PCT No. PCT/SE84/00066 Sec. 371 Date Oct. 12, 1984 Sec. 102(e) Date Oct. 12, 1984 PCT Filed Feb. 24, 1984 PCT Pub. No. WO84/03236 PCT Pub. Date Aug. 30, 1984.According to the invention a plurality of hydrocyclones (10) for cleaning liquid suspensions are combined to form uniform packages (80), each of which comprises, for example, ten hydrocyclones. The central part of each cyclone package is made up of a double chamber, one part of which is intended for the supply of the inject, i.e. the phase of the suspension which is to be cleaned, while the other part is intended for the removal of the cleaned phase, or accept. The double chamber preferably consists of a pair of twin conduits (65, 70), that is to say, two collecting conduits disposed tightly adjacent and parallel with each other, for receiving and delivering the respective suspension phases from the cyclones. The cyclones (10) are designed to be connected to the twin conduits via leak-tight pipe connections of the sleeve type, such as those known as chevron couplings (50), for example. This means that each separate cyclone (10) can be pushed plug-fashion into its position in the package (80) and at the same time can be connected leak-tightly to the twin conduits (65, 70). To do this, the cyclones are manipulated by their reject end, i.e. the end where the suspension phase in which impurities are entrained emerges, preferably through a transparent glass unit (40) so that the appearance of the stream of reject in the package can be observed. A plurality of such cyclone packages (80) may be assembled together in various configurations to form larger hydrocyclone batteries.
