As depicted in figs. 1 and 2, filling slurry Preparation equipment provided by the invention is used for the method for mining by the way of filling, including sets successively
The tailings paste dehydrating device 10 and concrete mixing plant 20 set.
Wherein, there are many structure types of tailings paste dehydrating device 10, such as:Directly it is dehydrated using cyclone, or
Person directly uses filter press press filtration.
Concrete mixing plant 20 is by stirring host, material weighing system, material-transporting system, storing material system, control
The construction material manufacturing equipment of five big composition system of system processed and other affiliated facilities composition.It is few with Dose times, production effect
The advantages that rate is high.
In the present embodiment, the moisture in last mortar is sloughed by tailings paste dehydrating device 10 and obtains siccative tailings, then
Dry tailings and dry aggregate are sent respectively to the different feed bins of concrete mixing plant 20 again, matched according to setting, concrete stirring
Stand 20 voluntarily can carry out weighing dispensing by the material weighing system and control system of itself to each dispensing, then concentrate conveying
Into blender, a variety of siccatives are unified to be measured, concentrates addition, so that proportion speed, easily manipulation, and then can obtain accurately
Filling slurry concentration.
What filling slurry Preparation equipment provided in this embodiment can be generated has the beneficial effect that:
First, concrete mixing plant 20 voluntarily carries out each dispensing by the material weighing system and control system of itself
Dispensing is weighed, the unified of each siccative is measured to realize, concentrates addition, metering adding procedure is easy to control, so as to carry
The precision of high mixture ratio, and then the fluctuation of concentration of filling slurry can be avoided big.
Second, Filling Station carries out preparing filling slurry using concrete mixing plant 20, and the metering of concrete mixing plant collection is stirred
The functions such as mix, store and transport in one, it is compact-sized, it is powerful, it is 20 complete equipment modularization of concrete mixing plant, complete
Change, without being built in the large scale equipments such as Filling Station setting concentrator (or sand warehouse), cement bin, stirring system and filling workshop or structure
Object, then the floor space of filling slurry Preparation equipment provided in this embodiment reduce significantly, the construction period greatly shortens, investment at
Originally it is greatly lowered.
Third, the superfine tailings (being less than 200 mesh cumulative levels up to 90% or more) in mine, filling slurry concentration is low, by force
The problem of degree is also low, high sulfur content height (20% or more content), later stage strength of filling mass will appear disintegration.And through this embodiment
The filling slurry Preparation equipment of offer can obtain the stirring body of coarse aggregate and tailings, and coarse aggregate can dilute in slurry indirectly
The content of S avoids carrying out S choosings to tailings and filling cost being caused to increase to avoid influences of the S to intensity.
4th, due to the addition of coarse aggregate, the grade composition of filling slurry on the whole changes, and Filling density is high;Add
Filling slurry intensity after overstriking aggregate can greatly improve, and filling cement-sand ratio can substantially reduce, and cement cost reduces, final to fill
Cost substantially reduces.
As shown in Figures 2 to 5, on above-described embodiment basis, further, tailings paste dehydrating device 10 includes successively
Cyclone 11, feed pipe 12 and the setting pot 13 of connection;One end of setting pot 13 is provided with discharge opening 131, at discharge opening 131
It is provided with filter device 14.
In the present embodiment, by low concentration tailing slurry (after a concentration of 15%~20%) is pumped to cyclone 11, cyclone
11 first walk the ultra-fine tailings cyclone classification of good water-retaining property, flow down coarse granule tailings.11 overflow low concentration last mortar of cyclone
It is pumped to Tailings Dam, underflow high concentration tailings (moisture content 30% or so) is flow to certainly in setting pot 13.
Last mortar enters setting pot 13 after the dehydration of 11 level-one of cyclone, and a part of tailings in last mortar sinks in pond
It forms sediment, a part is flowed away with water to discharge opening 131, and when by discharge opening 131, which is stopped by filter device 14, stays in
In setting pot 13, last water is discharged by setting pot 13.Moisture content is obtained in setting pot 13 in 12% tailings below, tail at this time
Sand can show very strong grittiness, and tailings is more loose, and such filling is stirred more uniformly after gathering materials into stirring system,
Cement-sand ratio proportioning is more accurate, and boulder yield is low in filling slurry.
Tailings paste dehydrating device provided in this embodiment is dehydrated using cyclone classification and setting pot 13 is dehydrated, and low energy consumption, at
This is low.And be dehydrated by two-stage grade, dehydration rate higher, dehydrating effect is good, and tailings water content is few, disclosure satisfy that later stage stirring needs
It wants.
Wherein, there are many structure types of filter device 14, such as:Filter device 14 includes filter cloth or filter device
14 include strainer, or including strainer and filter cloth.
The shape of setting pot 13 can be a variety of, such as:Round, ellipse, triangle or abnormity etc., are preferably adopted
With rectangle, compound with regular structure facilitates construction, and later stage forklift is facilitated to carry out shovel sand to the tailings in setting pot 13.
The material of setting pot 13 can be a variety of, such as:Stone, cement or metal etc..
It can also be more than two multiple that setting pot 13, which can be one,.When setting pot 13 is multiple, multiple sand settings
Shape, the size in pond 13 can be all different, can part it is identical, can with all same, can according to particular condition in use come
Personal settings are carried out to each setting pot 13.
When setting pot 13 is multiple, multiple setting pots 13 are connected to feed pipe 12, can be mutual with multiple setting pots 13
Connection, one of them is connected to feed pipe 12;It is preferred that multiple setting pots 13 are mutual indepedent, each setting pot 13 is directly
It is connected to feed pipe 12, this structure can mutually flow to avoid last mortar between setting pot 13, de- to further increase
Water effect, further increases dehydration efficiency.
Preferably, as shown in Figure 1, setting pot 13 is three, three setting pots 13 are respectively the first setting pot 1301, second
