Abstract
A method of installing a sleeve within an vortex finder of a cyclone separator to adjust the diameter of the vortex setting. To facilitate installation of the sleeve, the dish-shaped bottom of the cyclone is mounted on a plate which can be lowered and then pivoted aside. The sleeve is provided with a collar which is stitch welded to the vortex finder to retain the sleeve in place. Alternatively, the collar and vortex finder are provided with a bayonet joint to releasably retain the sleeve. A kit of sleeve assemblies of different diameters is provided to accommodate the adjustment of the vortex setting.
Claims1
A method of installing a quick-change sleeve in a vortex finder of a cyclone having a bottom dish and orifice in order to change the diameter of the vortex finder, which vortex finder constitutes the sole outflow for the light fractions separated in a centrifugal cyclone, a jigging cyclone or a clarifying cyclone, said method comprising the steps of:
- (a) providing a plurality of doughnut shaped metal holders having a flange thereon which abuts against the lower edge of said vortex finder,
- (b) providing a sleeve kit containing a plurality of sleeves, each one thereof having a length of at least 0.3B, where B is the inner diameter of the cyclone bowl, and a different graduated diameter from any other sleeve in said kit, to adjust the outflow of light fractions,
- (c) welding a sleeve of said sleeve kit inside of a corresponding said doughnut shaped holder,
- (d) cutting a bayonet slot at the lower edge of said vortex finder sleeve,
- (e) welding a bayonet pin to the flange above said doughnut shaped holder to fit into said bayonet slot, and
- (f) selectively limiting the diameter of said sleeve in said kit from 0.3B to 0.5B where B is the inner diameter of the bowl of said cyclone.
