Quick water filtering device for sludge dewatering

Abstract

The invention discloses a quick water filtering device for sludge dewatering. The device comprises an outer shell, a stirring shaft, a base and a fan blade frame, an inner shell is also arranged in the outer shell, the inner shell and the outer shell are concentrically arranged at an interval, and the stirring shaft is arranged in the inner shell; the inner shell and the outer shell are jointly and fixedly installed on a support, a cavity is formed in the support, a plurality of driving cams are arranged in the cavity, a plurality of jacking columns are movably arranged on the side faces of the driving cams, and each jacking column is driven by one driving cam. An elastic sheet film is further arranged at the upper end of the jacking columns so that a third motor stirs at a high speed andenters a stirring stage, after the stage is completed, the rotating speed of the third motor is reduced, a mud-water mixture located in the inner shell enters a rubber plume stage, the stirring stageand the rubber plume stage can be completed step by step only in the inner shell, and sludge can quickly enter a solid state; the time of the whole process is shortened, and the dehydration efficiencyis improved.

Description

technical field [0001] The invention relates to a sludge dewatering device, in particular to a rapid water filtration device for sludge dewatering. Background technique [0002] Sludge dehydration is a sludge treatment method that removes water from fluidized primary, concentrated or digested sludge and converts it into semi-solid or solid sludge. Dehydration methods mainly include natural drying method, mechanical dehydration method and granulation method. [0003] Among them, the most widely used dehydration method is the mechanical dehydration method. In the mechanical dehydration method, the cement mixture is guided from the collection tank to the conditioning and stirring tank, and the polymer coagulant is added, and it is carried out under the coagulation effect of the polymer coagulant. Stir quickly so that the coagulant and the substances in the cement mixture can fully react, and then guide the reacted cement mixture into the rubber plume pool, so that the solid pa...

[0003] Among them, the most widely used dehydration method is the mechanical dehydration method. In the mechanical dehydration method, the cement mixture is guided from the collection tank to the conditioning and stirring tank, and the polymer coagulant is added, and it is carried out under the coagulation effect of the polymer coagulant. Stir quickly so that the coagulant and the substances in the cement mixture can fully react, and then guide the reacted cement mixture into the rubber plume pool, so that the solid particles produced by the reaction can collect water and become larger, and then the mud-water mixture carrying the solid particles Guided to the separation mechanism for final dehydration treatment; and this dehydration process is relatively cumbersome, and the frequent replacement of the treatment tank will also disturb the muddy water that has initially formed a separation layer, reducing the effect of muddy water separation, especially in the stirring stage and Step-by-step processing of the rubber plume stage, which in turn leads to inefficiencies in sludge-water separation
