TURBOSEPARATOR Russian patent published in 2004 - IPC

FIELD: pulp-and-paper industry, in particular, equipment used at initial stages of preparing paper pulp from waste paper, that is, for additional coarse cleaning of waste paper mass from light and heavy contaminating inclusions and simultaneously for additional dismissal thereof.

SUBSTANCE: turboseparator has vertical conical casing, conical chamber positioned in conical casing and adapted for receiving of waste paper mass for further processing thereof, tangential branch pipe built-in at casing smaller base and designed for tangential feeding of waste paper mass into receiving chamber, drop cover arranged at conical casing larger base and equipped with branch pipe adapted for removal of waste paper mass comprising light contaminating inclusions from receiving chamber, said branch pipe being built-in at central part of drop cover. Turboseparator is further provided with at least one branch pipe arranged in lower part of receiving chamber and adapted for discharging of heavy contaminating inclusions therefrom, perforated sieve arranged at smaller base of conical casing and adapted for cleaning of waste paper mass from contaminating inclusions, and clean waste paper mass receiving chamber equipped with branch pipe for removal of clean waste paper mass from said chamber. Turboseparator has bladed rotor mounted in conical receiving chamber at site adjoining sieve surface in axially aligned relationship with said chamber and sieve, and shaft mounted in axially aligned relationship with respect to conical receiving chamber and extending through sieve central part. Bladed rotor is mounted at one end of shaft and other end of shaft is kinematically connected with electric engine.

EFFECT: improved quality of cleaning of waste paper mass owing to increased selective capacity of turboseparator in cleaning of waste paper mass from light and heavy contaminating inclusions and reduced consumption of power.
