The end of the screen cylinder 40 facing the drive motor 20 is located in the third escape opening 144.
Referring to fig. 8 and 9, the diameter of the extrusion shaft 30 gradually decreases from the end close to the driving motor 20 to the end away from the driving motor 20, and the vertical distance from the end of the spiral blade to the axial center of the extrusion shaft 30 is kept consistent, so that the vertical distance from the outer edge of the spiral blade to the circumferential side of the extrusion shaft 30 gradually increases from the end close to the driving motor 20 to the end away from the driving motor 20. Because the material moves from the end far away from the driving motor 20 to the end close to the driving motor 20, the space where the material is located is smaller and smaller, so that the material is extruded, slurry is extruded, and slag is formed.
The end of the screw blade facing the drive motor 20 is located close to the slag chute 14 in the filtrate portion of the extrusion.
The extruding shaft 30 is provided with a convex ring 33 protruding from the circumferential side surface of the spiral blade facing the outer side of the end of the driving motor 20, and a pulling piece 34 protruding from the convex ring 33 facing one side of the driving motor 20 and opposite to the end of the spiral blade in the radial direction.

The inner side surface of the screen drum 40 close to the middle opening is provided with a pressure sensor, and the pressure sensor is connected with a pressure gauge and a controller. The controller is connected to the pressure maintaining cylinder 81.
When the slag is extruded from the first gap, the slag contacts the pressure maintaining assembly 80 and pushes the pressure maintaining assembly 80 against the driving motor 20, so that an opening is formed between the pressurizing surface 84 of the pressure maintaining assembly 80 and the slag separating plate 14, and the opening is enlarged.
The pressurizing surface 84 is provided with a scraping plate 82 in an inclined and protruding manner, and the scraping plate 82 is used for scattering and scraping slag close to the pressurizing surface 84, so that the slag enters the slag discharging part and falls off through the discharging unit 60.
The slag material passing over the convex ring 33 rotates along with the extrusion shaft 30 due to the large friction force between the slag material and the convex ring 33 or the extrusion shaft 30, so that the slag material cannot move forward continuously, the slag material is accumulated, and the extrusion shaft 30 is easily locked. Since the pressure maintaining assembly 80 and the scraper plate 82 are not rotated, the slag rotating along with the extrusion shaft 30 is scattered by the scraper plate 82.
The controller controls the pressure maintaining cylinder 81 to operate, so that the pressure maintaining cylinder 81 drives the pressure maintaining assembly 80 to move towards the screen cylinder 40, so that the pressure among the pressure maintaining assembly 80, the screen cylinder 40 and the extrusion shaft 30 is maintained within a predetermined pressure value range.
