Title: Multiple unit filter with backflush - using rotary multiple port valves for inlet and outlet flow diversion
Inventor: MILLER PETER ANTHONY
IPC: B01D35/12
Filed: 1975-07-01
Abstract: A filter unit consists of a number of individual chambers each of which has an inlet and an outlet connection. All the inlets are connected to a common multi-port valve and all the outlets to a similar one. The valve ports are arranged so that one chamber can be back-flushed for cleaning whilst the others are on line for filtration. The unit is used in multi-chamber filters used for the clarification of wash water, cooling water, cooling fluids etc. in systems where one or more chambers are taken off line in rotation for cleaning by back-flushing. By using multi-port rotary valves and arranging the filter chambers on the circumference of a circle a simple and compact construction is possible, as compared with linear arrangements which have two individual valves per chamber.
