Abstract
The invention discloses tap water sludge separation equipment achieving thorough residue discharge.A drum is horizontally arranged, a spiral push barrel is located in the drum and is coaxial with the drum, and the interior of the drum is separated into a feeding cavity located in the spiral push barrel and a separation cavity between the spiral push barrel and the drum through the spiral push barrel.A plurality of rib plates distributed along the circumference are arranged in an extruding cavity of the drum and extend from a feeding port to a discharging port.The drum and the spiral push barrel are driven by a first motor and a second motor respectively.Slurry to be separated enters the feeding cavity and then enters the separation cavity from distributing holes, and the slurry is separated into a solid phase located on the outer ring and a liquid phase located in the middle in the separation cavity along with rotation of the drum.The solid phase and the liquid phase of tap water sludge can be efficiently separated; due to the fact that the rib plates are arranged in the extruding cavity, when a second spiral blade extrudes the solid-phase sludge, the pressure and angle are changed, the friction force and drying pressure of material residues are increased, and the solid-phase sludge can be discharged thoroughly.
