Abstract
1341138 Measuring density INDUSTRIAL FILTER & PUMP MFG CO 22 Oct 1971 [18 Jan 1971] 49247/71 Heading G1S [Also in Division B1] The cake discharge outlet of a filter apparatus 10 for separating solids and liquids is controlled by means of a density detector 35 which opens outlet valve 31 to remove solids-rich liquid when the density in the chamber 12 below the filter elements 16 exceeds a predetermined value. The detector operating to close valve 31 again when the liquid density falls back below the predetermined value. In operation of the filter apparatus liquid to be filtered enters at 18 passes through the filter elements 16 and filtered liquid exits at 20. Solid cake builds up on the outside of the filter elements and is periodically discharged ‘simultaneously from all the elements whereupon it falls into the chamber 12 below the filter elements and is withdrawn by port 28 and valve 31 as the density therein exceeds the predetermined value. The density responsive means is arranged so that it will not operate to open discharge valve whilst the cake is being discharged from the filter elements.
