Description
Technical field
The present invention relates to experiment teaching aid manufacturing technology fields, and in particular to a kind of remote control dust explosion analog demenstration dress
It puts.
Background technology
Dust explosion refers to combustible dust in the range of explosion limit, encounters heat source (open fire or high temperature), and flame moment passes
Entire mixed dust space is sowed at, chemical reaction velocity is exceedingly fast, while discharges a large amount of heat, forms very high temperature and very big
Pressure, the energy of system are converted into the radiation of mechanical energy and light and heat, have very strong destructive power.
Dust explosion is mostly with aluminium powder, zinc powder, aluminium product grounds travel, various plastic powders, organic synthesis drug
The productions such as intermediate, wheat flour, sugar, sawdust, dyestuff, bakelite ash, milk powder, tea-leaf power, tobacco powder, coal dust, plant fiber dirt
Raw production and processing place.
Dust explosion it is very harmful, lesson is also painful.In order to make public awareness to this harm, especially for dust
It is very urgent to popularize dust explosion knowledge for the industries such as larger mechanical processing, timber, coal.And make trainee intuitively
The harm of dust explosion is remembered with deep impressionly, no more than the demonstration that scene carries out dust explosion.
Dust at present explosion experimental facility metal can and small plastic bottle are simply made, this dust explosion experimental provision
Tank body including being equipped with cover at tank mouth, built-in there are one dust container in the tank body, this container is by rubber tube with inflating
Cylinder connection.During experiment, first the candle lighted is put into tank body, then by cover cap on tank body, then by inflator to appearance
The dust inflated in device in ignition container.And there are following defects in an experiment for the dust explosion experimental provision：Use inflator
When inflating, the flare to burn on candle easily extinguishes, and dust could be ignited by generally requiring repeated multiple times operation, and success rate is low；
It is nearer apart from experimental provision when operating personnel are inflated using inflator, there is certain danger；And if event occurs for experimental provision
Barrier needs disassembly analysis to debug, and dust, which is still flown upward, candle is doubtful extinguishes but cannot be guaranteed completely to extinguish or without Mars, still deposit
In the possibility of explosion, the moment threatens the personal safety of operating personnel.
Invention content
At least one of disadvantages described above or Improvement requirement for the prior art, the present invention provides a kind of remote controls
Dust explosion simulation demonstrating apparatus, igniting are not influenced by pump-up device, and success rate is high, are had and are remotely inflated and remote control work(
Can, it is safe, assembling is readily disassembled, conducive to failure is safely and fast discharged, there is good demonstrating effect.
To achieve the above object, one side according to the invention provides a kind of remote control dust explosion simulation and drills
Showing device, including：Firing lock, dust, stab cap, long-range pump-up device, cavity and firing lock described in remote control

Any one in dirt, plant fiber dirt or its mixture.The appearance that the quality of the dust 2 is formed with firing lock 1 and cavity 6
Product ratio should be in the range of the bound of explosion limit, preferably 80g/m3.So set, it is because dust explosion needs have one
Fixed concentration in addition, the selection of above-mentioned material is convenient, is conducive to improve the reliability of dust explosion and the applicability warp of the present invention
Ji property, is conducive to widely promote and apply.
Cavity 6 is made of transparent material；So set, checking the process of the entire explosion of dust 2 convenient for viewing personnel, deepen
Impression.
Firing lock 1 is placed into after first installation is complete on cavity 6 again, successively will pressure spiral shell 1-5, bullet when firing lock 1 is installed
Spring 1-2, firing pin 1-1 are placed on the vertical direction through-hole corresponding position of upper cover 1-4；With a tooling by vertical direction through-hole push away
Dynamic firing pin 1-1 moves to the latched position of firing pin 1-1, at the same time installs electricity and pulls pin 1-3 locking firing pin 1-1, then removes work
Dress.So set, safe, even if firing pin 1-1 is not pulled pin 1-3 lockings by electricity, firing pin 1-1 is popped up under spring 1-2 effects,
Security risk will not occur, assembling can be re-started.The present apparatus is simple and compact for structure, is easily assembled, can after once having demonstrated
Quick assembling rapid-ignition, has the function of repeatedly continuously being demonstrated in the short time, enables analog demenstration object with deep impression.
Reset condition of the present invention after installation is complete first passes through long-range dress of inflating as shown in Figure 1, when needing demonstration and verification
It puts 5 and provides air source to dust 2, dust 2 raises, is covered with the entire space being made of cavity 6 and firing lock 1, is covered in dust 2
While entire space, remotely powered by control device to gunpowder pin removal 1-3, gunpowder pin removal 1-3 is pulled out back, released to hitting
The constraint of needle 1-1, firing pin 1-1 are moved under spring 1-2 thrusts and gravity, and stamp hits stab cap 4 and is under fire, and ignite dust 2.
The state diagram at present invention effect moment is as shown in Figure 2.
Once the present invention breaks down, as shown in Fig. 2, before fixing a breakdown, by long-range pump-up device 5 constantly to by
It blows in the space that cavity 6 and firing lock 1 are formed so that vertical direction of the dust 2 on upper cover 1-4 in the space leads to
The gas vent discharge that notch on hole, horizontal direction through-hole and cavity 6 is formed, then analytical product carries out accident analysis again.
During such troubleshooting, there is no security risks.
As it will be easily appreciated by one skilled in the art that each technical characteristic is as long as they do not conflict with each other in above-described embodiment
It can be combined with each other.The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in this hair
All any modification, equivalent and improvement made within bright spirit and principle etc., should be included in protection scope of the present invention
Within.
