Abstract
The utility model discloses mud extrusion equipment comprising a mud collecting trough and a mud pressing roller, wherein the top of the mud collecting trough is open; a cavity accommodating wet sludge is formed in the mud collecting trough; a plurality of mud distributing holes are formed in the bottom wall of the mud collecting trough; the mud pressing roller is arranged in the cavity in the longitudinal direction of the mud collecting trough, and can pivot around the longitudinal central line of the mud collecting trough; and the cross section of the mud pressing roller becomes smaller and smaller from the top down. As the mud pressing roller can pivot in the cavity, the wet sludge in the cavity can be extruded to a sludge drying device below the mud collecting trough through the mud distributing holes in a bar-shaped manner, which greatly enlarges the contact area between the wet sludge and high-temperature gas, improves the heat transmission efficiency, and can further shorten the drying time of the wet sludge in the next process. The utility model further discloses a sludge treatment system with the mud extrusion equipment.
