Compared with the volute dewatering press, under the same processing conditions, the stack screw dewatering machine not only works more efficiently, but also saves 85% of energy, and its space is only one-half. The stacking screw dewatering machine is especially suitable for processing pressure oil sludge flocculation in food processing plants.
In the structural design, the volute dewatering press can be designed with a detachable independent structure and equipped with five axes, which can be stopped or run on several axes when the amount of blowdown is reduced. Each axis runs independently, overhaul, as long as you stop to overhaul a single host. During the enrichment phase, when the screw pushes the shaft to rotate, the multiple solid laminations disposed on the periphery of the push shaft move relatively, and under the action of gravity, water is filtered out from the relatively moving lamination gap to achieve rapid concentration.
The concentrated sludge moves continuously with the operation of the stacking screw dewatering machine. Under the action of the back pressure plate at the outlet, the internal pressure is gradually increased. Under the continuous driving of the screw pushing shaft, the water in the sludge is squeezed out. The solid content of the filter cake is continuously increased, and the continuous dewatering of the sludge is finally achieved.
