Description

A heatable temperature-controlled asphalt sample basin

technical field

The utility model belongs to the technical field of test instruments or equipment for road materials, and in particular relates to a heatable temperature-controlled asphalt sample basin. the

Background technique

Asphalt is a road raw material widely used in road engineering. When conducting asphalt mixture and asphalt-related testing and performance tests in the laboratory, it is usually only necessary to weigh a small amount of asphalt for heating tests. Usually, we use asphalt sample pots to heat, and then use ordinary asphalt sample pots to weigh and test. As we all know, asphalt is a material with strong adhesion. If the asphalt adhered to the metal surface is not heated at room temperature and asphalt solvents such as trichlorethylene and kerosene are used, it is generally difficult to remove it. The cleaning work after the test has brought a lot of inconvenience; although the method of placing the sample pot on the electric stove to heat it is usually used to clean the common sample pot, although the method can achieve the goal quickly, but the tester is easy to burn his hand, and the heating Finally, it should be cleaned with a solvent such as kerosene, which is flammable. This is also a threat to the safety of experimenters. Moreover, the pots used for weighing asphalt are difficult to scrape off due to the adhesion of hot asphalt, resulting in the discrepancy between the quality of the added asphalt and the weighing, which will also cause experimental errors. the

In addition, due to the asphalt mixture and asphalt test, the temperature of the asphalt is very high. After the ordinary heating reaches the required temperature, it is poured into the asphalt basin for weighing, and the temperature will often drop. It is difficult to control the temperature when heating again. And the temperature may be inadvertently too high, causing the asphalt to age. All these will affect the test results of asphalt and asphalt mixture. the

Detailed ways

As shown in Figures 1 and 2, the heatable temperature-controlled asphalt sample pot of the present utility model includes a sample pot 1, a battery, a temperature sensor 4 and a temperature display device 5, and the sample pot 1 includes an outer wall and an inner wall , between the outer wall and the inner wall is a closed vacuum layer 3; the temperature sensor 4 is installed on the bottom of the sample pot 1, and the temperature display 5 and the battery are all installed on the outer wall of the sample pot 1; the inner wall of the sample pot 1 The surface is plated with a nano material layer 2; the temperature sensor 4 and the temperature display 5 are respectively connected to the battery. the

The sample pot 1 is a pot with an inner diameter of 200 mm and an inner height of 100 mm. the

Nano material layer 2 adopts low surface energy coating, such as fluororesin, polysiloxane resin or nano structure, such as binary synergistic nano interface material. The nanomaterial thin layer 2 has a thickness of 0.5 mm, and the vacuum layer 3 has a thickness of 3 mm. the

The outer wall material of the temperature-controlled asphalt sample basin 1 is made of metal materials such as stainless steel. the

The temperature sensor 4 adopts a high temperature resistant sensor as a temperature measuring element, and a DS18B20 digital temperature sensor can be used. the

The temperature display device 5 adopts an LCD digital display screen. In this embodiment, an LCD1602 digital display screen is used. The temperature display device 5 and the sample basin 1 are insulated by a vacuum layer 3 . the

In the utility model, the nano-material layer 2 has extremely strong oleophobicity, and at the same time, the material can withstand a high temperature of 300°C, so it will not adhere to asphalt, and has good durability; at the same time, there is a The thermal insulation layer 3 can effectively prevent the transfer of heat, and the test personnel will not burn their hands during the test. The temperature control sensor 4 and the temperature display 5 are used to monitor the temperature of the asphalt contained, if the temperature is insufficient, the bottom of the heated basin can be directly heated, thereby improving the accuracy of the asphalt temperature control. In turn, the test error caused by the temperature difference is reduced, and the test efficiency is improved. the

The implementation steps of using the present invention to carry out the penetration test are as follows:

1. Place the asphalt taken out in an oven for heating, and after heating to the desired temperature, pour it into a metal asphalt sample basin and weigh it;

2. After the weighing is completed, observe the temperature display, if it is lower than the required temperature, perform direct heating. If it is higher than the required temperature, let it cool down until the required temperature;

3. Pour the so-called asphalt into the corresponding experimental equipment, such as mixing pot, etc., and carry out corresponding experiments.

4. After the experiment, because the nanomaterial thin layer 2 has strong oleophobicity, the asphalt will not adhere to the inner wall of the metal asphalt sample basin 1, and the next test can be carried out only by cleaning it with a rag. the
