Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a quartz wool filling device for lining tubes. Background Technology
[0002] In the quantitative detection of dust pollution in factory workshops, a liner filled with quartz wool is used to draw in air from the workshop. Based on the intake flow rate, the amount of dust contained in a unit volume of air is detected by a chromatograph to determine the dust pollution level of the factory workshop.
[0003] The liner is a double-opening transparent glass tube. Before the testing process, the glass liner must be filled with quartz wool at a specified position and length. The existing method is to weigh a certain amount of quartz wool, manually insert the quartz wool into the liner with a bamboo stick or a thin stick with a smooth surface, and then measure the filling position with a ruler.
[0004] Current methods for filling the column with silica wool are not standardized, resulting in uneven sample dispersion and voids created during the filling process. These voids allow tiny particles to enter the chromatographic column during injection, causing blockage of the gas chromatograph. Inaccurate filling placement is also a problem; the filling position is typically 1-2 cm below the injection needle tip. Being too far or too close can lead to significant errors in the analytical results. Furthermore, operational errors during the filling process can easily cause the glass liner to fall and break.

[0028] The following detailed description of the specific implementation method of the lining quartz wool filling device of this utility model is provided in conjunction with the accompanying drawings.
[0029] See appendix Figure 1The quartz wool filling device for the liner includes a base 1, on which a support column 4 is set. The diameter of the support column 4 is smaller than the inner diameter of the liner 7 and matches the inner diameter of the liner 7. The support column 4 is used to insert and fix the liner 7. The height of the support column 4 is 1 to 2 times the diameter of the liner 7. A positioning ruler 5 is set on the side of the support column 4. The positioning ruler 5 is vertically fixed on the base 1. When the liner 7 is fixed on the support column 4, the positioning ruler 5 is close to the liner 7. A filling mark 6 is marked on the positioning ruler 5. The filling mark 6 is used to indicate the filling position of the quartz wool in the liner 7.
[0030] The base 1 has a placement hole 2 for placing quartz wool, and a cover plate 3 is provided on the placement hole 2. An anti-slip block 8 can be installed under the base 1 for safer placement on the workbench.
[0031] When filling the liner tube 7 with quartz wool, first place the liner tube on the support column 4, then take out the quartz wool from the placement hole 2 using the filling tool and fill it into the liner tube 7. During the filling process, the accuracy of the filling is achieved by referring to the ruler.
[0032] See appendix Figure 2 , 3 In the appendix Figure 1 Based on this, there are two positioning rulers 5, which are arranged at an angle on the side of the support column 4. The filling marks 6 on the two positioning rulers 5 are located at the upper middle and lower middle positions, respectively. The filling marks 6 on the positioning rulers 5 can also be used as scales.
