The motor 4 drives the support rod 5 and the connecting rod 6 to rotate, so that the treatment cylinder 7 rotates. Centrifugal force is generated by the rotation, so that water can be thrown out for separation. The treatment cylinder 7 is upwardly extruded by the water squeezer 8, so that the device can perform extrusion drainage. By combining centrifugal drainage and extrusion drainage, the separation effect of the device is good.

[0036] As Figures 2 to 4 , Figures 6 to 7As shown in the figure, the processing cylinder 7 includes a first telescopic column 701. On the side of the first telescopic column 701 away from the support rod 5, a first corrugated plate 702 is movably connected. At the top of the first corrugated plate 702, a connecting ring 703 is fixedly connected. On the side of the connecting ring 703 away from the support rod 5, a second telescopic column 709 is fixedly connected. On the side of the second telescopic column 709 close to the support rod 5, a second corrugated plate 707 is movably connected. At the middle part of the second telescopic column 709, a first extrusion plate 705 is fixedly connected at equal angles in a ring shape. At the middle part of the first extrusion plate 705, screening holes 708 are equidistantly arranged.

The positions of the first extrusion plate 705 and the second extrusion plate 706 are staggered from each other. By driving the support rod 5 and the connecting rod 6 to rotate through the motor 4, the processing cylinder 7 rotates. Through the centrifugal force generated by the rotation, moisture can be thrown out through the screening holes 708. Through the corrugated cylinder 704, the thrown-out water can be blocked. The water flows out through the drainage holes 710 and drains away along the guide plate 11. Through the first telescopic column 701, the first corrugated plate 702, the second corrugated plate 707, and the second telescopic column 709, they can all contract and become shorter. Through the second corrugated plate 707 and the second telescopic column 709, the first telescopic column 701 and the first corrugated plate 702 can be protected. Through the compression of the first extrusion plate 705 and the second extrusion plate 706, they can be bent towards the middle, so that the mud can be extruded, the moisture can be quickly extruded and discharged from the screening holes 708, enabling the device to perform centrifugal separation and extrusion separation, and making the separation effect of the device good.

[0037] As Figures 2 to 3 、 Figure 5As shown, the water squeezer 8 includes a first bevel gear 801. The outer side of the first bevel gear 801 is meshed with second bevel gears 802 at equal angles in a circular shape. The other side of the second bevel gear 802 is fixedly connected to a first transmission wheel 803. The middle of the first transmission wheel 803 is rotatably connected to a first support column 804. The outer side of the first transmission wheel 803 is movably clamped with a transmission belt 805. The other side of the transmission belt 805 is movably clamped with a second transmission wheel 806. The middle of the second transmission wheel 806 is fixedly connected to a rotating rod 807. The middle of the rotating rod 807 is rotatably connected to a second support column 808. The other side of the second support column 808 is fixedly connected to a wire winding wheel 809. A pulling rope 810 is wound around the outer side of the second support column 808. The top of the pulling rope 810 is fixedly connected to a rotating wheel 811. The middle of the rotating wheel 811 is rotatably connected to a limiting rod 812. The middle of the limiting rod 812 is rotatably connected to a third support column 813. The other side of the limiting rod 812 is rotatably connected to a movable wheel 814. The bottom of the first support column 804 is fixedly connected to the fixed frame 1. The bottom of the second support column 808 is fixedly connected to the fixed frame 1. The bottom of the third support column 813 is fixedly connected to the fixed frame 1. The limiting rod 812 is of an L-shaped structure. The movable wheel 814 is located at the lower end of the treatment cylinder 7 and does not contact the bottom side of the treatment cylinder 7. The outer side of the third support column 813 is fixedly connected to the bottom of the guiding plate 11. The outer side of the limiting rod 812 is movably clamped with the guiding plate 11. By driving the first bevel gear 801 to rotate through the support rod 5, the first bevel gear 801 drives the second bevel gear 802 and the first transmission wheel 803 to rotate. The first support column 804 drives the second transmission wheel 806 to rotate through the transmission belt 805. The second transmission wheel 806 drives the wire winding wheel 809 to rotate through the rotating rod 807, so that the wire winding wheel 809 rotates to wind up the pulling rope 810, so that the pulling rope 810 pulls the limiting rod 812 through the rotating wheel 811, so that the limiting rod 812 rotates outward along the third support column 813, so that the movable wheel 814 contacts the bottom of the treatment cylinder 7 and jacks up the treatment cylinder 7. The friction with the treatment cylinder 7 can be reduced through the movable wheel 814, which is convenient for the extrusion operation of the treatment cylinder 7.

[0038] As Figure 4 , Figure 8As shown, the slag discharger 9 includes a movable ring 901. The middle part of the movable ring 901 is annularly and equiangularly provided with slag discharge ports 902. A blocking plate 903 is movably clamped inside the slag discharge ports 902. A connecting block 904 is hinged to the other side of the blocking plate 903. A limiting block 905 is movably clamped to the bottom of the connecting block 904. The outer side of the movable ring 901 is movably connected to the bottoms of the first telescopic column 701 and the second telescopic column 709 respectively. The outer side of the connecting block 904 is movably clamped to the movable ring 901. The top side of the limiting block 905 abuts against the blocking plate 903. The other side of the limiting block 905 is rotatably connected to the first telescopic column 701 and the second telescopic column 709 respectively. The blocking plate 903 and the connecting block 904 are both made of hard metal. When draining water, the limiting block 905 abuts against the blocking plate 903, and the blocking plate 903 does not contact the limiting rod 812. The pressure of the slurry enables the movable ring 901 to rotate synchronously with the treatment cylinder 7. After the water is discharged, by rotating the limiting block 905, the limiting block 905 does not abut against the blocking plate 903, and the blocking plate 903 is rotated downward and folded. The blocking plate 903 is vertically downward, so that the slag discharge ports 902 are opened. The limiting rod 812 can block the blocking plate 903, so that the movable ring 901 does not rotate. By driving the scraper 10 to rotate through the first pressing plate 705 and the second pressing plate 706, the mud on the top of the movable ring 901 can be scraped to the slag discharge ports 902 and dropped and discharged. It is worth noting that since the blocking plate 903 is blocked by the second bevel gear 802, the slag discharge ports 902 are located on one side of the water squeezer 8, and the discharged slag will not cause pollution to the water squeezer 8 when it falls.

[0039] As Figure 2 、 Figure 4 shown, the support rod 5 is of a cross-shaped structure. Both the left and right sides of the support rod 5 are fixedly connected to the connecting ring 703. The bottom of the support rod 5 is fixedly connected to the first bevel gear 801. The guiding plate 11 is of an inverted funnel-shaped structure with a narrow upper part and a wide lower part. The guiding plate 11 is located at the outer end of the slag discharge ports 902. The bottom side of the scraper 10 is movably connected to the movable ring 901. The lower end of the feed inlet 3 is located between the first pressing plate 705 and the second pressing plate 706. The bottom of the sealing cover 2 is connected to the connecting ring 703 by a bearing. The left and right sides of the scraper 10 are fixedly connected to the first pressing plate 705 and the second pressing plate 706 respectively. The treatment cylinder 7 can be supported and limited by the support rod 5. The first bevel gear 801 can be supported and fixed by the support rod 5. The discharged water can be drained through the guiding plate 11. The slag can be scraped and discharged by the rotation of the scraper 10.

[0040] For the technical solution provided by the present invention, first, the operator adds the slurry between the first extrusion plate 705 and the second extrusion plate 706 through the feed port 3, drives the support rod 5 and the connecting rod 6 to rotate through the motor 4, so that the treatment cylinder 7 rotates, and generates centrifugal force through the rotation, so that the water can be thrown out through the screening holes 708. The corrugated cylinder 704 can block the thrown-out water, and the water flows out through the drain holes 710 and is discharged along the guiding plate 11. The support rod 5 drives the first bevel gear 801 to rotate, so that the winding wheel 809 rotates to wind up the pulling rope 810, so that the pulling rope 810 pulls the limiting rod 812 through the runner 811, so that the limiting rod 812 rotates outward along the third support column 813, so that the movable wheel 814 contacts the bottom of the treatment cylinder 7 and jacks up the treatment cylinder 7, so that the first telescopic column 701, the first corrugated plate 702, the second corrugated plate 707, and the second telescopic column 709 all contract and become shorter, so that the first extrusion plate 705 and the second extrusion plate 706 are bent, and the first extrusion plate 705 and the second extrusion plate 706 can perform extrusion, so that the water is discharged from the screening holes 708;

[0041] After the water is discharged, by rotating the limiting block 905, the limiting block 905 does not abut against the blocking plate 903, and the blocking plate 903 is rotated and folded downward, and the blocking plate 903 is vertically downward, so that the slag discharge port 902 is opened. The limiting rod 812 can block the blocking plate 903, so that the movable ring 901 does not rotate. The first extrusion plate 705 and the second extrusion plate 706 drive the scraper 10 to rotate, and can scrape the mud on the top of the movable ring 901 to the slag discharge port 902 and drop it for discharge, thus completing the operation.

In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion to the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
