Projectile dispensing system and use

摘要

In one embodiment the present invention is a system comprising a feeder to feed projectiles. There is a conveyor for metering the projectiles, and that conveyor is in communication with the feeder. A pipe is in communication with the conveyor, for impelling projectiles through the pipe. In another it is use of a barrel internally lined with a helical blade for unconfined metering of projectiles to clean a gas pressurized pipe.

主权项

1. A projectile dispensing system for cleaning in situ encrusted pipe comprising:
a) a feeder to feed hard abrasive projectiles; b) a rotatable barrel internally lined with a helical blade, to meter projectiles received from the feeder, the barrel communicating with and positioned external to the feeder; and c) a pipe communicating with and positioned external to the barrel, to receive from the barrel, projectiles for impelling through the pipe by gas flow, for simultaneous full length cleaning and encrustation ejection out said pipe.
