The invention belongs to the field of sludge treatment equipment and discloses a high-efficiency sewage treatment device, for solving the problem that the conventional centrifugal machine is easily corroded because the sludge cannot be totally discharged out of a drum. The high-efficiency sewage treatment device comprises a rack, wherein a drum is arranged on the rack by virtue of a bearing; a drive motor used for driving the drum to rotate is arranged on the rack; a hollow structure is formed inside the drum; the drum comprises a linear section and a conical section; screw blades are arrangedat the peripheries of the linear section and the conical section; a feeding hole is formed in the conical section; a housing arranged on the rack is arranged at the periphery of the drum; a liquid phase outlet is formed in the housing of the linear section; a solid phase outlet is arranged on the housing of the conical section side; a discharging hole is formed in the linear section; a rotating shaft is arranged in the drum; second screw blades are arranged at the periphery of the rotating shaft; and the rotating shaft extends out of the conical section and is provided with the feeding hole.
Description
technical field [0001] The invention belongs to the technical field of sludge treatment equipment, and in particular relates to a high-efficiency sewage treatment device. Background technique [0002] The important device in the sewage treatment plant is the sludge dewatering machine. The working process of the sludge dewatering machine is: the sedimented sludge from the sludge thickening tank is crushed by the sludge cutting machine, transported by the sludge feed pump, and flocculated The prepared medicine liquid sent by the chemical dosing system is combined together, mixed into the centrifugal dehydrator, the sludge is separated by the dehydrator into solid / liquid two phases, and the liquid phase (clarified liquid or separated liquid) is directly discharged or sent to the sedimentation The solid phase (dewatered sludge) is discharged by the screw conveyor. [0003] There are also many technical documents about sludge dewatering machines in the prior art. For example, th...
