Brief description
Fig. 1 is a kind of structural representation of crawler type fine coal pressure conveyer device provided in an embodiment of the present invention.
In figure：
1st, housing；2nd, belt wheel；3rd, crawler belt；4th, fine coal outlet；5th, caterpillar teeth；6th, fine coal entrance.
Specific embodiment
Below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
As shown in figure 1, a kind of crawler type fine coal pressure conveyer device that the present invention provides, go out including fine coal entrance 6, fine coal
Mouth 4, housing 1, two crawler belts 3 and the belt wheel 2 for supporting crawler belt 3 and driving it to rotate.
Wherein, fine coal entrance 6, fine coal outlet 4 connect and are located at the two ends of housing 1, crawler belt 3 and belt wheel 2 respectively with housing 1
It is arranged in housing 1, two crawler belts 3 are arranged in juxtaposition and parallel in vertical direction, each crawler belt 3 has two belt wheels 2 to support biography
Dynamic, each belt wheel 2 in the same size, crawler belt 3 tightly overlays on belt wheel 2.Two crawler belts 3 engage, and are driven by the rotation of belt wheel 2
Crawler belt 3 rotates and for the powdery solid of such as fine coal to be transported to fine coal outlet 4 from fine coal entrance 6.Fine coal from fine coal entrance 6 falls
Enter between the caterpillar teeth 5 of crawler belt 3, conveyed with crawler belt 3 motion.
Specifically, the environmental pressure of fine coal entrance 6 is atmospheric pressure environment；The environmental pressure of fine coal outlet 4 is hyperbaric environment, pressure
Power scope is 4.3-8.5Mpa；Caterpillar teeth 5 adopted engagement design, and two crawler belts 3 form sealing in engagement place, make caterpillar teeth
5 have more preferable meshing performance and exhaust performance；The disengaged direction of crawler belt 3 engaging tooth points to fine coal entrance 6；Two crawler belts 3 with
Between housing 1, there is gap, this interstice coverage is 0.01-10mm it is preferable that this interstice coverage is 0.1-1mm.Belt wheel 2 is dynamic
Force mechanisms effect is lower to rotate, and drives crawler belt 3 to rotate, because caterpillar teeth 5 engages sealing in engaging piece, from low-pressure end fine coal entrance
6 fine coal cannot pass through from engaging piece, but drops between the caterpillar teeth 5 of crawler belt 3, from the height of high-pressure side fine coal outlet 4
There is minor leakage in engaging piece in body of calming the anger, due to there is multigroup engaging tooth, constitute classification sealing, gases at high pressure are revealed herein
Amount gradually reduces, and finally hardly reveals.From fine coal entrance 6 and fall into fine coal between crawler belt 3 caterpillar teeth 5 with crawler belt 3
Rotational conveyance exports 4 to fine coal, realizes the transport from environment under low pressure to hyperbaric environment.
Wherein, the 4 high-pressure side gases of fine coal outlet simultaneously can be along the gap between crawler belt 3 and housing 1 to fine coal entrance 6 low pressure
End is revealed, and can run into on-way resistance and the local resistance of gap generation during revealing, due to the presence of resistance
The leakage pressure in gap gradually reduces until close by force with normal pressure side pressure, in the process because the reduction gas volume of pressure is held
Continuous increase (gas produces and expands), therefore its actual volume flow persistently increases, and can increase on-way resistance further and local hinders
Power.
But the rotation reason due to crawler belt 3, the direction that the gas of leakage rotates with crawler belt 3, integrally transport to high-pressure side
Dynamic, and reveal to low-pressure end, it is finally reached a relatively steady state, reveal speed and mass motion similar rate. simultaneously
I.e. gas no longer to outward leakage or is slightly revealed.
Specifically, crawler belt 3 adopts flexible material, and the caterpillar teeth 5 of crawler belt 3 has flexibility, using flexible material, makes crawler belt 3
There is more preferable meshing performance, the fine coal being attached to during engagement on crawler belt 3 can be present between caterpillar teeth 5；Have netted in crawler belt 3
Braid is used for strengthening intensity；Caterpillar teeth 5 quantitative range of two described crawler belt 3 engagement places is 5-30 pair, exports 4 with fine coal
High-pressure side setting the increase of pressure and increase caterpillar teeth 5 quantity of engagement place, with ensure be classified sealing sealing property.
With reference to the crawler type fine coal pressure conveyer device in the embodiment of the present invention, describe the conveying of conveying device in detail
Process.
Belt wheel 2 rotates under actuating unit, drives crawler belt 3 to rotate so that right side track 3 (shown in Fig. 1) clockwise rotates,
Left track 3 rotates counterclockwise, and enters from fine coal entrance 6 with the mixture of inert gas from the fine coal at normal pressure end, fine coal falls
Enter between the caterpillar teeth 5 of crawler belt 3, the rotation with crawler belt 3 is transported to the fine coal of high-pressure side between crawler belt 3 and housing 1 and goes out
Mouth 4, completes to convey.Whole process does not need inert gas to participate in conveying, it is to avoid inert gas (greenhouse gases) is drained into air
Environment.
Pass through the gap between crawler belt 3 and housing 1 from the high-pressure side gas of fine coal outlet 4 to reveal upwards, due to along journey
The effect of resistance and local resistance and crawler belt 3 rotate bring with the impact revealing motion in opposite direction, reach one eventually
Relatively steady state, reveals speed and mass motion similar rate, and that is, gas no longer to outward leakage or is slightly revealed.
The above, only certain specific embodiments of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, all
Should be included within the scope of the present invention.Therefore, protection scope of the present invention should be with described scope of the claims
It is defined.
