DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] As shown in FIG. 1 to FIG. 5, a multi-shaft laminated spiral solid-liquid separator with a pendulum motion includes fixed rings 1, movable rings 2, and two screw shafts 3 arranged side by side, where each of the screw shafts 3 is provided with the fixed rings 1 and the movable rings 2 in a staggered arrangement in a radial direction to form a cavity.

[0030] The separator further includes a primary drive rod 4, a secondary drive rod 5, and a guide rod 10.

[0031] The screw shafts 3 are connected to the primary drive rod 4 via a transmission mechanism 6, where the transmission mechanism 6 may use gear transmission, sprocket transmission, or belt transmission. However, the primary drive rod 4 is not necessarily driven by the screw shafts 3, and may also be connected to and driven by an independent drive motor (not shown in the figure).

[0032] The primary drive rod 4 is disposed above the cavity and supported by two support plates 7. Four eccentric bearings 8 are provided on the primary drive rod 4 at intervals.

[0033] Each of the eccentric bearings 8 is connected to the secondary drive rod 5 via a drive sheet 9. The secondary drive rod 5 is sleeved in the lower ends of the movable rings 2 and connects all of the movable rings 2 together to form one piece. The drive sheets 9 and their corresponding movable rings 2 are integrally connected. The movable ring 2 provided with the drive sheet 9 is referred to as a transmission movable ring 21.

[0034] The support plate 7 is provided with a guide device 71, a giving-way hole 72, pillar holes 73 connected to the fixed ring 1, a cavity hole 74 for accommodating a solid-liquid separation part, and a fixing hole 75 for fixing the primary drive rod 4.

[0035] The guide rod 10 is sleeved in the upper ends of the movable rings 2 and connects all of the movable rings 2 together to form one piece. The guide rod 10 passes through the guide device 71 on the support plate 7. The guide device 71 is a linear hole, and is used to give way to the guide rod 10 to make a linear motion. The secondary drive rod 5 passes through the giving-way hole 72 on the support plate 7, and the giving-way hole 72 is used to give way to the secondary drive rod 5 to make a pendulum motion. The fixing hole 75 is used for fixing the primary drive rod 4.

[0036] The screw shafts 3 drive the primary drive rod 4 to move via the transmission mechanism 6, the eccentric bearings 8 on the primary drive rod 4 drive the transmission movable rings 21 to move, and the transmission movable rings 21 drive all the movable rings 2 to move via the secondary drive rod 5. Under the effect of the eccentric bearings 8 and the guide devices 71, the guide rod 10 drives the upper ends of all the movable rings 2 to make a linear motion. Under the effect of the eccentric bearings 8 and the giving-way holes 72, the secondary drive rod 5 drives the lower ends of all the movable rings 21 to make a pendulum motion.

[0037] As shown in FIG. 6 and FIG. 7, the two screw shafts 3 are driven by a gear transmission mechanism 6 to operate in the same direction. The gear transmission mechanism 6 includes a driving screw shaft gear 61, a driven screw shaft gear 62, a transmission gear 63, and a primary drive rod gear 64. The transmission gear 63 engages with the driving screw shaft gear 61, the driven screw shaft gear 62, and the primary drive rod gear 64.

[0038] As shown in FIG. 8 and FIG. 9, the two screw shafts 3 are driven by a gear transmission mechanism 6 to operate in reverse directions. The gear transmission mechanism 6 includes a driving screw shaft gear 61, a driven screw shaft gear 62, a transmission gear 63, and a primary drive rod gear 64. The driving screw shaft gear 61 engages with the transmission gear 63 and the driven screw shaft gear 62; and the transmission gear 63 further engages with the primary drive rod gear 64.

[0039] The above merely describes preferred embodiments of the present application, but is not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present application shall fall within the protection scope of the present invention.
