AI Technical Summary
When the emulsion is poured into the existing asphalt emulsion sample container, it slides down the cup wall and sticks to the inner wall of the cup rim, which affects the insertion of the cork and makes the cork dirty.
A sample container for asphalt emulsion, including a vessel and a vessel holder, was designed. The vessel has a transparent glass test tube and a flow guiding structure. The flow guiding hood is plugged into the upper port of the test tube. A limiting plate structure prevents shaking. The inner wall of the flow guiding hood and the outer wall of the flow guiding nozzle are used for flow guiding to avoid the emulsion from contaminating the upper edge of the test tube.
This method ensures that the asphalt emulsion is smoothly introduced into the test tube, preventing the emulsion from staining the upper edge of the test tube and ensuring a clean cork seal.

Abstract
Description
Technical Field
[0001] This utility model relates to a sample container, and more particularly to an asphalt emulsion sample container. Background Technology
[0002] Emulsion asphalt, more commonly known as emulsified asphalt, is a water-in-oil (O / W) type asphalt emulsion formed by dispersing viscous asphalt in microdroplets in water containing emulsifiers and stabilizers through thermal melting and mechanical action. Asphalt emulsion compositions are mainly used in the road construction industry. During the research and development of asphalt pavement materials, the stability of the asphalt emulsion needs to be tested.
[0003] When determining the storage stability of various emulsified asphalts, the asphalt emulsion needs to be placed in a test tube and allowed to settle. After a period of settling, the evaporation residue content of the emulsified asphalt segments in the test tube needs to be determined. Before the experiment, the experimenter will place a beaker containing emulsified asphalt against the opening of the test tube, with the test tube slightly tilted at a certain angle to ensure that the asphalt can flow fully into the test tube along the tube wall. After the emulsion is poured to the opening of the test tube and the beaker is removed, the emulsion that slides down the beaker wall will stick to the inner wall of the beaker rim, affecting the insertion of the cork and also soiling the cork.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an asphalt emulsion sample container, including a vessel and a vessel holder. The vessel includes a test tube 3, and the outer wall of the test tube 3 is provided with two sample outlets 6, which are connected to the test tube 3. The upper end of the test tube 3 is provided with a flow guiding structure.
[0024] Seal both sample outlets 6 with corks. Pour the asphalt emulsion to be tested into test tube 3 through the upper end of test tube 3. Tilt test tube 3 slightly to ensure that the emulsion flows fully into test tube 3. Stop adding emulsion when it reaches 250ml, and then seal the upper end of test tube 3 with corks. When taking samples, simply open the corks at the corresponding sample outlets 6.
[0025] The bracket includes a column 1 and a base 2. The column 1 is fixedly connected to the upper end of the base 2. The column 1 is provided with a limiting plate structure on the outside of the column body to prevent the test tube 3 from shaking.
[0026] After the asphalt emulsion is added to 250ml, place test tube 3 on base 2. The limiting plate structure outside the column 1 will limit the test tube 3.
[0027] The flow guiding structure includes a flow guiding hood 11, the outer wall of which is conical. The flow guiding hood 11 is plugged into and connected to the upper port of the test tube 3. A flow guiding nozzle 15 is provided at the lower end of the flow guiding hood 11. The upper end of the flow guiding nozzle 15 is fixedly connected to the flow guiding hood 11. The lower end of the flow guiding hood 11 coincides with the axis of the test tube 3.
[0028] The asphalt emulsion is added through the flow guide 11 at the upper end of the test tube 3. The asphalt emulsion can flow into the test tube 3 along the inner wall of the flow guide 11 and the outer wall of the flow guide 15. After adding 250ml, the asphalt emulsion will overflow the flow guide 15. At this time, the flow guide 11 and the flow guide 15 can be pulled out together. When the upper end of the test tube 3 is sealed, the asphalt emulsion will not stick to the upper edge of the test tube 3.
[0029] It is worth further explaining that test tube 3 is made of transparent glass, and the outer wall of test tube 3 has a scale 16. The asphalt emulsion is poured into test tube 3, and the experimenter observes the change in the volume of the emulsion in test tube 3 through the scale 16 on the outside of test tube 3.
[0030] For details on the structure of the limiting plate, please refer to the following description.
[0031] The limiting plate structure includes a first limiting plate 4 and a second limiting plate 8. The second limiting plate 8 is placed above the first limiting plate 4. The first limiting plate 4 is sleeved on the outside of the column 1 and fixedly connected to the column 1. The second limiting plate 8 is sleeved on the outside of the column 1 and slidably connected to the column 1. A positioning component is provided at the connection between the second limiting plate 8 and the column 1. A groove 5 is provided on the side of the first limiting plate 4 and the second limiting plate 8 near the test tube 3 to allow the test tube 3 to be inserted.
[0032] Test tube 3 is placed on the upper end of base 2, on one side of column 1. When placing test tube 3, insert test tube 3 into the groove 5 opened on the side of the first limiting plate 4 and the second limiting plate 8. The first limiting plate 4 limits test tube 3 from the lower half through the groove 5, and the second limiting plate 8 limits test tube 3 from the upper half through the groove 5. Test tube 3 placed on the upper end of base 2 will not shake.
[0033] The height of the second limiting plate 8 is adjustable. When adjusting the height of the second limiting plate 8, the positioning component can be released from fixing the second limiting plate 8. Specifically, the positioning component includes a sliding sleeve 9, which is sleeved on the outside of the column 1 and slidably connected to the column 1. The upper end of the sliding sleeve 9 is fixedly connected to the second limiting plate 8. A tensioning bolt 7 is provided on the outside of the sliding sleeve 9. The tensioning bolt 7 passes through the sliding sleeve 9 and contacts the outer wall of the column 1. The tensioning bolt 7 is threadedly connected to the sliding sleeve 9.
[0034] When fixing the second limiting plate 8, rotate the tension bolt 7 to screw the tension bolt 7 into the sliding sleeve 9. The tension bolt 7 contacts the column 1 and squeezes the column 1. The friction between the column 1 and the tension bolt 7 increases, and the sliding sleeve 9, together with the second limiting plate 8, is fixed to the outside of the column 1.
[0035] When adjusting the position of the second limiting plate 8, rotate the tension bolt 7 to unscrew the sliding sleeve 9. The tension bolt 7 will no longer press against the column 1, and the fixation between the sliding sleeve 9 and the column 1 will be released. The second limiting plate 8 can slide up and down along the column 1.
[0036] The flow guide 11 is fixed to the test tube 3 by insertion and removal. To prevent the flow guide 11 from being lost after use, in a preferred embodiment, the upper end of the test tube 3 is provided with an elastic collar 12. The elastic collar 12 is sleeved on the outside of the test tube 3 and slidably connected to the test tube 3. A connecting strap 10 is fixedly connected to the outside of the elastic collar 12, and the end of the connecting strap 10 away from the elastic collar 12 is fixedly connected to the flow guide 11. When the flow guide 11 is not in use, the elastic collar 12 can be sleeved on the outside of the test tube 3, and the elastic collar 12 is fixed to the flow guide 11 by the connecting strap 10, so the flow guide 11 will not be lost.
[0037] The flow guide 11 is fixed to the upper port of the test tube 3 by a plug-in method. To facilitate the removal of the flow guide 11 from the upper port of the test tube 3, in a preferred embodiment, the upper end of the flow guide 11 is provided with at least two protrusions 14, which are fixedly connected to the outer side of the flow guide 11. When removing the flow guide 11 from the upper port of the test tube 3, the flow guide 11 can be quickly pulled by placing a finger on the lower end face of the protrusion 14.
[0038] To improve the stability of the base 2 when placed on a table, multiple rubber pads 13 are provided at the lower end of the base 2, and the rubber pads 13 are fixedly connected to the base 2. The base 2 fixed to the lower end of the rubber pads 13 can increase the friction between the base 2 and the table, so that the bracket will not slip when the table shakes.
[0039] How this application works:
[0040] Seal the two sample outlets 6 with a cork. Pour the asphalt emulsion to be tested into test tube 3 through the upper end of test tube 3. Tilt test tube 3 slightly to ensure that the emulsion can flow fully into test tube 3 and elastic collar 12. Stop adding the emulsion when it reaches 250ml. Seal the upper end of test tube 3 with a cork. The asphalt emulsion is added through the flow guide 11 at the upper end of test tube 3. The asphalt emulsion can flow into test tube 3 along the inner wall of the flow guide 11 and the outer wall of the flow guide 15. After adding 250ml, the asphalt emulsion will overflow the flow guide 15. At this time, the flow guide 11 and the flow guide 15 can be pulled out together. When sealing the upper end of test tube 3, the asphalt emulsion will not stick to the upper edge of test tube 3.
