A spiral blade 713 is installed inside the drain barrel 701, and the spiral blade 713 facilitates the discharge of the sludge separated in the drain barrel 701, and the driving motor 404 drives the screw When the dragon 405 is working, the second pulley 710 on the output shaft of the drive motor 404 rotates accordingly. The second pulley 710 drives the first pulley 708 to rotate through the belt 709, and then drives the first rotating shaft 707 and the first gear 706 to rotate. The first gear 706 engages with the toothed disc 705 to drive the drain barrel 701 to rotate in the cylinder 2. The sludge discharged from the guide pipe 402 enters the drain barrel 701 and is preliminarily separated from the sewage. The sewage in the sludge falls to the bottom of the cylinder 2 through the drain barrel 701. The sludge is discharged from the drain barrel 701 and the spiral blade 713.

The sludge discharged from the drain barrel 701 falls into the guide cover 9 and enters the interior of the sleeve 801 through the feed port 803. The gear disc 705 rotates while driving the second gear 711 to rotate. After the second gear 711 rotates, it drives the second rotating shaft 712 to rotate. The cam 805 on the second rotating shaft 712 rotates accordingly. After the cam 805 rotates, it squeezes the movable plate 806. The movable plate 806 drives the guide rod 807 to move. The guide rod 807 drives the extrusion block 810 to slide inside the sleeve 801 toward the filter screen 802. In this process, the extrusion block 810 will block the feed port 803 so that the sludge no longer enters the interior of the sleeve 801. At the same time, the blocking block 811 is connected to the Under the action of rod 809, it slides along the bearing groove 812 toward the filter screen 802 until the end of the blocking block 811 contacts the filter screen 802, and the blocking block 811 no longer moves.

The moisture inside the sludge can pass through the filter screen 802 and be discharged to the outside of the sleeve 801, and the sludge is intercepted by the filter screen 802 inside the sleeve 801. As the movable plate 806 continues to move, the connecting rod 809 also moves synchronously, and the connecting rod 809 drives the slider 817 to slide along the support rod 815. At this time, the second spring 816 is squeezed, and the blocking block 811 no longer moves.When the cam 805 no longer squeezes the movable plate 806, the movable plate 806 moves in the opposite direction under the action of the first spring 808. The movable plate drives the blocking block 811 to move in the opposite direction through the connecting rod 809 until the blocking block 811 and the squeezing block 810 move to their initial positions. At this time, the feed port 803 and the discharge port 804 are no longer blocked. After the squeezing is completed, the sludge forms a round cake and falls through the discharge port 804 into the drying component. This process is repeated to continuously squeeze the sludge.
