The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that not conflicting, the feature in the present embodiment and embodiment can be combined mutually.
Fig. 1 is the schematic diagram of the roto-siofter in the utility model embodiment, and in Fig. 1, the direction of arrow is that material moves towards direction.Fig. 2 is the schematic diagram of the roto-siofter in the utility model embodiment, and in Fig. 2, the direction of arrow is the direction of rotation of screen drum 2.See shown in Fig. 1 and 2, the roto-siofter of the utility model embodiment comprises housing 1 and screen drum 2, screen drum 2 is arranged in housing 1, housing 1 is provided with feed opening 7 and slag notch 5, also comprise baffle ring 3 and a material shovel 4, baffle ring 3 is circular, and baffle ring 3 is fixed on the inner side of screen drum 2 slag output ends, the inner side that can welding manner be fixed on screen drum 2 slag output ends, baffle ring 3 is for stopping the material that enters screen drum 2 slag output ends.
Material shovel 4 comprises the screen cloth 9 with cambered surface, material shovel 4 is fixed on the inner side of baffle ring 3, can be welded on baffle ring 3 inner sides, cambered surface respectively with the Plane intersects of arc surface and the baffle ring 3 of screen drum 2, the direction of rotating along screen drum 2, material shovel 4 extends to internal circle with the arc limit of baffle ring 3 Plane intersects from baffle ring 3 outer circumferential edge.In screen drum 2 rotary courses, material shovel 4 is the material that scoops up screen drum 2 afterbodys and accumulate, and 9 pairs of material shovel 4 materials that scoop up of screen cloth filter, and unfiltered large granular materials is directed to slag notch 5.As preferred embodiment, cambered surface is preferably vertical with baffle ring 3 planes, and unfiltered like this large granular materials is directed to slag notch 5, and small particle is not easy to be taken out of.
As shown in Fig. 2,3,4 and 5, material shovel 4 adopts the screen cloth 9 of triangular-arc, and the summit of a wedge angle of material shovel 4 is positioned at the junction of baffle ring 3 inner sides and screen drum 2.The screen cloth 9 of material shovel 4 for being bent to form by leg-of-mutton screen cloth face, the preparation method of material shovel 4 is: be first made into triangle, so posterior bow is made screen cloth 9, also can adopt other preparation method.
As disposable enforcement examination, material shovel 4 also can adopt the screen cloth of other shape with cambered surface, as the screen cloth of four jiaos of arcs, also can first make dimetric screen cloth, and so posterior bow is made.
Material shovel 4 also comprises the fringing 10 that wraps up screen cloth edge; and screen cloth edge is fixed in fringing 10, fringing 10 not only can strengthen the bulk strength of screen cloth like this, prevents screen cloth distortion; protection screen cloth marginal laceration or breakage, and can conveniently screen cloth be fixed on baffle ring 3.Fringing 10 can adopt metal material, as steel fringing 10.
As disposable embodiment, described roto-siofter is also provided with a plurality of material shovels 4, and a plurality of material shovels 4 are fixed on the inner side of baffle ring 2 successively, further preferably, three material shovels 4 can be set.
First the lower sides of slag notch 5 is offered to a side mouth, then the side mouth place of slag notch 5 is provided with double-edged fine-toothed comb 6, double-edged fine-toothed comb 6 can be the several round steel in slag notch 5 interior welding, roto-siofter also comprises powder conveying apparatus 8, powder conveying apparatus 8 can adopt the conventional powder conveying apparatus using, as carried reamer.Powder conveying apparatus 8 can be connected with feed opening 7, and the below of double-edged fine-toothed comb 6 is communicated with powder conveying apparatus 8.To flowing into the material of slag notch 5, carry out screening again like this, after screening choosing, material enters again powder conveying apparatus 8, strengthens screening effect.
For the convenient waste material that stores, slag notch 5 can be connected with garbage collection tank.
The course of work of the utility model roto-siofter is as follows:
Powder is entered in screen drum 2 by charging aperture, in screen drum 2 rotation processes, most of powder sees through sieve aperture and falls into discharging opening, another part flows into screen drum 2 afterbodys and is blocked by baffle ring 3, with screen drum 2, rotate by material shovel 4 and scoop up, bulky grain waste streams turnover cinder notch 5 wherein, short grained falling into again in screen drum 2, and so forth, thereby makes material screening more abundant.The material that waste material enters slag notch 5 directly drops on double-edged fine-toothed comb 6, and the granule that waste material is mingled with sees through double-edged fine-toothed comb 6 and enters reamer, and the waste material that granularity is large flows to garbage collection tank along dirt-excluding groove, thereby realizes the postsearch screening of material, has increased the utilization rate of material.
