Description

The soil discharging facility that a kind of vacuum pump and spoil disposal tank form

Technical field

The present invention relates to a kind of equipment that mud in the mine down-hole sump is cleared up, specially refer to a kind of vacuum pump that at first adopts the mud in the mine down-hole sump is sucked storage mud tank, then will store up the mud of mud tank and put into the spoil disposal tank, the slurry transportation in the spoil disposal tank be arrived a kind of soil discharging facility of appointed place by strength.

Technical background

At present, in the mining operation because ubiquity underground water, some mine also adopts hydraulic method to carry out filling, for underground water and filling water are discharged the earth's surface, guarantee the normal operation in mine, ore has generally all been set up drainage system in the down-hole, and drainage system comprises sump, water pump and drainage pipe.

Ore produces fine ore at mining process owing to the effect of explosion and collision, filling is carried out in the casting resin of general employing powdery when adopting hydraulic fill, under the effect of underflow or filling current, part fine ore and powdery casting resin flow in the sump with current and form mud, if untimely cleaning, the mud sump that will deposit, destroy the drainage underground system, affect the normal operation in mine, therefore, must be in time removing in the sump.Down-hole mud cleaning mainly contains following method:

1, adopts manpower cleaning mud.Adopt the mine of manpower cleaning mud, its drainage system must have two cover sump, and a cover sump is used for water storage, and another set of sump is used for cleaning mud, by being used alternatingly, guarantees the normal operation of drainage underground system.Its shortcoming is: adopt manpower cleaning mud, labour intensity is large; Because have two cover sump, investment is large.

2, adopt spoil disposal tank cleaning mud.Adopt spoil disposal tank cleaning mud, its drainage system generally only has a cover sump, and a plurality of spoil disposal tanks are embedded in the sump bottom, by strength mud are cleaned out sump.Its shortcoming is: adopt a plurality of spoil disposal tanks, investment is large; The spoil disposal tank is embedded in the shaft bottom, is in for a long time in the mud, and equipment easily destroys; The spoil disposal tank can not be discharged the earth's surface with mud, and the mud that part is discharged can enter sump by circular flow.

3, adopt water pump cleaning mud.Some mine mud amount is less, does not consider to build sludge drainage system, directly by drainage system slurry transportation is gone out the earth's surface.Its shortcoming is: water pump is often carried and is contained high silt water, and water pump easily destroys.

Summary of the invention

For the mud in the efficient fast cleaning shaft sump, the invention provides a kind of vacuum pump that adopts the mud in the sump is sucked storage mud tank, then will store up the mud of mud tank and put into the spoil disposal tank, the slurry transportation in the spoil disposal tank be arrived a kind of soil discharging facility of appointed place by strength.

The technical solution adopted for the present invention to solve the technical problems is: storage mud tank is cylindrical pressure vessel, place spoil disposal tank top, above its left end, be provided with admission pipe and vacuum pump joins, content gauge is installed in the top within it, above its right-hand member, be provided with dredging tube and go deep in the sump mud, below its right-hand member, be provided with mud pipe and mud valve is installed.After mud valve was in closed condition, startup vacuum pump, storage mud tank produced negative pressure under the effect of vacuum pump; After negative pressure reached certain value, the mud in the sump flowed into storage mud tank under the effect of negative pressure; After mud reached the content gauge setting height in flowing into storage mud tank, the autoshutdown vacuum pump was opened mud valve, will store up mud injection clock valve hopper in the mud tank, flowed in the spoil disposal tank.

The clock valve is installed on the spoil disposal tank by flange, be used for control mud and flow into the spoil disposal tank, the operating principle of clock valve is: when rack-mount cylinder piston rod and bell piston under the high pressure gas effect move downward, the clock valve is opened, and the mud in the storage mud tank can flow into the spoil disposal tank; When cylinder piston rod and bell piston under the high pressure gas effect moved up to the sealing ring position, the clock valve cut out, and stoped mud to flow into the spoil disposal tank.

The spoil disposal tank is that a kind of up and down two ends are hemisphere, and the centre is cylindrical pressure vessel, places storage mud tank below, and spoil disposal tank upper end is provided with charging aperture, connects with the clock valve by flange; The spoil disposal tank is equipped with air inlet pipe and admission valve at left upper end, at its upper right side conveyance conduit is installed.When closing admission valve, when opening the clock valve, the mud in the storage mud tank can flow in the spoil disposal tank; Behind the canned full mud of spoil disposal, close the clock valve, open admission valve, mud is transported to the appointed place by carrier pipe in the spoil disposal tank under the effect of high pressure gas.

The present invention is by being in the same place the device combinations such as vacuum pump, storage mud tank and spoil disposal tank, can from sump, extract and be transported to mud out appointed place, have that equipment is simple, Operation and maintenance are convenient, conveying capacity is large, long service life, fed distance are long, the small investment advantage.

Below in conjunction with drawings and Examples patent of invention is further specified.
