Detailed Description
Example 1
As shown in the figure, the dangerous object conveying safety control system comprises a conveying device, an infrared thermometer 4, a current monitor, a DSC system, a human-computer interface, a frequency converter and a fire extinguishing device, wherein the input end of the DSC system is connected with the external thermometer 4 and the current monitor respectively, the output end of the DSC system is connected with the frequency converter, an alarm and the fire extinguishing device respectively, and the DSC system is connected with the human-computer interface.
The conveying device comprises a conveying motor 1, a spiral feeder hopper 3, a spiral feeder 8, a kickoff 5, a fireproof gate 7 and a feeder chute 10; the frequency converter is electrically connected with the conveying motor 1, and the conveying motor 1 is electrically connected with the spiral feeder 8; the spiral feeder hopper 3 is connected with the feeder chute 10 through the spiral feeder 8, the kickoff 5 is arranged in the spiral feeder, and the fireproof gate 7 is arranged at the joint of the spiral feeder 8 and the feeder chute 10.
The fire extinguishing device comprises a steam tank 12, an electromagnetic valve 11, a pipeline 13 and a nozzle 9; the steam tank 12 is connected with the nozzles 9 through the pipelines 13, the number of the nozzles 9 can be multiple, so that the steam tank 12 is connected with the corresponding nozzles 9 through the pipelines 13 respectively, and the electromagnetic valve 11 is arranged on the pipeline 13 between the steam tank 12 and the nozzles 9; the nozzles respectively face the bin body of the spiral feeder 8 and the bin body 10 of the chute of the feeder; the spiral conveying is sealed, the adoption of steam is more suitable for temperature reduction and fire extinguishment, and the heat value of the rotary kiln feeding cannot be greatly reduced.
When dangerous materials enter from the hopper 3 of the spiral feeder, the conveying motor 1 drives the spiral feeder 8 to operate, the dangerous materials are conveyed to the outlet kickoff 5, the kickoff 5 pushes the dangerous materials to the chute 10 of the feeder, the dangerous materials enter the next section of spiral feeder through the chute 10 of the feeder, and finally the dangerous materials enter the rotary kiln; the feeding of the rotary kiln can not be interrupted, so that the adoption of the multi-section spiral feeder can be used as the buffering of the feeding, and the stability of the feeding of the rotary kiln is ensured.
An infrared thermometer is arranged outside the bin body of the spiral feeder 8 and is connected with a DSC system, and the output end of the DSC system is respectively connected with an alarm, an electromagnetic valve 11, a frequency converter and a fireproof gate 7. When 8 storehouse body surface temperature in the spiral feeder of infrared thermometer 4 detection, temperature signal feeds back to the DSC system, when the temperature surpassed the DSC system and set for the threshold value, the DSC system signals for the buzzer siren, extinguishing device's solenoid valve 11, converter and fire prevention gate 7, buzzer sends the chimes of doom, remind 8 storehouse internal temperature in the staff spiral feeder too high, the converter frequency conversion stops the transport gradually, fire prevention gate 7 closes and prevents that the intensity of a fire from stretching, solenoid valve 11 is opened and then steam in the steam drum gets into in the spiral feeder through the pipeline and puts out a fire or cool down, when pressure in whole conveyor surpasses the biggest bearing pressure of explosion-proof diaphragm, the explosion-proof diaphragm breaks the pressure release, whole system's safety is protected.
Current monitor 2 detects the electric current of carrying motor, and current signal feeds back to the DSC system, and when the electric current exceeded the DSC system and sets for the threshold value, the DSC system sent the signal and gives buzzer siren, converter, and buzzer sends the chimes of doom, reminds staff's electric current too big, can cause conveying blade distortion, and then easily cause conflagration or equipment damage with storehouse body friction, and the converter falls the frequency and stops carrying gradually, and field work personnel inspect the motor and the condition of working a telephone switchboard, further takes measures.
