Background technology
Serious dust pollution can be produced during material transfer, is seriously endangered to safety in production, staff's health care belt.The producer has done the trial of each side in terms for the treatment of flour dust, such as changes cleaner, installs spraying system additional.But by these treating flour dust means, movement system dust concentration is still exceeded, the deflector chute exit dust severe overweight of especially broken machine room transfer station.The visible obvious laying dust in ground after the operation of transfer station belt feeder.
It is as follows that dust pollution produces process:
Material enters at movement system, head cover at the head cover of top belt because material is with belt high-speed motion, and substantial amounts of induced air is brought into internal system at head cover import.At the head funnel of traditional design, material can produce shock with head funnel here, produce substantial amounts of fine dust particles.
Traditional design material blanking tube is straight tube, and is often accompanied by turning, bend design, and material hits, collided each other in these turnings, the place of elbow again, produces substantial amounts of fine dust particles.
This place of discharging point, because material is vertical drop, vertical impact, can produce substantial amounts of fine dusts again herein.
High speed of coming at head cover induced air just carries head funnel, the fine dust particles produced at material blanking tube with the impact of the high speed falling motion of material, toward guide slot space in pour in, and accelerate with material dropping process medium velocity, induced velocity also quickening simultaneously.
This when, substantial amounts of dust and induction air quantity are just filled with guide slot space, induced air carries substantial amounts of dust and gushed out from deflector chute exit, causes serious dust pollution.
