Foamed asphalt integrated foaming beam for foamed asphalt cold-recycling plant mixing equipment

Abstract

The invention discloses a foamed asphalt integrated foaming beam for foamed asphalt cold-recycling plant mixing equipment. The beam comprises a foamed asphalt spraying beam connected with an asphalt conveying pipeline, and a plurality of asphalt foaming devices are equidistantly and uniformly distributed on the foamed asphalt spraying beam; an inlet end of a matrix hot asphalt nozzle is connectedwith the foamed asphalt spraying beam, and an outlet end of the matrix hot asphalt nozzle is connected with a top end of the asphalt foaming cavity; a gas nozzle and a water nozzle are arranged on a group of opposite side surfaces of the asphalt foaming cavity; a foamed asphalt nozzle is arranged at a bottom end of the asphalt foaming cavity; an air cylinder is arranged on the asphalt foaming device; the output end of the air cylinder is contacted with the matrix hot asphalt nozzle; and the air cylinder, the air nozzle and the water nozzle are connected with an electromagnetic valve. The air cylinder timely switches on and switches off asphalt, and the foaming cavity with a high-pressure air and high-pressure water opposite blowing function effectively forms foamed asphalt. And the asphaltfoaming device continuously sprays foamed asphalt into a stirrer and fully stirs the foamed asphalt with a cold-wet premixed mixture to form a high-quality cold-mixed foamed asphalt mixture.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a foamed asphalt integrated foam beam for foamed asphalt cold recycling plant mixing equipment. Background technique [0002] The mixing system is the core component of the foamed asphalt cold recycling plant mixing equipment, which undertakes the function of mixing high-quality foamed asphalt cold recycled mixture for asphalt pavement construction. The mixing system includes a motor, a reducer, a stirring pot, a stirring shaft, and foamed asphalt The foamed asphalt integrated foamed beam is the core component of the mixing system of the foamed asphalt cold recycling plant, and the quality of the foamed asphalt it continuously sprays determines the quality of the foamed asphalt cold recycled mixture. Pros and cons. [0003] At present, the cold recycling technology of foamed asphalt is still in its infancy in my country. Domestic enterprises and univer...
