Figures 1-3 The application will be described in detail as follows:

[0024] A feeding hopper 1 and a mixing cylinder 2, the feeding hopper 1 is communicated at the top of the mixing cylinder 2, the mixing cylinder 2 has a plurality of ball cavities which are connected to each other, and the bottom end of the mixing cylinder 2 is communicated with a discharge pipe 3, and a discharge valve is installed at the lower end of the discharge pipe 3;

[0025] A mixing mechanism 4 is used for mixing the additives, the mixing mechanism 4 comprises a mounting plate 401 fixedly arranged at the upper end of the feeding hopper 1, a driving motor 402 is mounted at the top of the mounting plate 401, a driving rod 403 is connected to the output shaft of the driving motor 402 and penetrates through the mounting plate 401, a rotating disc 404 is fixedly arranged at the section of the driving rod 403 inside the mixing cylinder 2, the rotating disc 404 is located at the upper side of each ball cavity and does not abut against the cavity wall of the ball cavity;

[0026] A stirring part 5 is arranged at the upper side of the driving rod 403 and is used for stirring the additives entering the feeding hopper 1.

[0027] Working process

[0028] First step, feeding: a plurality of additives are sent to the inside of the feeding hopper 1 through a screw conveying device or a conveying belt;

[0029] Second step, preliminary stirring: the driving motor 402 works to drive the stirring part 5 to preliminarily stir the additives entering the feeding hopper 1 so as to uniformly mix the additives;

[0030] Third step, centrifugal dispersion: the additives fall on the rotating disc 404 above, the rotating disc 404 rotates under the action of the driving motor 402, and the additives are thrown to the inner wall of the mixing cylinder 2 under the action of centrifugal force, and the additives thrown to the inner wall of the mixing cylinder 2 fall on the rotating disc 404 below again, and the process is repeated for several times to realize more uniform mixing;

[0031] Fourth step, discharging: the mixed additives are discharged outward from the discharge pipe 3 to realize continuous operation.

[0032] The continuous dispersion mixing device for additive in modified asphalt production is characterized in that the mixing barrel 2 ball cavity is designed in cooperation with the mixing mechanism 4, and the centrifugal force generated by the rotation of the rotating disc 404 is used to throw the additive to the inner wall of the mixing barrel 2, and then the repeated mixing is realized through the ball cavity structure, thereby enhancing the mixing effect, realizing the continuous dispersion mixing of the additive, solving the problem that the traditional intermittent stirring kettle cannot continuously work, and improving the production efficiency.

[0033] As shown in the drawings, Figure 3 In some embodiments, the top of the rotating disc 404 is a spherical structure, and more specifically, the spherical structure makes the material more easily slide off the surface of the rotating disc 404 under the action of centrifugal force during rotation, reducing the possibility of material adhesion and accumulation. This self-cleaning effect helps to keep the surface of the rotating disc 404 clean and ensures that each mixing can achieve the best effect.

[0034] As shown in the drawings, Figure 3 In some embodiments, the stirring piece 5 includes a fixed disc 501 fixed on the surface of the driving rod 403, and the edge side annular array of the fixed disc 501 is hinged with a raking plate 502, and more specifically, the stirring piece 5 includes a fixed disc 501 fixed on the surface of the driving rod 403, and the edge side annular array of the fixed disc 501 is hinged with a raking plate 502, and the rotation and swing of the raking plate 502 helps to break the agglomeration between the materials and promote the flow of the materials in the feeding hopper 1, avoiding material deposition and caking.

[0035] As shown in the drawings, Figure 3 In some embodiments, the inner wall of the feeding hopper 1 is fixed with annular protrusions 102 at equal intervals, the cross section of the annular protrusions 102 is arc-shaped, and the bottom side of the raking plate 502 is constructed with arc-shaped notches 5021 matched with the annular protrusions 102 at equal intervals, and more specifically, the existence of the annular protrusions 102 slows down the sliding speed of the additive in the feeding hopper 1, prolongs the residence time of the material in the stirring area, and helps to improve the stirring effect, and when the raking plate 502 rotates, the annular protrusions 102 will generate additional shear force and friction force on the material, enhancing the stirring intensity and promoting the mixing between the materials, and the arc-shaped notches 5021 on the bottom side of the raking plate 502 are matched with the annular protrusions 102, ensuring that the raking plate 502 can smoothly pass through the annular protrusions 102 during rotation, while maintaining effective stirring of the material.

[0036] As shown in the drawings, Figure 1As shown, in some embodiments, the four sides of the upper port of the feed hopper 1 are connected outwardly to a guide hopper 101, and the guide hopper 101 is arranged to be inclined upward. More specifically, the main function of the guide hopper 101 is to guide the additives from the external conveying equipment (conveyor belt or screw conveyor) to smoothly enter the feed hopper 1, ensuring the smoothness and continuity of the material flow. The upward angle is conducive to the natural sliding of the material, avoiding the accumulation and blockage of the material at the entrance of the feed hopper 1.

[0037] like Figure 1 As shown, in some embodiments, a support frame 6 is further included, and the support frame 6 is used to support the feed hopper 1. The support frame 6 includes support legs 601 fixed at the four corners of the bottom surface of the feed hopper 1, and a load-bearing plate 602 is connected between the bottoms of the support legs 601 on the same side, and a reinforcing rod 603 is connected between the middle part of the support leg 601 and the mixing barrel 2. More specifically, the support legs 601 are fixed at the four corners of the bottom surface of the feed hopper 1, providing stable support for the feed hopper 1 and ensuring the stability of the feed hopper 1 during operation.
