[0023] like Figures 1 to 4As shown, a high-efficiency and energy-saving drying device includes a fixed base plate 1 and a drying component 3. A support frame 2 is installed on the upper surface of the fixed base plate 1. The drying component 3 is arranged on the inner side of the support frame 2, and the drying component 3 includes a drying tank 301, a discharge port 302, a heater 303, a connecting pipe 304, an exhaust pipe 305, a recovery box 306, an exhaust port 307 and a filter screen 308. The drying tank 301 is arranged on the inner side of the upper end of the support frame 2, and the discharge port 302 is installed on the lower right end of the drying tank 301. The heating machine 303 is arranged on the left side of the upper surface of the fixed base plate 1, and the front surface of the heating machine 303 is connected to the connecting pipe 304, and the end of the connecting pipe 304 away from the heating machine 303 is connected to the lower left end of the drying tank 301, the exhaust pipe 305 is connected to the upper right end of the drying tank 301, and the recovery box 306 is installed on the end of the exhaust pipe 305 away from the drying tank 301.

[0024] The specific operation is as follows. When in use, after the heater 303 is turned on, the hot air is transported to the inside of the drying tank 301 through the connecting pipe 304 to dry the dry powder in the drying tank 301. During the drying process, the hot air in the drying tank 301 will continue to be discharged through the exhaust pipe 305 to ensure that the hot air in the drying tank 301 continues to flow and improve the drying efficiency. The exhausted hot air is discharged into the recovery box 306 through the exhaust pipe 305 for recycling. At the same time, the dry powder preliminarily dried by the drying tank 301 will also fall into the recovery inner basket 401 in the recovery box 306 through the discharge port 302 to further dry the dry powder. At the same time, the gas is discharged through the exhaust port 307. The filter 308 can prevent the dry powder from being discharged during exhaust.

[0025] Please refer to Figure 3 , an exhaust port 307 is installed at the front end of the upper surface of the recovery box 306, and a filter screen 308 is arranged inside the exhaust port 307, a recovery component 4 for recovering dry powder is arranged inside the recovery box 306, and the recovery component 4 includes a recovery inner basket 401, a coarse-pore filter screen 402, a fine-pore filter screen 403, an auxiliary handle 404 and a first vibration motor 405, the recovery inner basket 401 is slidably connected to the inside of the recovery box 306, and a coarse-pore filter screen 402 is installed at the upper end of the recovery inner basket 401, and a fine-pore filter screen 403 is arranged below the coarse-pore filter screen 402, an auxiliary handle 404 is installed at the upper end of the front surface of the recovery inner basket 401, and a first vibration motor 405 is arranged at the lower end of the front surface of the recovery inner basket 401;

[0026] The specific operation is as follows. When in use, the dry powder after preliminary drying falls into the recovery inner basket 401, and the first vibration motor 405 is started, so that the first vibration motor 405 drives the recovery inner basket 401 to vibrate as a whole, and then the coarse-pore filter 402 intercepts and filters the dry powder blocks that are not completely dried and agglomerated. After the dry powder blocks are completely dried, they will disperse and fall onto the fine-pore filter 403. After continuous vibration, the fine-pore filter 403 will filter and screen the larger particles in the dry powder to ensure the quality of the finished product until the dry powder is thoroughly screened. The recovery inner basket 401 is pulled by the auxiliary handle 404 to slide forward along the inner side of the recovery box 306 to facilitate further processing of the dry powder.

[0027] Please refer to Figure 2 and Figure 4 A protective cover 5 is installed on the left surface of the drying tank 301, and a feed hopper 6 is arranged on the upper side of the left end of the drying tank 301. A servo motor 7 is installed inside the protective cover 5, and the output end of the servo motor 7 is connected to a material conveying auger 8 through a coupling. A fixed plate 9 is installed on the rear side of the upper surface of the feed hopper 6, and a second vibration motor 10 is arranged on the upper surface of the fixed plate 9. A sealing plate 11 is rotatably connected to the front side of the fixed plate 9;

[0028] The specific operation is as follows. When in use, wet dry powder raw materials are put into the drying tank 301 through the feed hopper 6, and the second vibration motor 10 is started at the same time to prevent the wet materials from adhering to the surface of the feed hopper 6. The servo motor 7 is started to drive the servo motor 7 to rotate the material conveying auger 8, so that the material conveying auger 8 drives the material to the right end and dries it during the transmission process.

[0029] In summary, if Figures 1 to 4As shown, when the efficient and energy-saving drying device is used, first, wet dry powder raw materials are put into the drying tank 301 through the feed hopper 6, and the second vibration motor 10 is started at the same time to prevent the wet materials from adhering to the surface of the feed hopper 6, and the servo motor 7 is started to make the servo motor 7 drive the material conveying auger 8 to rotate, so that the material conveying auger 8 drives the materials to be conveyed to the right end, and after the heater 303 is turned on, the hot air is transported to the inside of the drying tank 301 through the connecting pipe 304 to dry the dry powder in the drying tank 301. During the drying process, the hot air in the drying tank 301 will continue to be discharged through the exhaust pipe 305 to ensure that the hot air in the drying tank 301 continues to flow and improve the drying efficiency. The exhausted hot air is discharged into the recovery box 306 through the exhaust pipe 305 for recycling. At the same time, the dry powder that has been preliminarily dried in the drying tank 301 will also be discharged through the discharge port 30 2 falls into the recovery inner basket 401 in the recovery box 306, and the dry powder is further dried. At the same time, the gas is discharged through the exhaust port 307. The filter screen 308 can prevent the dry powder from being discharged during the exhaust. In the secondary drying process, the first vibration motor 405 is started to drive the recovery inner basket 401 to vibrate as a whole, so that the coarse-pore filter screen 402 intercepts and filters the dry powder blocks that are not completely dried and agglomerated. After the dry powder blocks are completely dried, they will disperse and fall on the fine-pore filter screen 403. After continuous vibration, the fine-pore filter screen 403 will filter and screen the larger particles in the dry powder to ensure the quality of the finished product. Until the dry powder is thoroughly screened, the recovery inner basket 401 is pulled by the auxiliary handle 404 to slide forward along the inner side of the recovery box 306, so as to facilitate further processing of the dry powder.
