Embodiment
Referring to Fig. 1, vortex dust-arrest device of the invention, be arranged on deflector chute, in front of material blanking tube (with belt speed direction
To be preceding, opposite direction is rear)；It includes, and vortex cavity 2 is welded and fused with material blanking tube 1 and deflector chute 6；Dust and gas sinker 3 is set
Put in vortex cavity 2；Dust current divider 5, micronic dust adsorption separation system 7, tail envelope curtain 8 are all fixed in deflector chute 6.Dust point
Stream device 5 is located in the front end deflector chute of vortex cavity, is sequentially arranged by counterweight rubber plate 51, industrial canvas 52, polyurethane sheet 53
Compression forms, and described charge level of meeting is two blocks of abrasion resistant polyurethane plates 53, followed by the industrial canvas 52 of a monoblock, is finally one piece
Counterweight rubber plate 51 thick at least 10mm.It is vortexed in the front deflector chute of cavity and is provided with micronic dust adsorption separation system 7, including sealing
Lid 71, micronic dust adsorption bar 72, fixed mount 73, the closure are combined as a whole with guide groove upper cap；The micronic dust adsorption bar is consolidated
It is scheduled on fixed mount, described micronic dust adsorption bar is cubic strip structure, wherein, two leptoprosopy are " W " shape, and remaining two wide face is flat
Face, the width of described micronic dust adsorption separation system is a little bigger than the width in deflector chute, and described micronic dust adsorption bar is no less than
Four layers, micronic dust adsorption bar between layers is staggeredly stacked.
In the present embodiment, it is identical with the width of material blanking tube 1 to be vortexed cavity 2, vortex cavity 2 and material blanking tube 1 and deflector chute 6
Phase-contact surface is got through, and three in one forms a bigger airtight cavity.
In addition, vortex cavity of the present invention is provided with manhole door 4, totally three groups of the dust and gas sinker 3, with vortex cavity
Body is structure as a whole, and is evenly arranged between manhole door 4 and material blanking tube 1.
Material blanking tube 1 and the part that deflector chute 6 contacts and horizontal direction shape are at an angle, 50 °≤α≤70 °, if material blanking tube 1 is former
Not being this construction, necessary transformation can be carried out as needed when this dust suppression engineering is implemented.
When making dust current divider 5, micronic dust adsorption separation system 7, tail envelope curtain 8, it must be slightly larger than their width and lead
The inner width of hopper 6, it can so seal the filter effect for tightly, ensureing dust and gas, installation dust current divider 5, micronic dust absorption point
During from system 7, tail envelope curtain 8, this three bottom and the Elastic Contact of conveyer belt 9.
The course of work：When belt is run, material from a upper belt next belt is transported to by material blanking tube when, due to thing
The disorderly air stream that material falls and evoked so that the material with dust forms in belt feeder discharge pit and largely flies upward dust；Skin
Band travels forward and induced air is taken up in deflector chute, dust and gas in deflector chute as induced air moves forward, when dust and gas runs into powder
During dirt separator, dust is separated into two parts, and most of dust is moved into vortex cavity upwards with dust and gas, and sub-fraction is very
Trickle dust can be by dust separator, as belt induced air continues forward.Material is constantly fallen at material blanking tube, air with
The whereabouts of material and constantly drain, therefore formed negative pressure and produce suction, into vortex cavity dust and gas in aerodynamic driving
Under, moved to material blanking tube direction, in the process, dust and gas will pass sequentially through three groups of dust and gas sinkers；In the work of dust and gas sinker
Under, the kinetic energy of dust and gas is largely consumed, most dust because kinetic energy be not enough to provide its continue to float it is aerial dynamic
Power and settle down, fall on above belt, transported with material；Fraction dust can be smaller because of its particle, and quality is smaller, remains
Remaining air force is still enough to allow its floating to continue to move to material blanking tube direction in atmosphere, and finally the dust and gas with material blanking tube is converged
It is combined, participating in the motion cycle ... of next round, that fraction fine solid particle runs into micronic dust absorption point by dust separator
During from system, it will be adsorbed by micronic dust adsorption separation system, be separated from air, so as to ensure that deflector chute prosopyle end will not
There is dust loss to come out.Deflector chute tail end is provided with tail envelope curtain, ensure that deflector chute tail end does not have dust loss and come out.
After the present invention is implemented, solves the problems, such as belt transportation system transfer point airborne dust well, effectively dust suppression depositing dust, subtracts
Lack air pollution, improve the working environment of post worker.
