[0027] Working principle: when using the nucleation device, the raw materials for preparing lithium iron phosphate by the high-temperature fixing method are pretreated and placed inside the preparation furnace 1. After being heated to a certain degree, the raw materials are heated inside the preparation furnace 1 for a period of time to react into lithium iron phosphate. When using the gas outlet device 7, the fan 703 is slid to the inner wall of the end of the first connecting tube 701 away from the discharge pipe 3, and then the ring 721 is manually controlled to rotate on the inner wall of the positioning groove 720, so that the ring 721 can be well threaded on the surface of the end of the first connecting tube 701 away from the discharge pipe 3, so that the fan 703 can be well set inside the first connecting tube 701, and the reverse operation can remove the fan 703, which is convenient for the fan. 703 is maintained, the baffle plate 708 is manually controlled to slide out of the connection box 707, at this time the sliding block 711 slides to the bottom of the slide slot 710, and then the L-shaped plate 716 is controlled to be inserted into the inside of the slide slot 710, and the L-shaped plate 716 is pulled toward the direction close to the positioning plate 714 by the second spring 717, and then the L-shaped plate 716 is well restricted to the top of the sliding plate 709, so that the baffle plate 708 can be kept away from the inside of the connection box 707, so that the wind blown by the fan 703 can pass through the first connecting pipe 701 well, and then the extension pipe 724 is manually slid to the inner wall of the connecting ring 725, and then the moving ring 727 is manually controlled to slide on the inner wall of the limiting groove 728, so that the moving ring 727 is close to the extension pipe 724, and then the positioning bar After passing through the limiting groove 728, 729 is arranged on the side of the locking ring 732 close to the extension tube 724, and the locking strip 729 is pulled in the direction close to the movable ring 727 by the third spring 731, so that the locking strip 729 can be well limited to one side of the locking ring 732, and then the extension tube 724 can be well arranged at the end of the second connecting tube 702 away from the discharge pipe 3, so that the length of the second connecting tube 702 can be lengthened to a certain extent, which makes it easier to pass the hot air to the outside, and blow air into the inside of the first connecting tube 701 through the fan 703, and then the hot air generated in the preparation furnace 1 can be blown out of the outside through the second connecting tube 702, and the function of the first filter 704 is to prevent lithium iron phosphate from entering the inside of the first connecting tube 701 The function of the second filter 705 is to prevent lithium iron phosphate from entering the second connecting pipe 702. When the hot air passes through the second connecting pipe 702, because the heat dissipation ring 706 is arranged on the surface of the second connecting pipe 702 arranged on the outdoor part, the temperature of the hot air can be reduced to a certain extent through the heat dissipation ring 706, which can avoid a significant increase in the temperature of the indoor environment to a certain extent. When the air outlet device 7 is not used, the baffle 708 is slid into the inside of the connecting box 707, and then the positioning plate 714 is manually controlled to slide on the inner wall of the connecting groove 713, and then the end of the positioning plate 714 away from the connecting groove 713 is slid into the inside of the rectangular groove 712, and the positioning plate 714 is pulled toward the direction close to the connecting box 707 by the first spring 715.In this way, the baffle plate 708 can be well restricted inside the connecting box 707, which can prevent the hot air from being away from the end of the first connecting tube 701 away from the discharge tube 3 and away from the preparation furnace 1 to a certain extent. When using the connecting device 8, the fixing ring 804 is slid into the inside of the circular groove 803, so that the first connecting tube 801 can be set on the top of the second connecting tube 802. In the process of sliding the first connecting tube 801 into the cylinder 805, the semicircular plate 808 slides inside the semicircular groove 809. After the first connecting tube 801 completely slides into the cylinder 805, the rotating ring 807 is manually controlled to rotate inside the positioning groove 806, and then the semicircular plate 808 is slid into the inside of the fixing groove 810. In this way, the first connecting tube 801 can be well restricted inside the cylinder 805, thereby well restricting the first connecting tube 801. The connecting tube 801 and the second connecting tube 802 are connected together, and then the fixing rod 811 is passed through the rotating ring 807 and then through the rectangular plate 813, and then the fixing rod 811 is pulled toward the rotating ring 807 by the fourth spring 812, so that the fixing rod 811 is well restricted inside the rectangular plate 813, so that the rotating ring 807 can be well fixed inside the positioning groove 806, and then the insulation belt 814 is wrapped around the connection between the first connecting tube 801 and the second connecting tube 802, so that a certain sealing and insulation effect can be achieved, and the reverse operation can disassemble the preparation furnace 1 into the first connecting tube 801 and the second connecting tube 802, so that it is convenient to clean the lithium iron phosphate or other substances that may remain inside the preparation furnace 1, so as to avoid such substances from affecting subsequent experiments to a certain extent.
