Steel mill sludge settling pond sludge suction equipment

Abstract

The invention discloses steel mill sludge settling pond sludge suction equipment, which comprises rails built on the two symmetrical edges of a settling pond, a cart walking mechanism capable of moving on the rails, and a water collecting groove parallel to the rails and built on the settling pond, wherein a submersible stirring wear-resistant slurry pump ascends or descends according to the depthof the settling pond, a motor controls a motor shaft to rotate, the motor shaft drives stirring blades to rotate, the blade edges of the stirring blades are processed into cutting edges, the cuttingedge is flush with the opening of a horn shell, the stirrer blades are used for stirring sticks, gravel carbon chips, sludge residue and other high-density precipitates and cutting imported debris, when the stirring blades rotate, the slurry in the settling pond is stirred, the slurry containing oxide scales and sucked in the horn shell is conveyed into a liquid flowing groove through a suction pump, the liquid in the liquid flowing groove flows into the water collecting groove, the water collecting groove integrally discharges water and sludge into a water pool for unified treatment, and themoving direction of a movable sludge suction vehicle is perpendicular to the moving direction of a walking truss, so that the sludge in the plane of the settling pond can be cleared away.

Description

technical field [0001] The invention relates to a sludge suction equipment for a sedimentation tank, in particular to a sludge suction equipment for a steel mill sludge sedimentation tank. Background technique [0002] Generally, in the steel rolling production process of steel mills, the wastewater generated in the pickling and etching process will produce a large amount of metal oxide components (content about 15% to 60%) after adding calcium salt chemical coagulation, precipitation and dehydration treatment. Inorganic sludge with calcium fluoride (content about 15% to 45%), and if these sludges want to directly reduce the metal oxides inside, the cost is very high and it is not economical; moreover, some steel The plant will provide the sludge to the cement plant for use in cement. However, the amount of sludge that can be added to cement is much smaller than the amount of sludge produced by the steel plant, so the steel plant also faces the problem of dealing with excess...
