Environmental Water Treatment Machine Sludge Dehydrator Sludge Dewatering Equipment
Aufbau principle
1.The main body of the dewatering machine is a filtering device formed by a fixed ring and a traveling ring which are mutually stacked and the spiral shaft penetrates through the filter.
2.The groove formed between the fixed ring and the traveling ring and the pitch of the screw shaft gradually decrease from the concentrated part to the dehydration part.
3.The rotation of the screw shaft drives the sludge from the concentrated part to the dehydration part, and also drives the traveling ring to clean the filter joint to prevent clogging.
4.In the sludge concentration section by gravity concentration after being transported to the dewatering part, in the process of moving forward with the filter joint and the pitch becomes smaller, and the pressure plate barrier under the action of great pressure, volume continued to shrink, to achieve full dehydration.
Dehydration principle
In the sludge concentration section by gravity concentration after being transported to the dewatering part, in the process of moving forward with the filter joint and the pitch becomes smaller, and the pressure plate barrier function, resulting in the pressure, volume continued to shrink, to achieve full dehydration.
Sludge treatment process description
1、Through the flocculation experiment, determine the flocculant dosing ratio. And, if you need to use two kinds of flocculants to flocculation, dewatering machine is provided with two recommendations for the selection of the mixing tank. The sludge flocculation pool to set stirring device, dehydration machine before the operation and operation process, to continue to stir the sludge, ensure the sludge concentration relatively stable.
2、Before running the dewatering machine, should first use of global drug infusion device. The good flocculant solution of polymeric flocculant was diluted 500-1000 times normal. Sludge pump through the sludge, making good flocculant by dosing pump, according to the corresponding proportion and added to the mixed flocculation tank, fully mixing the formation of alum through the mixer, for gravity concentration in the concentration of the filtrate from the filter cracks in the Department of concentrated discharge. Low solid content of filtrate, directly back to the original pool.
3、After the thickening of the sludge along the screw axis forward, under the action of various forces in the dehydration department fully dehydrated. Dehydration filtrate containing high solids, can be returned to the flocculation mixing tank dehydration again.
4、After dehydration mud cake discharged from the mud cake discharge, directly or through the shaftless screw conveyor sent to the mud truck, re-use.
