The two first brackets 18 support the working box 13, and the two second brackets 19 support the movable groove 25. Example

[0023] like Figure 1-Figure 4 As shown, a heating coil 22 is installed and connected to the surface side of the crucible 7, the surface wall of the heating coil 22 is electrically connected to a battery 21, the bottom wall of the battery 21 is installed and connected to a third bracket 20, one side of the surface of the crucible 7 is fastened to a fourth bracket 24, one side of the top wall of the fourth bracket 24 is installed and connected to a flamethrower 15, and one side of the top wall of the fourth bracket 24 is installed and connected to an air gun 14, one side of the surface of the flamethrower 15 is connected to a fuel cartridge 17, one side of the surface of the air gun 14 is connected to a combustion-supporting combustion cartridge 16, and one side of the top wall of the crucible 7 is fastened to a discharge port 23.

[0024] In this embodiment, the user turns on the battery 21 installed on the third bracket 20, so that the heating coil 22 starts to heat, and the N-methylpyrrolidone inside the crucible 7 is heated. Then, the fuel cylinder 17 is opened and the flamethrower 15 installed on the fourth bracket 24 is turned on to heat the inside of the crucible 7. Since the heating speed of the heating coil 22 is not enough, the flamethrower 15 is used to supplement the heat to avoid uneven heating of the N-methylpyrrolidone block, which leads to reduced quality of the produced N-methylpyrrolidone. At the same time, the combustion-supporting cylinder 16 is turned on, the air gun 14 is started, and the heat of the flamethrower 15 is supplemented to further increase the heat when heating the N-methylpyrrolidone, so as to avoid uneven heating and insufficient heating of the N-methylpyrrolidone.

[0025] During operation, an extraction device for preparing N-methylpyrrolidone is connected to a power source by a user, and the cylinder 6 inside the clamping box 2 is started. The cylinder 6 works to drive the two connecting plates 5 to move toward each other. A clamping plate 9 is tightly connected to one side of the surface wall of the connecting plate 5. The movement of the connecting plate 5 drives the clamping plate 9 to move, thereby avoiding the influence of the high-temperature crucible 7 on the health of the user. Therefore, the movement of the connecting plate 5 drives the movement of the connecting column 11, and the movement of the connecting column 11 drives the movement of the rack 4, so that the rack 4 moves on the gear 3, which has a limiting effect on the connecting plate 5, and drives the two racks 4 to move as synchronously as possible.

Finally, the user turns on the battery 21 installed on the third bracket 20, so that the heating coil 22 starts to heat, and the N-methylpyrrolidone inside the crucible 7 is heated. Then, by opening the fuel cartridge 17 and the flamethrower 15 installed on the fourth bracket 24, the inside of the crucible 7 is heated. Since the heating coil 22 does not heat up quickly enough, the flamethrower 15 is used to supplement the heat, and at the same time, the combustion-supporting cartridge 16 is turned on, and the air gun 14 is started to supplement the heat of the flamethrower 15.
