The material that enters by charging aperture 1 and directly enter one-level screen drum 5 in the one-level separation bin 6 by the wind that blast pipe 2 is sent into; Secondary screen drum 7 in the secondary separation bin 8 is greater than one-level screen drum 5; Three grades of screen drums 9 in three grades of separation bins 10 are greater than secondary screen drum 7; Discharge pipe 12 connects metal cylinder 4, is positioned at after the fourth stage separation bin; The absolute altitude of discharge pipe 12 upper edges is identical with metal cylinder 4, and its lower edge is an arcwall face, and the arc length of the lower curve of its axial section is 1/8～1/6 of a whole circumference girth; Discharge pipe 12 links to each other with whirlwind tube 13, and its bottom is provided with the discharging opening 17 of a collection lightweight combustible.
The sieve aperture of one-level screen drum 5, secondary screen drum 7, three grades of screen drums 9 is a helical form bar seam, and its size is preferably 5mm, 10mm, 30mm (or 40mm) respectively; Three grades of screen drums all are parallel to metal cylinder 4, and metal cylinder 4 is 3～8 ° with the angle of horizontal plane.
In a preferred embodiment, the steel roller is installed in metal cylinder 4 bottoms of each separation bin, and the steel roller is placed in (not shown) on the steel rail groove.
In charging aperture 1 and blast pipe 2 one sides, metal cylinder 4 is set to a mobilizable sealed door, and student's end and discharge pipe 12 places all are provided with a maintenance manhole; Metal cylinder, screen drum, separation bin, manhole, charging aperture, blast pipe, discharge pipe connection fittings each other all adopt screw, pull and buckle and sealing strip.By behind the reductor 18 connection motors 19, by belt or 15 rotations of gear band driving wheel band, wheel is with 15 by backing roll 14 supports during screen drum work; The direction of rotation of secondary screen drum 7 and one-level screen drum 5, three grades of screen drums 9 is identical.
2 three grades of separation bin combined types of embodiment separator
As shown in Figure 7, be the combined type separator of three grades of separation bins, basic identical with the structure of the combined type separator of level Four separation bin, difference only is that screen drum quantity is 2, has omitted the third level separation bin 10 and the third level screen drum 9 of level Four separation bin.
In the first order separation bin 6, the sieve aperture specification of screen drum 5 is preferably 5mm; In the second level separation bin 8, the sieve aperture specification of screen drum 7 is preferably 30mm or 40mm.According to needs of production, the sieve aperture specification of corresponding adjustment is also within category of the present invention.
The separation of embodiment 3 regeneration coarse-fine aggregates
Combined type separator with the level Four separation bin is an example, and reductor 18 connects motor 19 and drives metal cylinder, screen drum rotation.Enter the regeneration aggregate of screen drum 5 from charging aperture 1, rise along the inwall of rotation screen drum 5, loose falling after rising to certain altitude, so repeatedly.The regeneration aggregate that enters continuously in the screen drum 5 is subjected to the friction in intergranular friction, particle and helical form wedge wire screen hole and the effect of pressure and material loosening, progressively moves to the outlet of screen drum 5 other ends.In this course, spill by sieve aperture, discharge from the discharging opening 16 that is arranged on metal cylinder 4 bottoms less than the regeneration aggregate of sieve aperture; Aggregate greater than sieve aperture is brought to the other end of screen drum 5 along with screen drum 5 rotations, thereby enters next screen drum 7 of next separation bin 8, so repeatedly, and until finishing separation.The coarse aggregate of last separation bin 11 can be discharged as required or circulate and be entered disintegrating apparatus.
The separation of embodiment 4. lightweight combustibles
The wind that is produced by air blast 3 enters in the one-level separation bin 6 from blast pipe 2, is subjected to the influence of screen drum 5 rotations, and this strand wind forms a barotropic disturbance air-flow.The lightweight combustible that is mingled in the regeneration aggregate is being rotated the moment that falls after screen drum 5 takes up, powerful air-flow just is blown into it next separation bin 8, so repeatedly, after entering discharge pipe 12, run into the arc sphere, windage increases, and the lightweight combustible is discharged along arc sphere discharging opening 17 from here under the deadweight effect, is collected after the dust that blows afloat with the lightweight combustible enters whirlwind tube 13.
The present invention has following beneficial effect:
1. reduce the moisture content of regeneration aggregate
Enter the regeneration aggregate of Combined separating device, along with the screen drum that rotates does not stop rolling, increased aggregate and the contact area that blasts wind, take away after most of moisture is evaporated, realize reducing moisture about 2～6%. In addition, when the wind that is blown into Combined separating device when air blast was 100～300 ℃ low temperature hot blast, the moisture content of regeneration aggregate reduced amplitude and will increase, and can reach the purpose of oven dry.
Regeneration coarse-fine aggregate the separative efficiency height, effective, production capacity is big
Part can be in being separated at the very start when screen drum rotates less than the regeneration aggregate in screen drum aperture, and for the fine aggregate in being mixed in coarse aggregate, when the rotation screen drum takes up aggregate to extreme position, when falling, it will carry out to a certain degree impact to screen drum, thereby can effectively prevent sieve pore blockade, improve separative efficiency and separating effect, enlarged simultaneously production capacity.
3. separation of lighter combustible fully
The lightweight combustible that is mingled in the regeneration coarse-fine aggregate passes through the in twos reverse rotation effect of screen drum, and in conjunction with powerful wind-force effect, it can be separated from aggregate like a cork. The arc spherical structure of discharge pipe place uniqueness can be realized the collection of lightweight combustible.
4. simple in structure, durable in use
Combined separating device is the ingenious combination of a plurality of separation bins, a plurality of screen drum and wind-force, and separation bin can freely connect and separate in twos, and is therefore simple in structure; Impulsive force when the structural strength of screen drum can fall according to the carrying aggregate customizes, and screen drum rotation at work is stressed evenly, and the lightweight combustible can not hang on the screen drum, therefore is not easy to damage.
5. easy to maintenance
The connection fittings of Combined separating device substantially adopt screw, pull and buckle and sealing strip, so dismounting is all very convenient; Its front and back end is provided with the maintenance manhole, and usual maintenance is entered by manhole; When needs are changed screen drum, then can be entered by the movable sealed door of front end, so maintenance operation is convenient.
6. powerful, and energy-saving and environmental protection
That Combined separating device is integrated is air-dry, grading, separation of lighter combustible, a series of functions such as gather dust. The arcwall face structure of separation bin discharging opening place uniqueness has reduced air resistance coefficient effectively, has increased the utilization rate of wind-force, has reduced energy loss; The arcwall face structure at discharge pipe place makes lightweight combustible and dust separation effectively, and cyclone cylinder is collected dust effectively. Therefore this is that a cover is powerful, and the device of energy-saving and environmental protection.
