Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described。
Such as accompanying drawing 1 and the spiral enrichment facility shown in accompanying drawing 2, including snail shape pipeline 5, the one end of described snail shape pipeline 5 is provided with charging aperture 1, the other end is provided with dividing plate 6 and is divided into inside and outside two discharging openings, wherein it is provided with concentrate discharging opening 2 relative to the discharge outlet of the outer side, center of snail shape pipeline 5, leans on the discharge outlet of inner side to be provided with recirculated water discharge gate 3 relative to the center of snail shape pipeline 5。The cross section of described snail shape pipeline 5 is square, and for two circle pipelines of arbitrary neighborhood in snail shape pipeline 5, the outside of an interior circle pipeline is bonded to each other with the inner side of an outer circle pipeline。
The operation principle of this structure adopted is: black water circles at snail shape pipeline 5, due to solid relatively liquid weight, so the centrifugal force being subject in snail shape pipeline is also bigger, thus, when black water flow velocity in snail shape pipeline is enough, solid-liquid separation can be realized, go out to separate in the outlet of snail shape pipeline by coal slime and the recirculated water after concentration and export respectively。And squarely is done in the cross section of snail shape pipeline 5, two circle pipelines adjacent inside and outside it can be made form bonded to each other, so can so that the structure of whole enrichment facility becomes compact, and square-section is bigger compared to the circular cross-section pipeline not only area of section accounting for equal space, and the processing cost of square-section is more much lower than the processing cost of circular cross-section, it is possible to greatly save cost。This structure also more saves space and easy to process than the pipeline of the helix tube type structure of spring-like。
In the second embodiment, described snail shape pipeline 5 has flexibility, and it is fixed relative to ground near one end of spiral center, and under duty, snail shape pipeline 5 can carry out diastole by its spiral center relatively。So when the force value of the black water in pipeline is too high, snail shape pipeline 5 can pass through the diastole campaign of self and carry out alleviating pressure, it is prevented that pipeline damage, improves the life-span of pipeline。
One as the second embodiment realizes structure, as shown in Figure 3, described snail shape pipeline 5 is made up of inner part 51 and Outboard Sections 52 relative to its spiral center, described inner part 51 is all the both sides strips with the snail shape of zigzag flange with Outboard Sections 52, and the zigzag flange of inner part 51 and the zigzag flange of Outboard Sections 52 are mutually twisted and are stitched together；Described inner part 51 is made up of the plastic material with flexibility, it is possible to be rubber；Described Outboard Sections 52 is made by having elastic metal material, it is possible to be spring steel。Adopt this structure; once system jam; in pipeline, hydraulic pressure is too high; Outboard Sections 52 will be opened in diastole so that the spiral entirety of snail shape pipeline 5 becomes big, even can become straight pipeline under extreme condition; pipeline is had good protective effect; and Outboard Sections 52 adopts metal material to be possible to prevent abrasion, inner part 51 can be capable of expansion and contraction, adapts to the diastole of Outboard Sections 52。
Concentration owing to inputting the black water of spiral enrichment facility every time is different, therefore the concentrate exported is also different from the ratio of recirculated water, therefore on dividing plate 6, it is connected to adjustment valve 4, described adjustment valve 4 can drive dividing plate 6 to rotate relative to described snail shape pipeline 5, to change the ratio of inside and outside two discharging openings, so can improve the adaptability of device so that it is be adapted to the black water of variable concentrations。
