Detailed description of the invention
See Fig. 1, eddy current dust-arrest device of the present invention, is arranged on deflector chute, material blanking tube front (be front with belt speed direction, reversing sense is rear); It comprises, and eddy current cavity 2 is welded and fused with material blanking tube 1 and deflector chute 6; Dirt gas sinker 3 is arranged in eddy current cavity 2; Dust diverter 5, micronic dust adsorption separation system 7, tail envelope curtain 8 is all fixed in deflector chute 6.Dust diverter 5 is located in the front end deflector chute of eddy current cavity, arrange that compression forms successively by counterweight rubber plate 51, industrial canvas 52, polyurethane sheet 53, described charge level of meeting is two blocks of abrasion resistant polyurethane plates 53, then being the industrial canvas 52 of a monoblock, is finally one block of counterweight rubber plate 51 that at least 10mm is thick.Be provided with micronic dust adsorption separation system 7 in the front deflector chute of eddy current cavity, comprise seal cover cap 71, micronic dust adsorption bar 72, fixed mount 73, described seal cover cap and deflector chute upper cover are combined as a whole; Described micronic dust adsorption bar is fixed on fixed mount, described micronic dust adsorption bar is cubic strip structure, wherein, two leptoprosopy are " W " shape, all the other two wide is plane, the width of described micronic dust adsorption separation system is a little large than the width in deflector chute, and described micronic dust adsorption bar is no less than four layers, and micronic dust adsorption bar is between layers staggered to be stacked.
In the present embodiment, eddy current cavity 2 is identical with the width of material blanking tube 1, and eddy current cavity 2 is got through with material blanking tube 1 and deflector chute 6 phase-contact surface, and three in one forms a larger airtight cavity.
In addition, eddy current cavity of the present invention is provided with manhole door 4, and described dirt gas sinker 3 totally three groups, is structure as a whole with eddy current cavity, is arranged at equably between manhole door 4 and material blanking tube 1.
The part that material blanking tube 1 contacts with deflector chute 6 forms α angle with horizontal direction, 50 °≤α≤70 °, if material blanking tube 1 is not this structure originally, can carry out necessary transformation as required when implementing this dust suppression engineering.
When making dust diverter 5, micronic dust adsorption separation system 7, tail envelope curtain 8, their width must be made to be a bit larger tham the inner width of deflector chute 6, such energy sealing is tight, ensure the filter effect of dirt gas, when dust diverter 5, micronic dust adsorption separation system 7, tail envelope curtain 8 are installed, this three bottom and conveyer belt 9 Elastic Contact.
Working process: when belt runs, when material is transported to next belt from a upper belt by material blanking tube, the disorderly air stream that evokes because material falls, makes the material with dust be formed at belt feeder discharging place and flies upward dust in a large number; Belt travels forward and take up induced air in deflector chute, dirt gas in deflector chute along with induced air moves forward, when dirt gas runs into dust separator, dust is separated into two parts, major part dust enters vortex cavity with dirt gas upward movement, the very trickle dust of sub-fraction can pass through dust separator, along with belt induced air continues forward.Material blanking tube place material constantly falls, and air is constantly drained with the whereabouts of material, therefore forms negative pressure and produces suction, enter the dirt gas of vortex cavity under aerodynamic driving, move to material blanking tube direction, in the process, dirt gas will pass through three groups of dirt gas sinkers successively; Under the effect of dirt gas sinker, the kinetic energy of dirt gas is consumed in a large number, and most dust settles down because kinetic energy is not enough to provide it to continue floating aerial power, falls above belt, transports with material; Fraction dust can be less because of its particle, quality is less, remaining aerodynamic force is still enough to make it in atmosphere floating and continues to move to material blanking tube direction, dirt gas that is last and material blanking tube merges together, participate in the motion cycle of next round ... when running into micronic dust adsorption separation system by that fraction fine solid particle of dust separator, will be adsorbed by micronic dust adsorption separation system, separate from air, thus ensure that deflector chute prosopyle end does not have dust loss out.Deflector chute tail end is provided with tail envelope curtain, ensure that deflector chute tail end does not have dust loss out.
After the invention process, solve the problem of belt transportation system transfer point airborne dust well, dust suppression depositing dust, decreases aerial contamination effectively, improves the working environment of post workman.
