[0002] The gas phase coating furnace is a special equipment for gas phase coating of multiphase materials. It is widely used in the production process of battery materials, such as the preparation of silicon-coated carbon or carbon-coated silicon.

[0003] In the related technology, commonly used gas phase coating equipment includes fluidized bed furnace and tilting rotary continuous furnace. Since the airflow control of fluidized bed furnace is complicated and difficult to adjust accurately, it has the disadvantages of large gas consumption, high energy consumption and low output during use;

[0004] Although the inclined rotary continuous furnace has improved the production problem to a certain extent, it is easy to produce uneven heat distribution and gas flow inside the furnace during the movement of materials. There is still a problem of high gas consumption, low product yield and poor coating uniformity. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a rotary gas-phase coating intermittent furnace, which has high raw gas utilization rate and low energy consumption.

[0006] According to the first aspect of the utility model, a rotary gas-phase coating intermittent furnace comprises a furnace, rollers are arranged on both sides of the furnace, a furnace core is arranged in the furnace, the furnace core rotates on the rollers, an air inlet pipe and an exhaust pipe are passed through the furnace core; and a material lifting plate is arranged on the inner wall of the furnace core.

[0007] According to a rotary gas-phase coating intermittent furnace of the present utility model, at least the following

[0008] Beneficial effects:

[0009] By setting a lifting plate on the inner wall of the furnace, the powder can be rolled and fully and evenly contacted with the gas phase cracking products, thus significantly improving the uniformity of the coating layer; by optimizing the design of the airflow path and the filtration system, the emission of dilution gas and incomplete cracking gas is effectively reduced, the gas utilization rate is improved, and the gas consumption and energy consumption in the entire coating process are reduced, saving production costs. The rotation of the furnace on the roller allows the material to be fully turned and evenly heated in the furnace, avoiding material accumulation and uneven heat distribution, and improving the actual yield and production efficiency of the product.

[0010] According to some embodiments of the utility model, a filter is provided at one end of the exhaust pipe close to the air inlet pipe. The setting of the filter ensures that the gas discharged from the exhaust pipe is filtered, thereby reducing the emission of harmful gases and improving the safety and cleanliness of the production environment.

[0011] According to some embodiments of the utility model, both ends of the furnace are equipped with openable and closable furnace doors, which greatly facilitates the loading and unloading of materials, improves the flexibility and efficiency of production, and also facilitates the cleaning and maintenance of the equipment, reducing downtime.

[0012] According to some embodiments of the utility model, the portion of the air inlet pipe inserted into the furnace is provided with a plurality of diversion holes, so that the gas-phase precursor can be more evenly distributed in the working temperature zone of the material, ensuring that the gas-phase cracking products are evenly deposited on the surface of the material, improving the uniformity of the coating layer, and optimizing product performance.
