Description
Technical field
The utility model belongs to filling in mine technical field, fills system more specifically to a kind of Mine Tailings
System.
Background technique
With the rapid development of our country's economy, it also gradually rises to the demand of mineral resources, dressing plant's concentrate yield increases
While adding, tailing quantum of output is also significantly increased.It establishes Tailings Dam thus to store these tailings, thus also brings various
Risk and harm, such as: occupying a large amount of soils；Seriously affect ecological environment；Tailings Dam is extremely easy to produce security risk, especially
Ore ultra-fine tailings, surface area after ore dressing processing increase, and flowing and leakage of collapsing are easy when stockpiling, causes vegetation deterioration, especially
It is that the natural calamities such as rainy season or earthquake easily cause landslide or mud-rock flow, brings about great losses.It in response to this, be to a large amount of
Tailing is reasonably handled, and the pressure of Tailings Dam is mitigated, it is fully utilized to the filling mining for realizing CHARACTERISTICS OF TAILINGS SAND again.
With the development of filling mining technology, CHARACTERISTICS OF TAILINGS SAND cemented backfilling technology not only can reduce the pressure of Tailings Dam, but also can be with
Realize the recycling to tailing.The filler that mining filling method uses mainly is made of aggregate and cementing agent, usually to divide
Grade tailings, tailings add river sand or crude tailings to be filling aggregate, and after cementing agent is mixed with filling aggregate and water, physics and chemistry occurs
Reaction forms colloid, and filling aggregate is frozen into the Filling Cementation body with some strength.Currently, usually will in the prior art
Tailing magma is delivered to after cyclone classification equipment carries out cyclone classification processing and is delivered to sand warehouse, and adds certain flocculation thereto
Agent carries out flocculating setting, to obtain meeting the filling in mine tailing slurry aggregate of concentration requirement, then by aggregate and gelling agent
It is mixed, forms the obturation with certain fluidity, the goaf of stope is transported to by pipeline self, to reach filling
Purpose.
Wherein, in the prior art when preparing filling in mine tailing slurry aggregate, common flocculant is usually inorganic
Flocculant powder uses after need to being configured to flocculant solution, and being thoroughly mixed for flocculant powder and water body is extremely important, if molten

Operation is carried out, concrete operation step is to add the water of a half volume to dissolving tank, stir to form vortex using blender, will claim
The flocculant crossed again is poured into along the vortex edge that stirring generates, and continues to add water to designated position, and be adjusted to certain concentration, is stirred
Until flocculant powder is completely dissolved.But hand stock cannot be guaranteed moment energy of the flocculant powder in addition of subsequent addition
It is sufficiently mixed with water body, the uneven of adding speed also be easy to causeing flocculant powder largely to agglomerate in water and being not easy stirring
Even, a large amount of flocculant bulk wastes are gathered in dissolution trench bottom, not only cause the wasting of resources, also will affect flocculant production
The stability of process, or even cause line clogging.
Through retrieving, the patent about device for preparing flocculating agent has more disclosure.Such as, Chinese Patent Application No. is
201810556435.2 application case discloses a kind of device for preparing flocculating agent, and the device for preparing flocculating agent of this application includes spiral shell
Revolve transport device, cyclone, agitating device, purifier；Quantitative flocculant powder is evenly sent to by helical conveyer device
Cyclone, forms vortex in cyclone, flocculant powder and water body in advance at the uniform velocity, be sufficiently mixed after, enter back into agitating device and stir
It mixes, thus that can mitigate to a certain degree since hand stock speed is uneven and is not sufficiently mixed bring stirring in advance
The problem of be easy to causeing agglomeration, but being sufficiently mixed for flocculant and water body not can guarantee still using the device of this application.
