Abstract
Description
Technical Field
[0001] This utility model belongs to the field of asphalt production technology, specifically a high-speed shear mixing device for emulsified asphalt production. Background Technology
[0002] Emulsified asphalt is a water-in-oil emulsion material formed by dispersing viscous asphalt, petroleum asphalt, or coal tar pitch into tiny particles through thermal melting and mechanical action, and stably suspending them in an aqueous solution containing an emulsifier.
[0003] In existing technology, CN217795625U describes a mixing-type shearing device for modified asphalt, comprising a shearing assembly, a heating jacket, and an asphalt placement container. The shearing assembly includes a support plate, a telescopic rod, a lifting device, a drive motor, and a shear head. The lifting device is connected to the support plate. One end of the support plate is connected to the telescopic rod, and the other end is connected to the drive motor via a connecting plate. The output end of the drive motor is connected to the shear head. The asphalt placement container is placed inside the heating jacket and below the shear head. By setting the telescopic rod and the lifting device, the height of the shear head can be adjusted as needed, thereby achieving the mixing of different amounts of asphalt and producing a sufficient quantity of asphalt in a single operation. This avoids data instability caused by repeated small-scale trials and reduces the impact of repeated experimental operations on asphalt quality, improving work efficiency and data accuracy.
[0004] Existing high-speed shear mixing devices for emulsified asphalt production cause the asphalt to shake during operation. When the shaking is too violent, the asphalt will splash. Therefore, a high-speed shear mixing device for emulsified asphalt production is proposed to address the above problem. Utility Model Content

[0025] Specific implementation examples are given below.
[0026] Please see Figures 1-4 This utility model provides a high-speed shear mixing device for emulsified asphalt production, including a mounting base 5; an electric push rod 6 is mounted on the inner wall of the mounting base 5; an auxiliary frame 7 is fixedly connected to the output end of the electric push rod 6; a connecting rod 14 is fixedly connected to the bottom of the auxiliary frame 7; a sealing cover 15 is fixedly connected to the bottom of the connecting rod 14; a damping rod 17 is fixedly connected to the inner wall of the sealing cover 15; a sealing ring 16 is slidably connected to the outer wall of the damping rod 17; a return spring 18 is fixedly connected to the sealing ring 16 through the sealing cover 15; a trigger rod 19 is fixedly connected to the top of the sealing ring 16 through the sealing cover 15; and a return spring 18 is fixedly connected to the top of the sealing cover 15. A trigger frame 20 is connected; a push switch 21 is installed at the bottom of the trigger frame 20; the push switch 21 is electrically connected to the electric push rod 6; during operation, the electric push rod 6 can drive the auxiliary frame 7 and the sealing cover 15 to descend as a whole. At the same time, when the sealing ring 16 is in contact with the mixing tank body 4, the sealing ring 16 will slide on the outer wall of the damping rod 17, and the return spring 18 will be in a compressed state, making the sealing ring 16 and the mixing tank body 4 fit more tightly. During this process, the trigger rod 19 will slide inside the sealing cover 15 and then rise to trigger the push switch 21. At this time, the push switch 21 will start and then turn off the electric push rod 6.
[0027] Furthermore, such as Figure 1 and Figure 4 As shown, a servo motor 8 is mounted on the top of the auxiliary frame 7; a motor bevel gear 11 is fixedly connected to the output end of the servo motor 8; an outer rod 10 is rotatably connected to the inner wall of the connecting rod 14; an inner rod 9 is rotatably connected to the inner wall of the outer rod 10; a cutting blade 24 is fixedly connected to the bottom of the inner rod 9; a bottom bevel gear 13 is fixedly connected to the outer wall of the outer rod 10; the bottom bevel gear 13 meshes with the bottom of the motor bevel gear 11; a top bevel gear 12 is fixedly connected to the top of the inner rod 9; the top bevel gear 12 meshes with the top of the motor bevel gear 11; a stirring body 22 is fixedly connected to the bottom of the outer rod 10; a stirring block 23 is fixedly connected to the outer wall of the stirring body 22; a device base 1 is fixedly connected to the bottom of the mounting base 5; a device stand 3 is fixedly connected to the bottom of the device base 1; a stirring tank base 2 is fixedly connected to the top of the device base 1; a stirring tank body 4 is slidably connected to the top of the stirring tank base 2. During operation, after starting the servo motor 8, the motor bevel gear 11 can rotate, which in turn drives the top bevel gear 12 and bottom bevel gear 13 meshing with it to rotate in opposite directions. Then, the internal rod 9 and external rod 10, which rotate relative to each other, drive the stirring block 23 and the cutting blade 24 to rotate in opposite directions at high speed, thereby achieving the purpose of stirring while simultaneously performing a shearing operation.
[0028] Working principle: The electric push rod 6 can drive the auxiliary frame 7 and the sealing cover 15 to descend as a whole. At the same time, when the sealing ring 16 is in contact with the mixing tank body 4, the sealing ring 16 will slide on the outer wall of the damping rod 17. Meanwhile, the return spring 18 is in a compressed state, making the sealing ring 16 and the mixing tank body 4 fit more tightly. During this process, the trigger rod 19 will slide inside the sealing cover 15 and then rise to trigger the press switch 21. At this time, the press switch 21 will start and then turn off the electric push rod 6. After the servo motor 8 is started, the motor bevel gear 11 will rotate, and at the same time, it will drive the top bevel gear 12 and the bottom bevel gear 13 that mesh with it to rotate in opposite directions. The internal rod 9 and the external rod 10 rotate in opposite directions to drive the mixing block 23 and the cutting blade 24 to rotate in opposite directions at high speed, thereby achieving the purpose of mixing and synchronous shearing operation.
