Asphalt foaming device and method

Abstract

The invention provides an asphalt foaming device and method. The asphalt foaming device comprises a plurality of independent foaming cavities, a high-pressure water conveying pipeline and an asphalt conveying pipeline; the high-pressure water conveying pipeline and the asphalt conveying pipeline are communicated with all the foaming cavities, feeding ports of the high-pressure water conveying pipeline, the asphalt conveying pipeline and all the foaming cavities are sequentially formed and communicated with one another, the portion, between every two adjacent foaming cavities, on the asphalt conveying pipeline is provided with an asphalt valve, and the high-pressure water conveying pipeline is provided with fluid valves for controlling opening and closing of water paths of all the foaming cavities respectively. According to the asphalt foaming device, all the foaming cavities can simultaneously or independently foam, different quantities of foaming cavities can be controlled to foam according to the proportion of asphalt added when an asphalt mixing device is in use, and therefore the asphalt foaming device can be matched with asphalt mixing devices different in yield for use; meanwhile, through the asphalt butterfly valves and electromagnetic flow valves, the flow rate of asphalt and water can be controlled to control the contact area of asphalt foaming, and the foaming amountof asphalt can be adjusted.

Description

technical field [0001] The invention relates to the technical field of asphalt foaming equipment, in particular to asphalt foaming equipment and a foaming method. Background technique [0002] At present, the country has higher and higher requirements on the environmental protection performance of asphalt mixing equipment. Using foamed asphalt for the production of asphalt mixture can reduce the energy consumption of the equipment, effectively reduce the temperature of the baking material, save more energy, and reduce the production of finished products. The blue smoke made of raw materials is more environmentally friendly, and is suitable for fields with higher requirements for energy saving and environmental protection. [0003] In the prior art, the asphalt foaming equipment used in the field of warm mixing equipment generally has only one foaming chamber, or has multiple foaming chambers but each foaming chamber cannot be foamed independently, so it cannot be used accord...

Problems solved by technology

[0003] In the prior art, the asphalt foaming equipment used in the field of warm mixing equipment generally has only one foaming chamber, or has multiple foaming chambers but each foaming chamber cannot be foamed independently, so it cannot be used according to the asphalt mixing equipment. The ratio of asphalt to be added is matched and adjusted, which is not convenient enough to use
