Abstract
The utility model discloses a multi-cylinder upwelling hydraulic classifier. The multi-cylinder upwelling hydraulic classifier consists of two or more than two classifying cylinder bodies; the classifying cylinder of the larger diameter (2) is arranged and covered outside the classifying cylinder of the smaller diameter (1); the outside of the classifying cylinder of the larger diameter (2) is provided with a overflow weir (3) with an oblique bottom; the top of the classifying cylinder of the smaller diameter (1) is provided with a slurry distributor (11); the bottoms of the classifying cylinder of the smaller diameter (1) and the classifying cylinder of the larger diameter (2) are provided with a water feeding device and a material discharging device; the height of the upper edge of the classifying cylinder of the smaller diameter (1) is higher than the classifying cylinder of the larger diameter (2). One piece of equipment realizes the twice or more than twice classification of the granularity; the bulk materials will be divided into three or more than three granule levels at the same time according to the size of the granularity. The upwelling water is filled by the water sprinkling plate (8); therefore, the upwelling water is evenly distributed on the cross-section of the classifying cylinder bodies, which is conducive to the improvement of the classification effects.
Description
Technical field
The utility model relates to the hydraulic classification equipment that a kind of ore dressing is used, and is to carry out grading, can obtain the invention of upwelling hydraulic classifiers product, many more than three kinds simultaneously about the bulk material to size fractionated.
Background technology
Often material need be divided into several other products of different grain size level in ore dressing and field of powder engineering, for thinner material, the mechanical grading method is often powerless, and therefore, hydraulic classiciation becomes indispensable equipment.Hydraulic classifier is the difference of the sinking speed in water according to different densities or varigrained material, makes material obtain separating by the speed that changes ascending current.
The existing equipment that is called as hydraulic classiciation has multiple, for example, and spiral hydraulic classifier, hydrocyclone and upwelling hydraulic classifier etc.The invention belongs to the upwelling hydraulic classifier, the feedwater of this grader is to be gushed out by equally distributed aperture on the porous stabilier of bottom, and current distribute comparatively even, and grading effect is better.But existing upwelling hydraulic classifier all is a monotubular, can only obtain overflow (particulate) and two kinds of products of sand setting (coarse grain).Obtain the material of grade more than three kinds or three kinds if desired simultaneously, then need with the equipment more than two, this will increase equipment difficulty in the configuration, also will increase factory building height and operation link, make the increase of investment and cost.
Chinese patent CN2299664Y discloses a kind of micron power hydraulic classifier, is made up of four cylinders side by side, but only is applicable to the micro mist that 100 μ M are following, and the arrangement of cylindrical shell adopts word group to open, floor space is bigger, and equipment uses material more, and weight is bigger.
Summary of the invention
In order to overcome the prior art above shortcomings, the utility model provides a kind of many upwelling hydraulic classifier, and this many upwelling hydraulic classifier promptly has higher classification efficiency can obtain two or more products simultaneously again.
The technical scheme that its technical problem that solves the utility model adopts is: be made up of the multi-layer cylinder that diameter is different, the big jacket casing of diameter is in the little tube outside of diameter, and dispenser is arranged at the top of minor diameter tube, in the bottom of tube waterworks and discharge device is arranged.During work, the raw material of being made up of sand and water at first feeds in the pulp distributer, is fed equably in the assorting cylinder by pulp distributer again, and solid particle moves downward under the effect of gravity.Waterworks in the bottom of tube are made up of water spray plate (or claiming stabilier), water tank, a feed pipe that is covered with aperture.Outside feedwater with certain pressure tangentially feeds water tank between porous plate and the base plate by water pipe; again by upwards ejection of the aperture on the stabilier; this ascending water forms the fluidization bed with specific density and viscosity gradually with the solid particle that moves downward; can pass this bed greater than the particle of a certain granularity sinks to the bottom and discharges from drainage conduit and valve; become product 1;, the particle of a certain granularity overflows and enters the assorting cylinder of outside less than can not passing this bed along circumference with ascending current; obtain classification again therein; the diameter of the assorting cylinder of outside is greater than central cylinder; be enclosed within the outside of central tube; the stabilier that the also useful stephanoporate steel plate in the bottom of cylindrical shell is made; water can be from ejection here; sink to the bottom than coarse granule, discharge, obtain product 2 through drainage conduit and valve; fine grained is with discharging from the top in the overflow; enter in the downflow weir of band wedged bottom, and from discharge gate, discharge, become product 3.
The utility model makes up by rational structure, and the overflow that makes classification for the first time in central cylinder can obtain varigrained three kinds of products simultaneously just in time as the feed of secondary classification.With regard to granularmetric composition, the particle diameter of the particle diameter＞product 3 of the particle diameter＞product 2 of product 1.
When needs are divided into 4 kinds or more kinds of product, can increase one or several cylindrical shells again in the outside of major diameter assorting cylinder.
The diameter of each layer classification cylindrical shell needs to determine according to combined factors such as partition size, output, confluent, concentration.Concrete computational methods can be referring to the related content of two-phase fluid theory of mechanics.
The assorting cylinder cylindrical shell of outside is because the bigger need of diameter are established 4 or more discharge gates.
On water spray plate, the rubber mouth can be installed, can improve the life-span of porous plate.
The beneficial effects of the utility model are: feedwater is to feed by the porous plate that evenly is covered with aperture, under the situation of pressure that feeds water and stability of flow, and the current distribution uniform.When guaranteeing the higher classification efficiency that the upwelling hydraulic classifier has, can obtain three kinds of graded products simultaneously, when needs are divided into 4 kinds or more kinds of product, can increase one or several cylindrical shells again in the outside of assorting cylinder.Compact equipment is saved material, easy for installation.
