Abstract
The utility model discloses a kind of slurry concentrating dehydration device, including a cyclone, one concentrator, one high concentration agitator, the cyclone are respectively connected to the concentrator and the high concentration agitator, and the cyclone is classified and is concentrated to ore pulp, hydrocyclone sand flows automatically to the high concentration agitator, cyclone overflow flows automatically to the concentrator and is concentrated, thickener underflow is sent mixed to high concentration agitator with hydrocyclone sand after obtain ore pulp of the concentration 65% or more.The utility model structure is simple to operation, applies it to the thickening of all kinds of ore pulps in mine, can effectively eliminate the vicious circle and its influence of micro-size fraction material in mineral aggregate concentration process.
Description
Technical field
The utility model belongs to mineral manufacture field, in particular to a kind of device of slurry concentrating dehydration is suitable for mine
All kinds of ore pulps in mountain carry out thickening.
Background technique
When underground mine carries out underground filling using tailing, due to tailings concentration it is very low (it is low less than 10%, it is high not yet
Cross 30% or so), it is necessary to thickening is carried out to it, to reach concentration needed for underground filling, meanwhile, also realize mine quick
Recycling water utilization.
Traditional filling process is that the tailing ore pulp of dressing plant's output is raised using sand pump and sent to concentrator, is concentrated into underflow
Concentration 40% or so, then raised and given to Filling Station into sand warehouse with sand pump, sedimentation concentration, finally makes pulp density reach 65% or more again
When, then mixed with additives such as gelling agents, carry out underground filling；Concentrator is returned into sand warehouse overflow water.And in Filling Station into sand
During carrying out sedimentation concentration again in storehouse, easily there is Filling Station into sand warehouse overflow water and run mixed phenomenon, run in mixed overflow water
Subparticle can always in the process constantly circulation, and constantly deteriorate effect of settling, even if using flocculant strengthen settle,
It cannot be completely eliminated its influence.
Summary of the invention
The purpose of the utility model is to provide a kind of slurry concentrating dehydration devices, are applied to the dense of all kinds of ore pulps in mine
Contracting dehydration solves subparticle bring in slurry concentrating dehydration and settles deterioration problem.
The slurry concentrating dehydration device of the utility model, it is characterised in that including a cyclone, a concentrator, a high concentration
Agitator, the cyclone are respectively connected to the concentrator and the high concentration agitator, and the cyclone carries out ore pulp
Classification and concentration, hydrocyclone sand flow automatically to the high concentration agitator, and it is dense that cyclone overflow flows automatically to the concentrator progress
Contracting, thickener underflow is sent mixed to high concentration agitator with hydrocyclone sand after obtain ore pulp of the concentration 65% or more.
The further technical solution of the utility model is:
Flocculant is added in the concentrator.
The eddy flow machine sand setting concentration is not less than 70%, and yield is about 2/3.
55% or more the thickener underflow concentration.
The utility model is classified and is concentrated using cyclone first, and thickness grading is not only realized, while
Mineral aggregate concentration may be implemented.Fine-graded cyclone overflow is concentrated using concentrator for the utility model, and when concentration can add
Suitable flocculant accelerated sedimentation.High concentration agitator is arranged in the utility model, realizes the mixing of thick fine fraction concentration ore pulp,
To obtain the ore pulp to be filled of 65% or more concentration.The utility model structure is simple to operation, eliminates Filling Station into sand warehouse
Overflow water returns, and applies it to the thickening of all kinds of ore pulps in mine, can effectively eliminate micro-size fraction in mineral aggregate concentration process
The vicious circle and its influence of material, while can simplify filling process process.
The utility model can be widely applied to all kinds of slurry concentrating dehydrations in mine, be particularly suitable for mine tailing filling system
System, has certain popularization and reference to the other industry for carrying out thickening or field is needed also, has and pushes away well
Wide application prospect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of tailing slurry concentrating dehydration device.
In figure: 1-- tailings pump pond；2-- tailing sand pump；3-- cyclone pumps pond to mine；4-- cyclone is pumped to mine
5-- cyclone；6-- concentrator；7-- high concentration agitator.
Specific embodiment
In order to better understand the utility model, the content of the utility model is furtherd elucidate below with reference to embodiment, but
The utility model is not limited solely to embodiment.
As shown in Figure 1, the utility model is applied to the thickening that tailings mixes in filling in mine, tailing slurry concentrating
Dehydration device include tailings pump pond 1, tailing sand pump 2, cyclone to mine pump pond 3, cyclone give mine pump 4, cyclone 5, concentrator
6, high concentration agitator 7, wherein cyclone 5 is respectively connected to concentrator 6 and high concentration agitator 7.
The tailing ore pulp of dressing plant's output by broken, ore grinding and after sorting, is pooled in tailings pump pond 1, uses CHARACTERISTICS OF TAILINGS SAND
Pump 2, which is raised, to be sent to cyclone in mine pump pond 3；Tailing ore pulp is raised to mine pump 4 with cyclone and is sent to cyclone 5, carries out control point
Grade and concentration.
Control 5 sand setting amount of cyclone accounts for about the 2/3 of tailing total amount, and controls sand setting concentration not less than 70%.It is total to account for about tailing
Amount 2/3 hydrocyclone sand flow automatically to high concentration agitator 7, account for about tailing total amount 1/3 cyclone overflow then flow automatically to it is dense
Machine 6 is concentrated.Suitable flocculant is added in concentrator 6 -- polyacrylamide, to accelerate microfine in cyclone overflow
Grade sedimentation.55% or more thickener underflow concentration is controlled, thickener underflow is raised with sand pump and is sent to high concentration agitator 7.
The mixing of hydrocyclone sand and thickener underflow is realized in high concentration agitator 7, concentration reaches 65% or more.
The addition filling gelling agent in high concentration agitator after mixing well, is implemented to fill to underground goaf.
