Description

Technical Field

[0001] This application relates to the technical field of asphalt production, and in particular to a high-efficiency mixing device for asphalt production. Background Technology

[0002] Asphalt is a complex, dark brown mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid and serves as a waterproof, moisture-proof, and corrosion-resistant organic binder. It primarily exists in the form of tar or asphalt, has a black surface, and is soluble in carbon disulfide. Temperature significantly affects the fluidity and viscosity of asphalt, thus influencing the mixing effect. Different types of asphalt and their mixtures require different mixing temperatures; for example, the mixing temperature for ordinary hot-mix asphalt mixtures is generally between 150℃ and 170℃.

[0003] A search revealed Chinese Patent Publication No. CN 211837368 U, which discloses a high-efficiency mixing device for asphalt production. The device includes a housing, with a mounting shell fixedly installed at the top of the housing, its lower end extending through. A mounting frame is fixedly installed at the top of the housing, and a motor is fixedly installed at the top of the mounting frame. The motor's output shaft is connected to a drive shaft. The lower end of the drive shaft passes sequentially through the mounting frame and the housing, extending into the mounting shell. Two connecting plates are symmetrically fixedly installed at the left and right ends of the drive shaft. A stirring shaft is rotatably mounted on the lower ends of both connecting plates via bearings. The lower ends of both stirring shafts pass through the housing and extend into the housing. Multiple stirring rods are symmetrically and equidistantly fixedly installed at the left and right ends of the two stirring shafts. This invention offers good mixing effect, high efficiency, high automation, simple operation, and high practicality.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the temperature is difficult to control during mixing; if the temperature is too high, the asphalt is prone to aging and deterioration, affecting the performance of the asphalt mixture; if the temperature is too low, the asphalt has high viscosity and is difficult to disperse evenly in the aggregate, resulting in a reduction in the asphalt mixing effect and affecting the subsequent use of the asphalt.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a high-efficiency mixing device for asphalt production. For example... Figure 1As shown, the system includes a base plate 1. A bottom support rod 15 is fixedly installed at one end of the upper surface of the base plate 1. A bottom ring frame 14 is fixedly installed at the top of the bottom support rod 15 via a connecting plate. A mixing tank 2 is fixedly installed on the inner wall of the bottom ring frame 14. A fixing frame 10 is fixedly installed at the top of the inner wall of the mixing tank 2. A motor 9 is fixedly installed at the top of the inner wall of the fixing frame 10. A stirring shaft 11 is fixedly installed on the output shaft at the bottom of the motor 9. A stirring auxiliary rod 12 is fixedly installed on the outer side of the stirring shaft 11 via a horizontal shaft. The edge of the stirring auxiliary rod 12 slides in contact with the inner wall of the mixing tank 2. The multiple sets of stirring auxiliary rods 12 make the asphalt inside the mixing tank 2 more uniformly mixed, preventing the asphalt from clumping. The bottom of the stirring shaft 11 is located in the middle of the mixing tank 2.

[0024] Please see Figure 4 A temperature sensing tube 20 is fixedly installed on one side of the inner wall of the mixing tank 2. The temperature sensing tube 20 is filled with mercury temperature sensing liquid. A sliding block plate is installed above the mercury temperature sensing liquid. The block plate slides in contact with the bottom of the moving rod 8. The mercury temperature sensing liquid inside the temperature sensing tube 20 rises and falls with the increase and decrease of temperature. When the block plate rises and falls, it drives the moving rod 8 to move. At the same time, the moving rod 8 drives the horizontal plate 6 above to rise and fall.

[0025] Please refer to it again. Figure 4 A moving rod 8 is interlocked at the middle of the top of the temperature sensing tube 20. A horizontal plate 6 is fixedly installed at the top of the moving rod 8. A fixed vertical plate 7 is slidably sleeved in the middle of the horizontal plate 6. The bottom of the fixed vertical plate 7 is fixedly installed at the top of the fixed ring 13. A spring is fixedly installed at the bottom of the sliding groove in the middle of the fixed vertical plate 7. The top of the spring is fixedly connected to the bottom of the horizontal plate 6. The fixed vertical plate 7 limits the movement position of the horizontal plate 6 and resets the horizontal plate 6 in time after movement through the spring in the middle.

[0026] Please see Figure 1 and Figure 2The end of the horizontal plate 6 away from the moving rod 8 is connected to a vertical rod 5 via a rotating rod. The bottom of the vertical rod 5 passes through the top of the power box 3. The two ends of one side of the power box 3 are fixed to the outside of the fixing ring 13. There are two fixing rings 13, which are symmetrically arranged at both ends of the outside of the mixing tank 2. By setting two fixing rings 13, the installation of the power box 3 on one side is more stable. The top of the outside of the fixing ring 13 is fixedly provided with a side connecting rod 16, which supports the side of the fixing ring 13. The bottom of the connecting rod is fixedly provided to the middle of the outside of the bottom ring frame 14. The inner wall of the fixing ring 13 is fixedly sleeved. At both ends of the mixing tank 2, a triangular slider 4 is fixedly installed at the bottom of the vertical rod 5. An elastic switch 21 is slidably installed on the inclined surface of one side of the bottom of the triangular slider 4. A spring is installed on the inner side of the elastic switch 21. The moving rod 8 on the left side of the elastic switch 21 slides laterally with the middle of the right side of the power block 22. The right side of the elastic switch 21 is rounded. The elastic switch 21 moves left and right under the action of the triangular slider 4 to realize the opening and closing of the power block 22. The rounded corner of the elastic switch 21 makes the connection with the side of the triangular slider 4 smoother. One end of the elastic switch 21 is fixedly installed in the middle of one side of the power block 22.

[0027] Please see Figure 2 and Figure 3 A power cord 19 is connected to the left side of the power block 22. The end of the power cord 19 away from the power block 22 passes through one side of the power box 3 and connects to one side of the heating ring 17. The power cord 19 connects the power block 22 and the heating ring 17 into a whole. The power block 22 provides power support to the heating ring 17. The middle part of the heating ring 17 is fixedly sleeved on the outside of the mixing tank 2. There are three heating rings 17. The three heating rings 17 are evenly arranged on the outside of the mixing tank 2. The three heating rings 17 are fixedly connected to each other by a fixing rod 18. The even placement of the three sets of heating rings 17 makes the internal heating of the mixing tank 2 more uniform. One side of the power block 22 is fixedly set on one side of the inner wall of the power box 3.

[0028] The implementation principle of the high-efficiency mixing device for asphalt production in this embodiment is as follows: The asphalt to be mixed is poured into the mixing tank 2 through the feed inlet at the top. The motor 9 drives the stirring shaft 11 to rotate, so that the asphalt inside is fully mixed. At the same time, the elastic switch 21 is turned on so that the power block 22 provides power to the heating ring 17. The heating ring 17 heats the asphalt inside the mixing tank 2, making the asphalt mixture more uniform. When the temperature of the asphalt inside the mixing tank 2 is too high, the mercury temperature sensing liquid inside the temperature sensing tube 20 moves upward. At the same time, the moving rod 8 drives the horizontal plate 6 to move upward. The horizontal plate 6 drives the triangular slider 4 to slide inside the power box 3 through the vertical rod 5. When the triangular slider 4 moves, it contacts the elastic switch 21, and the elastic switch 21 turns off the power block 22, so that the heating ring 17 stops heating in time, avoiding the internal temperature from being too high, avoiding the aging and deterioration of the asphalt, ensuring the performance of the asphalt mixture, and making the asphalt mixture more fully mixed.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
