Abstract
The utility model discloses a flotation assembly, which belongs to the field of ore dressing equipment and aims to overcome the shortcoming that the flotation machine in the prior art has low flotation recovery rate. The flotation assembly comprises flotation machines, a stirring device arranged inside each flotation machine, a false bottom arranged at the bottom of the interior of each flotation machine, and a sleeve arranged at the bottom of each flotation machine and communicated with the false bottom; the stirring device is positioned above the sleeve; the flotation assembly comprises at least two floatation machines, the lower parts of the two adjacent flotation machines are communicated through a tailings tube, the sleeve of one of the two adjacent flotation machines is communicated with the upper part of the other flotation machine through a return tube. The flotation assembly disclosed by the utility model effectively increases the contact time and change between ore slurry and bubbles in the flotation machines, remarkably increases the recovery rate of useful minerals, and increases the economic benefit of a mine.
Description
Technical field
The utility model relates to the preparation equipment field, is specially a kind of flotation unit.
Background technology
At present, China mine is along with suitable ore dressing stone reduces, and the exploitation refractory ore has become inevitable, and the ore-dressing technique of these ores often all needs mog very thin, and selected operation also increases to some extent.Because after mog attenuates; Adopt the collision probability of adhering to of present flotation device valuable mineral particle and bubble to diminish; Perhaps remedy thereby have influence on flotation recovery rate, cause equipment investment to increase the also corresponding increase of operating cost like this through the quantity that increases scavenging flotation machine.
Summary of the invention
In order to overcome the not high deficiency of existing flotation device flotation recovery rate; The utility model aims to provide a kind of flotation unit; This unit adopts scalable to reflux and designs the time of contact and the probability that can effectively prolong interior ore pulp of flotation device and bubble; Can significantly improve the rate of recovery of valuable mineral, improve mine economic profit.
To achieve these goals, the technical scheme that the utility model adopted is: said flotation unit comprises flotation device, is located at the agitating device in the flotation device, is located at the false end of flotation device inner bottom part, the sleeve that is located at the interior bottom of flotation device and is communicated with the said false end; Said agitating device is positioned at this sleeve top; Its design feature is, said flotation unit comprises at least two flotation devices, and adjacent two flotation device bottoms are connected through debris tube, and the sleeve of a flotation device in said adjacent two flotation devices is connected through return duct with the top of another flotation device.
In order to control return flow; Regulate the backflow pulp levels, be provided with adjustable pipe in the said return duct, as entering the mouth when needing the fine-graded ore pulp of backflow can increase adjustable pipe; Adopt screwed connection between adjustable pipe, the coarsely graded ore pulp that needs to reflux can reduce the adjustable pipe inlet.
For the real-time regulated return flow, thereby regulate the backflow pulp levels, be provided with control valve in the said return duct, this control valve is preferably the taper control valve.
In order in whipping process, to form negative pressure better, mineral aggregate is sucked in the sleeve, the distance between the bottom of said agitating device and the sleeve top is preferably 1cm ~ 2cm.
Above-mentioned flotation unit preferably is made up of two flotation devices.
By said structure; After previous flotation device was opened, agitating device began rotation, in sleeve, forms negative pressure; Air also gets in the sleeve under the suction function in external atmosphere pressure and sleeve; Ore pulp gets into first flotation device through the false end sleeve with carry out flotation operation after air mixes, the part valuable mineral is along with bubble floating goes out flotation device, and part valuable mineral owing to well do not mix with bubble passes through next step operation of flotation device entering after the debris tube entering; In order to cross this part mineral is also reclaimed in last flotation device, the return duct that the design of one flotation device is communicated with last flotation device in the back.The ore pulp that back one flotation device includes the part valuable mineral is back at the false end of last flotation device along return duct; And with sleeve in air mix once more and carry out flotation operation; Thereby the time of contact and the probability of ore pulp and air have been improved; Improve the operation recovery of last flotation device, alleviated the burden of subsequent job simultaneously.
Compared with prior art; The beneficial effect of the utility model is: the present invention utilizes the flotation device agitating device to stir the negative pressure that produces, and is connected with sleeve through return duct, and the operation flotation tailing is refluxed; Improved the time of contact of ore pulp and this operation bubble; Thereby improved flotation efficiency significantly, reduced the flotation cost, improved mine economic profit.
Below be that a flotation unit combines accompanying drawing and embodiment that the utility model is done further to set forth with regard to two flotation devices.
Description of drawings
Fig. 1 is the structure principle chart of a kind of embodiment of the utility model.
In the drawings
1, the 10-flotation device; The 2-agitating device; The 3-sleeve; The 4-return duct;
The 5-adjustable pipe; The 6-control valve; The 7-debris tube; The false end of 8-.
The specific embodiment
A kind of flotation unit, as shown in Figure 1, comprise two flotation devices 1,10, in each flotation device 1,10, be equipped with agitating device 2, each flotation device 1,10 inner bottom part is equipped with the false end 8, and the bottom in each flotation device 1,10 is provided with the sleeve 3 that is communicated with the said false end 8; Said agitating device 2 is positioned at this sleeve 3 tops, and the distance between the bottom of this agitating device 2 and sleeve 3 tops is 1cm; Two flotation device 1,10 bottoms are connected through debris tube 7, and the sleeve 3 of a flotation device 1 in said two flotation devices 1 is connected through return duct 4 with the top of another flotation device 10, are provided with adjustable pipe 5 and control valve 6 in the said return duct 4.
Describe for ease, the last flotation device that the present invention defines in two flotation devices 1,10 is the 1# flotation device, and back one flotation device is the 2# flotation device.
After the 1# flotation device is opened; Agitating device begins rotation; In sleeve, form negative pressure, air also gets under the suction function in external atmosphere pressure and sleeve in the sleeve, and 1# flotation device ore pulp carries out flotation operation after getting into sleeve and air mixes through the false end; The part valuable mineral is along with bubble floating goes out flotation device, and the part valuable mineral gets into next operation owing to well do not mix with bubble through debris tube entering 2# flotation device; In order to cross this part mineral is also reclaimed in the 1# flotation device, at 2# flotation device design return duct; The ore pulp that the 2# flotation device includes the part valuable mineral is back to the 1# tank diameter along return duct under the action of negative pressure in 1# flotation device sleeve; And with sleeve in air mix once more and carry out flotation operation; Thereby the time of contact and the probability of ore pulp and air have been improved; Improve the operation recovery of 1# flotation device, alleviated the burden of subsequent job simultaneously.
Present embodiment adopts scalable to reflux and designs the time of contact and the probability that can effectively prolong interior ore pulp of flotation device and bubble, significantly improved the rate of recovery of valuable mineral, has improved mine economic profit.
