Description

Technical Field

[0001] This utility model relates to the technical field of viscosity testing, and in particular to a rapid viscosity testing device for asphalt mixtures. Background Technology

[0002] In industrial production and processing, the viscosity of asphalt needs to be measured in order to determine the mixing and paving temperatures of asphalt mixtures. The viscosity of asphalt reflects its ability to resist relative flow within the material under external forces; it is usually expressed as viscosity.

[0003] Existing viscosity testing devices are cumbersome to use, resulting in poor testing results. Therefore, we need to improve existing viscosity testing devices. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies in terms of poor detection results and provides a rapid viscosity detection device for asphalt mixtures with good detection results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid viscosity testing device for asphalt mixtures, comprising a testing instrument, a testing cylinder at the bottom of the testing instrument, a retractable testing column connected to the testing instrument, the testing column being inserted into the testing cylinder, an electromagnetic ring at the top of the testing cylinder, a stabilizing magnetic block at the top of the testing column, the electromagnetic ring corresponding to the stabilizing magnetic block, and a feeding pump connected to the bottom of the testing cylinder.

[0006] The testing device includes a viscosity meter. At the bottom of the meter is a testing cylinder used to hold the asphalt mixture to be tested. A testing column is connected to the lower end of the meter, extending into the testing cylinder. The rotating column transmits rotational data to the meter, which displays the viscosity data, thus completing the viscosity test of the asphalt mixture. A feeding pump is connected to the bottom of the testing cylinder to add asphalt mixture. An electromagnetic ring is located at the top of the testing cylinder, and a stabilizing magnetic block is located at the top of the testing column. When the testing column is inserted into the asphalt mixture in the testing cylinder, the electromagnetic ring is energized, generating a magnetic force. This magnetic force, combined with the stabilizing magnetic block, ensures the stabilizing magnetic ring remains stable, preventing the testing column from shaking during asphalt mixture addition and affecting the viscosity test.

[0007] Preferably, a controller is provided on the top outer side of the detector, and the controller is electrically connected to the detection column. The controller on the top outer side of the detector can control the detection action of the detection column and control the display of the detector, ensuring the normal operation of the detector.

[0008] Preferably, the detector is equipped with a telescopic rod at its top, a connecting block at its bottom, and a rotating motor connected to the connecting block. The rotating motor is connected to the detection column. The telescopic rod at the top of the detector and the connecting block at its bottom have a slot. The rotating motor is connected to the detection column within this slot. The rotating motor rotates, driving the detection column, and in conjunction with a controller, obtains viscosity test data. Simultaneously, the telescopic rod allows adjustment of the depth to which the detection column is immersed in the asphalt mixture, ensuring the normal operation of the detector and improving its effectiveness.

[0009] Preferably, the top of the detection cylinder is provided with a clearance hole, and the side wall of the clearance hole is provided with a mounting groove. The electromagnetic ring is fixedly installed in the mounting groove, and the stabilizing magnetic block is a symmetrically arranged block with an arc-shaped side wall. The electromagnetic ring is fixedly installed in the mounting groove. The stabilizing magnetic block is a symmetrically arranged block, which can be cross-shaped, and its side wall is arc-shaped, concentrically arranged with the electromagnetic ring. Before injecting the asphalt mixture into the detection cylinder, the electromagnetic ring is energized and generates magnetism. The generated magnetic force stabilizes the stabilizing magnetic block installed on the detection column, ensuring the detection column is centered in the detection cylinder. After the asphalt mixture is injected, the electromagnetic ring is de-energized to avoid the influence of magnetic force on viscosity detection, ensuring the viscosity detection effect of the viscosity detection device and thus its usability.

[0010] Preferably, a water bath is provided on the outside of the testing cylinder, and the testing cylinder is placed inside the water bath. A connecting pipe is connected to the bottom of the testing cylinder, and the connecting pipe is connected to the feeding pump. The connecting pipe is equipped with a stop valve. The water bath, located on the outside of the testing cylinder, covers the outside of the testing cylinder. By controlling the temperature of the water in the water bath, the temperature of the testing cylinder can be maintained, thereby maintaining the temperature of the asphalt mixture inside the testing cylinder. This ensures that the temperature does not affect the viscosity test, thus guaranteeing the effectiveness of the viscosity test. Simultaneously, the feeding pump is connected to the connecting pipe at the bottom of the testing cylinder, and a stop valve is installed on this connecting pipe. After the asphalt mixture is fed in, the stop valve is closed to prevent the asphalt mixture from decreasing during viscosity testing, which would affect the test results, thus ensuring the effectiveness of the viscosity test.

[0011] Preferably, a filter screen is provided at the port of the connecting pipe, and an mounting plate is provided at the lower end of the filter screen. The mounting plate is connected to a stirring shaft, and several stirring blades are provided on the outer wall of the stirring shaft. The stirring blades are arranged at an angle. The filter screen at the port of the connecting pipe serves to filter the asphalt mixture injected into the testing cylinder, thereby ensuring the quality of the asphalt mixture entering the testing cylinder and preventing the mixing effect of the asphalt mixture from affecting the viscosity test. Simultaneously, the mounting plate at the lower end of the filter screen, on which the stirring shaft is mounted, has several stirring blades connected to it. The stirring blades are arranged at an angle, allowing the asphalt mixture to agitate before entering the testing cylinder through the connecting pipe, ensuring the mixing effect of the asphalt mixture and preventing the mixing effect from affecting the viscosity test.

[0012] The beneficial effects of this invention are as follows: the cooperation between the electromagnetic ring and the stabilizing magnetic block ensures that the detection column is stably positioned in the center of the detection cylinder when injected, thus avoiding the influence of the detection column's position on viscosity detection, ensuring accurate viscosity detection results, and improving the performance. The filter screen and stirring blades installed in the connecting pipe ensure that the asphalt mixture is fully mixed when injected, avoiding the influence of the asphalt mixture's properties on viscosity detection, ensuring accurate viscosity detection results, and improving the performance. Furthermore, the invention avoids the influence of temperature on viscosity detection during viscosity testing, ensuring the effectiveness of the viscosity detection. Attached Figure Description

The stirring blades 28 are arranged at an angle.

[0025] The working principle of this utility model is as follows: Figure 1-2 As shown, the testing device includes a viscosity meter 1. A testing cylinder 2 is located at the bottom of the measuring instrument 1, which holds the asphalt mixture to be tested. A testing column 3 is connected to the lower end of the measuring instrument 1, extending into the testing cylinder 2. The testing column 3 is rotatable, and its rotation speed transmits the rotational data to the measuring instrument 1. The viscosity data is displayed on the monitor of the measuring instrument 1, thus completing the viscosity test of the asphalt mixture. A feeding pump 6 is connected to the bottom of the testing cylinder 2, allowing the asphalt mixture to be added into the testing cylinder 2. An electromagnetic ring 4 is installed at the top of the testing cylinder 2, and a stabilizing magnetic block 5 is installed at the top of the testing column 3. When the testing column 3 is inserted into the asphalt mixture in the testing cylinder 2, the electromagnetic ring 4 is energized, which generates a magnetic force. The magnetic force works in conjunction with the stabilizing magnetic block 5 to ensure that the stabilizing magnetic ring is in a stable position, thus preventing the testing column 3 from shaking when the asphalt mixture is added, which would affect the viscosity test.

[0026] A controller 10 is provided on the top outer side of the detector 1. The controller 10 can control the detection action of the detection column 3 and control the display of the detector 1 to ensure the normal use of the detector 1.

[0027] A telescopic rod 11 is connected to the top of the testing instrument 1, and a connecting block 12 is connected to the bottom of the telescopic rod 11.

At the same time, the telescopic rod 11 connected to the testing instrument 1 can adjust the depth of the testing column 3 immersed in the asphalt mixture, ensuring the normal use of the testing instrument 1 and improving the effectiveness of the testing device.

[0028] The top of the testing cylinder 2 is provided with a clearance hole 20, and the side wall of the clearance hole 20 is provided with a mounting groove 21.

The water in the water bath 22, by controlling its temperature, can ensure the temperature of the testing cylinder 2, and thus the temperature of the asphalt mixture inside the testing cylinder 2. This ensures that the temperature does not affect the viscosity test and guarantees the effectiveness of the viscosity test. At the same time, a feeding pump 6 is connected to the connecting pipe 23 at the bottom of the testing cylinder 2. A stop valve 24 is installed on the connecting pipe 23.

[0030] A filter screen 25 is installed at the port of the connecting pipe 23. The filter screen 25 can filter the asphalt mixture injected into the testing cylinder 2, thereby ensuring the mixing effect of the asphalt mixture entering the testing cylinder 2 and avoiding the influence of the mixing effect of the asphalt mixture on the viscosity test. At the same time, an installation plate 26 is provided at the lower end of the filter screen 25. A stirring shaft 27 is installed on the installation plate 26. Several stirring blades 28 are connected to the stirring shaft 27. The stirring blades 28 are arranged at an angle.
