The side plates 3 are fixedly mounted with second mounting brackets 9, and a plurality of threaded mounting holes are provided on the second mounting brackets 9. The separation mechanism includes two electromagnets 10, and mounting grooves 11 are provided on the opposite sides of the two pushers 8. The electromagnets 10 are respectively arranged in the mounting grooves 11, and the electromagnets 10 are fixedly mounted on the pushers 8. The bottom of the inner cavity 6 is provided with two guide grooves 12 arranged at intervals, and sliders 13 are slidably arranged in the guide grooves 12. The upper ends of the sliders 13 are fixedly connected to the pushers 8. A round rod 14 is arranged in the guide groove 12, and the round rod 14 passes through the slider 13 and the ends are fixedly connected to the base 1.

[0024] Therein, movable blocks 15 are arranged at both ends of the interval between the two strip-shaped ceramic plates 4, a bracket 16 is fixedly installed on the second mounting frame 9, and a plurality of guide rods 17 are fixedly installed between the two brackets 16, and the guide rods 17 respectively penetrate the movable blocks 15.

[0025] The working principle of the utility model is as follows: the base 1 is installed in the pressing section or dewatering section of the paper machine. In these areas, after the paper is initially formed, the first mounting frame 2 dehydrates the paper, and the excess water is removed through the pressing or dewatering steps to achieve the desired dryness and quality. The liquid passes through the first mounting frame 2, and the first mounting frame 2 adopts a porous or microporous structure. These pores allow the liquid to pass through, but can retain solid particles. When the liquid containing solid particles passes through the ceramic dehydration element, the solid particles are retained on the surface or inside of the element, and the liquid flows out through the pores, thereby achieving solid-liquid separation.

[0026] The separated liquid enters the inner cavity 6, and is guided to the drain port 7 by the inclined surface on the side of the push member 8.

Specifically, the electromagnet 10 is energized, and the electromagnets 10 on both sides repel each other, and the push member 8 moves along the direction of the round rod 14, thereby realizing the opposite movement of the push members 8 on both sides. The liquid retained between the strip ceramic plates 4 is moved by driving the connecting frame 18, and the connecting frame 18 drives the multiple movable blocks 15 to move. The movable blocks 15 can push the liquid retained between the strip ceramic plates 4 and discharge it from the port of the gap, thereby reducing the liquid retained between the strip ceramic plates 4. Since the liquid is effectively discharged, the humidity of the paper can be better controlled, thereby ensuring the uniformity and quality of the paper. This helps to improve the smoothness, glossiness and mechanical strength of the paper, making the paper more in line with production requirements.
