Sludge mixing, concentrating and discharging integrated tank

Abstract

The invention discloses a sludge mixing, concentrating and discharging integrated tank. The sludge mixing, concentrating and discharging integrated tank comprises a tank body, a stirring mechanism anda driving mechanism, wherein the stirring mechanism is mounted in the tank body; the driving mechanism is used for driving the stirring mechanism; the inside of the tank body is successively dividedinto a mixing and condensing section, a mixing and flocculating section and a precipitating and separating section by a first pair of partitions and a second pair of partitions from top to bottom; andthe stirring mechanism comprises a stirring shaft, a first kind of paddles, a second kind of paddles, a third kind of paddles and a fourth kind of paddles, the stirring shaft penetrates through the tank body vertically, the first kind of paddles, the second kind of paddles, the third kind of paddles and the fourth kind of paddles are connected with the stirring shaft from top to bottom, and the sizes of the first kind of paddles, the second kind of paddles, the third kind of paddles and the fourth kind of paddles are gradually reduced. The sludge mixing, concentrating and discharging integrated tank is small in occupied area, mixing, flocculating and separating functions are integrated, the time required for precipitating and separating is shortened, the treatment efficiency and the separating efficiency are greatly improved, and the running cost is reduced.

Description

technical field [0001] The invention relates to a mixed flocculation sedimentation mud-water separation device in a sludge treatment system, in particular to an integrated tank for sludge mixing, concentration and discharge, which belongs to the field of equipment related to sludge treatment and is suitable for municipal, chemical, metallurgy, papermaking, food, etc. various industries. Background technique [0002] Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. In the conventional sludge treatment system, the sludge is continuously sent to the cement structure storage thickening tank with a large area through the pump and the pipeline, and the sedimentation treatment is carried out in the thickening tank for a long time, and the muddy water will not be completely realized synchronously. The separated turbid liquid is recovered to the front stage of treatment and recycled again. Different treatment methods are adopted according t...
