Environmental-friendly asphalt mixture stirring device

Abstract

The invention provides an environmental-friendly asphalt mixture stirring device. On the basis of an original asphalt mixture stirring device, aiming at the characteristics of the device, a full set of dust and waste gas recovery and purification device is additionally arranged for pollution leakage points, so that the public hazards of waste gas and dust are eliminated, and the environment protection is improved.

Description

technical field [0001] The invention relates to the field of asphalt mixing, in particular to an environment-friendly asphalt mixing equipment. Background technique [0002] In high-grade highway construction. At present, most of the road construction adopts asphalt concrete pavement, and the demand for asphalt concrete is also increasing. With the improvement of the scale and grade of urban road construction, the operation process and equipment efficiency of asphalt concrete mixing plants provided by existing suppliers are low, and the pollution is serious, which has become the "bottleneck" of asphalt concrete road engineering construction. The mixing station has begun to form a realistic demand. [0003] The original asphalt mixing plant generally adopts an open or closed structure of steel structure. The waste gas generated by dust and asphalt heavy oil in the production site or steel structure room is blown by the wind, which has adverse effects on the body of the staf...

AI Technical Summary

Problems solved by technology

[0004] 1. When the original equipment is washing the mixing tank, the stone and stone dust are directly placed on the loader or the ground, and the dust is large;

[0005] 2. The original equipment adopts the direct discharge method when discharging, and the harmful exhaust gas is blown by the wind, which is harmful to the human body

[0006] 3. The waste powder discharged by the secondary bag filter is directly discharged to the waste powder pool. The powder is small and dry, and it will flutter everywhere when there is wind, affecting the surrounding environment.

[0007] 4. The original loading hopper has no dust collection device and dust cover, so the dust is very large, which affects the environment

[0008] 5. The original asphalt heating storage tank has no flue gas treatment device, and the harmful gas discharged affects the environment
