When the stirring and spraying mechanism 5 rotates, the base asphalt and the modifier are sprayed into the swelling reaction module 2, which is beneficial to the full mixing of the base asphalt and the modifier at different positions.

[0050] The feed module 1 includes a feed hopper 11, a longitudinal feed pipe 12 and a transverse feed pipe 13; the upper and lower ends of the longitudinal feed pipe 12 are connected to the feed hopper 11 and the transverse feed pipe 13, and the transverse feed pipe 13 is sealed and slidable in the stirring and spraying mechanism 5; the circulation tank module 3 is connected to the longitudinal feed pipe 12. The matrix asphalt and modifier can be put into the interior of the present invention through the feed hopper 11. After the control valve on the longitudinal feed pipe 12 is opened, the matrix asphalt and modifier can enter the longitudinal feed pipe 12 through the feed hopper 11 and enter the stirring and spraying mechanism 5 through the transverse feed pipe 13, so as to be transported to the swelling reaction module 2 through the stirring and spraying mechanism 5. A delivery pump can be installed on the transverse feed pipe 13 to facilitate the matrix asphalt and modifier to be sprayed out through the spraying mechanism 5; the control valve on the longitudinal feed pipe 12 is located above the connection between the circulation tank module 3 and the longitudinal feed pipe 12. After adding an appropriate amount of matrix asphalt and modifier, the control valve on the longitudinal feed pipe 12 is closed, so that the matrix asphalt and modifier flow in the circulating channel structure formed by the feed module 1, the stirring and spraying mechanism 5, the swelling reaction module 2 and the circulation tank module 3.

[0051] The stirring and spraying mechanism 5 includes a friction linkage disk 51, a rotating sleeve 52, a sliding rotating tube 53, a stirring rod 54, a reciprocating push-pull assembly 55, a spraying scraper assembly 56 and a grinding roller assembly 57; the rotating sleeve 52 is sealed and rotated at one end of the swelling reaction module 2, and the friction linkage disk 51, which is transmission-connected to the driving mechanism 4, is fixed on the rotating sleeve 52; the middle part of the sliding rotating tube 53 is sealed and slidable in the rotating sleeve 52, and a convex ridge that slides with the guide groove of the sliding rotating tube 53 is provided in the rotating sleeve 52; the sliding rotating tube 53 is inserted into the tube body at one end of the swelling reaction module 2 and surrounds and fixes the grinding roller assembly 57, multiple stirring rods 54 and multiple spraying scraper assemblies 56; the other end of the sliding rotating tube 53 is connected to the reciprocating push-pull assembly 55, and the reciprocating push-pull assembly 55 is transmission-connected to the driving mechanism 4; the transverse feed pipe 13 is sealed and slidable in the sliding rotating tube 53. The matrix asphalt and the modifier can enter the sliding rotating tube 53 through the transverse material delivery pipe 13, and enter the multiple spraying scraper assemblies 56 through the sliding rotating tube 53, so as to enter the swelling reaction module 2 through the multiple spraying scraper assemblies 56 for reaction; after the driving mechanism 4 is started, it can drive the friction linkage disk 51 to rotate, and when the friction linkage disk 51 rotates, it can drive the rotating sleeve 52 to rotate, and when the rotating sleeve 52 rotates, it can drive the sliding rotating tube 53 to rotate around its own axis, and when the sliding rotating tube 53 rotates, it can drive the stirring rod 54, the spraying scraper assembly 56 and the grinding roller assembly 57 to rotate and circle, so that the stirring rod 54 can be used to control the swelling reaction module 2. The raw materials are mixed and stirred. The spray scraper assembly 56 is used to scrape off the raw materials adhering to the inner wall of the swelling reaction module 2 during the mixing of the raw materials. The grinding roller assembly 57 is used to roller-grind the raw materials on the inner wall of the swelling reaction module 2 to improve the fineness of the raw materials, improve the mixing reaction effect, and finally improve the quality of the processed modified asphalt. After the driving mechanism 4 is started, the reciprocating push-pull assembly 55 can also drive the sliding rotating tube 53 to slide reciprocatingly in the horizontal direction on the rotating sleeve 52, thereby driving the stirring rod 54, the spray scraper assembly 56 and the grinding roller assembly 57 to reciprocate in the horizontal direction, so as to mix and stir the raw materials at different positions, which is beneficial to improve the mixing effect.

[0052] The grinding roller assembly 57 includes a roller body, a support shaft and a support plate; two support plates are provided, the two support plates are relatively fixed on the sliding rotating tube 53, the two support plates are connected by a support shaft, the support shaft is connected to the roller body, and the roller body rolls on the inner wall of the circular chamber of the swelling reaction module 2.

When the stirring spraying mechanism 5 rotates faster, the inertia is greater, and the sliding sleeve 56b on the spraying pipe 56a swings outward to a greater extent, so that more spraying ports are opened and the flow speed is faster. At this time, the reset spring 56c is stretched. When the arc scraper 56d swings to contact the inner wall of the swelling reaction module 2, the raw materials adhered to the inner wall of the swelling reaction module 2 can be scraped off, so that the raw material flow effect is better, and the raw materials are prevented from adhering to the inner wall of the swelling reaction module 2 to cause uneven mixing.

[0054] The hanger mechanism 6 includes a hanging horizontal axis 61, a side bracket 62, a base 63 and a hanging seat 64; there are two side brackets 62, the two side brackets 62 are fixedly connected by the hanging horizontal axis 61, and the two side brackets 62 are relatively fixed at both ends of the base 63; there are two hanging seats 64, the two hanging seats 64 are rotatably connected to the hanging horizontal axis 61, and the swelling reaction module 2 and the circulation tank module 3 are fixed on the two hanging seats 64; an irregular gear ring 58 is installed on the outer ring surface of the friction linkage disk 51, and the irregular gear ring 58 is engaged with the arc-shaped rack 59 fixed on the base 63.

When the swelling reaction module 2 drives the hanging seat 64 to swing on the hanging horizontal shaft 61, the pinion 73 meshes with different positions of the large gear 74, thereby driving the pinion 73 to rotate to a certain extent, and finally driving the stirring shaft 71 and the plurality of stirring impellers 72 to mix and stir the raw materials flowing in the circulation tank module 3 to a certain extent, without adding other power, thus saving energy and reducing consumption.
