The portion of aggregate (1) producing the stream is fixed onto one or several revolving joints (9,10), which are connected to a carrier element (8) that moves up- and down on the guide device (6) . Adjustment of the aggregate (1) producing the stream is carried out using a motor (12) and/or using the moment produced from the aggregate (1). Aggregate can be lowered into a vessel containing liquid using a lifting device on a guide and removed from it using a lifting device on a guide; during operation a stream of liquid is produced within the container direction of which can be changed using mechanical adjustment. |
