Abstract
The utility model relates to a novel coal-selecting device; a composite, filling and segmentation type air-distributing device is designed in the coal-selecting device, and the many stages small-size air-distributing devices are jogged to a large size air-distributing device; the purpose of sorting the coal is achieved by using the fluidized bed technique in the coal-selecting process. The utility model solves the problems that the water consumption is big, and the slurry water processing is difficult in the current wet coal-selecting; the utility model has the advantages of less investment and obvious effect; new pathway is opened for the coal sorting in the water-deficient area.
Description
The utility model discloses a kind of dry fluidized bed sorting unit of novel coal separation process that fluidization is applied to.
Existing coal separation is to adopt wet split, and this method not only can cause the pollution of residue coal slime after the washing, and water consumption is big, investment is high.Provinces such as the Shaanxi that is distributed in the severe drought lack of water more than 2/3rds of coal in China recoverable reserves, Inner Mongol, Shanxi.Therefore wet split has also influenced the raising of these regional Coal Quality.
Task of the present utility model provides a kind of novel sorting unit, and it not only can solve the deficiency that wet split exists, and can reach the precision of wet split simply, effectively.
Task of the present utility model is finished in the following manner: after passing the gas flow modulation measuring system as the air stream of fluidizing agent, enter the air-distribution device of fluid bed housing lower end through appendix, so that air velocity enters in the upper fluid-bed after evenly again, and pass fluidisation magnetite powder and quartz sand and mix the dense media layer of forming and flow out.After air velocity reached minimum fluidizing velocity, the different-grain diameter raw coal that is added by the cycle charging gear on fluid bed housing top will be suspended in the differing heights of bed by the density size under the supporting of dense media, thereby reaches the purpose of sorting.Coal and dense media can be sent into by the cycle charging gear on top.Cleaned coal after the sorting and spoil are exported after removing medium apparatus by an anchor chain scraper plate output system that is contained in the fluid bed.
In device, fluid bed housing one-tenth "
" the type shape, so that coal and spoil after the output sorting.
In addition, in air-distribution device, air stream at first is that the pre-air compartment that enters the bottom slows down, all presses, and passes top pre-air distribution plate with low speed, steady air flow.Pre-air compartment is that a top is cuboid, and the bottom is the casing that chamfered edge platform shape combines; Pre-air distribution plate then adopts the straight hole plate and directly is fastened on the angle steel that is welded on the housing of pre-wind cloth chamber.Better for making as the air velocity uniformity of fluidizing agent, install the incompressible packed layer that one deck is made up of glass marble additional on pre-air distribution plate top, and in incompressible packed layer, increase by one group "
" type cuts apart plate, and incompressible packed layer is separated into a plurality of square shapes; Simultaneously, for preventing that coal grain and dense media fall into the incompressible packed layer of bottom and the uniformity that further increases fluidizing agent in the fluidized-bed layer, be provided with the tissue layer of holding by the two layer screen network folder on incompressible stratum top, two-layer screen cloth is positioned at air-distribution device and fluid bed housing junction, can make the tight tissue layer of two layer screen network folder by fastening both sides bolt.
Choose at branch, because the fluid bed size is too big, only adopt single large scale air-distribution device, its fluid effect is relatively poor.Therefore, fluid bed coal separation device adopts a plurality of air-distribution device combination methods, by being the air-distribution device of the large scale bed of a Len req through vertically being put together with several same small size air-distribution devices.
Describe below in conjunction with accompanying drawing:
Fig. 1 is that the structure master of dressing coal with dry fluidized bed device looks schematic diagram.
Fig. 2 is that the structure master of air-distribution device in the dressing coal with dry fluidized bed device (6) looks, cross-sectional schematic.
Fig. 3 is the A-A face cutaway top view of Fig. 2.
Among Fig. 1, cross gas flow modulation measuring system 7 as the air communication of fluidizing agent after, in appendix 9 enters the air-distribution device 6 of fluid bed housing 3 lower ends, be decelerated homogenizing.Thereafter, air flows to into contacting with raw coal in the fluid bed housing 3 on top and with wherein dense media, raw coal is to enter by the cycle charging gear 8 that is arranged on fluid bed housing 3 upper ends, and cleaned coal after the sorting and spoil by fluid bed housing 3 inside anchor chain one scraper plate output system 1 and anchor chain one scraper plate be system 1 upper end remove medium apparatus 2 outputs.
By Fig. 2 and Fig. 3 as can be known, appendix 9 and top cuboid, bottom are that the pre-air compartment 10 of chamfered edge platform shape links, and the pre-air distribution plate 5 on pre-air compartment 10 tops is to adopt the straight hole plate, and by bolted on the angle steel that is welded on pre-air compartment 10 walls.By diameter is that the certain thickness incompressible packed layer 12 that the glass marble of 4-10mm is formed is a supporter with pre-air distribution plate 5; Simultaneously, in incompressible packed layer 12, increase the plate of cutting apart of one group of " Nian " type again; make incompressible packed layer 12 be divided into the equal-volume tetragonal body; on incompressible packed layer 12; fluid bed housing 3 and pre-air-distribution device 6 junctions are provided with the rectangle tissue layer 13 by two-layer screen cloth 4 clampings.
In addition, air-distribution device 6 is put together by many among Fig. 1.Small size air-distribution device with 150 * 150mm is formed the long large scale air-distribution device of a 900mm through vertical amalgamation.
By between density level the difference 0.05g/cm
3The experiment of density ball in dry fluidized bed sorting unit, its sorting possible deviation value E
P=0.025, this numerical value is well below the jigging sorting of routine, approaches the existing wet method separating effect that heavily is situated between.
The utility model coal-selecting device in dry fluidized, except having dry advantage, it is low also to have a cost, small investment, the advantage such as environmental pollution is few. Compare with the wet coal preparation factory of similar scale, investment cost reduces 2/3, and producing cost also reduces 2/3. The utility model is that new way has been opened up in water-deficient area and the sorting of meeting the coal of the easy argillization of water.
