Abstract
An apparatus for scum removal is disclosed wherein toothed paddle induces turbulent effect on the fluids present in the reactor by means of its rotary motion. This results in both breaking and radial displacement of the scum, accumulated on the fluid during the course of the biochemical or chemical reaction, towards the outlet of the reactor, thereby ensuring that the reaction continues in scum free environment uninterruptedly.
Claims5
An apparatus for scum removal for industrial application, the apparatus comprising a plurality of toothed paddle arms (4) supported on a shaft (2) and connected to the shaft (2), the shaft being provided with a bearing (3), the shaft being connected to a reversible prime mover (5), the toothed paddle arms, shaft and bearing being incorporated in a mixture of liquid and solid reactants (7) contained inside a reactor (1), the reversible prime mover (5) driving a drive from a source and transmitted through the shaft-bearing arrangement, rotary motion being transmitted horizontally to the paddle or vertically through a transmission mechanism (6), to the paddle, thereby displacing the scum radially to the outlet of the reactor.
