Description

Technical Field

[0001] This utility model relates to the field of asphalt testing technology, specifically to an asphalt softening point tester. Background Technology

[0002] The asphalt softening point tester is an instrument used to determine the softening point of asphalt. Its working principle is based on the characteristic that asphalt gradually changes from a solid state to a liquid state during the heating process. The asphalt is made into a sample ring of a specified size and placed in a specified heating medium. It is heated at a certain heating rate. When the asphalt sample softens to a certain extent, the steel ball on the test ring will fall under the action of gravity. The temperature at which it falls is the softening point of the asphalt.

[0003] An asphalt softening point tester, authorized by announcement number CN219590225U, includes a rubber base, a tester body mounted on top of the rubber base, and a limiting seat mounted on top of the tester body. Clamping blocks are mounted on both sides of the limiting seat, and anti-slip patches are connected to the inner side of the clamping blocks. An electric push rod is connected to the outer side of the clamping blocks. A support column is fixedly mounted on one side of the tester body, and a lifting plate is mounted on one side of the support column. A stirring motor is mounted on both sides of the upper surface of the lifting plate, and a linkage shaft is connected below the stirring motor. A stirring shaft is mounted on the outer wall of the linkage shaft. Although this asphalt softening point tester can fix the sample ring, the experiment lacks a control group, requiring multiple repeated tests. The test water temperature is difficult to drop quickly, reducing experimental efficiency. Furthermore, the sample ring and steel ball require center calibration to ensure the accuracy of the experimental data.

[0004] To address the above problems, an asphalt softening point tester is proposed. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The asphalt softening point tester provided by this utility model achieves rapid cooling of the test water in the heating chamber by combining a heating chamber mechanism and a cooling mechanism, and by combining heat sinks and cooling fans.

[0028] Specifically, the symmetrical arrangement of two sets of fixed-point test frames 3 enables control testing, reduces the number of repetitions, and improves test efficiency. The combination of heat sink 14 and cooling fan 24 enables rapid cooling of the test water inside the heating chamber 12. The conical arrangement of three sets of inclined support frames 33 ensures the centered placement of the asphalt sample ring, and the three sets of steel ball positioning frames 34 perform center calibration of the steel ball. When the steel ball falls, the conical opening of the inclined support frame 33 allows the steel ball to accurately fall onto the capacitive sensor 32. This asphalt softening point tester has a built-in thermometer and microcontroller, and adds a wireless signal module. When the capacitive sensor 32 detects the falling steel ball, it generates an electrical signal change. This signal can be used as a trigger signal to be transmitted to the microcontroller. After receiving the trigger signal, the microcontroller immediately starts the connected temperature sensor to measure the temperature and records the measured temperature data. At the same time, the wireless communication module sends the temperature data to the terminal device to record the asphalt softening point.
