Abstract

The invention discloses a coal washing water separator for separating the moisture of the washed coal in the process of coal washing. The adjusting rod mounted on the end of the top cap of the shell of water separator is adjusted to change the angle alpha. The washed coal is brought into the filter sieve from the feed hopper above the filter sieve and then into the conveyer belt under the discharge end after filtrated. The moisture and the slime drop into the primary and secondary filter screen mounted symmetrically in the shell cavity of the water separator by the electromotor mounted on the wall water separator shell. The silt water mixture after filtrated is connected in the silt water mixture collecting tube at the discharge end of secondary filter screen for region a or b of the water separator shell, flow through the silt water mixture delivery pipe connected therewith into the dewaterer, and then is used as civil fuel mixture after dehydrated. The lower of the shell cavity of the water separator mounts water outlet mounted connected to water-containing trough, where the clean water filtrated in the region c of shell cavity of the water separator through the water outlet recycles utilization. The coal washing water separator can increase coal recovery of 10-15 percent, and has economic benefit, social benefit and generalization value.

Description

Coal-cleaning water distributor

Technical field

The present invention relates to a kind of water knockout drum, relate in particular to a kind of coal-cleaning water distributor that coal cleaning process production is separated moisture in the coal washing that is used for.

Background technology

In coal cleaning process is produced, all contain large quantity of moisture in readymade coal-coal washing through removing stone, horsestone or other foreign material, for with the coal in the coal washing, moisture from, generally all will use sedimentation basin, the water of post precipitation utilizes once more as recirculated water, and sediment is sent into next procedure as readymade coal, as coking process etc., this conventional method or plant area area are big, and initial stage equipment investment costliness is not a kind of desirable method.Remove this, for the water that separates the coal slime in the coal washing or filter in the coal slime has technology or the device that adopts the high frequency sieve, it can play the effect of filtered water, but high frequency riddler skill or device can destroy the grain structure of coal, produce more coal slime, waste greatlyyer, also inconvenience is promoted.

Summary of the invention

The object of the present invention is to provide and a kind ofly can improve the coal-cleaning water distributor that coal yield, the scope of application extensively reach non-environmental-pollution.

For achieving the above object, the technical solution used in the present invention is: the water knockout drum housing of making a cuboid or the square bodily form of metal material (as corrosion resistant plate or common metal sheet material), divide the top cover rear end of water hull body that adjusting rod is installed, sieves that is connected with screen pack of adjustable plate, through hinges the discharge end of sieves is connected the top cover front end of water knockout drum housing, belt conveyor is positioned at the below of sieves discharge end.Above the feed end of sieves hopper is arranged, for coal washing can be gone downstream, between sieves and the water knockout drum housing top cover surface angle α is arranged on sieves, the angular dimension of α can change with the flexible of adjusting rod.On the wall of water knockout drum housing, be equipped with and make water knockout drum housing and the vibrative motor of sieves, be symmetrically installed with N (integer of N=1) group coarse filtration net and thin screen pack on vertical or horizontal both sides of the inner chamber of water knockout drum housing, coarse filtration net, thin screen pack are divided into a district, b district, c district with water knockout drum housing inner chamber, feed opening place at thin screen pack is connected with the mud mixture collecting pipe, mixes the aqueous mixtures collecting pipe and connects the coal washing dewaterer through the mud mixture carrier pipe.Below the water knockout drum housing, have delivery port, water receiving tank is installed, support is housed, use the valve rubber transition between the bottom of support and water knockout drum housing in the bottom of water knockout drum housing near delivery port.The water knockout drum housing bottom becomes the β angle with horizontal plane, the big I at β angle is by the bearing height difference Δ h=h of water knockout drum housing front end or rear end ₁-h ₂Or aspect ratio dh=h ₁/ h ₂Determine desirable Δ h 〉=0 or dh 〉=1.

Adopt a kind of coal-cleaning water distributor that as above technical scheme provides compared with prior art, can obtain following beneficial effect:

1, coal-cleaning water distributor of the present invention to contain the coal amount greater than the coal in 10% the colliery after coal washing can both with coal, moisture from, turn waste into wealth, have great environmental benefit and economic benefit, a coal-cleaning water distributor adds its auxiliary facility, and the coal of recovery is equivalent to a small-size coal mine of producing 100000 tons of coals per year.

2, with regard to equal ature of coal, compare with traditional handicraft, can improve coal yield 10-15%.

3, moisture in the coal slime can be separated, the recyclable recycling of water, the coal slime after anhydrating can be made the admixture of domestic fuel (as honeycomb briquette).

4, be particularly useful for reclaiming coal in the coal tong stone.
