Extinguish fire source, it is ensured that explosion and subsequent explosion accident do not occur for deduster, guarantee deduster safe operation, and it is hidden thoroughly to eliminate safety
Suffer from.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the dust pelletizing system with safety interaction function of the utility model.
In figure, 1. dedusters, 2.PLC controller, 3. temperature detection sensors, 4. water spray heads, 5. water pipes, 6. acousto-optic reports
Warning lamp, 7. spark detectors, 8. spark blow-outs, 9. inlet tubes, 10. isolating valve,s, 11. display screens.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of dust pelletizing system with safety interaction function of the utility model, structure is as shown in Figure 1, include 1 He of deduster
PLC controller 2, deduster 1 have entrance and air outlet, and 1 inlet of deduster is connected with inlet tube 9, inlet tube 9 be provided with every
Break valve 10, moves closer to 1 entrance of deduster in inlet tube 9 and is disposed with spark detector 7 and spark blow-out 8, separates
Valve 10 is located at spark blow-out 8 close to the side of 1 entrance of deduster, and temperature inspection is provided at the air outlet of deduster 1
Sensor 3 is surveyed, multiple water spray heads 4 are provided in deduster 1, water spray head 4 is respectively connected with water pipe 5, and water pipe 5 stretches out deduster
It is connect outside 1 and with external water source, temperature detection sensor 3, water spray head 4, spark detector 7, spark blow-out 8, partition
Valve 10 is independently connect with PLC controller 2, and PLC controller 2 is connected separately with audible-visual alarm lamp 6, display screen 11, PLC again
The equipment safety control coordinated control system that unmakes is provided in controller 2.
A kind of course of work of the dust pelletizing system with safety interaction function of the utility model is specific as follows:
The safe temperature value for setting the equipment safety control coordinated control system that unmakes in PLC controller 2, opens deduster 1, powder
Dirt enters inlet tube 9, and spark detector 7 detects whether the dust that inlet tube 9 enters has spark, and will test result and be sent to
In PLC controller 2, spark if it exists, then PLC controller 2 controls spark blow-out 8 and works, the blow-out that will test；
If not monitoring spark, spark blow-out 8 does not work.
Temperature detection sensor 8 detects the temperature at 1 air outlet of deduster, and the temperature at 1 air outlet of deduster is passed
