Description

Technical Field

[0001] This application relates to the field of road construction, specifically to a device for measuring the carbon emissions of asphalt mixtures. Background Technology

[0002] Asphalt mixtures are a commonly used road construction material, mainly composed of asphalt, aggregates, and possible additives. They are widely used in road paving, airport runways, parking lots, and other pavement projects. Carbon emissions are generated during the production, construction, and use of asphalt mixtures. However, in modern life, people are increasingly concerned about carbon emissions and hope to reduce them in all aspects of life. To achieve this goal, it is hoped that carbon emissions can be reduced in all environmental aspects related to asphalt mixtures. To understand the carbon emissions of asphalt mixture samples, it is often necessary to use experimental equipment to test the carbon emissions of asphalt mixtures, thereby facilitating improvements to the asphalt mixture manufacturing process. Existing measuring devices often can only measure a single sample, and it is difficult to ensure that the measurement conditions are consistent when measuring multiple samples, thus making it difficult to compare the measurement results of different samples.

The support platform has a connecting channel communicating with the air inlet pipe and the space inside the sample cover. The bottom end of the sample cover has an annular flange. The locking unit includes multiple vertical guide rods connected to the base, an upper fixing plate fixedly connected to all the vertical guide rods, an electric lifting rod installed on the upper fixing plate, and a lifting plate driven by the electric lifting rod. The lifting plate has multiple guide holes that cooperate with the vertical guide rods, and the lifting plate is connected to multiple lower pressure plates that can press the annular flange. The measuring unit includes a light emitting unit and a light receiving unit. The sample cover is a transparent cover.

[0005] Furthermore, the measuring unit includes two U-shaped frames installed inside the housing. A drive motor is installed at one end of each U-shaped frame, and a bearing is installed at the other end. A lead screw connects the drive motor and the bearing. Each U-shaped frame has a slide rail and a slide block. The slide block has a groove that mates with the slide rail and a threaded channel that mates with the lead screw. The light emitting unit is installed on the slide block of one of the two U-shaped frames, and the light receiver is installed on the slide block of the other U-shaped frame. The second tube of all sample carrying devices is located between the two U-shaped frames, and the second tube is a transparent tube.

[0006] Furthermore, there are 2-6 sample carriers arranged in a row with equal spacing; the number of the lower pressure plate and the sample carriers are equal and correspond one-to-one.

[0011] This allows the fan to produce a slow airflow, which passes through the sample hood.

[0012] Furthermore, a main pipe is fixed to the side of the box, and a filter screen is provided at the main pipe. The air inlet pipes of all sample carrying units are connected to the main pipe.

[0013] This allows air to slowly enter from the main duct.

[0014] Beneficial effects: The carbon emission measuring device of this application has a sample carrying device that can be used to place asphalt mixture samples on the carrying platform, enabling simultaneous measurement of multiple samples.

[0015] The carbon emission measuring device of this application enables the comparison of multiple samples because multiple samples are located in the same measuring environment, use the same measuring unit, and have similar measuring conditions. Attached Figure Description

The measuring unit includes a light emitting unit 5.4 and a light receiving unit. The sample cover 6.2 is a transparent cover. The measuring unit includes two U-shaped frames 5 installed inside the housing. A drive motor 5.1 is installed at one end of each U-shaped frame 5, and a bearing is installed at the other end. A lead screw 5.2 connects the drive motor 5.1 and the bearing. Each U-shaped frame 5 has a slide rail and a slide block 5.3. The slide block 5.3 has a groove that mates with the slide rail and a threaded channel that mates with the lead screw 5.2. The light emitting unit 5.4 is installed on the slide block 5.3 of one U-shaped frame 5, and the light receiver is installed on the slide block 5.3 of the other U-shaped frame 5. The second tube 6.7 of all sample carrying devices is located between the two U-shaped frames 5, and the second tube 6.7 is a transparent tube.

[0024] The asphalt mixture carbon emission measuring device of this application, due to its multiple sample-bearing devices, can simultaneously hold multiple asphalt mixtures. Because of the corrugated pipe design, the sample cover can be opened to hold the asphalt mixture, and after the sample cover is closed, a locking device can press down and fix the annular flange at the sample cover. A strip light source can simulate sunlight and also serve as a heating element. A fan generates a slow airflow, which passes through the sample cover and exits from the second tube. The measuring unit uses light emitted by the light-emitting unit to pass through the second tube, thereby measuring the gas in the second tube and thus determining the carbon emissions of the asphalt mixture. Driven by a motor, the measuring unit can sequentially pass through the second tubes of multiple sample-bearing devices, thus measuring multiple sample-bearing devices. Because multiple samples are measured in the same environment using the same measuring unit, it is possible to measure and compare multiple samples.
