RAILWAY CAR BATHROOM WASTES ACCUMULATION TANK Russian patent published in 2011 - IPC B61D35/00 

FIELD: transport.

SUBSTANCE: invention relates to sanitary equipment and may be used in railway cars. Proposed accumulation tank comprises five-start-prism-shaped housing 1 with superstructure 2 incorporating gas filter. Top wall of superstructure 2 supports branch pipe 4 communicating tank inner space with vacuum system to receive bathroom wastes. Said branch pipe is communicated with gas filter. Tank housing 1 incorporates integrated fluid and electrical heating system. Two suck-off pipes 11 are fitted inside the tank, each extending therefrom and stopped by plugs 13 that serve for coupling with intake elements of surface stationary waste receivers. Air flow pipes 13 are laid parallel to each suck-off pipe 11. In operation, bathroom wastes come into tank space forced by vacuum generated therein. Tank thermal state pickups is controller by temperature transducer. In winder, bathroom wastes accumulated inside tank 1 are heated by heat carrier fed therein.

EFFECT: higher reliability at low temperatures, reduced overall dimensions.
