The cylinder charging detector is arranged on cylinder charging aperture place, for detection of the interruption situation of cylinder charging;
The multi-sensor information checkout gear, comprise data acquisition card and Industrial Personal Computer (IPC), the data communication device that described temperature-detecting device, motor current detection device, cylinder charging detector are collected is crossed data acquisition card and is delivered in the Industrial Personal Computer (IPC), Industrial Personal Computer (IPC) is transported to burner control by the early warning criterion signal that calculates the hidden danger that will whether occur catching fire, by the automatic control combustion device load of burner control or close burner.
Further, described flue-gas temperature checkout gear comprises temperature pick up and temperature signal regulation circuit, and described temperature pick up is PT200 film platinum resistor or without armoured thermocouple.
Further, described temperature pick up front end is equipped with for the automatic dust removing apparatus of removing in real time dust on the temperature pick up.
Further, described cylinder charging detector comprises contact baffle plate and inlet amount signal of telecommunication scale unit.
Further, described contact baffle plate adopts wear-resistant metal material to make.
The utlity model has following beneficial effect:
The technical program is from the ignition cause of cylinder, when normal production, drum outlet flue-gas temperature and rate of temperature change thereof are higher, because the inner bed of material of cylinder is thicker, can not cause that cylinder catches fire, if only catch fire the early warning criterion take temperature and rate of temperature change as cylinder, then be easy to cause erroneous judgement, the normal production of impact regeneration agitator; Cylinder includes material when less, in the not high situation of flue-gas temperature, can not cause that also cylinder catches fire, and when stopping charging, how long burner need continue heating simultaneously, relies on artificial experience to be difficult to judge.The utility model includes the material situation in conjunction with load, the cylinder of regeneration bitumen material in thermal field distribution, the cylinder in the cylinder, can accurately judge and whether have the hidden danger of catching fire in the cylinder, and in time early warning criterion signal is transported to burner control, by the automatic control combustion device of burner control load or close burner.
