Description

Technical Field

[0001] This utility model relates to the technical field of experimental equipment, and in particular to an auxiliary device for moisture determination experiments. Background Technology

[0002] In the moisture determination of product quality control, the original method was to weigh the sample using weighing paper and then put it into the moisture measuring instrument. However, this method has problems such as the sample being easily spilled outside during weighing, leading to lower test results and contaminating the instrument; some materials may also have moisture and solvent absorbed by the weighing paper, reducing the accuracy of the weighing results. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing technologies, such as the tendency for samples to spill out and the absorption of moisture and solvents by the weighing paper, which can lead to inaccurate weighing results. It provides an auxiliary device for moisture determination that is less likely to spill samples out and prevents the absorption of moisture and solvents by some materials, thereby improving the accuracy of weighing results.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary device for moisture determination experiments, comprising: A high borosilicate conduit is placed in the middle of the experimental auxiliary device, and the cross-sectional shape of the middle section of the high borosilicate conduit is an outwardly flared arc. A glass funnel is placed on the lower end face of a high borosilicate conduit, and the upper end of the glass funnel is snapped into the high borosilicate conduit. A sealing ring 1 is wrapped around the lower outer surface of the high borosilicate conduit, and the sealing ring 1 is engaged with the outer surface of the high borosilicate conduit. A glass cap is placed on the upper end face of the high borosilicate conduit. The cross-sectional shape of the glass cap is T-shaped. The vertical section of the T-shaped glass cap is placed inside the high borosilicate conduit and is snapped into the high borosilicate conduit. A pressure rubber ball is wrapped around the upper part of the high borosilicate conduit, and the pressure rubber ball is engaged with the outer surface of the high borosilicate conduit.

[0005] In use, first remove the glass lid, then put on the pressure rubber ball. Next, tilt the lower opening of the borosilicate tubing upwards, and then insert the glass funnel into the opening. Pour the weighed sample into the curved part of the borosilicate tubing through the glass funnel. Then, remove the glass funnel, insert the borosilicate tubing into the beaker, and use the sealing ring to form a sealed space with the beaker lid. Let the sample slide into the beaker, and press the pressure rubber ball repeatedly. The blown air will push the sample adhering to the inside of the borosilicate tubing into the beaker. Then, remove the pressure rubber ball and put on the glass lid to form a sealed space. In this way, the test will not be affected by the humidity in the air, and the sample will not be easily spilled outside. Some materials will not be absorbed by moisture and solvent, thus improving the accuracy of the weighing results.

[0006] Preferably, the lower end face of the borosilicate conduit is provided with a groove, and the upper end of the glass funnel is placed in the groove and in contact with the bottom surface of the groove. The glass funnel is engaged with the borosilicate conduit through the groove. The groove facilitates securing the glass funnel.

[0007] Preferably, the lower end face of the borosilicate conduit is beveled. The bevel facilitates the insertion of the borosilicate conduit through the beaker lid into the beaker.

The horizontal section of the T-shape of the sealing ring is placed within the annular groove, and the vertical section of the T-shape is longer than the depth of the annular groove. The sealing ring engages with the borosilicate tubing through the annular groove. The T-shaped cross-section of the sealing ring facilitates adaptation to beaker caps with different openings, and the annular groove can hold the sealing ring in place.

[0009] Preferably, the upper part of the borosilicate conduit is provided with an annular stop, the outer side of which is fixedly connected to the inner side of the borosilicate conduit, and the lower end face of the T-shaped vertical section of the glass cover contacts the upper end face of the annular stop. The annular stop facilitates holding the glass cover in place.

The second sealing ring is placed inside the second annular groove, and the T-shaped vertical section of the glass cover is engaged with the inner surface of the borosilicate conduit through the cooperation of the second sealing ring and the second annular groove. The second sealing ring and the second annular groove facilitate the improvement of the sealing performance of the glass cover.

[0011] Preferably, the outer surface of the T-shaped transverse section of the glass cover is provided with an annular groove three, the cross-sectional shape of which is arc-shaped. The annular groove three increases the friction of the glass cover, making it easier to handle.

The raised ring facilitates the increase of friction between the pressure rubber ball and the high borosilicate conduit, thereby improving the sealing performance of the pressure rubber ball during use.

[0013] The beneficial effects of this utility model are: it prevents samples from spilling out and prevents some materials from absorbing moisture and solvent, thereby improving the accuracy of weighing results; the slot makes it easy to hold the glass funnel in place; the bevel makes it easy for the high borosilicate tubing to pass through the beaker lid and beaker; the T-shaped cross-section of the first sealing ring makes it easy to adapt to beaker lids with different openings, and the first annular groove can hold the first sealing ring; the annular stop makes it easy to support the glass lid; the second sealing ring and the second annular groove improve the sealing performance of the glass lid; the third annular groove increases the friction of the glass lid, making it easier to handle; the convex ring increases the friction between the pressure rubber ball and the high borosilicate tubing, improving the sealing performance of the pressure rubber ball during use.
