Abstract
Described is a self-cleaning filter for a liquid stream confined in a pipe 20. The filter includes a porous ceramic filter body 30 having a power source 35 attached thereto. Upstream from the filter body a helical rib 50 and a sump drain tube 42 are provided. In operation, as the filter becomes clogged, an electrical current is applied causing the ceramic body to exhibit ultrasonic transducer properties which dislodge particulates from its upstream face 31. At the same time, a sump valve 41 is opened to remove the particulate-rich liquid. The helical rib imparts a rotary motion which creates a rotary flow component across the upstream face of the filter.
