Centrifuge bowl with improved abrasion resistance - having grid formed from wedge-shaped bars with transverse and vertical mounting in conical bowl

Centrifuge bowl for a sieve type centrifuge has a conical shape. It is constructed from segments each of which is in the form of a grid formed from a series of rods with wedge or trapezium shaped cross section. The narrow aperture between adjoining rods is mounted on the inner surface of the bowl an...

description Centrifuge bowl for a sieve type centrifuge has a conical shape. It is constructed from segments each of which is in the form of a grid formed from a series of rods with wedge or trapezium shaped cross section. The narrow aperture between adjoining rods is mounted on the inner surface of the bowl and this serves to support the filtered material. The edges of the segments on both sides have reinforcement ribs mounted along the conical profile at the stress points of the segments. These ribs consist of a protective plate which in the longitudinal direction extends over the complete impact length of the segment on the inside of the bowl and which overlap the adjoining segments. Used in sepg. materials esp. abrasive ones such as coal and sand. The construction of the connection joints of the centrifuge ensures that premature failure of the weld connections and reinforcement ribs does not occur. L'invention concerne les constructions mécaniques. Le bol de centrifugeuse faisant l'objet de l'invention est du type se présentant sous la forme générale d'un cône tronqué et constitue par des secteurs 1 se presentant chacun sous la forme d'une grille filtrante composée de barreaux parallèles à section transversale trapézoïdale, et est caractérisé en ce que ses nervures de rigidité comportent chacune une partie de blindage relativement large 7, disposée suivant toute la longueur du joint des secteurs 1, à l'intérieur du bol, et recouvrant les extrémités jointées de la grille. La centrifugeuse en question est destinée à séparer la phase liquide et la phase solide d'un système liquide hétérogène, notamment d'un matériau tel que le charbon ou le sable traité dans l'eau dans une laverie de l'industrie houillère, chimique, des matériaux de construction et d'autres branches de l'industrie.
