Description
Technical field
The present invention relates to mining filling system, particularly a kind of auxiliary last mortar for filling in mine collect buffering to
Material device and method, it is achieved last mortar collects mixing, decompression energy dissipating, steady feed lenitively.
Background technology
The tailings feed-type of current filling system for being fed directly to the last mortar of filling from the last mortar selecting factory to come
Concentrate and in storage facility (sand storehouse or deep wimble thickener), mix with flocculant, accelerating sedimentation and the concentration of tailings.This
There is certain problem in feed-type: the last mortar coming from ore dressing plant concentration basin underflow conveying exists certain overbottom pressure, directly enters
Enter last mortar concentration and storage facility can produce bigger impulsive force, the sedimentation of interference tailings and concentrated effect, strengthen flocculant
Addition, increase operation cost, affect tailings concentration and the overflow water quality of storage facility simultaneously.
For the filling system in extensive cut and fill mine, current technical experience both domestic and external is still shallow, how with reference to little
Scale cut and fill mine is designed and builds, and exists in place of number of values obtains Optimal improvements.Extensive filling method is opened
For mining mountain, the problem bigger in order to solve the next last mortar flow of ore dressing plant concentration basin underflow conveying, generally use a plurality of
The last mortar that the mode that pipeline is divided equally is delivered to filling concentrates and storage facility.But, in order to ensure the sedimentation concentration of tailings
Effect, last mortar concentrates and the feed pipe of storage facility generally uses single pipe, and last mortar could enter after must collecting mixing
Last mortar concentrates and storage facility.Therefore, how before ensureing not change the Specifeca tion speeification such as total flow and mass concentration
Put realize last mortar collect, mix and buffer particularly critical, be also the application put forth effort solve problem.
Content of the invention
It is an object of the invention to provide a kind of being capable of to mix and decompression energy dissipating collecting of last mortar, make last mortar put down
Steady collecting to the last mortar concentration of filling and the last mortar of storage facility feed lenitively buffers charging gear and method.
The technical scheme is that
A kind of last mortar collects buffering charging gear, it is characterised in that: include the casing with top board and base, be fixed on
It the water conservancy diversion collection bucket that downwardly extends below roof box and along the short transverse of casing, is fixed on above cabinet base and along casing
Short transverse upwardly extending mixing overflow buffer barrel and water conservancy diversion collection bucket inner space feed pipe, be located at wall box
The discharge nozzle of bottom and the diagrid being located in water conservancy diversion collection bucket, the upper edge of described mixing overflow buffer barrel is not less than water conservancy diversion collection bucket
Lower along position, and mixing overflow buffer barrel bucket footpath be more than water conservancy diversion collection bucket bucket footpath, between the two formed annular overfall, described
Form loop buffer space between mixing overflow buffer barrel and wall box.
Above-mentioned last mortar collects buffering charging gear, the quantity at least two of described feed pipe, is individually fixed in case
It above the top board of body or run through the sidewall of casing and water conservancy diversion collection bucket is fixed, is arranged in parallel between each feed pipe or angled cloth
Put.
Above-mentioned last mortar collects buffering charging gear, and the top board center of described casing is provided with unlimited maintenance and observes
Hole, simultaneously works as the effect of exhaust decompression.
Above-mentioned last mortar collects buffering charging gear, and the side wall upper part of described casing is provided with the overflow with its inner space
Pipe.
Above-mentioned last mortar collects buffering charging gear, in described casing, water conservancy diversion collection bucket and mixing overflow buffer barrel
Heart line overlaps.
A kind of last mortar that have employed above-mentioned device collects buffering feeding method, it is characterised in that: from ore dressing plant
Last mortar is entered in water conservancy diversion collection bucket by feed pipe, filters out direct current extremely mixing overflow buffer barrel after bulk waste residue through diagrid
In, mixing overflow buffer barrel in collect mixing after by annular overfall overflow to casing with mix between overflow buffer barrel
In loop buffer space, finally flowed out by discharge nozzle, giving to last mortar thickener storage facility of steady mitigation.
The invention has the beneficial effects as follows:
1st, on the premise of not changing the Specifeca tion speeification such as total flow and mass concentration, it is achieved that last mortar collect and
Mixing, makes last mortar become more steadily to relax, beneficially subsequent treatment；
2nd, serve the effect of decompression energy dissipating, reduce newly supplied last mortar and tailings is concentrated and existing in storage facility
The impulsive force of last mortar, makes the pan feeding of last mortar become more steadily to relax；
3rd, considerably reduce tailings to concentrate and the consumption of flocculant in storage facility, save operation cost；
4th, the overflow water quality of tailings concentration and storage facility, more conducively later stage process are significantly improved.
