Reciprocating type laminated spiral solid-liquid separator

Abstract

The invention discloses a reciprocating type laminated spiral solid-liquid separator. The separator comprises a support frame, a filter cavity assembled with the support frame, a spiral shaft mountedon the support frame and penetrating through the filter cavity, and a driving device mounted on the support frame, a feeding port and a discharging channel are arranged at two ends of the filter cavity, the filter cavity comprises a first closed movable ring sheet group and a second closed ring sheet group which is inconsistent with the first closed movable ring sheet group in motion states, and the two closed ring sheet groups are alternately stacked to form the filter cavity. A gasket is arranged between every two adjacent closed ring sheets of at least one of the two closed ring sheet groups, and the thickness of the gasket is larger than that of each closed ring sheet of the remaining closed ring sheet group to make a filter gap formed between the adjacent closed ring sheets. The reciprocating type laminated spiral solid-liquid separator adopting the above technical scheme has the advantages of high filtering efficiency, good filtering effect, uniform driving force distribution andlong service life.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation devices, in particular to a reciprocating lamination type solid-liquid separator. Background technique [0002] The solid-liquid separator is mainly used for sludge dewatering. The prior art laminated spiral sludge dewatering machine is a filter cavity formed by stacking a fixed ring and a movable ring. The fixed ring is fixed on the pillar and remains in a fixed state. Changes in the overlapping position can be generated to keep the filter seam unobstructed and not clogged. However, the movable ring is driven by the screw shaft in the filter cavity. Because of the continuous contact operation, the wear between the screw shaft and the movable ring is caused. Moreover, there is only one screw shaft in the filter chamber, so some easily compacted and entangled sludge will be blocked in the chamber, which will affect the stable operation of the equipment.

Problems solved by technology

However, in the driving mode of this structure, between the driving end with eccentric device and the guiding end for limiting, because of the frictional resistance in the limiting hole, the movable ring will be deformed during operation, and the larger the equipment , the larger the movable ring, the larger the hollow span of the ring, and the extrusion of the two ends will easily cause the deformation or even breakage of the movable ring

In addition, due to the inconsistency of the motion trajectories at both ends, that is, the limit end moves up and down in a straight line, while the guide end makes left and right pendulum movements, resulting in poor permeability in the upper half of the filter cavity, which affects the filtering effect and efficiency.

In addition, due to the relative disorder of the motion trajectory, the design of the ring will be irregular and not uniform enough. On the one hand, it will affect the strength of the ring, and on the other hand, it will also have a certain impact on the filtering effect and efficiency.

In addition, because the positioning shaft is allowed to move freely in a straight line in the limiting hole, it will inevitably cause a certain amount of wear between the positioning shaft and the limiting hole.
