[0019] It should be noted that there seems to be a formatting issue with the original text where the tag [[ID=?]] is used. It should probably be a normal sequential ID like the others. Also, the translation is done based on the best understanding of the context, but some terms might need further adjustment depending on the specific technical field and accuracy requirements.Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a double-cone dryer with an automatic cleaning function includes a connecting seat 1. The inner side of the connecting seat 1 is rotatably connected to a dryer outer shell 3 through a rotating shaft 2. A cleaning mechanism is installed on the outer wall of the dryer outer shell 3. The cleaning mechanism in the operating state is used to clean the inner cavity of the dryer inner shell 12. The dryer inner shell 12 is located on the inner wall of the dryer outer shell 3, and there is a jacket 13 between the outer wall of the dryer inner shell 12 and the inner wall of the dryer outer shell 3; a driving mechanism for driving one rotating shaft 2 to rotate is installed in the cavity inside the connecting seat 1. The driving mechanism is used to drive the rotating shaft 2 to perform circumferential rotation. The rotating one rotating shaft 2 is used to drive the dryer outer shell 3, the dryer inner shell 12, the jacket 13 and the other rotating shaft 2 to rotate.

[0021] In this embodiment: when drying powdery and granular materials, the materials are poured into the dryer inner shell 12 through the input port, and then the cover plate is sealed in the input port with bolts. Then the driving mechanism is started. The driving mechanism drives one rotating shaft 2 to rotate. The rotating shaft 2 drives the dryer outer shell 3 to rotate. The dryer outer shell 3 drives the other rotating shaft 2 to rotate. After drying is completed, the end cover of the output port of the dryer inner shell 12 is opened, and the dried materials are discharged through the output port;

[0022] When drying another material, the dryer inner shell 12 is filled with cleaning liquid (such as: water and the corresponding cleaning liquid) through the input port. Then the ultrasonic generator is connected to the cleaning mechanism, and the cleaning mechanism operates to perform sufficient ultrasonic cleaning on the inner wall of the dryer inner shell 12.

[0023] Please pay special attention to Figure 1 , the centers of both rotating shafts 2 are hollow structures. A medium input pipe 4 and a medium output pipe 5 that penetrate the center of the rotating shaft 2 and are connected to the inner cavity of the jacket 13 are arranged outside the connecting seat 1. The medium input pipe 4 is rotatably connected to the center of one rotating shaft 2, and the medium output pipe 5 is rotatably connected to the center of the other rotating shaft 2.

[0024] In this embodiment: The high-temperature medium (e.g., high-temperature steam) enters the jacket 13 through the medium input pipe 4. The high-temperature medium entering the jacket 13 heats the inner shell 12 of the dryer, thereby realizing the drying function. The high-temperature medium after heat exchange is discharged through the medium output pipe 5, and then heated again, and circulates to heat the inner shell 12 of the dryer. Since the medium input pipe 4 and the medium output pipe 5 are respectively rotatably connected to the two rotating shafts 2, the device in the rotating state will not affect the transmission and heat exchange of the high-temperature medium.

[0025] Please refer particularly to Figure 3 , the driving mechanism includes a driving motor 11 installed outside the connecting seat 1. The output end of the driving motor 11 penetrates into the inner cavity of the connecting seat 1, and the output end of the driving motor 11 is rotatably connected to the connecting seat 1 through a bearing. The output end of the driving motor 11 is connected with a driving gear 15, and the outer circumference of the driving gear 15 is engaged with a driven gear 14. The driven gear 14 is press-fitted on the outer circumference of a jacket 13.

[0026] In this embodiment: By starting the driving motor 11, the driving motor 11 drives the driving gear 15 to rotate. The driving gear 15 rotates to drive the driven gear 14 to rotate. The driven gear 14 drives the dryer to rotate through a rotating shaft 2, realizing uniform heating and drying of powder and granular materials.

[0027] Please refer particularly to Figure 1 and Figure 2 , the cleaning mechanism includes a protrusion 6 integrally formed on the outer wall of the dryer housing 3. The protrusion 6 protrudes outward. A connecting port 7 protruding outward is formed at the center of the protrusion 6, and an electric connection box 9 is installed at a non-center position of the protrusion 6. An electric socket 10 penetrating to the outside of the electric connection box 9 is installed on the PCB board inside the electric connection box 9. The cleaning mechanism further includes a piezoelectric transducer 8 electrically connected to the PCB board inside the electric connection box 9. The flange part on the piezoelectric transducer 8 is connected to the flange part of the connecting port 7, and a sealing member is provided at the connection position of the two flange parts; the piezoelectric transducer 8 is located at a position below the flange part and penetrates into the inner cavity of the jacket 13 through the connecting port 7, and one end of the piezoelectric transducer 8 is in contact with the outer wall of the inner shell 12 of the dryer.

[0028] In this embodiment: When cleaning the inner shell 12 of the dryer, the device is in a power-off state at this time. After filling the inner shell 12 of the dryer with a mixture of water and cleaning liquid, the electric plug of the ultrasonic generator is inserted into the electric socket 10 at this time. At this time, the piezoelectric transducer 8 generates high-frequency mechanical vibrations, and the ultrasonic waves are radiated into the cleaning liquid inside the dryer through the inner shell 12 of the dryer. Due to the radiation of the ultrasonic waves, the microbubbles in the liquid of the inner shell 12 of the dryer can maintain vibrations under the action of the sound waves, thereby achieving effective automatic cleaning.

[0029] Please refer to the figure with emphasis. The electrical socket 10 is connected to the ultrasonic generator through a wire.

[0030] In this embodiment: The ultrasonic generator converts electrical energy into a high-frequency alternating current signal that matches the piezoelectric transducer 8.

[0031] Please refer to with emphasis Figure 1 , covers are installed on the input and output ports of the inner shell 12 of the dryer.

[0032] In this embodiment: The cover can open or close the input and output ports.

[0033] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
