[0027] The working principle of the present invention is as follows: All the electrical components in the present invention are triggered to operate by the controller. In some steps of powder metallurgy processing, the metallurgical robotic arm 20 needs to work in a powder environment, such as powder handling work during powder mixing and powder transfer work during powder screening. Multiple dust sensors can be suspended according to the movement path of the metallurgical robotic arm 20. The powder sensors transmit the dust information to the controller. The controller receives the dust information and triggers the cyclic dust prevention and heat dissipation device 30, the joint dust prevention device 40, and the swinging dust removal device 50 to work after analysis. When the cyclic dust prevention and heat dissipation device 30 works, electrical components required for the operation of the metallurgical robotic arm 20 are installed in the base 201. When the electrical components work, heat dissipation treatment is required. Fans are provided in both the air inlet pipe 301 and the air outlet pipe 302. The air flow enters the outer shell of the base 201 through the air inlet pipe 301, and the gas after heat exchange is discharged through the air outlet pipe 302. When the metallurgical robotic arm 20 is in a dust environment, the driving component 33 drives the rotating filter screen ring 32 to continuously rotate. The rotating filter screen ring 32 at the position of the air inlet pipe 301 is continuously updated to ensure the dust filtering effect. When the rotating filter screen ring 32 rotates to the air outlet pipe 302, the gas discharged from the air outlet pipe 302 can also blow and clean the rotating filter screen ring 32. When the driving component 33 works, the execution end of the driving motor 332 drives the rotating filter screen ring 32 to rotate through the first gear 333 and the tooth wall ring 331. At the same time, the rotation of the tooth wall ring 331 drives the second gear 335 and the cleaning roller 334 to rotate. The cleaning roller 334 can clean and beat the rotating filter screen ring 32 to facilitate the removal of dust on the rotating filter screen ring 32; When the rotating filter screen ring 32 passes through the cleaning component 34, the cleaning component 34 can remove the dust on the rotating filter screen ring 32. When the cleaning component 34 works, the air source system is turned on, and the gas is discharged through the positive pressure air flow pipe, the first air source pipe 343 with the valve opened, and the blowing pipe 341 to blow the rotating filter screen ring 32 with air flow.
