Device for aerating and sprinkling laden liquids.

摘要

Apparatus for aeration and aspersion of a liquid comprises a hollow tube (1) containing a turbine (4) which rotates around a central axis (4a) and which is driven by a motor (3). Transverse holes (2) penetrate the lower end of the tube, allowing liquid to pass through in either direction when loaded with matter in suspension. The flow direction depends on the direction of motor rotation. The turbine imparts a helical trajectory to the liquid, whether rising or falling, to assure dispersion at the point of arrival of the flow. Also claimed is an apparatus for aeration and aspersion of a liquid, used to recover the contents of a head (10) in a vinification vessel (8), in which the length of (1) is slightly longer than the depth of (10). The holes are situated at the lower end of (1) and are used to pass the liquid in one direction or another, the tube containing in its interior a turbine (4) with a means to rotate about (4a). The turbine rotates at the same speed as (4a) and (3) is either electrically or pneumatically powered, being coaxial to (1). The motor interlocks with the lower part of (1) with respect to its casing. The turbine comprises a helical spiral (4b) made from one or more turnings to give (4a), and further comprising a collar in the form of a corresponding exterior spiral, the assembly being designed to slip into the interior of (1).
