Detailed description of the invention
For ease of understanding, here in connection with Fig. 1-4, specific embodiments of the invention are made described further below:
The particular make-up part of the present invention, is divided into several big module, including: thickener body 10, pan feeding pipeline drive rabbling mechanism 30, downflow weir 20 and hydraulic pressure rake lifting device 50.It is been described by one by one below:
1, thickener body
Thickener body is the essential structure of thickener, for the volume that the flocculating sedimentation of black water is enough with clarification offer.
2, pan feeding pipeline
Ore pulp is carried by ore pulp pipeline 42, is successively provided with medicament pipeline 43 and pipe-line mixer 44 on the pipeline of pulp conveying;Medicament pipeline 43 inserts the horizontal fragmentation axis degree of depth of ore pulp pipeline 42, and agent outlet direction is contrary with ore pulp direct of travel, it is achieved the feeding and mix with the preliminary of ore pulp of medicament;Pipe-line mixer 44 is set subsequently on the vertical fragmentation of ore pulp pipeline 42, it it is the preliminary mixing in order to realize medicament further, why arranging pipe-line mixer on vertical fragmentation to be because this mode and arrange that the fluid turbulence degree than arranging generation on horizontal fragmentation is higher, mixed effect is better.
High pressure desilting pipeline 41 is one group of emergent and spare duct, when normally producing, the valve of this pipeline is to close, when the aobvious number of the Pressure gauge 40A on main pipeline 40 is gradually increased, the aobvious number of pressure display instrument table 37 on shell body 31 top is gradually increased, according to scene, engineers and technicians judge that " pressure rake " phenomenon occurs in the harrow frame of thickener, and single hydraulic pressure proposes rake operation when cannot mention harrow frame 54, high pressure desilting pipeline 41 starts action, utilize the high-lift current of this Pipeline transport, water under high pressure goes out from the nozzle 36A jet of bubbler 36, that impacts above harrow frame 54 is material bed, reduce material bed concentration, assist to carry completing of rake operation.
3, rabbling mechanism is driven
Ore pulp enters the center feeding mouth of thickener with preliminary scattered medicament from the main pipeline 40 of pan feeding, how further to realize the Homogeneous phase mixing of medicament and ore pulp, reduce pan feeding process to the impact of steady flow condition in thickener simultaneously, be the purpose driving rabbling mechanism 30 to arrange.The driving turbine 33 utilized in the main pipeline 40 of ore pulp pan feeding in the drive force rotating shaft 34 of ore pulp rotates, and then the diversion mixing impeller 35 of drive shaft 34 and rotating shaft lower end rotates, ore pulp and medicament are stirred together under effect what drive turbine 33 and diversion mixing impeller 35, mix homogeneously, this design, by the energy in pulp conveying process, is changed into the mechanical energy of medicament mix and blend, both dispersion and the mixing of medicament had been realized, reduce again energy consumption, there is maintenance capacity low, the feature that medicine consumption is low;Meanwhile, consume the unnecessary kinetic energy of ore pulp, reduce pan feeding to the impact of steady flow condition in thickener body;Additionally, be also connected with reductor 32 in rotating shaft 34, to guarantee to drive stirring structure 30 when meeting medicament mix and blend requirement, operate with the slow-speed of revolution, reduce the impact on steady flow condition.The effect of the horn mouth design of shell body 31 is by the ore pulp of horizontal movement, progressively guide into and move both vertically, bubbler 36 is set bottom shell body, is dispersed in thickener body along peripheral direction when being conducive to ore pulp to gush out, provide good environment for follow-up sedimentation clarification.Additionally, during thickener work, the concentration of the concentration nitride layer in thickener body is difficult to monitoring in real time, this equipment arranges pressure sensor device 36B in the nozzle 36A of bubbler 36, when concentration nitride layer concentration raises, pressure sensor device 36B pressure raises, it is simple to engineers and technicians quickly understand the change of bed in thickener timely, and take measures.
4, hydraulic pressure rake lifting device
The effect of hydraulic pressure rake lifting device 50 is when " pressure rake " phenomenon occurs in harrow frame 54, quickly mentions harrow frame, it is to avoid harrow frame " is killed ", causes production accident, causes complete plant shutdown;This product is provided with " pressure rake " early warning signal feedback, such as pressure sensor device 36B and Pressure gauge 40A, it is prevented that the generation of " pressure rake " phenomenon;After " pressure rake " phenomenon produces, hydraulic pressure rake lifting device 50 and high pressure desilting pipeline 41 cooperating, it is possible to solve rapidly " pressure rake " phenomenon, return to normal production.
To sum up, the structure of the present invention and working mechanism take into full account the technology characteristics that slurry water flocculation settles, and thickener body flow field is stable, and coal slime flocculating sedimentation is effective, and overflow water clarity is high, and reagent consumption amount is low, prevent and quick solution harrow frame " pressure rake " phenomenon.Whole concentration operation saves medicament more than traditional concentration and settlement equipment, has higher thickening efficiency, works relatively reliable stable, and production cost reduces also extremely obvious.
