Pneumatic connector for continuously moving grains - has time corrected filling and conveying processes with opening and closing forwarding chambers

摘要

The powder or grains (13) pass from a pressureless container (1) with outlet pipe (2) into an opened forwarding chamber (3) which when full is closed by a sealing element (4) shutting off the filler opening (5). Parallel to the filling process the forwarding chamber (3a) is biased by air (11) which sends the powder into the pipe (9). On reaching a certain minimum mark the sealing element (6a) closes the forwarding chamber (3a) whilst the sealing element (6) of the lower forwarding chamber (31) is opened, the forwarding chamber (3) is pressurised and the powder is moved into the pipeline (9). USE/ADVANTAGE - Continuous grain moving device. Expensive mechanical parts requiring maintenance and replacement are avoided.
