DEVICE FOR FLUSHING PIPE INNER SURFACE IN PROCESS FLOW Russian patent published in 2013 - IPC B08B9/32 

FIELD: process engineering.

SUBSTANCE: invention relates to cleaning pipe inner surface of scale and sludge and different-length pipe (6 to 14 m) inner surface degreasing. Proposed device comprises feed roll-table and conveyor for transverse feed of pipes, flushing fluid and air feed nozzles arranged at separate posts and positions, and flushing fluid forcing system composed of a set of pumps. Besides this device is equipped with three lifters with prisms arranged subject to pipe lengths in the area of said conveyor. Two prisms are arranged in the area of shorter pipes while third prism stays in that of different-length pipes. Every prism is arranged at carriage displacing in vertical guides from the drive. Prism located in the area of different-length pipes is composed of portal and equipped with tray and container for sludge collection. Tray length equals the difference between pipe maximum and minimum lengths. Prism lifting drive is arranged outside of flushing fluid collection area and composed of power cylinder coupled by two-arm lever with aforesaid carriage. Two prisms participate permanently in flushing of all pipes. Prism arranged in the area of different-length pipes is used for flushing long pipes, for example, longer than 9 m, for ruling out pipe overturning.

EFFECT: higher efficiency.
