Complete equipment for processing regenerative asphalt concrete

Abstract

The invention relates to a complete sets of equipment for processing regenerated asphalt concrete, belonging to the asphalt processing equipment manufacturing technology field. The equipment comprises: a main frame, a movable combustor, an outer cylinder, an inner barrel of belt driven transmission system, a new skeletal material transporting device with a new skeletal material bin, a conveyer pipe with asphalt pump and waste asphalt regenerative agent pump, a waste asphalt mixing and transporting device with a waste asphalt mixture bin, a powder conveying device with a powder material bin, a completed product conveying device with a completed product bin, and a dust recovering and conveying device with second class cloth bag dust cleaner and a first class whirlwind dust cleaner. The invention has advantages of professional designed and compact conformation and can continuously accomplish the procedures of heating new skeletal material, drying, mixing and stirring with waste asphalt mixed material, new asphalt, waste asphalt regenerating agent and powder material and obtaining grade well matching asphalt concrete.

Description

technical field [0001] The invention relates to a complete set of equipment for processing recycled asphalt concrete, which belongs to the technical field of manufacturing asphalt processing equipment. Background technique [0002] Asphalt pavement has been widely used on urban and rural roads, especially high-grade highways, for its excellent performance such as smooth driving, no reflection, low noise, small dust, convenient maintenance, and little impact on traffic. However, with the prolongation of use time, various lesions will occur on the asphalt pavement under various loads, making the asphalt pavement slowly turn brittle, lose elasticity, gradually harden, appear cracks, potholes, until aging, and cracks. [0003] Asphalt pavement material recycling technology, because it can recycle asphalt concrete waste and old materials, solve the environmental pollution problem of asphalt concrete waste and old materials, and save new asphalt mixture resources, so it has good e...

AI Technical Summary

Problems solved by technology

Cold recycling technology cannot be used on high-grade highway pavement because of its poor product quality; hot-in-place recycling equipment and technology are currently imported, not only expensive, but also narrow in scope of application, and the quality of the road surface is not ideal; Type thermal regeneration is prone to secondary pollution, and the old asphalt is easily burnt and aged due to exposure to open flames, and the utilization rate of old materials is low

The above recycling technologies are difficult to meet the requirements of high-grade pavement use
