Embodiment
The present invention is expanded on further below with reference to the drawings and specific embodiments.It should be understood that these realities
Example is applied to be merely to illustrate the present invention rather than to limit the scope of the present invention.Reading the present invention's
Afterwards, various modifications and change of the those skilled in the art to the present invention fall within the right appended by the application
In claim limited range.
Shown in Fig. 1 according in a preferred embodiment of the present invention, coal slime flotation pre-processing device peace
Loaded on vertically arranged coal slime waterpipe.The coal slime flotation pre-processing device includes：Casing 2, impeller
4th, chemicals dosing plant and diversion division 3.Wherein, casing 2 has upper reducer, vertical section and lower reducing
Section.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 the coal slime flotation pre-processing device can be arranged at the coal slime water pipe moved towards more
Road (such as, including vertical pipe section and horizontal pipe section, can also include tilted tube section)
Vertical section；Alternatively, the coal slime flotation pre-processing device can also be arranged at the coal being in tilted layout
Muddy water pipeline；Or the coal slime flotation pre-processing device can also be arranged at the coal slime waterpipe moved towards more
The horizontal section of (such as including vertical pipe section and horizontal pipe section), as long as profit can be realized
The function that the impulse force impeller produced of being flow automatically with black water rotates.
The specific work process of the coal slime flotation pre-processing device of the present embodiment is as follows：By 0-0.5mm's
The black water that coal slime is constituted with water enters in pre-processing device through black water pan feeding pipeline 1, in black water
Vertical impact effect under, i.e. black water gravity flow speed percussion under, impeller is rotated.
Floating agent is under the effect of the pressure from medicament source enters pre-processing device via medicament pipe.In blade
Under the stirring action of rotation, make black water and medicament in the narrow gap of tube wall and impeller by strong
Mechanical shearing, centrifugation extruding, hit 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.In addition, as 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 shown in figure 1, impeller 4 is provided centrally with rotating shaft 8, rotating shaft 8 can be for example, by rolling
Bearing is connected to bearing 9, and bearing 9 is fixed on two shaped steel 5 in right-angled intersection.Shaped steel passes through
The inwall of casing vertical section is fixed in welding or threaded connection.Impeller 4 has three, four or six
Blade.In addition, rotating shaft 8 can be connected with electro-motor, in the case where coal slime water flow velocity is relatively low,
It can be rotated realize being sufficiently mixed for black water and medicament by electro-motor impeller.
The diversion division 3 preferably in cone is provided with the top of medicament pipe vertical section.The diversion division energy
Enough black water is set outwards to disperse, so as to avoid rotating shaft of the black water to impeller central from impacting and shadow
Ring being sufficiently mixed for black water and medicament.The diversion division additionally aids medicament entrance, prevents black water from rushing
The outlet of medicament pipe is hit, retarding agent is added.The diversion division along perpendicular to its center axis plane
On projected area be arranged to cover the rotating shaft of the impeller central but black water will not be prevented
Impact to the blade of impeller 4.Preferably the 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, be stayed between diversion division and the outlet of medicament pipe
Have a certain distance, meet medicament from medicament pipe flow into pre-processing device the need for.It is used as one kind replacement
Mode, diversion division, which can also be supported in, to be for example fixed on the shaped steel of the inwall of casing vertical section.
In the embodiment show in figure 1, medicament pipe has vertical section and horizontal segment, wherein, medicament pipe
Horizontal segment passes through the lower reducer of casing 2；Medicament pipe vertical section is fixed on shaped steel 5 and passes through bearing
And rotating shaft, or alternatively, lower reducing of the medicament pipe horizontal segment for example by being fixedly welded on casing 2
Section and vertical section pass through bearing and rotating shaft.The vertical section and horizontal segment of medicament pipe may be integrally formed,
Corner coupling head connection can also be used for the convenience for example processed and installed.Agent outlet is arranged at
Medicament pipe vertical section and above the impeller at a certain distance from, impeller is subjected to the medicament for ensureing outflow
Stirring action and be sufficiently mixed with black water.As preferred but nonrestrictive example, medicament goes out
Mouthful can be along the level circumferencial direction of medicament pipe vertical section at equal intervals or unequal interval is (between preferably etc.
Every) multiple apertures for being distributed.It can be envisaged that can be at the different height of medicament pipe vertical section
Be provided with it is multigroup along the circumferential direction equally spaced or unequal interval (preferably at equal intervals) distribution multiple holes
Mouthful.The agent outlet that can also be contemplated can be inclined hole, such as along the circumferencial direction of medicament pipe vertical section
Acclivitous multiple inclined holes of distribution, or drug direction are identical or opposite 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 for example can be gone out by flange with black water feeding pipe 1 and black water respectively
Expects pipe 2 is connected.The diameter of upper reducer gradually increases from black water feeding pipe 1 to vertical section, so that
The black water flowed into by black water feeding pipe 1 is contributed to further to be divided in upper reducer and vertical section
Dissipate, and the sufficient space of offer is sufficiently stirred for by impeller 4 in vertical section for black water.Lower reducer
Diameter be gradually reduced from vertical section to black water discharge nozzle 2 so that contribute to through impeller stir mix
Black water and the mixture of medicament converged in lower reducer, so as to contribute to black water and medicament
Further mixing.
(it is not shown) in another embodiment, agent outlet can be located at the upper change of casing 2
Footpath Duan Chu.Preferably there are the multiple agent outlets being along the circumferential direction distributed, more preferably with edge
Multiple agent outlets that circumferencial direction is equally spaced.In this embodiment, medicament pipe may not necessarily
Into the inside of casing 2, but medicament is set to be sent into from medicament source diameter in casing 2 by pressure, with
Black water from feeding pipe 1 converges, and is filled at the vertical section of casing 2 through the stirring realization of impeller 4
Divide mixing.
