[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-4 As shown, a foamed asphalt spraying device comprises:

[0026] A body 1, on which a foaming water nozzle 2, an asphalt nozzle 3 and an air nozzle 5 are arranged;

[0027] A first dispersing disc 7 is arranged in a trumpet shape, and a first dispersing tooth 72 is arranged in an array on the first dispersing disc 7;

[0028] The material distribution mechanism 8 comprises a second dispersion disc 84, which is arranged in an umbrella shape and has second dispersion teeth 83 arranged in an array on the second dispersion disc 84;

[0029] The second dispersing disc 84 is driven to rotate so that the first dispersing teeth 72 and the second dispersing teeth 83 which are arranged offset from each other rotate relative to each other.

[0030] Specifically, foaming water, asphalt and air are sprayed into the main body 1 simultaneously through the foaming water nozzle 2, the asphalt nozzle 3 and the air nozzle 5. After entering the main body 1, the foaming water, asphalt and air are located between the first dispersing disk 7 and the second dispersing disk 84. The second dispersing disk 84 is driven to rotate, so that the second dispersing disk 84 rotates relative to the first dispersing disk 7, thereby mixing the foaming water, asphalt and air. The foamed asphalt is discharged through the discharge port 4, which can make the foaming water, asphalt and air fully contact and foam, so that the asphalt foams more evenly.

[0031] Since the first dispersion disk 7 is arranged in a trumpet shape and the second dispersion disk 84 is arranged in an umbrella shape, the trumpet surface of the first dispersion disk 7 close to the second dispersion disk 84 is arranged parallel to the umbrella surface of the second dispersion disk 84 close to the first dispersion disk 7, and the nozzle opening of the asphalt nozzle 3 is located in the port at the top of the first dispersion disk 7, so when the asphalt nozzle 3 sprays asphalt, the asphalt first collides with the top of the second dispersion disk 84, thereby slowing down the sprayed asphalt. Since the umbrella-shaped top of the second dispersion disk 84 is conical, when the asphalt collides with the top of the second dispersion disk 84, the conical top of the second dispersion disk 84 disperses the asphalt and makes the asphalt flow along the umbrella surface of the second dispersion disk 84, so that the asphalt is fully in contact with the air and the foaming water, thereby improving the foaming effect.

[0032] Since the first dispersing teeth 72 are arranged on the trumpet surface of the first dispersing disk 7, and the second dispersing teeth 83 are arranged on the umbrella surface of the second dispersing disk 84, and the two are staggered, when the second dispersing disk 84 is driven to rotate, the first dispersing teeth 72 and the second dispersing teeth 83 rotate relative to each other, and the shear force generated by the meshing of the first dispersing teeth 72 and the second dispersing teeth 83 can achieve high dispersion of foaming water, asphalt and air, so that as the second dispersing teeth 83 rotate, the foaming water, asphalt and air are highly dispersed, and the foaming water, asphalt and air are fully mixed and contacted while being highly dispersed, so that the asphalt foaming is more uniform and the foaming effect is better.

[0033] In the above technology, foaming water, asphalt and air are sprayed into the body 1 through the foaming water nozzle 2, the asphalt nozzle 3 and the air nozzle 5 at the same time. After the foaming water, asphalt and air enter the body 1, they are all located between the first dispersion disk 7 and the second dispersion disk 84, driving the second dispersion disk 84 to rotate, so that the second dispersion disk 84 and the first dispersion disk 7 rotate relative to each other. When the asphalt nozzle 3 sprays asphalt, the asphalt first collides with the top of the second dispersion disk 84, thereby slowing down the sprayed asphalt. Since the umbrella-shaped top of the second dispersion disk 84 is conical, when the asphalt collides with the top of the second dispersion disk 84, the conical top of the second dispersion disk 84 disperses the asphalt and makes the asphalt flow along the umbrella surface of the second dispersion disk 84, thereby making the asphalt It is in full contact with air and foaming water to improve the foaming effect. When the second dispersing disk 84 is driven to rotate, the first dispersing teeth 72 and the second dispersing teeth 83 rotate relative to each other. The shear force generated by the meshing of the first dispersing teeth 72 and the second dispersing teeth 83 can achieve high dispersion of foaming water, asphalt and air. Therefore, as the second dispersing teeth 83 rotate, high dispersion of foaming water, asphalt and air is achieved, and full mixing and contact of foaming water, asphalt and air is also achieved, so that the asphalt foaming is more uniform and the foaming effect is better. By setting the first dispersing disk 7 and the second dispersing disk 84, high dispersion and mixing of asphalt, foaming water and air can be achieved, the contact is more sufficient, the mixing is more uniform, the foaming effect is better, and the structure is simple and easy to manufacture.

[0034] As a further embodiment of the present invention, a first sleeve 71 is symmetrically arranged on the first dispersion disk 7 , and the nozzle of the foaming water nozzle 2 is located in the first sleeve 71 .

[0035] Specifically, the foaming water nozzle 2 introduces foaming water between the first dispersion disk 7 and the second dispersion disk 84 through the first sleeve 71, and contacts the asphalt dispersed through the top of the second dispersion disk 84. As the second dispersion disk 84 rotates, the foaming water can fully contact the dispersed asphalt, and the contact is more uniform, thereby improving the foaming effect.

[0036] As the second dispersing disk 84 rotates, the asphalt and the foaming water are driven to flow downward in a vortex along the umbrella-shaped surface of the second dispersing disk 84 , so that the asphalt is not easy to enter the first sleeve 71 , thereby preventing the asphalt from clogging the foaming water nozzle 2 .

[0037] As a further embodiment of the present invention, the material equalizing mechanism 8 further includes a second sleeve 81 , and the nozzle of the air nozzle 5 is located in the second sleeve 81 .

[0038] Specifically, Figure 3As shown, the top of the second dispersion disc 84 is provided with air outlets 82 in a circumferential array. The air nozzle 5 sprays air into the second sleeve 81, and the air is gathered at the top of the second dispersion disc 84. Since the top of the second dispersion disc 84 is conical, the air is gathered at the top and accelerated, and is discharged through the air outlets 82 at the top of the second dispersion disc 84, and contacts with the asphalt. Since the air outlets 82 are arranged in a circumferential array, the contact between the air and the asphalt is more uniform. At the same time, due to the rotation of the second dispersion disc 84 and the second dispersion teeth 83, the mixing effect of the air, the asphalt and the foaming water is improved, thereby improving the quality of the foamed asphalt.

[0039] Since the air nozzle 5 is arranged in the second sleeve 81, asphalt is prevented from being blocked by the air nozzle 5. Since the air outlet 82 is arranged downward along the top of the second dispersion disk 84, and the flow direction of the asphalt also flows downward along the umbrella vortex of the second dispersion disk 84, the air outlet 82 is not easily blocked by asphalt, which can effectively prevent the occurrence of blockage, make the work smoother, and improve work efficiency.

[0040] As a further embodiment of the present invention, the material balancing mechanism 8 further includes a retaining ring 85 and a driven gear 86 .

[0041] Specifically, it also includes a driving mechanism 6, which includes a motor 62, and the output end of the motor 62 is fixedly connected to a driving gear 63, and the driving gear 63 is meshed and connected with a driven gear 86. The motor 62 installed on the bracket 61 is started to rotate, thereby driving the driving gear 63 to rotate, thereby driving the driven gear 86 to rotate, and thereby driving the second sleeve 81 and the second dispersion disc 84 to rotate. Through the provided clamping ring 85, the bottom of the body 1 is blocked while supporting the second sleeve 81 and the second dispersion disc 84. The second dispersion disc 84 rotates and cooperates with the first dispersion disc 7, so that the foaming water, asphalt and air can be fully contacted for foaming, so that the asphalt foams more evenly, and the foaming effect and the quality of the foamed asphalt are improved.

[0042] Working principle: Foaming water, asphalt and air are sprayed into the body 1 through the foaming water nozzle 2, the asphalt nozzle 3 and the air nozzle 5 at the same time. After the foaming water, asphalt and air enter the body 1, they are all located between the first dispersion disc 7 and the second dispersion disc 84. The motor 62 is started to rotate, thereby driving the driving gear 63 to rotate, thereby driving the driven gear 86 to rotate, thereby driving the second sleeve 81 and the second dispersion disc 84 to rotate, so that the second dispersion disc 84 and the first dispersion disc 7 rotate relative to each other. When the asphalt nozzle 3 sprays asphalt, the asphalt first collides with the top of the second dispersion disc 84, thereby decelerating the sprayed asphalt. Since the umbrella-shaped top of the second dispersion disc 84 is conical, when the asphalt collides with the second dispersion disc 84, the asphalt is decelerated. When the top of the second dispersing disc 84 hits, the conical top of the second dispersing disc 84 disperses the asphalt and makes the asphalt flow along the umbrella surface of the second dispersing disc 84, so that the asphalt is fully in contact with the air and the foaming water, and the foaming effect is improved. When the second dispersing disc 84 is driven to rotate, the first dispersing teeth 72 and the second dispersing teeth 83 rotate relative to each other. The shear force generated by the meshing of the first dispersing teeth 72 and the second dispersing teeth 83 can achieve a high dispersion of the foaming water, asphalt and air. Therefore, as the second dispersing teeth 83 rotate, the foaming water, asphalt and air are highly dispersed, and the foaming water, asphalt and air are fully mixed and contacted, so that the asphalt foaming is more uniform and the foaming effect is better.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
