Abstract
PURPOSE: To ensure the lowering of water content, while expanding the range of applicable sludge, through separation of the srpernatant liquid and compressed dehydration of the cake by means of a sludge cover mounted in the upper opening of a storage tank.
CONSTITUTION: One end of a sludge cover 15, made of soft rubber, provided with a filter cloth 16 on the open bottom thereof is mounted to a frame body 18 hoisted with a lifting strap 17 connected to a hydraulic cylinder 12. The cover 15, free to ascend or descend, is to be tightly fitted into the upper opening of a storage tank 8. After the completion of sludge supply, the water level is lowered as the supernatant liquid is drained. WIth exhaustion of the supernatant liquid, the filtratepasses through a sludge sediment. At this point, a valve 31 is opened and pressure is applied to the inside of the tank 8 through the cover 15, producing an compressed dehydration action, whereby slightly remaining water in the cake can be efficiently into an airtight separation tank 13 through a filter cloth 1, a porous plate 5 vacuum chamber 6
