Description

Technical Field

[0001] This utility model relates to the field of battery electrode preparation technology, specifically to a slurry spraying and drying device for battery electrode preparation. Background Technology

[0002] With the continuous development of battery technology, the requirements for battery electrode preparation are also increasing. Battery electrodes are an important component of batteries, generally divided into positive and negative electrodes. Positive electrodes typically consist of positive active materials, conductive agents, binders, and current collectors. The positive active materials determine key performance indicators such as battery capacity and voltage. The composition of negative electrodes is similar to that of positive electrodes, mainly including negative active materials, conductive agents, binders, and current collectors. The quality of battery electrodes directly affects battery performance and lifespan. In the battery electrode preparation process, slurry drying is a crucial step. Traditional drying methods struggle to adapt to changes in object size using existing fixing devices, causing inconvenience in production and affecting product quality. Therefore, to address these problems, this utility model has been developed. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a slurry spraying and drying device for battery electrode preparation, comprising: a base; a drying structure, the bottom of which is fixedly connected to the top of the base; a flow guiding structure, the outer wall of which is fixedly connected to the inner wall of the drying structure; a stabilizing structure, the outer wall of which is fixedly connected to the outer wall of the drying structure; the stabilizing structure includes a stabilizing block, the outer wall of which is fixedly connected to the outer wall of the drying structure, a bidirectional lead screw slidably connected to the inner wall of the stabilizing block, a slider threadedly connected to the outer wall of the bidirectional lead screw, a fixing block fixedly connected to the outer wall of the slider, and a rubber block fixedly connected to the top of the fixing block, which can prevent the object from being crushed when fixing it, thus better protecting the object being dried; and a stabilizing rod slidably connected to the inner wall of the slider.

[0004] Preferably, the outer wall of the stabilizer bar is fixedly connected to the outer wall of the stabilizer block, and the bidirectional lead screw passes through the stabilizer block.

[0005] Preferably, the drying structure includes a protective shell, and a drying nozzle is fixedly connected to the outer wall of the protective shell.

[0006] Preferably, the flow guiding structure includes a flow guiding block, and a flow guiding plate is slidably connected to the inner wall of the flow guiding block.

[0007] Preferably, the structure of the guide plate near the drying nozzle is an arc-shaped structure. The arc-shaped structure of the guide plate in the guide structure guides the hot air sprayed from the drying nozzle to the item, making the hot air more uniform and gentle. The guide plate is fixedly connected to the guide block by fastening bolts.

[0008] Preferably, the outer wall of the guide block is fixedly connected to the inner wall of the protective shell, and the bidirectional lead screw passes through the protective shell and extends to both sides.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model features a stabilizing structure. The rotation of the bidirectional lead screw in the stabilizing structure drives the sliders to move in opposite directions, thereby changing the distance between the fixing blocks. This allows for the fixing of objects of different sizes, facilitating the drying process. When the size of the object changes, there is no need to replace the fixing device, improving production efficiency. A rubber block is fixed to the top of the fixing block to prevent the object from being damaged during fixing, better protecting the object being dried.

[0011] 2. This utility model, by setting up a flow guiding structure, uses the arc-shaped structure of the flow guiding plate in the flow guiding structure to direct the hot air sprayed from the drying nozzle to the object, making the hot air more uniform and gentle. This avoids the situation where the surface of the object is over-dried while the inside remains damp due to the hot air blowing directly on it, effectively improving the drying effect. The distance between the flow guiding plate and the object can be adjusted by tightening the bolts, thereby adjusting the amount of air blown onto the object's surface. This allows for flexible adjustment according to different drying needs, further improving the drying quality. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0018] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a slurry spraying and drying device for battery electrode preparation, comprising: a base 1; a drying structure 2, the bottom of which is fixedly connected to the top of the base 1; a flow guiding structure 3, the outer wall of which is fixedly connected to the inner wall of the drying structure 2; a stabilizing structure 4, the outer wall of which is fixedly connected to the outer wall of the drying structure 2; the stabilizing structure 4 includes a stabilizing block 41, the outer wall of which is fixedly connected to the outer wall of the drying structure 2, a bidirectional lead screw 42 slidably connected to the inner wall of the stabilizing block 41, a slider 43 threadedly connected to the outer wall of the bidirectional lead screw 42, a fixing block 45 fixedly connected to the outer wall of the slider 43, and a rubber block 46 fixedly connected to the top of the fixing block 45. A stabilizing rod 44 is slidably connected to the inner wall of the device. To facilitate the fixing of the object, the object is first placed on the fixing block 45 in the stabilizing structure 4. Then, the bidirectional lead screw 42 on the stabilizing block 41 is rotated. The rotation of the bidirectional lead screw 42 drives the slider 43 to move in opposite directions. The slider 43 drives the fixing block 45 to move, thereby fixing the object and facilitating the drying process. To ensure the stability of the slider 43, the stabilizing rod 44 penetrates the inner wall of the slider 43. In order to better protect the object and prevent it from being crushed, a rubber block 46 is fixed on the top of the fixing block 45. When the size of the object changes, the bidirectional lead screw 42 is rotated, and the distance between the fixing blocks 45 is changed by the slider 43, thereby adapting to objects of different sizes.

[0019] The outer wall of the stabilizing rod 44 is fixedly connected to the outer wall of the stabilizing block 41, and the bidirectional screw 42 passes through the stabilizing block 41. In use, the base 1 is fixed to the ground as the base of the whole equipment, and the drying structure 2 is fixed on the top of the base 1. When the drying nozzle 22 in the drying structure 2 is activated, the drying nozzle 22 on the protective shell 21 heats the air and sprays it outward, blowing the hot air toward the object to be dried, so that the moisture on the surface of the object evaporates, thereby achieving the purpose of drying.

[0020] The drying structure 2 includes a protective shell 21, and a drying nozzle 22 is fixedly connected to the outer wall of the protective shell 21.

[0021] The flow guiding structure 3 includes a flow guiding block 31, and a flow guiding plate 32 is slidably connected to the inner wall of the flow guiding block 31.

[0022] The structure of the guide plate 32 near the drying nozzle 22 is arc-shaped. The guide plate 32 is fixedly connected to the guide block 31 by the fastening bolt 33. When hot air blows directly onto the surface of the item, it can easily cause the surface to be over-dried while the inside remains damp, and may cause the surface to peel and crack. Now, the hot air sprayed from the drying nozzle 22 blows directly onto the guide plate 32 in the guide structure 3. Through the arc-shaped structure of the guide plate 32, the hot air is guided to the item, making the hot air more uniform and gentle, and the drying effect better. The guide plate 32 can be slid and fixed inside the guide block 31 by the fastening bolt 33, thereby adjusting the distance between the guide plate 32 and the item, and thus adjusting the amount of air blown onto the surface of the item.

[0023] The outer wall of the guide block 31 is fixedly connected to the inner wall of the protective shell 21, and the bidirectional screw 42 passes through the protective shell 21 and extends to both sides.

[0024] Working principle:

[0025] When in use, the base 1 is fixed to the ground as the base of the whole equipment, and the drying structure 2 is fixed on the top of the base 1. When the drying nozzle 22 in the drying structure 2 is activated, the drying nozzle 22 on the protective shell 21 heats the air and sprays it outward, blowing the hot air toward the object to be dried, so that the moisture on the surface of the object evaporates, thereby achieving the purpose of drying.

[0026] To facilitate fixing the object, the object is first placed on the fixing block 45 in the stabilizing structure 4. Then, the bidirectional lead screw 42 on the stabilizing block 41 is rotated. The rotation of the bidirectional lead screw 42 drives the slider 43 to move in opposite directions. The slider 43 drives the fixing block 45 to move, thereby fixing the object and facilitating the drying process. To ensure the stability of the slider 43, the stabilizing rod 44 passes through the inner wall of the slider 43. In order to better protect the object and prevent it from being crushed, a rubber block 46 is fixed on the top of the fixing block 45. When the size of the object changes, the bidirectional lead screw 42 is rotated, and the distance between the fixing blocks 45 is changed by the slider 43, thereby adapting to objects of different sizes.

[0027] Directly blowing hot air onto the surface of an item can easily cause the surface to become overly dry while the inside remains damp, potentially leading to peeling and cracking. Now, the hot air from the drying nozzle 22 blows directly onto the guide plate 32 in the airflow structure 3. The curved structure of the guide plate 32 guides the hot air to the item, making the hot air more even and gentle, resulting in better drying. Furthermore, the guide plate 32 can be fixed inside the guide block 31 by tightening the bolts 33, thereby adjusting the distance between the guide plate 32 and the item, and consequently, adjusting the amount of airflow reaching the item's surface.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
