Description
Technical field
The invention belongs to ore dressing fields, are related to a kind of wet type ultrasonic vibrating screen.
Background technique
So-called sieve analysis is exactly that material is divided into several granularities by a series of different sieve of slot sizes by material
The process of rank, it is the important method that material size composition is analyzed in ore dressing field, in mineral working research and production field
There is critically important application.
Currently, material screening involved in ore dressing process has in the method that laboratory generallys use:
1. dry screen, when material is aqueous, less, the regular shape containing mud, while the requirement to analysis result is again not bery stringent, sieves grain
When degree relatively thick (generally higher than 0.074mm), dry screen can be directly carried out.Disadvantage: since what is generallyd use in ore dressing process is wet screening
Ore grinding, ore grinding product particle size is thin, and there are argillization phenomenon and product water content height, dry screen is difficult to directly be applicable in, more only works
For the subsequent less important work of screening operation；And the ultra-fine screening of small for some specific gravity mineral grain (such as coal slime particle carries out
0.01mm screening) and the ultra-fine screening of some mineral grains in irregular shape (such as sheet silicate mineral mica carries out
0.01mm screening), dry screen is equally difficult to efficiently separate.
2. wet screening, superfine material generated in grinding process is usually first had to carry out is exactly wet screening, i.e., will sieve
The suitable sieve of pore size is placed in clear water, and superfine material is poured on compass screen surface, is then made on compass screen surface by mechanical-physical vibration
Material generate vibration therewith, thus by be less than screen size material be sieved into water, the material greater than screen size stays in sieve
On face, it can just terminate until sieving lower clear water and being sieved when can not become muddiness again, be finally reached the purpose of sieve classification.Disadvantage: different
In dry screen, screening process can be completed by various moto-vibro screens.When carrying out wet screening operation in laboratory at present, generally all
It is to generate physics mechanical oscillation by the way of hand sieve, therefore there is a problem that screening efficiency is not high enough in screening process,
Especially for some superfine materials, (for granularity in the material of 0.037mm or less), the low problem of screening efficiency is especially prominent.Together
When, since fine mineral has great surface energy, the subparticle (general 0.037mm or less) or more of most mineral in water
Or it is few all in the presence of flocculation phenomenon, and granularity can significantly increase after particle flocculation, it will cause screening result to occur serious inclined
Difference.In addition, continuing to carry out wet screening in a manner of hand sieve to be also a greatly test for the skill and physical strength of operator, most
Whole screening effect is also not ideal enough.Therefore, the existing wet screening mode in laboratory is there is also certain deficiency, need to be made into
One step improves or optimization.
3. dry-wet mixed sieve of joint, i.e., combine dry screen and wet screening, ore grinding product first carries out wet screening, then will be on sieve
Dry screen operation is carried out after drying materials.Its operating main body and key are still wet screening operations, and dry screen operation only plays one
Subsequent booster action.
Summary of the invention
The present invention provides a kind of equipment that can significantly improve screening efficiency, and ultrasound, reciprocating motion is good with wet screening process
Be combined together, be different from the general physical vibration generated by hand sieve, material wet screening process is superimposed ultrasound on compass screen surface

It is standby to unload completely, it is finally taken out from base 1 and hangs basin 2, hung in basin 2 and obtain undersize material.
For sieving calcite, since calcite particle is when less than 40 μm, calcite aqueous solution is in alkalinity,
Intergranular electrostatic repulsion weakens, and specific surface energy is very big, and particle is obvious by Van der Waals force and hydrophobic attraction function influence, easily wads a quilt with cotton
Group, floc sedimentation are not only easy fine particle groups is made to be polymerized to coarse granule to cause fine grained in final products that can not be completely removed, can also lead
It causes to interfere with each other between floc sedimentation and particle in infall process, influences final settlement as a result, causing product granularity inaccurate.Comparison is normal
It advises elutriation screening and is sieved using the wet type ultrasonic vibrating screen of the present embodiment, use Malvern laser particle size analyzer (model
MASTERSIZER 2000) grain size analysis is carried out, Figure 11 is the calcite particle for being 10-40 μm by elutriation method Sieving and casing
Grain size analysis, carried secretly it can be found that there is apparent fine grained by the product that elutriation method obtains, Figure 12 is using real
The grain size analysis for the calcite particle that the wet type ultrasonic vibrating screen Sieving and casing for applying example 1 is 10-40 μm, it can be found that obtained production
There is not fine grained entrainment in product；Figure 13 is the grain size analysis for the calcite particle for being -10 μm by elutriation method Sieving and casing,
Figure 14 is to use the wet type ultrasonic vibrating screen Sieving and casing of embodiment 1 for the grain size analysis of -10 μm of calcite particle, comparison diagram
When 13 and Figure 14 be can be seen that using elutriation method, calcite particle is most preferably being settled in infall process due to being difficult to control
Concentration causes to interfere between particle, affects the upper limit of elutriation, causes -10 μm of calcite overall particle sizes partially thick, and uses real
The wet type ultrasonic vibrating screen screening for applying example 1 is then not in the problem, therefore ultrasound vibration sieves obtained clay ratio silt also compared with water
It is more accurate to analyse curve.
In order to improve screening efficiency, can be set multiple rigid supports 5, each rigid support with above-mentioned rigid support 5
Connection type it is identical, multiple rigid supports 5, which are disposed side by side on, to be hung inside basin 2, and more than one connection converter 4 is connected in parallel on
On, and connect by being coupled converter 4 with the output end of reciprocating motor 3, reciprocating motor 3, which drives to be coupled while reciprocating motion, to be turned
Parallel operation and rigid support 5 are back and forth run, and can thus be placed multiple sieves while be sieved, and screening effect is significant, screening
Efficiency improves.
