Description

Technical Field

[0001] This utility model belongs to the technical field of cathode material drying devices, specifically relating to a cathode material drying device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Lithium batteries are a relatively environmentally friendly new type of energy battery. In the production process of lithium batteries, the positive electrode material after the reaction needs to be dried to ensure the safety of battery use. This process requires the use of positive electrode material drying equipment.

[0004] In existing technologies, the material to be dried is typically placed on a rack, which is then placed directly inside the drying equipment for drying. When improper installation, debugging, or maintenance leads to installation deviations or loose fasteners, the drying equipment vibrates during operation. This causes the rack to easily move inside the drying equipment, potentially colliding with the inner wall and causing wear and tear, hindering normal operation. Furthermore, the positive electrode material is usually placed in a tray, which is then placed directly on the rack. It's difficult to keep the tray in place, and due to the rack's height and multiple layers, it may tilt when removed, causing the positive electrode material in the tray to spill, inconvenient for operators, and affecting the stability of the placed positive electrode material. Utility Model Content

[0005] The purpose of this invention is to provide a positive electrode material drying device that can prevent the frame from colliding with the inner wall of the drying device, while limiting the position of the positive electrode material placed on the frame, thus ensuring the stability of the positive electrode material during placement.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] In a first aspect, embodiments of this utility model provide a cathode material drying device, including a drying chamber, a frame, and a material holding frame. The frame is placed inside the drying chamber, and sliders are respectively provided on the left and right sides of the frame. Sliding grooves are respectively provided on the left and right inner sides of the drying chamber. The sliders are installed in the sliding grooves and fixed by inserting rods. The material holding frame is placed on a partition of the frame, and limiting grooves are provided on the left and right sides of the material holding frame. Limiting blocks are provided on the partition at positions corresponding to the limiting grooves, and the limiting blocks can extend into the limiting grooves to limit the material holding frame.

[0008] As a further technical solution, an installation block is provided on the inner side of the drying oven, and a sliding groove is provided on the installation block, the sliding groove being T-shaped.

[0009] As a further technical solution, the position of the slider on the frame corresponds to the position of the T-shaped slide groove. The slider is a T-shaped slider, the shape of the T-shaped slider matches the shape of the T-shaped slide groove, and the T-shaped slider can slide within the T-shaped slide groove.

[0010] As a further technical solution, a socket is provided in the middle of the mounting block, and a through hole is provided on the T-shaped slider at a position corresponding to the socket. The insertion rod passes through the socket on the mounting block and the through hole on the T-shaped slider for limiting.

[0011] As a further technical solution, the frame is provided with multiple horizontally placed partitions, with a set distance between adjacent partitions, and each partition is provided with a corresponding material holding frame.

[0012] As a further technical solution, the material holding frame is a cuboid box structure with an open top.

[0013] As a further technical solution, the partition is provided with two L-shaped positioning plates and two limiting blocks to limit the material holding frame. The two L-shaped top plates are positioned opposite each other at the two rear corners of the material holding frame, and the two limiting blocks are positioned opposite each other at the side positions in front of the material holding frame.

[0014] As a further technical solution, the limiting block is fixedly connected to one end of the screw, the screw is mounted on the fixing plate through a threaded hole, and the fixing plate is fixed on the partition.

[0015] As a further technical solution, both the limiting block and the limiting groove on the material holding frame are circular.

[0016] As a further technical solution, four rollers are provided at the four corners of the frame.

[0017] The beneficial effects of the above-described embodiments of this utility model are as follows:

[0018] The drying equipment provided by this utility model can fix the frame to the drying box body through the cooperation between the slider, the slide groove and the plug rod, so as to avoid the frame from colliding with the inner wall of the drying equipment when the drying box vibrates or is hit by other reasons, which would cause wear to the inside of the equipment. Through the cooperation between the upper limit groove of the material holding frame and the upper limit block of the partition, the material holding frame can be fixed to the partition of the frame body, thereby preventing the positive electrode material from spilling due to the tilt of the frame body.

[0019] The drying equipment provided by this utility model achieves the limitation of the frame in the length direction through the interlocking of the T-shaped slider and the T-shaped slide groove. By inserting the plug rod into the plug hole on the mounting block and the through hole on the T-shaped slider, the frame can be limited in the width direction, thereby preventing the frame from moving relative to the drying box.

[0020] The drying equipment provided by this utility model uses two L-shaped plates to fix the rear two corners of the material holding frame, preventing the material holding frame from sliding backward on the frame. Two limiting blocks press against the front limiting groove of the material holding frame, preventing the material holding frame from sliding forward on the frame. In addition, the limiting blocks are driven by screws, which are mounted on the partitions through fixing plates. When the material holding frame is removed from the frame, the limiting blocks can be slid out of the limiting grooves simply by the screws. Compared with using four L-shaped plates to fix the material holding frame, there is no need to lift the material holding frame, thereby minimizing the distance between the two partitions and increasing the amount of positive electrode material to be dried.

Detailed Implementation

[0029] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] Example 1

[0031] In a typical embodiment of this utility model, such as Figures 1 to 5 As shown, a cathode material drying device is provided, including a drying chamber 1, a frame, and a material holding frame. The frame is placed inside the drying chamber 1. Slider blocks are respectively provided on the left and right sides of the frame. Sliding grooves are respectively provided on the left and right inner sides of the drying chamber 1. The sliders are installed in the sliding grooves and fixed by insert rods 15. The material holding frame 9 is placed on the partition plate 5 of the frame. Limiting grooves 19 are provided on the left and right sides of the material holding frame 9. Limiting blocks 18 are provided on the partition plate 5 at positions corresponding to the limiting grooves 19. The limiting blocks 18 can extend into the limiting grooves 19 to limit the material holding frame 9.

[0032] The cathode material drying equipment provided above can fix the frame to the drying chamber 1 through the cooperation between the slider, the slide groove and the insertion rod 15, so as to avoid the frame from colliding with the inner wall of the drying equipment when the drying chamber 1 is vibrated or collided due to other reasons, which would cause the frame to wear on the inside of the equipment; through the cooperation between the upper limit groove 19 of the material holding frame 9 and the upper limit block 18 of the partition 5, the material holding frame 9 can be fixed on the partition 5 of the frame, thereby preventing the cathode material from spilling due to the tilt of the frame.

[0033] It is understood that the structure of the drying oven 1 is an existing structure. The drying oven 1 is equipped with components for drying the positive electrode material. The front side of the drying oven 1 is equipped with a door, and the right side is equipped with a controller 4. When the frame is pushed into the drying oven 1, the slider on the frame is inserted into the slide rail on the inner side of the drying oven 1, and the insert rod 15 is further inserted into the slider and the slide rail to prevent the slider from moving along the slide rail. At this time, when the body of the drying oven 1 is collided or vibrated, the frame and the drying oven 1 will vibrate synchronously, and the frame will not move inside the drying oven 1, thereby preventing the frame from colliding with the inner wall and internal components of the drying oven 1.

[0034] Furthermore, since the bottom of the drying chamber 1 is equipped with a connecting seat 8, the inner bottom surface of the drying chamber 1 is at a certain height from the ground. When the frame is pushed into or pushed out of the drying chamber 1, it is necessary to use a sloping inclined plate. At this time, the frame will tilt when it moves on the inclined plate. In particular, the weight of the dried positive electrode material becomes lighter. When the frame tilts, the holding frame 9 containing the positive electrode material may slip off the partition 5 of the frame. By extending the limiting block 18 on the partition 5 into the limiting groove 19 on the holding frame 9, the holding frame 9 is limited, thus preventing pollution and waste caused by the spillage of the positive electrode material.

[0035] In this embodiment, a mounting block 10 is provided at the center of the inner side of the drying oven 1. The mounting block 10 has a sliding groove, which is T-shaped. Furthermore, the position of the slider on the frame corresponds to the position of the T-shaped sliding groove 11. The slider is a T-shaped slider 13, and the shape of the T-shaped slider 13 matches that of the T-shaped sliding groove 11, and the T-shaped slider 13 can slide within the T-shaped sliding groove 11.

[0036] Understandably, the chute is not directly formed on the inner side of the drying chamber 1. Instead, the mounting block 10 with the chute is installed on the inner side of the drying chamber 1. This allows the mounting block 10 to be replaced separately when the chute wears down and the slider cannot slide in, while also preventing the chute from affecting the drying chamber 1. Furthermore, both the chute and the slider are T-shaped, allowing them to interlock when the slider slides into the chute. To achieve this interlocking between the T-shaped slider 13 and the T-shaped chute 11, the T-shaped slider 13 is shorter and located in the middle of the frame width, while the mounting block 10 is longer, approximately the same width as the chamber. The heights of the T-shaped slider 13 and the mounting block 10 are the same to ensure that the T-shaped slider 13 can slide into the chute of the mounting block 10.

[0037] In order to install the insertion rod 15, an insertion hole is provided in the middle of the mounting block 10, and a through hole 14 is provided on the T-shaped slider 13 at a position corresponding to the insertion hole. The insertion rod 15 passes through the insertion hole on the mounting block 10 and the through hole 14 on the T-shaped slider 13 for limiting.

[0038] It is understandable that when the frame is pushed into the drying chamber 1, the slider slides into the slide groove. At this time, the frame is limited in the length direction only by the interlocking of the T-shaped slider 13 and the T-shaped slide groove 11. In the width direction, the T-shaped slider 13 will still move in the T-shaped slide groove 11. Therefore, inserting the plug rod 15 into the plug hole on the mounting block 10 and the through hole 14 on the T-shaped slider 13 can limit the frame in the width direction.

[0039] In this embodiment, the frame is provided with multiple horizontally placed partitions 5. Adjacent partitions 5 are fixedly connected by connecting blocks 6 and connecting plates 12, and there is a set distance between adjacent partitions. Each partition 5 is provided with a corresponding material holding frame 9, which is a cuboid box structure with an open top. Four rollers are provided at the four corners of the frame.

[0040] Understandably, to improve drying efficiency, placing as much positive electrode material as possible on the rack will reduce the gap between two adjacent partitions 5. Generally, the height between the two partitions 5 is slightly greater than the height of the material holding frame 9. The material holding frame 9 adopts a cuboid box structure with an open top. The opening design allows hot air to directly contact the material surface, thereby improving the drying efficiency. By installing rollers at the bottom of the rack, it is easy to push the rack into or out of the drying chamber 1.

[0041] Furthermore, the partition 5 is provided with two L-shaped top plates and two limiting blocks 18 to limit the material holding frame 9. The two L-shaped positioning plates 20 are positioned opposite each other at the two rear corners of the material holding frame 9, and the two limiting blocks 18 are positioned opposite each other at the side position in front of the material holding frame 9.

[0042] Understandably, the two L-shaped plates fix the two rear corners of the material holding frame 9 to prevent the material holding frame 9 from sliding backward on the frame, and the two limiting blocks 18 press against the front limiting groove 19 of the material holding frame 9 to prevent the material holding frame 9 from sliding forward on the frame.

[0043] In this embodiment, the limiting block 18 is fixedly connected to one end of the screw 17, the screw 17 is installed on the fixing plate 16 through a threaded hole, the fixing plate 16 is fixed on the partition 5, and the limiting groove 19 on the limiting block 18 and the material holding frame 9 are both circular.

[0044] It is understandable that the threaded rod can rotate within the fixed plate 16. Since the threaded rod is connected to the fixed plate 16 through a threaded hole, the threaded rod can extend and retract during rotation, thereby causing the limiting block 18 to extend into or out of the limiting groove 19 on the material holding frame 9. By setting the limiting groove 19 and the limiting block 18 to be circular, it can be ensured that the limiting groove 19 and the limiting block 18 can match each other no matter how the threaded rod rotates.

[0045] The cathode material drying equipment provided in this embodiment, during use, places the cathode material in the holding frame 9, then places the holding frame 9 on the partition 5. By turning the screw 17, the screw 17 drives the limiting block 18 into the limiting groove 19 on the side wall of the holding frame 9, thus limiting the holding frame 9 on the partition 5. This prevents the cathode material on the partition 5 from easily spilling when the partition 5 is removed, which is beneficial for operators and improves the stability of the cathode material during placement. The frame is then pushed into the drying chamber 1. By inserting the T-shaped slider 13 into the T-shaped groove 11, and then through the through hole 14 on the T-shaped slider 13, the insertion rod 15 passes through the T-shaped slider 13, thus limiting the frame inside the cavity 2. This prevents the frame from moving inside the equipment and avoids collisions between the frame and the inner wall of the cavity 2, which is beneficial for the normal use of the drying equipment.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
