Volute sludge dewatering machine work flow and dehydration principle Feb 27, 2018

In fact, from the running state of volute sludge dewatering machine to analyze the total work flow can be divided into three stages, namely, concentration, dehydration and self-cleaning. First, during the condensation process, when the spiral screw shaft of the screwdriver is rotated, the multiple fixed laminations located at the periphery of the push shaft undergo relative displacement. Under the action of gravity, the water is filtered out of the relatively moving lamination gap to achieve rapid concentration.

 

Next, with the continuous operation of volute sludge dewatering machine, will gradually achieve the purpose of dehydration. That is, the concentrated sludge moves forward as the screw shaft rotates. Along the exit direction of the mud cake, the pitch of the screw shaft gradually becomes smaller and the gap between the ring and the ring also decreases continuously. At the same time, the volume of the screw chamber is constantly shrinking. Under the action of the back pressure plate at the outlet, its internal pressure is continuously increased. Under the continuous operation of the spiral propeller shaft, the moisture in the sludge is squeezed and discharged, and the solid content of the filter cake is continuously increased, finally the sludge Continuous dehydration.

 

After completing the dehydration, it will then slowly enter self-cleaning. At this moment, the screw shaft of the screwdriver is continuously rotated to promote the continuous rotation of the traveling ring. The device relies on the movement between the stationary ring and the traveling ring to achieve a continuous self-cleaning process, thus easily solving the clogging problems previously encountered.

 

So, the basic structure of volute sludge dewatering machine is what? One of the main parts - stack spiral is mainly composed of a fixed ring and a touring ring stacked on top of each other, the screw shaft formed through the filtration device. For the first part of the enrichment department, after the dehydration department.

 

In fact, the reason that the screwdriver is able to achieve dewatering is mainly because the sludge is concentrated in the concentrating section and then transported to the dewatering section. And in the process of its advancement of the filter and the pitch is getting smaller, but also by the back pressure plate blocking effect, which will have a great internal pressure, the volume continues to shrink, to achieve the purpose of adequate dehydration.
