Problems solved by technology

Especially in the case of sensitive substances, this can lead especially to particle fragmentation, i.e., for example, solid particles distributed in the suspension supplied to the centrifuge break up into smaller pieces in an uncontrolled manner upon sudden acceleration of the process, For example, if the particle size of the particles plays a role in the final product, this can have a negative impact on the quality of the resulting solid cake

Embodiment Construction

[0046] Figures 1a to 1d An example of a double-acting pusher centrifuge known from the prior art is shown, which was already discussed in detail at the beginning and which therefore need not be discussed any longer at this point.

[0047] figure 2 The main components of a first embodiment of a double-acting pusher centrifuge according to the invention are shown in a highly schematic representation in section by way of example. In this regard, at least for particular embodiments, the double-acting pusher centrifuge of the present invention may be considered to be based on Figure 1a-Figure 1d Another development of the known double-acting pusher centrifuge, where the main difference can be seen in the inflow gap, which is not interrupted in the peripheral direction, and this is not present in the known double-acting pusher centrifuge .

[0048] Basis identified generally with reference numeral 1 figure 2 The inventive double-acting pusher centrifuge serves to separate th...

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. The present invention also relates to a pusher base device for the double-action pusher centrifuge.

Description

technical field [0001] The invention relates to a double-action pusher centrifuge and a pusher base arrangement for a double-action pusher centrifuge according to the preambles of independent claims 1 and 12 . Background technique [0002] Centrifuges in most varied embodiments are common and are used in most varied fields of dehumidification of moist substances or mixtures of moist substances. Thus, discontinuously operated centrifuges, such as scraper centrifuges, are for example preferred for drying very pure pharmaceutical products, while continuously operated pusher centrifuges are particularly advantageous when large volumes of solid-liquid mixtures are to be separated continuously ground use. In this respect, depending on requirements, single-stage or multi-stage pusher centrifuges as well as so-called double-acting pusher centrifuges can be used. [0003] In pusher centrifuges of different designation class types, a solid-liquid mixture (for example, a suspension o...
