Abstract
The utility model relates to an underground coal slime water sedimentation device which comprises a sedimentation pool, a bucket type dewatering elevator, a coal slime scraper, a pumping and discharging pump, a coal slime water feeding pipeline, a coal slime pumping and discharging pipeline and an overflowing water pipeline. The underground coal slime water sedimentation device is characterized in that the sedimentation pool is arranged before coal slime water enters an underground water bin and divided into a first sedimentation zone and a second sedimentation zone. One ore more first sedimentation tanks are arranged in the first sedimentation zone, the bucket type dewatering elevator is arranged in the sedimentation tank, and the coal slime scraper is arranged in the second sedimentation zone. A second sedimentation tank is arranged between the first sedimentation zone and the second sedimentation zone, and the pumping and discharging pump is arranged in the second sedimentation tank. The coal slime water firstly enters the first sedimentation zone to perform sedimentation, the sediment of the coal slime water is dewatered through the bucket type dewatering elevator and is output, the rest of the coal slime water enters the second sedimentation zone, the sediment of the coal slime water is conveyed to the second sedimentation tank where the pumping and discharging pump is arranged through the coal slime scraper and is discharged through the pumping and discharging pump, and overflowing water in the first sedimentation zone and the second sedimentation zone is discharged through the overflowing water pipeline. The underground coal slime water sedimentation device solves the problem that the content of solid particles in the coal slime water entering the underground water bin is high, coal slime is sedimented seriously in the water bin, the coal slime clearing device is abraded severely, and the like.
Description
Technical field
The utility model relates to a kind of underground coal muddy water sedimentation device.
Background technology
The water burst of mine each department flowing in the process of central water sump through the tunnel of respectively adopting, dig scene and remote (the upper myriametre that has), has carried a large amount of coal dusts, coal cinder and other impurity.These contamination precipitations that enter sump form sump alluvial mud to the sump bottom.Deposit in the mud of sump; not only occupy the dischargeable capacity of sump but also when siltation volume was excessive, a large amount of mud can enter in the water distribution The Small Well of main drainage system, sludge granules can strengthen the wearing and tearing of main drainage system; even can stop up the water sucking mouth of main drain pump, jeopardize mine drainage safety.Therefore when sump silt deposit amount reaches the design upper limit amount, can badly influence use and the drainage effect of sump, have to be forced to stop using, enable another sump.The sump of stopping using and need dig clearly immediately.If the coal slurry content in the sump is few, main drainage system just can work so, and the desilting frequency will reduce greatly.And at present, the black water that enters sump is not all done sedimentation both at home and abroad to process, therefore, cause the solid content that enters sump huge, sump desilting difficulty is very large, and hand labor intensity is large, and is seriously polluted to subsurface environment.
Summary of the invention
A kind of underground coal muddy water sedimentation device, described a kind of underground coal muddy water sedimentation device comprises that settling tank, bucket type drainage elevator, mud scraper, pump drainage pump, black water come pipe material, coal slime pump drainage pipeline, overflow water pipeline; It is characterized in that, settling tank is arranged on black water and advances before the shaft sump, settling tank is divided into sedimentation one district and sedimentation two districts, in sedimentation one district, one or more subsiders are set, the bucket type drainage elevator is set in the subsider, two districts arrange mud scraper in sedimentation, subsider is set between Liang Qu, the pump drainage pump is set in the subsider, black water is introduced into sedimentation one district sedimentation, and the sedimentation part is dewatered by the bucket type drainage elevator and exported, and remainder enters sedimentation two districts, the sedimentation part is delivered in the subsider at pump drainage pump place by mud scraper, discharged by the pump drainage pump, the overflow water in He Er district, sedimentation one district is discharged by the overflow water pipeline, and the quantity of each decanting zone is one, two or more, swash plate or inclined tube are set in order to improve settling efficiency in the decanting zone, the bottom of decanting zone tilts, flat or arc.
Pre-sedimentation device of the present utility model has formed the daily cleaning to the pre-sedimentation that enters water-house coal mud water, after mine water enters settling tank, flow velocity slows down, the larger sludge granules of wherein carrying is sedimentation in sedimentation one district under action of gravitation, is suspended in the fine particle further sedimentation in sedimentation two districts in the mine water.Therefore greatly reduce the total amount of the solid particle that flows into the shaft sump inner segment, reach the purpose that reduces shaft sump depths silting.Most desilting work can concentrate on the cleaning of settling tank, because settling tank length is much smaller than shaft sump, and settling tank is arranged in the large lane that possesses ventilation condition, good operation conditions, be convenient to realize the quick desilting of mechanization, and substantially clarified through the black water that sedimentation is processed, this part water enters sump, do not affect the normal operation of sump drainage system, and then realize the mobilism of shaft sump periodic cleaning, multi-level desilting pattern.
