  • Patent number: 8475351
    Abstract: The present invention provides a zonal centrifuge which has superior workability and functionality when a sample is filled and extracted. An oil bearing fitted to an outer circumference of a lower tube of a rotor is arranged on an internal face of a bearing housing fixed over a door adapter of the centrifuge. As the oil bearing and the lower tube are lubricated, a vacuum environment in a rotor rotating chamber is maintained. A rotating seal located at an upper leading end of the lower tube of the rotor and a fixing seal facing the rotating seal are arranged and provided in a sealed space formed by a mechanical seal member and the bearing housing, and the fixing seal is so manipulated as to be able to freely join and separate from the rotating seal.

    Abstract: This separator is a centrifugal device for separating solids from contaminated effluent such as oil or water base coolants and other liquids which are used in a variety of grinding and machining applications in the glass, ceramic and metal-forming industries. A containment liner or bladder lines the interior of the separator and communicates with fluid inlets and outlets. An inlet orifice allows for the pulling of a vacuum which holds the bladder in place on the interior walls of the separator. Periodically, rotation is stopped, vacuum is released and the bladder is allowed to invert and drop below the separator. Hanging in this inverted position, it is easy to clean or remove the solids from the inverted bladder.

    Abstract: To separate minerals, they are mde up into a slurry applied through feed pipe 46 to a vertical-axis spiralinder 32 spinning on its axis to generate 10 g centrifugal force. The spiralinder is also subjected to axial vibration at 5 to 10 Hz. A film of slurry is held centrifugally to the internal surface of the spiralinder and kept in suspension by the vibration. The denser (i.e. higher specific gravity) particles in the slurry tend to be most firmly pinned centrifugally. The lightest particles thus drop first into the trough 44 and are dumped by switchable box 45. The centrifugal spinning is then slowed and the dense particles scoured off by wash water. The whole cycle is then repeated.

The cylinder 301 is also subjected to axial vibration at 5 to 10 Hz. The cylinder widens at a half-angle of 1.degree., and its axis is inclined at 2.degree. upwardly in the direction of widening. A film of slurry is held centrifugally to the internal surface of the cylinder and kept in suspension by the vibration. The denser (i.e. higher specific gravity) particles in the slurry tend to move preferentially radially outwardly (centrifugally) and to move downwardly in the boundary layer (under Earth's gravity). The action of the washing water B is to displace waste accidentally entrained with the higher-specific-gravity-particles. The valuable higher-specific-gravity particles overflow downwardly continuously at C and are collected.

    Abstract: A centrifuge comprises a rotor which tapers conically downwardly from a maximum diameter upper region to a central bottom opening through which a liquid entry pipe projects upwardly. An outlet end of the entry pipe is shrouded by a concentric cone which is mounted for rotation with the rotor. A flexible diaphragm is secured to the outlet end of the pipe and extends towards the cone so that liquid entering the rotor is directed to flow over an inwardly facing surface of the cone. By this means, the spin of the rotor is transmitted immediately to the liquid. During operation of the centrifuge, rapid changes in the rate of rotation of the rotor are effected so that solids which have separated from liquids in the rotor and have accumulated in the upper region are dislodged therefrom.
