Description

Technical Field

[0001] This application relates to the field of disk dryers, and particularly to a suspended scraper for a disk dryer. Background Art

[0002] As an efficient solid-liquid separation and drying equipment, disk dryers are widely used in the fields of chemical industry, pharmaceuticals, food, and new energy. Especially in the process of preparing battery materials, the drying link has a crucial impact on the performance and quality of the materials. Disk dryers transfer heat to the materials through heat conduction to achieve moisture evaporation, featuring high efficiency and energy conservation, and are one of the key indispensable equipment in modern industrial production. With the development of technology, disk dryers have made remarkable progress in improving drying efficiency and reducing energy consumption, but the design of their core components still faces many challenges.

[0003] Currently, in traditional disk dryers, in order to achieve uniform spreading of materials, a scraper structure is usually adopted. The scraper generally realizes its functions in the following ways: one is to use the gravity to make the scraper contact the materials, and evenly distribute the materials on the surface of the drying disk through mechanical pressure; the second is to adjust the position of the scraper through a simple mechanical connection to adapt to different material characteristics; the third is to adopt a scraper design with a fixed height and cooperate with the rotation of the drying disk to complete the paving of the materials. Although the above methods can meet the drying requirements to a certain extent, the contact pressure between the scraper and the materials will cause particle breakage. Especially for battery materials with smaller particle sizes or fragile structures, particle breakage will not only affect the final quality of the product, but also increase the losses in the production process, thereby reducing the overall production efficiency. Summary of the Invention

[0004] In order to ensure uniform spreading of materials while reducing particle breakage, this application provides a suspended scraper for a disk dryer.

[0005] The suspended scraper for a disk dryer provided by this application adopts the following technical solutions: A suspended scraper for a disk dryer includes: A rake pipe, on which a plurality of rake blades are arranged at intervals along the height direction of the rake pipe, and rake plates are arranged on the rake blades; it further includes: An adjusting device, which is arranged between the rake pipe and the rake blade. The adjusting device includes a fine-tuning driving component arranged on the rake pipe, a monotonic control component arranged between the fine-tuning driving component and the rake blade, and a fixing component arranged between the rake pipe and the fine-tuning driving component; wherein the fine-tuning driving component and the monotonic control component need to be used in cooperation to synchronously adjust the height of a plurality of the rake plates up and down or individually adjust the height of a certain rake plate; the fixing component is used to lock the position of the rake plate.

[0006] By adopting the above technical solution, the suspended scraper can accurately adjust the interval between the rake plate and the drying disk according to different material characteristics and drying requirements. During specific adjustment, the fine-tuning drive assembly and the single-tone control assembly are used in combination, which can synchronously adjust the height of multiple rake plates up and down or individually adjust the height of a certain rake plate. In addition, the fixing assembly can lock the position of the rake plate to ensure its stability during operation. The suspended scraper utilizes a high-precision fine-tuning structure and combines the function of individually adjusting the height of a certain rake plate, so that the distance between the rake plate and the drying disk can be accurately controlled, thereby reducing the pressure on the material during the even spreading of the material and reducing the breakage rate of the material particles. It is particularly suitable for battery materials with smaller particle sizes or fragile structures. At the same time, by individually adjusting the height of a certain rake plate through the high-precision fine-tuning structure, it can adapt to the deviation of the installation position of the drying disk during installation, improve the performance and installation tolerance of the disk dryer, and enhance the protection effect on the material, the final quality of the product and the production efficiency during the drying process.

[0007] Optionally, the fine-tuning drive assembly includes: A carrier frame fixedly arranged under the rake pipe; An adjusting screw rod rotatably connected to the carrier frame; A rotating shaft rotatably connected to the carrier frame, and a driving bevel gear is fixedly sleeved on the rotating shaft; A driven bevel gear rotatably sleeved outside the adjusting screw rod and meshing with the driving bevel gear, and the tooth number ratio of the driven bevel gear to the driving bevel gear is not less than 5; A sun gear is arranged at one side of the driven bevel gear at an interval, and a connecting sleeve is fixedly arranged between the sun gear and the driven bevel gear, and the connecting sleeve is sleeved outside the adjusting screw rod; Planet gears are rotatably connected to the carrier frame and multiple planet gears are provided. A gear ring is arranged outside the multiple planet gears, and the multiple planet gears mesh with both the gear ring and the sun gear; A connecting seat is fixedly sleeved outside the adjusting screw rod and fixedly connected to the gear ring.

[0008] By adopting the above technical solution, when the adjusting screw rod is driven to rotate by the fine-tuning drive assembly, first, the rotating shaft drives the driving bevel gear to rotate. The driving bevel gear meshes with the driven bevel gear, thereby driving the driven bevel gear to rotate. Then, the driven bevel gear drives the sun gear to rotate synchronously through the connecting sleeve. The sun gear meshes with multiple planet gears, and the gear ring outside the multiple planet gears rotates accordingly. The gear ring is fixedly connected to the connecting seat, and finally the connecting seat drives the adjusting screw rod to rotate. Among them, multi-stage fine-tuning is realized by using bevel gear transmission combined with a planetary gear train, and the height of the rake plate is adjusted with high precision in combination with the single-tone control assembly.

[0009] Optionally, the thread of the adjusting screw is a fine pitch thread.

[0010] By adopting the above technical solution, the fine pitch thread can further improve the adjustment accuracy. Since the pitch of the fine pitch thread is smaller, more subtle height adjustment can be achieved at the same rotation angle, which can better meet the precise requirements of different materials for the height of the scraper and reduce the particle breakage rate.

[0011] Optionally, the monotonic control assembly includes: An adjusting sleeve, threadedly connected to the outside of the adjusting screw; Two clamping plates, symmetrically abutted against the outside of the adjusting sleeve; A support frame, sleeved on the outside of the adjusting sleeve, a power motor is arranged on the support frame, and a connecting rod is fixedly arranged between the support frame and the rake blade; A clamping screw, fixedly arranged on the output shaft of the power motor; An adjusting plate, arranged at intervals on the side of the clamping plate away from the adjusting sleeve, the adjusting plate is fixedly connected to the clamping plate and an adjusting cavity is formed between the two, the clamping screw is threadedly connected to the adjusting plate, and one end of the clamping screw can extend into the adjusting cavity; A locking member, arranged between the adjusting plate and the rake pipe, for fixing the position of the support frame; A linkage member, arranged between the two clamping plates, for driving the two clamping plates to move synchronously and in opposite directions.

[0012] By adopting the above technical solution, when adjusting the height of a certain rake plate through the monotonic control assembly, first lock the positions of the remaining support frames and rake blades that are not adjusted through the locking member, then start the power motor, the power motor drives the clamping screw to rotate, and the threaded connection between the clamping screw and the adjusting plate causes the adjusting plate to move along the axial direction of the clamping screw. When the adjusting plate moves, it is fixedly connected to the clamping plate and drives the clamping plate to move synchronously. At the same time, the linkage member ensures that the two clamping plates always move synchronously and in opposite directions, so that the two clamping plates clamp and connect the adjusting sleeve. Since the adjusting sleeve is threadedly connected to the adjusting screw, when the fine adjustment drive assembly drives the adjusting screw to rotate, the adjusting screw can successively drive the adjusting sleeve, the clamping plate, the adjusting plate, the clamping screw, the power motor, the support frame, the connecting rod, the rake blade and the rake plate to move up and down, so that the height of a certain rake plate can be adjusted. When all the rake plates are adjusted to the required positions, all the power motors can be started simultaneously to synchronously drive all the clamping plates to clamp the adjusting sleeve, so as to lock the positions of all the rake plates and rake blades. Among them, the linkage member improves the stability of the clamping plate movement, reduces the problem of the adjusting sleeve getting stuck or shifting due to uneven unilateral force on the clamping plate, and simplifies the operation process. In addition, the locking member can lock the positions of the remaining rake plates that do not need to be adjusted during the adjustment process of a certain rake plate.

[0013] Optionally, the locking member includes locking blocks spaced apart on a side of the adjusting plate away from the clamping plate, a plurality of telescopic rods fixed between the locking blocks and the adjusting plate, and locking springs sleeved outside the telescopic rods; wherein the locking block abuts against the inner wall of the rake pipe, the locking spring is in a compressed state and gives the locking block a force towards the inner wall of the rake pipe, and the frictional force between the locking block and the rake pipe is greater than the gravity of the monotonic control assembly.

[0014] By adopting the above technical solution, when a certain rake plate needs to be adjusted and the positions of the remaining rake plates that do not need to be adjusted are locked by the locking member, first start the power motor. The power motor drives the clamping screw to rotate in the reverse direction. The clamping screw drives the adjusting plate to move towards the side close to the locking block. At the same time, the linkage member ensures that the two clamping plates and the two adjusting plates move synchronously in the reverse direction. Since the plurality of telescopic rods connect the locking block and the adjusting plate, and the locking spring is sleeved outside the telescopic rod, when the adjusting plate moves towards the side close to the locking block, the locking spring will push the locking block towards the inner wall of the rake pipe and make the locking block tightly abut against the inner wall of the rake pipe. Due to the elastic force of the locking spring, sufficient frictional force can be generated between the locking block and the inner wall of the rake pipe, and this frictional force is greater than the gravity of the monotonic control assembly, so as to ensure that the locking block can be firmly fixed on the inner wall of the rake pipe and prevent the monotonic control assembly from accidentally moving in the non-adjustment state. The locking member keeps the positions of the remaining rake plates stable when adjusting the height of a certain rake plate, improving the convenience for the staff to adjust a certain rake plate alone.

[0015] Optionally, the linkage member includes a hinge shaft fixed on the support frame, and two connecting rods that are arranged crosswise and rotatably sleeved outside the hinge shaft; one end of the connecting rod is hinged to one of the clamping plates, and the other end is slidably connected to the other clamping plate.

[0016] By adopting the above technical solution, the linkage member enables the two clamping plates to move synchronously in the reverse direction, so that problems such as jamming or offset of the adjusting sleeve caused by uneven force on one side of the clamping plate are not likely to occur. In addition, the linkage member improves the adjustment efficiency and enhances the coordination and reliability of the movement of the clamping plate.

[0017] Optionally, a clamping layer with a high coefficient of friction and wear resistance is laid on a side of the clamping plate close to the adjusting sleeve.

[0018] By adopting the above technical solution, the clamping layer with a high coefficient of friction and wear resistance can enhance the frictional force between the clamping plate and the adjusting sleeve, ensure the stable position of the adjusting sleeve during the clamping process, and avoid loosening of the clamping plate due to vibration or external force. At the same time, the wear-resistant material can extend the service life of the clamping plate and reduce the maintenance frequency.

[0019] Optionally, a plurality of adjustment grooves corresponding to the rake blades one by one are formed in the rake pipe along its height direction. The connecting rod can move up and down within the adjustment grooves, and a sealing baffle for shielding the adjustment grooves is fixedly arranged on the rake blades.

[0020] By adopting the above technical solution, the adjustment grooves formed in the rake pipe provide a space for the connecting rod to move up and down, enabling the rake blades and the rake plates to accurately adjust their heights according to the material characteristics, thereby optimizing the material spreading effect and reducing particle breakage. The arrangement of the sealing baffle can shield the adjustment grooves to prevent materials from entering the adjustment grooves and causing jamming or contamination.

[0021] Optionally, the fixing assembly includes: A first fixing bolt, which is threadedly connected to the rake pipe, and one end of the first fixing bolt presses against the top of the adjusting screw; A second fixing bolt, which is threadedly connected to the rake pipe, and one end of the second fixing bolt presses against the side wall of the adjusting screw.

[0022] By adopting the above technical solution, the first fixing bolt and the second fixing bolt respectively press and fix the adjusting screw from the top and the side wall, thereby realizing double locking of the adjusting screw, making the adjusting screw not easily rotate due to factors such as vibration during the working process, ensuring the stability of the positions of the rake plates and the rake blades, and improving the accuracy and reliability of the suspended scraper during the material spreading process.

[0023] Optionally, the rake plate is detachably connected to the rake blade.

[0024] By adopting the above technical solution, the detachable connection between the rake plate and the rake blade enables the rake plate to be conveniently replaced after wear or damage, and is also convenient for selecting a suitable rake plate material or structure according to different material characteristics, improving the adaptability and flexibility of the disk dryer.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: The suspended scraper utilizes a high-precision fine-tuning structure and combines the function of individually adjusting the height of a certain rake plate, enabling the distance between the rake plate and the drying disk to be accurately controlled. Thus, during the process of evenly spreading the material, the pressure on the material can be reduced, and the breakage rate of the material particles can be lowered. It is particularly suitable for battery materials with small particle sizes or fragile structures. At the same time, by individually adjusting the height of a certain rake plate through the high-precision fine-tuning structure, it can adapt to the deviation of the installation position of the drying disk during the installation process, improve the performance and installation fault tolerance rate of the disk dryer, and enhance the protection effect on the material, the final quality of the product, and the production efficiency during the drying process; In the fine-tuning drive assembly, a multi-stage fine-tuning is achieved by using bevel gear transmission in combination with a planetary gear train, and the height of the rake plate is adjusted with high precision by combining with the monotonic control assembly, which can better meet the precise requirements of different materials for the height of the scraper blade and reduce the particle breakage rate; In the monotonic control assembly, when all the rake plate positions are adjusted to the required positions, all the power motors can be started simultaneously to synchronously drive all the clamping plates to clamp the adjusting sleeve, thereby locking the positions of all the rake plates and rake blades; The locking component can lock the positions of the remaining rake plates that do not need to be adjusted when adjusting a certain rake plate, improving the convenience for the staff to adjust a certain rake plate individually; The linkage component enables the two clamping plates to move synchronously in the opposite direction, reducing the problems of jamming or offset of the adjusting sleeve caused by uneven unilateral force on the clamping plates, simplifying the operation process, enhancing the coordination and reliability of the movement of the clamping plates, and improving the adjustment efficiency; The fixing component realizes double locking of the adjusting screw, making the adjusting screw not easily rotate due to factors such as vibration during the working process, ensuring the stability of the positions of the rake plate and rake blade, and improving the accuracy and reliability of the suspended scraper during the material spreading process.

Detailed implementation manners

[0028] The following will further describe the present application in detail with reference to Figures 1-6 the accompanying drawings.

[0029] After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present application, it is protected by the Patent Law.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts fall within the scope of protection of the present application.

[0031] The embodiments of the present application disclose a suspended scraper for a disk dryer. Refer to Figure 1 , the suspended scraper of the disk dryer includes a rake pipe 1, a plurality of rake blades 2 arranged on the rake pipe 1, and a rake plate 3 installed on the rake blades 2. A connecting bolt 4 is arranged between the rake plate 3 and the rake blade 2. One end of the connecting bolt 4 penetrates through the rake plate 3 and is threadedly connected with a nut to the rake blade 2. The rake plate 3 and the rake blade 2 are detachably connected, which is convenient to replace rake plates 3 with different shapes or sizes according to actual needs to adapt to different material characteristics and drying requirements. For example, a flat rake plate 3, a corrugated rake plate 3 or a serrated rake plate 3 can be selected to achieve different paving effects for different materials.

[0032] Refer to Figure 2 and Figure 3, the suspended scraper further includes an adjusting device 5, and the adjusting device 5 includes a fine-tuning driving component 51, a single-tone control component 52, and a fixing component 53. The fine-tuning driving component 51 and the single-tone control component 52 are used in cooperation to synchronously adjust the height of multiple rake plates 3 up and down or individually adjust the height of a certain rake plate 3, while the fixing component 53 is used to lock the position of the rake plate 3.

[0033] Specifically, referring to Figure 1 and Figure 2 , the fine-tuning driving component 51 includes a carrier 511, an adjusting screw 512, a rotating shaft 513, a driving bevel gear 514, a driven bevel gear 515, a sun gear 516, a plurality of planet gears 517, a ring gear 518, and a connecting seat 519. Among them, the carrier 511 is fixedly arranged below the rake pipe 1, and the adjusting screw 512 is rotatably connected to the carrier 511. The rotating shaft 513 is also rotatably connected to the carrier 511. The driving bevel gear 514 is fixedly sleeved outside the rotating shaft 513, and a handwheel 5110 is fixedly sleeved at one end of the rotating shaft 513. The driven bevel gear 515 is rotatably sleeved outside the adjusting screw 512 and meshes with the driving bevel gear 514, and the tooth number ratio of the two is not less than 5. The sun gear 516 is arranged at an interval on one side of the driven bevel gear 515, and a connecting sleeve 5111 is fixedly arranged between the sun gear 516 and the driven bevel gear 515. The connecting sleeve 5111 is sleeved outside the adjusting screw 512. A plurality of planet gears 517 are rotatably connected to the carrier 511, and a ring gear 518 is arranged outside the plurality of planet gears 517. The planet gears 517 are respectively meshed with the ring gear 518 and the sun gear 516. The connecting seat 519 is fixedly sleeved outside the adjusting screw 512 and is fixedly connected to the ring gear 518.

[0034] The thread of the adjusting screw 512 adopts a fine-pitch thread to improve the fine-tuning accuracy. For example, the pitch of the fine-pitch thread is 0.5 mm or less, which enables only a small displacement to be achieved per revolution, thereby realizing high-precision fine-tuning. In addition, the fine-pitch thread also has a self-locking property and can maintain a stable state without external force, avoiding position deviation caused by vibration or other factors.

[0035] When the adjusting screw 512 is driven to rotate by fine-tuning the driving component 51, first, the handwheel 5110 is rotated. The handwheel 5110 drives the rotating shaft 513 to rotate, and the rotating shaft 513 drives the driving bevel gear 514 to rotate. The driving bevel gear 514 meshes with the driven bevel gear 515, so as to drive the driven bevel gear 515 to rotate. Then, the driven bevel gear 515 drives the sun gear 516 to rotate synchronously through the connecting sleeve 5111. The sun gear 516 meshes with a plurality of planet gears 517, and the tooth ring 518 outside the plurality of planet gears 517 rotates accordingly. The tooth ring 518 is fixedly connected to the connecting seat 519, and finally drives the adjusting screw 512 to rotate through the connecting seat 519. Among them, multi-stage fine-tuning is realized by using bevel gear transmission combined with a planetary gear train, and the height of the harrow plate 3 is adjusted with high precision by combining the monotonic control component 52.

[0036] Referring to Figure 4 and Figure 5 As shown in FIGS. 7 and 8, the monotonic control component 52 includes an adjusting sleeve 521, two clamping plates 522, a support frame 523, a clamping screw 524, an adjusting plate 525, a locking member 526 and a linkage member 527. The adjusting sleeve 521 is threadedly connected to the outside of the adjusting screw 512, and the two clamping plates 522 are symmetrically abutted against the outside of the adjusting sleeve 521. The support frame 523 is sleeved on the outside of the adjusting sleeve 521, and a power motor 528 is arranged on the support frame 523. A connecting rod 529 is also fixedly arranged between the support frame 523 and the harrow blade 2. A plurality of adjusting grooves 11 are formed in the harrow pipe 1 along its height direction, and each adjusting groove 11 is correspondingly arranged with a harrow blade 2. The connecting rod 529 can move up and down in the adjusting groove 11, so as to realize the vertical adjustment of the harrow blade 2 and the harrow plate 3. A sealing baffle 5210 is fixedly arranged on the harrow blade 2 to block the adjusting groove 11 and prevent materials from entering the adjusting groove 11 to cause blockage or pollution. The clamping screw 524 is fixedly arranged on the output shaft of the power motor 528. The adjusting plate 525 is arranged at an interval on the side of the clamping plate 522 away from the adjusting sleeve 521. The adjusting plate 525 is fixedly connected to the clamping plate 522 to form an adjusting cavity 5211. The clamping screw 524 is threadedly connected to the adjusting plate 525, and one end of the clamping screw 524 can extend into the adjusting cavity 5211. The locking member 526 is arranged between the adjusting plate 525 and the harrow pipe 1 to fix the position of the support frame 523. The linkage member 527 is arranged between the two clamping plates 522 to drive the two clamping plates 522 to move synchronously and in opposite directions.

[0037] A layer of clamping layer with a high coefficient of friction and wear resistance is laid on the side of the clamping plate 522 close to the adjusting sleeve 521. The clamping layer can be made of wear-resistant rubber, polyurethane material or ceramic material. The clamping layer can not only increase the friction between the clamping plate 522 and the adjusting sleeve 521, but also improve the clamping effect.

[0038] When adjusting the height of a certain harrow board 3 through the monotonic control component 52, first lock the positions of the remaining non-adjustable support frames 523 and harrow blades 2 through the locking component 526. Then start the power motor 528. The power motor 528 drives the clamping screw 524 to rotate. The threaded connection between the clamping screw 524 and the adjusting plate 525 causes the adjusting plate 525 to move axially along the clamping screw 524. When the adjusting plate 525 moves, it is fixedly connected to the clamping plate 522 and drives the clamping plate 522 to move synchronously. At the same time, the linkage component 527 ensures that the two clamping plates 522 always move synchronously and in opposite directions, so that the two clamping plates 522 clamp and connect the adjusting sleeve 521. Since the adjusting sleeve 521 is threadedly connected to the adjusting screw 512, after the fine-tuning drive component 51 drives the adjusting screw 512 to rotate, the adjusting screw 512 can drive the adjusting sleeve 521, the clamping plate 522, the adjusting plate 525, the clamping screw 524, the power motor 528, the support frame 523, the connecting rod 529, the harrow blade 2 and the harrow board 3 to move up and down in sequence, so as to adjust the height of a certain harrow board 3. When the positions of all the harrow boards 3 are adjusted to the required positions, all the power motors 528 can be started simultaneously to drive all the clamping plates 522 to clamp the adjusting sleeve 521 synchronously, so as to lock the positions of all the harrow boards 3 and harrow blades 2. The locking component 526 can lock the positions of the remaining non-adjustable harrow boards 3 during the adjustment process of a certain harrow board 3.

[0039] Specifically, referring to Figure 5 and Figure 6 , the locking component 526 includes a locking block 5261, a plurality of telescopic rods 5262 and a locking spring 5263. The locking blocks 5261 are arranged at intervals on the side of the adjusting plate 525 away from the clamping plate 522. The plurality of telescopic rods 5262 are fixedly arranged between the locking block 5261 and the adjusting plate 525. The locking spring 5263 is sleeved outside the telescopic rod 5262. The locking block 5261 abuts against the inner wall of the harrow pipe 1. The locking spring 5263 is in a compressed state and gives the locking block 5261 a force towards the inner wall of the harrow pipe 1. The frictional force between the locking block 5261 and the harrow pipe 1 is greater than the gravity of the monotonic control component 52, so as to ensure that the locking component 526 can fix the positions of the remaining non-adjustable harrow boards 3 during the adjustment process of a certain harrow board 3.

[0040] When a certain rake plate 3 needs to be adjusted and the positions of the other rake plates 3 that do not need to be adjusted are locked by the locking component 526, first start the power motor 528. The power motor 528 drives the clamping screw 524 to rotate in the reverse direction. The clamping screw 524 drives the adjusting plate 525 to move towards the side close to the locking block 5261. At the same time, the linkage component 527 ensures that the two clamping plates 522 and the two adjusting plates 525 move synchronously in the reverse direction. Since a plurality of telescopic rods 5262 connect the locking block 5261 and the adjusting plate 525, and a locking spring 5263 is sleeved outside the telescopic rod 5262. When the adjusting plate 525 moves towards the side close to the locking block 5261, the locking spring 5263 will push the locking block 5261 towards the inner wall of the rake pipe 1 and make the locking block 5261 tightly abut against the inner wall of the rake pipe 1. Due to the elastic force of the locking spring 5263, sufficient friction can be generated between the locking block 5261 and the inner wall of the rake pipe 1, and this friction is greater than the gravity of the monotonic control component 52, so as to ensure that the locking block 5261 can be firmly fixed on the inner wall of the rake pipe 1 and prevent the monotonic control component 52 from accidentally moving in the non-adjustment state.

[0041] Referring to Figure 5 and Figure 6 , the linkage component 527 includes a hinge shaft 5271 and two mutually crossed connecting rods 5272. The hinge shaft 5271 is fixedly arranged on the support frame 523, and the two connecting rods 5272 are rotatably sleeved outside the hinge shaft 5271. One end of the connecting rod 5272 is hinged to one of the clamping plates 522, and the other end is slidably connected to the other clamping plate 522. When one clamping plate 522 moves, the other clamping plate 522 can be driven to move synchronously in the reverse direction through the connecting rod 5272, so as to ensure that the two clamping plates 522 always exert an equal clamping force on the adjusting sleeve 521 and avoid jamming or offset of the adjusting sleeve 521 caused by uneven unilateral force.

[0042] Referring to Figure 3 and Figure 4 , the fixing component 53 includes a first fixing bolt 531 and a second fixing bolt 532. The first fixing bolt 531 is threadedly connected to the rake pipe 1, and one end of it presses against the top of the adjusting screw 512; the second fixing bolt 532 is also threadedly connected to the rake pipe 1, and one end of it presses against the side wall of the adjusting screw 512. Through the dual locking effect of the first fixing bolt 531 and the second fixing bolt 532, the position of the adjusting screw 512 can be ensured to be stable, avoiding the position offset of the rake plate 3 and the rake blade 2 caused by vibration or other factors, and improving the accuracy and reliability of the suspended scraper during the material spreading process. The implementation principle of the suspended scraper of the disk dryer in the embodiment of the present application is as follows: The suspended scraper can accurately adjust the interval between the rake plate 3 and the drying disk according to different material characteristics and drying requirements. During specific adjustment, the fine-tuning drive assembly 51 and the monotonic control assembly 52 are used in combination to synchronously adjust the height of multiple rake plates 3 up and down or individually adjust the height of a certain rake plate 3. In addition, the fixing assembly 53 can lock the position of the rake plate 3 to ensure its stability during operation. Among them, the suspended scraper uses a high-precision fine-tuning structure and combines the function of individually adjusting the height of a certain rake plate 3, so that the distance between the rake plate 3 and the drying disk can be accurately controlled, thereby reducing the pressure on the material during the uniform spreading of the material and reducing the breakage rate of the material particles. It is particularly suitable for battery materials with small particle size or fragile structure; at the same time, by individually adjusting the height of a certain rake plate 3 through the high-precision fine-tuning structure, it can adapt to the deviation of the installation position of the drying disk during installation, improve the performance and installation tolerance of the disk dryer, and improve the protection effect on the material, the final quality of the product and the production efficiency during the drying process.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
