Wherein, described wellhole 1, slush pump 2, slag stock pump 4, slurry adjustment tank 3, cyclone 5 and vibratory sieve etc. are prior art, and figure does not show its detailed construction; The hydrocyclone 5 that cyclone 5 should adopt Malaysian Linatex (anti-nanotesla) company to produce, this cyclone 5 are provided with " fish tail " device made from natural rubber, and this fish tail device is as the outlet of this cyclone 5; After processing through slurry adjustment tank 3, the basicly stable water coal of concentration enters this cyclone 5, after processing through elastomeric " fish tail ", can make the concentration of hydraulic mixture after dehydration constant in 60～70%.
Briefly introduce the course of work of the present utility model:
1. the water coal in wellhole 1 enters slurry adjustment tank 3 by slush pump 2.
2. after the water coal mixes in slurry adjustment tank 3, precipitates, concentration is tending towards evenly, stablizes.The uniform and stable water coal of concentration enters cyclone 5 by slag stock pump 4.
3. the water coal is at the interior rotating separation of cyclone 5, and the water of separating is back to wellhole 1 by cyclone clear water output 5B, and the constant concentration of separating flows on vibratory sieve angled back panel 6 by cyclone mud outlet 5A at 60～70% mud.
4. the vibration of the mud on angled back panel 6 is glided and flow to end sieve plate 7, forms the approximately mud of 100 millimeters of thick layer on end sieve plate 7.The present inventor is called " filter bed " with this layer mud, this filter bed is unprecedented, has the ability that captures very small particle (200 orders are even less), and this ability of filter bed not those skilled in the art recognize that yet, is found first by the present inventor.
" filter bed " vibrates reach on the end of negative angle sieve plate 7, successively." filter bed " inner most moisture are shaken and are flowed in the slurry adjustment tank 3 of vibratory sieve below, and superfine coal dust is taken away by filter bed.Finally, the water content of " filter bed " is no more than 10% and top gradely entrucked and carried away by rubber conveyer 8 as sieve, and the solid particle of (anticipating and namely not caught by filter bed) from vibratory sieve bottom " runing away " and coal dust (this part solid particle and coal dust only account for the seldom part of solid particle and coal dust total amount) enter slurry adjustment tank 3 again, repeat to enter above-mentioned steps 2..Move in circles like this, until the most of solid particle in sump 1 and very fine coal and moisture from, make the water in wellhole 1 become clear.
The above-mentioned course of work is reliable and stable, avoided the problem of job insecurity (separation of water coal is thorough or the blocked situation of separator occurs), inefficiency in the past, reduce the concentration of water coal in sump 1, improved sump 1 utilization ratio, extended digging the cycle clearly of sump 1, improved the ability that mine is resisted water disaster, simultaneously, improve water coal utilization rate, reduced the labour intensity of Coal Mine Staff, improved working environment at coal mines, good economic and social benefit has been arranged.
The research and development explanation:
The utility model forms the thick mud of one deck in the course of the work on sieve plate at the bottom of vibratory sieve 7.The thickness of this layer mud approximately has 100 millimeters, and this is the distinctive media filtration layer of the utility model, and we are referred to as " filter bed ".The section that examines " filter bed " can find, its bottom is larger solid granulates, and from bottom to top granularity reduces gradually, topmost the micaceous fine powder of one deck, this layer fine powder has glossy gloss, is comprised of imperceptible coal dust mud, is exactly the kerosene that we often say.This just shows, distinctive this thick layer of system " filter bed " can capture very small particle (200 orders are even less).
The inventor finds just that by creative work the filter bed on vibratory sieve has this special filtration/capture ability, has enriched the knowledge hierarchy of the art, and then has opened the technological development direction of utilizing this filter bed.
Can the key of water coal piece-rate system of the present utility model normal operation be form " filter bed " on vibratory sieve, and can the concentration that the key that form " filter bed " is slurry reach 60～70% concentration.
The cyclone of anti-nanotesla the 5 bottoms have unique " fish tail " device, supply with the water coal concentration stabilize of the cyclone of anti-nanotesla the 5, can guarantee to be stabilized in 60～70% by the concentration of hydraulic mixture after the cyclone of anti-nanotesla the 5 " fish tail " device.5 of the cyclones that other producer on the market makes are difficult to make concentration of hydraulic mixture to be stabilized in 60～70%.
In order to make the water coal concentration stabilize of supplying with the cyclone of anti-nanotesla the 5, the inventor has adopted the technological means that first makes the water coal mix, precipitate in slurry adjustment tank 3, so just overcome the water coal concentration extremely unsettled defective after mobile slush pump 2 pumpings out in sump 1 in the past, can guarantee the stable normal operation of cyclone 5, guarantee that the concentration stabilize of cyclone 5 outflow slurries 60～70%, creates conditions for forming filter bed.
The vibratory sieve of dehydration use can not be caught granularity less than the particle of 0.3 millimeter in the past, be because water coal concentration is low, can not form filter bed on compass screen surface, only depending on the sieve seam to filter just needs to reduce sieve seam size, sieve seam size is stopped up afterwards less than 0.3 millimeter and is taken place frequently, and causes the result that loses more than gain.Our system because by uniqueness, by the media filtration layer that coal dust forms, i.e. " filter bed " just can catch granularity effectively less than 0.3 millimeter, even micron-sized fine particle under the prerequisite of avoiding stopping up, the water coal is fully filtered.
In addition, the utility model adopts the dynamic circulation dewatering type, is not primary dewatering but the iterative cycles dehydration finally makes water coal in sump 1 " become clear ".Previous System be primary dewatering just everything is just fine, make the possibility that is captured never again after much not having captive pulverized coal particle to escape, thereby reduced the recovery utilization rate of water coal.The dynamic circulation dehydration seems that efficient is low, but it is a dynamic process, as long as still have coal dust in sump 1, system just can work always, and pulverized coal particle just can be quit work immediately by thorough the removing, and therefore, the utility model whole efficiency is still very high.
Test is used
The tiltedly exploitation of bowing is adopted in Zheng's coal group company colliery of accomplishing, and dense from the water coal that working face is discharged, in the past, this mine standage even will dig clearly once sometimes every two or three months in one month, have a strong impact on Safety of Coal Mine Production.Now, accomplished the ore deposit before the water coal enters wellhole, built the preposition sump of the special water coal separation of 200 meters long, new type water coal piece-rate system of the present utility model has been installed on this preposition sump, enter wellhole through system's treated water, on sieve, device is sent by rubber conveyer again.Since this system trial run, system works is stable, and the wellhole cycle of digging clearly extends (not needing half a year at least to dig clearly) greatly, has not only saved a large amount of manpower and materials, has also improved raw coal output, has improved mine water resistant calamity risk ability.
