[0030] The power assembly comprises a guide rail 6 fixedly arranged in the preparation cylinder 1. The guide rail 6 is annular, and the rotating shaft 9 is coaxially arranged through the guide rail 6. The guide rail 6 is provided with a wave-shaped annular guide groove 601 in the circumferential direction, and the wave-shaped annular guide groove 601 comprises two lower protrusions and two upper recesses in the embodiment. The guide groove 601 is downwardly opened, and each connecting piece is in limiting sliding cooperation with the guide groove 601.

Control valves are arranged in the first feeding port 2, the second feeding port 3 and the discharging port 5, and the control valves are prior art, and the specific use process is not described herein.

[0035] After the chemical reagents enter the preparation cylinder 1, the chemical reagents in the preparation cylinder 1 are heated by the heating rod 10 to reach a suitable reaction temperature.

[0036] At the same time, the motor 4 is started, the output shaft of the motor 4 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the heating rod 10 to revolve around the rotating shaft 9 through the hinge seat 12. The heating rod 10 drives the stirring rod 8 to revolve around the rotating shaft 9, and at the same time, the stirring rod 8 drives the sliding block 7 to revolve around the rotating shaft 9, and the sliding block 7 drives the limiting block to slide in the guide groove 601.

[0037] In the process, the top groove bottom of the guide groove 601 drives the limiting block to reciprocate up and down, and the limiting block drives the sliding block 7 to reciprocate up and down. The sliding block 7 drives the stirring rod 8 to reciprocate up and down, and the stirring rod 8 drives the heating rod 10 to reciprocate in a fan shape in the vertical direction. So that the heating rod 10 contacts more chemical reagents, and the temperature rises faster.

[0038] In the process of reciprocating rotation of the heating rod 10, the stirring rod 8 is driven to reciprocate horizontally along the radial direction of the rotating shaft 9. At the same time, the first spring 11 is repeatedly compressed by the stirring rod 8.

[0043] The working principle of the second embodiment is different from that of the first embodiment in that when the output shaft of the motor 4 rotates, the connecting shaft 13 is driven to rotate, and the connecting shaft 13 drives the push block 14 to rotate the rotating shaft 9. In the process of rotating the rotating shaft 9, the lower transmission plate 17 is driven to rotate. The lower transmission plate 17 drives the connected wave plate to rotate, and at this time, the wave plate on the upper transmission plate 16 pushes the wave plate on the lower transmission plate 17 to move up and down reciprocatingly. The lower transmission plate 17 moves up and down reciprocatingly with the connected wave plate, and the lower transmission plate 17 drives the rotating shaft 9 to slide up and down reciprocatingly. The rotating shaft 9 drives the push block 14 to repeatedly compress the second spring 15.

[0044] In the process of rotating the rotating shaft 9, the heating rod 10 is driven to revolve around the rotating shaft 9. The heating rod 10 drives the stirring rod 8 to revolve around the rotating shaft 9, and the stirring rod 8 drives the sliding block 7 to revolve around the rotating shaft 9. The sliding block 7 drives the limiting block to slide along the slide 101.

[0045] In the process of reciprocatingly sliding the rotating shaft 9 up and down, the heating rod 10 is driven to reciprocatingly rotate in a fan shape in the vertical direction. At this time, the heating rod 10 drives the stirring rod 8 to reciprocatingly move along the radial direction of the rotating shaft 9, and the stirring rod 8 repeatedly compresses the first spring 11.
