Connection；Fan is equipped at the top of pedestal, fan is connected by air hose with experiment box；The side wall of air hose is added equipped with coal dust
Mouthful；Fan is sequentially connected in series with fan swicth, power supply.
Further, check (non-return) valve is equipped in above-mentioned air hose.Check (non-return) valve is made of the boss on valve body and air hose inner wall, boss position
In the lower part of valve body, valve body is round iron plate；Valve body edge is articulated and connected with air hose inner wall.The diameter of valve body is less than the interior of air hose
Diameter, more than the internal diameter for being in charge of inner wall boss.
The utility model provides a kind of miniature coal-dust explosion analogue experiment installation, by being equipped in the base with testing box
The fan and air hose of connection, and the side wall of air hose is equipped with coal dust adding mouth, and coal dust can be uniformly dispersed in experiment；Test box
It is interior to be equipped with temperature sensor and pressure sensor, it can understand blast temperature and pressure in experiment box when intuitively showing coal-dust explosion
Power；Check (non-return) valve is designed in air hose, coal dust can enter experiment box, while in coal-dust explosion by the wind that fan is blown out, only
Inverse valve is closed using its own gravity, is prevented the shock wave effect chassis interior of coal-dust explosion, can be improved the more of this experimental provision
Secondary recycling.This experimental provision is simple in structure, easy to operate, is conducive to that student is allowed to understand intuitive observation coal-dust explosion simulation
Experiment and dust explosion hazard, and can be recycled for multiple times.
