Asphalt sample preparation device and 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 relates 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 asphalt preparation are: there is no special preparation device, it is completely manual operation, and functions such as automatic heating, automatic mixing and automatic discharging cannot be realized. , workers are required to be on duty in real time to monitor the preparation status of asphalt samples, and during the preparation process, only by the testers to observe whether there are bubbles on the surface of the molten asphalt to judge whether the asphalt has removed water, it is easy to make mistakes in judgment, these problems eventually make the preparation The accuracy of the asphalt samples tested is seriously affected. At the...

[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, it is completely manual operation, and functions such as automatic heating, automatic mixing and automatic discharging cannot be realized. , workers are required to be on duty in real time to monitor the preparation status of asphalt samples, and during the preparation process, only by the testers to observe whether there are bubbles on the surface of the molten asphalt to judge whether the asphalt has removed water, it is easy to make mistakes in judgment, these problems eventually make the preparation The accuracy of the asphalt samples in the test is seriously affected

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