Title: Clogged position specifying method for powder air stream transporting pipe
Inventor: OTAKA MATSUO
IPC: B65G53/66
Filed: 1989-04-12
Abstract: PURPOSE:To simply specify the clogged position of a transporting pipe in a short time by providing multiple branch pipes at a distance on the powder air stream transporting pipe, feeding the gas by pressure from the branch pipes to the transporting pipe at the fixed pressure and/or with the fixed flow, and checking changes of the pressure and/or flow. CONSTITUTION:When a clogged position is to be specified while a cutoff valve 7 is opened, switching valves 5a-5c are opened and closed in sequence from the upstream side. When the valve 5a is opened, for example, the other valves 5b and 5c are both closed. Gas does not flow to the downstream side of a powder air stream transporting pipe 2 from a branch pipe 3a, it passes the valve 7 and is discharged to the outside via a transporting tank side, thus the pressure in the pipe 3a is not increased, and the flow is not reduced. When only the valve 5b is opened, gas does not flow into the pipe 2 from the branch pipe 3b because a clog 4 exists in the pipe 2, the pressure in the pipe 3b is increased, and the flow is reduced. When only the valve 5c is opened, gas flows into the pipe 2, the gas pressure is not increased, and the flow is not reduced.
