A kind of asphalt mixture production equipment and its manufacturing preparation process

Abstract

The invention discloses an asphalt mixture production equipment and its manufacturing process. The asphalt mixture comprises the following raw materials in parts by weight: base asphalt, rubber powder, styrene copolymer, tackifier, activator, stabilizer, Eucommia gum, Ultraviolet absorber, asphalt modifier; when the asphalt mixture is used in road construction, it can improve the high temperature resistance and aging resistance of the road, increase the elasticity of the road surface, reduce the generation of cracks, and prolong the service life of the road surface; the production of asphalt mixture The equipment cuts the asphalt raw material through several shearing rods, and several stirring rods stir the asphalt raw material, so that the mixing uniformity of the asphalt raw material is high and the shearing effect is good; the sealing of the production equipment of the asphalt mixture is good, and the internal temperature is basically Constant, avoiding the process of affecting asphalt development due to temperature changes; by moving the stirring rod and shearing rod out of the shearing box, it is easy to clean and has a good cleaning effect.

Description

technical field [0001] The invention relates to the field of asphalt mixture production, in particular to a production equipment of asphalt mixture and a manufacturing preparation process thereof. Background technique [0002] With the rapid development of social economy, people's demand for travel quality is constantly upgrading. In the field of road engineering, how to improve the use function of the road surface and how to provide the society with safer, more comfortable and more environmentally friendly road surface functions has become a new era. The new goal pursued by the transportation department of our country, looking at the frontiers of technology at home and abroad, asphalt pavement has become the first choice for realizing a leap in road surface function and quality due to its outstanding advantages such as high anti-skid performance, low noise, suppression of water mist, prevention of water drift, and reduction of glare. One of the best forms of pavement. [0...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a kind of asphalt mixture production equipment and its manufacturing preparation process: (1) by taking matrix asphalt as main raw material, adding rubber powder in matrix asphalt, rubber powder makes The rubber powder is wetted, swells, and the viscosity increases, taking into account the viscosity, toughness, and elasticity of rubber and asphalt. Styrene copolymer can obviously improve the weather resistance and load resistance of asphalt, and the tackifier can increase the viscosity of asphalt. Improve the viscosity of asphalt, add sulfur to asphalt, improve the softening of asphalt, environmental rubber oil further improves the role of rubber powder in asphalt, ultraviolet absorbers can effectively absorb ultraviolet rays, improve the anti-aging performance of asphalt, asphalt modification The agent improves the high-temperature performance of asphalt, reduces the temperature sensitivity, keeps the low-temperature performance unchanged, and significantly increases the viscosity of asphalt at 60°C, which solves the problem that the existing asphalt has low viscosity and is easy to melt under high-temperature performance when it is used for road construction. , the elasticity of the road surface is low, making the road surface prone to cracks, and the service life of the road surface is short; The shear rod makes a circular motion to cut the asphalt raw material, and the first gears at the bottom of the annular plate pass through the meshing gear column, thereby driving the connecting column and the stirring rod on the connecting post to rotate, and the rotating stirring rod stirs the asphalt raw material , which solves the problem that the existing asphalt processing equipment stirs the asphalt raw materials so that the mixing uniformity of the asphalt raw materials is poor and the shearing effect is not good enough; (3) the seal is sealed by the hook on the sealing cover and the buckle on the feeding part The cover is fixed to the shear box, so that the asphalt mixture production equipment has good sealing performance, and the sealing ring at the bottom of the sealing cover further improves the sealing performance of the device, by heating the heating wire in the heating layer, passing through the insulation layer Heat preservation makes the internal temperature of the device basically constant, which solves the problem that the existing asphalt processing equipment is poorly sealed, and the heat inside and outside the equipment is easy to exchange, making the internal temperature of the equipment change greatly, which is easy to affect the process of asphalt development due to temperature changes; (4) By turning the second hand wheel, the second gear is driven to rotate, thereby driving the power box to move upward on the guide column. When the gear column moves out of the shear box, the rotating guide column rotates in the movable groove. When the gear column Being away from the shearing box, the shearing rod and stirring rod can be cleaned, which solves the problem that the stirring device of the existing asphalt processing equipment is fixed inside the equipment and is not easy to clean
