Description

Devices for separating heavy impurities from bulk materials, such as flour, are provided with a rotating cone, into the lower part of which water is fed, which distributes a thin layer to the inner walls of the body under the action of centrifugal force and carries the material being processed, are known.

The described device is intended mainly for the cleaning of heavily clogged flour (sweeps, vyboy). Its feature is that an annular gap was made in the upper part of the cone to separate the lower layer of water with heavy impurities from the upper layer carrying the purified product, and to separate the upper layer of water passing by this gap from the purified product the slit is a porous part of the cone, filtering water.

To evenly feed the mixture into the cone and to pre-separate the large impurities, a rotating disk is mounted under the hopper that serves to feed the material, which carries a cone grid equipped with valves for the periodic release of accumulated large impurities.

The drawing shows a vertical section of the proposed device. Its main part is a rotating rotor consisting of a shaft 10 mounted in sub-bearings 11, on which a disk 2 with a conical net 3 and a conical drum 4 with an annular slot 5 is fixed. In the lower part of the drum 4 there is a nozzle 9. The device case consists of housing J2 serving as a water tank, collection 13 and waste guide 14. In addition, the device has a safety cone 7, a valve 8 and a ring filter 6 located on the conical drum above the slit.

No. 70023-2 -

Before starting work, water is poured into the casing 12 so that the bottom of the nozzle 9 is immersed in it, as shown in the drawing.

After the rotor acquires the necessary rotational speed, water from the casing 12 begins to be sucked through the nozzle 9 and flows in an even layer along the guides of the drum 4 upwards under the action of centrifugal force.

At the same time, the flour 16 to be processed from the stationary bunker / is poured onto the surface of the disk 2, rotates, diverges from the axis of rotation to the sides, falls on the cone grid 3 and, pressing against its walls, flows upwards, penetrating through the mesh holes.

After passing through the holes in the net 3, the flour 16 with impurities gets into the water layer 15, also moving along the cone guide under the action of centrifugal force. During the time of passage along the cone guide of drum 4 to slit 5, the separation of the same solids, taken to flour 16, is carried out in layers corresponding to their specific weight. V-se, that t more desirable than water - metalop: mixes, sand, cement, etc., - flows in the lower layer / 7, s .: the next layer flows water / 5, and flour 16, lightly, passes over the water .

Upon further movement along the direction of the cone of the spent material, i.e., already exfoliated, the material at the time of its passage through the annular gap 5 a layer of heavy impurities and some of the water fall into the slot, and then into the housing 12. The remaining part of the water floating on top of the flour goes to filter 6, where the water is filtered and drains into the tank. Flour 16 behind the filter but the coping guide is poured into collection 13.

Screenings from the grid 3 are delayed by the valve 8. As far as the seedlings of the seedlings are covered, overcoming the valve's mounting, the pathways are discarded, which happens automatically.
