Description
Technical field
The invention belongs to mineral floating machinery equipment technical fields, particularly relate to a kind of flotation pulp pretreatment dress
It sets.
Background technology
Flotation is one of main method of sorting mineral, and the process of sizing mixing is to realize the premise of mineral efficient flotation separation.It passes
The ore pulp set-up procedure of system is, to realize that mineral grain is fully dispersed, to be convenient for mine by carrying out stirring of sizing mixing in mixing barrel
Slurry conveying；It realizes agent molecule dispersion and is adsorbed in mineral particle surface；The effects that adjusting floatation concentration.It can by the effect of sizing mixing
To be adsorbed in solid particles surface by different suction-operated collecting agents and inhibitor, remaining regulator and foaming agent are fully and mine
Slurries body mixes.However, most of floating agent is larger molecular organics, solubility and dispersibility are poor.In production practices, letter
Single stirring of sizing mixing often results in agent molecule and cannot adequately be adsorbed in mineral particle surface, and caused by medicament it is largely unrestrained
Take, unavoidable ion is made to increase, flotation solution chemistry deteriorates, and flotation efficiency is made to reduce.Therefore, the fine or not of dosing of sizing mixing divides flotation
From playing a crucial role, efficient ore pulp pretreatment unit is to improve FLOTATION SEPARATION effect, and reducing reagent consumption most has
One of means of effect.
Invention content
The purpose of the present invention exactly for the above-mentioned prior art present in because size mixing stir it is insufficient, caused by flotation
One is provided in place of the deficiencies of reagent consumption is big, flotation efficiency is low, sorting process is complicated, cost is higher, environmental protection pressure is big
Kind strengthens a kind of efficient flotation separation ore pulp pretreatment unit of suction-operated based on step.The present invention passes through jet stream, mixed on low speed, " W
The step of type stream " strengthens suction-operated, improves agent molecule and mineral grain adsorption effect, improves flotation efficiency, equipment volume
It is small, it is simple in structure, convenient for safeguarding.
The purpose of the present invention can be achieved through the following technical solutions：
The flotation pulp pretreatment unit of the present invention includes ore pulp bucket that bottom is provided with ore pulp underflow opening, from the bottom to top with mine

The stirring chemical feed pipe for adding medicament into stirring shaft sleeve outside to ore pulp bucket, ore pulp is provided in the upper lateral part of ore pulp bucket
Overflow launder and ore pulp discharge port, around ore pulp bucket outer wall be equipped with ore pulp material inlet, emulsification dosing mouth and several
The ring pipe of isocon, the nozzle being connected with isocon outlet is respectively tangentially to stretch into ore pulp bucket.
Heretofore described stirring shaft sleeve is suspended in below the upper cover body of ore pulp bucket, and is uniformly divided on stirring shaft sleeve
Several circular through holes of cloth；The stirring blade by be installed in stirring shaft sleeve and the agitating shaft that extends straight up with
The motor driven systems at the top of ore pulp bucket are arranged to be combined, and in a suspended manner below setting stirring shaft sleeve.
The square structure in cross section of heretofore described ring pipe is arranged around the ring pipe in a manner of uniformly distributed
There are six isocons；The ore pulp bottom of the barrel is 45 degree of centrums, and is equipped with maintenance underflow control valve, and staving passes through connector
It is fixedly mounted in rack.
The tangential approach axis of nozzle being connected with isocon outlet in the present invention with stirring blade rotation direction on the contrary,
The high-speed jet that nozzle generates, stirring blade generate negative pressure sucking effect with sleeve, and opposite direction makes two fluids form " W
Type stream " increases the secondary mixing of ore pulp.
Heretofore described feeding mouth, ring pipe are fixed in horizontal direction below pretreatment unit ore pulp bucket at 600mm,
Ring pipe to ensure that the nozzle of isocon can tangentially pass in and out staving, and can realize maintenance and replacement apart from staving 50mm.
The working principle and beneficial effect of the present invention is as follows：
Raw ore slurry enters ring pipe, first kind floating agent by ore pulp material inlet（Such as regulator, collecting agent or indissoluble
Property, difficult dispersions etc.）Also entered in ring pipe by emulsifying dosing mouth, first kind medicament carries out just with ore pulp in ring pipe
Step mixing.Preliminary mixed ore pulp is tangentially entered in ore pulp bucket, herein mistake from the nozzle of 6 isocons with high-speed jet
Cheng Zhong, first kind medicament is dispersed into emulsified state, and agent molecule is adsorbed in mineral surfaces under high action of turbulent flow（Pass through medicament
High-speed jet effect with ore pulp is realized slightly solubility reagent emulsifying and is efficiently adhered in mineral particle surface）.At the same time pass through
Stirring chemical feed pipe adds the second class medicament into stirring shaft sleeve（Such as foaming agent, soluble dispersions etc.）, motor driving
System drive agitating shaft realizes the second class medicament and ore pulp mixing and absorption with 300r/min rotating speeds, and ore pulp is made to be in suspended state,
Fully after dissociation, granularity and concentration meet the raw ore slurry of flotation requirement.Pretreated ore pulp is discharged by overflow launder from ore pulp
Mouth outflow.The ore pulp underflow opening of ore pulp bottom of the barrel setting, in case discharge, maintenance down.
In above-mentioned efficient flotation separation ore pulp pretreatment unit, the ore pulp of absorption and particle surface after high-speed jet emulsifies
By stirring shaft sleeve, motor driving stirring blade realizes the suspension of ore pulp, and forms " W " type stream in staving, soluble point
The second scattered class medicament is added in stirring shaft sleeve by stirring chemical feed pipe at 75cm height, and second is realized under low action of turbulent flow
Mixing, absorption and the suspension of class medicament.
In conclusion the invention has the advantages that：Reagent consumption amount is reduced, improves agent molecule and is imitated with mineral grain absorption
Fruit reduces unavoidable ion in flotation；Equipment volume is small, simple in structure, convenient for safeguarding.
