MIXER Russian patent published in 2012 - IPC C05F3/06 B01F13/00 

FIELD: machine building.

SUBSTANCE: mixer includes capacities for components, unloading conveyor and mixing drum. Capacities for components are made in the form of sectors in common bunker. Bunker is made in the form of cylinder or polyhedron and installed on skids. Skids are equipped with rolling bodies or pneumatic wheels installed in two rows. Mixing drum is made in the form of a cylinder installed at sharp angle to horizontal plane. On central shaft of drum there rigidly fixed are blades installed in a staggered order along screw line. Vibrators are fixed from below at the bottom of each sector. Batcher for each component consists of a damper with screw drive from electric motor. Bottom of each sector is independent and fixed on shock absorbers. Gaps between bunker walls are sealed with fabric crosspieces that are rigidly attached to the bunker wall and bottom. Unloading conveyor is made in the form of a screw and hinged with possibility of adjusting the inclination angle by means of a rod with single-acting hydraulic or pneumatic cylinder to the housing of mixer and to the conveyor. Lower part of conveyor is hinged to mixing drum. Vertical pneumatic lines with guide nozzles rigidly attached to pneumatic lines are routed on the bunker walls and crosspieces between sectors with similar pitch. Pneumatic lines are integrated to a common pneumatic system with compressor, electric drive to it and system of safety and reducing valves with possibility of providing the pulse mode of air supply to each sector of bunker with its maximum operating pressure and pulse intervals. Prismatic bunker divided into several compartments with batching devices of fertilisers and concentrated additives to the mixture is installed above the mixing drum along its symmetry axis.

EFFECT: such design will allow improving the mixer efficiency.
