Shown in composition graphs 3,4,5, belt conveyor 12 comprises upper and lower two-layer transportation section, the below being positioned at the belt conveyor 12 of transportation section, upper strata is provided with many turning cylinders 20, and turning cylinder 20 is arranged on the second support 11 by bearing block, by sprocket wheel 21 and chain 22 transmission between turning cylinder 20.Be fixed on the second motor 23 on the second support 11 to be connected with a wherein turning cylinder 20 by shaft coupling, like this when startup the second motor 23, all turning cylinders 20 can rotate.Each turning cylinder 20 is fixed with multiple rotation evenly and at intervals and dials device, described rotation is dialed device and is comprised a connecting plate 24 and a holder, holder is the first axle sleeve 31 of a flanged dish 32, first axle sleeve 31 aperture is identical with the diameter of turning cylinder 20, first axle sleeve 31 is also provided with jackscrew screw, the inner surface of the first axle sleeve 31 has the keyway axially identical with turning cylinder 20, the middle part of connecting plate 24 has a circular hole, the periphery of circular hole is provided with multiple through hole be evenly arranged, and the two ends of connecting plate 24 are respectively provided with a screwed hole.Connecting plate 24 passes through from circle hole sleeve with it on the first axle sleeve 31, make the screw on ring flange 32 relative one by one with the through hole on connecting plate 24, be fixed on the first axle sleeve 31 by screw bolt and nut by connecting plate 24 afterwards, the screwed hole at connecting plate 24 two ends is fixed with a roller 25 respectively by screw bolt and nut.Turning cylinder 20 is provided with flat key vertically, is enclosed within turning cylinder 20 by the first axle sleeve 31, and the flat key on turning cylinder 20 is positioned at the keyway of the first axle sleeve 31, and the first axle sleeve 31 is fixed on turning cylinder 20 by the jackscrew 33 being arranged in jackscrew screw afterwards.Adjacent two connecting plates 24 on same turning cylinder 20 are mutually vertical, also mutually vertical along adjacent two connecting plates 24 in belt conveyor 12 direction on adjacent two turning cylinders 20, the object so arranged is in order to rotation can be made to dial belt conveyor 12 that device beats transportation section, upper strata more equably.
Shown in composition graphs 6,7,8, in order to material loading is convenient, the present invention also comprises a carrier bar feeder 26, carrier bar feeder 26 is prior art, it mainly comprises: motor, drive sprocket, driven sprocket, carrier bar and support roller, motor drives drive sprocket to rotate, and drive sprocket drives carrier bar to rotate to transport material.The discharging opening of carrier bar feeder 26 is positioned at the top of rod parabolic separator, and in order to material can be made successfully to enter on bar screen 2, the top of bar screen 2 is also fixed with a slide carriage 29, and described slide carriage 29 is fixedly located on the baffle plate 4 of Bar strip type vibratory sieve.
Introduce the course of work of the present invention below:
Use loading machine that rubbish to be processed is put on carrier bar feeder 26, rubbish is fallen the slide carriage 29 of rod parabolic separator from the discharging opening of carrier bar feeder 26, rubbish enters on bar screen 2 under the effect of self gravitation, and the effect of vibration due to bar screen 2 makes the fritter weight in rubbish and the light thing of strip fall from the gap of rod.If fritter weight and the light thing of strip drop on upper end or the lower end of the belt conveyor 12 of bouncing separation conveyor, bouncing separation conveyor does not all have the sufficient time fritter weight and the light thing of strip to be separated, so fritter weight and the light thing of strip can only be made to fall the middle part of belt conveyor 12, they could be separated like this.In order to achieve the above object, be fixed with screenings chute 27 and screenings baffle plate 28 at the lower surface of bar screen 2, screenings and fritter weight and the light thing of strip move downward along screenings chute 27 and drop to the middle part of belt conveyor 12 in the effect of screenings baffle plate 28.Under the effect of device is dialed in rotation, fritter weight enters into the 3rd belt conveyor 19 from the lower end of belt conveyor 12, and the light thing of strip hangs on driving lever 16, enter into the second belt conveyor 18 from the upper end of belt conveyor 12 under the effect of driving lever 16, this completes the separation between fritter weight and the light thing of strip.
In rubbish except the fritter weight under can being sieved by bar screen 2 and the light thing of strip, also have the light thing of bulk and bulk weight can not be sieved down by bar screen 2, and the light thing of bulk and bulk weight also to complete and be separated from each other.Under the effect of vibration of bar screen 2, hang over bar on rod and the light thing of bulk enters into the light thing chute 8 of bulk from the bulk light thing outlet 6 of bar screen 2 lower end, then enter on the first belt conveyor 9 through the light thing chute 8 of bulk.Bulk weight then drops on bulk weight chute 1 in the effect of bar screen 2, then enters in bulk weight holding tank 10 through bulk weight chute 1.So also just complete the mask work between the light thing of bulk and bulk weight.
In order to ensure the separating effect of rod parabolic separator, gap between rod is general larger, due to the effect of vibration of bar screen 2, fritter weight and the light thing of strip are fallen on the belt conveyor 12 of bouncing separation conveyor with mutual NA state, are conducive to bouncing separation conveyor like this and are separated it.Two kinds of screening installations combine by the present invention, have both given full play to the advantage of every platform equipment, have overcome again the weak tendency of single equipment.For not needing smart fine-sorted rubbish, being used alone the present invention and just can achieving the goal; For the smart fine-sorted rubbish of needs, the present invention can realize the ragging to rubbish, for next step meticulous sorting is ready, this makes it possible to the wearing and tearing reducing equipment in next procedure, improves its service life.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
