Description

Technical Field

[0001] This utility model relates to the field of asphalt material production, and in particular to a viscosity measuring device for asphalt material production. Background Technology

[0002] As an important road construction material, the viscosity of asphalt is a key indicator for evaluating its high-temperature performance, flow characteristics, and workability. In the production, storage, transportation, and construction of asphalt materials, accurate and timely measurement of its viscosity is of vital importance for ensuring product quality, optimizing production processes, and ensuring the performance of the final road surface. In particular, viscosity is a core quality control parameter in the production of special materials such as modified asphalt and high-viscosity asphalt.

[0003] Currently, rotational viscometers are the most widely used instruments for measuring asphalt viscosity in industrial production and laboratory research. Their working principle involves calculating viscosity by measuring the torque experienced by a rotor rotating uniformly in a constant-temperature asphalt sample. While these devices offer high measurement accuracy, they have significant shortcomings in actual production line applications. Offline measurement results in poor timeliness, requiring manual sampling, transfer to a laboratory for constant temperature measurement, and a cumbersome and time-consuming process. Furthermore, they cannot reflect the dynamic changes in asphalt viscosity on the production line in real time, leading to delays in quality control. Therefore, we propose a viscosity measuring device for asphalt material production to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a viscosity measuring device for asphalt material production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A viscosity measuring device for asphalt material production includes a sampling container. A top cover is screwed onto the upper surface of the sampling container. Two supports are mounted on the upper surface of the top cover, and a rotational viscometer is installed between the two supports. A rotor is provided inside the sampling container. A through hole is opened on the upper surface of the top cover. The output end of the rotational viscometer is connected to the top of the rotor through a connecting post. A sampling valve is fixedly connected to the outer surface of the sampling container, and an adjustment component is installed on the outer surface of the sampling container.

[0006] In a further embodiment, one end of the sampling valve is fixedly connected to a sampling tube, the top end of the sampling tube is fixedly connected to a three-way connector, and the outer surface of the sampling tank is provided with a liquid level window.

[0007] In a further embodiment, the bottom end of the sampling container is threaded with a discharge cover, and a rotating rod is fixedly connected to the outer surface of the discharge cover.

[0008] In a further embodiment, the adjustment assembly includes a support plate fixed to the outer surface of the sampling container, and a fixing sleeve is fitted onto the outer surface of the support plate.

[0009] In a further embodiment, two threaded sleeves are installed on the outer surface of the fixing sleeve, and each threaded sleeve has a locking screw threaded inside, with one end of each locking screw contacting the outer surface of the support plate.

[0010] In a further embodiment, a support base is fixedly connected to the bottom end of the fixing sleeve, and two fixing holes are formed on the upper surface of the support base.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device integrates a rotational viscometer directly into the sampling tank and connects to the production line via a sampling tube and a T-connector. This allows the device to directly obtain asphalt samples from the production pipeline for immediate measurement. Since the sample is measured directly inside the sampling tank, it avoids temperature changes and potential phase separation during sample transfer and transportation, as is common in traditional methods. This ensures that the measurement conditions are highly consistent with the production line operating conditions, enabling real-time monitoring of asphalt viscosity on the production line. This significantly shortens the quality feedback cycle and facilitates timely adjustments to process parameters by production personnel, solving the core problems of "offline measurement with poor timeliness" and "lagging quality control" in the background technology.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4In this utility model, a viscosity measuring device for asphalt material production includes a sampling tank 1. A top cover 8 is screwed onto the upper surface of the sampling tank 1. Two supports 6 are mounted on the upper surface of the top cover 8, and a rotational viscometer 5 is installed between the two supports 6. A rotor 15 is provided inside the sampling tank 1. A through hole 7 is opened on the upper surface of the top cover 8. The output end of the rotational viscometer 5 is connected to the top of the rotor 15 through a connecting post 14. A sampling valve 2 is fixedly connected to the outer surface of the sampling tank 1. A sampling tube 3 is fixedly connected to one end of the sampling valve 2. A three-way connector 4 is fixedly connected to the top of the sampling tube 3. A liquid level window 10 is provided on the outer surface of the sampling tank 1. The rotational viscometer 5 is directly integrated into the sampling tank 1 and connected to the production line process through the sampling tube 3 and the three-way connector 4. This allows the device to directly obtain asphalt samples from the production pipeline for immediate measurement. Since the sample is measured directly inside the sampling tank 1, the temperature changes and possible phase separation during sample transfer and transportation in traditional methods are avoided, ensuring that the measurement conditions are highly consistent with the production line conditions.

[0021] An adjustment assembly 9 is installed on the outer surface of the sampling container 1. The adjustment assembly 9 includes a support plate 902 fixed to the outer surface of the sampling container 1. A fixing sleeve 901 is fitted onto the outer surface of the support plate 902. Two threaded sleeves 903 are installed on the outer surface of the fixing sleeve 901. Each threaded sleeve 903 has a locking screw 904 threaded inside. One end of each locking screw 904 is in contact with the outer surface of the support plate 902. By adjusting the assembly 9, the height and position of the entire device can be easily adjusted and fixed to adapt to different installation environments. A discharge cover 13 is threadedly connected to the bottom end of the sampling container 1. A rotating rod 12 is fixedly connected to the outer surface of the discharge cover 13. When the rotor 15 needs to be cleaned or replaced, the top cover 8 can be opened for operation. After the measurement is completed, the discharge cover 13 can be unscrewed for thorough cleaning. The maintenance process is simple and quick. The liquid level window 10 makes it easy to observe the sample liquid level in the tank. A support base 11 is fixedly connected to the bottom end of the fixing sleeve 901. Two fixing holes 16 are opened on the upper surface of the support base 11. The support base 11 and the fixing holes 16 can be stably installed on the platform. The locking screw 904 in the adjustment component 9 can ensure that there is no shaking after fixing, thus ensuring the stability of the viscometer during the measurement process.

[0022] The working principle of this utility model is as follows: By using the fixing holes 16 on the support base 11, the entire device is securely installed at a suitable position next to the asphalt production pipeline. Loosen the locking screw 904 of the adjusting component 9, slide the fixing sleeve 901 up and down, adjust the height of the sampling tank 1 to a suitable position, and then tighten the locking screw 904 to fix it. Connect the sampling tube 3 to the bypass or sampling point of the asphalt production process through the tee connector 4 to ensure that the valve can control the flow of asphalt.

[0023] Open sampling valve 2 to allow the high-temperature asphalt on the production line to flow into sampling tank 1 through sampling tube 3. Observe through liquid level window 10. When the asphalt sample reaches the predetermined liquid level, ensuring that the rotor 15 is submerged at the specified scale, close sampling valve 2 to stop sampling. Let the sample stand in sampling tank 1. Start rotational viscometer 5. The output end of rotational viscometer 5 drives rotor 15 to start rotating in the asphalt sample at a set constant speed through connecting column 14. Rotator 15 will be subject to resistance torque when rotating in viscous asphalt. This torque value is accurately detected by rotational viscometer 5. Rotational viscometer 5 converts the torque value into a viscosity value according to the internal sensor and calibration program, and displays or outputs it directly. After obtaining a stable viscosity reading and recording it, stop rotational viscometer 5. Rotator 15 stops rotating. Rotate rotating rod 12, unscrew discharge cover 13, discharge the residual asphalt in the tank and perform special treatment.
