Abstract
The utility model discloses a kind of spark detection devices, it includes cleaning shaft；The front end of cleaning shaft is equipped with spark detection instrument；Spark detection instrument is electrically connected with signal amplifier；Signal amplifier is electrically connected with the controller；Controller is electrically connected with the solenoid valve；The front end of solenoid valve is connected to by water pipe with high-pressure water tank；The end of solenoid valve is connected to the spray head that cleaning shaft rear end is arranged in；The top of cleaning shaft internal diameter is arranged in spray head.The utility model can detect the Mars that can cause dust explosion, spray fan-shaped water mist by spray head and intercept the Mars for extinguishing headend equipment and generating.Reaction time is 0.3s, i.e., it is 0.3s that fire extinguishing position is reached from discovery spark to spray water mist.Since the wind speed in cleaning shaft is mostly 20m/s or more, the spacing of spark detection instrument and spray head, which is at least 8 meters, could intercept Mars and extinguish, and effectively prevent Mars and enter safety accident caused by inside deduster.
Description
Technical field
The utility model belongs to dust explosion protection equipment technical field, and in particular to a kind of spark detection device.
Background technique
In the prior art, with the raising of environmental requirement, many plank factories, feed factory, grain dust processing factory are all set up
Dedusting, dust collection device.
Dust concentration is very high in dust collection device and pipeline, and persistently there is dust cloud for a long time.It is such
Oxygen content in dust cloud is very high, is difficult to put out on Mars under the background of 20m/s wind speed as long as there is Mars to enter dust device,
It is very easy to light dust cloud, and then causes the burning even generation of explosion accident.According to grinding for explosion-proof research institute, Northeastern University
Study carefully data statistics, the dust explosion due to caused by deduster accounts for the 40% of entire accidental explosion accident.
Therefore, how to prevent spark from entering deduster, be the key that in place of reducing explosion accident.
Summary of the invention
The purpose of this utility model is that there are sparks easily to enter the technology that dust device causes safety accident for the solution prior art
Problem provides a kind of spark detection device, with overcome the deficiencies in the prior art.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of spark detection device, it includes cleaning shaft；
The front end of the cleaning shaft is equipped with spark detection instrument；The spark detection instrument passes through conducting wire and signal amplifier electricity
Connection；The signal amplifier is electrically connected with the controller by conducting wire；
The controller is electrically connected to each other by conducting wire and solenoid valve；The front end of the solenoid valve passes through water pipe and high pressure water
Tank is interconnected；The end of the solenoid valve is interconnected with the spray head that cleaning shaft rear end is arranged in；The spray head is set
It sets on the top of cleaning shaft internal diameter.
In order to guarantee interception effect, the spacing of the spark detection instrument and spray head is 8-15 meters.
In order to improve fire-fighting efficiency, 2-4 spray head is uniformly provided at the top of the cleaning shaft internal diameter.
The utility model can detect the Mars that can cause dust explosion, open solenoid valve by controller, pass through spray
It drenches head and sprays fan-shaped water mist and intercept and extinguish the Mars that headend equipment generates.This equipment reaction time is 0.3s, i.e., from discovery spark
Reaching fire extinguishing position to spray water mist is 0.3s.Since the wind speed in cleaning shaft is mostly 20m/s or more, spark detection instrument and spray
The spacing of leaching head, which is at least 8 meters, to intercept extinguishing for Mars, effectively prevent safety caused by Mars enters inside deduster
Accident.The utility model solves prior art spark and easily enters the technical issues of dust device causes safety accident.
Detailed description of the invention

Device 2 is electrically connected；The signal amplifier 2 is electrically connected by conducting wire with controller 3；
The controller 3 is electrically connected to each other by conducting wire with solenoid valve 4；The front end of the solenoid valve 4 passes through water pipe and height
Pressure tank 5 is interconnected；The end of the solenoid valve 4 is interconnected with the spray head 7 that 8 rear end of cleaning shaft is arranged in；It is described
The top of 8 internal diameter of cleaning shaft is arranged in spray head 7.
In order to guarantee interception effect, the spacing of the spark detection instrument 1 and spray head 7 is 8-15 meters.
In order to improve fire-fighting efficiency, 2-4 spray head 7 is uniformly provided at the top of 8 internal diameter of cleaning shaft.
The utility model can detect the Mars that can cause dust explosion, open solenoid valve and water pump by controller,
Fan-shaped water mist, which is sprayed, by spray head intercepts the Mars for extinguishing headend equipment and generating.This equipment reaction time is 0.3s, i.e., from hair
It is 0.3s that existing spark, which reaches fire extinguishing position to spray water mist,.Since the wind speed in cleaning shaft is mostly 20m/s or more, spark detection
The spacing of instrument and spray head, which is at least 8 meters, could intercept Mars and extinguish, and effectively prevent Mars and enter inside deduster to cause
Safety accident.
The utility model according to AQ 4273-2016 " dust explosion risk place dust pelletizing system technical specification of security ",
" dust explosion risk place dust-precipitator is explosion-proof by GB15577-2007 " safety requlation for dust explosion protection ", GB/T17919-2008
Directive/guide " related request research and development a dust explosion protection equipment, be mainly used for sander, polygon saw in plate industry etc. easily produce
