Description
Technical field
The utility model relates to a kind of tertiary industry product liquid-solid fluid bed separation coarse slime systems, are particularly suitable for coal separation work
The difficult desulfurization and deashing for selecting coarse slime in skill.
Background technique
China is one using coal as the country of main energy sources, and it is most effective that the sorting of coal is that Coal Clean efficiently utilizes
Measure, coal preparation technique and method gradually mature and perfect, form " major diameter heavy medium cyclone sorting+separation of coarse slime+floating
The three-stage prevailing technology of choosing ".And limit for height (being greater than 1mm) under the sorting granularity of major diameter heavy medium cyclone, flotation is suitable
For upper size boundary in 0.25mm or so, this makes the sorting of coarse slime with regard to necessary.In separation of coarse slime equipment, with two products
Using relatively broad, material size bound fineness ratio controls within 4 times liquid-solid fluid bed separation machine, and the difficult choosing of its sorting
When coal, the efficiency of separation is often low, causes to carry the higher middle coal of ash content in cleaned coal secretly, and is mingled with coal in a large amount of in spoil, most
Showing as cleans ash and ash content in refuse eventually can not guarantee simultaneously.Therefore providing a kind of sorting hardly possible selects the technique of coarse slime just to have very much
It is necessary.
Summary of the invention
Technical problem: purpose of the utility model is to solve current coarse slime material size narrow ranges, sort difficult choosing
When coarse slime, cleans ash and the problem that ash content in refuse can not guarantee simultaneously and the efficiency of separation is low provide a kind of three product liquid
Solid fluid bed separation coarse slime system, the sorting process can relax material size range in fine coal, especially suitable for
Difficulty selects the sorting of coarse slime, can guarantee cleans ash and ash content in refuse simultaneously, and has the relatively high rate of recovery.
Technical solution: the tertiary industry product liquid-solid fluid bed separation coarse slime system of the utility model, including desliming screen, dense media
Cyclone, middle coal magnetic separator, cleaned coal magnetic separator, close Jie's bucket, classifying cyclone, the product liquid-solid fluid bed separation of coarse slime machine of tertiary industry and
Coal sieve bend in coarse slime, the heavy medium cyclone are connected with the oversize of desliming screen, and stream device and desliming are applied in the classification
The screenings of sieve is connected, and the product liquid-solid fluid bed separation of coarse slime machine of tertiary industry is connected with classifying cyclone underflow, described
Coal sieve bend is connected with the outlet of the middle coal slime of the product liquid-solid fluid bed separation of coarse slime machine of tertiary industry in coarse slime, coal arc in coarse slime
The on-the-sieve material outlet of shape sieve is connected with Jie's bucket is closed, and conjunction Jie's bucket is connected with heavy medium cyclone by the road, realizes a rotation
Flow the combination of device coarse grain unpressurized feeding and coarse slime pressurized feeding.
The slot size of the desliming screen is adjustable the sorting for 3~0.25mm coarse slime, can be used for -0.5mm
The sorting of coal slime.
The pipeline that conjunction Jie's bucket is connected with heavy medium cyclone is equipped with high-pressure pump.
The utility model has the advantages that stating technical solution due to having used upper, the utility model can relax pan feeding grain in fine coal
Range is spent, two product dense medium cyclones is applicable not only to, is also applied for three-product HM cyclone, select rough coal especially suitable for difficulty
The sorting of mud, and can guarantee cleans ash and ash content in refuse simultaneously, and have the relatively high rate of recovery.By column diameter expand or it is more
Section series connection is formed by multi-product liquid-solid fluid bed separation of coarse slime, solves current coarse slime material size narrow range, sorts
When difficulty selects coarse slime, cleans ash and the problem that ash content in refuse can not guarantee simultaneously and the efficiency of separation is low, with prior art phase
Than the screen slot size for adjusting desliming screen can be passed through, to the adaptable of raw coal coal slurry content variation, due to being three products, middle coal
Mud can mix tail coal mud either cleaned coal mud, the strong flexibility of technique, middle coal slime as the case may be and enter heavy medium cyclone
In sort again, the clean coal recovery that makes improves.
