A kind of asphalt sample preparation device and preparation method

Abstract

The invention relates to the technical field of asphalt sample preparation and discloses an asphalt sample preparation device and method. The device comprises a mainframe, a sample preparation jar and a sand bath box mounted in the mainframe, a stirring rod which is mounted in the sample preparation jar and can move up or down, a temperature and humidity sensor mounted in the sample preparation jar, a first drive mechanism for driving the stirring rod to perform stirring, a second drive mechanism for driving the stirring rod to move up or down, and a control device connected with the sand bath box, the temperature and humidity sensor, the first drive mechanism and the second drive mechanism respectively, wherein the sand bath box is used for wrapping the sample preparation jar; a molten asphalt outlet corresponding to the stirring rod is formed in the bottom of the sample preparation jar; an opening / closing mechanism is mounted at the molten asphalt outlet and driven to close or open the molten asphalt outlet when the stirring rod moves up or down. According to the device, full-automatic production of asphalt samples can be achieved.

Description

Technical field [0001] The invention relates to the technical field of asphalt sample preparation, and more specifically, to an asphalt sample preparation device and a preparation method. Background technique [0002] The preparation of asphalt samples is the basis for various performance studies of asphalt. The existing problems in the preparation of asphalt are: there is no special preparation device, manual operation, automatic heating, automatic mixing and automatic discharging cannot be realized. Workers are on duty in real time to monitor the preparation status of the asphalt samples, and during the preparation process, the testers only rely on the testers to observe whether there are bubbles on the surface of the melted asphalt to determine whether the asphalt has been removed from the water. It is easy to make judgment errors. These problems ultimately make the prepared The accuracy of the asphalt samples during the test was severely affected. At the same time, the prior...

Problems solved by technology

[0002] The preparation of asphalt samples is the basis for various performance studies of asphalt. The existing problems in asphalt preparation are: there is no special preparation device, manual operation, and functions such as automatic heating, automatic mixing and automatic discharge cannot be realized. The workers are on duty in real time to monitor the preparation status of the asphalt samples, and during the preparation process, the testers only need to observe whether there are bubbles on the surface of the molten asphalt to judge whether the asphalt has been dehydrated, which is prone to misjudgment. The accuracy of asphalt samples is severely affected when testing

At the same time, in the prior art, there are further disadvantages of poor smoke exhaust performance and no smoke exhaust device, which greatly affects the health of experimenters.
