When working, the vacuum pump is started, air in the evaporation box is extracted through the suction pipe, and a vacuum environment is formed in the evaporation box. Under the vacuum state, the boiling point of water is reduced, so that the moisture in the battery production material can evaporate at a lower temperature, avoiding damage to the microstructure of the battery material caused by local overheating in the traditional heating and drying mode. At the same time, since evaporation can be quickly carried out at a lower temperature, the possibility of unnecessary chemical reaction of the battery material due to long-time exposure to a high-temperature environment is reduced, greatly protecting the electrochemical performance and service life of the battery material.

Since the evaporation piece extends from both sides of the evaporation box to the outside of the box, and the third elbow pipes on both sides are connected through the heat inlet pipe and the heat outlet pipe, uniform and stable heating can be realized. The heat is stably transported to the evaporation box through the evaporation piece, ensuring uniform heat distribution in the evaporation box, so that the battery materials placed on the placing rack can be uniformly heated, overcoming the problem of local overheating in the traditional heating and drying process. Through this uniform heating method, the heating process of the battery materials can be accurately controlled, further preventing the destruction of the microstructure of the battery materials caused by uneven temperature, ensuring the consistency and stability of the battery materials, and improving the quality of the final battery products.

[0031] Through the vacuum mechanism 2, the vacuum pump 22 in the mechanism forms a complete air extraction passage through the suction pipe 21, the first elbow pipe 23, the second elbow pipe 25 and the dustproof sleeve 24. In operation, the vacuum pump 22 is started, and air is extracted from the evaporation box 4 through the suction pipe 21 to form a vacuum environment in the evaporation box 4. Under the vacuum state, the boiling point of water is lowered, so that the moisture in the battery production material can evaporate at a lower temperature, avoiding the damage to the microstructure of the battery material caused by local overheating in the traditional heating drying method. At the same time, since the evaporation can be carried out quickly at a lower temperature, the possibility of unnecessary chemical reaction of the battery material due to long time in high temperature environment is reduced, greatly protecting the electrochemical performance and service life of the battery material. This vacuum-assisted method not only speeds up the evaporation rate of moisture, but also significantly improves the evaporation efficiency, making the drying process more efficient, ensuring that the battery material can maintain its original excellent performance while removing moisture, meeting the strict requirements of modern battery production on quality and performance.

The observation window 6 is composed of tempered glass and a metal frame.

[0035] The dropping port at the top of the evaporation box 4 and the hinge-hinged cover plate 1 make it very convenient to place the materials. The size of the rack body 51 of the placing rack 5 is smaller than that of the dropping port at the top of the evaporation box 4, and the hanging blocks 52 around the top are provided with hanging holes, which facilitates the placing and taking out of the placing rack 5 into or out of the limiting frame 8 in the evaporation box 4 through the lifting device, avoiding the difficulty of placing and taking out materials in traditional equipment. At the same time, the observation window 6 in the middle of the front side of the evaporation box 4 is composed of tempered glass and a metal frame, and the operator can clearly observe the evaporation process in the evaporation box 4 through the observation window 6. This structure design enables the operator to monitor the moisture evaporation in real time, which is conducive to accurately controlling the production process and ensuring the controllability and operability of the production process, providing convenience for quality control and process adjustment in the battery production process, improving the fine degree of production, and meeting the strict requirements of modern battery production on accurate control of the production process.

Hot pipe 34 will be hot medium (such as hot water or steam) into the third elbow pipe 33, the heat of the hot medium is directed to the evaporation sheet 32 and then flows out from the hot pipe 35. Because the evaporation sheet 32 extends from both sides of the evaporation tank 4 to the outside of the tank, and the third elbow pipe 33 on both sides is communicated through the hot pipe 34 and the hot pipe 35, therefore, uniform and stable heating can be realized. The heat is stably delivered to the evaporation tank 4 through the evaporation sheet 32, ensuring uniform distribution of heat in the evaporation tank 4, so that the battery material placed on the placing rack 5 can be uniformly heated, overcoming the problem of local overheating in the traditional heating and drying process. Through this uniform heating method, the heating process of the battery material can be accurately controlled, further preventing the microstructure damage of the battery material caused by uneven temperature, ensuring the consistency and stability of the battery material, and improving the quality of the final battery product.

In operation, the vacuum pump 22 is started, and air is extracted from the evaporation box 4 through the suction pipe 21, so that a vacuum environment is formed in the evaporation box 4. Under the vacuum state, the boiling point of water is reduced, so that the moisture in the battery production material can evaporate at a lower temperature, avoiding the damage to the microstructure of the battery material caused by local overheating in the traditional heating and drying method. At the same time, since evaporation can be carried out quickly at a lower temperature, the possibility of unnecessary chemical reactions of the battery material due to long-time exposure to a high-temperature environment is reduced, greatly protecting the electrochemical performance and service life of the battery material. This vacuum-assisted method not only speeds up the evaporation rate of moisture, but also significantly improves the evaporation efficiency, making the drying process more efficient, ensuring that the battery material can maintain its original excellent performance while removing moisture, meeting the strict requirements of modern battery production on quality and performance.

The heat is stably delivered to the evaporation box 4 through the evaporation sheet 32, ensuring uniform heat distribution in the evaporation box 4, so that the battery material placed on the placing rack 5 can be uniformly heated, overcoming the problem of local overheating in the traditional heating and drying process. Through this uniform heating method, the heating process of the battery material can be accurately controlled, further preventing the microstructure damage of the battery material caused by uneven temperature, ensuring the consistency and stability of the battery material, and improving the quality of the final battery product.

[0045] The placement of the material is very convenient through the setting of the drop port at the top of the evaporation box 4 and the hinge-hinged cover plate 1. Moreover, the size of the rack body 51 of the placing rack 5 is smaller than that of the drop port at the top of the evaporation box 4, and the hanging blocks 52 around the top are provided with hanging holes, which facilitates the placement or removal of the placing rack 5 into or out of the limiting frame 8 in the evaporation box 4 through the lifting appliance, avoiding the difficulty of material placement and removal in traditional equipment.

This structural design enables the operator to monitor the moisture evaporation in real time, which is conducive to accurately controlling the production process and ensuring the controllability and operability of the production process, providing convenience for quality control and process adjustment in the battery production process, improving the fine degree of production, and meeting the strict requirements of modern battery production for accurate control of the production process.
