Process and apparatus for pumping a thick viscous mass

摘要

method and apparatus for pumping a viscous mass thick, living in the open air, after having made siffisamment fluid or liquid to be pumped.;the device according to the invention, consists in a known manner by itself by a barge or float or sled adapted to slide on the surface of the thick viscous mass.is remarkable because it contains, on the one hand, suspended below the support frame (2) of the pump.a wire mesh cage (5) or entering the mass (m) to define a shallow surface layer of the body, and, on the other hand.a bed (7) of resistors positioned a short distance from the bottom of the cage.in such a way as to be located in this layer in order to heat up enough that it thins out and allow the pumping.
