すように１２でいた。For example, in a device such as a fly ash processing device installed in a coal-fired boiler, the powder and granules collected in a hopper are transferred from the discharge port to the required location via a vacuum-type air-mediated transport pipe for processing. During the operation in which powder and granules are sucked into the pipe from the discharge port, a bridge of powder and granules is formed on the top of the hopper at the discharge port, causing the powder to fall (or disappear) into the transport pipe. Conventionally, this was broken down using manual processing such as a stick from the top of the hopper.

した制御手段を設けてもよい。The powder and granular material transport pipe system of the present invention is the same as a) in which an on-off valve 9 is provided on the upstream side of the "transport pipe" in the conventional transport pipe system. This opening/closing valve 9 can be opened and closed manually as necessary, and the vacuum pressure p in the transport pipe 1 located close to the hydro exhauster 2 fluctuates and decreases over a long period of time [~
Control means may be provided to automatically close the valve upon detection of a phenomenon occurring.

Create a vacuum in the transport pipe 1 1-7, let the air taken in from the air intake 1 flow into the transport pipe 5 3, and discharge the powder and granules 7 from each hopper 5 connected to the transport pipe 1 from 6. The conveying air drawn into the conveying pipe 1 passes through the hydro exhauster 2 and the air separator 8, and accumulates at a predetermined location. Silk is being pounded for a long time at 1F normal pressure (during this operation, powder and granular material 7 is poured into the soil part 1-16 of the hopper J'J).L
When a bridge is formed and grows to the point where it completely prevents the passage of the powder and granules, the vacuum pressure in the transport pipe (I) will rise to a certain level. The vacuum pressure p changes to -2f and maintains that value. The fact that this fluctuation in vacuum pressure lasts for a time that is no longer temporary does not mean that bridges due to powder and granular materials are not formed in at least some of the hoppers 5. The opening/closing valve 9 is manually closed by visual confirmation of a vacuum word or the like or by a warning from an alarm means. If an automatic control means is provided, the on-off valve 9 is automatically closed.

。-1- (When the valve 9 is closed, the conveying air from the air intake 4 is completely cut off, so the vacuum pressure in the conveying pipe is increased to a vacuum pressure close to the limit of hydro exhaust performance, In addition, the bridge that was not formed will be destroyed by the large pressure difference applied to T, and on the other hand, the gas existing between the particles in the bridge will expand t2 and promote the above-mentioned destruction. The bridge is destroyed and dissolved. Of course, the broken particles of the bridge are removed via the transport pipe. The destruction of the bridge is generally completed in a short period of time.
After a predetermined short time, the on-off valve 9 can be opened to return to normal operation. In addition, after the valve 9 is restarted, the vacuum pressure p in the transport pipe does not return to the normal value of 1F (a)', but indicates the previous slightly higher vacuum pressure [)I, which indicates that the bridge has not been resolved. The closing and opening operations of the on-off valve 9 may be repeated until the vacuum pressure reaches a normal value.
