The third hanging plate 36 is connected to a fourth motor 37 and a second hanging rod 42. The fourth motor 37 is connected to a threaded rod 38, and the threaded rod 38 is threadedly connected to a fourth hanging plate 39. The fourth hanging plate 39 is connected to a push-pull rod 40, and the push-pull rod 40 is connected to a push-pull plate 41. The second hanging rod 42 is connected to a fifth hanging plate 43.

[0027] When the device for realizing magnetic separation and cleaning is in use, the solution required for the experiment is injected into the liquid filling tank 29 through the solution adding pipe 30. The touch display screen 50 is operated to select the automatic mode. Then, the second motor 11 will first turn the rod 15 to the position of the protective cap 8, and the electromagnet 17 is started to adsorb the protective cap 8. After the first telescopic rod 14 lifts the protective cap 8 away from the magnetic separation disk 5, the second motor 11 turns the protective cap 8 away from the magnetic separation disk 5. The second telescopic rod 23 lowers the bottom of the liquid injection pipe 28 into the reaction cup 7. The pump 31 pumps the solution in the liquid filling tank 29 into the reaction cup 7. Then, through the second motor 11 and the first telescopic rod 14, the protective cap 8 covers the magnetic separation disk 5. The electromagnet 17 is turned off and the rod 15 is turned away from the protective cap 8. The first motor 2 drives the reaction cup 7 to rotate.

The third motor 21 rotates to make the liquid injection structure and the liquid suction structure change positions. After the position change, the fourth motor 37 pushes the push-pull plate 41 into the liquid suction pipe 45 to a sufficient depth. The third telescopic rod 35 pushes the bottom of the liquid suction pipe 45 into the solution in the reaction cup 7.

The third telescopic rod 35 then lifts the liquid suction pipe 45 to make it leave the reaction cup 7. The third motor 21 rotates again to make the liquid injection structure and the liquid suction structure change positions. After the position change again, the third telescopic rod 35 pushes the bottom of the liquid suction pipe 45 into the test tube 47. The fourth motor 37 rotates to make the push-pull plate 41 move downward to make the solution enter the test tube 47. The third telescopic rod 35 then pulls the liquid suction pipe 45 back to its original position. After that, cleaning liquid is poured into the liquid filling tank 29 and the above operations are repeated.

[0028] This device is equipped with a magnetic separation structure, a liquid injection structure, and a liquid absorption structure. The manual mode and the automatic mode can be set through the touch display screen 50. In the automatic mode, the complete experimental process can be automatically carried out according to the program throughout the process. There are multiple liquid storage tanks 29, reaction cups 7, and test tubes 47 with the same quantity, and different experiments can be carried out simultaneously. The protective cap 8 is made of a thin and light iron structure and can be adsorbed by the electromagnet 17, which is convenient to remove. Moreover, the elastic rubber inside the side walls around it can effectively protect the magnetic separation disc 5. The splash-proof cover 10 can prevent the solution in the reaction cup 7 from splashing out of the reaction cup 7 during the experiment. The magnetic separation disc 5, the reaction cup 7, the test tube box 46, and the test tube 47 are all transparent circular structures, which are convenient for observing the experimental process and results.
