During the operation of the Automatic sludge dewatering machine, when the spiral push shaft rotates, the multiple solid laminated sheets which are arranged at the periphery of the push shaft are relatively moved during operation, and the water moves from the relative movement under the action of gravity. Filtration in the gap of the sheet for rapid concentration. The concentrated sludge moves forward with the rotation of the screw shaft; along the exit direction of the mud cake, the pitch of the screw shaft gradually becomes smaller, the gap between the ring and the ring gradually becomes smaller, and the volume of the spiral cavity shrinks continuously; Under the action of the back pressure plate at the outlet, the internal pressure is gradually enhanced. Under the continuous driving of the spiral push shaft, the water in the sludge is squeezed out, and the solid content of the filter cake is continuously increased, and finally the continuous dewatering of the sludge is realized.
The self-cleaning of the automatic sludge dewatering machine, the rotation of the screw shaft during operation, pushes the swimming ring to rotate continuously during operation, and its equipment mainly relies on the movement between the fixed ring and the swimming ring to achieve continuous operation. The self-cleaning process can ingeniously avoid the clogging problem that is common in traditional dewatering machines.
Automatic sludge dewatering machine is widely used
1. Suitable for sludge in municipal sewage, food, beverage, chemical, leather, welding consumables, papermaking, printing and dyeing, pharmaceutical and other industries.
2. Suitable for dehydration of high and low concentration sludge. When dewatering low concentration (2000mg/L~) sludge, it is not necessary to build a concentration tank or a storage tank, reduce construction cost, reduce phosphorus release and anaerobic odor generation.
Design requirements for automatic sludge dewatering machine
1. Compact design, the dehydrator contains electric control cabinet, metering tank, flocculation mixing tank and dehydrator body.
2. Small footprint, easy to repair and replace; small weight, easy to handle.
