FIRE EXPLOSIVE BULK MATERIAL FEEDING DEVICE Russian patent published in 1994 - IPC

Abstract RU 2008957 C1

FIELD: transportation of fire explosive bulk materials. SUBSTANCE: device has feeder 1 for feeding bulk material into hopper 2 and accumulating of a layer of material having predetermined thickness by means of gate 4. Predetermined thickness is provided by means of a system having levers 8 and counterweights 5. The system prevents blast wave and combustion gas from getting from location of fire into other place. Flash indicator 12 allows ignition to be quickly detected and damper to be shut off. Then feeder 1 is switched off so that closure is completely ready to cut off material feeding pipeline from action of blast wave and combustion gases. EFFECT: enhanced reliability in operation. 5 dwg
