Description
Technical field
The utility model belongs to mining technique field, more particularly to a kind of scalable mechanical return water tower.
Background technique
Wet type Tailings Dam accommodates the Tailings Slurry of the production discharge of mine concentration, clear after Tailings Slurry precipitates in Tailings Dam
Clear water need to return to dressing plant's recycling.The return water system of dressing plant's wet type Tailings Dam, current art are generally used by reinforcing bar
Concrete return water tower is delivered to outside Tailings Dam as tailings storage backwater tapered collection structures, and by main return water tunnel, then through library outside
Stilling pond carry out energy dissipating after, dressing plant is returned to by tailings storage backwater tapered pumping plant and completes entire process water reuse process.
Existing armored concrete return water tower needs first to design an armored concrete according to the design storage capacity height of Tailings Dam
Drain off floodwaters tower, which will exceed Tailings Dam design liquid level, general minimum ten meters of tower height even hundreds of meters high；Steel drum is along short transverse
It is equidistantly evenly distributed with backwater hole, with the deposition of ore pulp in Tailings Dam, dry beach constantly increases bottom storehouse and constantly raises, to avoid mud etc.
Solid enters return water tower, needs to be manually entered the closure operation that bottom backwater hole is carried out in Tailings Dam.
There are the following problems for armored concrete return water tower used by current art:
Firstly, the final water level of Tailings Dam design is higher, and general minimum ten meters or even hundreds of meters, using armored concrete material
The return water tower cost of matter is higher；And armored concrete return water tower also has the processing of ground since steel drum is higher and load is huge
Extremely harsh requirement, also improves capital expenditure.
Secondly as water level and drop outside library are very big in library, the Tailings Dam collected by existing armored concrete return water tower is clear
Clear water kinetic energy is very big, and the existing armored concrete tower that drains off floodwaters cannot independently be completed at the same time the function of water intaking and energy dissipating, needs leading back
Stilling pond is arranged in water tunnel end, just can enter tailings storage backwater tapered pumping plant conveying after carrying out energy dissipating.The stilling pond added also increases
The investment of engineering.
Again, armored concrete return water tower be different from tailing dam, tailing dam can use tailing deposit the dry beach to be formed into
Row is built a dam stage by stage, and armored concrete return water tower then needs one-stage completion, and by the requirement of concrete curing phase, concrete needs to divide
Layer casting, construction period is very long, armored concrete drain off floodwaters tower construction time become Tailings Dam construction bottleneck.
Further more, armored concrete return water tower since backwater hole is fixed, can not be selected according to water quality superiority and inferiority in Tailings Dam
Property return water.When primary water is because of the reasons water quality deterioration such as heavy rain or mountain torrents in Tailings Dam, return water can not be suspended, so poor-quality water or
It is used into dressing plant, leads to that ore-dressing technique is caused centainly to interfere；Or enter natural water body by stilling pond overflow, it pollutes
Environment.
The most importantly backwater hole that existing armored concrete return water tower steel drum is arranged along short transverse, in Tailings Dam
The deposition of ore pulp, dry beach constantly increase bottom storehouse and constantly raise, and need to be manually entered the closure that bottom backwater hole is carried out in Tailings Dam
Operation.Backwater hole is blocked to need operation to be assisted simultaneously with underwater on staff's water surface, by log in backwater hole band water
Wedge blocks backwater hole.Work flow is complicated, personnel are exposed under high-risk environment, exists compared with high safety hidden danger, and in Tailings Dam
Increasing in the length of service with mud position needs successively to block always.Increase the security risk of operating personnel and the operation and maintenance in dressing plant
Spending.
Thus, it is necessary to develop the wet type that a kind of construction is rapid, cost is relatively low, return water is controllable, service life is non-maintaining
Tailings Dam primary water return water facility.

1 bottom of the tower body covering of scalable mechanical return water tower is fixed on 17 upper end of tunnel face by the horizontal tunnel mouth 17 of water tunnel 16,
Along 17 peripheral sealing of tunnel face, when having water in Tailings Dam 19, float water intake 2 in Tailings Dam 19 under the buoyancy of water,
As SEA LEVEL VARIATION changes height, when water level increases, float water intake 2 drives the steel drum of tower body 1 from inner under buoyancy
Layer is successively pulled up to outer layer, and when the water level descends, float water intake 2 follows the steel drum of water level decreasing drive tower body 1 from outer
Layer arrives the layer-by-layer retracted downward of inner layer.Without keeping the position of intake more than water level when return water；The utility model it is worked
Journey are as follows: when the water quality in Tailings Dam 19 is after the precipitating of certain time, and water quality meets requirement and needs using return water,
Water pump water delivery into float portion in the float water intake of the mechanical return water tower of remote controlled retractable, to increase float water intake 2
Overall weight, so that float increases draft under the effect of gravity, the position of intake is gradually decrease to water level hereinafter, water intaking
Mouthful it is in floodage, stops water pump and keep 2 draft of float water intake, the water in Tailings Dam 19 is under the effect of gravity from taking
The mouth of a river is injected in the steel drum of 1 innermost layer of tower body, flows into next layer of steel drum from the through-hole of steel drum bottom, so in layer toward dirty
Until outermost layer steel drum, energy dissipating is buffered layer by layer, guarantees its hydrostatic head continuously less than 9m, then from the logical of outermost layer steel drum bottom
Hole flows to return water tunnel 16, then flows into pond 18 along return water tunnel 16 for taking, and keeps intake in Tailings Dam with float
Higher level, avoid be introduced into Tailings Dam compared in low water level containing the water that mud is more；After the completion of return water, with pump handle float
Water in cavity is released, and the draft of float water intake 2 is reduced, so that intake goes back up to the water surface or more stopping again and takes
Water.Water quality deterioration in library, the then water being remotely controlled in emptying water pump float portion make at intake caused by Tailings Dam is because of reasons such as heavy rains
In vacant state, stops return water, carry out return water again when water quality is met the requirements.A kind of construction can be provided using the utility model
Rapidly, the wet type Tailings Dam primary water return water facility that cost is relatively low, return water is controllable, service life is non-maintaining.
