Description
Technical field
The utility model belongs to mining equiment technical field, further belongs to mining with stowing equipment technical field, specifically relates to
And a kind of structure is simple, and it is easy to maintenance, using reliable, the vertical sand warehouse bottom infundibular ganglion of sand export abrasion can be effectively reduced
Structure.
Background technique
In mining, the method for mining by the way of filling is more common mining methods.Mining with stowing artificial supporting mining codes owned by France.
In mineral building or nugget, with the propulsion of stope, it is sent into filler to goaf, to carry out underground pressure management, control
Country rock avalanche and surface movement, and back production is carried out in the obturation of formation or under its protection.The advantages of filling method is to adapt to
Property it is strong, ore recovery rate is high, and the rate of dilution is low, and operation is safer, can utilize industrial waste, protect earth's surface etc.；The disadvantage is that technique is multiple
Miscellaneous, at high cost, labor productivity and nugget production capacity are all lower.In the technique filled to goaf, vertical sand warehouse
It is main equipment.Vertical sand warehouse be the 1980s occur a kind of main units for hydraulic filling, usually by
8 ~ 10m of diameter, 18 ~ 20m of height cylinder with and bottom hemisphere or cone with certain cone angle form.Vertical sand warehouse can connect
The mortar (weight concentration 60~70%) for equably releasing higher concentration continuously is convenient for the filling of underground high-concentration ore slurry, sand warehouse
Dischargeable capacity is big, and effective rate of utilization is up to 70~80%.Keep vertical sand warehouse tailing-filled and obtains more and more extensive answer in mine
With.But current vertical sand warehouse has the disadvantage that
1, vertical sand warehouse bottom funnel serious wear.Tailings is sunk by self weight, and gravity haulage passes through sand bar bottom funnel
It is put into the filling system of lower end, the tailings ore pulp at concentrations up to 70% or more has extremely strong abrasive forces, sand bar bottom funnel steel plate
(δ=20mm) passes through use in 3.5 years, is washed abrasion, thickness is less than 10mm.
2, since main sand pipe uses common seamless steel pipe, and main sand pipe upper end and vertical sand warehouse bottom funnel
Feed opening welding, causes main sand pipe serious wear.
3, due to the bell mouth of vertical sand warehouse bottom and main sand pipe serious wear, often there is needle-like injection sand leakage, deposit
In the risk largely leaked.
It is easy to maintenance for this purpose, it is simple to research and develop a kind of structure, using reliable, sand export abrasion can be effectively reduced
Vertical sand warehouse bottom funnel structure is the key that solve the problems, such as this.

The vertical sand warehouse bottom funnel structure of sand mouth abrasion.
The purpose of this utility model is achieved in that including the short tube that shakes out, wear-resisting partition, metal-ceramic composite tube, master
It is sand pipe control valve, main sand pipe, spare cleaning pipe, spare sand pipe control valve, spare sand developing tube, spare sand pipe, vertical
Sand bar bottom funnel, setting is shaked out short tube at the bottom discharge port of the vertical sand warehouse bottom funnel；The short tube that shakes out
Inside be arranged metal-ceramic composite tube；Wear-resisting partition is arranged between short tube and vertical sand warehouse bottom funnel in described shaking out；Institute
Main sand pipe is arranged in the lower section for the short tube that shakes out stated；Main sand pipe control is arranged in described shaking out between short tube and main sand pipe
Valve；Spare sand developing tube and spare sand pipe are not arranged for the end portion of the vertical sand warehouse bottom funnel；It is described spare to put
Spare sand pipe control valve is set on sandpipe；Spare cleaning pipe is set on the spare sand pipe control valve.
The short tube that shakes out, the inside for the short tube that shakes out is arranged in the utility model at the bottom discharge port of vertical sand warehouse bottom funnel
Metal-ceramic composite tube is set, and metal-ceramic composite tube has very strong abrasion resistance, long service life；In the short tube and vertical of shaking out
Wear-resisting partition is set between formula sand bar bottom funnel, to the bottommost of isolated vertical sand bar bottom funnel, makes vertical sand warehouse bottom
The bottommost of portion's funnel forms vacuum area, avoids the erosive wear of tailings；In the lower section for the short tube that shakes out, main sand pipe is set,
It shakes out and main sand pipe control valve is set between short tube and main sand pipe, put sand channel as normal；It is leaked in vertical sand warehouse bottom
Spare sand developing tube is arranged in the lower end of bucket, to the portion of residual tailings cleaned in the funnel of vertical sand warehouse bottom, avoids tailings solid
Knot is in sand bar bottom；In vertical sand warehouse bottom, spare sand pipe is arranged in the lower end of funnel, and spare put is arranged in spare sand pipe
Spare cleaning pipe is arranged in sandpipe control valve on spare sand pipe control valve, and effect is tailings in the spare sand pipe of cleaning, prevents
Only tailings is fixedly arranged in pipeline, and spare cleaning pipe uses after each sand off.
The utility model is effectively reduced the abrasion of vertical sand warehouse bottom funnel, main sand pipe, avoids tailings leakage,
Environmental pollution caused by tailings leakage is contained；Meanwhile reducing maintenance, maintenance frequency in production, improve production efficiency.This
Utility model structure is simple, easy to maintenance, using reliable, can effectively reduce the abrasion of vertical sand warehouse bottom funnel sand export.
