Problems solved by technology

Another consideration is that the bowl has a potential tendency for axial displacement, such as in the case of unbalance or movement of axial fluctuations in the liquid in the bowl, which will lead to unstable operation

Embodiment Construction

[0030] figure 1 Shows a vertical section of an automated tube bowl centrifuge separator with the middle section removed so that a horizontal section can also be shown. The centrifuge separator comprises a cylindrical separator bowl 10 mounted in the middle 11 of a separator housing 13 . The separator drum 10 is preferably a cylindrical drum having a relatively small diameter D and length L with a ratio L / D of about 5 / 1 or greater. Inside the separator drum 10 is mounted a piston mechanism consisting of a piston head 12 connected to a piston shaft 14 .

[0031] A variable speed drive motor 16 is connected to a drive pulley of a spherically mounted bearing and spindle mechanism 18 . This connection is formed by a drive belt 20 on an annular extension 21 of the shaft at the upper end of the separator housing 13 . The drive motor 16 is controllably operated to rotate the separator bowl 10 at the speed required to separate the feed liquid. A piston shaft clutch 22 is mounted on...

Abstract

A centrifugal separator provides for discharge of solids by either an axial-motion scraper or a piston / extrusion assembly. The axial-motion scraper (80) is used with hard-packed or friable solids, and includes an integral feed liquid accelerator and feed holes. The piston / extrusion assembly is used with pasty solids, and includes a piston (12) extending into a separator bowl (10) and having openings (45) permitting fluid communication across the piston. After separation is complete, a centrate valve (34) closes one end of the bowl, and the piston is moved axially in the bowl by an actuator. A bowl suspension employs a spherical mounting structure (96) and a short, spindle (98). A bearing (100) and the spindle (102) of bowl are mounted within the bearing housing. The suspension is retained by a ring and retaining member secured to the separator in compressive contact with the spherical portion of the bearing housing.

Description

[0001] This application is a divisional application of an invention patent application with the application number 03808279.9, the application date being April 14, 2003, and the invention title being "a centrifuge for discharging solids with a scraper or a piston". technical field [0002] The present invention relates generally to a centrifuge, and more particularly to a centrifuge capable of automatically discharging solids accumulated during separation. Background technique [0003] Many types of centrifugal separators are known for separating heterogeneous mixtures into components according to specific gravity. A heterogeneous mixture, which can be referred to as feed material or liquid, is injected into the bowl of the separator. The drum rotates at high speed and pressurizes the mixture particles, which have a high specific gravity, to separate them from the liquid by sedimentation. Thus, a dense cake of solids is pressed tightly against the surface of the bowl, while...
