Description

River course is handled mud and is used folding spiral shell formula hydroextractor

Technical Field

The utility model relates to the field of sewage treatment, in particular to a stacked screw type dehydrator for sludge treatment in a river channel.

Background

In recent years, the stacked screw type sludge dewatering machine is widely applied in China, and the working principle is that when a screw pushing shaft rotates, multiple fixed and movable lamination sheets arranged on the periphery of the pushing shaft move relatively, and water is filtered out from lamination sheet gaps moving relatively under the action of gravity, so that rapid concentration is realized; the concentrated sludge continuously moves forwards along with the rotation of the spiral shaft; along the outlet direction of the mud cake, the pitch of the spiral shaft is gradually reduced, the gap between the rings is also gradually reduced, and the volume of the spiral cavity is continuously contracted; under the action of the outlet back pressure plate, the internal pressure is gradually increased, and under the pushing of the spiral pushing shaft in sequential continuous operation, the water in the sludge is extruded and discharged, so that the continuous dehydration of the sludge is finally realized.

In the prior art, a plurality of fixed ring pieces and movable ring pieces are usually installed on a screw rod in parallel at intervals to form a ring group structure, and then the ring group structure is installed on a connecting plate through a connecting rod and is locked and fixed through a nut. However, in the dehydration process, the ring sheet is stressed greatly, the connecting rod and the nut are not locked firmly, and the loosening phenomenon is easy to occur, so that the gap between the ring sheet and the ring sheet is enlarged, the dehydration effect is influenced, and the ring sheet is easy to deform.
