Transportable aspiration liquid device for removing aqueous phase contained in tank of compound vacuum truck, has chamber ensuring aspiration of liquid through opening and joint evacuation through outlet with pressurized water

摘要

#CMT# #/CMT# The device (1) has an inlet (2) intended to be connected to a flexible device (3) supplied with high pressurized water. An outlet (4) is intended to be connected to a liquids evacuation flexible device (5). An opening (6) is equipped with a filtration grid. A venturi system (7) allows usage of pressurized water supplied to the inlet to create depression in a depression chamber (9) internal to the device. The chamber ensures aspiration of liquid through the opening and joint evacuation through the outlet with pressurized water supplied to the inlet. #CMT# : #/CMT# An independent claim is also included for a vehicle. #CMT#USE : #/CMT# Transportable aspiration liquid device for removing an aqueous phase contained in a tank of a vehicle i.e. compound vacuum truck (all claimed). #CMT#ADVANTAGE : #/CMT# The chamber ensures aspiration of liquid through the opening and joint evacuation through the outlet with pressurized water supplied to the inlet, thus enabling a suction hose to withdraw the light phase of the tank and heavy fraction phase of the tank, and hence emptying the contents of the tanks while avoiding or strongly decreasing quantity of water aspired in the tank of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial longitudinal sectional view of a transportable aspiration liquid device. 1 : Transportable aspiration liquid device 2 : Inlet 3 : Flexible device 4 : Outlet 5 : Liquids evacuation flexible device 6 : Opening 7 : Venturi system 9 : Depression chamber.
