Description
Technical field
The utility model belongs to mining equiment flotation technology field more particularly to a kind of pipeline static mixing mineralization device.
Background technique
In sorting mineral, the flotation recovery of fine-particle minerals is always the problem of mineral manufacture field.As mineral products provide
The poor thin hydridization in source, fine-graded ore proportion is continuously improved, in addition, ore grinding link produces while levigate ore
A large amount of secondary fine, which results in microfine ores in floatation process to occupy certain ratio.However fine-particle minerals due to
Volume is small, small with the collision probability of floating agent during sizing mixing so that floating agent can not well with mineral grain
Effect, causes the fine-particle minerals containing valuable metal that can not adhere to bubble in floatation process and largely lose in tailing,
Cause being largely lost for resource.
The apparent partial size for increasing particle is one of the main path realizing fine-particle minerals and effectively sorting.Increase the table of particle
Partial size is seen, realizes that the conventional flotation of fine-particle minerals, main path are to make fine-particle minerals under the premise of ore pulp is fully dispersed
Selective hydrophobization forms agglomerate, is then separated again with proper method, and relevant technique is referred to as " hydrophobic flocculation sorting
Method ", such as Shear flocculation flotation.Shear flocculation theory basic thought is that surfactant is added in fine suspension system (to catch
Receive agent), sufficiently large shearing force is then generated by high-speed stirred, makes the fine-particle minerals hydration shell for being adsorbed with surfactant
Rupture and assemble it is agglomerating, to increase its apparent diameter, then with froth flotation method by wadding body emersion.To form sufficiently large shearing
Power, agitating paddle needs very high revolving speed to traditional blender at runtime, however high revolving speed needs very high energy consumption, simultaneously
It is also very serious to the abrasion of equipment.And static mixer is to be fixed on static mixing element in pipeline with certain arrangement mode
It is formed by pipeline mixer.Its inside does not have moving component, mainly realizes with fluid flowing and internal element various

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1 and Fig. 2, a kind of pipeline static mixing mineralization device, including tube body 1, spray gun 2, mixed cell 3, screw thread
Constrictor 4, flange 5,1 one end of tube body are connected with flange 5, and the other end of tube body 1 is connected with spray gun 2, and the other end of spray gun 2 also connects
Be connected to flange, the specific structure of mixed cell 3 is identical as the structure in patent 201220559884.0, including it is parallel it is two rows of with
Upper and criss-cross batten 31, several mixed cells 3 are arranged in tube body 1, and the batten 31 of each mixed cell 3 is along tube body
Axial successively tilting and parallel interval setting.As for the particular number of mixed cell, those skilled in the art can be according to reality
Mixing needs to be adjusted.Screw thread constrictor 4 is additionally provided between adjacent two mixed cell in tube body 1, screw thread constrictor 4 is in
Hollow tube shape, including towards the sequentially connected contraction section 41 of tube body export direction, flat segments 42 and diffuser 43, flat segments 42
Inner wall be equipped with axially extending screw thread.
The working principle of the utility model is as follows: after ore pulp is mixed with floating agent, it is mixed to enter pipeline static through pressure pump
The spray gun 2 of mineralization device is closed, ore pulp is injected into tube body 1 through 2 high speed of spray gun, and ore pulp passes through 3 He of mixed cell being arranged alternately
Screw thread constrictor 4 occurs the movements such as shearing, shunting, interflow, rotation and deflecting, is finally discharged from 1 one end of tube body.Pipeline static
Mixing liquid-liquid dispersions process in mineralization device includes the two kinds of behaviors of dispersion mixing and distributed rendering, and wherein dispersion mixing is that drop is broken
The process gathered with drop and finally realize dynamic equilibrium is split, distributed rendering is that two phase concentrations spatially finally realize uniform point
The process of cloth.Two processes continue to develop on the length direction all along pipeline static mixing mineralization device.Ore pulp is received in screw thread
The contraction section 41 of contracting device 4 is since the diminution of tube body cross section causes pressure gradually to convert to kinetic energy, and flow velocity is accelerated, by straight
Ore pulp can be rotated along screw thread when section 42, so that ore pulp is sufficiently mixed, the ore pulp outflow thread segment of rotation enters diffuser
43, due to the unexpected increase of 43 cross section of diffuser, cause the kinetic energy of ore pulp to gradate for pressure energy, hence into next
Mixed cell.Mixed cell 3 and screw thread constrictor 4 are intervally arranged, so that ore pulp and floating agent can access good point
It dissipates, to realize that ore pulp is mixed with the full and uniform of floating agent.
Referring to Fig. 1 and Fig. 2, to further increase mixing efficiency, the thread rotary orientation of two neighboring screw thread constrictor 4 on the contrary,
The axis of spray gun 2 is overlapped with the axis of tube body 1, and the length ratio of contraction section 41, flat segments 42 and diffuser 43 is 1:2:1, is received
The longitudinal section of contracting section 41 and diffuser 43 is taper, and cone angle is 90~100 °, the ratio of flat segments 42 Major Diam and path
For 2:1.
Referring to Fig. 3, a kind of application method of pipeline static mixing mineralization device, ore pulp 6 and floating agent 7 are in agitator 8
In mixed, it is pressurized pump 9 enter pipeline static mixing mineralization devices, then ore pulp after sufficiently acting on from pipeline static mix
The discharge of mineralization device one end is closed, the pipeline static mixing mineralization device being concatenated is mixed again, is finally discharged mixed
Ore pulp.
