Pitch mixed material warm-mixing and regenerating equipment

Abstract

The invention discloses pitch mixed material warm-mixing and regenerating equipment. The equipment comprises a pitch mixed material plant-mixing primary system, a pitch mixed material plant-mixing regenerating system, an additive processing system and a tail gas processing system, wherein a pitch sprinkling system in the pitch mixed material plant-mixing primary system is a warm-mixing foam pitch sprinkling system which comprises a foamed pitch foaming device, a foamed pitch water metering device, a pitch metering device and a remote control system. The technical problems of cementation, pitch ageing and the like in traditional pitch mixed material thermal regeneration equipment are effectively solved. The heating temperature required for mixing new aggregate materials and regenerated materials is reduced, and convenience is brought for construction; the pollution of regenerated materials to environment is reduced, so that the working efficiency of the equipment is improved. The equipment has the advantages of simple and practical structure, simplicity in operation and control and stability in work. The equipment is suitable for the production of various pitch mixed materials and regenerated materials, and can be joined and matched with pitch stirring equipment and regenerating equipment for use.

Description

technical field [0001] The invention belongs to the application field of asphalt regeneration technology and asphalt foaming technology, and in particular relates to warm mixing regeneration equipment for asphalt mixture. Background technique [0002] With the rapid development of my country's highway construction, the national highway network has basically formed, and my country's highways will enter a period of large-scale maintenance and renovation. Therefore, the development of asphalt mixture recycling technology has received extensive attention. Recycling technology is to use some or all of the old materials according to different old materials and road renovation requirements. By adding certain asphalt or additives, the formation can fully achieve the same quality as the new mixing mixture, avoid repeated investment, and save costs. Due to the high heating temperature of asphalt concrete recycled by traditional asphalt mixture recycling equipment, the asphalt will age...
