Description
The present invention relates to coal washing and screening plant in a kind of adjustable self-rotary, it belongs to a kind of cyclonic unit of separating solid substances.
Present existing cyclone is because its design is unreasonable, make there is can not dynamic adjustments washing parameter, big, the wear equipment of the scouring force of equipment soon and shortcoming such as inferior separating effect.Centering coal particularly, this equipment especially can't washings.
The purpose of this invention is to provide a kind of have can dynamically regulate, reduce equipment attrition and the washing good separating effect, can washing in coal washing and screening plant in the adjustable self-rotary of coal.
Task of the present invention adopts following technical proposal to finish: in this adjustable self-rotary the coal washing and screening plant it comprise two adjustable self-rotary cyclones, consumer unit, program control case, supply-water pump and slag extractors, described adjustable self-rotary cyclone comprises cone tube, circle tube, water inlet, lid, dividing plate, impeller, helical wheel, turning cylinder, speed changer, motor, several dynamic sample taps, adjustable overflow cylinder, crushing feeder, gives barrel, coarse fodder outlet, fine fodder outlet and some gussets; The circle wound packages is on the top of cone tube, lid is contained in the upper end of circle tube, dividing plate is located at the centre of circle tube, impeller and helical wheel are located at the bottom of turning cylinder and at a distance of certain distance, the upper end and the speed changer of turning cylinder link, motor is contained on the speed changer, speed changer is contained in the central authorities of lid, the lower end of turning cylinder is contained in the bottom of cone tube, several dynamic sample taps are located at the middle part and the top of cone tube, adjustable overflow cylinder is located at the central authorities of dividing plate and turning cylinder is passed from its central authorities, crushing feeder is located at the top to barrel, be contained on the tangential direction of circle tube the lower partition for the bottom of barrel, water inlet is located at the bottom to barrel, the fine fodder outlet is located on the tangential direction on circle tube dividing plate top, and some gussets are contained in the bottom of cone tube and become 30 ° of angles with the conrotatory flow path direction of cone, and the coarse fodder outlet is located at the lower end of cone tube; Two adjustable self-rotary cyclones are cascaded, and slag extractor is located in the coarse fodder outlet of adjustable self-rotary cyclone, and supply-water pump is connected with the water inlet of the adjustable self-rotary cyclone of the first order.
Because the present invention has adopted technique scheme, therefore compare with background technology, have following advantage:
1, has the dynamic adjustments function,, therefore make cyclone under different rotating speeds, produce different flow velocitys,, realize dynamic adjustments to adapt to different coal washings owing in cyclone, increased the rotating shaft of a rotation rate-controllable;
2, equipment attrition is little, good separating effect;
3, coal and grading effect are good in the energy washing;
4, set up three dynamic sample taps, can extract dynamic parameter at any time.
The present invention is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of adjustable self-rotary cyclone;
Fig. 2 is the structural representation of coal washing and screening plant in the adjustable self-rotary.
As depicted in figs. 1 and 2, the coal washing and screening plant comprises two adjustable self-rotary cyclones 21 and 22, consumer unit 24, program control case 18, supply-water pump 19 and slag extractor 20 in the adjustable self-rotary of the present invention, and described adjustable self-rotary cyclone comprises cone tube 11, circle tube 13, water inlet 12, lid 14, dividing plate 15, impeller 1, helical wheel 3, turning cylinder 4, speed changer 7,8,3 dynamic sample taps 5 of variable-speed motor, adjustable overflow cylinder 6, crushing feeder 9, gives barrel 17, coarse fodder outlet 10,16 and 4 gussets 2 of fine fodder outlet.Circle tube 13 is contained in the top of cone tube 11, lid 14 is contained in the upper end of circle tube 13, dividing plate 15 is located at the centre of circle tube 13, impeller 1 and helical wheel 3 are located at the bottom of turning cylinder 4 and at a distance of 150～250cm, the upper end of turning cylinder 4 and speed changer 7 link, variable-speed motor 8 is contained on the speed changer 7, speed changer 7 is contained in and covers 14 central authorities, the lower end of turning cylinder 4 is contained in the bottom of cone tube 11,3 dynamic sample taps 5 are located at the middle part and the top of cone tube 11, adjustable overflow cylinder 6 is located at the central authorities of dividing plate 15 and turning cylinder 4 is passed from its central authorities, crushing feeder 9 is located at the top to barrel 17, be contained on the tangential direction of circle tube 13 the lower partition for the bottom of barrel 17, water inlet 12 is located at the bottom to barrel 17, fine fodder outlet 16 is located on the tangential direction on circle tube 13 dividing plate tops, and 4 gussets 2 are contained in the bottom of cone tube 11 and become 30 ° of angles with the conrotatory flow path direction of cone, and coarse fodder outlet 10 is located at the lower end of cone tube 11.Two adjustable self-rotary cyclones 21 and 22 are cascaded by pipeline 23, constitute the two-stage washing, and slag extractor 20 is located in the coarse fodder outlet of adjustable self-rotary cyclone 21 and 22, and supply-water pump 19 is connected with the water inlet of the adjustable self-rotary cyclone 21 of the first order.Consumer unit 24 and program control case 18 connect through the motor of lead with adjustable self-rotary cyclone 21 and 22, but to realize regulatory function.25 is lubricating pump among the figure.
