Description
Technical field
The present invention relates to cleaning unit technical field, specifically, be that a kind of technological process is short, integrated level is high, can be continuous
Carry out crushing, classification has the middle coal of discharge refuse function concurrently and selects Novel integrated gasifying device again.
Background technology
Although rich coal resources in China, but coking coal resource is the deficientest, belongs to scarce coal resources.China enters to wash 200,000,000 every year
The coking coal of many tons and rich coal, middle coal productivity averagely more than 30%, greatly Oversized Coking Coal Cleaning Plant wash middle coal ash
Divide relatively low, mostly use as thermal coal, cause the waste of scarce coal resources.The middle coal depth crushing of washing of coking coal selects skill again
Art is proved, and therefrom the coal selected qualified coking coal cleans productivity that dissociates is up to more than 30%, and total clean coal yield can improve
2-6 percentage point, economic benefit is the most notable with social benefit.
But, centering coal carries out direct washing and is difficult to sub-elect qualified cleaned coal again.One of approach solving this problem is logical
Crossing centering coal to carry out depth crushing and select, this degree of depth that can realize coal and spoil is dissociated, follow-up liquid-solid fluid bed to meet
The sorting upper size boundary of separation of coarse slime machine.The disintegrating machine of China's coal separation industry routine mainly includes jaw crusher, hammer
Disintegrating machine, impact breaker, rod-toothed crusher and gyratory crusher etc..Wherein centering coal is broken uses hammer crushing more
Machine and impact breaker, because percussion is easily generated thinner granularity, contribute to dissociating of clean coal and spoil.And hammer into shape
The marker size of formula disintegrating machine is generally 0-10mm, and the marker size of coal impact breaker is 0-15mm, far away can not
Meet the requirement of the sorting upper size boundary of separation of coarse slime 2mm, as only carried out open circuit crushing, then cause follow-up coarse slime to divide
Containing substantial amounts of coarse granule material in the pan feeding of optional equipment (TBS), set owing to this partial material has exceeded separation of coarse slime
Standby effectively sorts upper size boundary, the most often can not get effectively sorting, and directly discharges from underflow, causes serious underflow
Run thick and cleaned coal loss, according to on-the-spot practical experience, if containing substantial amounts of high ash coarse granule material in pan feeding, will be tight
Ghost image rings the bed stability of separation of coarse slime equipment, is unfavorable for obtaining low ash extract coal, causes killing of bed existing time serious
As, affect the properly functioning of separator.In order to avoid the problems referred to above, then the closed circuit crushing process procedure of coal in must increasing,
Installing screening plant after disintegrating machine, the advantage of this closed circuit crushing is to ensure that product granularity meets follow-up separation requirement,
Shortcoming is that equipment is more, and flow process is complicated, and the loading of disintegrating machine increases, occupied ground, and space availability ratio is low, capital construction and
Equipment purchase cost increases, and improves the power consumption of full factory.
Summary of the invention
