Title: Improvements in and relating to apparatus for the de-aeration of viscous liquids
Inventor: NEWELL ROBERT ARTHUR
IPC: B01D19/00
Filed: 1955-03-07
Abstract: An apparatus for the continuous deaeration of viscous liquids comprises two or more conical plates in parallel arranged one below the other in a container having an outlet at the bottom and connected to a vacuum pump, the plates being spaced from the wall of the container with the rim of each succeeding plate at the same distance as or spaced further from the wall of the container than, the rim of the plate above it, and a number of concentric pipes for feeding the viscous liquid directly to the top of each plate. As showns, the apparatus comprises a cylindrical container 1 which can be maintained under vacuum by a vacuum pump (not shown) coupled to conduit 2.  The container has a roof portion 3 attached to the container 1 by bolts <PICT:0787348/III/1> <PICT:0787348/III/2> (not shown) passing through flanges 4, 5.  Suspended from the curved portion of the roof by struts 6, 7, 8 are pipes 9, 10, 11, 12 which are held in concentric relationship by spacer pieces (not shown) at suitable points along their length.  Frustoconical plates 13, 14, 15, 16 are attached to the pipes by screw threads, plates 13 and 14 being attached to pipe 9, plate 15 to pipe 10 and plate 16 to pipe 11.  Each plate has above it a cylindrical wall 17 forming a vessel 19, each wall 17 having arcuate holes 18 extending substantially around the whole of the periphery of the wall at its base.  Pipes 9, 10, 11, 12 are connected by pipes 22, 23, 24, 25 respectively to a ring main 26 fixed by struts 27 to the outside of the roof portion 3 of the container.  As shown, pipe 22 is a continuation of pipe 9.  The ring main has a feed pipe 28 connected to a source of supply of viscous liquid (not shown).ALSO:An apparatus for the continuous deaeration of viscose comprises two or more conical plates in parallel arranged one below the other in a container having an outlet at the bottom and connected to a vacuum pump, the plates being <FORM:0787348/IV (a)/1> spaced from the wall of the container with the rim of each succeeding plate at the same distance as, or spaced further from, the wall of the container than, the rim of the plate above it, and a number of concentric pipes for feeding the viscose directly to the top of each plate.
