Abstract

An apparatus for mixing a gaseous medium and/or a liquid medium with a fluid, such as a liquid or a liquid suspension, said apparatus including a stirrer that is intended to be rotated about a substantially vertical axis in a container that it contains said fluid, and has a substantially horizontal and circular underside with paddles fixed to it, whose paddles when rotating the agitator cause the fluid to circulate upwards, and afterwards outwards along said underside, while rotates in the direction of rotation of the agitator, and organs for supplying said means to the underside of the agitator, in which the supply means include at least one nozzle directed substantially at right angles to the geometric axis of rotation of the agitator, located under the stirrer, consisting of an elastomeric material and having a slot-shaped nozzle outlet, the outlet of which can be closed automatically when the supply of said medium is interrupted due to the inherent elasticity of the nozzle material, the mouth of the nozzle being arranged a considerable distance inward from the periphery of the agitator, such that at the selected rotation speed of the agitator and with the selected paddle design, substantially all of the medium supplied through said outlet in a previously dispersed state in said upward flow, passes into the region of the stirrer blades and is then dispersed by the shear action of the blades, spreading the blades along at least 50% of the distance between the center and the periphery of the stirrer.
