Brief description of the drawings
Fig. 1 the utility model it is a kind of for moisture of coal fines from system pipeline structural representation.
Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
As shown in figure 1, the moisture of coal fines from system include one section of enrichment facility 1 and two sections of enrichment facilities 2.
One section of enrichment facility 1 includes one section of thickener 11, sieve bend 12, sculping screen 13, the sedimentation centrifuge being sequentially connected
14th, centrifugate bucket 15.Two sections of enrichment facilities 2 include being sequentially connected two sections of thickeners 21, purification thickener 22, press filtration enter charging basket
23rd, filter press 24, purification water pool 26.
One section of pipeline of thickener 11 connects two sections of thickeners 21.
One section of thickener 11 connects sieve bend 12, the pipeline of sieve bend 12 connection sedimentation centrifuge 14, sedimentation by pump through pipeline
Centrifuge 14 connects centrifugate bucket 15 by pipeline；Centrifugate bucket 15 sets centrifugate pipeline, and centrifugate pipeline connects one section of concentration
Machine feed pipe.
Two sections of pipelines of thickener 21 connect purification water pool 26, and two sections of thickeners 21 connect purification thickener by pump through pipeline
22, purification thickener 22 enters charging basket 23 by pump through pipeline connection press filtration, enters charging basket 23 again by pump equipped with the press filtration after addition medicament
Filter press 24 is connected through pipeline, purification thickener 22 connects purification water pool 26 with the pipeline of filter press 24.
Utility model works process：Black water injects one section of thickener 11 by one section of thickener feed pipe, concentrated
Afterwards, supernatant water velocity is very big, can flow into two sections of thickeners 21 through pipeline, one section of thickener, 11 2 sections of thickeners 21 are
High-efficiency concentrator, one section of underflow of thickener 11 squeeze into sieve bend 12 through pipeline by pump and carry out giving dewater treatment, and oversize is by conveying
Machine is transported to sculping screen 13 and carries out removing medium, because the position of sieve bend 12 is higher than sedimentation centrifuge 14, sieve lower liquid by pipeline from
Sedimentation centrifuge 14 is flowed into, is dehydrated again under the influence of centrifugal force, the position of sedimentation centrifuge 14 is higher than centrifugate bucket 15, centrifugation
Liquid enters centrifugate bucket 15 by pipeline self, and centrifugate bucket 15 sets centrifugate pipeline, then is flowed again through centrifugate pipeline by pump
Enter one section of thickener feed pipe, and obtain middle coal 16；Supernatant from one section of thickener 11 in two sections of thickeners 21 again
Concentration, what the supernatant after concentration can flow automatically, purification water pool 26 will be flowed into by pipeline, it is impossible to which gravity flow is squeezed into by pump through pipeline
Liquid caused by purification thickener 22, purification thickener also flows into purification water pool 26, two sections of thickeners 21 and purification thickener 22
Caused underflow squeezes into press filtration through pipeline by pump and enters charging basket 23, is squeezed into again by pump through pipeline after adding filter aid and flocculant medicament
Filter press 24, liquid caused by filter press 24 enters purification water pool 26 by pipeline, and obtains fine coal slurry 25.It is also provided with entering two
The centrifugate pipeline of section thickener, when content of ashes is relatively low in coal slime, directly can enter two sections of thickeners by pump through pipeline.
So, centrifugate cycling and reutilization, the slime content for entering two sections of concentration basins is reduced, alleviates accumulation and the argillization of concentration basin coal slime
Phenomenon, increase concentration basin can settling area, alleviate the burden of filtering equipment and the consume of filter cloth, reduce poly- third and alkali aluminium
Deng the usage amount of medicament, improve and wash mixed coal yield, product benefit is reached into maximization.
