## Abstract

Disclosed is a multi-shaft laminated spiral solid-liquid separator with a pendulum motion, the separator comprising fixed rings, movable rings and screw shafts, wherein each of the screw shafts is provided with the fixed rings and the movable rings in a staggered arrangement in a radial direction to form a cavity; there are two or more screw shafts arranged in the cavity side by side, and the fixed rings and the movable rings are in the form of an annular structure with two rings staggered and communicated or multiple rings staggered and communicated.

## Claims

### Claim 1

A multi-shaft laminated spiral solid-liquid separator with a pendulum motion, comprising: fixed rings, movable rings and screw shafts, wherein each of the screw shafts is provided with the fixed rings and the movable rings in a staggered arrangement in a radial direction to form a cavity;
the two or more screw shafts arranged in the cavity side by side, and the fixed rings and the movable rings are in the form of an annular structure with two rings staggered and communicated or multiple rings staggered and communicated;
the separator further comprises a primary drive rod, a secondary drive rod, and a guide rod, wherein
the primary drive rod is connected to an independent drive motor, or is connected to the screw shafts via a transmission mechanism;
the primary drive rod is supported by two or more support devices, and one or more eccentric devices are provided on the primary drive rod;
each of the eccentric devices is connected to the secondary drive rod via a drive sheet;
the secondary drive rod is sleeved in the lower ends of the movable rings and connects all of the movable rings together to form one piece; the guide rod passes through the upper ends of the movable rings and connects all of the movable rings together to form one piece; and the secondary drive rod drives the lower ends of the movable rings to make a pendulum motion while the guide rod drives the movable rings to move up and down by means of a linear guide device; and
the transmission mechanism or the drive motor drives the primary drive rod to move, the eccentric devices on the primary drive rod drive the secondary drive rod to move, and the secondary drive rod drives all the movable rings to move.

### Claim 2 (depends on 1)
