SYSTEM FOR AUTOMATED PNEUMO-PULSE TRANSFER OF POWDERED AND GRANULAR MATERIALS Russian patent published in 2019 - IPC B65G53/10 B65G53/40 

FIELD: transportation.

SUBSTANCE: invention relates to pipeline pneumatic conveying of bulk materials and can be used in construction industry, chemical industry, metallurgy, power engineering and related industries. System comprises receiving bins and feed hoppers with pneumatically controlled locking devices located in lower part of bins, loading unit made in the form of a container, the lower cavity of which is connected to the transport pipeline, compressed air source connected to the loading unit by the supply line, in which electromagnetic valve is installed, connected by electric line to automation cabinet, and level sensor. System is equipped with a generator of control pulses, a supply unit with inlet branch pipes connected to the locking devices, and a seat installed at the outlet of the supply unit located in the loading unit. In the upper part of the capacity of the loading unit there is a gate designed so that to enable contact with the seat. Source of compressed air is made in the form of receiver, at that cavities of pneumatic control of locking devices are connected to receiver by supply lines, in which electromagnetic valves are installed. Transport pipeline outlet is connected to two series-mounted flow switches connected by their outlets with precipitators of receiving hoppers.

EFFECT: wider range of equipment for pneumo-pulse transfer of powdered and granular materials.
