Description

Technical Field

[0001] This utility model relates to the field of lithium hydroxide drying technology, specifically a lithium hydroxide drying device. Background Technology

[0002] Lithium hydroxide is an important raw material for preparing cathode materials for lithium-ion batteries, such as lithium cobalt oxide, lithium manganese oxide, and lithium iron phosphate, which have wide applications in new energy vehicles, portable electronic devices and other fields.

[0003] In the comparative case, patent publication number CN222352767U, this utility model relates to the field of lithium hydroxide drying technology, specifically a drying device for lithium hydroxide, including a drying chamber. A feeding hopper is connected to the top surface of the drying chamber, and a rotating shaft is rotatably connected to the lower end of the feeding hopper. A sealing discharge block is fixedly connected to the rotating shaft. A triangular block is fixedly connected to the inner wall of the lower end of the feeding hopper, with the bottom surface of the triangular block contacting the top surface of the sealing discharge block. A first servo motor is mounted on the side wall of the feeding hopper via a mounting base. The output shaft of the first servo motor is coaxially connected to one side of the outer wall of the rotating shaft. A magnetron body is mounted on the upper left wall of the drying chamber via a mounting base. A waveguide is connected to the magnetron body, extending through the outer wall of the drying chamber to the interior. A stirring rod is provided inside the drying chamber. This solution ensures the uniformity of material distribution within the drying chamber, ensuring that lithium hydroxide uniformly absorbs microwaves for heating, effectively improving drying efficiency and uniformity, and guaranteeing the uniformity and efficiency of the drying process.

[0004] However, in implementing the relevant technology, the above-mentioned drying device for lithium hydroxide has the following problems. In the comparative case, the output shaft of the first servo motor drives the rotating shaft to rotate along the feed hopper, so that the sealed discharge block and the triangular block are separated, and the lithium hydroxide falls into the drying box from the gap between the sealed discharge block and the triangular block, which facilitates the control of the feeding of lithium hydroxide. In the existing lithium hydroxide drying equipment, the material is added at one time, which easily causes accumulation and blockage, and the material cannot be screened and filtered, resulting in pollution and reducing the safety of the lithium hydroxide drying equipment.

[0005] Therefore, it is necessary to redesign and modify the lithium hydroxide drying equipment to effectively prevent the problems of material accumulation and blockage caused by adding material all at once during use, and the inability to screen and filter, which would lead to pollution.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the present invention provides a lithium hydroxide drying device, comprising:

[0024] Support frame 1, disc dryer 2 is fixedly installed on the inner side of support frame 1, feed cylinder 3 is connected to the top of disc dryer 2, and feed mechanism 4 is fixedly connected to the front and back ends of the top of disc dryer 2.

[0025] The feeding mechanism 4 includes a connecting frame 41, a frame 42, a servo motor 43, a first pulley 44, a belt 45, a bearing 46, a spiral feed cylinder 47, a second pulley 48, and a hopper 49. The front and back ends of the top of the disc dryer 2 are fixedly connected to the connecting frame 41. The top inner side of the connecting frame 41 is fixedly connected to the frame 42. The bottom right side of the frame 42 is fixedly connected to the servo motor 43. The output end of the servo motor 43 is fixedly connected to the first pulley 44. A belt 45 is fitted onto the surface of the first pulley 44. The left and right sides of the top inner side of the frame 42 are also connected to the connecting frame 41. A bearing 46 is fixedly connected, and a spiral feed cylinder 47 is movably connected to the inner cavity of the bearing 46. A second pulley 48 is fixedly sleeved on the surface of the spiral feed cylinder 47 and located between the bearings 46. One end of the belt 45 away from the first pulley 44 is sleeved on the surface of the second pulley 48. The first pulley 44 and the second pulley 48 are connected by the belt 45. A hopper 49 is connected to the bottom of the spiral feed cylinder 47. One end of the hopper 49 away from the spiral feed cylinder 47 is connected to the left side of the feed cylinder 3. Vibration mechanisms 5 are fixedly connected to the front and back ends of the right side of the feed cylinder 3.

[0026] refer to Figure 3 The vibration mechanism 5 includes a connecting plate 51, a sliding plate 52, a U-shaped rod 53, and a filter plate 54. The front and back ends of the right side of the feed cylinder 3 are fixedly connected to the connecting plate 51. The sliding plate 52 is slidably connected to the inner side of the connecting plate 51. The U-shaped rod 53 is fixedly connected to the center of the top of the sliding plate 52. The end of the U-shaped rod 53 away from the sliding plate 52 passes through the inside of the feed cylinder 3 and is fixedly connected to the filter plate 54. The drive assembly 6 is fixedly connected to the right side of the feed cylinder 3 and located inside the connecting plate 51.

[0027] As a technical optimization of this utility model, by setting up the vibration mechanism 5, the slide plate 52 can be moved by external force. The movement of the slide plate 52 drives the U-shaped rod 53 and the filter plate 54 to move accordingly. The filter plate 54 vibrates up and down inside the feed cylinder 3 to screen the material, thus avoiding the phenomenon of material accumulation on the filter plate 54 causing blockage.

[0028] refer to Figure 4 The drive assembly 6 includes a stepper motor 61 and a cam 62. The stepper motor 61 is fixedly connected to the right side of the feed cylinder 3 and inside the connecting plate 51. The output end of the stepper motor 61 is fixedly connected to the cam 62. The top of the cam 62 contacts the bottom of the slide plate 52. The front end and back end of the right side of the connecting plate 51 are both fixedly connected to a reset mechanism 7.

[0029] As a technical optimization of this utility model, by setting the drive component 6, the stepper motor 61 can work to drive the cam 62 to rotate. The cam 62 rotates clockwise and continuously contacts the slide plate 52, so that the slide plate 52 is subjected to force to complete the mechanical movement, thereby realizing the transmission of mechanical power and avoiding the situation where the cam 62 cannot contact the slide plate 52 to transmit power.

[0030] refer to Figure 4 The reset mechanism 7 includes a support 71, a telescopic rod 72, and a spring 73. The support 71 is fixedly connected to the front end and back end of the right side of the connecting plate 51. The telescopic rod 72 is fixedly connected to the inner cavity of the support 71. The bottom of the telescopic rod 72 passes through the bottom of the support 71 and is fixedly connected to the top of the slide plate 52. The spring 73 is sleeved on the surface of the telescopic rod 72. The top and bottom of the spring 73 are fixedly connected to the surface of the telescopic rod 72 and the top of the slide plate 52, respectively.

[0031] As a technical optimization of this utility model, the reset mechanism 7 enables the telescopic rod 72 to move up and down with the slide plate 52 to complete the retraction and extension. When the telescopic rod 72 retracts, it compresses and stores the elastic potential energy of the spring 73. When the telescopic rod 72 extends, it works with the spring 73 to actively reset, so that the slide plate 52 can be reset after movement, thus avoiding the inability of the machine to continue working due to the slide plate 52 not being able to reset after movement.

[0032] refer to Figure 4 A groove 8 is provided on the inner side of the connecting plate 51 at the position corresponding to the slide plate 52. The groove 8 is used in conjunction with the slide plate 52.

[0033] As a technical optimization of this utility model, the slide 8 enables the slide plate 52 to move up and down inside the slide 8, while also serving as a limit, thus preventing the slide plate 52 from deviating during movement.

[0034] refer to Figure 4The bottom of the stepper motor 61 is fixedly connected to a bracket 9, and the front and back ends of the bracket 9 are fixedly connected to the inner side of the connecting plate 51.

[0035] As a technical optimization of this utility model, the bracket 9 can assist the stepper motor 61 in working and also play a supporting and fixing role, thus avoiding mechanical vibration of the stepper motor 61 during operation.

[0036] The working principle and usage process of this utility model are as follows: When in use, the servo motor 43 is started, driving the first pulley 44 to rotate clockwise. The rotation of the first pulley 44 drives the belt 45 and the second pulley 48 to rotate synchronously. The rotation of the second pulley 48 drives the spiral feed cylinder 47 to rotate around the bearing 46. The rotation of the spiral feed cylinder 47 squeezes out the material inside, which continuously moves into the hopper 49. The hopper 49 guides the material into the feed cylinder 3. Then, the stepper motor 61 is started, driving the cam 62 to rotate clockwise. The cam 62 contacts the slide plate 52, and the slide plate 52, impacted by the movement, moves up and down along the groove 8 on the surface of the connecting plate 51. The up and down movement of the slide plate 52 drives the U-shaped rod 5... 3. The U-shaped rod 53 moves, causing the filter plate 54 to follow and cooperate with the feed cylinder 3 to vibrate and screen the incoming material. When the slide plate 52 returns to its original position, it actively returns to its original position in conjunction with the telescopic rod 72 and the spring 73. The spring 73 compresses and stores elastic potential energy and releases it, thereby pushing the telescopic rod 72 to extend and push the slide plate 52 to actively return to its original position. Finally, the material is vibrated and falls into the interior of the disc dryer 2. Under the action of the rake blades, it tumbles and stirs on the surface of the drying disc along an exponential spiral line and moves outward to the lower drying disc. The large and small discs are arranged alternately, and the material flows through the entire dryer. The drying disc is filled with saturated steam, hot water and other heating media. The heat is transferred to the material through the heat exchange between the partition walls, causing the moisture to evaporate. The dried material falls to the bottom and is sent to the discharge port by the rake blades. The moisture is discharged from the vent on the top cover.

[0037] In summary, this lithium hydroxide drying device, through the coordinated use of a support frame 1, a disc dryer 2, a feeding cylinder 3, a feeding mechanism 4, a connecting frame 41, a frame 42, a servo motor 43, a first pulley 44, a belt 45, a bearing 46, a spiral feed cylinder 47, a second pulley 48, a discharge hopper 49, and a vibration mechanism 5, achieves stable feeding. When the servo motor 43 is started, it drives the first pulley 44 to rotate clockwise. The rotation of the first pulley 44 drives the belt 45 and the second pulley 48 to rotate synchronously. The rotation of the second pulley 48 drives the spiral feed cylinder 47 to rotate around the bearing 46. The rotation of the spiral feed cylinder 47 continuously forces the material into the discharge hopper 49, which guides the material into the feeding cylinder 3 for drying. This achieves stable feeding, avoids blockage caused by single-feeding, and solves the problems of existing lithium hydroxide drying equipment where single-feeding easily causes accumulation and blockage, and the inability to filter and screen leads to contamination.
