Description

Technical Field

[0001] The invention belongs to the technical field of road material recycling, and in particular relates to a multi-component blended recycled asphalt preparation device. Background Art

[0002] During the use of asphalt, due to the long-term effects of sunlight, air and water, as well as the physical and chemical effects between asphalt and mineral materials, asphalt molecules will undergo oxidation and polymerization, turning low molecular compounds into higher molecular compounds, resulting in deterioration of road performance. This phenomenon is usually called "aging". After asphalt ages, the chemical composition changes and the properties also change, which is manifested in reduced penetration, reduced ductility, increased softening point, increased absolute viscosity, and reduced brittle point. In order to restore the performance of the road surface and maintain a certain level of road service, maintenance measures must be taken for the old asphalt pavement. In the reconstruction of old roads, asphalt recycling technology can effectively utilize waste pavement materials, reduce production costs, improve efficiency, and is also conducive to environmental protection and emission reduction.

[0017] like Figures 1 to 6 As shown, a multi-component blended recycled asphalt preparation device of the present invention includes a crushing mechanism 1, a de-impurity section 2 and a stirring section 3. The crushing mechanism 1 pours the crushed asphalt into the de-impurity section 2, and the de-impurity section 2 is used to remove fine impurities and dust adhering to the asphalt. The de-impurity section 2 includes: a connecting shell 210, a first motor 212, a first connecting shaft, a wind driving section 215, a cam 216, a bump 217, a connecting plate 218, a filter plate 221, a coarse impurity discharge port 211, a connecting rod 220, a spring 219 and a dust outlet 214. The upper end of the connecting shell 210 is connected to the crushing mechanism 1, and the upper and lower ends of the connecting shell 210 are open. A baffle 4 is connected to one side of the upper part of the connecting shell 210, and the baffle 4 prevents the asphalt from falling directly into the stirring section 3. The lower end of the connecting shell 210 is connected to the stirring part 3 , and the impurity discharge port 211 is located at the lower end of the connecting shell 210 . One end of the impurity discharge port 211 is obliquely arranged to facilitate the discharge of impurities.

[0018] The side of the first motor 212 is fixedly connected to the upper part of the coarse and impurity discharge port 211, and the output shaft of the first motor 212 passes through the connection shell 210 and is connected to the connection cam 216, so that the first motor 212 drives the cam 216 to rotate. One end of the connecting rod 220 is fixedly connected to the coarse and impurity discharge port 211, and the other end of the connecting rod 220 passes through the connecting plate 218 and is slidably connected to the connecting plate 218, so that the connecting plate 218 can only slide vertically. The protrusion 217 is located at the lower side of the connecting plate 218, and the protrusion 217 corresponds to the cam 216. The connecting rod 220 passes through the spring 219, and the spring 219 is located between the coarse and impurity discharge port 211 and the connecting plate 218, and the spring 219 plays a role in resetting. One side of the connecting plate 218 is fixedly connected to the filter plate 221, and the side of the filter plate 221 is slidably connected to the connection shell 210, and the filter plate 221 is inclined. The upper part of the stirring part 3 is provided with an inlet 5, so that the asphalt falls into the inlet 5. The wind driving unit 215 is located at the side of the connecting shell 210, the output shaft of the first motor 212 is connected to the first pulley 213, and a belt 2157 is connected between the first pulley 213 and the wind driving unit 215 to operate the wind driving unit 215.

[0019] The working principle of the above scheme is as follows: the recycled asphalt is poured into the crushing mechanism 1 to crush the asphalt into blocks, and the asphalt falls onto the filter plate 221. The first motor 212 is started to rotate the cam 216, and the cam 216 contacts the protrusion 217 so that the protrusion 217 drives the connecting plate 218 to move upward, and the connecting plate 218 drives the filter plate 221 to move upward. When the cam 216 no longer contacts the protrusion 217, the spring 219 moves the connecting plate 218 and the filter plate 221 downward, and the cam 216 reciprocates to cause the filter plate 221 to shake. While the filter plate 221 shakes to move the asphalt toward the inlet 5, impurities are shaken into the coarse impurity discharge port 211, and the dust generated by the shaking of the filter plate 221 is blown to the dust outlet 214 by the wind driving unit 215. At this time, the asphalt is driven into the inlet 5 by the filter plate 221 and falls into the stirring part 3.

[0020] The beneficial effects of the above scheme are as follows: the asphalt is broken into blocks by the crushing mechanism 1, and the block asphalt falls into the impurity removal section 2 and the solid impurities and dust on the asphalt are removed by the impurity removal section 2. The asphalt then falls into the stirring section 3 and is melted and stirred evenly by the stirring section 3 before being discharged; the filter plate 221 is shaken by the cam 216 to shake fine impurities into the coarse impurity discharge port 211, and the asphalt is shaken by the filter plate 221 to shake out the dust adhered to the asphalt and blow out the dust by driving the wind drive section 215 through the first motor 212.

A belt 2157 is connected between the first pulley 213 and the second pulley 2151, and the output shaft of the first motor 212 passes through the third pulley 2154, and the third pulley 2154 is coaxially arranged with the first pulley 213. The fourth pulley 2155 and the fifth pulley 2156 are coaxially arranged, and the fourth pulley 2155 is connected to the rotating shaft 2153, and the rotating shaft 2153 passes through the connecting shell 210 and is connected to the fan blade 2152. A belt 2157 is connected between the third pulley 2154 and the fourth pulley 2155, and the third pulley 2154 drives the fourth pulley 2155 and the fifth pulley 2156 to rotate. The sixth pulley 2158 is arranged corresponding to the fifth pulley 2156 and driven by the belt 2157, and the fifth pulley 2156 drives the sixth pulley 2158 to rotate. The sixth pulley 2158 is connected to a rotating shaft 2153, and the rotating shaft 2153 passes through the connecting shell 210 and is fixedly connected to the fan blade 2152. The connecting shell 210 is internally connected with an air guide groove 12, and the wind direction is more stable through the air guide groove 12. The air guide groove 12 is located outside the fan blade 2152.

[0022] The working principle of the above scheme is as follows: when the first motor 212 rotates, it drives the first pulley 213 to rotate, and the first pulley 213 drives the second pulley 2151 and the fan blade 2152 to rotate through the belt 2157. When the first motor 212 rotates, it drives the third pulley 2154 to rotate, and the third pulley 2154 drives the fourth pulley 2155 and the fifth pulley 2156 to rotate through the belt 2157. At this time, the rotating shaft 2153 and the fan blade 2152 rotate, and the fifth pulley 2156 drives the sixth pulley 2158 and the fan blade 2152 to rotate.

[0023] The above solution has the beneficial effect that the first motor 212 drives the plurality of fan blades 2152 to rotate so as to blow dust out of the connecting shell 210, thereby reducing energy costs and equipment costs.

The upper side of the stirring barrel 31 is provided with an input port 11 for inputting asphalt regeneration agent. A push plate 7 is slidably connected in the discharge port 32 to prevent asphalt leakage. A screw rod 6 is rotatably connected to one side of the push plate 7. The screw rod 6 passes through the discharge port 32 and is threadedly connected to the discharge port 32. The lower side of the discharge port 32 is connected to a push groove 10, and the asphalt after stirring and heating enters the push groove 10 through the discharge port 32.

The asphalt is pushed out by the electric cylinder 8 to prevent the problem that the asphalt is difficult to discharge due to its strong viscosity.

[0025] The working principle of the above scheme is as follows: the asphalt is melted by the heating plate 33, and the asphalt regeneration agent is put into the mixing barrel 31. The second motor 36 drives the stirring rod 35 to mix the asphalt and the put asphalt regeneration agent. The mixed asphalt is discharged into the push groove 10 through the discharge port 32.
