SEDIMENT WASHOUT DEVICE Russian patent published in 2008 - IPC G21F9/34 

FIELD: nuclear engineering; treatment of radioactively contaminated materials.

SUBSTANCE: proposed sediment washout device has electric drive, shaft, working liquid inlet pipe, housing, working chamber, and washing head with nozzle. Washing head with nozzle has facility for implantation into sediment and its crushing; it is also provided with pipe union disposed within working chamber and mounted therein coaxially with electric drive shaft. Facility for implementation into sediment and its crushing is essentially pipe-union mounted flange that carries cutting ribs controlled by electric drive disposed on movable platform which has guide posts. Electric drive shaft and washing head pipe union are joined together by means of ribs and mounted within working chamber through packing assemblies. Device is provided with control system that has personal computer, microcontroller, communication modems, and software. Proposed device can steadily operate in vessels as deep as up to 30 m.

EFFECT: enhanced coefficient of sparingly soluble pulp sediment extraction, reduced vibration and amount of working liquid and liquid radioactive waste.
