Abstract
Description
Technical Field
[0001] This invention relates to the field of asphalt processing equipment technology, and specifically to a modified asphalt cooling device. Background Technology
[0002] Modified asphalt (AR) is a new type of high-quality composite material. It is produced through the combined action of heavy-duty asphalt, waste tire rubber powder, and additives. The rubber powder absorbs resins, hydrocarbons, and other organic matter from the asphalt, undergoing a series of physical and chemical changes that cause the rubber powder to become wetted, swell, increase viscosity, and raise the softening point. It also combines the viscosity, toughness, and elasticity of both rubber and asphalt, thus improving the road performance of the rubberized asphalt. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material, mainly used in coatings, plastics, rubber industries, and road paving. Asphalt is flammable and irritating; it ignites when exposed to open flames or high heat, releasing toxic and irritating fumes during combustion, polluting the environment.

Multiple horizontally arranged mixing shafts 2 are located inside the mixing tank 1, each with a mixing rod. Multiple vertically moving mixing mechanisms 7 are also located inside the mixing tank 1. A drive mechanism 3 is located on one side of the mixing tank 1 to simultaneously drive the mixing shafts 2 and the mixing mechanisms 7. The drive mechanism 3 simultaneously drives the mixing mechanism 7 and the mixing shaft 2 to improve the mixing effect of asphalt. A spray pipe 5 is provided at the center of the mixing tank 1. The surface of the spray pipe 5 is provided with several spray holes 503. The water tank 13 is connected to the spray pipe 5 through the water pipe 4. A check valve 6 is provided at one end of the spray pipe 5 connected to the water pipe 4. Water can only flow from the water pipe 4 into the spray pipe 5 in one direction. The other end of the spray pipe 5 is connected to a piston rod 501 that can move up and down. A filter plate 12 is provided at the bottom of the mixing tank 1. The filter plate 12 only allows water to pass through. The filtered water flows out from the outlet 103.
[0026] like Figure 2 As shown, the drive mechanism 3 includes a drive motor 31, which can rotate in both directions. During operation, the drive motor 31 rotates in both directions intermittently. One end of each stirring shaft 2 is fixedly connected to a pulley 32, and a belt line 33 is connected between adjacent pulleys 32. The shaft of the drive motor 31 is connected to one of the pulleys 32, and the drive motor 31 drives multiple stirring shafts 2 to rotate simultaneously.
[0027] A rotating rod 9 is connected inside the mixing tank 1. One end of the rotating rod 9 is connected to a first gear 901. A second gear 34 is connected to a pulley 32. The first gear 901 and the second gear 34 mesh. A crankshaft 11 is provided on the rotating rod 9. One end of the piston rod 501 is rotatably connected to a connecting rod 504. The connecting rod 504 is rotatably connected to the crankshaft 11. A sealing seat 502 is provided at one end of the piston rod 501 inside the spray pipe 5. When the rotating rod 9 rotates, it drives the piston rod 501 to move up and down back and forth, thereby drawing water from the water tank 13 into the spray pipe 5 and then spraying it out from the spray pipe 5.
[0028] like Figures 3-4As shown, the stirring mechanism 7 includes a vertically arranged lead screw 701 and a guide rod 702. A lifting seat 8 is threaded onto the lead screw 701 and slidably connected to the guide rod 702. A stirring blade 805 capable of circular motion is connected to the lifting seat 8.
