and assembly yield.

[0115] In some embodiments, the guide structure 621 and the quick-release hole 620 are arranged on different side walls of the mounting member 62. Thus, on the one hand, the problem of interference between the mounting member 62, the plow 50 and the second connecting member during the assembly process is avoided, and the reliability and smoothness of the assembly are improved; on the other hand, the overall structural strength of the mounting member 62 is improved, and the service life is extended. Of course, in one embodiment, the guide structure 621 and the quick-release hole 620 are arranged on the same side wall of the mounting member 62.

[0116] Please also read Figure 6 , Figure 8 and Fig.12 , Fig.12 yes Figure 5 A cross-sectional view of the stirring component 200 along BB. In some embodiments, the mounting mechanism 60 includes a plurality of quick-release components 63. The plurality of quick-release components 63 are arranged at intervals along the third direction F3, and the third direction F3 is perpendicular to the first direction F1 and the second direction F2. Thus, by providing a plurality of sets of quick-release components 63, the stability and reliability of the connection between the plow 50 and the mounting member 62 are improved, the plow 50 is prevented from being loosened, and the safety of the plow 50 stirring device is improved.

[0117] Exemplarily, the mounting mechanism 60 includes two quick-release assemblies 63. The two quick-release assemblies 63 are independently arranged. It should be noted that the number of the quick-release assemblies 63 can be set according to factors such as the specifications of the drying cylinder 11, and the embodiment of the present application does not specifically limit it.

[0118] When the plow 50 is installed on the connecting seat 70, the guide structure 621 of the mounting member 62 is inserted into the guide structure 511 of the connecting portion 51, and then the limiting structure 622 of the mounting member 62 is inserted into the limiting groove 702 of the connecting seat 70, so as to realize the pre-assembly of the plow 50 with the connecting seat 70 and the rotating shaft 20. Then, the first quick release member 64 is sequentially inserted into the first through hole 703 and the first connecting hole 5101, and then all the second quick release members 65 are sequentially inserted into the second through hole 704, the second hole 6202, the second connecting hole 5102 and the slot 6401. The mounting member 62 is moved toward the side close to the rotating shaft 20 by the disassembly tool so that the second connecting section 652 of the second quick release member 65 is aligned with the first hole 6201. At this time, the first quick-release part 64 is locked in the first through hole 703 and the first connecting hole 5101 through the second quick-release part 65, and the second quick-release part 65 is locked in the second through hole 704, the first hole 6201 of the quick-release hole 620 and the second connecting hole 5102 through the first quick-release part 64 and the mounting part 62, so that the plow 50 is in a locked state, thereby achieving fixed installation of the plow 50 on the connecting seat 70 fixedly connected to the rotating shaft 20.

[0119] When the plow 50 is disassembled from the connection seat 70, the mounting member 62 is moved toward the side away from the rotating shaft 20 by the disassembly tool so that the second connection section 652 of the second quick release member 65 is aligned with the second hole 6202. At this time, the second quick release member 65 is removably inserted into the second through hole 704, the second hole 6202, the second connection hole 5102 and the slot 6401, so that the plow 50 is in a locked state. All the second quick release members 65 are pulled out from the slot 6401 of the first quick release member 64, and then the first quick release member 64 is pulled out from the first through hole 703 and the first connection hole 5101, so that the plow 50 is disassembled from the connection seat 70.

[0120] Please also read Fig.13 and Fig.14 , Fig.13 yes Figure 1 A schematic diagram of a local structure of the drying device 1000; Fig.14 yes Fig.13 In the examples of the present application, for a clearer description, Fig.13 For reference, in this application, the X-axis direction is defined as the axial direction of the rotating shaft 20, and the Y-axis direction is defined as the radial direction of the rotating shaft 20. The axial direction X of the rotating shaft 20 is parallel to the extension direction of the central axis of the rotating shaft 20. The axial direction X of the rotating shaft 20 is perpendicular to the radial direction Y.

[0121] The drying device 1000 includes a drying cylinder 11, a rotating shaft 20, a first sealing structure 31 and a heat-insulating structure 32. A drying chamber 1101 and a mounting hole 1106 connected to the drying chamber 1101 are provided in the drying cylinder 11. The drying chamber 1101 is used to accommodate the material to be dried. The rotating shaft 20 is rotatably arranged in the mounting hole 1106. A stirring blade 40 may be provided on the rotating shaft 20, and when the rotating shaft 20 rotates, the stirring blade 40 turns the material to be dried. The first sealing structure 31 is sleeved on the rotating shaft 20 and is located between the inner wall of the mounting hole 1106 and the rotating shaft 20. The first sealing structure 31 is used to seal the rotating shaft 20 and the mounting hole 1106 to prevent the material to be dried from leaking from the mounting hole 1106. The heat-insulating structure 32 is arranged on the side of the first sealing structure 31 away from the rotating shaft 20 and is located outside the drying cylinder 11. The heat insulation structure 32 can block the heat emitted by the drying cylinder 11 and reduce the heat conducted from the drying cylinder 11 to the first sealing structure 31, thereby avoiding heat damage and failure of the first sealing structure 31, increasing the service life of the first sealing structure 31 and improving the reliability of the drying equipment 1000.

[0122] The rotating shaft 20 and the first sealing structure 31 may be connected in an airtight manner. When the drying device 1000 is working, air may be blown into the gap between the rotating shaft 20 and the first sealing structure 31 to prevent the material to be dried from entering the gap between the rotating shaft 20 and the first sealing structure 31, thereby preventing material leakage.

[0123] The side wall of the first sealing structure 31 facing the rotating shaft 20 is provided with a spiral groove 3111, and / or the side wall of the rotating shaft 20 facing the first sealing structure 31 is provided with a spiral groove 3111. When the rotating shaft 20 rotates, the material entering the spiral groove 3111 will move along the spiral groove 3111 toward the drying chamber 110 due to the relative rotation and extrusion of the rotating shaft 20 and the first sealing structure 31, so that the material is pushed back into the drying chamber 1101 to prevent material leakage. In some embodiments, when the rotating shaft 20 rotates relative to the first sealing structure 31, the gas near the rotating shaft 20 is driven by the rotating shaft 20 to form an airflow in the spiral groove 3111 that flows toward the drying chamber 1101. The blowing effect of the airflow can effectively prevent the material from entering the spiral groove 3111, and even if the material enters the spiral groove 3111, the airflow can blow the material back into the drying chamber 1101, thereby effectively preventing the material from leaking.

[0124] Exemplarily, in this embodiment, a spiral groove 3111 is provided on the side wall of the first sealing structure 31 facing the rotating shaft 20. The spiral direction of the spiral groove 3111 is the same as the rotation direction of the rotating shaft 20. Along the axial direction X of the rotating shaft 20, viewed from the side of the drying cylinder 11 close to the first sealing structure 31 toward the direction of the drying chamber 1101, when the rotating shaft 20 rotates in the counterclockwise direction, the spiral direction of the spiral groove 3111 is set to the left-hand direction. Along the axial direction X of the rotating shaft 20, viewed from the side of the drying cylinder 11 close to the first sealing structure 31 toward the direction of the drying chamber 1101, when the rotating shaft 20 rotates in the clockwise direction, the spiral direction of the spiral groove 3111 is set to the right-hand direction.

[0125] In some embodiments, a spiral groove 3111 is provided on the side wall of the rotating shaft 20 facing the first sealing structure 31. The spiral direction of the spiral groove 3111 is opposite to the rotation direction of the rotating shaft 20. Along the axial direction X of the rotating shaft 20, viewed from the side of the drying cylinder 11 close to the first sealing structure 31 toward the drying chamber 1101, when the rotating shaft 20 rotates in the counterclockwise direction, the spiral direction of the spiral groove 3111 is set to the right-hand direction. Along the axial direction X of the rotating shaft 20, viewed from the side of the drying cylinder 11 close to the first sealing structure 31 toward the drying chamber 1101, when the rotating shaft 20 rotates in the clockwise direction, the spiral direction of the spiral groove 3111 is set to the left-hand direction. Among them, when the rotating shaft 20 rotates relative to the first sealing structure 31, the material entering the spiral groove 3111 will be thrown back into the drying chamber 1101 under the action of inertia because the movement speed is lower than that of the rotating shaft 20, thereby effectively avoiding material leakage. In some embodiments, a spiral groove 3111 is provided on the side wall of the first sealing structure 31 facing the rotating shaft 20, and a spiral groove 3111 is provided on the side wall of the rotating shaft 20 facing the first sealing structure 31, the spiral direction of the spiral groove 3111 in the first sealing structure 31 is the same as the rotation direction of the rotating shaft 20, and the spiral direction of the spiral groove 3111 in the rotating shaft 20 is opposite to the rotation direction of the rotating shaft 20.
