Electrostatic grounding electrode one end and deduster body tight joint, other end ground connection, and earth resistance is less than 10 ohm, and the static that aluminium dust produces can import the earth, reduces buildup of static electricity phenomenon.
Flame detection sensor is installed on sack cleaner body interior sidewall, lays respectively on deduster bottom, middle part and top sidewall, for detecting in real time naked light.
Dry-chemical fire extinguishing controller is arranged in the automatic fire extinguisher distribution control box being fixed well; Dry powder storage box and deduster body are fixedly connected.
Dry powder injection electromagnetic valve is set on dry powder transfer pipeline, and dry powder transfer pipeline enters into deduster inside from the middle top board of deduster body, and from top to bottom, dry powder transfer pipeline top, middle part and bottom all arrange powder nozzle.
In the time that static field intensity detecting sensor or flame detection sensor have triggering signal, dry-chemical fire extinguishing controller is that dry powder injection electromagnetic valve sends control signal, dry powder injection electromagnetic valve is opened, dry powder is transported to powder nozzle by dry powder storage box through dry powder transfer pipeline, spray dry chemical powder, play the effect of effective control from the beginning of fire.
Flue collector electric check valve is arranged on the porch of cleaning shaft end, deduster, is fixedly connected with deduster; In the time having flame detection signal, flue collector electric check valve cuts out, and makes flue dust and burning things which may cause a fire disaster isolation in flue collector, avoids flue dust to cause repeatedly detonation.
Bypass smoke discharging pipe and flue collector are fixedly connected, and in the time having flame detection signal, flue collector electric check valve cuts out, bypass smoke discharging pipe motor-driven valve is opened bypass smoke discharging pipe, make the temporary transient safety of flue dust emptying, avoid static pressure in smelting furnace to raise, cause smelting furnace blowing out phenomenon.
In the time having flame detection signal, compressed air electric check valve can cut out under the effect of control signal, avoids producing compressed air combustion-supporting phenomenon.
Audible-visual annunciator is arranged on outside automatic fire extinguisher distribution control box, and in the time having alarm signal, this device sends sound and light alarm signal, can play fire warning function, and tissue is puted out a fire to save life and property in time, avoids security incident and economic loss.
The utility model can meet aluminum alloy smelting furnace dust pelletizing system to be put out automatically from the beginning of fire, avoids security incident, improves the safe operation coefficient of dust pelletizing system.
