DOUBLE-ACTION PUSHER CENTRIFUGE AND PUSHER BASE DEVICE
First Claim
1. A double-action pusher centrifuge for separating a mixture into a solid cake and a liquid, the double-action pusher centrifuge comprising:
- a screen drum including a front region and a rear region, and being rotatable about an axis of rotation;
a pusher base device including an outer ring region, being disposed in the screen drum, and being movable to and fro along the axis of rotation so as to alternately displace the solid cake in the screen drum by the outer ring region in an operating state;
a plurality of axial passage openings disposed in the outer ring region of the pusher base device, and connecting the front region and the rear region of the screen drum;
an inflow disk;
a feed unit arranged at the inflow disk, and the feed unit and the inflow disk being configured to introduce the mixture via into an empty space arising on the screen drum on displacement of the solid cake; and
an inflow gap which is not interrupted in a peripheral direction, being configured to apply the mixture into the empty space on the screen drum, and being disposed between an inflow edge of the inflow disk and a pusher base plate of the pusher base device with an inflow region.

Abstract
A double-action pusher centrifuge separates a mixture into solid cake and liquid. The pusher centrifuge includes a screen drum rotatable about an axis and in which a pusher base device is arranged to be movable along the axis of rotation. The solid cake is displaced by an outer ring region of the pusher base device. A plurality of axial passage openings are disposed in the outer ring region and connect front and rear regions of the screen drum. A feed unit is arranged at an inflow disk such that the mixture can be introduced via the feed unit and the inflow disk into empty space on the screen drum on displacement of the solid cake. An inflow gap applies the mixture into the empty space, and is between an inflow edge of the inflow disk and a pusher base plate of the pusher base device with an inflow region.
