Subsequently, after the fan-shaped disk 613 swings to the left to the maximum stroke, the rotating rod 69 slides to the upper part of the arc groove 614, and then the rotating rod 69 continues to drive the cross guide column 611 to reverse and drive the fan-shaped disk 613 to swing to the right, and the stirring plate 618 also moves to the right to stir the mineral powder and sulfuric acid again. Similarly, after the fan-shaped disk 613 swings to the right to the maximum stroke, the rotating rod 69 slides to the lower part of the arc groove 614, and this is repeated to continuously stir the mineral powder and sulfuric acid. After all the original ore reactions are completed, the motor 44 is turned off, the second rotating shaft 43 stops driving the third rotating shaft 63 to reverse through the transmission assembly 64, and the stirring plate 618 also stops moving left and right. In this way, the mineral powder and sulfuric acid can be conveniently stirred.

[0047] When the mineral powder and sulfuric acid are mixed and reacted, the monitor 73 detects the pH value of the mixed liquid through the probe 74, and then people can record the pH value displayed on the monitor 73, and then people can pull the pull rod 77 to move forward, and the pull rod 77 moves forward to drive the sliding rod 76 to move forward, and the reset spring 78 is compressed, and then the pull rod 77 is pulled upward to the groove under the positioning slot plate 79, and the pull rod 77 moves upward to drive the sliding rod 76 to move upward, and the sliding rod 76 moves upward to drive the mounting block 75 to move upward, and the mounting block 75 moves upward to drive the sliding frame 72 to move upward, and the sliding frame 72 moves upward to drive the monitor 73 to move upward, and the monitor 73 moves upward to drive the probe 74 upward, and then release the pull rod 77.
