Description
Technical field
The utility model is related to a kind of defeated coal Screening and crushing systems, concretely relate to a kind of defeated screen in station fine crushing
Broken system.
Background technology
As the fuel coal of power plant cycle fluidized-bed combustion boiler, need to handle using two-stage sieving approach, level-one sieves broken system
System is that roller picker adds annular hammer coal breaker, material size≤300mm, discharging-material size≤30mm；Two level Screening and crushing system is high-amplitude vibration
Dynamic sieve plus reversible plate-hammer crusher, material size≤30mm, discharging-material size≤10mm.Two level sieve is broken to carry out in station fine crushing,
Fire coal is transported to by 4 sections of belt conveyors in station fine crushing after the processing of level-one sieving approach.The broken system of defeated coal in station fine crushing
System, including belt conveyer and the broken coal system above belt conveyer, broken coal system include reversible plate-hammer crusher
With the high-amplitude vibrating screen being positioned above, high-amplitude vibrating screen has connected coal breakage bucket, thin component discharge nozzle and the discharging of thick component
Pipe, the thin component discharge nozzle are located at the surface of the belt conveyer, the thick component discharge nozzle and the reversible hammering
The feed inlet of formula crusher is connected, and the discharge port of reversible plate-hammer crusher also is located at the surface of the belt conveyer, by
Air is inevitably driven by the high speed rotary motion of tup in operation come broken material in reversible plate-hammer crusher
Movement, the air of movement can not be confined in casing, carried out mass exchange with the air outside casing, just generated air blast, the blow rate required
Reach certain value with wind speed, air draft will be carried out by coal breakage bucket entrance, and the material being broken provides enough dust,
Cause dust concentration in station fine crushing exceeded, this also results in the waste of coal resource.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of dust concentrations that can effectively reduce in station fine crushing, and
And the defeated coal Screening and crushing system of the coal dust wasting of resources being used in station fine crushing will not be caused.
In order to solve the above technical problems, the utility model is for the defeated coal Screening and crushing system in station fine crushing, including coal conveying belt
Machine and the broken coal system above belt conveyer, broken coal system include reversible plate-hammer crusher and the height that is positioned above
Width vibrating screen, high-amplitude vibrating screen have connected coal breakage bucket, thin component discharge nozzle and thick component discharge nozzle, the thin component discharging
The discharge port of pipe is located at the surface of the belt conveyer, the thick component discharge nozzle and the reversible plate-hammer crusher
Feed inlet be connected, the discharge port of reversible plate-hammer crusher also is located at the surface of the belt conveyer, further include have it is broken
Dust-extraction unit, the crushing dust collection device include being arranged in broken coal system side and removing above the belt conveyer
There is net wind discharge pipe, the dust return duct being connected with the coal breakage bucket and outlet to be located at belt conveyer for dirt device, deduster
The ash-unloading tube of surface.
The defeated coal Screening and crushing system being used in station fine crushing using the above structure is big when what is generated in reversible plate-hammer crusher
When measuring dust along the progress air draft of coal breakage bucket entrance, the dust return duct being connected with the coal breakage bucket can be by coal breakage bucket entrance
Dust is drained in the deduster and is dusted processing, and coal dust is unloaded through ash-unloading tube to belt conveyer, the sky after dedusting
Gas is discharged by net wind discharge pipe, has on the one hand recycled the coal dust in dust, significantly reduces the waste of coal resource, in addition also pole
The earth reduces the dust concentration in station fine crushing, is conducive to the health of operator in station fine crushing.
Further include being arranged in the reversible plate-hammer crusher discharge port side and being located at as the improvement of the utility model
Micro-power dust remover right over belt conveyer.After above-mentioned technical characteristic, can further it reduce in station fine crushing
Dust concentration, reduce coal resource waste.
