Energy-saving and environment-friendly oil-stone separation device for road old asphalt mixture

Abstract

The invention discloses an energy-saving and environment-friendly oil-stone separation production device for a road old asphalt mixture, which comprises multiple separation tanks and a feeding device, wherein six separation tanks are arranged and are cylindrical; the separation tanks are uniformly distributed along the circumferential direction; a feed hole is formed in the top of each separation tank and comprises a feed pipe and a feed notch; each feed notch is positioned in the bottom position of each feed pipe and is an inclined pipe; the bottom of each feed notch is connected with the top feed hole of the separation tank; a separation pipeline is arranged at the bottom of each separation tank and is obliquely arranged; multiple screening devices are arranged in the separation pipelines; each screening device comprises a square screening box and a filtering net; multi-layer filtering nets are uniformly arranged in the screening boxes; totally five layers of filtering nets are arranged; the bottoms of the six separation pipelines are connected with a storage device; the storage device is of a structure which is wide in top and narrow in bottom, and the section of the storage device is conical; and an exhaust hole is formed in the bottom of the storage device. A six-in-one separation tank structural design is adopted, the separation efficiency is improved, and the oil-stone separation effect is greatly improved.

Description

technical field [0001] The invention relates to an asphalt mixture oil stone separation device, in particular to an energy-saving and environment-friendly old asphalt mixture oil stone separation device. Background technique [0002] The recovery and reuse of asphalt mixed old materials produced by asphalt pavement maintenance meets the requirements of the national energy conservation and emission reduction policy and the development of circular economy. The recycled materials can be fully utilized, which reduces the cost of road construction and reduces the exploitation of petroleum, stone and other resources At present, although there are other methods for recycling, they all have shortcomings and limitations, and cannot meet the road use standards of new mixtures. Only a new process method-the separation and regeneration technology of old asphalt mixtures for road use, can make The old asphalt mixed materials can be traced back to the source, restored to the asphalt and s...

Problems solved by technology

[0003] Although the first generation experimental prototype of old asphalt mixture oil stone separation for roads is the first in China, it adopts the independent operation mode of each system of manual control and manual detection to soak, filter, clean, evaporate, separate, and process waste asphalt base materials. A series of operations such as recycling, in this series of processes, have high requirements for the control of parameters such as temperature, solvent dosage, soaking time, etc. Manual operation is not only labor-intensive, but also the control accuracy and efficiency are very low, especially in asphalt mixing. In the stage of oil and stone separation of raw materials, a large amount of energy, raw materials, and labor are wasted in the actual use process, and the effect of treating a large amount of old asphalt materials cannot be achieved, resulting in large solvent consumption, which inhibits the economics of equipment use and market promotion.
