Abstract

The invention discloses an asphalt warm-mixing foaming system which is used for solving the problem of mixing hot asphalt for high class highways. The system mainly consists of a water storing device, a water feed device, an asphalt foaming device and an electric equipment control device, wherein the water storing device is connected with the water feed device which is connected with the asphalt foaming device; the electric equipment control device is connected with the water storing device, the water feed device and the foaming device; an asphalt foaming pipe in the asphalt foaming device is in a two-layer sleeve structure, wherein an outer casing pipe is a heat transfer oil heating casing pipe, and an inner core pipe is a foam asphalt generating core pipe; splitter plates are arranged at an asphalt inlet part, and fixed helical blades which are orthometric are arranged at the inner part of a pipe cavity of the foam asphalt generating core pipe; water spray nozzles for foaming are symmetrically arranged. Through the adoption of the foaming system, the hot asphalt and water are combined to enable the asphalt to generate foams, so that the stickiness of the asphalt is reduced, the temperature and the time for mixing the asphalt with aggregates are reduced and shortened, and the problems of energy dissipation and low construction efficiency are solved; at the same time, the environmental pollution degree and the production cost are reduced, and the construction is facilitated. The system disclosed by the invention has the advantages of simple and practical structure, easy manufacture, simple control, accurate computation, strong compatibility and the like.

Description

technical field [0001] The invention belongs to the technical field of pavement engineering machinery and equipment, and specifically relates to a foam asphalt production system for warm asphalt mixture production under automatic control, which is specially used for instantaneously and uniformly mixing hot asphalt and normal temperature water, so that the asphalt can be converted in a short time For foam bitumen. [0002] technical background [0003] With the deteriorating environment and the depletion of energy sources, energy conservation, emission reduction, and low-carbon environmental protection have become the focus of widespread concern in society. With the increasing development of traffic roads, there is an increasing demand for asphalt pavement. Traditional high-grade highways mostly use hot-mix asphalt mixture, and hot-mix asphalt mixture has high production temperature, serious pollution, high cost and inconvenient construction. Warm mix foam technology effectiv...
