Block the sticking sieve of shellfish soil and the low deficiency of screening efficiency of screen perforation, high humidity for big, the flat shellfish coring of wearing and tearing that overcomes existing flat shellfish grade bolter sieve, the invention provides a kind of spiral flat shellfish grade classifying screen, this spiral flat shellfish grade classification screens out outside the function of having inherited traditional flat shellfish grade classifying screen, also has following new function: 1, in same three grades of separation that mechanically realize flat shellfish; 2, utilize the own characteristic of spiral effectively to stir flat shellfish and soil, both are separated, so that realize the screening of flat shellfish; 3, for wet sticking shellfish soil, the saturating sieve that helps flat shellfish is unlikely to flat shellfish and clings sieve aperture; 4, because the sieve aperture that spiral screen forms is dynamic, there is not stifled sieve problem in flat shellfish coring to the sieve aperture that spiral screen forms; 5, the wearing and tearing of sieve are little, the screening efficiency height.
Technical scheme of the present invention is: this spiral flat shellfish grade classifying screen comprises frame, be fixed with charging aperture on the frame, diesel engine, one deck discharging opening and two layers of discharging opening, between charging aperture and one deck discharging opening one deck compass screen surface is installed, between one deck discharging opening and two layers of discharging opening two layers of compass screen surface are installed, one deck compass screen surface and two layers of compass screen surface are formed " recessed " type by the screw rod that is arranged in parallel, twisted steel on the adjacent screw rod and groove form sieve aperture, the termination of screw rod is fixed with gear, gear on the adjacent screw rod is meshed with the sloth wheel gear of its below, be the band transmission between screw rod in one deck compass screen surface and the diesel engine, a screw rod in another screw rod in one deck compass screen surface and the two layers of compass screen surface also is the band transmission, so just realize that a diesel engine drives two-layer compass screen surface up and down, reaches the purpose that reduces power source quantity.
The present invention has following beneficial effect: owing to take such scheme, each screw rod that diesel engine rotation drives on one deck compass screen surface and the two layers of compass screen surface successively rotates in the same way, the flat shellfish and the soil that enter on one deck compass screen surface or the two layers of compass screen surface are pushed ahead under the twisted steel effect on the screw rod, twisted steel on the adjacent screw rod and groove form sieve aperture will screen flat shellfish, flat shellfish can be fallen into three classes by one deck compass screen surface and two layers of two-layer compass screen surface of compass screen surface.The present invention also has following new function except that the function of having inherited traditional flat shellfish grade classifying screen: 1, in same three grades of separation that mechanically realize flat shellfish; 2, utilize the own characteristic of spiral effectively to stir flat shellfish and soil, both are separated, so that realize the screening of flat shellfish; 3, for wet sticking shellfish soil, the saturating sieve that helps flat shellfish is unlikely to the sticking plug of flat shellfish sieve aperture; 4, because the sieve aperture that spiral screen forms is dynamic, there is not stifled sieve problem in flat shellfish coring to the sieve aperture that spiral screen forms; 5, the wearing and tearing of sieve are little, the screening efficiency height.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention; Accompanying drawing 2 be among Fig. 1 A to view; Accompanying drawing 3 be among Fig. 1 B to view; Accompanying drawing 4 is screw rod 8 structure charts among Fig. 2.
The specific embodiment:
Referring to Fig. 1 in conjunction with Fig. 2, Fig. 3, shown in Figure 4, this specific embodiment comprises frame 1, be fixed with charging aperture 2 on the frame 1, diesel engine 3, one deck discharging opening 4 and two layers of discharging opening 5, between charging aperture 2 and one deck discharging opening 4 one deck compass screen surface 6 is installed, between one deck discharging opening 4 and two layers of discharging opening 5 two layers of compass screen surface 7 are installed, one deck compass screen surface 6 and two layers of compass screen surface 7 are formed " recessed " type by the screw rod 8 that is arranged in parallel, twisted steel on the adjacent screw rod 8 and groove form sieve aperture, the termination of screw rod 8 is fixed with gear 9, gear 9 on the adjacent screw rod 8 is meshed with the sloth wheel gear 10 of its below, be the band transmission between screw rod 8 in one deck compass screen surface 6 and the diesel engine 3, a screw rod 8 in another screw rod 8 in one deck compass screen surface 6 and the two layers of compass screen surface 7 is also for being with transmission.Screw rod 8 pitch in two layers of compass screen surface 7 are less than 8 pitch of the screw rod in one deck compass screen surface 6.
During actual the use, each screw rod 8 that diesel engine 3 rotation drives on one deck compass screen surface 6 and the two layers of compass screen surface 7 successively rotates in the same way, the material that enters on one deck compass screen surface 6 or the two layers of compass screen surface 7 is pushed ahead under the twisted steel effect on the screw rod 8, twisted steel on the adjacent screw rod 8 and groove form sieve aperture will screen flat shellfish, flat shellfish can be fallen into three classes by one deck compass screen surface 6 and two layers of compass screen surface 7 two-layer compass screen surface.
When Ping Bei and soil are pasting screw rod 8 surfaces when sliding, can will attach to wash at its surperficial damp clay piece.Therefore, for wet sticking flat shellfish and soil, compass screen surface is difficult for producing sticking sieve aperture phenomenon after sieving.In addition in screening during material, material always is in screw rod 8 radially on the diverse location, when screw rod 8 rotations, because the linear velocity of material has nothing in common with each other, thereby makes material realize loose sieve.Such operation principle, the device that uses the vibration class to screen flat shellfish with tradition is essentially different.The vibration class screening plant that tradition is used is by vibrating screen surface material to be thrown, layering is sieved thoroughly, wet when being stained with material when running into, the easiest knot cake of powder interlayer near compass screen surface, stop up sieve aperture, saturating sieve is difficulty very, particularly 8,10, the sieve aperture of 13mm small dimension, stifled sieve is more serious, just can't realize sieving and grading, in addition at all, flat shellfish and soil also are to result from the incline sliding force of material back material self gravitation of compass screen surface toward the power of front slide, reach is just very passive and slow, inefficiency, and this kind equipment belongs to passive screening.The present invention is the rotation by screw rod 8, the pressure material advances, sieve aperture is dynamic translation sieve aperture, unblocked, therefore have high efficiency, the moving screening of owner, because constituting adjacent two screw rods 8 of sieve aperture is opposite in the linear velocity direction that forms the sieve aperture projecting direction, it is mobile that flat shellfish is subjected to a pair of force couple role to form rolling, plays the effect of removing flat shellfish coring, therefore do not have the generation that broken situation generation of flat shellfish and coring block up the sieve phenomenon.
In sum, the present invention also has following new function except the function of having inherited traditional flat shellfish grade classifying screen: 1, in same three grades of separation that mechanically realize flat shellfish; 2, utilize the own characteristic of spiral effectively to stir flat shellfish and soil, both are separated, in order to realize the screening of flat shellfish; 3, for wet sticking shellfish soil, the saturating sieve that is conducive to flat shellfish is unlikely to the sticking plug of flat shellfish sieve aperture; 4, because the sieve aperture that spiral screen forms is dynamic, there is not stifled sieve problem in flat shellfish coring to the sieve aperture that spiral screen forms; 5, the wearing and tearing of sieve are little, the screening efficiency height.
