A sewage discharge area, a feed area and a silt discharge area are arranged in sequence in the cavity along the rotation direction of the rotating roller 2. The size of the material cavity is smaller than that of the sewage discharge area, the feed area and the silt discharge area. The sewage discharge area is arranged at the bottom of the inner cavity, and the feed area and the silt discharge area are arranged on both sides of the sewage discharge area respectively. A drainage port is arranged at the bottom of the shell 1 to communicate with the sewage discharge area, a feed port is arranged in the middle to communicate with the feed area, and a discharge port is arranged at the lower side to communicate with the silt discharge area; an extrusion device is also arranged on the shell 1 in the feed area to cooperate with the paddle 3 to realize the extrusion and drainage of sludge.

[0025] The extrusion device includes a pressing plate 5 whose size matches that of the paddle plate 3 and an elastic reset device that can drive the pressing plate 5 back to the working position when no external force is applied. An opening that is connected to the feeding area is provided on the shell 1 above the feeding port, and the opening extends along the rotation direction of the rotating roller 2. The opening matches the size of the pressing plate 5. One end of the pressing plate 5 is hinged below the opening, and the other end is a free end. The pressing plate 5 is connected to the outer wall of the shell 1 through an elastic reset device. In the working state, the pressing plate 5 is arranged in the feeding area along the radial direction of the rotating roller 2 under the action of the elastic reset device. At this time, the pressing plate 5 is in the working position. The pressing plate 5 divides the feeding area into a lower extrusion area and an upper lead-out area. The feeding port is arranged in the extrusion area. In the non-working state, the pressing plate 5 is placed in the opening to close the opening.

[0026] The elastic reset device includes a plurality of telescopic arc rods 6 and a spring 7 sleeved on the outside of the telescopic arc rods 6. The pressure plate 5 is T-shaped and consists of a long plate and a short plate. The long plate of the pressure plate 5 matches the size of the dial plate 3. One end of the short plate of the pressure plate 5 is hinged to the outside of the shell 1 and below the opening. The other end of the short plate is fixedly connected to one end of the telescopic arc rod 6 on the outside. The other end of the telescopic arc rod 6 is fixed to the outside of the shell 1 and below the hinge of the short plate. One end of the spring 7 is fixedly connected to the outer wall of the shell 1, and the other end is fixedly connected to the short plate of the pressure plate 5.

[0027] like Figure 2 As shown, when working, the sludge first enters the feeding area from the feeding port, the transmission motor 18 drives the rotating roller 2 to rotate, and the rotating roller 2 drives the paddle 3 to rotate counterclockwise, thereby driving the sludge in the feeding area to rotate, and the paddle 3 drives the sludge to contact the pressing plate 5. As the paddle 3 continues to rotate, the paddle 3 and the pressing plate 5 squeeze the sludge, squeeze out the muddy water in the sludge, and the muddy water flows into the sewage discharge area from the inner filter screen 4 on the paddle 3, and then is discharged from the drain port. As the paddle 3 continues to rotate, the paddle 3 pushes the pressing plate 5 to overcome the elastic force of the spring 7 sleeved outside the telescopic arc rod 6, so that the pressing plate 5 rotates around its hinge point into the opening to close the opening. At this time, the pressing plate 5 no longer hinders the rotation of the paddle plate 3. The paddle plate 3 drives the sludge discharged from the water to continue to rotate to the silt discharge area, and the sludge is discharged from the discharge port. At the same time, the pressing plate 5 loses the external force, and the pressing plate 5 is reset under the action of the telescopic arc rod 6 and the spring 7, so that the pressing plate 5 rotates to the working position of the shell 1, and the cycle continues to achieve continuous collection and squeezing of the sludge.

[0028] Furthermore, a lower filter screen 9 is detachably installed in the drain outlet of the shell 1, a bottom cylinder 8 is threadedly connected to the drain outlet, a water outlet pipe 12 is installed on the side of the bottom cylinder 8, a bottom cover 13 is threadedly installed on the bottom of the bottom cylinder 8, a discharge cylinder 10 is installed on the discharge port of the shell 1, a sludge pump 11 is fixed to the outside of the shell 1 by bolts, the outlet of the sludge pump 11 is connected to the feed port of the shell 1 through a pipeline, and the sludge pump 11 pumps the sludge into the shell 1.

[0029] A vibration motor 14 is also fixed to the shell 1, and the vibration motor 14 drives the shell 1 to vibrate, thereby vibrating off the silt attached to the inner wall of the shell 1. A plurality of inspection ports connected to the inner cavity are also opened on one side of the shell 1. The shell 1 is hinged with a sealing door 15 on the inspection port, and the shell 1 is convenient for cleaning through the inspection port. The shell 1 is fixed as a whole on the frame 16, and a plurality of ground wheels 17 as running wheels are fixed to the bottom of the frame 16, which facilitate the movement of the device.

[0030] The working principle of this embodiment is as follows: when in use, first, the sludge is pumped into the housing 1 under the action of the sludge pump 11, and then, the rotating roller 2 is rotated under the drive of the transmission motor 18, thereby driving the paddle 3 to rotate counterclockwise, and then driving the sludge to rotate, so that the sludge is squeezed with the pressure plate 5, thereby squeezing out the muddy water in the sludge, and the squeezed muddy water falls into the bottom cylinder 8 through the inner filter screen 4, and then discharged from the outlet pipe 12. When the extrusion force of the paddle 3 is greater than the elastic force of the spring 7, the pressure plate 5 is rotated to the outside of the housing 1 under the extrusion of the paddle 3, thereby facilitating the passage of the paddle 3. After the paddle 3 passes, the telescopic arc rod 6 is reset under the elastic action of the spring 7, thereby rotating the pressure plate 5 into the housing 1, and then facilitating the continued squeezing of the sludge. When the sludge rotates to the discharge barrel 10, it is discharged from the discharge barrel 10, and then the housing 1 is vibrated under the drive of the vibration motor 14, thereby vibrating the sludge attached to the inner wall of the housing 1 so that the sludge can be fully discharged.
