The invention relates to those hydrocyclones which, for instance due to their length, do not lend themselves to manufacture in a single piece but are divided up into sections, which until now have been connected to one another usually with the help of flanged joints. In accordance with the invention it is proposed that the sections (52, 58, 60, 62) of a cyclone (50) be executed in such a way that the end of a section (e.g. 58) fits internally into the following section (60) in the direction of the flow and projects for a small distance into it, with the joint being sealed, if necessary, by a gasket. The sections are held securely together by means of a previously disclosed eccentric lock (70) of the folding strap type, at least two of which are arranged at each joint. Cyclones constructed in accordance with the invention can be imparted with curved form in order to facilitate, for example, their arrangement in batteries, and in those cases in which permanently connected cyclones are preferred, the sections can be welded together without the risk of crack formation, thanks to the fact that the arrangement in accordance with the invention produces fillet joints between the sections. |
