The adjustment component comprises an electric push rod 4, the electric push rod 4 is fixedly connected to the top of the still 1, and the mounting frame 5 is fixedly connected to the bottom end of the electric push rod 4. The mounting frame 5 can be driven to move up and down by the electric push rod 4, so as to adjust the position of the mounting frame 5. The middle part of the mounting frame 5 is rotatably connected with a sleeve rod 6, and the sleeve rod 6 and the rotating rod 3 are connected by a clamping assembly. When the rotating rod 3 rotates, the sleeve rod 6 can be synchronously rotated under the action of the clamping assembly.

A groove matching the limit block 9 is provided in the middle part of the sleeve rod 6, and the sleeve rod 6 is slidably connected to the outer periphery of the rotating rod 3 through the groove and the limit block 9. The rotating rod 3 and the sleeve rod 6 are connected by the limit block 9, and the sleeve rod 6 slides on the outer periphery of the limit block 9, which can cooperate with the mounting frame 5, and the position of the sleeve rod 6 can be adjusted while ensuring that the sleeve rod 6 can rotate.

[0031] Reference Figure 2-Figure 3 , multiple stirring rods 7 are fixedly connected to the outer periphery of the sleeve rod 6, and a stirring plate 8 is fixedly connected to the end of the stirring rod 7 away from the sleeve rod 6, and the stirring plate 8 is placed obliquely. The sleeve rod 6 can rotate to make the stirring rod 7 rotate to stir the oil, thereby improving the heating efficiency. At the same time, the inclined stirring plate 8 can further improve the stirring effect. A cavity 18 is opened on the inner wall of the still 1, and multiple heating pipes 19 are fixedly connected to the middle of the cavity 18. The still 1 is heated by the heating pipe 19 to complete the distillation operation of the oil. An insulation box 11 is fixedly connected to the outside of the still 1, and the upper and lower sides of the insulation box 11 are fixedly connected to the connecting pipe 12, the middle of the top connecting pipe 12 is fixedly connected to the water pump 13, and the middle of the bottom connecting pipe 12 is fixedly connected to the water pump 2 14, and the ends of the water pump 13 and the water pump 2 14 away from the connecting pipe 12 are both connected to the cavity 18. The heat transfer oil is filled in the heat preservation box 11, and the heat transfer oil can be transported between the heat preservation box 11 and the cavity 18 through the water pump 13 and the water pump 2 14. A valve 15 is fixedly connected to the middle of the connecting pipe 12, and the connecting pipe 12 is blocked by the valve 15 to store the heat transfer oil in the heat preservation box 11. An exhaust port 16 is fixedly connected to the outside of the still 1, and the exhaust port 16 is connected to the cavity 18. The air pressure inside the cavity 18 is adjusted by the exhaust port 16 to facilitate the normal use of the water pump 13 and the water pump 2 14.

[0032] Working principle: When in use, the petroleum is injected into the still 1, and then the cavity 18 and the still 1 are heated by the heating tube 19, so that the temperature of the petroleum can be increased for the distillation and separation of the petroleum. During this period, the driving motor 2 can be operated to drive the rotating rod 3 to rotate, and then the sleeve rod 6 is rotated under the action of the limit block 9, thereby driving the stirring rod 7 and the stirring plate 8 to rotate, and the stirring of the petroleum inside the still 1 is completed, so as to increase the fluidity of the petroleum and make it better contact with the inner wall of the still 1, thereby increasing the heating speed. Secondly, the electric push rod 4 can be driven to work at the same time to drive the mounting frame 5 to rotate, and then the sleeve rod 6, the stirring rod 7 and the stirring plate 8 and other structures can be driven to move up and down, which can further improve the fluidity of the petroleum, so as to better heat the petroleum, thereby greatly improving the efficiency of distillation and separation.

[0033] Secondly, after the distillation and separation of the petroleum is completed, there is a lot of heat remaining in the middle of the cavity 18 and the inside of the still 1. At this time, the water pump 13 can be used to inject the heat transfer oil stored in the insulation box 11 into the cavity 18, so as to collect the residual heat in the still 1, and then the heat transfer oil in the still 1 can be pumped back by the water pump 2 14 to store the heat. Then, when the still 1 is needed, the heat transfer oil can be injected into the cavity 18 again by the water pump 13, so as to preheat the still 1. This not only reduces energy loss and costs, but also can further reduce the heating time of the petroleum, thereby greatly improving the distillation and separation efficiency.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
