[0028] Working principle: The device adopts a closed-loop micro-positive pressure conveying system. In this system, the powder passes through the nitrogen micro-positive pressure system. After the powder is captured, it is transported in a closed-loop reaction device. The lost nitrogen is replenished by the nitrogen micro-positive pressure system. This system includes: micro-positive pressure closed-loop conveying system 1, nitrogen closed-loop recovery unit 2, electrical control unit 3, etc. Using this solution, not only can the material be transported normally, but also the nitrogen consumption can be saved.

Low risk level, improve economic benefits, reduce environmental protection costs. In addition, after long-term use, the filter plate 74 in the filter A7 can be disassembled and cleaned. Pull the T-shaped rod 76 to the opposite side. In addition, the extension of the spring 761 can drive the T-shaped rod 76 to move in the opposite direction and move away from the inner cavity of the adjacent slots. At this time, the sealing cover 72 can be released. Pulling the sealing cover 72 upward can drive the filter plate 74 away from the inner cavity of the filter A7 to achieve its disassembly. After cleaning, the reverse operation can be performed to re-clamp and fix the filter plate 74.
