Description

Technical Field

[0001] The utility model relates to the technical field of highway asphalt experimental instruments and equipment, in particular to an asphalt standard viscosity detection device. Background Art

[0002] In recent years, with the increasing demand for high-grade highway construction, the requirements for asphalt are getting higher and higher. When the viscosity of asphalt is not enough, it will cause insufficient bonding between asphalt, aggregate and mineral powder, which will lead to the decline of high-temperature performance of asphalt mixture, and easily form rutting, pushing and other diseases, shortening the service life of flexible pavement, so the standard viscosity test of asphalt is particularly important.

[0003] At present, the test procedures for asphalt and asphalt mixtures in highway engineering stipulate that in the standard viscosity test of asphalt, the asphalt must first be heated by an instrument and then transported into the curing pipe. During the transportation of the heated asphalt, the temperature of the asphalt will change, thereby reducing the test accuracy of the asphalt viscosity test. Therefore, we propose a viscosity test to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0022] The present application provides an asphalt standard viscosity detection device, which is mainly used to solve the problem in the prior art that the temperature of asphalt changes during the transportation of heated asphalt, thereby reducing the test accuracy of asphalt viscosity detection, and provides the following technical solutions. Figure 1-Figure 4 Make a detailed description:

[0023] A device for detecting standard viscosity of asphalt, comprising:

[0024] A water bath 1, wherein support legs are arranged at four corners of the bottom surface of the water bath 1, and a bearing plate 2 is fixedly arranged at the bottom of the support legs;

[0025] The detection mechanism 3 includes a folded line tube 301 which is arranged at equal intervals inside the water bath 1. The upper and lower ends of the folded line tube 301 respectively penetrate the top wall and the side wall of the water bath 1. The upper end of the folded line tube 301 is connected with a heating bucket 302. A flamethrower 303 is installed on one side of the top of the water bath 1. The flamethrower 303 leads outwardly multiple groups of flame heads 304. The flame heads 304 correspond to the positions of the heating bucket 302. A material blocking column 305 is inserted into the interior of the heating bucket 302. The bottom end of the material blocking column 305 extends into the interior of the folded line tube 301. A mercury thermometer 306 is fixedly embedded in the interior of the material blocking column 305.

[0026] The temperature control component 4 is arranged on the water bath 1 and is used to control the water temperature in the water bath 1 to be in a constant temperature state.

[0027] The specific implementation process and principle of the asphalt standard viscosity testing device are as follows:

[0028] When measuring the viscosity of asphalt, engineers first insert the blocking column 305 into the interior of the heating bucket 302 to block the upper port of the folded tube 301, then put the asphalt into the interior of the heating bucket 302, and then turn on the flamethrower 303. The fire sprayed by the flamethrower head 304 can heat the asphalt. By observing the reading of the mercury thermometer 306, when the asphalt reaches the specified temperature, the blocking column 305 is pulled out to allow the asphalt to flow into the folded tube 301. By detecting and observing the flow of the asphalt sample in the folded tube 301, the standard viscosity value of the asphalt is calculated according to the flow speed and time. When the device is used for asphalt concentration detection, there is no need to transfer the heated asphalt, thus avoiding the influence of external temperature and ensuring the accuracy of the test.

[0029] like Figure 1 As shown, in some embodiments, the temperature control component 4 includes an electric heating rod 401 installed on one side of the water bath 1, the heating end of the electric heating rod 401 extends into the interior of the water bath 1, a temperature sensor 402 is installed on the top of the water bath 1, and a control panel 403 is installed on the front side of the water bath 1. The input ends of the electric heating rod 401 and the temperature sensor 402 are electrically connected to the output end of the control panel 403. More specifically, the input ends of the electric heating rod 401 and the temperature sensor 402 are electrically connected to the output end of the control panel 403, which means that the control panel 403 can control the heating power of the electric heating rod 401 to achieve the desired constant temperature state. Through the settings on the control panel 403, you can set the desired temperature and monitor the feedback signal of the temperature sensor 402 to adjust the heating power of the electric heating rod 401 in real time so that the water temperature remains within the set target temperature range.

[0030] like Figure 3 As shown, in some embodiments, a receiving trough 5 is provided on the surface of the supporting plate 2 at the lower end of the folded line tube 301. More specifically, when performing a standard viscosity test of asphalt, the asphalt sample will flow into the interior of the folded line tube 301 after being heated. When the asphalt sample flows out from the lower end of the folded line tube 301, it will be guided to the receiving trough 5. This can avoid waste and contamination of the asphalt sample. The receiving trough 5 acts like a funnel, which can help collect the asphalt sample together to facilitate subsequent analysis and processing.

[0031] like Figure 4 As shown, in some embodiments, the blocking column 305 is a stainless steel column, and its bottom end is tapered. More specifically, when conducting a standard viscosity test of asphalt, the blocking column 305 is placed at the upper port of the folded tube 301 to prevent the asphalt sample from overflowing from the upper port, thereby ensuring the safety and reliability of the test process. Since the bottom of the blocking column 305 is tapered, it can better adapt to the shape of the upper port of the folded tube 301, thereby effectively preventing the asphalt sample from leaking.

[0032] like Figure 3 As shown, in some embodiments, a cross 307 is fixedly provided in the middle of the material blocking column 305. More specifically, the function of the cross 307 is to support the material blocking column 305 so that it can be stably maintained in a vertical state.

[0033] like Figure 1 As shown, in some embodiments, a transparent observation window 101 is provided on one side of the top of the water bath 1. More specifically, the transparent observation window 101 is usually made of a transparent material (such as glass or plastic) and has high transparency and heat resistance. It allows the user to clearly see the flow state of the asphalt inside the water bath 1.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
