Embodiment
With reference to specific embodiment, the present invention will be described.
As depicted in figs. 1 and 2, a kind of unpowered dust removal device, including organic frame 1, the upper end of rack 1 be equiped with along
The feeding belt of feed direction movement, the upper end of rack 1 is equiped with along feed direction in the upper end side of feeding belt to be extended
Slide type closing deflector chute 2.
Wherein, the upper surface of slide type closing deflector chute 2 is equiped with coal spout 31 vertically extending upward, coal spout 31
Inside offer up and down completely through and the coal breakage passage 311 that connects of lower ending opening and slide type closing deflector chute 2 inside, coal breakage
Pipe 31 is equiped with coal charge adjuster 312 in the bottom of coal breakage passage 311.
Further, the upper surface of slide type closing deflector chute 2 is equiped with dust cleaning case 32 in the rear end side of coal spout 31, removes
The inside of dirt case 32 offers the dedusting chamber 321 that lower ending opening is connected with 2 inside of slide type closing deflector chute, dedusting chamber
Stress plate 322 is embedded with 321；Circulation pipe 33 is equiped between the upper end of dust cleaning case 32 and the middle part of coal spout 31, is circulated
The inside of pipe 33 offer extend along circulation pipe 33 and completely through circulation canal 331, the one end open of circulation canal 331
Connected with the coal breakage passage 311 of coal spout 31, another end opening of circulation canal 331 connects with the dedusting chamber 321 of dust cleaning case 32
It is logical.
Further, slide type closing deflector chute 2 fills respectively in the rear end side of the front of coal spout 31, dust cleaning case 32
Equipped with dust and gas separation assembly 4.
In addition, the upper surface of slide type closing deflector chute 2 is equiped with least two along sending in the rear end side of dust cleaning case 32
Expect direction arranged for interval and the circulation decompressor 5 connected respectively with 2 inside of slide type closing deflector chute successively, slide type closing
Deflector chute 2 is equiped with dust and gas separation assembly 4 between two adjacent circulation decompressors 5.
It should further be noted that dust and gas separation assembly 4 includes the dust and gas point for being installed in 2 upper surface of slide type closing deflector chute
From case 41, the inside of dust and gas separator box 41 offers the dust and gas split cavity connected with the inside of slide type closing deflector chute 2
411, it can be equiped with relatively up and downly in dust and gas split cavity 411 in being vertically arranged and bottom stretches to slide type closing
Resistance dirt sealing curtain 42 inside deflector chute 2；
The upper end of dust and gas split cavity 411 is equiped with sealing curtain fixed plate 43, positioned at 43 upper end side of sealing curtain fixed plate and is in
The screw 44 being vertically arranged, the bottom of screw 44 are connected with sealing curtain fixed plate 43, the upper end of resistance dirt sealing curtain 42 with it is close
Seal the upper end connection of curtain fixed plate 43；The upper end of dust and gas separator box 41 is rotatably equiped with nut 45, screw 44
Upper end be spirally connected with nut 45, the upper end of nut 45 set card has movable handwheel 46.
In the course of work of the present invention, coal charge is fallen into hypomere belt, due to height by the coal breakage passage 311 of coal spout 31
The reason for poor, a large amount of negative-pressure air-flows produced by coal charge flow velocity, reaction force make dust with air-flow produce " explosion " point raise up, gas
Stream flows through the dedusting chamber 321 of dust cleaning case 32, and since the inner space of dedusting chamber 321 increases, dust pressure is in dedusting chamber
Release, air-flow strike stress plate 322 in 321, and large dust particle is fallen into belt conveyor, Yu Chenyou under effect of impact
It is drawn in the effect of negative pressure via the circulation canal 331 of circulation pipe 33 in the coal breakage passage 311 of coal spout 31, and with coal
Stream flows into slide type closing deflector chute 2 and carries out subsequent cycle.In above process, air-flow for curvilinear motion and plays slow
The effect of pressure, dust precipitate during exercise, fall into feeding belt.It is emphasized that power-free dust-removing technology is broken
Traditional dust-cleaning principle, with aerodynamic principle, using pressure balance and closed loop circulation style, reduces logistics to greatest extent
The pressure of dust air in conduit, is allowed to tend to balance with exterior space pressure.
When dust is moved with slide type closing deflector chute 2, dust can pass sequentially through dust and gas separation assembly 4, dust and gas point
From component 4 dust and gas centrifugation is carried out by hindering dirt sealing curtain 42.For dust and gas separation assembly 4, resistance dirt sealing curtain 42 can
Lift adjustment is carried out according to the actual requirements, and specific lift adjustment process is as follows：Staff's rotation activity handwheel 46, rotates
Movable handwheel 46 drive nut 45 to rotate, the nut 45 of rotation drives screw 44 to move up and down, 44 band of screw moved up and down
Dynamic sealing curtain is fixed and moved up and down, and then realizes 42 lift adjustment of resistance dirt sealing curtain.
Based on the above situation, it may be appreciated that by said structure design, the present invention have novel in structural design, good dedusting effect,
The advantages of effects of energy conservation and environmental protection is good, and the waste of coal charge can be efficiently reduced and increase the utilization rate of coal charge.
Above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention's
Thought, there will be changes, this specification content should not be construed as to the present invention in specific embodiments and applications
Limitation.
