Asphalt steam thermal cycle foaming system

Abstract

The invention provides an asphalt steam thermal cycle foaming system. According to the asphalt steam thermal cycle foaming system, stirring rods and a connecting rod are arranged in a stirring box, the stirring rods are arranged on the two sides of the connecting rod respectively to be in symmetrical distribution, the stirring rods and the connecting rod are in meshing transmission through transmission gears and driven gears at the two ends, the first stirring rod is connected with a motor, a gas inlet pipe and an electric hydraulic machine, the second stirring rod is connected with the electric hydraulic machine and the gas inlet pipe, the two sides of the bottom of the stirring box are provided with a material feeding pipe and a material discharge pipe, the top of the stirring box is connected with a water tank, the side face of the bottom of the water tank is provided with a water inlet pipe, the top of the water tank is provided with a gas collecting ball tank, the gas collecting ball tank is provided with a barometer, a gas conveying pipe penetrates through a heating box to be connected with the gas collecting ball tank and the gas inlet pipe, an electronic valve is arranged between the gas collecting ball tank and the heating box, and the gas inlet pipe and the stirring rods are connected through rotating couplers. By means of the asphalt steam thermal cycle foaming system, accurate proportioning of asphalt and water can be realized, water vapor and the asphalt can be stirred more uniformly, the foaming quality of the asphalt is improved, and waste of energy is reduced.

Description

technical field [0001] The invention relates to the field of asphalt production and processing, in particular to an asphalt steam thermal cycle foaming system. Background technique [0002] Foamed asphalt is a new material that adds water droplets to high-temperature asphalt to form steam bubbles, which produces a chain reaction and significantly improves the bonding performance. The viscosity and polymerization of foamed asphalt are stronger than ordinary asphalt, and foamed asphalt can be stored for a long time and can be cold rolled In addition, foamed asphalt has the advantages of energy reduction, green environmental protection, etc., and has attracted extensive attention from the domestic and foreign highway industries. [0003] In the existing asphalt foaming process, the heated asphalt is usually placed in the mixing chamber to mix and foam with air and water droplets. The water outlet of the existing foaming device is usually fixed, and the water droplets are contin...

Problems solved by technology

[0003] In the existing asphalt foaming process, the heated asphalt is usually placed in the mixing chamber to mix and foam with air and water droplets. The water outlet of the existing foaming device is usually fixed, and the water droplets are continuously sprayed through the same part. This process easily leads to uneven asphalt foaming; it is difficult to control the amount of water injected into the asphalt in the form of water droplets during the foaming process, resulting in an imbalance in the ratio of asphalt and water, which affects the quality of asphalt foaming; the process of asphalt mixing also Need to maintain a high temperature (usually 180°C), the heat is usually dissipated naturally in addition to maintaining the temperature of the asphalt, wasting more resources
