Specific embodiment
Referring to Fig. 1, coal breaker dust-arrest device of the invention is arranged on material blanking tube front (with belt speed direction as preceding, instead
Direction is rear) deflector chute 11 on；The vortex cavity 4 between the first material blanking tube 21 and the second material blanking tube 22, deflector chute it
On, connected with material blanking tube, deflector chute and be combined as a whole；The circulation chamber is positioned close to the first material blanking tube 21 of guide front of the slot
Side, connected with the first material blanking tube bottom, connected with the first material blanking tube and deflector chute and be combined as a whole, the first material blanking tube top
It is coal breaker 5, and the top in circulation chamber is connected by circulating pipe with coal breaker, and the circulation chamber is built dividing plate 15 and is separated into
Main ring stream chamber 8 and inner loop stream chamber 9, the dust and gas sinker 3 is arranged on vortex cavity 4, main ring stream chamber 8, in inner loop stream chamber 9；It is described
Dust current divider 10, micronic dust adsorption separation system 12, tail envelope curtain 1 are all fixed in deflector chute, the micronic dust adsorption separation system
12 are arranged on deflector chute leading portion, and the tail envelope curtain 1 is arranged on deflector chute tail end, and the dust current divider 10 is arranged on the first blanking
In deflector chute below pipe 21 and circulation chamber.
As Figure 3-Figure 4, the micronic dust adsorption separation system 12 includes closure 121, micronic dust adsorption bar 122, fixes
Frame 123, the closure is combined as a whole with guide groove upper cap；The micronic dust adsorption bar is fixed on fixed mount, and described is micro-
Dirt adsorption bar is cubic strip structure, wherein, two leptoprosopy are " W " shape, and remaining two face wide is plane, described micronic dust adsorbing separation
The width of 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 between layers
Adsorption bar interlocks and is stacked.
Dust current divider described in the as shown in Figure 2 dust current divider 10 is by counterweight rubber plate 101, industrial canvas 102, poly-
Urethane plate 103 is sequentially arranged compression and forms, and described charge level of meeting is two blocks of abrasion resistant polyurethane plates, followed by a monoblock industrial sail
Cloth, is finally the thick counterweight rubber plates of one piece of at least 10mm.
In the present embodiment, vortex cavity 4, main ring stream chamber 8,9 width all with material blanking tube 2 of inner loop stream chamber are identical, material blanking tube 2
Remove with the part steel plate at the place of being combined of main ring stream chamber 8 with the place of being combined of vortex cavity 4 and material blanking tube 2, make vortex cavity 4, master
Circulation chamber 8 forms a large cavity with material blanking tube 2.
In the present embodiment, vortex cavity 4 has three groups of dust and gas sinkers 3, is evenly arranged between material blanking tube 2.
In the present embodiment, main ring stream chamber 8 has three groups of dust and 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, and one group of dust and gas sinker is had in it, sets
Between dividing plate and manhole door.
In addition, being terminated on circulating pipe of the present invention 7 on the non-working surface of the supplied materials material blanking tube of coal breaker 5, lower termination
On main ring stream chamber 8 and inner loop stream chamber 9.
When making dust current divider 10, micronic dust adsorption separation system 12, tail envelope curtain 1, must be slightly larger than their width
The inner width of deflector chute 11, can so seal tight, it is ensured that the filter effect of dust and gas, install dust current divider 10, micronic dust and inhale
During attached piece-rate system 12, tail envelope curtain 1, this three bottom and the Elastic Contact of conveyer belt 13.
As shown in figure 5, the course of work：When coal breaker runs, material is transported to next skin from coal breaker by material blanking tube
During band, the disorderly air stream evoked because material falls so that the material with dust is formed largely in belt feeder discharge pit
Fly upward dust.Belt travels forward and induced air is taken up in deflector chute, and dust and gas are in deflector chute as induced air is moved forward.When
When dust and gas run into dust current divider, dust is separated into two parts；The larger dust of most of particle moved upwards with dust and gas into
Enter in vortex cavity body, the trickle dust of sub-fraction can be by dust current divider, as belt induced air continues forward.
Material is constantly fallen at material blanking tube, and air is constantly drained with the whereabouts of material, therefore is formed negative pressure and produced suction
Power, the dust and gas into vortex cavity are moved under aerodynamic driving to material blanking tube direction；In the process, in dust and gas energy dissipating
In the presence of device, the kinetic energy of dust and gas is largely consumed；According to aerodynamic principle, most dust are not enough to carry because of kinetic energy
Aerial power is floated for its continuation and settled down, fallen above belt, transported with material；Fraction dust meeting
Because its particle is smaller, quality is smaller, and remaining air force is still sufficient for its floating and continues to material blanking tube direction in atmosphere
Motion, finally the dust and gas with material blanking tube are merged together, and participate in the motion cycle ... of next round
Major and minor circulation cavity is separated between major and minor circulation cavity by circulating pipe and material blanking tube UNICOM by dividing plate, according to
Aerodynamic principle, when having material to pass through in coal breaker operating, material blanking tube, takes away most of air, circulation in material blanking tube
Pipe will produce pressure difference with material blanking tube, and the air in circulating pipe will flow to material blanking tube；It is major and minor in the presence of air force
Gas in circulation cavity constantly flows upwardly toward material blanking tube by circulating pipe, forms air-flow winding, thus coal breaker produce it is big
After amount dust is entered in the range of circulation cavity by material blanking tube, by upward aerodynamic effect and dust current divider
Shunting action, most of dust enters in main ring stream cavity, and fraction dust enters in main ring stream cavity, and dust will be by dust and gas
Sinker, in the presence of dust and gas sinker, the kinetic energy of dust and gas is largely consumed；According to aerodynamic principle, most of powder
Dirt settles down because kinetic energy is not enough to provide it continues to float aerial power, falls above belt, with material
Transport.
Part dust can be smaller because of its particle, and quality is smaller, and air force is still sufficient for its floating in atmosphere, and continues
Moved to material blanking tube direction by circulating pipe, finally the dust and gas with material blanking tube are merged together, the motion for participating in next round is followed
Ring ... is arranged on the micronic dust adsorption separation system of guide front of the slot, and energy of adsorption is extremely trickle by twice dust current divider
A small amount of dust, it is separated from air, so as to ensure that deflector chute prosopyle end does not have dust loss out.In deflector chute
Tail end is provided with tail envelope room, it is ensured that deflector chute tail end does not have dust loss out.
After the present invention is implemented, coal crusher house transfer station airborne dust is solved the problems, such as well, effectively dust suppression depositing dust, reduces
Air pollution, improves the working environment of post workman.
