[0034] The working principle of the present invention is as follows: The raw material silo is filled with powder to be ground. The mixing fan is started to supply air through the air supply pipe, and the powder is sent into the tank of the grinding mechanism through the feed pipe. After grinding in the tank for a certain period of time, the ground powder is transported to the first-level cyclone separator through the discharge pipe for the first preliminary separation. The powder that does not meet the requirements after separation is returned to the tank of the grinding mechanism through the return pipe. The powder that meets the preliminary requirements after separation enters the silo wall vibrating screen through the return pipe under the action of wind. The powder vibrates through the silo wall vibrating screen to prevent the material from accumulating in the silo wall and ensure that the material can slide smoothly along the silo wall to avoid blockage. The powder can also be separated and screened again. The powder after passing the silo wall vibrating screen enters the secondary cyclone separator through the drop pipe for the final separation of the powder. The powder that meets the requirements enters the storage silo through the storage pipe, and the powder that does not meet the requirements enters the return pipe again through the separation pipe for recirculation until it meets the requirements.

[0035] The planetary grinding blade assembly of the present invention rotates in multiple directions at high speed within the tank body, forming an efficient mechanochemical force, which significantly improves the grinding efficiency of the powder. During the grinding process, the material particle size, uniformity and chemical modification can be precisely controlled by adjusting the speed of the drive motor and controlling the atmosphere through the air inlet / outlet system, thereby improving product quality. The feeding and discharging mechanism integrates multiple modules such as a mixing fan, a feeding assembly, a return assembly, a discharging assembly and a mixed return assembly to realize automated feeding, grinding, separation, return, discharging and storage processes. Intelligent control components such as a vacuum switching valve, a feeding rotary valve, a discharging intelligent control damper and a separation intelligent control damper are provided to facilitate precise control of the entire process, reduce manual intervention and improve production continuity and stability. The tank cover and the tank support sleeve shaft are detachably connected, making it easy to open the tank for internal cleaning or replacement of components such as the grinding blade. A spacer is set between the planetary grinding blade assembly and the rotating shaft, and is fixed by a shaft end cover, making it easy to disassemble and repair. The design of the spring and bearing structure enhances the stability and shock absorption performance of the rotating system, extending the service life of the equipment. The use of the silo wall vibrating screen effectively prevents powder from accumulating on the inner wall of the equipment, ensuring smooth material flow. It also has a screening function, separating large particles from qualified fine powder, and returning the material through the return pipe to the primary cyclone separator for re-grinding to ensure the consistency of the final product particle size. The air inlet and outlet pipes are connected to the condenser, mixing fan and other devices, which not only helps to regulate the gas environment in the grinding chamber, but also effectively collects dust and reduces environmental pollution. The mixed return component realizes the recycling of materials, improves the utilization rate of raw materials, reduces energy consumption and waste. The return component and mixed return component can be selected according to different process requirements to enhance the flexibility and applicability of the equipment. Multiple windows make it easy to observe the material status, detect abnormal conditions in time, and ensure the safe operation of the equipment.

[0036] The detachable connection between the tank cover and the tank support sleeve makes cleaning and maintenance more convenient, and also facilitates the replacement or adjustment of internal components. The design of the movable connection between the grinding blade assembly and the tank support sleeve ensures that during operation, the blade can automatically adjust its position or angle according to the state of the material, thereby improving grinding efficiency and uniformity. The pressure gauge on the tank cover can monitor and adjust the pressure in the tank during operation, preventing safety hazards caused by excessive pressure and ensuring operational safety. The presence of the air inlet and outlet pipes means that the device can operate in different gas environments, such as processing air-sensitive materials under the protection of inert gas, or promoting certain chemical reactions by introducing specific gases, which greatly improves the controllability and applicability of the device. The detachable connection between the rotating blade and the rotating shaft allows the blade to be quickly and easily replaced or cleaned, reducing the time and difficulty of equipment maintenance. The spacer design can provide a protective layer between the rotating blade and the rotating shaft, reducing wear between the two, thereby extending the overall service life of the component. The spacer can also adjust the position of the rotating blade to ensure it is in optimal working condition. The detachable connection between the shaft end cover and the rotating shaft not only facilitates installation and removal, but also effectively prevents safety accidents caused by loose rotating parts during operation, thereby improving the safety of equipment operation. The use of bearings can significantly reduce friction during rotation of the rotating shaft, making the rotation smoother and more stable. This not only helps improve grinding efficiency, but also reduces noise and vibration during equipment operation. The spring design can act as a buffer and shock absorber during operation, effectively absorbing the vibration generated by the rotating shaft during operation and protecting the entire mechanical system from impact damage. This is very beneficial for extending the service life of the equipment. The presence of the spring allows a certain amount of elastic deformation space for the rotating shaft, allowing it to automatically adjust the rotation force and angle according to the resistance of the material, thereby achieving a more refined and uniform grinding effect. Since the spring and bearing are both placed in the tank support sleeve shaft, this compact design helps to maintain the precise position of the rotating shaft, prevent offset or misalignment caused by external factors, and improve operational accuracy.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
