    A stationary chamber having a perforated peripheral wall contains an axial rotor having rubber-like radial carrier blades which, as the rotor rotates, are indented at their outer edges by guide means having helical turns extending along said peripheral wall. A passage allows ambient gas to enter the chamber so that the rotor's action on a liquid-solids mixture entering a first part of the chamber maintains a free liquid surface therein. The carrier blades and rotor coact with the helical turns to carry a liquid-bearing cake of the solids through the free liquid surface and thence through a second part of the chamber to a solids outlet, during draining of liquid from the cake through the perforated peripheral wall.

    (54) DEVICE FOR SEPARATION OF SUSPENSION
    one
    The invention relates to devices for separating suspensions into fractions in the field of centrifugal forces.
    A device for dividing a suspension into fractions is known, comprising a housing, 5 having chambers for withdrawing separated fractions and a nozzle for supplying the suspension, a conical perforated shell fixed in the housing motionless, facing a smaller base upwards, and a rotor 1 mounted inside the shell a cone-shaped body, on the outer surface of which the screw is fixed, and to the lower end wall, locks are attached. A narrow channel is formed between the rotor and the wall of the perforated shell, which is directed but at a helical line to the outlet opening. The initial suspension enters the gap between the shell and the rotor and moves 20 to the screw channel as the rotor rotates. By the action of centrifugal force, the liquid passes through the perforation of the shell, and the solid phase with the residual liquid moves upward to the discharge hole and is thrown into the chamber. ON FRACTIONS
    In the known device, a free surface of the liquid is not created through which solid particles moving to the outlet can move, therefore solid particles are removed with a relatively large amount of liquid phase.
    The purpose of the invention is to increase the degree of dehydration of the solid phase.
    For this, the proposed device is provided with an additional cone-shaped shell, rigidly connected with a large base with the main one to form a suspension chamber tapering towards the inlet and exit of the solid phase of the separation chamber, on the inner surface of the main shell a solid guide plate is attached along the helix; fortified on the shaft of the blades.
    The rotor is provided with an auger for feeding the suspension inside the separation chamber.
    In the chamber of solid phase on the rotor shaft fortified blades.
    FIG. 1 schematically shows the proposed device, a longitudinal section with
    partial section of the rotor; in fig. 2 is a section along A-A of FIG. one.
    A device for dividing a suspension into fractions includes: a housing 1 having chambers 2 and 3 for outputting solid and liquid phases, vertically fitting 4 in the lower part of the housing for supplying the suspension; fixedly located in the housing cone-shaped perforated shell 5, with the smaller base facing up; an additional cone-shaped perforated shell 6, rigidly connected with a large base to the main body with the formation of a suspension narrowing towards the inlet and exit of the solid phase of the separation chamber 7; a rotor consisting of 8 blades 9 mounted on a shaft.
    On the inner surface of the main shell 5, a guide plate 10 for the solid phase is strengthened along a helix. The rotor is provided with a screw 11 for supplying the suspension to the inside of the separation chamber 7. In the chamber 2 for removing the solid phase on the rotor shaft, the blades 12 are fixed.
    The blades 9 are attached to the shaft 8 by means of the plates 13 and axially along the entire chamber 7, and in the radial direction they reach the walls of the shells.
    The proposed device works in the following manner.
    The screw 11 feeds the slurry from the reservoir 14 into the lower part of the chamber 7, formed by an additional shell 6. The rotor blades 9 capture the slurry and cause it to rotate along the sides of the shells. Under the action of centrifugal force, the fluid passes through the perforations of the shells into chamber 3, and the solid phase, concentrating, moves along the axis towards the outlet 15. Inside the chamber 7 a free surface 16 of fluid forms, which is the boundary between the liquid and the gaseous medium, access which is provided to the chamber through the channels between the blades 12. It is necessary that the surface 16 of the liquid reaches the wall of the chamber 7 approximately in the transition zone from the shell 6 to the shell 5.
    Where the surface 16 of the liquid reaches the wall of the chamber 7, a solid particle containing liquid is formed. This crust passes through the surface of the liquid to the upper part of chamber 7. The rotor blades 9 move the cake formed along the guide plate 10 to the outlet 15, while the centrifugal force further dehydrates the crust. The vanes 12 eject the solid phase from chamber 2. The liquid phase from chamber 3 is removed through the outlet channel 17.
    The proposed device was tested in the separation of liquid manure on the solid and liquid phase. The solid phase was so dry and porous that it could be used to make compost without further drying.
