[0023] A vertical row of stirring rods 12 is fixed on the outer wall of the filter cartridge 11 .

[0024] The extraction tank 1 is provided with a cleaning brush 9, the bristles of which are matched with the outer wall of the filter cartridge 11, and the cleaning brush 9 is connected with a horizontal telescopic rod 10, which is an electric push rod or a hydraulic rod, and the fixed end of the horizontal telescopic rod 10 is fixed on the outer wall of the extraction tank 1, and the motor is a forward and reverse motor 17. During extraction, the horizontal telescopic rod 10 is retracted, and the cleaning brush 9 is away from the filter cartridge 11, which does not affect the extraction of the filter cartridge 11. After the extraction is completed, the horizontal telescopic rod 10 is extended, and the cleaning brush 9 contacts the outer wall of the filter cartridge 11, and the filter cartridge 11 rotates forward and reverse periodically, and the cleaning brush 9 cleans the filter cartridge 11.

[0025] The filter cartridge 11 is equipped with a material pressing assembly, which includes a vertical telescopic rod 4 and a material pressing plate. The material pressing plate is circular and includes a fixed plate 5 and a movable plate 7. The movable plate 7 is hinged to the fixed plate 5. The circular arc corresponding to the movable plate 7 is an inferior arc. The top of the fixed plate 5 is fixedly connected to the telescopic end of the vertical telescopic rod 4. The lower surface of the fixed plate 5 is fixedly connected with a vertical connecting rod. The lower end of the connecting rod is hinged with a push rod 6. The push rod 6 is an electric push rod. The other end of the push rod 6 is hinged to the lower surface of the movable plate 7.

After the extraction is completed, the drain port 15 is opened to discharge the extract. The filter cartridge rotates to perform centrifugal filtration in the filter cartridge. Finally, the push rod is extended to make the movable plate and the fixed plate form a circular pressing plate. The pressing plate is driven downward by the vertical telescopic rod 4 to press down the material in the filter cartridge 11, so that the liquid in the material can be pressed out more fully. After the extract is discharged, the slag discharge pipe 13 is opened to discharge the slag. Finally, the extraction tank and the filter are cleaned to avoid clogging of the filter holes and affecting the next use. Specifically, the horizontal telescopic rod 10 is extended, the cleaning brush 9 contacts the outer wall of the filter cartridge 11, the filter cartridge 11 rotates, and the cleaning brush 9 cleans the outer wall of the filter cartridge 11. The vertical telescopic rod drives the pressing plate to reciprocate up and down in the filter cartridge to clean the inner wall of the filter cartridge. Cleaning liquid can also be introduced into the extraction tank to make it clean more thoroughly. The waste liquid after cleaning can be discharged through the slag discharge port or the liquid discharge port.
