Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation devices, in particular to a clogging-clearing non-contact multi-layer laminated solid-liquid separation device. Background Technique

[0002] At present, solid-liquid separation devices are used in some sewage treatment plants, cement plants, chemical plants, farms, tunnel mud treatment and other places. It is based on the solid-liquid separation principle of flocculation and agglomeration and is used for dehydration.

[0003] The existing laminated screw-pushing sludge dewatering machine is composed of a multi-layer stack of fixed ring plates, gaskets and movable ring plates to form a filter cavity. The rotation displacement difference of the spiral shaft blades is relied on to drive the movement of the movable ring, and then the position changes between multiple fixed rings to keep the filter gap unblocked; such movement causes the spiral shaft blades to continuously rub against the movable ring plates, thereby greatly reducing the service life of the spiral shaft and the movable ring plates; moreover, when the spiral shaft pushes the movable ring plate to move, it will also cause friction between the movable ring plate and the fixed ring plate and the gap to deviate to one side. The consequence of this is that the movable ring and the fixed ring rub against each other, reducing the service life and causing mud leakage, which will further lead to an increase in the moisture content of the discharged sludge.

[0004] Secondly, the spiral shaft conical blades are located in the dehydration and extrusion section of the filter cavity. When the sludge is pushed to the conical part of the cavity, the internal pressure will suddenly increase, which is very easy to cause sludge blockage and affect the stable operation of the equipment. It is very troublesome to deal with this problem because the filter gap is very small, and even high-pressure water cannot wash the blocked sludge in the cavity. Sometimes, it is necessary to remove the main shaft motor and then pull out the spiral shaft from the cavity to solve the blocked sludge. Content of the Utility Model
