Environment-friendly silt clearing device of sewage settling tank

Abstract

The invention discloses an environment-friendly silt clearing device of a sewage settling tank in the technical field of silt clearing. The device comprises four support claws, wherein a lifting rackis arranged at the top of each support claw, the top of each lifting rack is sleeved with a fixing loop bar, a gear matched with each lifting rack is arranged in the corresponding fixing loop bar, a fixed water return tank is arranged at the top of the fixing loop bar, four connecting rods are arranged at the bottom of the fixed water return tank, a silt collecting sleeve is arranged at the bottoms of the connecting rods, silt collecting blades are arranged in the silt collecting sleeve, a threaded shaft sleeve is arranged in the center of the silt collecting blades, a material lifting casingpipe is penetrate through the center of the fixed water return tank, a spiral material lifting rod is arranged in the material lifting casing pipe, the top of the fixed water return tank is sleeved with the silt collecting tank, and the material lifting casing pipe penetrates through the silt collecting tank and extends into the silt collecting tank. The device is simple in structure and can rapidly clear silt in the sewage settling tank.

Description

technical field [0001] The invention relates to the technical field of sludge cleaning, in particular to a sludge cleaning device for an environment-friendly sewage sedimentation tank. Background technique [0002] Since sewage pipes are used to collect domestic sewage and industrial waste water, it is easier to collect various garbage, floating objects and sediment in the pipes. Although most of the silt can be removed through dredging and maintenance, it is inevitable that a small amount of sediment will Pipelines pile up downstream and eventually settle in sewage sedimentation tanks. The sedimentation silt that accumulates in the sedimentation tank will occupy a large amount of space in the sedimentation tank and reduce the water storage capacity. [0003] The existing silt discharge equipment will be discharged together with the sewage, and some sewage needs subsequent treatment, and direct discharge will cause pollution. Only manual cleaning of the accumulated silt in ...
