[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example 1

[0024] like Figure 1-4 As shown, the utility model provides a centrifugal spray drying device, including a drying cylinder 1, a top plate 11 is fixedly connected to the inner side of the top of the drying cylinder 1, a driving motor 2 is fixedly installed on the top of the top plate 11, a drying mechanism 4 is installed at the bottom of the top plate 11, and a conveying pipe 3 is installed above the top plate 11;

[0025] The drying mechanism 4 includes a rotating sleeve 43 and a gear ring 44. The top of the gear ring 44 is fixedly connected to the bottom of the top plate 11. Two first fixed plates 46 are symmetrically fixedly connected to the outer surface of the bottom end of the rotating sleeve 43, and two second fixed plates 47 are symmetrically fixedly connected to the outer surface of the bottom end of the rotating sleeve 43. One end of the first fixed plate 46 is rotatably connected to a rotating rod 45. A pinion 452 is fixedly connected to the outer surface of the top end of the rotating rod 45, and a cleaning brush 451 is fixedly connected to the outer surface of the bottom end of the rotating rod 45. The pinion 452 is meshingly connected to the gear ring 44.

[0026] The specific configuration and function of this embodiment are described in detail below. When the driving motor 2 is started, it drives the active bevel gear 41 to start rotating. The meshing design of the active bevel gear 41 and the driven bevel gear 42 enables the rotation of the active bevel gear 41 to be smoothly transmitted to the driven bevel gear 42. As the driven bevel gear 42 rotates, the rotating sleeve 43 also rotates. This design ensures that the rotating sleeve 43, the first fixing plate 46 and the second fixing plate 47 can rotate as a whole.

[0027] When the first fixed plate 46 starts to rotate, it drives the rotating rod 45 connected thereto to rotate together. The pinion 452 at the top of the rotating rod 45, due to the meshing relationship with the gear ring 44, will rotate around the rotating sleeve 43. In this process, the pinion 452 will be acted upon by the gear ring 44, thereby starting its own rotational motion.

[0028] As the pinion 452 rotates, the rotating rod 45 also rotates accordingly. Since the cleaning brush 451 is fixed on the rotating rod 45, it rotates together with the rotation of the rotating rod 45. The design of the cleaning brush 451 enables it to rotate while rotating, and this composite motion enables the cleaning brush 451 to clean the inner wall of the drying cylinder 1 more effectively.

[0029] Through the movement and rotation of the cleaning brush 451, the acer truncatum seed oil atomized material on the inner wall of the drying cylinder 1 is effectively cleaned, thereby preventing them from adhering to the inner wall of the drying cylinder 1. This design not only ensures the smooth progress of the drying process, but also effectively prevents the coking phenomenon caused by long-term drying. This not only improves the quality of the acer truncatum seed oil, but also extends the service life of the equipment and reduces maintenance costs. Example 2

[0030] like Figure 2 and Figure 3 As shown, the delivery pipe 3 is fixedly connected to the inner wall of the rotating sleeve 43, and the bottom end of the delivery pipe 3 passes through the rotating sleeve 43. The bottom of the delivery pipe 3 is fixedly connected to the spray pipe 32, and the inner side of the spray pipe 32 is fixedly connected to the atomizing nozzle 33. The top of the rotating sleeve 43 passes through the top plate 11, and the rotating sleeve 43 is rotatably connected to the top plate 11. The outer surface of the top of the rotating sleeve 43 is fixedly connected to the driven bevel gear 42, and the driven bevel gear 41 is meshed and connected to one side of the driven bevel gear 42. The top of the delivery pipe 3 is rotatably connected to the rotating connector 31, and the driven bevel gear 42 is fixedly connected to the output end of the driving motor 2. The cleaning brush 451 is attached to the inner wall of the drying cylinder 1, and a plurality of heating lamp heads 471 are fixedly connected to the bottom of the second fixed plate 47.

[0031] The effect achieved by the entire embodiment is that when the rotating sleeve 43 starts to rotate, it will be further transmitted to the delivery pipe 3 connected thereto. This mechanical linkage design ensures that the delivery pipe 3 can rotate synchronously with the rotation of the rotating sleeve 43. As a channel for delivering the Acer truncatum seed oil, the delivery pipe 3 is not limited to itself in rotation, but will also drive the spray pipe 32 connected thereto to rotate together through the continuity of its internal structure.

[0032] During the rotation of the spray tube 32, due to the effect of centrifugal force, the maple seed oil will form finer droplets when sprayed through the spray tube 32 and quickly drift away. This atomization spraying method not only increases the contact area between the oil droplets and the air, improves the drying efficiency, but also enables the oil droplets to be more evenly distributed inside the drying cylinder 1, thereby further ensuring the uniformity of the drying effect.

[0033] At the same time, the drying cylinder 1 is also equipped with a heating lamp 471 for heating. To ensure that the temperature inside the drying cylinder 1 can be kept uniform. During the atomization spraying and drying of the Acer truncatum seed oil, the heating lamp 471 can provide a continuous and stable heat source, so that the temperature inside the drying cylinder 1 is always kept within a suitable range. This temperature control not only avoids the problem of uneven drying caused by temperature difference, but also ensures that the Acer truncatum seed oil will not be coked or have other adverse effects due to excessive temperature during the drying process.

[0034] The use method and working principle of the device: When the maple seed oil is dried, the maple seed oil is firstly connected to the external pipeline through the rotating connector 31 to realize the delivery of the maple seed oil. The oil then enters the delivery pipe 3 and is delivered to the spray pipe 32 through the delivery pipe 3. After that, the maple seed oil is atomized and sprayed into the drying cylinder 1 through the action of the atomizing nozzle 33.

[0035] During the atomization drying process, the driving motor 2 is started, driving the active bevel gear 41 to rotate. The active bevel gear 41 drives the driven bevel gear 42 to rotate through the force, thereby driving the entire rotating sleeve 43, the first fixed plate 46 and the second fixed plate 47 to rotate together. As the first fixed plate 46 rotates, the rotating rod 45 also rotates synchronously. This causes the pinion 452 at the top of the rotating rod 45 to begin to perform circular motion with the rotating sleeve 43 as the center. In this process, the pinion 452 begins to rotate due to the force of the gear ring 44. Due to the rotation of the pinion 452, the rotating rod 45 drives the cleaning brush 451 to rotate together. The cleaning brush 451 effectively cleans the inner wall of the drying cylinder 1 through its activity and rotation, prevents the Acer truncatum seed oil from adhering to the inner wall after atomization, and prevents the coking phenomenon caused by long-term drying.

[0036] In addition, when the rotating sleeve 43 rotates, it also drives the delivery pipe 3 and the spray pipe 32 connected thereto to rotate together. This rotation utilizes centrifugal force to allow the maple seed oil to quickly disperse after atomization and spraying, thereby improving the drying efficiency inside the drying cylinder 1. At the same time, during the drying process, the heating lamp head 471 provides uniform heating to ensure uniform temperature distribution inside the drying cylinder 1, thereby avoiding uneven drying caused by temperature differences.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
