The vacuum feeder forms a negative pressure air flow under the vacuum. Under the action of this air flow, the conveyed material instantly transfers the bulk material to another container through the suction hose or tube. Since the material is always in a vacuum state during the transportation process, even if the pipeline leaks, the material will not be leaked into the surrounding environment.
A: The vacuum pump (1) generates vacuum through the separation container of the vacuum conveying equipment. The material is sucked from the feed port (3) through the suction hose and the suction port (2).
B: Separate air and materials in the filter bin (4) of the separation container and collect the materials in the bin. The cyclone (5) prevents fine powder from entering the filter to increase the efficiency of the filter.
C: When the silo is full of materials, the vacuum pump is automatically shut down, and the pressure in the conveying equipment reaches equilibrium. The discharge valve is opened, and the material flows out through the discharge port (6) and falls directly into the storage container (7).
D: When discharging, the filter cabin is automatically cleaned by the recoil airbag. Its special vibrator can assist the blanking to improve the efficiency of conveying viscous materials.
E: The discharge cabin is closed, and the whole conveying process is started again.
F: Vacuum feeder is a new type of energy-saving and environment-friendly powder conveying equipment.
