METHOD FOR BULK AUTOMATIC DISPENSING OF BULK MATERIALS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC G01F13/00 

FIELD: measuring equipment.

SUBSTANCE: invention can be used for repeated measurement and dispensing of specified volumes of loose bodies from a tank irrespective of weight of bodies and method of their supply. Essence of the invention consists in the fact that the method of discrete automatic volumetric dosing of bulk materials includes connection to it through an air filter of the suction line of the air blowing unit, rarefaction is created with respect to external pressure, as a result of which the container is filled with loose material and, when a certain vacuum is achieved, material is unloaded from the container, at that, for material unloading, suction line is disconnected from container and connected to external pressure area, blowing line of air blowing unit is connected to capacity, and after emptying the vessel, upon a signal of achieving a minimum excess pressure in it, a pressure line from the container is disconnected and connected to an external pressure region, and a suction line of the air blower unit is connected to the container.

EFFECT: possibility of increasing quick operation and failure-free operation of automatic dispenser of bulk materials with simultaneous reduction of power consumption for dispensing process.
