A drainage groove 20 is provided on the lower side of the inner wall of the base 1. The outer wall of the rotating frame 11 is rotatably connected to the inner wall of the base 1. A slot 19 is provided on all four sides of the inner wall of the rotating frame 11. A locking block 18 is provided on the inner wall of the slot 19. The outer wall of the locking block 18 is slidably connected to the inner wall of the connecting frame 14. A pull rod 15 is slidably connected to the inner wall of the connecting frame 14.

[0030] Working principle: First, place the moist iron concentrate into the filter frame 12 and pull the pull rods 15 on both sides upward. The pull rods 15 drive the rotating rods 17 on both sides to rotate upward, and drive the locking blocks 18 on both sides to retract inward. The filter frame 12 and the connecting frame 14 are then inserted into the rotating frame 11. After installation, push the pull rods 15 downward, locking the locking blocks 18 on both sides into the locking slots 19. Insert the threaded rod 16 into the pull rod 15 and rotate it into the threaded groove to limit the pull rod 15. Then, the controller starts the hydraulic rod 3, the heating ring 4, and the motor 8 respectively. The hydraulic rod 3 drives the heating ring 4 and the pressure plate 5 to move downward. During the descent, the sliders 7 on the four sides of the pressure plate 5 are respectively... Insert the iron concentrate into the groove 13 and continuously press it downwards to apply pressure. Then, the heating ring 4 on the upper side of the pressure plate 5 generates heat and transfers the heat to the pressure plate 5, allowing the iron concentrate to absorb the heat and dry. Next, the motor 8 drives the gear 9 to rotate, which in turn drives the gear ring 10 to rotate, and drives the rotating frame 11, filter frame 12 and pressure plate 5 to rotate, thus drying the iron concentrate. The moisture and steam generated during processing will move downwards and be discharged downwards through the drainage groove 20. After processing, the controller causes the hydraulic rod 3 to retract, retracting the pressure plate 5 upwards, and the motor 8 to be turned off. By rotating the threaded rod 16 and pulling the pull rod 15 upwards, the filter frame 12 can be removed, and the processed iron concentrate can be collected.
