Broken arch is in the coal bunker in the working principle and characteristics
Various types of coal bunker, hopper, coal, material stagnation in their positions in vivo blocked, put no, resulting in the production effects of the accident. Broken arch
device is to resolve this situation as a stagnation blocking equipment, installation bunker coal mining enterprises, through the production practice, indeed solve the stagnation
of coal in its warehouse in vivo
Blocking problem, to avoid affecting the production and use of safe and Flexible Roller Conveyor and efficient.
Ground coal mining enterprises, underground, coal washery and others have coal bunker. Due to wet coal bunker, large chunks of coal gangue in the series or for internal
bagging coal within the coal bunker untaken long backlog of stagnation knot together and form can not flow occlusion fault zones, coal bunker under the mouth do not put coal
feeder out of coal, vulgar
Said lag eye. This problem also plagued the production of coal mining enterprises, the traditional processing methods: artificial poke pound, pressure water jetting, explosives,
mechanical vibration. Its effect is poor and unsafe. Broken arch device (also known as air guns and blocking device) is to prevent and eliminate all types of coal bunker coal
bagging, sticky positions
, Blocking eye phenomena such special devices. When using blasting impact energy, no harm, no pollution, reduce labor intensity, to ensure safety in production, is an
economical, ideal security device attempts to prevent the eye.
A broken arch device works
Arch-breaking device is in mine air piping for air as the medium, the use of aerodynamic principles, its internal pressure devices and can realize automatic control of
quick exhaust valve, air pressure can be instantly transformed into air jet power can produce Suddenly a strong airflow Gravity roller conveyor directly into the bulk storage
Coal and other materials occlusion body faulty area, the expansion of such a sudden release of the shock wave, to overcome the static friction of the material, the material
within the container to restore flow again.
Two broken arch Features
Broken arch has a simple structure, easy installation, impact force, easy operation, continuous operation, no damage to the body such positions; jet burst quickly,
effectively destroy bagging, solve the congestion problem, is an ideal device attempts to prevent the eye.
Its use advantages: ① mute action, low noise, no pollution; no leakage design, efficient use of energy; does not compress within the coal bunker; ② minimum maintenance:
simple moving parts, no motor, no bearings, no lubrication; strong jet burst power, effective range
Wai Kwong; ③ spray piston reset immediately after the explosion to block dirty substance inside the silo into the broken arch playing devices; ④ long life, maintenance-free
within a year guns inside.
Of course, for large-scale coal bunker, using a combination of air guns, large force.
