Description
Technical field
The present invention relates to the bulk solid materials rubber conveyers such as power station, harbour, mine to transport technical field, and in particular to
A kind of binary channels dust suppression deflector chute that the fertilizer for bulk transport system separates.
Background technique
Belt conveyor is a kind of common material transfer equipment, it can be widely used in metallurgy, coal, traffic, electricity
The industries such as power, building materials, chemical industry, light industry, grain and machinery are the important transportation equipment for conveying coal in electric power enterprise.Wherein
The effect of deflector chute is that Critical Item does not scatter outward at the material feeding loaded on belt conveyor, and reliably working is belt conveyor
The necessary condition of normal operation, deflector chute proportion in each component of belt conveyor is although small, but role is very
It is important.
For the dedusting of bulk material intermediate transit point, since there are height difference, material dropping process in chute for trans-shipment point
In, potential energy is constantly converted into kinetic energy, constantly increases with speed, in discharging, generate strong induced air, up to 1-15 meters/
Second.Under the positive pressure of induced air, the dust particles for carrying a large amount of suspensions are spread to deflector chute surrounding, and dust passes through guide
Slot tail, the left and right sides are overflowed, and scene is caused a large amount of dust occur.
Induced air moves under the draw of belt with material, and the high-speed motion of belt can be on belt and material
The air of side generates pluck effect, reinforces induced air.Material and distinguished and admirable generation speed difference make in material fine particle from stream
Middle removing is flown upward, and fugitive dust is formed,
Now widely used deflector chute is usually the sectional area for increasing deflector chute, and setting damping check apron carrys out remission induction
The flow velocity of wind, but the scope of activities and fugitive dust point of dust are also increased simultaneously.Also have and cleaner or spray are increased using multiple spot
Device has reduction induced air and dust, all less desirable, the trans-shipment point that special belt speed freight volume is big, drop is high, dust are even more
It is difficult to administer.
Summary of the invention
The object of the present invention is to provide a kind of binary channels dust suppression deflector chutes of fertilizer separation, by the binary channels knot of deflector chute
Induced air at material and discharging point is separated, contacts induced air with material by structure, reduces fugitive dust, while material is transported in high speed
The less air of contact in dynamic, the dust of generation is few, is decayed by the blocking of choke curtain, can effectively inhibit dust recycling and produce
It is raw.
