AI Technical Summary
In the prior art, during the mixing process of preparing smokeless modified asphalt, the temperature difference between inside and outside the mixing tank is large, resulting in uneven heat exposure of the smokeless modifier and local overheating is prone to occur. The high viscosity of the asphalt hinders its uniform mixing with the smokeless modifier, affecting product quality and production efficiency.
An efficient mixing device is designed to optimize the mixing process of smokeless modifier and asphalt through layered stacking and preliminary mixing. The equipment uses a heater and a heating box to initially heat the bitumen to reduce the viscosity, and stir the material at different heights through a stirring rod and a mixing tank. The smokeless modifier is crushed with a transmission and an extrusion roller to increase its contact area with the bitumen.
Through layered stacking and preliminary mixing, a more complete interaction between smokeless modifier and asphalt is achieved, forming more stable and better performance modified asphalt products, avoiding uneven thermal damage of smokeless modifiers, reducing energy consumption and equipment losses, and improving production efficiency.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mixing, and more specifically, to a high-efficiency mixing device for preparing smokeless modified asphalt. Background Art
[0002] The preparation of smokeless modified asphalt mixing equipment plays an important role. In terms of raw material processing and mixing, it can accurately mix the base asphalt, modifiers, additives, etc. in proportion, and disperse the modifier into tiny particles through high-speed shearing to merge with the asphalt. The heating system ensures that the material is in a suitable flow state and the temperature is stable, which is conducive to the mixing reaction, promotes the reaction, creates conditions for the chemical reaction of asphalt and modifier, and changes the chemical structure and properties of asphalt. It is also equipped with quality monitoring and control devices to monitor and control temperature, pressure and other parameters in real time to ensure stable product quality. At the same time, degassing treatment is carried out to improve density. In terms of production efficiency and environmental protection and energy saving, continuous production can be achieved. The automated control system improves efficiency, ensures quality, and reduces human influence. It also adopts high-efficiency heating, sealing and exhaust gas treatment technologies to reduce energy consumption and emissions, achieve environmental protection and energy saving, meet large-scale production needs, and ensure efficient and high-quality production of smokeless modified asphalt.
[0003] In the mixing scenario of preparing smokeless modified asphalt in the prior art, the smokeless modifier and asphalt are generally not pre-treated. The smokeless modifier and asphalt are mostly put into different types of mixing tanks for direct stirring and mixing, and the mixing tank is heated by temperature control equipment. However, in the continuous production process, as the temperature difference between the inside and outside of the mixing tank increases, the temperature difference causes the smokeless modifier to be heated unevenly, which is prone to local overheating and thermal stress concentration. Directly adding the smokeless modifier will cause serious damage, destroy its structure and performance, induce adverse reactions, and affect the quality of the final product. At the same time, the high viscosity of the asphalt in the early stage hinders its uniform mixing with the smokeless modifier, which not only makes the product performance unstable, but also increases energy consumption and equipment loss, reduces production efficiency, and thus affects the economy and feasibility of the entire production process, bringing many adverse effects to production.

[0036] In this embodiment, asphalt and smokeless modifier are transported to the inner side of the material pipe 4 and the material box 5. Under the action of pressure, the asphalt passes through the material pipe 4, the inner side of the corrugated pipe 72 and the inner side of the movable pipe 74 in turn into the inner side of the asphalt port 121. When the asphalt flows through the corrugated pipe, the heat transfer oil preliminarily heats the asphalt to improve the fluidity of the asphalt. The asphalt moves to the top of the auxiliary material port 122 under the guidance of the asphalt port 121. The smokeless modifier passes through the material box 5, the straight pipe 73 and the inner side of the movable pipe 75 in turn into the auxiliary material port 121 under the action of pressure. 22. When the smokeless modifier passes through the inner side of the two squeezing rollers 51, the two squeezing rollers 51 crush the large smokeless modifier particles to increase the contact area between the smokeless modifier and the asphalt. Under the staggered design of the asphalt port 121 and the auxiliary material port 122, the asphalt and the smokeless modifier are guided by the reciprocating motion of the asphalt port 121 and the auxiliary material port 122, and are layered and accumulated on the inner side of the mixing tank 11. At the same time, the stirring rod 93 rotates while reciprocating, thereby preliminarily mixing the asphalt and the smokeless modifier.
[0037] Specifically, the movable parts include four limit rods 113, the four limit rods 113 are fixed to the top of the base 2, the top of the four limit rods 113 are fixed with springs 1, the mixing tank 11 is slidably connected to the outside of the four limit rods 113, the bottom of the mixing tank 11 is penetrated with four circular grooves 112, the other ends of the four springs 1 are fixed to the bottom of the top wall of the four circular grooves 112, the bottom of the mixing tank 11 is fixed with a discharge port 111, the inner side of the discharge port 111 is fixed with a solenoid valve 1, and the bottom of the discharge port 111 is fixed with a telescopic tube 13.

[0050] Asphalt and smokeless modifier are layered and deposited on the inner side of the mixing tank 11 under the staggered design of the asphalt port 121 and the auxiliary material port 122, guided by the reciprocating motion of the asphalt port 121 and the auxiliary material port 122. Meanwhile, the stirring rod 93 rotates while reciprocating, thereby preliminarily mixing the asphalt and the smokeless modifier.
[0051] As the mixture of asphalt and smokeless modifier accumulates inside the mixing tank 11, the mixing tank 11 moves toward the side close to the mixing tank 10, changes its position in the mixing tank 11, and preliminarily stirs the mixture of asphalt and smokeless modifier at different heights;
[0052] When the discharge port 111 moves into the inner side of the docking ring 14, the delivery of asphalt and smokeless modifier is stopped, and the solenoid valve 1 is opened. The mixture of asphalt and smokeless modifier that has been preliminarily mixed enters the inner side of the mixing tank 10 and is stirred by the mixing tank 10. As the mixture of asphalt and smokeless modifier enters the mixing tank 10, the mixing tank 11 returns to its original position under the action of the spring 1, and the asphalt and smokeless modifier are delivered again for a second preliminarily mixing.
