[0018] For example, Figures 1-2As shown, an extraction device for fiber oil content determination includes a support 1, the support 1 is provided with a heater 2 and a separation tube 8, and a distillation flask 3 is placed on the heater 2. The distillation flask 3 is provided with a thermometer socket 31, and a thermometer 11 is inserted into the thermometer socket 31. The distillation temperature can be controlled by the thermometer. The thermometer socket 31 and the thermometer 11 are sealed by a sealing ring 13 in this embodiment, which improves the sealing performance of the distillation flask.

[0019] The top of the distillation flask 3 is provided with a cap 4, and the cap 4 is provided with a color developing liquid inlet 41, a solution inlet 42 and a pipe joint 43. The cap 4 in this embodiment is a semicircular structure, and the color developing liquid inlet 41, the solution inlet 42 and the pipe joint 43 are evenly distributed on the semicircular surface of the cap 4.

[0020] A rubber bulb dropper 5 is inserted into the color developing liquid inlet 41, and the color developing liquid inlet 41 and the rubber bulb dropper 5 are sealed by a sealing ring 13, which further improves the sealing performance of the distillation flask. A sealing plug 6 is inserted into the solution inlet 42. By opening the sealing plug 6, solvent can be added to the distillation flask 3 without opening the cap 4, which is more convenient to use. The pipe joint 43 is connected with a communication pipe 7, one end of the communication pipe 7 away from the pipe joint 43 is connected with the separation tube 8, and the separation tube 8 is connected with a condenser tube 9.

[0021] Specifically, the top of the separation tube 8 is provided with a liquid inlet, and the bottom of the separation tube 8 is provided with a liquid outlet, and a first valve 81 is installed on the liquid outlet to facilitate liquid discharge. The lower part of the separation tube in this embodiment is provided with a collection cup 12.

[0022] Specifically, the condenser tube 9 is fixed on the top of the separation tube 8, and the condenser tube 9 includes an inner straight pipe 91 and an outer straight pipe 92 sleeved on the outside of the inner straight pipe 91. The lower end of the inner straight pipe 91 is connected with the liquid inlet, so as to communicate with the inner cavity of the separation tube 8. The outer straight pipe 92 is provided with a cooling liquid inlet 93 and a cooling liquid outlet 94. The upper end of the inner straight pipe 91 is provided with a second valve 95 to facilitate air discharge. The condenser tube 9 adopts a straight pipe type condenser tube, so that the mixed liquid after condensation can completely flow into the separation tube 8 without adhering to the wall of the condenser tube, thereby improving the accuracy of oil content determination.

[0023] The support 1 in this embodiment is provided with a fixing bracket 10 for fixing the separation tube 8 and the condenser tube 9, and the fixing bracket 10 includes a vertical rod 102 and two pipe clamps 101 installed on the vertical rod, and the two pipe clamps 101 clamp and fix the separation tube 8 and the condenser tube 9 respectively.

[0024] Working principle: the fiber to be tested is put into the distillation flask 3, water solvent is added into the distillation flask 3 through the solution inlet 42, and a few drops of color developing agent are added into the distillation flask 3 through the rubber head dropper 6, the color developing agent is dissolved in water, the color developing agent can be selected as chlorinated cetyl pyridine, which is green when dissolved in water, and becomes red when contacting with the oily component, so that the color change of the color developing agent can be observed to directly judge whether the oil exists in the fiber. The distillation flask 3 is heated by the heater 2, the heated oil-water mixed steam enters the separation tube 8 through the connecting tube 7, and enters the inner straight tube 91 of the upper condenser tube 9 through the separation tube 8, the cooling liquid is added into the outer straight tube 92 of the condenser tube, the steam becomes liquid after being cooled and condenses on the wall of the inner straight tube 91, and the mixed liquid flows back to the separation tube 8 along the wall, because the specific gravity of the oil is light, the oil floats on the water, when the distillation is finished, the first valve 81 at the bottom is opened to sequentially discharge the water solution and the oil, and the first extraction of the oil is completed. Then the water solvent and the color developing agent are continuously added into the distillation flask 3, if the color developing agent still changes color, the distillation is continuously carried out for the second extraction. In this way, until the color developing agent does not change color, it is indicated that there is no oil in the fiber, at this time, the distillation extraction can be stopped to avoid invalid work. The extraction method can directly judge whether the oil in the fiber is completely extracted, and the accuracy is greatly improved.
