Fig. 2 is a kind of schematic block circuit diagram of fire-proof and explosion-proof deduster of the utility model.
Embodiment
The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings.
As Figure 1-Figure 2, a kind of fire-proof and explosion-proof deduster, including sequentially connected main air duct 7, dust collector box body 8
With wind turbine 6, spark detector 1, electric control system 2, spark blow-out 3 are further included.
The spark detector 1 is arranged at the front end of main air duct 7；It is in the material of inspiration for detecting in main air duct 7
The no quantity containing spark and spark, and the spark quantity detected can be sent to electric control system 2.
Spark blow-out 3 is arranged at 7 middle-end of main air duct, and is located at 1 rear of spark detector；For being sprayed into main air duct
Enter extinguishant.
Electric control system 2 is used for the signal for receiving spark detector 1 and controls spark according to the signal of spark detector 1
Extinguishing means 3 and wind turbine 6 open close.Specifically, the signal output part of spark detector 1 and the signal of electric control system 2 are defeated
Enter end connection, the signal output part of electric control system 2 respectively with the signal input part of spark blow-out 3 and the letter of wind turbine 6
The connection of number input terminal, when electric control system 2 receives the spark signal of the transmission of spark detector 1, controls spark to put out immediately
The device 3 that goes out starts, and controls wind turbine 6 to close at the same time.After spark blow-out 3 starts, extinguishant is sprayed to spark in main air duct 7
（Such as water, dry powder etc.）Spark is put out；Wind turbine 6 closes eliminate what wind turbine sucked spark into dust collector box body 8 immediately
Suction, makes spark rest on main air duct 7 and is extinguished by spark blow-out 3, prevent its enter dust collector box body 8 trigger fire or
Dust explosion.
In some cases, when the spark quantity that spark detector 1 detects has been over the maximum of spark blow-out 3
Extinguishing value（User can set spark quantity to reach K/N seconds for maximum extinguishing value, such as 20/5s）When, although electric-controlled
System 2 processed sends command signal and starts to spark blow-out 3 immediately, and sends command signal fan 6 immediately at the same time and make wind
Machine 6 stops, but because spark quantity exceedes the maximum extinguishing value of spark blow-out 3 so that spark blow-out 3 can not be flutterred completely
Spark-extinguishing, the spark not put out can enter dust collector box body 8 because of the inertia force of wind turbine 6 and trigger fire and dust explosion,
And spark stream caused by dust explosion can also enter the suction area of Workshop Production operation so as to dust suction of igniting with pipeline
The dust subsequent explosion in region, and cause huge casualties and property loss.
In order to which the spark quantity preferably solved in main air duct 7 has exceeded the feelings of the maximum extinguishing value of spark blow-out 3
Condition, it is preferable that a kind of fire-proof and explosion-proof deduster of the utility model further includes main air duct air inlet switch valve 4, the main air duct
Air inlet switch valve 4 is arranged at 7 end of main air duct, the signal output part of electric control system 2 and the letter of main air duct air inlet switch valve 4
The connection of number input terminal.When the spark quantity that spark detector 1 detects has been over the maximum extinguishing value of spark blow-out 3
When, i.e., when the spark quantity that spark detector 1 detects is more than K/N seconds, electric control system 2 controls spark blow-out
3 start, extension set 6 is closed, while electric control system 2 closes main air duct air inlet switch valve 4 immediately, and cut-out main air duct 7, which leads to, to be removed
The passage of dirt device babinet 8, blocks unnecessary spark to enter in dust collector box body 8, so as to prevent from causing the fire behavior of bigger even
Explosion accident.The main air duct air inlet switch valve 4 is slide valve or pneumatic operated valve.This optimal technical scheme provides a kind of main pipeline
When spark exceedes the maximum spraying extinguishing value of spark blow-out 3, remaining on can prevent spark from entering deduster, so as to reach
Avoid triggering the security risk of fire and dust explosion.
Preferably, a kind of fire-proof and explosion-proof deduster of the utility model further includes the air inlet being arranged on dust collector box body 8
Device 5, the signal output part of electric control system 2 are connected with the signal input part of inlet duct 5.When spark detector 1 detects
To spark quantity have been over the maximum extinguishing value of spark blow-out 3 when, closing main air duct air inlet switch valve 4 and wind
While machine 6, electric control system 2, which also controls, opens inlet duct 5, dust collector box body 8 is admitted air into, to alleviate wind turbine 6
Inertia rotate the negative pressure for making to produce in dust collector box body 8, avoid in a short time can not thoroughly wind turbine 6 out of service to except
8 structure of dirt device babinet causes unnecessary damage, for example is flattened by atmospheric pressure.The inlet duct 5 is switch valve, pressure
Door or pneumatic operated valve.
A kind of fire-proof and explosion-proof deduster further includes alarm device（Not shown in figure）, the signal input of the alarm device
End is connected with the signal output part of spark detector.When spark detector is detected in main air duct there are during spark, start immediately
Alarm device sends sound-light alarm, informs in the material of surrounding people's deduster suction and contains spark, causes being vigilant for people, from
And take corresponding safety measure.
A kind of main air duct air inlet switch valve 4 of fire-proof and explosion-proof deduster of the utility model, some other situation is in wind
Machine 6 needs to close main air duct air inlet switch valve 4 after stopping when, it also can control and close the main air duct air inlet switch valve 4.Need exist for
The situation for closing main air duct air inlet switch valve 4 refers to deduster after stopping using, and dust still has generation in dust collector box body
Spontaneous combustion causes the possibility of dust explosion, if cannot isolate air inlet main pipeline with dust collector box body, then once deduster case
Internal dust produces spontaneous combustion and triggers dust explosion, and caused spark air-flow can also enter the suction of Workshop Production operation with pipeline
So as to the dust for suction area of igniting subsequent explosion occurs for dirt region, and causes huge personnel to hinder Workshop Production operating area
Die and property loss.Therefore, main air duct air inlet switch valve 4 can close in this case, block main air duct 7 and lead to deduster
The passage of babinet 8, avoids unsafe accident from occurring.
The fire-proof and explosion-proof deduster of the utility model using when opening sequence be that main air duct air inlet switch valve 4 is than wind turbine 6
First open or the two is opened at the same time, the beneficial effect so set is to make fan of dust remover 6 open in use, will not be because
It is closed for main air duct air inlet switch valve 4, and caused powerful negative pressure after being opened by wind turbine 6, deduster is caused
Unnecessary damage.
Main air duct air inlet switch valve 4 is in open mode, wind when the fire-proof and explosion-proof deduster of the utility model runs well
Related the adsorbed dust object of air-flow caused by machine 6 enters in dust collector box body normal through main pipeline Pneumatic gate valve,
The inlet duct 5 installed in dust collector box body is closed sealing air tight effect to reach deduster at this time.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
Lead to it will be appreciated by the skilled person that can be to the technical solution of the utility model technical scheme is modified or replaced equivalently, without departing from this
The spirit and scope of utility model technical solution.
