Liquid sucker for solids e.g. mud, has container with mechanical control that alternately switches on and off motors so that liquid flows out from one absorption chamber to other chamber when liquid in latter chamber gets drained

摘要

The sucker has a container with two absorption chambers (1, 2) and a mechanical control. Suction motors are assigned to each absorption chamber. The mechanical control switches on and off the motors alternatively, so that the liquid flows out from the chamber (1) to the other chamber (2) when the liquid in the chamber (2) gets drained. The chambers are sealable opposite to suction side of the motors using main valves.
