Abstract

A foaming device for foamed asphalt comprises a foaming nozzle, a water nozzle, an air nozzle, an asphalt pipe, and an asphalt on-off control mechanism, wherein the water nozzle and the air nozzle are communicated with the foaming nozzle; an asphalt spout communicated with the asphalt pipe is formed on the foaming nozzle; and the asphalt on-off control mechanism is used for controlling whether the asphalt spout is communicated with the foaming nozzle or not. The foaming device is characterized in that two sealed ring-shaped cavities taking the foaming nozzle as a center are formed on the outer wall of the foaming spray nozzle in parallel; a spout communicated with the foaming nozzle cavity of the foaming nozzle is formed on the side wall of each ring-shaped cavity; the sealed ring-shaped cavities are in sealed connection with the water nozzle and the air nozzle respectively, and both arranged below the asphalt spout; and the ring-shaped cavity, which is nearer to the asphalt spout, is connected with the water nozzle. Through the adoption of the foaming device, high-temperature liquid asphalt is in full contact with water and compressed air, so as to improve the quality of the foaming of asphalt, and ensure the efficient foaming of the asphalt; and the problems of scaling and blockage of the asphalt spout are effectively solved.

Description

technical field [0001] The invention belongs to the field of road construction material production equipment, and in particular relates to a foamed asphalt foaming device capable of efficiently foaming and automatically cleaning residual asphalt on asphalt spouts. Background technique [0002] Foamed asphalt technology and pavement material regeneration technology have developed rapidly in recent years, and the foamed asphalt foaming device used to prepare foamed asphalt has also developed accordingly, extending many new structures. [0003] At present, there are two commonly used structures: one is to use a single water nozzle and a single compressed air nozzle arranged in parallel to directly pass into the foaming asphalt foaming cavity. This structure uses point-to-point contact between asphalt, water and compressed air. As a result, a considerable part of asphalt is not in contact with water and air, the foaming effect is not ideal, and the foaming efficiency is not high...
