DEVICE FOR REMOVING MATERIAL FROM SPACE EXPOSED TO GAUGE PRESSURE Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to device designed for removing hard material, particularly, for removing finely hard material formed in process of filtration from space exposed to gauge pressure. Said device has members to deliver material to be treated into process taking place in space exposed to pressure and to evacuate products formed in said process from space exposed to gauge pressure. According to invention discharge holes are made in discharge unit connected to space exposed to gauge pressure. Discharge holes serve to let out hard material which should be removed from space exposed to gauge pressure. Said discharge holes have at least one control member to regulate amount of material in discharge unit to be evacuated. EFFECT: simplified design, automatic functioning depending on working pressure and material flow. 10 cl, 3 dwg
