<p>A method and a device of sucking and conveying various types of liquids and, without adding any air of any other gas or gas mixture to the liquid, to collect the liquid in a closed container or receiver (32), or to directly transfer the liquid to another liquide system whereby a liquid/air/gas mixture is sucked by means of a suction nozzle (2), and is brought to pass a separation and defoaming filter (3) to a de-air receiver (4) in which the liquid is allowed to slowly flow along the walls of the receiver or along an inclined plane (25) and to be collected at the bottom of the receiver (4), whereas the air which has followed the liquid into the system, and which, in the form of air bubbles may have been included in the liquid, is allowed to leave the liquid at the upper part of the receiver (2), whereafter the liquid, after a predetermined volume of liquid has been collected at the bottom of the receiver (4) is drained through a valve (27, 28) at the bottom of the receiver, preferably by automatic opening and closing of said valve.</p> |
