The origin and working principle of the sludge screw dewatering machine and its composition

- Jul 09, 2018-

The sludge screw dewatering machine is one of the dehydrators and has a wide range of applications.

The origin of the sludge screw dewatering machine is the filtration equipment, which appeared in the epic European industrial revolution period. The specific types are filter presses, leaf filters and spiral filters, mainly used in oil press and minced meat. Squeeze dewatering and filtration of fish and shrimp waste, and later used in sludge dewatering and other industrial wastewater treatment. Later, with the continuous development of spiral filtration technology, and in order to solve and avoid the problem of blockage, the machine of the sludge screw dewatering machine appeared. Moreover, from the current point of view, the three aspects of the spiral shaft, the wear-free structure and the industry-specific models are constantly being explored.


The application of the sludge screw dewatering machine mainly includes municipal wastewater treatment projects, as well as water treatment systems in the petrochemical, light industry, chemical fiber, paper, pharmaceutical and leather industries. Moreover, the use of this device can bring some benefits to users and benefit users.


Working principle of the sludge screw dewatering machine

Concentration: When the screw pushes the shaft to rotate, the live laminations on the periphery of the shaft move relatively, and the water is filtered out from the lamination gap by gravity to achieve rapid concentration.


Dewatering: After the concentrated sludge is continuously pushed forward under the spiral shaft, along the direction of the mud cake outlet, at the same time, the water in the sludge is continuously squeezed out, so that the solid content of the filter cake is continuously increased to achieve pollution. Continuous dewatering of the mud.


Self-cleaning: The rotation of the screw shaft is used to push the continuous rotation of the swimming ring, and the self-cleaning operation of the device is performed by the movement between the fixed ring and the moving ring, so that the problem of clogging can be well avoided.


Structural composition of the sludge screw dewatering machine

The sludge screw dewatering machine is a kind of dewatering machine. In the specific structure, it is an important part of the snail body. The stacking screw body has two parts of a fixed ring and a swimming ring, and they are laminated to each other. A screw shaft is formed therein to form a filtering device, the front section is a concentration section, and the rear end is a dewatering section.
