Cold plant-mixed regenerated asphalt foaming device

Abstract

The invention discloses a cold plant-mixed regenerated asphalt foaming device, which comprises a foaming container, a water storage tank, an asphalt heating storage tank and two atomizing nozzles. The cold plant-mixed regenerated asphalt foaming device is characterized in that: the two atomizing nozzles are arranged on two sides of the foaming container, and a controller is arranged on one side of the foaming container; the water storage tank is connected with one atomizing nozzle through a water delivery pipe, and a plunger type speed regulating pump, a water flow meter, a water pressure gauge and a water pressure regulating reflux pipe are arranged on the water pressure; and the asphalt heating storage tank is connected with the other atomizing nozzle through an asphalt delivery pipe, and a variable frequency speed regulating pump, an asphalt flow meter, a pressure gauge and an asphalt pressure regulating reflux pipe are arranged on the asphalt delivery pipe. The integrated system device integrates multiple functions of heating the asphalt, pumping asphalt and water, foaming the asphalt, metering the asphalt, metering the water and the like into a whole, can be conveniently installed in a stable soil mixing plant, is easy to debug, has the characteristics of energy conservation, environment friendliness and high foaming efficiency, and can realize accurate metering.

Description

technical field [0001] The invention relates to a recycled asphalt foaming device, in particular to a plant-mixed cold recycled asphalt foaming device. Background technique [0002] With the increase in the service life of roads, a considerable proportion of asphalt pavements in my country have entered the period of large and medium maintenance. Traditional maintenance methods have problems such as unreasonable use of old materials, high consumption of pavement materials and energy, and road maintenance is facing major technical challenges. problem. Foamed asphalt cold recycling technology, as a new regeneration construction method, has obvious technical advantages and huge development potential under the background that my country's asphalt pavement has entered the maintenance period and traditional renovation methods have obvious shortcomings. Contents of the invention [0003] The object of the present invention is to provide an energy-saving and environment-friendly fo...
