Abstract
The invention relate to a sorting technology of coarse coal slime of a coal plant, in particular to coarse coal slime sorting equipment and a technology of the coarse coal slime sorting equipment. The coarse coal slime sorting equipment is characterized by comprising a TBS coal slime sorting machine which comprises a tank body, a feeding well, a turbulent flow plate, a density sensor, an actuator, a discharging valve and an overflow weir. Therefore, the coarse coal slime sorting equipment and the technology are reasonable in design and easy to achieve.
Description
(1) technical field
The present invention relates to coal preparation plant's coarse slime separating process, particularly a kind of separation of coarse slime equipment and technique thereof.
(2) background technology
Coal is the main energy sources of China, accounts for 70% left and right of primary energy at present in China's energy resource structure, and coal principal status of public economy in China's energy agent structure within the future quite long period can not change.Along with the raising of mining mechanization, automation, in coal in China, the content of coal slime is increasing, and particularly 1-0.25mm grade coarse granule sorting technology becomes the challenge that the coal separation industry is new.
The main feature of coarse granule coal slime shows the aspects such as content is large, washability is poor.Conventional coarse slime separating process comprises the sorting etc. that heavily is situated between of TBS sorting, spiral sorting, coal slime.Wherein spiral separating is only applicable to the sorting of easy coal separation; Coal slime heavily be situated between cost high, production management level is required high.Thereby these two kinds of method for separating application have limitation.TBS separating density wide ranges, cost is low, automaticity is high, in China, obtains applying comparatively widely in recent years.But there is following drawback in current TBS sorting process:
1) sieve bend easily stops up sieve aperture, then causes centrifuge pan feeding concentration low, causes that centrifuge metals run out.
2) sieve bend can't effectively remove the high ash content fine grained coal slime in TBS overflow cleaned coal, and the thick cleaned coal of TBS has been caused to pollution, causes cleans ash high, does not reach customer requirements.
3) TBS is used the thickener overflow water as recirculated water, contains high grey fine grained coal slime in the thickener overflow water, further the TBS cleaned coal has been caused to pollution.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of
technique is simple,it is reasonable in design,
be easy to realizeseparation of coarse slime equipment and technique thereof.
The present invention is achieved through the following technical solutions:
A kind of separation of coarse slime equipment is characterized in that: comprise the TBS coal slurry separator, the TBS coal slurry separator comprises that cell body, pan feeding well, turbulence plate, density sensor, actuator, blow-off valve, downflow weir form.
The coarse slime separating process of described separation of coarse slime equipment is characterized in that: comprise the following steps:
A) will be selected in coal slime and clear water feeds TBS coal slurry separator (A) and carries out sorting.
B) mine tailing after TBS coal slurry separator (A) sorting enters the tail coal system, and the TBS overflow flows automatically to further sorting of frequency conversion fine grained separator (B).
C) clear water lays along frequency conversion fine grained separator (B) length direction
3road, spray along the contrary coal stream of frequency conversion fine grained separator (B) same full width orientation for every one, constantly overturn in coal seam, high grey thin mud sees through screen cloth and enters backwater, backwater flows automatically to coal slime thickener (D), and frequency conversion fine grained separator (B) oversize enters coal slime centrifuge (C).
D) obtain cleaned coal after coal slime centrifuge (C) dehydration, centrifugate flows automatically to coal slime thickener (D).
E) after coal slime thickener (D) is concentrated, underflow removes press filteration system, and overflow enters circulating water pool (E).
F) the interior recirculated water of circulating water pool (E) enters circulation and goes to recycle, and redundance enters clear water reserviors (F) by overflow, and supplementary clear water also adds clear water reserviors (F).
G) clear water is delivered to TBS coal slurry separator (A) and frequency conversion fine grained separator (B) by the special-purpose clarified water pump of TBS (G).
The equipment that described coarse slime separating process is used, it is characterized in that: described clarified water pump G adopts adjustable frequency motor, configure control valve, electromagnetic flowmeter and Pressure gauge on the delivery side of pump pipeline, guarantee the flow of clear water and the requirement that pressure meets TBS coal slurry separator A.
The invention has the beneficial effects as follows: utilize frequency conversion fine grained separator to combine with clear water, the thin mud of the high ash of TBS overflow is removed, solved because the thin mud of high ash pollutes and causes the problem that cleans ash is high the TBS cleaned coal, thereby improved the head coal product quality.Compare with traditional handicraft, substantially do not change factory building and arrange, increase the special-purpose clarified water pump of TBS; There is the advantages such as technique is simple, clean coal recovery is high, energy-saving and cost-reducing.
