A circular frame 3 is welded at one end of the top of the reactor body 1. A movable block 41 is movably penetrated inside the circular frame 3. The two sides of the movable block 41 are respectively fitted with two inner side walls of the circular frame 3. A driving component 5 for lifting the movable block 41 is arranged at the top of the circular frame 3. The scraper ring 42 is located at the inner top of the reactor body 1. The outer side wall of the scraper ring 42 is fitted with the inner side wall of the reactor body 1. The two ends of the connecting rod 43 are welded with the inner side wall of the scraper ring 42. A first motor 44 is fixedly installed in the middle of the top of the movable block 41. The power shaft of the first motor 44 rotates and penetrates the movable block 41. A rotating rod 45 is welded at the end of the power shaft of the first motor 44. The first motor 44 can provide rotation for the rotating rod 45 Driving force, the rotating rod 45 rotates and passes through the reactor body 1. A connecting column 46 is welded at the bottom end of the rotating rod 45. The connecting column 46 is welded to the connecting rod 43. The connecting column 46 can be used to connect the rotating rod 45 and the connecting rod 43. The top of the connecting column 46 conflicts with the inner top wall of the reactor body 1. In this way, when the material reacts in the reactor body 1, no gas will escape from the rotating point where the rotating rod 45 and the reactor body 1 rotate. The driving component 5 drives the movable block 41 to descend, and the movable block 41 drives the first motor 44 to descend. The power shaft of the first motor 44 drives the rotating rod 45 and the connecting column 46 to rotate. The connecting column 46 drives the scraper ring 42 to rotate through the connecting rod 43. The scraper ring 42 can scrape off the material attached to the inner wall of the reactor body 1 during the rotation and descent process.
[0017] Reference Figure 1 , Figure 2 and Figure 3 The reactor body 1 is composed of a reaction barrel 11 and a barrel cover 12. The barrel cover 12 is installed on the top of the reaction barrel 11. The outer surface of the top of the reaction barrel 11 is provided with a fixing component 2 for fixing the barrel cover 12, so that the barrel cover 12 will not easily lose contact with the reaction barrel 11. One end of the top of the barrel cover 12 is connected with a feed pipe 15, through which materials can be added to the reaction barrel 11. A sealing plug 16 is movably inserted at the inner top of the feed pipe 15, and the sealing plug 16 can play a role in blocking the feed pipe 15. The four corners of the bottom end of the reaction barrel 11 are welded with supporting legs 13, and the four supporting legs 13 can cooperate to support the reaction barrel 11. The middle part of the bottom end of the reaction barrel 11 is connected with a discharge pipe 14 provided with an automatic valve. Opening the valve of the discharge pipe 14 can discharge the material in the reaction barrel 11 through the discharge pipe 14.

The upper ring 21 is fixedly sleeved on the outer surface of the barrel cover 12, and the lower ring 22 is fixedly sleeved on the outer surface of the support leg 13. The upper ring 21 is located at the top of the lower ring 22, so that the lower ring 22 supports the upper ring 21. There are four bolts 23, and the four bolts 23 are all threaded through the upper ring 21 and the lower ring 22, so as to fix the barrel cover 12 and the reaction barrel 11.
[0019] Reference Figure 2 and Figure 4 The driving assembly 5 is composed of a second motor 51 and a threaded rod 52. The second motor 51 is fixedly installed in the middle of the top of the circular frame 3. The power shaft of the second motor 51 rotates and penetrates the circular frame 3.

One end of the threaded rod 52 is welded to the power shaft of the second motor 51, and the other end of the threaded rod 52 is rotatably inserted in the middle of the inner bottom wall of the circular frame 3. When the power shaft of the second motor 51 drives the threaded rod 52 to rotate, the threaded rod 52 can apply a spiral thrust to the movable block 41, so that the movable block 41 can descend inside the circular frame 3.
[0020] The implementation principle of a laboratory micro reactor in the embodiment of the present application is as follows: when in use, materials are added to the reaction barrel 11 through the feed pipe 15, and then the sealing plug 16 is inserted into the inside of the feed pipe 15, so that the materials react inside the reaction barrel 11. After the reaction is completed, the valve of the discharge pipe 14 is opened to discharge it. At this time, the second motor 51 and the first motor 44 are started, and the power shaft of the second motor 51 drives the threaded rod 52 to rotate. The threaded rod 52 can apply a spiral thrust to the movable block 41, so that the movable block 41 can descend inside the circular frame 3. At the same time, the power shaft of the first motor 44 drives the rotating rod 45 and the connecting column 46 to rotate, and the connecting column 46 drives the scraper ring 42 to rotate through the connecting rod 43.
