Detailed description of the invention
This utility model is expanded on further below with reference to the drawings and specific embodiments.Should be understood that this
A little embodiments are merely to illustrate this utility model rather than to limit scope of the present utility model.Reading
After this utility model, those skilled in the art are to various amendments of the present utility model and change all to fall
In the application appending claims limited range.
Shown in Fig. 1 according in preferred embodiment of the present utility model, coal slime flotation pretreatment sets
For being installed on vertically arranged black water pipeline.This coal slime flotation pre-processing device includes: casing 2,
Impeller 4, chemicals dosing plant and diversion division 3.Wherein, casing 2 have upper reducer, vertical section and
Lower reducer.Chemicals dosing plant includes medicament source (not shown) and medicament pipe, and medicament pipe has medicament pipe
Vertical section 10 and medicament pipe horizontal segment 6.
It should be appreciated that this coal slime flotation pre-processing device can be arranged at the coal slime water pipe of many trends
Road (such as includes vertical pipe section and horizontal pipe section, it is also possible to include tilted tube section)
Vertical section；Alternatively, this coal slime flotation pre-processing device can also be arranged at the coal being in tilted layout
Muddy water pipeline；Or this coal slime flotation pre-processing device can also be arranged at the black water pipeline of many trends
The horizontal section of (such as including vertical pipe section and horizontal pipe section), if the profit of being capable of
The function that the impulse force impeller produced with black water gravity flow rotates.
The specific works process of the coal slime flotation pre-processing device of the present embodiment is as follows: by 0-0.5mm's
Coal slime enters in pre-processing device, at black water with the black water of water composition through black water pan feeding pipeline 1
Vertical impact effect under, i.e. black water gravity flow speed percussion under, impeller rotates.
Floating agent enters pre-processing device via medicament pipe from medicament source under the effect of the pressure.At blade
Under the stirring action rotated, make black water and medicament by strongly in the narrow gap of tube wall and impeller
Mechanical shearing, centrifugal extruding, clash into and the comprehensive function such as turbulent flow, so that black water and flotation medicine
Agent is sufficiently mixed, and reaches the purpose of coal slurry flotation water pretreatment amount.It addition, along with impeller rotates, coal
Muddy water is thrown to casing inner wall, so that the pressure at impeller central is less than the pressure of periphery, therefore
Medicament is conducive to enter.
As it is shown in figure 1, impeller 4 be provided centrally with rotating shaft 8, rotating shaft 8 can be by such as rolling
Bearing is connected to bearing 9, and bearing 9 is fixed on two shaped steel 5 in decussation.Shaped steel passes through
Welding or the threaded inwall being fixed on the vertical section of casing.Impeller 4 has three, four or six
Blade.It addition, rotating shaft 8 can be connected with electro-motor, in the case of black water flow velocity is relatively low,
Can rotate to realize being sufficiently mixed of black water and medicament by electro-motor impeller.
The top of medicament pipe vertical section is provided with preferably in conical diversion division 3.This diversion division energy
Enough make black water outwards disperse, thus avoid black water that the rotating shaft of impeller central is impacted and shadow
Sound black water is sufficiently mixed with medicament.This diversion division additionally aids medicament and enters, and prevents black water from rushing
Hit the outlet of medicament pipe, adding of retarding agent.This diversion division is along the plane being perpendicular to its center axis
On projected area be arranged to cover the rotating shaft of described impeller central but black water will not be stoped
Impact to the blade of impeller 4.The preferably conical drift angle of diversion division is in 40 ° to 60 °
In the range of.Diversion division can be supported in the top of medicament pipe, stays between diversion division and the outlet of medicament pipe
There is a certain distance, meet medicament and enter the needs of pre-processing device from medicament pipe flow.Substitute as one
Mode, diversion division can also be supported on the shaped steel of the inwall being such as fixed on the vertical section of casing.
In the embodiment show in figure 1, medicament pipe has vertical section and horizontal segment, wherein, medicament pipe
Horizontal segment is through the lower reducer of casing 2；Medicament pipe vertical section is fixed on shaped steel 5 and through bearing
And rotating shaft, or alternatively, medicament pipe horizontal segment is such as by being fixedly welded on the lower reducing of casing 2
Section and vertical section are through bearing and rotating shaft.Vertical section and the horizontal segment of medicament pipe may be integrally formed,
Corner coupling head can also be used to connect for the convenience such as processing and install.Agent outlet is arranged at
Medicament pipe vertical section and be positioned at impeller at a distance above, to ensure that the medicament flowed out stands impeller
Stirring action and be sufficiently mixed with black water.As preferred but nonrestrictive example, medicament goes out
Mouthful can be that at equal intervals or unequal interval is (between preferably etc. along the medicament level circumferencial direction of pipe vertical section
Every) multiple apertures of being distributed.It can be envisaged that can be at the differing heights of medicament pipe vertical section
It is provided with many groups the most equally spaced or multiple holes of being distributed of unequal interval (the most at equal intervals)
Mouthful.The agent outlet that can also imagine can be inclined hole, such as along the circumferencial direction of medicament pipe vertical section
Acclivitous multiple inclined holes of distribution, or drug direction is identical or contrary with the direction of rotation of impeller
Inclined hole.
In this embodiment, casing 2 has upper reducer, vertical section and lower reducer.Wherein,
Upper reducer and lower reducer can be gone out with black water feeding pipe 1 and black water by flange the most respectively
Material pipe 2 connects.The diameter of upper reducer is gradually increased to vertical section from black water feeding pipe 1, thus
The black water contributing to being flowed into by black water feeding pipe 1 is divided in upper reducer and vertical section further
Dissipate, and be sufficiently stirred for, by impeller 4, the space that offer is sufficient in vertical section for black water.Lower reducer
Diameter be gradually reduced to black water discharge nozzle 2 from vertical section, thus contribute to through impeller stirring mixing
Black water and the mixture of medicament converge in lower reducer, thus contribute to black water and medicament
Mixing further.
(being not shown) in another embodiment, agent outlet may be located at the upper change of casing 2
Footpath Duan Chu.Preferably there are the multiple agent outlet being along the circumferential direction distributed, more preferably there is edge
Multiple agent outlet that circumferencial direction is equally spaced.In this embodiment, medicament pipe can
Enter the inside of casing 2, but make medicament send in casing 2 from medicament source diameter by pressure, with
Black water from feeding pipe 1 converges, and stirs realization through impeller 4 at the vertical section of casing 2 and fill
Divide mixing.
