The specific embodiment
From cylinder control cabinet (41) three-phase alternating-current supply being introduced control connects variable-frequency motor (36), infrared temperature-test sensor signal cable to frequency-variable controller, the output of frequency converter three-phase again and is introduced into cylinder control cabinet thermometric control instrument, the plug cable of control head socket (53) is connected to the relevant control logic circuit of cylinder control cabinet (41), has promptly finished the gas circuit of control system, the control connection of circuit after gas source is connected to burning control head gas joint (52);
From pack into the cold bituminous mixture of definite quality of feed hopper (31), connect control cabinet (41) power supply, cylinder enters automatic heated condition, start cylinder (4) slow rotation clockwise, start the heating of combustion gas full premix cambered surface cylindricality infrared combustion machine (19) full power, deflection mechanism (22) deflects to the infrared radiation angle automatically and covers material spacing stopping behind the position at the inclination angle of rollers roll, and simultaneity factor enters the real-time state of a control of heating-up temperature.Rising along with the material heating-up temperature, when temperature reaches first temperature control point of setting, drum rotation speed is accelerated under the adjusting of frequency converter gradually, meanwhile heating power is by the adjusting of control to the combustion gas gas ratio valve, gas quantity is suitably reduced, thereby reduce the burning heating power, cylinder mixing speed and temperature are controlled to be an intelligent fuzzy and regulate model.
Reach the temperature of setting when the bituminous mixture temperature after, as the need discharging, after manually booting the discharging order, fast rotational that cylinder is counterclockwise deflection mechanism simultaneously makes the full premix cambered surface of combustion gas cylindricality infrared combustion machine turn to the discharging direction automatically, makes infrared emanation synchronous with the material rotating direction all the time.When reaching the compound design temperature, in the time of wouldn't needing discharging, the full premix cambered surface of combustion gas cylindricality infrared combustion machine stops heating and enters keeping warm mode, and the cylinder utmost point rotates at a slow speed, be lower than under the heating-up temperature in limited time, control enters low-power and intermittently is incubated heated condition and finishes until discharging automatically.
