Abstract

The invention provides a foamed asphalt generating spraying device which comprises a heated asphalt spraying cavity and control units, and further comprises a plurality of foaming units and a heating unit, wherein the heated asphalt spraying cavity is strip-shaped; a first interface and a second interface are respectively formed in two end surfaces of the heated asphalt spraying cavity, and communicated with an asphalt conveying system; each foaming unit comprises an asphalt foaming chamber, a heated asphalt spraying control air cylinder, an asphalt nozzle, a foamed asphalt spraying control oil cylinder, a foamed asphalt outlet, a foaming water conveying pipeline and a foaming air conveying pipeline; each heated asphalt spraying control air cylinder comprises an air pressure control cavity, an air cylinder rod and an air cylinder rod casing pipe; each asphalt nozzle is arranged on the lower end surface of the corresponding air cylinder rod casing pipe; each air cylinder rod is used for controlling the open-close of the corresponding asphalt nozzle; each foamed asphalt spraying control oil cylinder comprises an oil pressure control cavity, an oil cylinder rod and an oil cylinder rod casing pipe; the heating unit comprises heat conduction oil coil pipes arranged in the heated asphalt spraying cavity. Through the adoption of the foamed asphalt generating spraying device, the defects of heated asphalt and emulsified asphalt can be effectively overcome.

Description

technical field [0001] The invention belongs to the field of pavement material regeneration, and relates to a foam asphalt generating and spraying device. Background technique [0002] During the asphalt pavement recycling construction process, the asphalt materials added and mixed into the recycled materials are mainly hot asphalt and emulsified asphalt. However, these two kinds of asphalt materials have the following disadvantages in the use process: hot asphalt, because of its small addition amount (3-5%) in recycled materials, the overall addition volume is small and the viscosity is large, and the mixing time is very short, so It is difficult to mix evenly with recycled materials; emulsified asphalt, the emulsifier contained in it will have an adverse effect on the original properties of asphalt, and special emulsified asphalt equipment is required to prepare, and the cost is high. Contents of the invention [0003] The object of the present invention is to provide a...
