[0003] The existing technology has the following problems:

[0004] Traditional equipment often uses a single mixing method with a fixed mixing shaft speed. This makes it impossible to adjust the mixing force and range according to the characteristics of high-viscosity asphalt, resulting in uneven emulsification and affecting the quality of asphalt concrete. Utility Model Content

[0005] This invention provides a high-viscosity asphalt emulsification device for asphalt concrete production, in order to solve the problem of poor emulsification effect mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-5 As shown, a high-viscosity asphalt emulsification device for asphalt concrete production includes a mixing tank 1, multiple support legs 2 fixedly connected to the bottom of the mixing tank 1, a cover plate 3 provided on the top of the mixing tank 1, a mixing shaft 4 rotatably connected inside the cover plate 3, multiple mixing rods 5 fixedly connected to the outer periphery of the mixing shaft 4, a discharge pipe 6 fixedly connected to the bottom of the mixing tank 1, an upper and lower mixing mechanism 7 provided on the top of the mixing tank 1, and a metering mechanism 8 fixedly connected to the top of the mixing tank 1.

[0027] The upper and lower stirring mechanism 7 includes a motor base 70, which is fixedly connected to the top of the cover plate 3 on the outside. A first motor 71 is fixedly connected to the top of the motor base 70. A first gear 72 is fixedly connected to the output end of the first motor 71. A transmission cylinder 73 is fixedly connected to the bottom of the first gear 72. Multiple fixed blocks 74 are slidably connected inside the transmission cylinder 73. A second gear 75 is rotatably connected to the bottom of the motor base 70. A reciprocating screw 76 is fixedly connected to the bottom of the second gear 75. A threaded block 77 is threadedly connected to the outer circumference of the reciprocating screw 76. A lifting ring 78 is fixedly connected to the outer side of the threaded block 77. A guide rod 79 is fixedly connected to the bottom of the motor base 70.

[0028] It should be noted that in the upper and lower stirring mechanism 7, after the first motor 71 is started, the first gear 72 at the output end rotates, driving the transmission cylinder 73 to rotate. The fixed block 74 and the stirring shaft 4 rotate accordingly, realizing the rotational stirring of the stirring rod 5. At the same time, the first gear 72 meshes with the second gear 75 and rotates. The second gear 75 drives the reciprocating screw 76 to rotate. The threaded block 77 moves up and down along the guide rod 79 on the reciprocating screw 76. The lifting ring 78 drives the fixed block 74 to move up and down inside the transmission cylinder 73, so that the stirring shaft 4 and the stirring rod 5 move up and down while rotating, forming an upper and lower stirring effect.

[0029] The metering mechanism 8 includes a mounting shell 80, which is fixedly connected to the top of the cover plate 3 on the outside. A second motor 81 is fixedly connected to the outside of the mounting shell 80. A rotating shaft 82 is fixedly connected to the output end of the second motor 81. A cam 83 is fixedly connected to the outer periphery of the rotating shaft 82. A piston plate 84 is slidably connected inside the mounting shell 80. Springs 85 are provided at the four corners of the top of the piston plate 84. An input pipe 86 is fixedly connected to the outside of the mounting shell 80. An output pipe 87 is fixedly connected to the outside of the mounting shell 80.

[0030] It should be noted that the second motor 81 of the metering mechanism 8 drives the rotating shaft 82 and the cam 83 to rotate. The cam 83 periodically squeezes the piston plate 84, causing the piston plate 84 to move downward in the mounting shell 80, stretching the spring 85. The emulsifier or water in the mounting shell 80 is metered out through the output pipe 87. When the cam 83 disengages from the piston plate 84, the spring 85 returns to its original position, and the piston plate 84 moves upward, drawing in the emulsifier or water through the input pipe 86, thus achieving metered addition.

[0031] like Figure 3 As shown, the bottom of the fixing block 74 is fixedly connected to the top of the stirring shaft 4, and the outer periphery of the stirring shaft 4 is slidably connected to the inside of the transmission cylinder 73.

[0032] It should be noted that the bottom of the fixing block 74 is fixedly connected to the top of the stirring shaft 4, so that the lifting ring 78 can pull the stirring shaft 4 up and down through the fixing block 74. The outer periphery of the stirring shaft 4 is slidably connected to the inside of the transmission cylinder 73, so that the stirring shaft 4 can move up and down.

[0033] like Figure 4 As shown, the first gear 72 and the second gear 75 mesh with each other, and the bottom of the reciprocating screw 76 is rotatably connected to the inside of the cover plate 3.

[0034] It should be noted that the first gear 72 meshes with the second gear 75, enabling the first gear 72 to drive the second gear 75 to rotate. The bottom of the reciprocating screw 76 is rotatably connected inside the cover plate 3, allowing the reciprocating screw 76 to rotate stably.

[0035] like Figure 4As shown, the lifting ring 78 is internally slidably connected to the outer periphery of the transmission cylinder 73, and the threaded block 77 is internally slidably connected to the outer periphery of the guide rod 79.

[0036] It should be noted that the sliding connection between the lifting ring 78 and the transmission cylinder 73 ensures that the transmission cylinder 73 can move up and down while rotating, and the guiding action of the guide rod 79 on the threaded block 77 ensures the stability of the up and down movement.

[0037] like Figure 2 As shown, the bottom of the guide rod 79 is fixedly connected to the top of the cover plate 3.

[0038] It should be noted that the bottom of the guide rod 79 is fixedly connected to the top of the cover plate 3, so that the guide rod 79 is installed stably.

[0039] like Figure 5 As shown, the cam 83 and the piston plate 84 abut against each other, and both the input pipe 86 and the output pipe 87 are equipped with one-way valves.

[0040] It should be noted that the cam 83 and the piston plate 84 abut against each other, so that the cam 83 can push the piston plate 84 to move. The one-way valves of the input pipe 86 and the output pipe 87 prevent liquid backflow and ensure the metering accuracy.

[0041] like Figure 5 As shown, one end of the spring 85 is fixedly connected to the top of the piston plate 84, and the other end of the spring 85 is fixedly connected to the inside of the mounting housing 80.

[0042] It should be noted that the connection method of spring 85 allows spring 85 to be stretched by piston plate 84 to generate elastic force, which assists piston plate 84 in resetting.

[0043] The working principle of this utility model is as follows: High-viscosity asphalt is poured into the mixing tank 1, and a certain amount of emulsifier and water are drawn in through the input pipe 86 of the metering mechanism 8 to prepare for emulsification. The first motor 71 and the second motor 81 are started. The first motor 71 causes the stirring rod 5 to stir up and down, and the second motor 81 controls the metering mechanism 8 to output the emulsifier and water in a metered manner. The emulsifier and water are fully mixed with the high-viscosity asphalt in the mixing tank 1 to form emulsified asphalt. After emulsification is completed, the emulsified asphalt is discharged through the discharge pipe 6 for subsequent asphalt concrete production.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
