Abstract

In una centrifuga a spinta, il caricamento con il materiale da centrifugare avviene mediante un tubo di riempimento che porta ad un fondo di spinta della centrifuga a spinta, il quale sbocca in un'apertura centrale di una girante di pompa, la quale distribuisce uniformemente il materiale da centrifugare e lo accelera alla velocità angolare dei panieri di centrifuga della centrifuga a spinta. Per impedire che particelle di sostanza solida delicate vengano distrutte nella introduzione nella girante di pompa, nel qual caso deve venire garantita contemporaneamente una portata di massa ottimale, viene proposto di munire gli spigoli anteriori delle palette di girante di pompa di arrotondamenti, i cui diametri corrispondono sostanzialmente allo spessore di profilo maggiore delle alette di girante di pompa.Contemporaneamente, le sezioni trasversali di flusso tra ogni volta due palette di girante di pompa nel campo di ingresso vengono crescentemente aumentate mediante il disco di guida altamente curvato verso la zona di centro, per cui, per una portata di massa ottimale, viene ottenuta una velocità di flusso ridotta che risparmia le particelle di sostanza solida nella zona di ingresso della girante di pompa.In a push centrifuge, the loading with the material to be centrifuged takes place through a filling tube which leads to a push bottom of the push centrifuge, which opens into a central opening of a pump impeller, which evenly distributes the material to be centrifuged and accelerates it to the angular speed of the centrifuge baskets of the push centrifuge. In order to prevent delicate solid particles from being destroyed in the introduction into the pump impeller, in which case an optimum mass flow rate must be guaranteed at the same time, it is proposed to equip the front edges of the pump impeller vanes with rounding, the diameters of which correspond substantially to the thickness of the larger profile of the pump impeller fins. At the same time, the transversal flow sections between each time two pump impeller vanes in the inlet field are increasingly increased by means of the highly curved guide disk towards the center area, to to which, for an optimal mass flow rate, a reduced flow rate is obtained which saves the particles of solid substance in the inlet area of the pump impeller.
