[0017] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.

[0018] Embodiment 1

[0019] As Figures 1 to 3As shown in the figure, the fiber grease rapid extraction instrument of this embodiment includes a base 1, a bracket 2, an evaporating dish 3, an extraction tube 4, a gland 5, a pressing rod 6, a weight 7, a heating ring 8, and a pressing ring 9. The bracket 2 is installed on the base 1. The extraction tube 4 and the pressing rod 6 are vertically arranged on the bracket 2. The gland 5 is installed on the bracket 2. The weight 7 is placed on the base 1. Inside the base, there is a circuit board (not labeled) and a heating plate 15. On the surface of the base, there are a timing button 11, a control screen 12, and a USB interface 13. The heating plate 15, the timing button 12, the control screen 12, and the USB 13 interface are all electrically connected to the circuit board. The USB interface 13 is electrically connected to an external electronic balance through a USB Bluetooth transmission receiver, etc. The heating ring 8 is installed on the base 1 and is located below the extraction tube 4, and its bottom is connected to the heating plate 15. The evaporating dish 3 is installed on the heating ring 8. The pressing ring 9 presses on the evaporating dish 3. Among them, a card slot 21 is provided at the front end of the bracket 2, and the upper end of the extraction tube 4 is stuck in the card slot 21, which is convenient for fixing the extraction tube 4. The circuit board is used for main control, and the control screen 12 is convenient for adjusting various parameters, etc. Press the timing button 11, and the circuit board controls the heating ring 8 to heat the evaporating dish 3 and displays the time parameter, temperature parameter, etc. on the control screen. The above-mentioned circuit board, timing button 11, control screen 12, USB interface 13, etc. all adopt common components, and their electrical connections are common circuit connection relationships.

[0020] During operation, approximately 2 g of the sample is randomly and evenly extracted, accurate to 0.1 mg. Use tweezers to place the sample into the extraction tube 4 of the fiber grease extractor and slightly compact it with the pressure rod 6. Place the evaporating dish 3 that has been cleaned, dried to a constant weight (i.e., the difference in weighing between two consecutive times does not exceed 0.05% of the latter weighing), and cooled to room temperature on the heating ring 8 of the instrument and fix it. The heating temperature is higher than the boiling point of the solvent. Use a pipette to transfer approximately 15 ml (enough to submerge the sample) of the solvent and slowly add it to the extraction tube 4 of the fiber grease extractor. Press the pressure cap 5 to stop the flow, and soak for 10 minutes. Remove the pressure cap 5, and the solution in the extraction tube 4 slowly drips into the evaporating dish 3, paying attention to preventing liquid overflow, splashing, and over-boiling. When the solution in the extraction tube 4 no longer drips, place the pressure rod 6 into the extraction tube 4 and squeeze until no more liquid droplets flow out. Use a long hook needle and tweezers to turn over and loosen the squeezed sample, and transfer approximately 10 ml (enough to submerge the fiber) of the solvent to repeat the above steps. When the evaporation of the second extraction liquid is completed, continue to heat the evaporating dish for 10 minutes. After that, take it out and place it in a desiccator to cool to room temperature, weigh it accurately to 0.1 mg, and finally obtain the relevant parameters and calculate the oil content according to the calculation formula and display it on the control panel. The fiber grease rapid extractor in this embodiment integrates extraction and heating, can rapidly extract fiber grease, and directly calculates the oil content by connecting to an external electronic balance through a USB interface to obtain the relevant mass parameters of the evaporating dish, realizing the integration and intelligence of fiber grease extraction, effectively improving the test efficiency. In addition, the heating plate is built into the base, and the heating ring is connected to the heating plate and externally placed on the base to avoid touching the heating plate and improve safety.

[0021] In this embodiment, a status light 14 is provided on the bracket 2. The status light 14 is electrically connected to the circuit board and is used to indicate the heating status. The number of the heating rings 8 is four, and the four heating rings 8 are evenly distributed on the base 1, facilitating multiple extraction operations. The number of the timing buttons 11 is four, and the number of the status lights 14 is four. The timing buttons 11 are located in front of the corresponding heating rings 8, and the status lights 14 are located behind the heating rings 8. Each heating ring corresponds to a timing button and a status light, facilitating independent control of each working station. The extraction tube 4, the pressure cap 5, and the pressure rod 6 are evenly distributed on the bracket 2, facilitating the removal of the pressure cap 5 and the pressure rod 6.

[0022] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
