Abstract
The utility model provides multi-product liquid-solid fluidized bed sorting and classifying equipment. A feed bin, a fluid distributor, density automatic controllers, a tapered tailings guide-flow channel and a plurality of sorting and classifying chambers are adopted, wherein the sorting and classifying chambers are sheathed together from bottom to top; a beneficiated ore guide-flow channel is arranged at the upper part of each sorting and classifying chamber; an added ascending water pipe with a plurality of nozzles is arranged in each beneficiated ore guide-flow channel; the outer wall of each sorting and classifying chamber and the underflow opening of the bottom sorting and classifying chamber are respectively provided with one density automatic controller; the fluid distributor is arranged at the bottom of the bottom sorting and classifying chamber; and a screwed feeder inserted into the bottom sorting and classifying chamber is arranged above the top sorting and classifying chamber. When materials are sorted and classified from bottom to top, the granules with the density being larger than that of a fluidized bed penetrate through the bed to the underflow and then are discharged as tailings or underflow at each segment; the granules with the density being smaller than that of the fluidized bed can not penetrate through the bed and are taken to overflow by ascending water flow, and then the granules are discharged as coal products at each segment, therefore, sorting and classifying for fluidization multi-products of materials are realized.
Description
Technical field
The utility model relates to multi-product liquid-solid fluid bed separation classification device, is particularly useful for the sorting classifying of coarse slime, also is applicable to the sorting classifying of quartz sand.
Background technology
Present most of coal preparation technique all adopts the gravity treatment and the flotation process combined of not desliming of not classification, both sorting granularity boundaries are 0.5mm, in fact the characteristics owing to two kinds of method for separating itself make that near the coal grain separating effect 0.5mm is relatively poor, and this part coal grain (refers generally to 3-0.25mm) GBs (GB/T 7186-1998) and is defined as coarse slime.And this part particle generally reclaims separately by the high frequency sieve in coal preparation plant, and its ash content is between cleaned coal and middle coal, and is generally high by 2-5% than cleans ash, and the final whereabouts of its product is difficult to determine.Generally not to its sorting, majority mixes cleaned coal with its part at present, and its prerequisite is that gravity treatment and floatation clean coal ash content must be lower than the final sales cleans ash, i.e. gravity treatment and flotation back of the body coarse slime ash content, and another part mixes middle coal.Fine particle content is big in China's part coal at present, adopt predictive desliming technology, contain a large amount of coarse slimes in the coal slime that removes, and this part coarse slime ash content height, all mix middle coal at present, have a strong impact on clean coal yield, have minority coal preparation plant to adopt heavily be situated between cyclone or spiral of minor diameter that coarse slime is carried out sorting in recent years, but because the deficiency of these two kinds of devices itself can't reach satisfied effect.And screening installation that this part coarse slime is badly in need of is simple in structure, easy to operate, sharpness of separation is high is with its branch two or more products of hanking.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, provides a kind of simple in structure, and floor space is little, and cost is low, the multi-product liquid-solid fluid bed separation classification device that sorting classifying is effective.
Multi-product liquid-solid fluid bed separation classification device of the present utility model, comprise feed hopper, fluid distributor, the density automatic controller, taper mine tailing guiding gutter also comprises a plurality of sorting classifyings chamber that is sleeved on together from bottom to top, and the top of each sorting classifying chamber is equipped with the concentrate guiding gutter, be equipped with a lifting pipe of adding that has a plurality of nozzles in each concentrate guiding gutter, be equipped with a density automatic controller in the underflow opening place of the outer wall of each sorting classifying chamber and sorting classifying chamber, bottom; Described fluid distributor is located at bottom, sorting classifying chamber, bottom; The top of top sorting grading room is provided with the screw(-type) feeder that inserts sorting classifying chamber, bottom.
Described a plurality of sorting classifyings chamber is 2～7; The described inlet of adding lifting pipe is equipped with control valve; Described density automatic controller is made of pressure sensor, by-pass valve control and PID or PLC auto-controller.
The beneficial effects of the utility model, utilize the density or the relevant characteristics of granularity of sinking speed and particle itself in the liquid-solid fluid bed layer that certain particle size density level scope endoparticle itself formed, realization is to the fecund product sorting classifying of material, improved the comprehensive utilization ratio of the productive rate and the coal resources of total cleaned coal, solved the present coarse slime of China with this and only reclaim the problem that coarse slime that not sorting is caused is sold the whereabouts embarrassment.By screw(-type) feeder, with the mass transport of high concentration sorting classifying chamber, bottom, make material segmentation from bottom to top in liquid-solid fluid bed separation classification device carry out sorting classifying to separator, improved separating effect greatly; Adopt the multitube fluid distributor, both guaranteed the uniformity of water inlet, reduced the clogging of inlet opening again, reduce accident rate, can accomplish the not blowing that stops; And employing PID density automatic controller, make the bed density sorting even, the sharpness of separation height, reduced the influence of pan feeding fluctuation to separating effect, every section product all can be realized regulating respectively simultaneously, can be in low-density less than realizing the high accuracy sorting under the 1.4Kg/L, significantly reduce cleans ash, improve the quality of products, be applicable to the sorting classifying of coarse slime, also be applicable to the sorting classifying of quartz sand.Its compact equipment, floor space is little, and cost is low, and sorting classifying is effective, installs easy to adjustly, and method of operating is simple, and a machine is a plurality of products of sorting classifying simultaneously, have practicality widely.
