Embodiment Construction
[0043] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:
[0044] like figure 1 As shown, a foamed asphalt production device includes: hot asphalt tank, water (or foaming agent) tank, air compressor (or compressed air storage tank), hot asphalt feeding device, water (or foaming agent) feeding device Feeding device, air feeding device, foamed bitumen generator and PLC control system; the hot bitumen feeding device feeds hot bitumen from the hot bitumen tank 1 to the foamed bitumen generator 15, and the water (or blowing agent) feeds into the foamed bitumen generator 15. The water (or blowing agent) is fed into the foamed asphalt generator 15 from the water tank (or the blowing agent tank) 3 by the feeding device, and the air is fed from the air compressor or the compressed air storage tank 4 by the air feeding device. into the foamed asphalt generator 15, the hot asphalt, water and air are sprayed and atomized in t...

The invention discloses an automatic production method of a foamed asphalt production device. The device comprises: a hot asphalt tank, a water tank, an air compressor, a hot asphalt feeding device, a water feeding device, an air feeding device, and a foamed asphalt generating device. device and PLC control system; the foamed asphalt generator is mixed with hot asphalt, water, and air to generate foamed asphalt, and the foamed asphalt is homogenized; the hot asphalt, water, and air feeding devices respectively , water, and air are sent from hot asphalt tanks, water tanks, and air compressors to the foamed asphalt generator through pumps, fans, etc.; the PLC control system will measure (hot asphalt, water, air) temperature, flow, pressure signals, etc. It is sent to the PLC controller for control calculation. According to the foaming requirements of foamed asphalt, the cascade control and adjustment of flow, temperature and pressure of hot asphalt, water and air realizes the automatic production of foamed asphalt.
Description
technical field [0001] The invention belongs to the field of asphalt processing, and in particular relates to a foamed asphalt production device, a method for efficiently foaming hot asphalt and realizing automatic production. Background technique [0002] Foamed asphalt is a kind of asphalt containing a large amount of foam formed by the hot asphalt being foamed by foaming medium such as water, water vapor or foaming agent, and numerous bubbles with different diameters are rapidly generated in the hot asphalt. As the volume increases by 10 to 15 times, the surface free energy of asphalt increases accordingly. When the foamed bitumen is mixed with the mineral material, it spreads quickly and evenly on the surface of the mineral material to form an asphalt film, which makes the combination of the bitumen and the mineral material more compact and stronger. It saves the amount of asphalt and improves the efficiency of mixing and construction. [0003] At present, there are ma...
