The invention discloses a kind of flotation device, including sorting groove, mixing tube, mozzle and quill shaft etc., mixing tube is fixed on the middle part of sorting groove vertically, flow-directing shroud is outside mixing tube, it is fixedly connected between mozzle and mixing tube, circulation road under mozzle and mixing tube formation ore pulp, quill shaft is coaxially arranged in the middle part of mixing tube, the air outlet slit of quill shaft is provided with stirring vane on the lower end of mixing tube, and quill shaft outer surface.Flotation function of the present invention makes ore pulp, foaming agent and air fully collide in mixing tube, contact, air can be more full and uniform be distributed in ore pulp, greater number of bubble can be formed, and mozzle causes ore pulp circuitous flow in sorting groove, flow path of the bubble in flotation cell is longer, mineral can be more fully captured, separating effect is more preferable.
Description
Technical field
The present invention relates to mineral floating technical field, more particularly to a kind of flotation device.
Background technology
Foam flotation method is usually used to sort fine particle mineral, relative to tabling, high-gradient magnetic separation and stone
Oil aggregation, bubble flotation has more preferable efficiency and lower cost.The main principle of method for floating is to be based on mineral and slag
The difference of surface chemical property, is carried out mineral and impurity using the hydrophobic nature of mineral particle surface and the hydrophily of slag
Sorting.
In the prior art, generally introduced air into using hollow central siphon in ore pulp, and pass through the stirring of central siphon end
Blade rotational agitation ore pulp, makes air be distributed in ore pulp and forms bubble, and bubble will capture mineral grain, and rise to pulp tank
Top, then the foam containing mineral is hung up by pulp tank by foam scraping machine.In floatation process, can air be distributed to ore pulp
In be influence flotation quality key factor.But flotation device of the prior art, the stirring efficiency of its stirring vane is relatively low, empty
Gas can not in ore pulp full and uniform dispersion, and because stirring causes ore pulp and the upward movement velocity of bubble very fast, bubble and
Mineral time of contact is shorter, and bubble can not fully capture ore particle, and separating effect is poor.
The content of the invention
In view of this, it is an object of the invention to provide a kind of flotation device, air can not be made in ore deposit to solve existing flotation device
Fully dispersed in slurry, bubble and ore pulp time of contact are short, the technical problem of separating effect difference.
Flotation device of the present invention, including sorting groove；
Also include mixing tube, the mixing tube is fixed on the middle part of sorting groove vertically, and sorting is stretched out in the lower end of mixing tube
The bottom of groove；
Also include feed pipe, the port of export of the feed pipe and the lower end of mixing tube are connected by flange, set on feed pipe
It is equipped with foaming agent addition mouth；
Also include mozzle, the flow-directing shroud is fixedly connected outside mixing tube between mozzle and mixing tube, mozzle
Circulation road under ore pulp is formed with mixing tube, and the upper end of mozzle is provided with cover plate；
Also include quill shaft, the quill shaft is arranged on cover plate and is rotatably assorted with cover plate, be sky in the quill shaft
Gas passage, the quill shaft is coaxially arranged in the middle part of the mixing tube, and the air outlet slit of quill shaft is and hollow close to the lower end of mixing tube
It is provided with axle outer surface and the motor that driving quill shaft is rotated is provided with stirring vane, the cover plate；
Also include the foam exclusion pipe of cone, the big end of the foam exclusion pipe is fixedly connected on the cover board, foam row
The small end for squeezing pipe is connected on mixing tube；
Also include being arranged on the annular splicing groove on the outside of sorting groove upper end.
Beneficial effects of the present invention：
Flotation device of the present invention, it in the middle part of sorting groove by setting mixing tube, and ore pulp, foaming agent and air are from mixing tube
During the upward end motion in lower end, motor driving quill shaft is rotated, and the paddle on quill shaft enters to ore pulp, foaming agent and air
Row stirring；Because the length of mixing tube is longer, relative to existing flotation device, ore pulp, foaming agent and the air quilt in mixing tube
The time of stirring is longer, and three can be made fully to collide, contact, and what air can be more full and uniform is distributed in ore pulp, can be formed more
The bubble of multi-quantity, improves separating effect；And the setting of mozzle so that ore pulp in sorting groove first from top to bottom, then from
Under upper circuitous flow, eliminate the problem of existing flotation device stirring movement shortens the bubble floating time, bubble is in flotation cell
In flow path it is longer, it is more with mineral time of contact, can more fully capture mineral, improve separating effect.
Brief description of the drawings
Fig. 1 is the structural representation of flotation device of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As illustrated, the present embodiment flotation device, including sorting groove 1；Also include mixing tube 2, the mixing tube is fixed vertically
The bottom of sorting groove is stretched out in the lower end at the middle part of sorting groove, and mixing tube.
The present embodiment flotation device also includes feed pipe 3, and the port of export of the feed pipe and the lower end of mixing tube pass through flange
Foaming agent addition mouth 4 is provided with connection, feed pipe；Also include mozzle 5, the flow-directing shroud is outside mixing tube, mozzle
It is fixedly connected between mixing tube, circulation road under mozzle and mixing tube formation ore pulp, and the upper end of mozzle is provided with cover plate
7；Connecting plate in the present embodiment between mozzle and mixing tube by spiral shape 6 is connected, and circulation road is spiral flow channel under ore pulp,
Spiral flow channel can extend bubble and mineral time of contact, strengthen the collision of bubble and mineral grain, bubble is fully captured
Ore particle；Certainly in different embodiments, it can also be connected between mozzle and mixing tube by rib, circulation road is then perpendicular under ore pulp
Straight channel, rib can also strengthen the turbulent flow of dirty ore pulp, strengthen the collision of bubble and mineral grain.
The present embodiment flotation device also includes quill shaft 8, and the quill shaft is arranged on cover plate and is rotatably assorted with cover plate, institute
It is air duct to state in quill shaft, and the quill shaft is coaxially arranged in the middle part of mixing tube, and the air outlet slit of quill shaft is close to batch mixing
It is provided with the lower end of pipe, and quill shaft outer surface and the motor that driving quill shaft is rotated is provided with stirring vane 9, the cover plate
