SLUICE GATE FOR LOOSE MATERIALS Russian patent published in 2015 - IPC B65G53/46 B07B11/06 

FIELD: machine building.

SUBSTANCE: sluice gate for the loose materials contains casing with cover installed under the silo, and honeycomb rotor with drive. The honeycomb rotor is installed in casing eccentrically creating semi-ring slits, under it the vacuum receiver is installed. The honeycomb rotor blades are installed with possibility of movement in its slots, thus ensure possibility of the pneumatic drive of the honeycomb rotor. The honeycomb rotor blades are made out of the elastic material, for example rubber. Possibility of the blades exit from the honeycomb rotor slots in zones of the loose material feeding from the silo, and it output to the receiver is limited by the shoulders on the unloading branch of the silo and on branch of the loose material exit from the sluice gate to the receiver. Each blade of the honeycomb rotor is made having stepped configuration, by wide part it is installed in expansion of the honeycomb rotor slot with creation of the shelf securing it in the slot against fall out. The honeycomb rotor blades are spring-loaded in its slots. Casing is equipped with cover having semi-ring shape, it is installed in guides of the silo and receiver with possibility of movement and locking.

EFFECT: exclusion of air overflows and simplified external drive of the drum dosing unit, simultaneously being sluice gate in process trains of the loose materials processing.
