[0030] 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 different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] An automatic feeding device for RPC particle production, such as Figure 1-Figure 6 As shown, it includes a support frame, a rotating barrel 1, an air-cooled stirring assembly 2 and a stirring shaft 3 for unloading. The support frame is provided with an air-cooled stirring assembly 2, a cover 4, a mounting ring 10, a second drive motor 14 and a tray 6 in sequence along the axial direction of the rotating barrel 1. The rotating barrel 1 is movably mounted on the support frame through the mounting ring 10. The cover 4 is movably mounted on the top of the rotating barrel 1. The rotating barrel 1 is located between the cover 4 and the tray 6. The stirring end of the air-cooled stirring assembly 2 passes through the cover 4, and the penetrating portion of the air-cooled stirring assembly 2 is located in the rotating barrel 1. The unloading stirring shaft 3 passes through the air-cooled stirring assembly 2 and the cover 4, and the penetrating portion of the unloading stirring shaft 3 is movably connected to the inside of the rotating barrel 1. The second drive motor 14 is connected to the rotating barrel 1 to drive the rotating barrel 1 to rotate. The rotating barrel 1 can rotate, and an electric valve 11 is installed on the discharge port of the rotating barrel 1. The cover 4 is overlapped on the rotating barrel 1 in a concave shape. The cover 4 is movably connected to the rotating barrel 1 through a lifting cylinder 5. The lifting cylinder 5 is relatively installed on the support frame. The cover 4 can be lifted for easy loading. A through hole compatible with the air-cooled stirring assembly 2 and the unloading stirring assembly is opened on the cover 4. It is not connected to the rotating barrel 1 to avoid the cover 4 from moving when the rotating barrel 1 rotates. The tray 6 is compatible with the bottom of the rotating barrel 1, and the discharge port of the rotating barrel 1 passes through the tray 6, and the inner wall of the tray 6 is provided with a lubricating layer. Balls are provided in the mounting ring 10 to reduce friction during rotation and provide lifting force to ensure the service life and stability of the device.

[0032] The combination of the air-cooled stirring component 2 and the unloading stirring shaft 3 can significantly improve the mixing efficiency of the materials in the rotating barrel 1 by working together. The air-cooled stirring component 2 can not only promote the uniform mixing of the materials through airflow, but also control the temperature during the mixing process through cooling to prevent the materials from overheating or deterioration. The unloading stirring shaft 3 further enhances the mixing effect to ensure that the materials can be fully stirred and mixed at all levels.

[0033] The air-cooled stirring assembly 2 includes an air cooler 21, a fixed disk 22 and a plurality of fixed shafts 23. The air cooler 21 pipeline is connected to the fixed disk 22. The plurality of fixed shafts 23 are arranged in a ring shape with the axis of the fixed disk 22 as the center. The fixed disk 22 and the plurality of fixed shafts 23 are both hollow. The portion of the fixed shaft 23 located below the cover 4 is provided with a plurality of air holes 7 and a brush strip 8. The side of the fixed shaft 23 away from the inner wall of the rotating barrel 1 is provided with a plurality of air holes 7. The side of the fixed shaft close to the inside of the rotating barrel 1 is provided with a brush strip 8. The number of the fixed shafts 23 is preferably four, which not only ensures the uniform distribution of the airflow, but also ensures that the brush strip 8 can fully cover the inner wall of the rotating barrel 1 and is close to the inner wall of the rotating barrel 1. When the rotating barrel 1 rotates independently, the inner wall is cleaned by the fixed brush strip 8 to avoid adhesion. The air-cooled stirring assembly 2 is in a fixed state and will not rotate with the rotation of the rotating barrel 1.

[0034] The fixed disk 22 is fixedly installed between the support frames, the air cooler 21 is fixedly installed on the support frames, and filter screens are provided on the several air holes 7. The unloading stirring shaft 3 passes through the axial position of the fixed disk 22. The air flow provided by the air cooler 21 passes through the hollow parts of the fixed disk 22 and the fixed shaft 23, and finally ejects from the air holes 7 on the fixed shaft 23, directly acting on the material, thereby realizing rapid cooling of the material and the inside of the device. At the same time, the injection of the air flow also helps to stir the material, promotes the uniform mixing of the material, and reduces the reflux blockage of the material through the screen.

[0035] The rotating barrel 1 is cylindrical as a whole, and the discharging part is truncated cone-shaped. The fixed shaft 23 extends only to the end of the cylinder. A large spiral bevel gear wheel 12 is installed on the outer surface of the rotating barrel 1. A small spiral bevel gear wheel 13 matched with the large spiral bevel gear wheel 12 is installed on the output end of the second drive motor 14. The second drive motor 14 drives the large spiral bevel gear wheel 12 through the small spiral bevel gear wheel 13. The cam 9 and the large spiral bevel gear wheel 12 are both installed on a cylindrical part of the rotating barrel 1. The meshing design of the spiral bevel gear can effectively prevent slipping and maintain a stable speed even when the load changes, thereby ensuring continuous material transmission. The bottom of the rotating barrel 1 is overlapped on the tray 6. A cam 9 is provided on the outer surface of the rotating barrel 1. The rotating barrel 1 is movably mounted on the mounting ring 10 through the cam 9.

[0036] The material discharging stirring shaft 3 comprises a first motor 31, a stirring shaft 32 and a plurality of stirring fans 33. The first motor 31 is connected to the plurality of stirring fans 33 through the stirring shaft 32. The first motor 31 is located above the fixed disk 22. The stirring shaft 32 passes through the fixed disk 22 and the cover 4. A spiral conveying knife is provided at the end of the stirring shaft 32. The spiral conveying knife is located above the electric valve 11. The first motor 31 is installed above the fixed disk 22. A plurality of stirring fans 33 are installed in an array on the stirring shaft 32. The number of stirring fans 33 is preferably four. The fixed shaft 23 of the air-cooled stirring assembly 2 surrounds the stirring shaft 32 in an annular manner. Three stirring fans 33 are located in the cylindrical portion of the rotating barrel 1 and are surrounded by the fixed shaft 23. The air-cooled stirring assembly 2 not only provides additional support for the stirring shaft 32, but also optimizes the heat dissipation effect and prolongs the service life of the equipment. Another stirring fan 33 is located at the material discharging portion of the truncated table and is adapted thereto to sweep the mixed material to the spiral conveying knife, and push the material forward while stirring, thereby improving the efficiency and smoothness of material discharging, and discharging is performed.

The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.

[0038] Working principle: the staff starts the lifting cylinder 5 to lift the cover 4, loads the materials and mixes the raw materials to prepare for stirring and mixing. After the loading is completed, the lifting cylinder 5 descends to drive the cover 4 to seal the rotating barrel 1, and further starts the second drive motor 14 to drive the rotating barrel 1 to rotate. At this time, the cold air fan 21 is started to cool the inside of the rotating barrel 1 and drive better mixing through the airflow. At this time, the material unloading stirring shaft 3 is in a stopped state. Due to the independent rotation of the rotating barrel 1, the material unloading stirring shaft 3 is also in a stirring state;

[0039] When the mixing is completed and the material needs to be discharged, the rotating barrel 1 is stopped, and the first motor 31 is started to drive the mixing shaft 32 to discharge the material. The material is swept to the screw conveying knife through the lowest mixing fan 33, and the electric valve 11 at the discharge port is opened to discharge the material.
