Abstract
A centrifugal liquid purifier comprising a vertically extending hollow axle secured on a base and having an inlet and an outlet for liquid, both the inlet and the outlet communicate with respective spaces of a cylindrical rotor mounted on the axle. The casing of the rotor accommodates a bushing arranged coaxially with the hollow axle and is provided with a spiral-shaped band fixed thereon; and with spacers located one after another between adjacent turns of the band in parallel with the hollow axle. The spacers form radial rows and together with the band define slit passages for liquid. The band is made with crimps which run parallel with the hollow axle, while the spacers are located in the crimp tops.
Claims8
A centrifugal liquid purifier comprising:
- a base;
- a vertically extending hollow axle fixed on said base and having an inlet for the liquid to be purified and an outlet for the purified liquid;
- a cylindrical rotor mounted on said hollow axle with a possibility of rotation about the latter;
- a drive for rotating said cylindrical rotor;
- said cylindrical rotor including a top impeller and a bottom impeller, arranged at the opposite ends of said hollow axis, a bushing arranged coaxially with said hollow axis between said top and bottom impellers and coupled with said impellers for joint rotation, a band attached with its one end to said bushing and spiral-like wound thereon, said band being made crimped with crimps running parallel with said hollow axle, spacers located one after another in a radial direction between adjacent turns of said band spiral form in parallel with said hollow axle in crimp tops of said band to form radial rows, slit passages for the liquid being purified defined by said spacers and said band;
- a casing coupled with said top and said bottom impellers and designed to cover said bushing with said band, top and bottom impellers, spaces in said casing located between the ends of said bushing with said band and said top and bottom impellers and communicated one with the inlet and the other one with the outlet of said hollow axle, said spaces communicated with each other via said slit passages, and a pressure disk being mounted in said casing on said hollow axis above the top one of said impellers and designed for pumping the liquid.
