Title: Industrial filtration apparatus and method for the separation of solids from a fluid stream
Inventor: CLOUGH GEORGE FRANCIS GILBERT
IPC: B01D33/01
Filed: 1991-08-22
Abstract: Industrial filtration apparatus for the separation of solids entrained in a fluid stream comprises: a flexible perforate filtering sleeve closed at one end such that fluid can pass through perforations in the sleeve but entrained solids of a predetermined size are retained within the closed end of the sleeve. The apparatus has a structure for holding the sleeve about a discharge pipe for the fluid at a point between the closed and open ends of the sleeve, and for restraining movement of the sleeve away from the pipe; the apparatus is adapted such that in response to a predetermined fluid (e.g. hydraulic) pressure within the sleeve between its closed end and the discharge pipe, the closed end is allowed to be displaced away from the discharge pipe, thereby drawing a portion of the sleeve nearer its open end into a position forward of the pipe to expose said portion to the fluid stream.
