Description
Technical field
The present invention relates to ore pulp preprocessing technical field before flotation, specifically a kind of compound coal slime flotation high shear pretreatment dress
It puts.
Background technology
Ore pulp pretreatment is essential link in mineral floatation technique, is the elder generation that flotation device obtains good technique index
Certainly condition.The necessity that ore pulp pre-processes before flotation is：1）By floating agent (collecting agent, foaming agent, dispersant and regulator
Deng) disperse and the floating agent of dispersion is well mixed with ore pulp, adsorption of collector target minreal surface raising mineral it is hydrophobic
Property；2）With mineral surfaces physical-chemical reaction, which occurs, for floating agent needs certain action time and condition；3）Floating ore pulp will be entered
Concentration dilution is to zone of reasonableness.As the nature of Mineral Resources in China is to poor miscellaneous thin transformation, valuable mineral disseminated grain size is increasingly
Carefully, composition also becomes increasingly complex, and the ore dressing recovering effect of low-grade subparticle mineral resources is very undesirable always.It improves fine
The organic efficiency of grain ore resource has become economic construction of China, has improved the difficulty that Mineral Resources in China guaranteed extent is badly in need of solution
Topic.Ore pulp preconditioning technique equipment has been difficult to the requirement for meeting complicated mineral products resource high-efficiency flotation recycling before conventional flotation.
At present before flotation in ore pulp pretreatment process, common ore pulp pretreatment mode mainly has：
（1）Mechanical agitation surge tank：Mechanical agitation surge tank is developed by the tank diameter of chemical industry before traditional flotation, by
Realize medicament in the stirring flow field that motor driver drives the one or more blade agitators being mounted on main shaft rotation to generate
Dispersion and the mixing of ore pulp and medicament, and mixed process is strengthened using the baffle on circulation barrel and bucket wall.80 years China's last century
The generation XY series coal paste preprocessors of research and development are after floating agent is introduced into dosing mouth, by upper in stator blade wheel mixer
Medicament suck and disperseed by the parital vacuum that layer blade rotation generates, and ore pulp is sucked by lower floor impeller, in going out for two layers impeller
Cause for gossip shows the mixing of medicament and ore pulp, and since impeller linear velocity is relatively low, the non-polar hydrocarbon oil droplet diameter disperseed is larger,
Dispersion mixing is uneven in coal slurry, increases floating agent dosage.Patent of invention（Application number 200910080897.2）Disclose one
Kind of surface modification pulp mixing machine and its application by mixing cirtern, are sized mixing room equipped with multistage successively in mixing cirtern from stock inlet, adjacent to size mixing
Room is made up of the dish-type blade being fixed on agitating shaft and the partition board being fixed on barrel wall and baffle, by imposing height to ore pulp
Shear environment, the dispersion of raising medicament and its adsorption effect in mineral surfaces increase the hydrophobic difference between mineral, improve
Mineral floatability.The technical solution exists due to there is certain liquid level in mixing cirtern, and pan feeding and floating agent need depended on pressure to feed
The defects of, and the pre- inflation mineralising of ore pulp is can not achieve, it is the improvement to convention stir slot.
（2）Kaskad apparatus for pre-flotation pulp conditioning：Prepare the eighties in last century in the XK series ore pulp that China's coal-mine coal preparation plant begins to use
Device, as patent of invention is entitled " being atomized hybrid coal paste preprocessor "（Application number 201010033384.9）Following skill is issued
Art scheme：It is made of atomization system, upper box body and lower part box three parts, atomization system by main motor, flexible coupling,
Sleeve, haze the compositions such as disk and dosing funnel.Upper box body is atomized workspace for charging and floating agent, has center on the outside of babinet
There are overflow launder in feed chute, the left and right sides.Lower part box is the working space that coal slurry is mixed with floating agent, and the left and right sides is respectively mounted
There are three pieces of upper slides and two pieces of lower skateboards, contour bank item is evenly distributed on each slide plate.In actual use, floating agent is through dosing funnel
And pipeline is flowed into the sleeve above the disk that hazes, and is splashed down in the Pan Zhengmianzhongxinqu that hazes.It is adhered in high-speed rotating disk
One layer of liquid film is formed, is moved under the action of the centrifugal force to plate edge, is droplet by the saw cut of plate edge；Enter in float coal slurry warp
Heart feed chute is assigned in the downflow weir of upper box body both sides, along the wide city waterfall shape overflow in weir, let out fall during and flotation
Medicament droplet meets, some droplet directly drops to first layer upper slide by gravity, later, is mixed with the coal of floating agent
Slurry is continuously jumped up and is mixed by the bank item of upper lower skateboard so that coal slurry is sufficiently mixed with floating agent droplet, until from babinet
Bottom excludes to enter flotation device, and as coal paste preprocessor relatively advanced in field, floating agent dispersion effect is preferable；But
It is found in actual use, since floating agent dispersion effect is only realized by disk rotation of hazing in above structure, generally requires one
A sealed shape babinet for being used to form confined space, to prevent drifting for misty medicament, the formation of closed environment has often resulted in
Mist disk working environment poor the defects of being prone to failure and difficult maintenance maintenance.So as to be brought to execute-in-place and maintenance work
Puzzlement；Since movement of the coal slurry on bank item only being leaned on to realize the mixing of floating agent and coal slurry, mixing intensity is relatively low.
（3）Jet mixer：The water-jetting type coal paste preprocessor that some coal preparation plants promote the use of in China, is substantially pressed
Power ore pulp is projected from nozzle at high speeds, negative pressure is formed in injector, floating agent is consequently inhaled and wraps up in and is rolled onto in jet stream, through waterpower
Impact, shearing are separated into oil droplet, and the mixing of floating agent and coal slurry is realized at ejector trunnion.This mode of sizing mixing mixes by force
Degree is low with the uniformity, and the residence time is short, and there are the defects of medicament and insufficient coal slurry effect.
Ore pulp pre-processing device before flotation of the prior art, mineral and coal slime for regular particle size have preferable effect
Fruit, but for fine-particle minerals, if granularity is less than 200 mesh, content height bring to coarse granule mineral surfaces thin mud the cover and ore deposit
Change efficiency is low, the technical barrier of poor selectivity, bad adaptability, and concentrate organic efficiency is low.
