The top of charging aperture, described discharge system is with described discharging opening in succession；
Described conical distributor is arranged on cylinder bottom, is double-decker, including outer conical shell and inner cone body, institute
Form breather chamber, described inner cone physically offers dividing of some distributing gas between the outer conical shell stated and inner cone body
Cloth hole, described outer conical shell lower end is connected with fluidisation air pipe, and the lower end of described inner cone body is connected with spouted air pipe,
Described spouted air pipe is arranged in described fluidisation air pipe, and co-axial；
Described agitating device includes the shaft running through cylinder end socket and the motor and the circle that are separately positioned on shaft two ends
Shape stirring wheel, described stirring wheel is arranged in cylinder, and described stirring wheel is located between described charging aperture and discharging opening；Described
It is additionally provided with spouted pipe, described spouted pipe upper end is located at immediately below described stirring wheel, lower end extends to inner cone body cone in cylinder
Shape intracavity, described spouted pipe is coaxial with cylinder.
Further, described discharge system includes being sequentially connected with material outlet pipe, material adapter, material expansion chamber,
Become net cage, peel off hired roughneck, pressure roller and convoying curtain；Described material outlet pipe is connected with described discharging opening, and described material connects
Pipe and material expansion chamber are arranged straight down, and described material adapter is connected by the elbow of inner wall smooth with material outlet pipe, institute
The material expansion chamber stated is in from top to bottom one-dimensional or two-dimensional expansion shape, and described material expansion chamber lower dimension becomes net cage with described
Entrance match, expansion chamber be in one-dimensional expansion when material expansion chamber section be in Long Circle, expansion chamber be in two-dimensional expansion when material
Expansion chamber ellipsoidal cross section；
Dust cage is installed in described one-tenth net cage, described dust cage is provided centrally with the air draught groove of opening upwards, described dust cage
It is additionally provided with the air draught outlet connecting with described air draught groove.
Preferably, the contour line of described material expansion chamber expansion is 3 °～15 ° with vertical curve angle γ, preferably 6 °～
10°.Material pneumatic speed in cylinder is higher, has jet characteristics.The angle of flare that effluxvelocity is distributed stable and uniform exists
Within 15 °.Angle too small is then as in Bottomhole pressure, and its underpart expansion is coordinated the expansion chamber of needs can be too with becoming net cage
Height, is unfavorable for equipment design and arrangement.
Further, it is provided with twin screw in described charging aperture.

With the distance of distributor bottom it is ensured that spouted fluidized cyclic space path and the jet subtended angle from spouted air pipe supplied materials air-flow
With jet entrainment space, the circulation unstability of this too short logistics of distance, oversize then spouted tube inlet section also can unstability, both
Useless power consumption can be produced.
Further, described fluidisation air pipe lower end is connected with inlet for fluidization air pipe, and described conical distributor lower end is extremely
Between inlet for fluidization air pipe, length is 8～20 times of described fluidized gas pipeline diameter, preferably 10～15 times.Ensure that fluidisation air-flow is steady
Fixed, too small then unstable, the excessive then waste device space.
The method carrying out the spouted fluidized dispersion mixing of multiple dimensioned solid phase using said apparatus, from spouted air pipe and material
The multiple dimensioned solid phase of charging aperture enters cylinder, and under stirring wheel effect, multiple dimensioned solid-phase material is in spouted pipe and its outer barrel
Gap interior circulation dispersion mixing between body, multiple dimensioned solid-phase material enters through the gap between stirring wheel and cylinder after being dispersed through and stirs
Mix in the barrel space of wheel top, exported by discharge system through discharging opening.
Preferably, the air velocity of described spouted pipe is 5～200m/s, preferably 30～120m/s, too low not defeated
Send and turbulence dispersion ability, too high can utter long and high-pitched sounds, produce vibration and even damage；In described fluidisation air pipe, gas flow rate is 0.5
～20m/s, preferably 2～8m/s, fluidized gas produce uniform velocity field in distributor bottom, suitable to the material that may sink to the bottom
Motive force, but avoid material to fall into pipeline again, it is configured according to the minimum sedimentation velocity of different scale and density solid phase.This
One speed is applied to most of diameter 1mm particles below.
The invention provides a kind of multiple dimensioned solid phase spouted fluidized dispersion mixing equipment is it is achieved that a kind of multiple dimensioned solid phase spray
Dynamic fluidization dispersions mixed method, can have to draw ratio the multiple dimensioned solid phase of magnitude differences to carry out efficient dispersion mixing, and become
