Problems solved by technology

[0006] Another problem associated with vortex finders is that during operation of the cyclonic separation device, the precession of the vortex core around the interior of the vortex finder causes a considerable noise
The use of a center body located entirely within the vortex finder is recognized as helpful in reducing the noise associated with the exhaust fluid to some extent, but no attempt has been made to further reduce noise with a center body

Embodiment Construction

[0020] Embodiments of the Invention

[0021] figure 1 Cyclone separation apparatus 10 is shown suitable for use in a cyclone vacuum cleaner. In fact, in this example, the cyclone separation device consists of two concentric cyclones 12, 14 for sequentially removing an air stream. Other features of the vacuum cleaner (eg head or hose, motor, motor filter, handle, support wheels, etc.) are not shown in the drawings as they do not form part of the invention and will not be described further here. Indeed, in this embodiment it is the innermost high efficiency cyclone 14 that cooperates with a vortex finder, so it is the innermost cyclone 14 that is of interest to the present invention. It should be understood, however, that the present invention can be applied not only to cyclone apparatuses suitable for use on vacuum cleaners, but also to cyclone apparatuses having only a single cyclone.

[0022] The innermost cyclone 14 includes a cyclone body 16 which is generally frustoconi...

Abstract

The invention provides cyclonic separation apparatus containing a cyclone body having at least one fluid inlet and a fluid outlet, the fluid outlet being concentric with the longitudinal axis of the cyclone body. The cyclonic separation apparatus also contains a vortex finder projecting from an end surface of the cyclone body into the interior of the cyclonic separator, and a centerbody located partially within the vortex finder. The centerbody projects beyond the distal edge of the vortex finder so that the distance between the end surface of the cyclone body and the further end of the centerbody is at least twice the smallest diameter of the vortex finder, and the cross-sectional area of the centerbody is circular at any point along its length.

Description

technical field [0001] The present invention relates to cyclone separation devices, in particular, but not exclusively, to cyclone separation devices for vacuum cleaners. Background technique [0002] Cyclone separation plants consist essentially of a frustoconical cyclone body with a tangential inlet at its larger, usually upper end, and a conical opening at its smaller, usually lower end. An internally entrained particle fluid enters through the tangential inlet and follows a helical path around the cyclone body. During this movement the particles are separated from the fluid and are carried or dropped through the conical opening into a collector from which they can be suitably disposed of. The cleaned fluid, usually air, travels towards the central axis of the cyclone body to form a vortex and exits the cyclone through a vortex finder located at the smaller (upper) end of the cyclone body and in its center Axes are aligned. [0003] The vortex finder usually takes the ...
