As shown in Figure 3, the utility model foam asphalt generators, its described asphalt delivery system, water conveying system and compressed air system realize automatically control by the PLC control system.
The foam theory of the utility model foundation:
The basic process of asphalt foaming is when cold water drips (environment temperature) and hard pitch (140
0More than the C) when contacting, following chain reaction will occur; Heat (energy) exchange occurs in heated bitumen and little water droplet surface, makes water droplet be heated to 100
0C, simultaneously pitch cooling; The heat of pitch transmission has surpassed steam latent heat, causes volume expansion, produces steam.Steam bubble in the expansion chamber is pushed down into the continuous phase of pitch at certain pressure; Have the pitch of a large amount of steam bubbles to spray from nozzle along with melting, compressed steam expands and makes the pitch that slightly cools off form film-form, and relies on the surface tension of film that bubble is wrapped fully; In expansion process, the surface tension opposing steam pressure that asphalt membrane produces is until a kind of equilibrium state, because the low heat conductivity of pitch and water, this balance generally can be kept the time of several seconds; The a large amount of bubbles that produce in the foaming process exist with a kind of metastable form, and fine foam will be vanished gradually.
The utility model flow control plan:
Foamed cell adopts the jet mixing foaming, and gas release is by the decision of pitch pump delivery, and bitumenpump is by the hydraulic pump indirectly control.The hydraulic pressure pump delivery links mutually with the speed of travel.Be associated with the running gear of equipment by the hydraulic motor of asphalt flow meter, bitumenpump, the system that hydraulic pump forms like this.Make the gas release of foamed asphalt can satisfy constantly the specific requirement of constructing.
According to the structure of equipment, in conjunction with the foaming capacity of each foamed cell, press the quantity that the equipment availability width is arranged foamed cell.The foam generating system of equipment is controlled by PLC control system central processing unit.
When the operation width is less than the Breadth Maximum of the renewable operation of equipment in the practical work process, can adjust at random the spray width of foamed asphalt, make it meet on-the-spot various width requirements.
This foam generating system specific works control procedure:
Before construction, as requested flusher 5 and bitumen pipeline are carried out preheating, satisfy job requirement after system can carry out work.According to the actual requirement of construction, foamed system is set: at first the data with operation are input in the PLC control system; Then pass through to adjust asphalt delivery dynamical system 8, water delivery dynamical system 2, the pressure of air-path control system 6 makes it satisfy the pressure requirement of foaming; The PLC control system is by calculating, and relation control asphalt delivery dynamical system 8 in proportion, and water delivery dynamical system 2 guarantees the requirement of gas release.PLC is according to pressure sensor 18, temperature pick up 19 and flow transmitter 20 on the pipeline that is installed in asphalt delivery system, water conveying system and compressed air system, the signal of output is realized in the course of the work engine speed, the speed of travel, the state of the temperature of pitch, flow, pressure and water is controlled, simultaneously again conversely with signal feedback to the PLC control system.Be subjected to the impact of pitch pressure in the bitumen pipeline in the switching of foamed cell medium pitch opening-closing controller 13, control its switching by the size of PLC control system pressing force.Heated bitumen, water and compressed air carry out jet mixing in foaming chamber 16, begin foaming.By the combination control of PLC control system to water lines control valve 4 and pitch opening-closing controller 13, can carry out the operation of different widths of roadway.Can use 10 pairs of pipelines of pipeline washing device to clean if need after the work.In the utility model, in order to improve the application life of foamed cell, can be coated with at the inner surface of described foamed cell the coating of Wear-resistant, high-temperature resistant.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
