Description

A kind of wet type grain size analysis vibration bushing screen and application thereof
Technical field
The invention belongs to ore dressing field, relate to sieve test equipment and the application thereof of material being carried out to classification, particularly a kind of wet type grain size analysis vibration bushing screen and application thereof.
Background technology
Sieve analysis carries out classification to solid material, measures raw meal particle size composition, and can by analysis, the character of research size fractionated, mineralogical composition at the effective ways of size fractionated distributive law etc., in mineral working research and extensive use in producing.
The method being usually used in grain size analysis is at present:
1. manually sieve, general applicable graininess wider range, determines sieve classification granularity as required, sieves on sieve and sieves lower two ranks, if be divided into multiple rank, repeatedly need complete with the sieve of different sieve aperture with sieve.Shortcoming: inconvenient operation, Measuring Time is long.
2. dry type vibratory bushing screen, is generally used for check screening, assisting as other Analytical Methods of Grain Grade.Shortcoming: screening effect is poor, poorer to fine material effect, even cannot complete classification, dust is large, and screen cloth loss is large.
3. hydraulic analysis, being the method for the free-falling velocity indirect measurement raw meal particle size composition by measuring particle, being applicable to the fine material that granularity is less than 1mm.Shortcoming: classification cannot be carried out to coarse-grained material, grading time is long, because sinking speed is relevant with material density, grain shape and medium viscosity etc., and most of grading raw material in beneficiation research, size fractionated density is variant, complex-shaped, medium viscosity also changes with changes such as temperature, and classification error is large.
Summary of the invention
The invention provides a kind of wet type grain size analysis vibration bushing screen and application thereof, sieve analysis can be carried out to material efficiently and accurately.
The structure of a kind of wet type grain size analysis vibration bushing screen provided by the invention comprises:

Electromagnetic vibrator (1) and vibrating disk (2) and the standard bushing screen hanger (5) be connected with vibrating disk form vertical vibration device, rubber spring (3), vibrating disk pillar (7) and base (8) support and fix whole vibrating device, standard bushing screen (11) is made up of the standard screen of 1-5 different pore size, be placed on standard bushing screen hanger chassis (6), compress with platen (4) on standard bushing screen above and fixed by platen geometrical clamp (9) on standard bushing screen.Standard bushing screen is immersed in tank (10), and discharge outlet (12) is in tank (10) bottom.Most fine fraction is stayed in tank, is discharged after screening terminates by discharge outlet (12).
On described standard bushing screen, platen (4) arranges screen cloth, and sieve aperture is less than or equal to orlop standard screen, or the standard screen of a most fine pore is placed on the standard bushing screen the superiors, enters in tank to prevent coarse fraction.
Between two described standard screens, outside latex circle or annular tie up modular belt cover tightening seal, prevent material from dishing out between two standard screens.
A kind of using method of wet type grain size analysis vibration bushing screen is as follows:
A. upwards mention vibrating disk to take off from vibrating disk pillar together with standard bushing screen hanger;
B. required bushing screen is selected by classification requirement, the most fine-graded sieve needs two, and one is placed on lowermost layer, and another is placed on the superiors, wetting material to be fractionated is put in the sieve of the thickest rank of the second layer, packages standard screen and the interface between sieve overlapped tight with latex circle;
C. the standard screen packaged is put in standard bushing screen hanger, is fixedly clamped with platen geometrical clamp on standard bushing screen after compressing with platen;
4 of vibrating disk trepannings are aimed at vibrating disk pillar and are inserted in, making vibrating disk steadily be positioned on the rubber spring of vibrating disk pillar by the standard bushing screen of d. mentioning vibrating disk and combining;
E. use plug jam-pack water-trough outlet and to tank water filling, water surface Mei Guo the superiors screen cloth stops water filling, to reduce water consumption as far as possible;
F. Vibration on Start-up device, stops after 5-30 minute, pulls up discharge outlet plug, by water emptying, and fully rinse tank, the thinnest rank undersize material is discharged;
G. e, f step is repeated, until do not have fine or little fine in water channel drain;
H., after taking off vibrating disk and standard bushing screen, unclamp platen geometrical clamp on standard bushing screen, take off standard screen, the on-the-sieve material wash bottle of size fractionated be flushed in little basin, filter respectively, dry, weigh, sampling, analytical test is carried out, off-test.
The present invention is compared with existing similar technique, and its significant beneficial effect is embodied in:
The scope of application of the present invention is wide, easy to operate, effectiveness of classification is high, stable operation, measure error are little, Measuring Time is short, operating environment dust is little, can in scientific research and extensive use in producing.
