Claims7
A filter apparatus capable of vibrating accumulated filter cake for improved solid-liquid filtration of a suspension, said apparatus comprising:
- a housing for containing a suspension to be filtered;
- a filter mounted in said housing and accumulating a filter cake as a filtrate passes through a filter surface of said filter;
- a vibratory apparatus unconnected to said housing, including:
- a vibratory body positioned to contact or protrude into the filter cake so that only a portion of the filter cake thickness vibrates;
- a pressure rib connected to said vibratory body;
- a connecting part;
- and
- a vibratory drive operatively connected to the vibratory body by said connecting part to cause said vibratory body to vibrate.
