Self-cleaning filter and vortexer
First Claim
1. A combination self-cleaning fluid filter and vortexer means for separating particulates from an entraining fluid comprising:
- a substantially cylindrical cannister having a tangentially directed inlet port communicating with the interior thereof and a particulate collecting port spaced from said inlet;
a clean fluid outlet port disposed substantially coaxially with the longitudinal axis of said cannister;
filter means mounted over said outlet port within said cannister;
said filter means being mounted over said outlet port for rotation in the same direction as the flow of entraining fluid and particulates entering said cannister from said inlet to preclude caking of said filter means with said particulate material by dynamic self-cleaning action;
arcuate baffle means intermediate said filter means and said tangentially directed inlet port in said cylindrical cannister enhancing vortex flow in the fluid and for shielding said filter means from direct impingement of fluid material from said inlet port;
said baffle means dividing the flow of fluid material in said vortexer to mix cleaner fluid with fluid material from said inlet port on one side thereof and to direct the flow of cleaner fluid about said filter means on the other side thereof; and
said filter means comprises a self-rotatable filter rotatable by means of the tangentially directed inlet fluid, said filter means including a plurality of outwardly projecting finger members formed by Corolis curves.

Abstract
A self-cleaning filter and vortexer is provided in which a filter rotates over the clean fluid outlet port of a vortexer cannister in the direction of the flow of fluid into the tangential inlet port of the vortexer. The peripheral velocity of a freely rotating filter will approximate the flow velocity of the fluid into the tangential inlet port to enhance the centrifugal acceleration effect of the vortexer and the dynamic cleaning of the filter medium. This acceleration enhances centrifugal separation of the heavier particulates in the vortexer and enhances the dynamic cleaning of the fines and other particulates from the filter medium. The drive mechanism for rotating the filter may be designed to be uneven so as to shake the filter medium as it rotates. The flow of fluid will pass thru the filter medium and be exhausted as a cleaned fluid into the outlet port of the vortexer cannister. Throughout this disclosure centrifugal refers only to the normal acceleration associated with curvilinear motion while dynamic refers to all three components of relative curvilinear motion, namely, normal, Corolis and tangential. The vortexer (cyclone) herein referenced to utilizes the centrifugal component only while the rotating filter elements herein referred to are so designed as to utilize all three of the relative curvilinear components, hence the distinction throughout between centrifugal and dynamic effects.
