The invention discloses a kind of flotation devices, including sorting groove, mixing tube, diversion pipe and hollow 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 diversion pipe and mixing tube, diversion pipe and mixing tube form circulation road under ore pulp, and hollow shaft is coaxially arranged in the middle part of mixing tube, the air outlet slit of hollow shaft is provided with stirring blade close to the lower end of mixing tube, and on hollow shaft outer surface.Flotation function of the present invention makes ore pulp, foaming agent and air sufficiently 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 diversion pipe makes 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, in particular to a kind of flotation device.
Background technique
Foam flotation method is usually used to sorting fine particle mineral, relative to tabling, high-gradient magnetic separation and stone
Oil aggregation, bubble flotation have better efficiency and lower cost.The main principle of method for floating is 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, it generallys use hollow central siphon to introduce air into ore pulp, and passes through the stirring of central siphon end
Blade rotational agitation ore pulp, is distributed to air 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 an important factor for.But flotation device in the prior art, the stirring efficiency of stirring blade is lower, empty
Gas cannot in ore pulp full and uniform dispersion, and due to stirring so that ore pulp and bubble move upwards fast speed, bubble and
Mineral time of contact is shorter, and bubble cannot sufficiently capture ore particle, and separating effect is poor.
Summary of the invention
In view of this, air cannot be made in mine to solve existing flotation device the object of the present invention is to provide a kind of 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；
It further 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 slot；
It further include feed pipe, the outlet end of the feed pipe and the lower end of mixing tube pass through flanged joint, set on feed pipe
It is equipped with foaming agent adding mouth；
It further include diversion pipe, the flow-directing shroud is fixedly connected between diversion pipe and mixing tube outside mixing tube, diversion pipe
Circulation road under ore pulp is formed with mixing tube, and the upper end of diversion pipe is provided with cover board；
It further include hollow shaft, the hollow shaft is set on cover board and is rotatably assorted with cover board, is sky in the hollow shaft
Gas channel, the hollow shaft is coaxially arranged in the middle part of the mixing tube, and the air outlet slit of hollow shaft is and hollow close to the lower end of mixing tube
It is provided with stirring blade on axis outer surface, the motor of driving hollow shaft rotation is provided on the cover board；
It further 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 diversion pipe；
It further include the annular splicing groove being arranged on the outside of sorting groove upper end.
Beneficial effects of the present invention:
Flotation device of the present invention, by being arranged mixing tube in the middle part of sorting groove, ore pulp, foaming agent and air are from mixing tube
During the upward end motion in lower end, the rotation of motor driven hollow shaft, paddle on hollow shaft to ore pulp, foaming agent and air into
Row stirring；Since 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 sufficiently 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 diversion pipe 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.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of flotation device of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown, the present embodiment flotation device, including sorting groove 1；It further include mixing tube 2, the mixing tube is fixed vertically
At the middle part of sorting groove, and the bottom of sorting groove is stretched out in the lower end of mixing tube.
The present embodiment flotation device further includes feed pipe 3, and the outlet end of the feed pipe and the lower end of mixing tube pass through flange
It connects, is provided with foaming agent adding mouth 4 on feed pipe；It further include diversion pipe 5, the flow-directing shroud is outside mixing tube, diversion pipe
It is fixedly connected between mixing tube, diversion pipe and mixing tube form circulation road under ore pulp, and the upper end of diversion pipe is provided with cover board
7；It being connected between diversion pipe and mixing tube by the connecting plate of spiral shape 6 in the present embodiment, circulation road is spiral flow channel under ore pulp,
Spiral flow channel can extend bubble and mineral time of contact, reinforce the collision of bubble and mineral grain, bubble is enable sufficiently to capture
Ore particle；Certainly in different embodiments, can also be connected by rib between diversion pipe and mixing tube, circulation road is then perpendicular under ore pulp
Straight channel, rib can also enhance the turbulent flow of dirty ore pulp, reinforce the collision of bubble and mineral grain.
The present embodiment flotation device further includes hollow shaft 8, and the hollow shaft is set on cover board and is rotatably assorted with cover board, institute
It states for air duct in hollow shaft, the hollow shaft is coaxially arranged in the middle part of mixing tube, and the air outlet slit of hollow shaft is close to mixing
