Abstract

The utility model relates to a real-time automatic dredging device for a coal-mine underground water sump, which is characterized in that a set of endless-rope transporting system is arranged in a tunnel from a water retaining wall to a water sump mouth to drag a forklift truck to move; meanwhile, two sludge wells are respectively dug at two ends, and one sewage submersible pump is installed in each well; the forklift truck does a reciprocating movement to push sludge into the two sludge wells, and the sewage submersible pumps are used for discharging sludge in the sludge wells into a rectilinear vibrating screen by pipelines; sewage enters a sewage depositing box and then is pumped into a pressure filter by a slurry pump; and coal slime excess water of which is dehydrated is in a coal cake shape and can be loaded into a mining car to be shipped out. The equipment system changes the traditional dredging process and overcomes the defect existing during regular dredging, and the effective volume of the water sump can be completely utilized. Most importantly of all, under the condition that the underground water sump is not emptied, the equipment system completes overall processes of absorption, pumping, draining, concentration, dehydration and loading for the coal slime of the underground water sump. The clearance problem troubling coal mines for years is solved.

Description

The real-time automatic desilting device of colliery shaft sump

Technical field

The utility model relates to a kind of coal-mine water-house silt displacement device, particularly long-term work under water, can collect the device of mud in the mine sump under the situation of not emptying of sump automatically.

Background technology

The effect of colliery shaft sump is water and precipitation coal slime.Contain the impurity based on coal slime in the mine water, they can precipitate after entering sump, and these sediments need in time to clear up away, otherwise can reduce the dischargeable capacity of sump.And when long-pending silt was too much, foreign material can enter absorbing well, absorption well and be inhaled into water pump, made the flow passage components wearing and tearing aggravation of water pump, shortened the water pump life-span, increased maintenance workload.Therefore, digging sump clearly is to improve one of Mine Drainage System safety and economy important channel.Dig the conventional method of sump termly clearly: artificial desilting method, mechanization desilting method, plunger dredge pump method, vibrosieve desilting method, filter press desilting, artificial desilting method in real time etc., they each have pluses and minuses separately, in above-mentioned several traditional dredging methods, the following problem of ubiquity: 1. the mine desilting is before arriving rainy season or handles when mud piles with in the sump, the sump dischargeable capacity can not all obtain utilizing, and has potential safety hazard when Shuitu goes out when running in the pit mining; 2. clear up when sump piles with mud, to the time requirement height of bringing down stocks, task is heavy again; Labour intensity is big when 3. bringing down stocks, and operating environment is abominable.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of colliery shaft sump real-time automatic desilting device, without the labor cleaning, can clear up the mud in the sump at any time, do not need regularly to concentrate cleaning, alleviate working strength of workers, allow the dischargeable capacity of sump all be utilized all the time.

Solve the technical scheme that the utility model problem is adopted: this device comprises the waterwall that is located at sump inlet the inside, two sewer catch basins, two submersible sewage pumps, two-way forklift, endless rope winch, sewer catch basin is located between waterwall and the sump inlet and enters the mouth near waterwall and sump respectively, a submersible sewage pump respectively is installed in the sewer catch basin, and submersible sewage pump connects linear vibrating screen through blow-off line; Be provided with a back and forth two-way forklift with the endless rope winch traction of operation in the tunnel between two sewer catch basins.When forklift advanced to sewer catch basin top, coal slime fell into well by deadweight, and the submersible sewage pump startup in the well enters the linear vibrating screen that is installed in outside the Hatch Opening with coal slime by blow-off line and handles.

Good effect of the present utility model is: it is strong that (1) handles the mud ability, and can handle mud 5-20t every day; (2) mechanization level height, labor strength is low, the mud of this system is scraped suction, conveying, muddy water classification, the siccative transportation is mechanization, artificial loading, the manually manual labor of go-cart have thoroughly been changed, reduce recruitment, improved work efficiency, all the operation operation only needs 2 people to make an inspection tour, and work efficiency can improve 5-10 doubly; (3) desilting in real time helps mine safety production, native system can be installed in one of them sump and run without interruption continuously, another sump only uses when suddenly a large amount of water bursts appearance and desilting system overhaul only as the safe spare sump, has improved the safety of waterproof; (4) this system adopts Simens PLC control, has realized the black water pump drainage, concentrates, the automation of dehydration, entrucking; (5) this system's all devices is convenient to install, and moves simply, safe and reliable, and maintenance capacity is little.

The real-time desilting system of shaft sump can be realized shaft sump under the situation of not emptying, finishes absorption to down-hole water warehouse coal slurry, pump drainage, concentrates, the overall process of dehydration, entrucking, has eliminated the difficult problem of bringing down stocks that perplexs the colliery for many years.Have small investment, efficient height, the low and reliable characteristics of running cost, have good economic benefit and social benefit, boundless popularization space and application prospect are arranged.

Description of drawings

Accompanying drawing is a user mode schematic diagram of the present utility model.

The specific embodiment

As shown in drawings, arrange a cover endless-rope system at waterwall 1 to the tunnel 6 of sump mouth: endless rope winch 11 forms electrodeless closed loop by the back and forth operation on 6 floors, tunnel of the two-way forklift 5 of wire rope 10 tractions by tail reverse wheel 2.Between waterwall 1 and sump inlet and respectively near waterwall 1 and sump entrance, respectively dig a

sewer catch basin

4,9, a

submersible sewage pump

3,8 respectively is installed in the sewer catch basin 4,9.Waterwall can calculate according to test of sump silt settling and the sedimentation time of solid particle under the gravitational field effect to the distance of sump inlet.

The course of work of the present utility model is: endless rope winch 11 slowly moves by the two-way forklift 5 of wire rope 10 tractions the mud of deposition is pushed in the sewer catch basin 4, after entering linear vibrating screen 12 by submersible sewage pump 3 by blowoff line 7, sewage enters foul water tank 13, pump into filter press 15 with slag stock pump 14 then, slough the coal slime coal-forming pie of excessive moisture, the mine car 16 of can packing into transports.After two-way forklift 5 moves to the well head place of sink hole 4, stop, oppositely slowly move then to another sewer catch basin 9, mud is pushed in the sewer catch basin 9 equally, discharge by the submersible sewage pump in the well 8, two-way like this forklift 5 moves back and forth between two sewer catch basins 4 and 19 under endless rope winch 11 tractions again, incessantly mud is advanced in two

sewer catch basins

4 and 9, finish real-time desilting task.The above bulky grain sediment of particle diameter 2mm is directly sent into mine car 16 from linear vibrating screen 12 and is transported, and it is temporary that remaining muddy water enters foul water tank 13, pumps into filter press 15 by slag stock pump 14, and the coal-forming pie mine car 16 of packing into transports after the dehydration press filtration.The clear water that filter press 15 comes out reenters sump and is discharged by main pump.
