Description

Technical Field

[0001] This utility model relates to the field of asphalt temperature measurement technology, specifically a temperature measuring device for controlling the temperature of special asphalt. Background Technology

[0002] In the production, storage and use of specialty asphalt, precise control of asphalt temperature is a key factor in ensuring its performance and quality. Temperature changes in asphalt directly affect important indicators such as viscosity, fluidity and chemical reactivity. Therefore, it is necessary to monitor the temperature of the asphalt in the tank in real time using a reliable temperature measuring device, and to make precise adjustments to the heating or cooling system based on this.

[0003] However, traditional temperature measuring devices can usually only measure the temperature within a certain area inside the tank. Due to the poor fluidity of special asphalt, local temperature data cannot represent the overall temperature state, which may cause the temperature control system to make incorrect adjustments based on partial temperature information, affecting asphalt quality and production efficiency. In addition, some devices install multiple temperature measuring points to obtain more temperature data, which increases the installation cost and maintenance difficulty of the device. To address the above problems, the inventors have proposed a temperature measuring device for special asphalt temperature control to solve the above problems. Utility Model Content

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.

[0018] Example: Figure 1-4 As shown, this utility model provides a temperature measuring device for special asphalt temperature control, including an asphalt tank 1, a tank cover 2 at the top of the asphalt tank 1, the asphalt tank 1 and the tank cover 2 are connected by bolts and nuts 11, a rotating rod 3 is movably inserted through the top of the tank cover 2, a temperature measuring rod 4 is fixedly installed on one side of the bottom end of the rotating rod 3, a rotating assembly 5 is provided at the top of the tank cover 2, the rotating assembly 5 is used to drive the temperature measuring rod 4 to rotate, and a vertical moving assembly 6 is provided at the top of the tank cover 2 near the rotating assembly 5, the vertical moving assembly 6 is used to drive the temperature measuring rod 4 to move vertically.

[0019] The rotating assembly 5 includes a servo motor 51, with a drive wheel 52 fixedly connected to the drive end of the servo motor 51. A rotating column 53 is rotatably connected to the top center of the can lid 2, and a driven wheel 54 is fixedly connected to the outer side of the rotating column 53. The drive wheel 52 and the outer side of the driven wheel 54 are connected by a belt drive.

[0020] By adopting the above technical solution, the servo motor 51 drives the drive wheel 52 to rotate. The drive wheel 52 meshes with the driven wheel 54, which in turn drives the rotating column 53 and the rotating rod 3 to rotate, thereby driving the temperature measuring rod 4 to rotate, and detecting the temperature in different areas inside the asphalt tank 1.

[0021] The vertical moving assembly 6 includes a gear 61, which is fixedly connected to the top outer side of the rotating column 53. A double-acting screw 64 is rotatably connected to the top of the asphalt tank 1 near the gear 61. A moving plate 65 is threadedly connected to the outer side of the double-acting screw 64. The top of the rotating rod 3 is rotatably connected to the bottom of the moving plate 65. A guide rod 62 is fixedly connected to the top of the asphalt tank 1 near the double-acting screw 64. A gear 66 is fixedly connected to the outer side of the bottom of the double-acting screw 64. Gear 61 and gear 66 are meshed together.

[0022] By adopting the above technical solution, when the rotating column 53 rotates, it drives the first gear 61 to rotate. The first gear 61 meshes with the second gear 66, which in turn drives the bidirectional lead screw 64 to rotate. The guide rod 62 guides the movement of the moving plate 65, thereby driving the moving plate 65 to move vertically back and forth along the outside of the bidirectional lead screw 64. This, in turn, drives the rotating rod 3 and the temperature measuring rod 4 to move vertically back and forth, thereby detecting the temperature of different layers of asphalt inside the asphalt tank 1.

[0023] A keyway 8 is provided in the middle of the rotating column 53, and a spline 7 is fixedly connected to the side of the rotating rod 3. The spline 7 is slidably engaged in the keyway 8.

[0024] By adopting the above technical solution, through the cooperation between the spline 7 and the keyway 8, the rotating rod 3 can move vertically while rotating with the rotating column 53.

[0025] A U-shaped plate 13 is fixedly connected to the top of the asphalt tank 1 and to the outside of the bottom of the double-ended screw 64. A top plate 63 is fixedly connected to the top of the guide rod 62. The top of the double-ended screw 64 is rotatably connected to the top plate 63.

[0026] By adopting the above technical solution, and by setting the U-shaped plate 13 and the top plate 63, it is convenient to limit the movement of the moving plate 65, so that the moving direction of the moving plate 65 changes after contacting the U-shaped plate 13 or the top plate 63.

[0027] A material reducing pipe 10 communicating with the inside of the asphalt tank 1 is fixedly connected to one side of the top of the tank lid 2, and a discharge pipe 12 communicating with the inside of the asphalt tank 1 is fixedly connected to one side of the bottom of the asphalt tank 1.

[0028] By adopting the above technical solution, and by setting up the material reduction pipe 10 and the discharge pipe 12, it is convenient to inject and discharge asphalt into the asphalt tank 1.

[0029] A stirring blade 9 is fixedly connected to the bottom of the temperature measuring rod 4.

[0030] By adopting the above technical solution, and by setting up the stirring blade 9, when the temperature measuring rod 4 rotates, it drives the stirring blade 9 to rotate, thereby stirring the asphalt inside the asphalt tank 1, accelerating the heat transfer, and ensuring temperature uniformity.

[0031] Working principle: When measuring the temperature of special asphalt, the servo motor 51 drives the drive wheel 52 to rotate. The drive wheel 52 meshes with the driven wheel 54, and the spline 7 and keyway 8 work together to drive the rotating column 53 and rotating rod 3 to rotate, thereby driving the temperature measuring rod 4 to rotate, and detecting the temperature in different areas inside the asphalt tank 1.

[0032] When the rotating column 53 rotates, it drives the first gear 61 to rotate. The first gear 61 meshes with the second gear 66, which in turn drives the double-acting screw 64 to rotate. The guide rod 62 guides the movement of the moving plate 65, thereby causing the moving plate 65 to move vertically back and forth along the outside of the double-acting screw 64. This, in turn, causes the rotating rod 3 and the temperature measuring rod 4 to move vertically back and forth, thus detecting the temperature of the asphalt in different layers inside the asphalt tank 1. This allows for temperature detection of the asphalt in various areas inside the asphalt tank 1.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
