CONTINUOUS-ACTION CHAMBER PUMP FOR PNEUMATIC TRANSPORTATION OF LOOSE MATERIAL Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: continuous-action chamber pump has vacuum vortex or jet pump installed on air supply pipe to use energy of air delivered along air supply pipe for building rarefaction in its suction zone. Pump has also suction pipelines with shutoff valves, each connected by one end with aerating device of corresponding chamber and by other end, with suction zone of vacuum pump to suck air out of chamber being loaded. Loaded discharge shutoff device of each chamber has scavenging nozzle communicating with delivery air line of corresponding chamber through distributor of air delivered into chamber. EFFECT: increased capacity and reliability of pump, reduced specific air consumption for transportation. 2 cl, 1 dwg
