[0016] 3. Beneficial effects

[0017] (1) The present invention uses the negative pressure generated by the vacuum pump to extract the air contained in the ultrafine powder material during the packaging process, so that the packaging bag is in a vacuum state, thereby facilitating handling, packaging, stacking and transportation, and completely improving the production environment, truly achieving dust-free and environmental protection.

[0019] (3) The present invention is equipped with an air pipe filter to prevent some ultrafine particles from being drawn into the air extraction pipe when the air mixed in the ultrafine powder material is extracted, and finally entering the air extraction buffer tank through the hose, causing damage to the equipment. After the air extraction is completed, the valves of each air path are closed, and then the valve of the backflush system is opened to backflush the pipe network, thereby protecting the air pipe filter from being blocked by ultrafine particles.

[0020] (4) The present invention drains the ultrafine powder material by installing a drainage plate to prevent the ultrafine powder material from dust flying and leaking. The support frame further supports the exhaust pipe to prevent the exhaust pipe from tilting and contacting the inside of the feed tank when moving. A sealing ring is provided at the opening of the feed tank to ensure the sealing of the feed tank.
