Description
Technical Field
The invention relates to the technical field of solid-liquid separation devices, in particular to a reciprocating laminated solid-liquid separator.
Background
The solid-liquid separator is mainly used for sludge dewatering. The laminated spiral sludge dewatering machine in the prior art is a filtering cavity formed by laminating a fixing ring and a movable ring, the fixing ring is fixed on a pillar, the fixing state is kept immovable, and the filtering seam is kept smooth and unblocked by relying on the movement of the movable ring and the change of the overlapping position between the fixing ring and the filtering cavity. However, the movable ring is driven by the spiral shaft in the filtering cavity, and the spiral shaft and the movable ring are abraded due to continuous contact operation. And only one spiral shaft is arranged in the filtering cavity, so that some sludge which is easy to harden and wind is blocked in the cavity, and the stable operation of the equipment is influenced.
Chinese patent 201720385178.1 discloses a multi-shaft laminated spiral solid-liquid separator for pendulum motion, wherein a filter cavity is formed by staggered fixed rings and movable rings; the cavity is internally provided with two or more screw shafts which are arranged side by side, the movable ring is driven by an eccentric device at one end and limited by a guide device at the other end, the movable ring is not in contact with the screw shafts, the movable ring is displaced and overlapped with the fixed ring, the filtering gap between the fixed ring and the movable ring is kept smooth, and the technical problem that the sludge is easily hardened and wound to block the cavity is solved. However, in the driving mode of the structure, the driving end with the eccentric device and the guide end for limiting are arranged between the driving end and the guide end, because of the friction resistance in the limiting hole, the movable ring is deformed in the operation process, the larger the equipment is, the larger the movable ring piece is, the larger the hollow span of the ring piece is, the two ends of the ring piece are extruded in opposite directions, and the movable ring piece is easily deformed or even broken. In addition, due to the fact that the motion tracks of the two ends are not consistent, namely the limiting end moves up and down linearly, and the guide end moves left and right in a pendulum motion mode, the permeability of the upper half part of the filtering cavity is poor, and the filtering effect and efficiency are affected. In addition, because of the relative disorder of the motion trail, the ring sheet can be designed to be irregular and not uniform enough, on one hand, the strength of the ring sheet is influenced, and on the other hand, certain influence is generated on the filtering effect and the filtering efficiency. In addition, since the positioning shaft is allowed to freely perform linear motion in the limiting hole, certain abrasion is inevitably generated between the positioning shaft and the limiting hole.
therefore, many aspects need to be improved.
