Description
Technical field
The utility model belongs to Tailing thickening technical field, and more particularly to mining and ore dressing field is to selecting tailings
Carry out the flat vertical concentrator of harrow frame fluidisation type of dense dehydration.
Background technology
Mine generally first uses cyclone when the tailing of output in dressing Production Process carries out thickening processing
It is classified.Coarse fraction tailing accumulates formation with higher in the further deposition dehydrating of vertical sand warehouse, the tailing of sedimentation in storehouse
The settled layer of compacted density；Also contain substantial amounts of fine sand grain in spilling water after cyclone classification, vertical sand warehouse can be used to add
Flocculant is further dense, and the tailing of sedimentation is accumulated in storehouse forms the settled layer with higher pressure real density；It is stepless complete
Tailing can also enter vertical sand warehouse, and after addition flocculant is further dense, the tailing of sedimentation accumulates formation in storehouse to be had
The settled layer of higher pressure real density.
No matter keep in as the thick tailings particles after cyclone classification and carried out with vertical sand warehouse, or application vertical sand warehouse bottom
There is higher pressure real density to cause to put the problem of sand is not smooth for dense dehydration, the tailing all deposited after settling.
In the bottom of concentrator, after granule density reaches certain value, the rheological behavior of slurry is special in non-newtonian fluid
Sign, its yield stress are larger, it is difficult to realize smooth discharge.Common concentrator and vertical sand warehouse generally use to be added in orlop portion
Nozzle, realizes that high concentration is arranged using technologies such as high pressure spray water nozzle fluidization pulping, strength pulping or Pneumatic-hydraulic interlocked pulpings
Put.These types of fluidization pulping mode has the drawbacks of many：High pressure spray water nozzle fluidization pulping can cause the tailing of discharge
Concentration reduces；Strength pulping then disturbs the natural subsidence effect of tailing due to bubble rising, reduces dense speed；Air water joins
Dynamic pulping then has the adverse consequences for making the tailings concentration of discharge reduce and disturb tailing natural subsidence to reduce dense speed concurrently.More than
All methods can also increase equipment and the power consumption of high-pressure air source.Seek a kind of pulp consistency that neither reduces does not influence dense effect again
The fluidisation of rate puts sand mode and applies a great problem urgently to be resolved hurrily as vertical sand warehouse.
Common concentrator and vertical sand warehouse polycrystalline substance is mostly cone-shaped, hemisphere build or how cone-shaped.These types knot
The concentrator and vertical sand warehouse of structure are there is complicated, and manufacture difficulty is big, and dischargeable capacity is small, and bottom force-bearing situation difference etc. is asked
Topic.
The flat vertical concentrator of harrow frame fluidisation type described in the utility model uses flat-bottom structure, makes the structure of sand warehouse become
