[0044] The following description provides preferred embodiments for carrying out this application; however, this description is for the purpose of illustrating the general principles of this application and is not intended to limit the scope of this application. The scope of protection of this application shall be determined by the appended claims.

[0045] Please see Figure 1 , Figure 1 This is an exploded view of the drying apparatus 1000 provided in an embodiment of this application. The drying apparatus 1000 includes a heating element 100 and a stirring element 200. The stirring element 200 is rotatably connected to the heating element 100. The heating element 100 is used to dry the material, and the stirring element 200 is used to stir the material. Thus, the stirring element 200 can evenly distribute the material to be dried inside the drying apparatus 1000, thereby enabling deep drying of the material.

[0046] It should be noted that, Figure 1 The purpose is merely to schematically describe the arrangement between the heating element 100 and the stirring element 200, and is not to specifically limit the connection position, connection relationship and specific structure of each element. Figure 1 The structure of the drying equipment 1000 illustrated in this embodiment is merely a schematic diagram and does not constitute a specific limitation on the drying equipment 1000. In other embodiments of this application, the drying equipment 1000 may include... Figure 1 The device may include more or fewer components, or combinations of certain components, or different components, such as the drying device 1000, and may also include, but is not limited to, dust removal equipment. The dust removal equipment can be used to remove fine powder generated during the heating process of the material to be heated, preventing the fine powder in the material from affecting the lifespan of the battery product.

[0047] Please refer to the following: Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of the heating component 100 of the drying equipment 1000 provided in this application embodiment. The heating component 100 includes a drying cylinder 11 and at least two electromagnetic heating elements 13. A drying chamber 1101 is provided inside the drying cylinder 11, and the drying cylinder 11 is configured with a magnetically conductive structure. The at least two electromagnetic heating elements 13 are laid flat on the outside of the drying chamber 1101 and can be independently assembled and disassembled from the drying cylinder 11. The at least two electromagnetic heating elements 13 operate independently and are used to generate a magnetic field to heat the drying cylinder 11 when energized.

[0048] The drying equipment 1000 provided in this application, on the one hand, is based on the fact that at least two electromagnetic heating elements 13 are laid flat on the outside of the drying chamber 1101 and can be independently assembled and disassembled from the drying cylinder 11, thereby facilitating the assembly, disassembly, and maintenance of the electromagnetic heating elements 13 and the drying cylinder 11, and realizing the modular arrangement of each electromagnetic heating element 13 outside the drying cylinder 11. Therefore, various electromagnetic heating elements 13 can be flexibly combined according to different customer needs, meeting the different needs of different customers, improving product flexibility, and the modular design simplifies the production process, making production more efficient; on the other hand, in the drying chamber 1101 of the drying cylinder 11... At least two electromagnetic heating elements 13 are provided externally, and the drying cylinder 11 is configured with a magnetically conductive structure, so that the electromagnetic heating elements 13 can electromagnetically heat the drying cylinder 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 fact that at least two electromagnetic heating elements 13 can work independently, different electromagnetic heating elements 13 can operate at different frequencies, thereby meeting the requirements of heating materials in different areas of the cylinder at different temperatures, and realizing intelligent control and flexible adjustment of the number of electromagnetic heating elements 13 in operation, achieving effective energy utilization and cost savings.

[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). A magnetically conductive object placed in this field cuts the alternating magnetic field lines, thereby generating an alternating current (i.e., eddy current) inside the object. Eddy currents are caused by the high-speed, random motion of atoms inside the object. The atoms collide and rub against each other, generating heat energy, thus achieving the effect of heating the object. For example, in this embodiment, the drying chamber 1101 contains the material to be dried. 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 fully contact the hot air to complete the drying process. Thus, the drying equipment 1000 achieves the drying of the material by heating and rapidly evaporating moisture.

[0050] Exemplarily, in this embodiment, the drying equipment 1000 is configured as a plowshare drying equipment. The drying cylinder 11 is used to contain the material to be dried. In this embodiment, the material to be dried is battery material. Battery material includes a variety of materials, such as, but not limited to, active materials, conductive agent powders, binder powders, etc. In this embodiment, the drying equipment 1000 is illustrated with battery material. It can be understood that the drying equipment 1000 can also be used to prepare materials such as food, pharmaceuticals, fertilizers, building materials, etc., and the application of the drying equipment 1000 is not limited here. The plowshare drying equipment is a horizontal plowshare drying equipment. Of course, in some embodiments, the plowshare drying equipment can also be a vertical plowshare drying equipment.

[0051] Understandably, due to the large volume of the drying cylinder 11 of the plow-type drying equipment, and the fact that multiple functional units are arranged on the outer wall of the drying cylinder 11 parallel to its axial direction X, the outer wall of the drying cylinder 11 is incomplete. This increases the difficulty of assembling the electromagnetic heating element 13 with the drying cylinder 11, and makes maintenance and replacement of the electromagnetic heating element 13 inconvenient. In this embodiment, by laying at least two electromagnetic heating elements 13 flat on the outside of the drying chamber 1101 and allowing them to be independently assembled and disassembled from the drying cylinder 11, on the one hand, it facilitates the assembly, disassembly, and maintenance of the electromagnetic heating element 13 with the drying cylinder 11; on the other hand, it enables modular arrangement of the various electromagnetic heating elements 13 outside the drying cylinder 11, allowing for flexible combination of various electromagnetic heating elements 13 according to different customer needs, meeting the different requirements of different customers, improving product flexibility, simplifying the production process, and making production more efficient.

[0052] Please refer to it again. Figure 1 and Figure 2The stirring component 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, thereby stirring the material to be dried inside the drying cylinder 11. The stirring blades 40 can evenly distribute the material to be dried inside the drying cylinder 11 within the dryer, thereby enabling deep drying of the material.

[0053] Exemplarily, in this embodiment, the drying cylinder 11 has two mounting holes 1106 at both ends along the axial direction X of the drying cylinder 11. The two ends of the rotating shaft 20 are rotatably mounted within the mounting holes 1106. A plurality of stirring blades 40 are spaced apart along the axial direction X of the rotating shaft 20. At least some of the stirring blades 40 have different mounting directions on the rotating shaft 20. It should be noted that the mounting direction of the stirring blades 40 on the rotating shaft 20 refers to the inclination direction of the plane containing the plow blades of the stirring blades 40 relative to the specific projection plane within a specific projection plane. The specific projection plane is user-defined; for example, the specific projection plane is... Figure 1 The perspective plane in the image, i.e., the specific projection plane, is a projection plane that is parallel to the central axis of the rotating shaft 20 and perpendicular to the feeding direction of the drying equipment 1000.

[0054] The drying equipment 1000 also includes a drive unit. The drive unit is located outside the drying cylinder 11 and is connected to the rotating shaft 20 for transmission. The working principle of the plow dryer is as follows: the material is conveyed into the drying cylinder 11, and the rotating shaft 20 is driven to rotate by the drive unit, so that the stirring blades 40 on the rotating shaft 20 rotate inside the drying cylinder 11. The stirring blades 40 throw the material in the drying cylinder 11 up along the inner wall of the drying cylinder 11, ensuring that the material is in full contact with the inner wall of the drying cylinder 11, increasing the heat-receiving area between the material and the inner wall of the drying cylinder 11, and improving the drying efficiency of the material.

[0055] The top of the drying cylinder 11 is provided with a feed channel 1102 that communicates with 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 and the central axis of the drying cylinder 11 can be perpendicular; or, the central axis of the feed channel 1102 and the central axis of the drying cylinder 11 can also be set at an acute angle. This embodiment of the application does not make specific limitations.

[0056] For example, in this embodiment, the feed channel 1102 is located in the middle of the top wall of the drying cylinder 11 along the axial direction X of the grinding cylinder. Thus, the material to be dried in the drying cylinder 11 moves back and forth from the feed channel 1102 towards both ends of the grinding cylinder along the axial direction X of the grinding cylinder under the stirring action of the stirring member 200, thereby forming two circulation paths within the drying cylinder 11 and 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 located at one end of the top wall of the drying cylinder 11 along the axial direction X of the grinding cylinder. The material to be dried in the drying cylinder 11 moves back and forth from the feed channel 1102 towards the grinding cylinder along the axial direction X of the grinding cylinder under the stirring action of the stirring member 200, thereby forming one circulation path within the drying cylinder 11.

[0057] Please refer to the following: Figure 2 and Figure 3 , Figure 3 yes Figure 1 A schematic diagram of the axial cross-section of the heating element 100 of the drying equipment 1000 is shown. The bottom of the drying cylinder 11 is provided with a discharge channel 1103 connected to the drying chamber 1101, so that the dried material can be quickly discharged from the drying cylinder 11 through the discharge channel 1103 under the action of gravity, improving the material discharge efficiency. 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 and the central axis of the drying cylinder 11 can be perpendicular; or, the central axis of the discharge channel 1103 and the central axis of the drying cylinder 11 can also be at an acute angle. This embodiment does not impose specific limitations.

[0058] For example, in this embodiment, the discharge channel 1103 is located in the middle of the bottom wall of the drying cylinder 11 along the axial direction X of the grinding cylinder. Thus, the dried material inside the drying cylinder 11 moves from both ends of the grinding cylinder along the axial direction X towards 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 located at one end of the bottom wall of the drying cylinder 11 along the axial direction X of the grinding cylinder; this embodiment does not impose specific limitations.

[0059] The drying equipment 1000 also includes a discharge valve 111. The discharge valve 111 is located 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 sealed to the drying cylinder 11 to prevent material leakage.

[0060] In some embodiments, the drying equipment 1000 is further provided with a connecting channel 1104 communicating with the drying chamber 1101. The connecting channel 1104 is used to install dust removal equipment. In some embodiments, the drying equipment 1000 also includes a vacuum pump. The vacuum pump draws a vacuum through the dust removal equipment to separate water vapor from the material. Thus, the installation of the vacuum pump can reduce drying energy consumption and improve drying efficiency. Exemplarily, two connecting channels 1104 are provided. 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 channels 1104 may also be one, three or more, and this application embodiment does not specifically limit the specific number.

[0061] Exemplarily, in this embodiment, the drying cylinder 11 is configured with a cylindrical body, thereby improving the smoothness of the movement of the material to be dried within 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 equipment 1000, and reducing the wear of the drying cylinder 11, thus extending the service life of the drying cylinder 11. 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 is not limited to, a spherical cylinder, a prismatic cylinder, or other regular or irregular cylinders; this application embodiment does not make specific limitations. The radial cross-section of the drying cylinder 11 can also be semi-circular, elliptical, square, polygonal, etc.

[0062] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 2 For reference, "axial direction X" refers to the direction parallel to the central axis of the drying cylinder 11, i.e., 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, i.e., 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, i.e., the direction around the central axis of the drying cylinder 11. 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 presented in the accompanying drawings; this application does not impose specific limitations. For ease 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 implementation.

[0063] In some embodiments, all electromagnetic heating elements 13 operate independently, i.e., all electromagnetic heating elements 13 are connected in parallel, so that each electromagnetic heating element 13 can operate independently without affecting the others. In other embodiments, some electromagnetic heating elements 13 operate independently, while some electromagnetic heating elements 13 operate in conjunction with each other. In other words, some electromagnetic heating elements 13 are connected in parallel, while the remaining electromagnetic heating elements 13 are connected in series. In still other embodiments, all electromagnetic heating elements 13 operate in conjunction with each other.

[0064] Please refer to the following: Figure 1 , Figure 3 and Figure 4 , Figure 4 yes Figure 1 A schematic diagram of the radial cross-section of the heating element 100 of the drying equipment 1000. Exemplarily, in this embodiment, four electromagnetic heating elements 13 are provided. Two of the four electromagnetic heating elements 13 are located on the bottom wall of the drying cylinder 11 and arranged along the axial direction X of the drying cylinder 11. The other two electromagnetic heating elements 13 are located on the front and rear side walls of the drying cylinder 11, respectively. It can be understood that since the top of the drying cylinder 11 is provided with a feeding channel 1102 and a connecting channel 1104, and the bottom of the drying cylinder 11 is provided with a discharging channel 1103, the outer wall of the drying cylinder 11 is not complete. Therefore, this embodiment of the application, by setting electromagnetic heating elements 13 in different areas of the drying cylinder 11, fully utilizes the space of the outer wall of the drying cylinder 11, improving the overall structural compactness of the drying equipment 1000, as well as improving the heating effect and heating efficiency of the drying equipment 1000.

[0065] In some embodiments, two electromagnetic heating elements 13 are provided, both 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; or, one of the two electromagnetic heating elements 13 is located on the bottom wall of the drying cylinder 11, and the other electromagnetic heating element 13 is located on the front or 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 electromagnetic heating element 13 is located on the rear side wall of the drying cylinder 11.

[0066] In some embodiments, three electromagnetic heating elements 13 are provided, 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 the other one of which is located on the front or rear side wall of the drying cylinder 11; or, the three electromagnetic heating elements 13 are located on the bottom wall, front side wall and rear side wall of the drying cylinder 11 respectively.

[0067] The drying equipment 1000 also includes a mounting shell 14. The mounting shell 14 is disposed outside the drying chamber 1101 and forms at least two mounting cavities 120 with the drying cylinder 11. The at least two mounting cavities 120 are independently configured, and each mounting cavity 120 contains at least one electromagnetic heating element 13. Because the at least two mounting cavities 120 are independently configured, the mounting shell 14 can reduce the risk of electromagnetic leakage within each mounting cavity 120 and prevent crosstalk between the electromagnetic heating elements 13 in different mounting cavities 120. This improves the flexibility of controlling the heating temperature of different heating zones and avoids the problem of some electromagnetic heating elements 13 failing and preventing the material from being heated and dried.

[0068] For example, a discharge channel 1103 is provided in the middle of the bottom wall of the drying cylinder 11. The electromagnetic heating element 13 includes two first electromagnetic heating bodies 131. Both first electromagnetic heating bodies 131 are 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 with respect to the discharge channel 1103. The two first electromagnetic heating bodies 131 work together; or, the two first electromagnetic heating bodies 131 work independently. Therefore, on the one hand, by providing two first electromagnetic heating elements 131 on the bottom wall of the drying cylinder 11, the heat exchange time between the material to be dried and the bottom wall of the drying cylinder 11 is increased, and the heating area of ​​the bottom region of the drying cylinder 11 for heating the material to be dried is increased, thereby improving the drying effect and efficiency of the drying equipment 1000. On the other hand, by ensuring the synchronous operation of the two first electromagnetic heating elements 131, the heating uniformity of the bottom region of the drying cylinder 11 is improved, thus enhancing 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 elements 131 are arranged independently so that they work independently without affecting each other, improving the flexibility of heating local areas of the drying cylinder 11 and avoiding the problem of not being able to heat and dry the material due to the failure of one electromagnetic heating element 13.

[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. Both first electromagnetic heating elements 131 are disposed within the first cavity 1201. Thus, the first shell 141 and the two first electromagnetic heating elements 131 are integrated into an integral structure, improving assembly efficiency.

[0070] Of course, in some embodiments, the mounting shell 14 includes two first shells 141. Both first shells 141 are located at the bottom of the drying cylinder 11 and connected to the drying cylinder 11 to form two independently arranged first cavities 1201. Two first electromagnetic heating elements 131 are respectively disposed within the two first cavities 1201. Therefore, by independently arranging the two first cavities 1201 and separately arranging the two first electromagnetic heating elements 131 within the two first cavities 1201, the two first electromagnetic heating elements 131 are isolated from each other within the two first cavities 1201, thereby reducing the risk of electromagnetic leakage within the two first cavities 1201 and preventing crosstalk between the two first electromagnetic heating elements 131. This improves the flexibility of adjusting the heating temperature of different heating zones and avoids the problem of the material being dried being unable to be heated and dried due to the failure of one first electromagnetic heating element 131.

[0071] In some embodiments, the mounting housing 14 includes a second housing 142. The second housing 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 element 132. The second electromagnetic heating element 132 is disposed within the second cavity 1202, wherein the second cavity 1202 is independently disposed from the first cavity 1201; and / or, the mounting housing 14 includes a third housing 143, the third housing 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 element 133, the third electromagnetic heating element 133 is disposed within the third cavity 1203, wherein the third cavity 1203 is independently disposed from the first cavity 1201. Therefore, by independently configuring at least one of the second cavity 1202 and the third cavity 1203 from the first cavity 1201, and by configuring at least one of the second electromagnetic heating element 132 and the third electromagnetic heating element 133 from the first electromagnetic heating element 131 in different mounting cavities 120, the risk of electromagnetic leakage between the second cavity 1202 and the third cavity 1203 and the first cavity 1201 is reduced, and crosstalk between the second electromagnetic heating element 132 and the third electromagnetic heating element 133 and the first electromagnetic heating element 131 is prevented. This improves the flexibility of adjusting the heating temperature of different heating areas and avoids the problem of not being able to heat and dry the material due to the failure of one electromagnetic heating element 13.

[0072] In this embodiment, for example, the first electromagnetic heating element 131, the second electromagnetic heating element 132, and the third electromagnetic heating element 133 operate independently of each other. The first cavity 1201, the second cavity 1202, and the third cavity 1203 are also independently configured in pairs, meaning any two of the first cavity 1201, the second cavity 1202, and the third cavity 1203 are isolated from each other. This prevents crosstalk between the first electromagnetic heating element 131, the second electromagnetic heating element 132, and the third electromagnetic heating element 133, improves the flexibility of adjusting the heating temperature of different heating zones, and avoids the problem of being unable to heat and dry the material due to the failure of one electromagnetic heating element 13.

[0073] In some embodiments, two of the first electromagnetic heating element 131, the second electromagnetic heating element 132, and the third electromagnetic heating element 133 operate independently of each other, thereby improving the flexibility of adjusting the heating temperature of different heating zones and avoiding the problem of being unable to heat and dry the material due to the failure of one electromagnetic heating element 13. For example, the first electromagnetic heating element 131, the second electromagnetic heating element 132, and the third electromagnetic heating element 133 all operate independently of each other; or, any two of the first electromagnetic heating element 131, the second electromagnetic heating element 132, and the third electromagnetic heating element 133 operate independently of each other.

[0074] In some embodiments, the drying equipment 1000 further includes a mounting housing 14. The mounting housing 14 is detachably connected to the drying cylinder 11. At least one mounting housing 14 is provided, and each mounting housing 14 is connected to at least one electromagnetic heating element 13 to form an integral structure. Thus, on the one hand, the detachable connection between the mounting housing 14 and the drying cylinder 11 facilitates assembly, maintenance, replacement, and other operations; on the other hand, the connection between each mounting housing 14 and at least one electromagnetic heating element 13 to form an integral structure improves the integration of the electromagnetic heating element 13 and the mounting housing 14, simplifies the structural setup, and saves space.

[0075] In some embodiments, the mounting housing 14 is configured as a magnetically and thermally shielded structure; and / or, an insulating and heat-insulating layer is provided on the mounting housing 14. Thus, by configuring the mounting base 145 as a magnetically shielded structure, electromagnetic heating of the mounting housing 14 is prevented, and heat conduction to the outside is prevented from scalding the operator, thereby improving the operational safety of the drying equipment 1000; on the other hand, by configuring the mounting housing 14 as a magnetically and thermally shielded structure; or by providing an insulating and heat-insulating layer on the mounting housing 14, heat conduction to the outside can be prevented from scalding the operator.

[0076] In some embodiments, the mounting housing 14 is provided with a mounting groove 1401 with an opening facing the drying cylinder 11. The mounting groove 1401 is used to mount at least two electromagnetic heating elements 13. Therefore, by providing the mounting groove 1401 with an opening facing the drying cylinder 11 on the mounting housing 14, the assembly of the electromagnetic heating elements 13 is facilitated, and the cutting of alternating magnetic lines of force generated by the drying cylinder 11 on the electromagnetic heating elements 13 is improved, thereby enhancing the heating effect of the electromagnetic heating elements 13 on the drying cylinder 11. Exemplarily, in this embodiment, multiple mounting housings 14 are provided, each mounting housing 14 being provided with a mounting groove 1401 for mounting a corresponding electromagnetic heating element 13. In this embodiment, the mounting groove 1401 is configured as an arc-shaped groove, thereby increasing the mounting area of ​​the electromagnetic heating element 13, improving heating uniformity and heating effect, and facilitating the alignment and assembly of the electromagnetic heating element 13, the mounting housing 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 and spiral configuration along the circumferential direction of the drying cylinder 11. Exemplarily, in this embodiment, each electromagnetic heating element 13 is arranged in a curved and spiral configuration within the mounting groove 1401, thereby improving 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 segments 130. The plurality of electromagnetic heating segments 130 are curved and configured to surround the outer contour of the drying cylinder 11. Therefore, on the one hand, the overall shape of the electromagnetic heating element 13 is adapted to 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 fact that the electromagnetic heating element 13 is arranged in a curved and spiraling manner in the mounting groove 1401, and multiple electromagnetic heating segments 130 are arranged to bend around the outer contour of the drying cylinder 11, the radiation area of ​​the electromagnetic heating element 13 on the drying cylinder 11 is increased, the heating effect of the drying cylinder 11 is improved, assembly is facilitated, the uniformity of heating and drying of materials by the drying cylinder 11 is improved, and the quality of the materials is improved.

[0078] Multiple electromagnetic heating sections 130 are equidistant from the outer wall of the drying cylinder 11. 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. Adjacent axial heating sections are connected by the circumferential heating section. This reduces the number of bends in the electromagnetic heating element 13, improves the space utilization of the electromagnetic heating element 13, and facilitates the assembly of the electromagnetic heating element 13. The drying cylinder 11 is configured as a cylindrical structure. The curvature of the electromagnetic heating sections 130 is the same as the curvature 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.

[0079] In this embodiment, for example, at least one mounting base 145 is provided inside the mounting housing 14, and the at least one mounting base 145 is fixedly connected to the mounting housing 14. The mounting base 145 is disposed between the mounting housing 14 and the drying cylinder 11. The electromagnetic heating element 13 is disposed on the mounting base 145. Specifically, the electromagnetic heating element 13 is disposed on the side of the mounting base 145 facing the drying cylinder 11. The mounting base 145 has a mounting groove 1401 on the side facing the drying cylinder 11. The electromagnetic heating element 13 is detachably connected to the mounting base 145; or, the mounting base 145 is detachably connected to the mounting housing 14, thereby facilitating maintenance, replacement, and other operations of the electromagnetic heating element 13, and providing flexibility in use.

[0080] Please refer to it again. Figure 2 In some embodiments, the front or rear sidewall of the drying cylinder 11 is further provided with an observation and operation window 1105 communicating with the drying chamber 1101. The observation and operation window 1105 and at least two electromagnetic heating elements 13 are arranged at intervals along the circumferential direction Z of the drying cylinder 11. Thus, on the one hand, the setting of the observation and operation window 1105 allows the operator to conveniently observe the drying status of the material inside the drying cylinder 11 and to facilitate the maintenance of the stirring blades inside the drying cylinder 11; on the other hand, it prevents the electromagnetic heating elements 13 from being exposed in the observation and operation window 1105, 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 an X-interval along the axial direction of the drying cylinder 11, thereby improving the overall structural strength of the drying cylinder 11 and facilitating the maintenance of the stirring blades inside the drying cylinder 11 by the staff. It should be noted that the number of observation operation windows 1105 can be set according to the actual situation, and this application embodiment does not make a specific limitation. For example, the number of observation operation windows 1105 can also be one, three or more.

[0082] An observation and operation door 112 is provided at the position corresponding to the observation and operation window 1105 on the drying cylinder 11. 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 sealed to the drying cylinder 11, thereby preventing the material inside the drying cylinder 11 from escaping from the observation and operation window 1105, improving the safety and sealing of the drying equipment 1000. The observation and operation door 112 and the drying cylinder 11 are flip-up, which facilitates the user's maintenance operations and improves 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.

[0083] In some embodiments, the drying device 1000 further includes a decorative shell 15. The decorative shell 15 is fixedly connected to the drying cylinder 11 and / or the mounting shell 14. The outer side wall of the decorative shell 15 facing away from the drying cylinder 11 is a first surface 140, and the outer side wall of the mounting shell 14 facing away from the drying cylinder 11 is a second surface 150. The first surface 140 and the second surface 150 are connected to form a complete outer surface 160. Thus, on the one hand, the outer shell of the drying device 1000 forms a complete and regular outer wall, thereby improving the aesthetic appearance of the drying device 1000 and avoiding the risk of collision due to an irregular outer wall in a confined space, or avoiding installation difficulties caused by an irregular outer wall; on the other hand, it reduces electromagnetic leakage and improves the safety of the drying device 1000. The decorative shell 15 is disposed on the top of the drying cylinder 11 and is laid flat on the outer side wall of the drying cylinder 11 along with all the mounting shells 14.

[0084] In this embodiment, the outer wall of the decorative shell 15 facing away from the drying cylinder 11 includes a first decorative surface 151, a second decorative surface 152, and a third decorative surface 153. The first decorative surface 151 connects the second decorative surface 152 and the third decorative surface 153. The first decorative surface 151 is parallel to the horizontal plane, which is perpendicular to the height direction of the drying equipment 1000, thereby improving the stability and sturdiness of supporting the dust removal equipment. The second decorative surface 152 and the third decorative surface 153 are both inclined downward relative to the first decorative surface 151 towards the side closer to the drying cylinder 11. The observation window 1105 is located on at least one of the second decorative surface 152 and the third decorative surface 153. On the one hand, this increases the user's field of vision for observing the interior of the drying cylinder 11 and aligns with user observation habits. On the other hand, it avoids the accumulation of impurities and foreign objects on the second decorative surface 152 and the third decorative surface 153 of the decorative shell 15, reducing the risk of impurities and foreign objects entering the drying cylinder 11 through the observation window 1105 and contaminating the material. Furthermore, the outer wall of the decorative shell 15 is prismatic, facilitating the alignment and assembly of the decorative shell 15 with the mounting shell 14, improving assembly efficiency and yield. Of course, in some embodiments, the first decorative surface 151, the second decorative surface 152, and the third decorative surface 153 are connected to form a continuous arc surface, thereby preventing the decorative shell 15 from scratching.

[0085] Please refer to the following: Figure 5 , Figure 6 and Figure 7 , Figure 5 yes Figure 1 A schematic diagram of the stirring component 200 of the drying equipment 1000. Figure 6 yes Figure 5 A cross-sectional view of the stirring component 200 along AA; Figure 7 yes Figure 5 A schematic diagram of the mounting mechanism 60 of the stirring component 200 is shown. Each stirring blade 40 includes a plow blade 50 and a mounting mechanism 60. The plow blade 50 is detachably fixed to the rotating shaft 20 via the mounting mechanism 60. Therefore, by detachably fixing the plow blade 50 to the mounting mechanism 60, it is convenient to assemble, maintain, replace, or clean the plow blade 50. Of course, in some embodiments, some stirring blades 40 include both the plow blade 50 and the mounting mechanism 60; that is, some plow blades 50 are detachably fixed to the rotating shaft 20 via the mounting mechanism 60, while the remaining plow blades 50 are non-detachably fixed to the rotating shaft 20.

[0086] Specifically, the rotating shaft 20 is used to drive the plow blade 50 to rotate. Specifically, the rotating shaft 20 is fixedly connected to the mounting mechanism 60, and the plow blade 50 is detachably fixedly connected to the rotating shaft 20 through the mounting mechanism 60, so that the plow blade 50 rotates with the rotation of the rotating shaft 20, thereby realizing the plow blade 50 stirring the material in the drying cylinder 11.

[0087] For example, in this embodiment, both the plow blades 50 and the mounting mechanisms 60 are provided in multiples. Each plow blade 50 corresponds one-to-one with a corresponding mounting mechanism 60. The multiple plow blades 50 are spaced apart along the axial direction of the rotating shaft 20. Each plow blade 50 is detachably fixedly connected to its corresponding mounting mechanism 60. Of course, in some embodiments, the number of mounting mechanisms 60 is less than the number of plow blades 50, and at least some of the mounting mechanisms 60 are detachably fixedly connected to multiple plow blades 50.

[0088] The mounting mechanism 60 is used to mount the plow blade 50. The plow blade 50 has a locked state and an unlocked state. The mounting mechanism 60 includes two mounting members 62 and at least one quick-release assembly 63. Each quick-release assembly 63 includes a first quick-release member 64 and two second quick-release members 65. The first quick-release member 64 is movably inserted into the plow blade 50 along a first direction F1. The two mounting members 62 are respectively mounted on two side walls of the plow blade 50 along a second direction F2. The second direction F2 intersects with the first direction F1; each second quick-release member 65 is movably inserted into the corresponding mounting member 62 and the plow blade 50 along the second direction F2, and is used to engage or disengage from the first quick-release member 64. When the plow blade 50 is in the locked state, each first quick-release piece 64 engages with the corresponding second quick-release piece 65 to lock the plow blade 50 onto the mounting piece 62; when the plow blade 50 is in the unlocked state, each first quick-release piece 64 disengages from the corresponding second quick-release piece 65 to unlock the plow blade 50 locked onto the mounting piece 62.

[0089] The installation mechanism 60 provided in this application, on the one hand, is based on the first quick-release component 64 and the second quick-release component 65 respectively provided in the first direction F1 and the second direction F2, thereby realizing the fixed connection between the plow blade 50 and the installation component 62 in multiple spatial dimensions, thus preventing the plow blade 50 from loosening and falling off during operation and improving the mixing effect of the plow blade 50; on the other hand, it realizes the quick-release connection between the plow blade 50 and the installation component 62, thereby avoiding the problem of screw loss due to negligence during installation or replacement, which is often caused by screw installation, thereby reducing labor costs, facilitating assembly, disassembly, replacement and maintenance, making it flexible to use and improving production efficiency.

[0090] In this application embodiment, the term "quick-release" refers to the ability to quickly disassemble or detach two connected or associated components / elements; and the connection method between two components / elements connected in a quick-disassembly / rapid-detachment manner is called a "quick-release connection." Specifically, quick-release can refer to the ability of the plow blade 50 and the mounting component 62 to be quickly disassembled or assembled using the provided quick-release assembly 63. Correspondingly, the connection method using quick-release is also called a quick-release connection. The first quick-release component 64 and the second quick-release component 65 refer to the structure for modularizing the various parts of the plow blade 50 and the mounting component 62, thereby enabling the quick disassembly of the plow blade 50 and the mounting component 62.

[0091] Exemplarily, the plow blade 50 includes a connecting portion 51 and a stirring portion 52 connected to the connecting portion 51. The connecting portion 51 is provided with a first connecting hole 5101 and at least two second connecting holes 5102. The first connecting hole 5101 communicates with the at least two second connecting holes 5102. 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 blade 50 is in the locked state, each second quick-release member 65 engages with the slot 6401 and is locked in the corresponding quick-release hole 620 and second connecting hole 5102, and each first quick-release member 64 is locked in the first connecting hole 5101. When the plow blade 50 is in the unlocked state, each second quick-release member 65 disengages from the slot 6401 and is removably inserted into the corresponding quick-release hole 620 and second connecting hole 5102, and each first quick-release member 64 is removably inserted into the first connecting hole 5101. Therefore, on the one hand, the slot 6401 of the first quick-release component 64 defines two first quick-release components 64, realizing the mutual cooperation and snapping of the first quick-release components 64 and the second quick-release component 65 to achieve the purpose of fixing and locking the plow blade 50 and the mounting component 62. This improves the stability and reliability of the connection between the plow blade 50 and the mounting component 62, avoids the problem of the plow blade 50 and the mounting component 62 becoming loose during the material drying process, reduces labor costs, facilitates assembly, disassembly, replacement and maintenance, is flexible in use, and improves production efficiency. On the other hand, the mutual cooperation and snapping of the first quick-release component 64 and the second quick-release component 65 makes the structure of the mounting mechanism 60 simple and compact, saves the space occupied by the mounting mechanism 60, and improves the efficiency and flexibility of the mounting mechanism 60.

[0092] For example, in this embodiment, the number of first connecting holes 5101 is the same as the number of first quick-release members 64, and they are arranged in a one-to-one correspondence. The number of quick-release holes 620 and the number of second connecting holes 5102 are the same as the number of second quick-release members 65, and they are arranged in a one-to-one correspondence. Of course, in some embodiments, the number of first connecting holes 5101 is greater than the number of first quick-release members 64, and the number of second connecting holes 5102 is greater than the number of second quick-release members 65. That is, the first quick-release members 64 and the second quick-release members 65 can be connected to the corresponding first connecting holes 5101 and second connecting holes 5102, respectively.

[0093] In some embodiments, the mounting mechanism 60 further includes a connecting seat 70. The connecting seat 70 is used for fixed connection with the rotating shaft 20. Exemplarily, in this embodiment, the connecting seat 70 and the rotating shaft 20 are integrally formed, thereby improving the connection strength and reliability between the connecting seat 70 and the rotating shaft 20, as well as improving the assembly and disassembly efficiency of the connecting seat 70 and the rotating shaft 20. Of course, in some embodiments, the connecting seat 70 and the rotating shaft 20 can also be detachably fixedly connected, thereby facilitating maintenance, replacement, and cleaning of the connecting seat 70 and the rotating shaft 20. The connecting seat 70 and the rotating shaft 20 can be fixedly connected by locking structures such as screws and clips, which are not specifically limited in this application embodiment.

[0094] The connecting seat 70 is provided with a receiving groove 701. The connecting portion 51 of the plow blade 50 is disposed within the receiving groove 701. At least a portion of the structure of the two mounting members 62 is mounted within 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 this embodiment, the connecting portion 51 of the plow blade 50 and the two mounting members 62 are pluggably mounted within the receiving groove 701, thereby facilitating the alignment and assembly of the connecting seat 70 with the plow blade 50 and the two mounting members 62. Specifically, the connecting seat 70 is provided with two limiting grooves 702 communicating with the receiving groove 701 on its two sidewalls along the second direction F2. Each mounting member 62 is provided with a limiting structure 622 that slides with the limiting groove 702.

[0095] For example, in this embodiment, the connecting base 70 and the two mounting members 62 are independently arranged and detachably fixedly connected. This facilitates the removal of the mounting members 62 and the plow blade 50 from the connecting base 70, improving the efficiency of the plow blade 50's assembly and disassembly.

[0096] In some embodiments, each mounting member 62 has a disassembly / reassembly structure 6203 at its end away from the rotating shaft 20. The disassembly / reassembly structure 6203 is used to install disassembly / reassembly tools. Thus, by connecting the disassembly / reassembly tool to the mounting member 62, it is easier to disassemble / reassemble the mounting member 62 and the plow blade 50 to the connecting seat 70, improving the user experience. The disassembly / reassembly tool can be, but is not limited to, a screwdriver, pliers, or a socket wrench. Exemplarily, in this embodiment, the disassembly / reassembly structure 6203 is configured as a groove structure, such as a threaded hole, and the disassembly / reassembly tool is a screwdriver that mates with the threaded hole. Of course, in some embodiments, the disassembly / reassembly structure 6203 can also be configured as a protruding structure to prevent material residue from remaining on the disassembly / reassembly structure 6203. The disassembly / reassembly structure 6203 can be configured according to actual conditions, and this application embodiment does not impose specific limitations.

[0097] For example, in this embodiment, the limiting groove 702 is configured as a T-shaped groove, and the limiting structure 622 is configured as a T-shaped slider. Therefore, based on the sliding cooperation of the T-shaped groove and the T-shaped slider, the connecting seat 70 can be limited and positioned in a certain dimension, improving the stability and reliability of the connection between the plow blade 50 and the mounting member 62. Of course, in some embodiments, the limiting groove 702 is configured as an L-shaped groove or a straight 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; this embodiment does not impose specific limitations.

[0098] The connecting seat 70 has a first through hole 703 at the position corresponding to the first connecting hole 5101. The connecting seat 70 has a second through hole 704 at the position corresponding to the second connecting hole 5102. When the plow blade 50 is in the locked state, the first quick-release piece 64 is sequentially inserted and locked in the first through hole 703 and the first connecting hole 5101, and the second quick-release piece 65 is sequentially inserted and locked in the second through hole 704, the quick-release hole 620, the second connecting hole 5102, and the slot 6401. When the plow blade 50 is in the unlocked state, the first quick-release piece 64 is removably inserted in the first through hole 703 and the first connecting hole 5101, and the second quick-release piece 65 is removably inserted in the second through hole 704, the quick-release hole 620, the second connecting hole 5102, and the slot 6401.

[0099] Please refer to it again. Figure 6 , Figure 7 and Figure 8 , Figure 8 yes Figure 5The diagram shows the structure of the first quick-release member 64 and the second quick-release member 65 of the plow-type stirring component 200. In this embodiment, the slot 6401 is an annular slot, which facilitates the processing and forming of the first quick-release member 64 and reduces the installation requirements of the first quick-release member 64. Of course, in some embodiments, the slot 6401 can also be, but is not limited to, an arc slot, a circular slot, a square slot, etc., and this application embodiment does not make specific limitations. When the second quick-release member 65 is inserted into the slot 6401, the second quick-release member 65 is locked onto 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 pin. Of course, in some embodiments, at least one of the first quick-release member 64 and the second quick-release member 65 may also be configured as a screw or bolt. Exemplarily, both the first quick-release member 64 and the second quick-release member 65 include a shaft 641 and a head 642 connected to one end of the shaft 641. A slot 6401 is provided at the end of the shaft 641 of the first quick-release member 64 away from the head 642.

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

[0102] In some embodiments, the slot 6401 includes a first slot and a second slot communicating with the first slot, wherein the extending directions of the first slot and the second slot are different. For example, the slot 6401 can also be configured as T-shaped or L-shaped. A locking block is provided at the end of the second quick-release member 65, and the locking block cooperates with the slot 6401. When the locking block of the second quick-release member 65 rotates into the first and second slots, the second quick-release member 65 is fixedly engaged with the first quick-release member 64. When the locking block of the second quick-release member 65 rotates into the first slot, the second quick-release member 65 can disengage from the fixed engagement with the first quick-release member 64.

[0103] In some embodiments, the mounting mechanism 60 further includes a gasket 66. The gasket 66 is fitted onto the shaft 641 and blocks the shaft head 642. Thus, on the one hand, the gasket 66 can provide a good sealing effect, preventing material from entering the gap between the first quick-release member 64 and the second quick-release member 65 and the connection 51 between the mounting member 62 and the plow blade 50, reducing wear and material loss, and facilitating disassembly and assembly; on the other hand, the gasket 66 can absorb some vibration energy, reducing the impact between parts, thereby reducing the wear of the stirring component 200 and extending the service life of the stirring component 200; furthermore, the gasket 66 can evenly distribute the pressure generated by the first quick-release member 64 and the second quick-release member 65, preventing the first quick-release member 64 and the second quick-release member 65 from deforming or being damaged due to excessive local pressure during installation.

[0104] Please refer to it again. Figure 5 and Figure 9 , Figure 9 yes Figure 5 The diagram shows the structure of the mounting mechanism 60 and the plow blade 50 of the mixing component 200. A guide surface 5103 is provided at the end of the connecting part 51 near the rotating shaft 20. The shape of the guide surface 5103 matches the shape of the rotating shaft 20, thereby preventing the plow blade 50 from shaking with the rotating shaft 20 during material mixing, reducing noise, and improving the service life of both the plow blade 50 and the rotating shaft 20.

[0105] In some embodiments, the plow blade 50 further includes a support portion 53 connected between the connecting portion 51 and the stirring portion 52. Thus, the support portion 53 can support and fix the stirring portion 52, facilitating adjustment of the distance between the plow blade 50 and the drying cylinder 11. The stirring portion 52 of the plow blade 50 has a rounded corner structure 521 at its edge, effectively preventing the stirring component 200 from damaging the material due to high-speed rotation, thus preventing the formation of fine powder and avoiding the impact of fine powder on battery life.

[0106] Please refer to the following: Figure 6 , Figure 8 and Figure 10 , Figure 10 yes Figure 5A side view of the mounting member 62 of the stirring component 200. 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 communicating with 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 inserted into the first hole 6201. The second connecting section 652 is removably inserted into the second hole 6202. When the plow blade 50 is in the 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 blade 50 is in the unlocked state, each second quick-release member 65 is removably inserted into the second hole 6202, the second connecting hole 5102, and the slot 6401. Understandably, when the second connecting segment 652 is aligned with the second hole 6202, the second quick-release piece 65 can be pulled out sequentially from the slot 6401, the second connecting hole 5102, and the second hole 6202, so that the plow blade 50 enters the unlocked state; when the second connecting segment 652 is aligned with the first hole 6201, the second quick-release piece 65 is located outside the quick-release hole 620 and is stopped at the position of the mounting piece 62 corresponding to the first hole 6201, that is, the second quick-release piece 65 cannot be pulled out from the slot 6401, the second connecting hole 5102, and the second hole 6202, so that the plow blade 50 enters the locked state. Therefore, by setting the second quick-release piece 65 as a first connecting segment 651 and a second connecting segment 652 with different radial dimensions, and setting the quick-release hole 620 as a first hole 6201 and a second hole 6202 with different hole diameters, when disassembling the plow blade 50, the user can move the mounting piece 62 so that the second connecting segment 652 of the second quick-release piece 65 is aligned with the second hole 6202, thereby enabling the user to pull the second quick-release piece 65 out of the slot 6401, the second connecting hole 5102 and the second hole 6202, which facilitates the user's disassembly of the plow blade 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 connecting section 651 and a second connecting section 652. The first connecting section 651 connects the second connecting section 652 and the shaft head 642. In some embodiments, the shaft head 642 of the second quick-release member 65 is located outside the quick-release hole 620, thereby providing the shaft head 642 with a gripping and operating function for the user, facilitating the user to pull out the second quick-release member 65 and improving the disassembly efficiency of the plow blade 50.

[0108] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 6 and Figure 7 For reference, "first direction F1" refers to the direction parallel to the insertion direction of the first quick-release piece 64, that is... Figure 6The left and right directions; the term "second direction F2" refers to the direction parallel to the insertion direction of the second quick-release piece 65, that is... Figure 6 The vertical direction; 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 drying cylinder 11 is defined by three orthogonal directions: the first direction F1, the second direction F2, and the third direction F3. 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 viewing angle presented in the accompanying drawings; this application does not impose specific limitations. For ease of description, the directions "up," "down," "left," "right," "front," and "back" in this application are relative positions and do not constitute a limitation on 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 second direction F2. Therefore, on the one hand, the manufacturing difficulty of the mounting part 62 is reduced, resulting in a simple structure; on the other hand, it conforms to user habits, improves the user's operating experience, and increases the disassembly efficiency of the plow blade 50.

[0110] In this embodiment, each second quick-release component 65 is movable relative to the plow blade 50 along the arrangement direction of the first hole 6201 and the second hole 6202. This allows the plow blade 50 to switch between a locked and unlocked state, facilitating user operation and improving the disassembly efficiency of the plow blade 50.

[0111] Please refer to the following: Figure 6 and Figure 11 , Figure 11 yes Figure 5 The diagram shows the structure of the plow blade 50 and the mounting member 62 in the stirring component 200. 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 part 51 is provided with a matching guide structure 511 that slides with the guide structure 621. This achieves the alignment and assembly of the mounting member 62 and the plow blade 50, improving the assembly efficiency and yield between the plow blade 50 and the mounting mechanism 60.

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

[0113] Of course, in some embodiments, one of the guide structure 621 and the matching guide structure 511 is configured as an L-shaped groove, and the other of the guide structure 621 and the matching guide structure 511 is configured as an L-shaped slider; or, one of the guide structure 621 and the matching guide structure 511 is configured as a straight groove, and the other of the guide structure 621 and the matching guide structure 511 is configured as a straight slider. The shape of the guide structure 621 and the matching guide structure 511 can be set according to the actual situation, and the embodiments of this application do not make specific limitations.

[0114] For example, in this embodiment, the outer side of the transverse section of the mounting member 62 perpendicular to the third direction F3 is H-shaped, thereby reducing the assembly requirements between the mounting member 62 and the plow blade 50 and facilitating the processing and forming of the mounting member 62. The mounting member 62 is provided with two guide sliding structures 621. Thus, either guide sliding structure 621 of the mounting member 62 can slide to assemble with the guide structure 511 of the connection part 51 of the plow blade 50, improving assembly efficiency and assembly yield.

[0115] In some embodiments, the guide slide structure 621 and the quick-release hole 620 are disposed on different sidewalls of the mounting member 62. This avoids interference between the mounting member 62, the plow blade 50, and the second connector during assembly, improving assembly reliability and smoothness; it also enhances the overall structural strength of the mounting member 62 and extends its service life. Of course, in one embodiment, the guide slide structure 621 and the quick-release hole 620 are disposed on the same sidewall of the mounting member 62.

[0116] Please refer to the following: Figure 6 , Figure 8 and Figure 12 , Figure 12 yes Figure 5 The mixing component 200 is shown in a cross-sectional view 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 a third direction F3, which is perpendicular to the first direction F1 and the second direction F2, respectively. Thus, by providing multiple sets of quick-release components 63, the stability and reliability of the connection between the plow blade 50 and the mounting component 62 are improved, preventing the plow blade 50 from becoming loose and improving the safety of the plow blade 50 mixing device.

[0117] For example, the mounting mechanism 60 includes two quick-release components 63. The two quick-release components 63 are arranged independently of each other. It should be noted that the number of quick-release components 63 can be set according to factors such as the specifications of the drying cylinder 11, and this embodiment does not impose a specific limitation.

[0118] When the plow blade 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 part 51, and then the limiting structure 622 of the mounting member 62 is inserted into the limiting groove 702 of the connecting seat 70, thereby realizing the pre-assembly of the plow blade 50 with the connecting seat 70 and the rotating shaft 20. Then, the first quick-release piece 64 is sequentially inserted into the first through hole 703 and the first connecting hole 5101, and then all the second quick-release pieces 65 are sequentially inserted into the second through hole 704, the second hole 6202, the second connecting hole 5102 and the slot 6401. Using a disassembly and assembly tool, the mounting member 62 is moved towards the side closer to the rotating shaft 20 so that the second connecting section 652 of the second quick-release piece 65 is aligned with the first hole 6201. At this time, the first quick-release piece 64 is locked in the first through hole 703 and the first connecting hole 5101 by the second quick-release piece 65, and the second quick-release piece 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 by the first quick-release piece 64 and the mounting piece 62, so that the plow blade 50 is in a locked state, thereby realizing that the plow blade 50 is fixedly installed on the connecting seat 70 fixedly connected to the rotating shaft 20.

[0119] When the plow blade 50 is removed from the connecting seat 70, the mounting piece 62 is moved away from the rotating shaft 20 using a disassembly tool, so that the second connecting section 652 of the second quick-release piece 65 is aligned with the second hole 6202. At this time, the second quick-release piece 65 is detachably inserted into the second through hole 704, the second hole 6202, the second connecting hole 5102, and the slot 6401, so that the plow blade 50 is in a locked state. All the second quick-release pieces 65 are pulled out from the slot 6401 of the first quick-release piece 64, and then the first quick-release piece 64 is pulled out from the first through hole 703 and the first connecting hole 5101, thereby realizing the removal of the plow blade 50 from the connecting seat 70.

[0120] Please refer to the following: Figure 13 and Figure 14 , Figure 13 yes Figure 1 A partial structural schematic diagram of the drying equipment 1000 in the diagram; Figure 14 yes Figure 13 An enlarged view of part I in this application. In the embodiments of this application, for clearer description, [the following is used]... Figure 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 equipment 1000 includes a drying cylinder 11, a rotating shaft 20, a first sealing structure 31, and a heat insulation structure 32. The drying cylinder 11 has a drying chamber 1101 and a mounting hole 1106 communicating with the drying chamber 1101. The drying chamber 1101 is used to hold the material to be dried. The rotating shaft 20 is rotatably inserted into the mounting hole 1106. A stirring blade 40 may be installed on the rotating shaft 20; when the rotating shaft 20 rotates, the stirring blade 40 agitates the material to be dried. The first sealing structure 31 is sleeved on the rotating shaft 20 and located between the inner wall of the mounting hole 1106 and the rotating shaft 20. The first sealing structure 31 seals the rotating shaft 20 and the mounting hole 1106, preventing leakage of the material to be dried from the mounting hole 1106. The heat insulation structure 32 is located on the side of the first sealing structure 31 facing 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, reduce the heat conducted from the drying cylinder 11 to the first sealing structure 31, thereby preventing the first sealing structure 31 from being damaged or failing due to heat, improving 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 can be connected in an airtight manner. When the drying equipment 1000 is working, blowing air into the gap between the rotating shaft 20 and the first sealing structure 31 can prevent the material to be dried from entering the gap between the rotating shaft 20 and the first sealing structure 31, thus preventing material leakage.

[0123] The first sealing structure 31 has a spiral groove 3111 on its sidewall facing the rotating shaft 20, and / or the rotating shaft 20 has a spiral groove 3111 on its sidewall facing the first sealing structure 31. When the rotating shaft 20 rotates, the material entering the spiral groove 3111 will move along the spiral groove 3111 towards the drying chamber 1101 due to the relative rotational compression of the rotating shaft 20 and the first sealing structure 31, thereby pushing the material back into the drying chamber 1101 and preventing 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 will be driven by the rotating shaft 20 to form an airflow in the spiral groove 3111 flowing towards the drying chamber 1101. The blowing action 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 material leakage.

[0124] In this embodiment, for example, the first sealing structure 31 has a helical groove 3111 on its sidewall facing the rotating shaft 20. The helical direction of the helical groove 3111 is the same as the rotation direction of the rotating shaft 20. Viewed along the axial direction X of the rotating shaft 20 from the side of the drying cylinder 11 near the first sealing structure 31 toward the drying chamber 1101, the helical direction of the helical groove 3111 is set to left-handed when the rotating shaft 20 rotates counterclockwise. Viewed along the axial direction X of the rotating shaft 20 from the side of the drying cylinder 11 near the first sealing structure 31 toward the drying chamber 1101, the helical direction of the helical groove 3111 is set to right-handed when the rotating shaft 20 rotates clockwise.

[0125] In some embodiments, the rotating shaft 20 has a spiral groove 3111 on its sidewall 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. Viewed along the axial direction X of the rotating shaft 20 from the side of the drying cylinder 11 near the first sealing structure 31 towards the drying chamber 1101, the spiral direction of the spiral groove 3111 is right-handed when the rotating shaft 20 rotates counterclockwise. Viewed along the axial direction X of the rotating shaft 20 from the side of the drying cylinder 11 near the first sealing structure 31 towards the drying chamber 1101, the spiral direction of the spiral groove 3111 is left-handed when the rotating shaft 20 rotates clockwise. When the rotating shaft 20 rotates relative to the first sealing structure 31, the material entering the spiral groove 3111, due to its lower speed than the rotating shaft 20, will be thrown back into the drying chamber 1101 by inertia, thus effectively preventing material leakage. In some embodiments, the first sealing structure 31 is provided with a spiral groove 3111 on the sidewall facing the rotating shaft 20, and the rotating shaft 20 is provided with a spiral groove 3111 on the sidewall 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.

[0126] The first sealing structure 31 includes a sealing sleeve 311 and a fixing sleeve 312. The fixing sleeve 312 passes through the mounting hole 1106 and is fixed to the drying cylinder 11. A clearance groove is provided on the side of the fixing sleeve 312 away from the rotating shaft 20 and on the side closer to the drying cylinder 11, into which the end plate of the drying cylinder 11 extends. The sealing sleeve 311 is located between the rotating shaft 20 and the fixing sleeve 312 and is fixed to the fixing sleeve 312. A mounting groove is provided on the side of the fixing sleeve 312 closer to the rotating shaft 20, and the sealing sleeve 311 is accommodated within the mounting groove. In some embodiments, the sealing sleeve 311 and the fixing sleeve 312 are independently configured and detachably connected together, which facilitates the individual replacement and maintenance of either the sealing sleeve 311 or the fixing sleeve 312, reducing the maintenance cost of the drying equipment 1000. In some embodiments, the sealing sleeve 311 and the fixing sleeve 312 can be integrally formed to reduce the installation difficulty of the first sealing structure 31.

[0127] The heat insulation structure 32 is provided with a cooling chamber 3201 and a heat insulation chamber 3202. The heat insulation chamber 3202 is used to contain the heat insulation medium. The heat insulation medium is used to block the heat emitted by the drying cylinder 11, reduce the heat conducted to the first sealing structure 31 and the rotating shaft 20, and reduce the heat loss of the drying cylinder 11, thereby improving the drying effect of the drying cylinder 11 on the material. The cooling chamber 3201 is used to contain the cooling medium. The cooling chamber 3201 is located on the side of the heat insulation chamber 3202 away from the drying cylinder 11. The cooling medium is used to cool the heat insulation structure 32 and the first sealing structure 31 to reduce the temperature of the first sealing structure 31 and prevent it from failing due to heat. The cooling chamber 3201 can be connected to an external circulating heat dissipation structure. The cooling medium circulates in the cooling chamber 3201 and the circulating heat dissipation structure to remove heat from the heat insulation structure 32 and the first sealing structure 31, thereby preventing the temperature of the first sealing structure 31 from becoming too high. The cooling chamber 3201 and the heat insulation chamber 3202 are independently arranged and separated by a partition. In some embodiments, the heat insulation structure 32 can be integrally formed. In some embodiments, the heat insulation structure 32 can be separately arranged; for example, the heat insulation structure 32 can be assembled from multiple components. The heat insulation structure 32 and the drying cylinder 11 can be connected in a sealed manner.

[0128] The drying equipment 1000 also includes an air guiding structure 33. Along the axial direction X of the rotating shaft 20, the air guiding structure 33 is located on the side of the first sealing structure 31 away from the drying cylinder 11. An air passage 3101 communicating with the drying chamber 1101 is formed between the first sealing structure 31 and the rotating shaft 20. The air guiding structure 33 is provided with an air guiding passage 330 communicating with the air passage 3101. The air guiding passage 330 is bent. The drying equipment 1000 is also used to introduce gas into the guide airflow channel 330 and the ventilation airflow channel 3101 to achieve an airtight seal on the rotating shaft 20. The introduced gas can make the air pressure in the ventilation airflow channel 3101 greater than the air pressure in the drying chamber 1101, thereby reducing or preventing the material to be dried from entering the gap between the rotating shaft 20 and the first sealing structure 31, and blowing the material that has entered the gap between the rotating shaft 20 and the first sealing structure 31 back into the drying chamber 1101. In this way, while achieving the sealing function of the rotating shaft 20, the friction between the rotating shaft 20 and the first sealing structure 31 can be reduced, the rotational resistance of the rotating shaft 20 can be reduced, and the power consumption of the drying equipment 1000 can be reduced. When the material enters the guide airflow channel 330, the bend in the guide airflow channel 330 can also improve the blocking effect of the guide airflow channel 330 on the material, thereby effectively preventing material leakage.

[0129] The air guiding structure 33 includes a first air guiding element 331 and a second air guiding element 332. Along the axial direction X of the rotating shaft 20, the first air guiding element 331 is located between the second air guiding element 332 and the first sealing structure 31. The air guiding channel 330 includes a first flow channel section 3301 and a second flow channel section 3302 communicating with the first flow channel section 3301. The first flow channel section 3301 is formed between the first air guiding element 331 and the rotating shaft 20. The first flow channel section 3301 extends along the axial direction X of the rotating shaft 20 and communicates with the air passage 3101. The second flow channel section 3302 is formed between the first air guiding element 331 and the second air guiding element 332. The second flow channel section 3302 is bent along the radial direction Y of the rotating shaft 20. The first flow channel section 3301 and the second flow channel section 3302 form a meandering flow channel, which enables the air-guiding structure 33 to achieve an air seal with the rotating shaft 20. This allows the air-guiding structure 33 to block the material entering the air-guiding flow channel 330, improve the sealing effect between the rotating shaft 20 and the drying cylinder 11, and avoid material leakage.

[0130] The second flow channel section 3302 may include multiple interconnected sub-flow channel sections, at least two of which extend in different directions, so that the second flow channel section 3302 is arranged in a bent manner. The number of sub-flow channel sections can be specifically set according to actual needs, and is not specifically limited in this application. For example, the number of sub-flow channel sections can be 2, 3, 4, 5, etc. In some embodiments, the flow area of ​​different sub-flow channel sections can be set to be different, so that the second flow channel section 3302 forms a labyrinth channel, improving the sealing effect of the air guiding structure 33 at the corresponding second flow channel section 3302.

[0131] One of the first air guide member 331 and the second air guide member 332 is provided with an air guide groove 3311, and the other of the first air guide member 331 and the second air guide member 332 is provided with an air guide protrusion 3321. The air guide protrusion 3321 is located within the air guide groove 3311. A second flow channel section 3302 is formed between the air guide protrusion 3321 and the air guide groove 3311. Exemplarily, in this embodiment, the first air guide member 331 is provided with an air guide groove 3311, and the second air guide member 332 is provided with an air guide protrusion 3321. The air guide groove 3311 and the air guide protrusion 3321 can extend along the axial direction X of the rotating shaft 20, respectively. A sub-flow channel section extending along the radial direction Y of the rotating shaft 20 and a sub-flow channel section extending along the axial direction X of the rotating shaft 20 are formed between the first air guide member 331 and the second air guide member 332. The number of air guide grooves 3311 can be set to one, or the number of air guide grooves 3311 can be set to multiple. Multiple air guide grooves 3311 can be spaced apart along the radial direction Y of the rotating shaft 20. The number of air guide protrusions 3321 corresponds to the number of air guide grooves 3311.

[0132] In some embodiments, the heat insulation structure 32 is provided with an air inlet channel 3203 that communicates with the air guide channel 330. The air inlet channel 3203 is used to connect to an air source, which supplies air to the air guide channel 330 through the air inlet channel 3203. The air guide channel 330 further includes a third flow channel section 3303 connected between the second flow channel section 3302 and the air inlet channel 3203.

[0133] The first air guide 331 includes a first air guide portion 3312 and a second air guide portion 3313. The first air guide portion 3312 is disposed on the side of the second air guide portion 3313 along the axial direction X of the rotating shaft 20, near the drying cylinder 11. The first air guide portion 3312 is located between the heat insulation structure 32 and the rotating shaft 20. The side of the first air guide portion 3312 away from the second air guide portion 3313 can be sealed and attached to the fixing sleeve 312 of the first sealing structure 31. The side of the second air guide portion 3313 facing the drying cylinder 11 can be sealed and attached to the side of the heat insulation structure 32 away from the drying cylinder 11. A third flow channel section 3303 can be disposed in the second air guide portion 3313. The second air guide 332 is located between the rotating shaft and the second air guide portion 3313.

[0134] The drying equipment 1000 also includes a second sealing structure 34. Along the axial direction X of the rotating shaft 20, the second sealing structure 34 is located on the side of the gas guiding structure 33 away from the drying cylinder 11. The second sealing structure 34 is sealingly connected to the side wall of the rotating shaft 20 and the side wall of the gas guiding structure 33 away from the first sealing structure 31 along the axial direction X of the rotating shaft 20, respectively. The second sealing structure 34 is used to seal the side of the gas guiding structure 33 away from the first sealing structure 31, so that the gas entering the gas guiding structure 33 flows towards the first sealing structure 31, and improves the sealing effect between the rotating shaft 20 and the drying cylinder 11, preventing material leakage to other parts of the rotating shaft 20.

[0135] The second sealing structure 34 includes a first sealing element 341 and a second sealing element 342. The first sealing element 341 is sleeved on the rotating shaft 20 and fixed to the rotating shaft 20. The second sealing element 342 is arranged around the first sealing element 341 and is sealed to the first sealing element 341. The first sealing element 341 and the second sealing element 342 are dynamically sealed, with the first sealing element 341 being a moving ring and the second sealing element 342 being a stationary ring.

[0136] The second sealing structure 34 also includes a sealing seat 343 and a connecting pipe 344. The sealing seat 343 is sleeved on the rotating shaft 20. The sealing seat 343 is in sealed contact with the first air guide 331. A sealing groove 3431 is provided on the side of the sealing seat 343 facing the rotating shaft 20. The second sealing element 342 is disposed in the sealing groove 3431. A sealing cavity 3432 is formed between the second sealing element 342 and the groove wall of the sealing groove 3431 on the side away from the rotating shaft 20. The connecting pipe 344 is connected to the sealing cavity 3432. The connecting pipe 344 is used to connect to a gas source and to supply gas to the sealing cavity 3432. The second sealing element 342 achieves a dynamic seal with the first sealing element 341 under the pressure of the gas.

[0137] In some embodiments, the second sealing structure 34 further includes a cooling pipe 345. The sealing seat 343 is provided with a cooling channel, and the cooling pipe 345 is connected to the cooling channel. The cooling pipe 345 is used to introduce a cooling medium into the cooling channel to dissipate heat from the first seal 341, the second seal 342, the sealing seat 343, and the rotating shaft 20. This prevents excessive temperature caused by friction when the first seal 341 and the second seal 342 rotate relative to each other, thereby preventing sealing failure between the first seal 341 and the second seal 342 and improving the reliability of the second sealing structure 34.

[0138] The drying equipment 1000 also includes a fixed base 35. The fixed base 35 is sleeved on the rotating shaft 20. The side of the fixed base 35 closest to the drying cylinder 11 is connected to the heat insulation structure 32. The fixed base 35, the heat insulation structure 32, the air guiding structure 33, the second sealing structure 34, and the rotating shaft 20 enclose an installation space 3501. In some cases, when the first sealing structure 31 and the second sealing structure 34 experience sealing failure (e.g., due to fatigue aging), the installation space 3501 can serve as a buffer space to buffer leaked material. When the drying equipment 1000 needs to operate without stopping, it can complete the current task before stopping for maintenance, avoiding the problem of immediate shutdown due to sealing failure and greatly improving the reliability of the drying equipment 1000.

[0139] In some embodiments, the mounting base 35 is provided with a viewing window 351 communicating with the installation space 3501. The viewing window 351 allows for easy observation of whether any material is leaking in the installation space 3501, facilitating timely shutdown and maintenance of the drying equipment 1000 in case of leakage, and also facilitating inspection and maintenance of the second sealing structure 34, the air guiding structure 33, and the heat insulation structure 32, as well as the removal of leaked material. In some embodiments, the mounting base 35 may be integrally formed. In some embodiments, the mounting base 35 may be modular, for example, it may be assembled from multiple components.

[0140] In some embodiments, the drying apparatus 1000 further includes a flow guide sleeve 22. A flow guide groove 211 is formed on the rotating shaft 20 along the axial direction X. The flow guide sleeve 22 is disposed within the flow guide groove 211. A heat dissipation channel 201 is formed between the flow guide sleeve 22 and the rotating shaft 20. The heat dissipation channel 201 is used to contain a cooling medium, which is used to cool the rotating shaft 20. The cooling medium may include, but is not limited to, a liquid; or it may be a gas. For example, the cooling medium may be water, oil, etc.

[0141] The guide channel 211 extends from the end of the rotating shaft 20 toward the drying cylinder 11. Along the axial direction of the rotating shaft 20, the guide channel 211 is located outside the drying chamber 1101 to reduce heat loss within the drying chamber 1101. Along the axial direction X of the rotating shaft 20, the guide channel 211 extends to the positions of the rotating shaft 20 corresponding to the first sealing structure 31, the air guiding structure 33, the second sealing structure 34, and the fixing seat 35, to fully dissipate heat from the first sealing structure 31 and the second sealing structure 34, preventing them from failing due to heat and sealing failure. This ensures that the first sealing structure 31 and the second sealing structure 34 form a long-term reliable sealing connection with the rotating shaft 20, improving the reliability of the drying equipment 1000.

[0142] In some embodiments, the drying apparatus 1000 further includes a heating structure. The heating structure is used to heat the drying cylinder 11 to accelerate the drying rate of the material to be dried.

[0143] In this embodiment, based on the first sealing structure 31, the air guiding structure 33, the second sealing structure 34, the heat insulation structure 32, the flow guiding groove 211, and the flow guiding sleeve 22 disposed on the rotating shaft 20, multiple sealing structures and multiple heat dissipation structures are formed between the rotating shaft 20 and the drying cylinder 11. This can effectively seal the space between the rotating shaft 20 and the drying cylinder 11 and dissipate heat from the rotating shaft 20, effectively avoiding the problem of seal failure between the rotating shaft 20 and the drying cylinder 11 due to heat, and greatly improving the reliability of the drying equipment 1000.
