Description

Pitch system appearance integrated device that fetches a sample

Technical Field

The invention relates to asphalt detection, in particular to an asphalt sampling and sample preparation integrated device.

Background

The asphalt is a black brown complex mixture composed of hydrocarbons with different molecular weights and nonmetal derivatives thereof, is usually in a semi-solid state or a solid state, and has wide application in the fields of roads, buildings and the like. The quality of the asphalt needs to be measured in the stages of development, production, transaction, use and the like so as to verify whether the quality of the asphalt meets the requirements of quality standards such as GB/T15180, JTG F40 ASTM D946 and the like. Before asphalt detection, the asphalt is generally heated to a flowing state and poured into a mold with a specific shape for subsequent detection. For example, patent No. CN201310712525.3 entitled asphalt sample preparation device and preparation method, discloses an asphalt sample preparation device composed of a sample preparation pot and a sand bath box, which is characterized in that a stirring rod which is arranged in the sample preparation pot and can move up and down is arranged at the bottom of the sample preparation pot, a molten asphalt discharge port corresponding to the stirring rod is also arranged at the bottom of the sample preparation pot, and an opening and closing mechanism is also arranged at the molten asphalt discharge port, and the invention is characterized in that: the motor is utilized to drive the stirring rod to stir the molten asphalt, and the molten asphalt is discharged to the detection die under the temperature control in the sand bath box, so that the automatic heating, stirring and discharging are realized. Because the asphalt is solid at normal temperature, the asphalt needs to be heated to a flowing state, stirred uniformly and then poured into the preparation device, and then the asphalt is discharged. The asphalt sample needs an additional heating device and the container is switched for many times, thereby losing the fundamental meaning of the asphalt sample preparation device. The sensor and the stirrer of the device are both arranged in the asphalt, the adhesion is serious, and the subsequent cleaning is troublesome. Current humidity sensors are contact type, i.e. moisture needs to penetrate a sensing component to generate electrochemical action to be converted into a signal. The water content is distributed unevenly in the asphalt due to the incompatibility of the asphalt and the water, the detection result is not accurate, and the detection significance is lost. Meanwhile, the strong adhesiveness of the asphalt defines that the sensor has short service life and high use cost. Conventionally, bitumen is transported at temperatures in excess of 130 ℃ with little moisture inside and therefore less meaningful for moisture testing. Because the asphalt has strong adhesiveness, the asphalt filaments can be pulled very long at a certain temperature, but the asphalt cannot be adhered to the outer surface of the container in the pouring process, and the detection and the subsequent cleaning are influenced. The device is not provided with a special asphalt thread cutting mechanism, asphalt threads such as asphalt molds and containers are easily adhered, and the detection result and the detection efficiency are influenced.
