Abstract
The invention discloses a sludge squeezing dehydration device which comprises sludge sedimentation, sludge squeezing, back flushing sediment discharge and filter plate cleaning. A sediment cone funnel is arranged at the lower part of a waste liquid storage tank; the sludge slurry discharged by the backwashing of a filter device settles in the waste liquid storage tank and then is discharged to a squeezer; a sintering filter plate is arranged on a squeezing filter plate at the bottom of the squeezer; through extrusion of compressed air, the liquid is recycled by the sintering filter plate, and the dry sludge is attached to the upper surface of the sintering filter plate; a squeezing bottom plate is opened through an air cylinder or a hydraulic cylinder, and the dry sludge is back-flushed by the compressed air for sediment discharge; after the back flushing, the sintering filter plate is cleaned twice by clean water or clean liquid. The device has the advantages that physicochemical characteristics such as properties, concentration and the like of a chemical solution are not changed, the cleaning effect of the filter plate is good, the squeezed chemical solution is recycled completely, the sludge is recycled in a dry sediment form, and environmental pollution is avoided; meanwhile, without a transmission component, the device realizes low energy consumption and low fault rate and has the advantages of energy conservation and emission reduction.
