Detailed description of the invention
See Fig. 1, coal crushes dust-arrest device of the present utility model, is arranged on the deflector chute 11 in material blanking tube front (be front with belt speed direction, reversing sense is rear); Described vortex cavity 4 is between the first material blanking tube 21 and the second material blanking tube 22, on deflector chute, be communicated with material blanking tube, deflector chute and be combined as a whole; Described circulation chamber is arranged on the side of the first material blanking tube 21 near deflector chute front end, be communicated with the first material blanking tube bottom, to be communicated with deflector chute with the first material blanking tube and to be combined as a whole, first material blanking tube top is coal crushes 5, and the top in circulation chamber is connected with coal crushes by circulating pipe, described circulation chamber is separated into main ring stream chamber 8 and inner loop stream chamber 9 by inner division plate 15, and described dirt gas sinker 3 is arranged in vortex cavity 4, main ring stream chamber 8, inner loop stream chamber 9; Described dust diverter 10, micronic dust adsorption separation system 12, tail envelope curtain 1 is all fixed in deflector chute, described micronic dust adsorption separation system 12 is arranged on deflector chute leading portion, described tail envelope curtain 1 is arranged on deflector chute tail end, and described dust diverter 10 is arranged in the deflector chute below the first material blanking tube 21 and circulation chamber.
As Figure 3-Figure 4, described micronic dust adsorption separation system 12 comprises seal cover cap 121, micronic dust adsorption bar 122, fixed mount 123, and 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.
By counterweight rubber plate 101, industrial canvas 102, polyurethane sheet 103, described dust diverter 10 arranges that compression forms successively as shown in Figure 2, meeting charge level is two blocks of abrasion resistant polyurethane plates, then being the industrial canvas of a monoblock, is finally one block of counterweight rubber plate that at least 10mm is thick.
In the present embodiment, vortex cavity 4, main ring stream chamber 8, inner loop stream chamber 9 are all identical with the width of material blanking tube 2, material blanking tube 2 removes with the part steel plate at main ring stream chamber 8 place of combining with vortex cavity 4 place of combining and material blanking tube 2, makes vortex cavity 4, main ring stream chamber 8 and material blanking tube 2 form a large cavity.
In the present embodiment, vortex cavity 4 has three groups of dirt gas sinkers 3, is arranged at equably between material blanking tube 2.
In the present embodiment, main ring stream chamber 8 has three groups of dirt gas sinkers 3, is arranged between dividing plate 15 and material blanking tube 2.
In the present embodiment, described inner loop stream chamber is provided with manhole door 14, has one group of dirt gas sinker, be arranged between dividing plate and manhole door in it.
In addition, circulating pipe 7 described in the utility model is terminated on the non-working surface of coal crushes 5 supplied materials material blanking tube, under be terminated on main ring stream chamber 8 and inner loop stream chamber 9.
When making dust diverter 10, micronic dust adsorption separation system 12, tail envelope curtain 1, their width must be made to be a bit larger tham the inner width of deflector chute 11, such energy sealing is tight, ensure the filter effect of dirt gas, when dust diverter 10, micronic dust adsorption separation system 12, tail envelope curtain 1 are installed, this three bottom and conveyer belt 13 Elastic Contact.
As shown in Figure 5, working process: when coal crushes runs, when material is transported to next belt from coal crushes 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 diverter, dust is separated into two parts; The larger dust of major part particle enters in eddy current cavity with dirt gas upward movement, and the trickle dust of sub-fraction can pass through dust diverter, along with the continuation of belt induced air forward.
Material blanking tube place material constantly falls, and air is constantly drained with the whereabouts of material, and therefore form negative pressure and produce suction, the dirt gas entering vortex cavity, under aerodynamic driving, moves to material blanking tube direction; In the process, under the effect of dirt gas sinker, the kinetic energy of dirt gas is consumed in a large number; According to aerodynamic principle, 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, and quality is less, and remaining aerodynamic force is still enough to make it in atmosphere floating and continues to the motion of material blanking tube direction, and dirt gas that is last and material blanking tube merges together, and participates in the motion cycle of next round
Major and minor circulation cavity is by circulating pipe and material blanking tube UNICOM, separated by dividing plate between major and minor circulation cavity, according to aerodynamic principle, when having material to pass through in coal crushes running, material blanking tube, take away most of air in material blanking tube, circulating pipe and material blanking tube will produce pressure reduction, and the air in circulating pipe will flow to material blanking tube; Under aerodynamic effect, gas in major and minor circulation cavity constantly upwards flows to material blanking tube by circulating pipe, form air-flow winding, therefore after a large amount of dust that coal crushes produces enter within the scope of circulation cavity by material blanking tube, by aerodynamic effect upwards and the shunting action of dust diverter, major part dust enters in main ring stream cavity, fraction dust enters in main ring stream cavity, dust will by dirt gas sinker, under the effect of dirt gas sinker, the kinetic energy of dirt gas is consumed in a large number; According to aerodynamic principle, most of dust settles down because kinetic energy is not enough to provide it to continue floating aerial power, falls above belt, transports with material.
Part dust can be less because of its particle, quality is less, aerodynamic force is still enough to make it in atmosphere floating, and continue through circulating pipe to material blanking tube direction and move, dirt gas that is last and material blanking tube merges together, and participates in the motion cycle of next round ... be arranged on the micronic dust adsorption separation system of deflector chute front end, energy of adsorption is by extremely trickle a small amount of dust of twice dust diverter, it is separated from air, thus ensures that deflector chute prosopyle end does not have dust loss out.Deflector chute tail end is provided with tail envelope room, ensure that deflector chute tail end does not have dust loss out.
After the utility model is implemented, solve the problem of coal crusher house transfer point airborne dust well, dust suppression depositing dust, decreases aerial contamination effectively, improves the working environment of post workman.
