Abstract: 1529948 Hydrocyclones E L RASTATTER 29 Oct 1975 [1 Nov 1974] 44756/75 Heading B2P A number of hydrocyclones for classifying solids or separating solids from liquid are arranged in a cluster with their axes parallel, Fig. 2, and cylindrical portions 18 of the hydrocyclones form rigid connections between parallel walls 26 which together with a surrounding housing 34 define a liquid supply chamber 64 for feeding liquid through tangential inlets 62 in the portions 18 of the hydrocyclones. The walls 26 are formed by flanges moulded as integral parts of the hydrocyclone bodies which are of thermoplastics material e.g. nylon, and the flanges are interconnected by key members 31. In another embodiment, Fig. 7 (not shown), the walls are formed by flat plates which are rigidly connected by independently removable thermoplastics hydrocyclone bodies having integral threads mating with threaded openings in the plates. Each of the hydrocyclones includes a replaceable apex connection 68 which is made of ceramic and has an externally threaded portion projecting into an apex discharge chamber 82 defined between an inner wall 76 and a transparent outer wall 84 of a housing 80. Each apex connection 68 is secured to the inner wall by a nut 88, and the transparent outer wall is provided with an axially aligned opening and valve 98 for each hydrocyclone for introducing a back flushing fluid or for connection to a vacuum source. The apex cone sections may alternatively be connected to the discharge housing 80', Fig. 5, by threaded sleeves 105 which also form spacers between the walls 76 and 112 of the housing and to which are cemented corresponding transparent plastics rings 118. A ceramic probe 122 is adjustable axially within each ring and has a conical inner end surface 124 which cooperates with the apex end of the corresponding hydrocyclone to define an adjustable annular discharge orifice 125. The opposite ends of the hydrocyclones have moulded thermoplastics closure members 56 with vortex finders 58 which project into an overflow chamber 52 defined by a removable cover member 50. In another embodiment, Fig. 6 (not shown), the vortex finders project into a tank connected to a vacuum source for deaerating liquid which is received in the tank.
