Description

Technical Field

[0001] The invention relates to the technical field of asphalt elongation testing, and in particular to an asphalt elongation collecting device. Background Art

[0002] Asphalt elongation meter is an instrument suitable for measuring the elongation of asphalt and also for testing the elastic recovery of modified asphalt. Its specific operating procedures are as follows:

[0003] (1) The instrument should be placed horizontally indoors at a temperature of 0℃~40℃, relative humidity not exceeding 80%, on a vibration-free, corrosive gas-free floor with good grounding protection. (2) Before use, check the water level in the water tank, which should comply with the test operating procedures. Turn on the power supply after turning off all function switches, and check whether the stirring motor and the extension power motor are running well. (3) Adjust the temperature controller to the required temperature. According to the test requirements and the ambient temperature requirements, start the refrigeration or heating system function switch and start the stirring motor at the same time. During the test, please refer to the thermometer in the water tank. (4) Pull out the handle and rotate it to neutral position, then move the gearbox, place the test mold filled with the sample into the copper cylindrical pin at the extension end of the instrument, push the handle in to make the gear mesh, and then enter the working position. (5) Turn on the power supply of the digital display device on the gearbox, turn on the start switch, the instrument starts working, and the display will show the extension length. During the test, if the asphalt filaments are found to float on the water surface or sink to the bottom of the tank, add alcohol or salt to adjust the specific gravity of the water to the sample before testing. (6) When the asphalt sample is broken or meets the test requirements, press the value switch and the instrument will automatically count the elongation of the sample. After three times, press the value switch to automatically calculate the average value of the three samples. (7) After the work is completed, turn off the power, take out the test mold, pull out the handle to neutral, push the gearbox back; open the drain valve to drain the water in the tank, and wipe the water dry to prevent rust.

[0004] However, the existing asphalt elongation collection device has a fixed size of the test mold during use, and cannot test asphalt of different volumes during use. The function is relatively simple. At the same time, when the test mold is taken out of the water, the water temperature may be too cold or too hot, which makes it impossible for the operator to quickly take out the test mold.

[0016] 1. The asphalt elongation acquisition device can control the motor electric wire shaft to rotate through the control console, and the other end of the wire shaft is positioned by the bearing seat.

[0050] In addition, after the measurement, the solenoid valve 5 is opened, and the water in the test slot 102 can still flow into the water tank 505 through the filter 501 for recycling. The filter 501 can filter impurities in the water. The other side surface of the semiconductor refrigeration plate 502 releases heat, and the heat can be quickly cooled through the heat dissipation fins 503.
