Working principle of screw stacking machine:
The working principle of the
Snail Stacking Machine is divided into three parts: concentration, dehydration, and self-cleaning.
Concentration part of snail stacker:
When the spiral push shaft rotates, the multiple solid and active laminations located on the periphery of the push shaft move relative to each other. Under the action of gravity, water is filtered out from the gaps between the relatively moving laminations to achieve rapid concentration.
Dehydration part of snail stacker:
The concentrated sludge continues to move forward as the spiral shaft rotates; along the direction of the mud cake outlet, the pitch of the spiral shaft gradually becomes smaller, the gap between the rings also gradually becomes smaller, and the volume of the spiral cavity continues to shrink; Under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Driven by the continuous operation of the spiral push shaft, the water in the sludge is squeezed out, and the solid content of the filter cake continues to increase, ultimately achieving continuous dehydration of the sludge.
Self-cleaning part of snail stacking machine:
The rotation of the spiral shaft drives the moving ring to continuously rotate. The equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thereby cleverly avoiding the common clogging problem of traditional dehydrators.
The main body of the dehydrator is a filtration device formed by stacking fixed rings and moving rings, with a spiral shaft running through it. The front section is the concentration section, and the rear section is the dehydration section.
The filter gap formed between the fixed ring and the moving ring and the pitch of the spiral shaft gradually become smaller from the concentration part to the dehydration part.
The rotation of the screw shaft drives the sludge to be transported from the concentration part to the dehydration part, and at the same time, it also continuously drives the swimming ring to clean the filter seams to prevent clogging.
