Description
Technical field:
The present invention relates to screening plant, relate in particular to a kind of multi-layer multi-function electric screen grader.
Background technology:
When carrying out material screening now, generally be that sieve is erected, material to be sieved is sprinkling upon on the sieve, make material landing on sieve, manually to sieve.Some electric screen graders are also arranged, or adopt centrifugal screening, or adopt the oscillatory type screening but all exist structure too simple, the problem that screening effect is bad, the then structure that has are too complicated, and the cost cost is too high, does not have actual operation.Chinese patent 90213996.7 discloses a kind of motor-vibro screen, utilizes eccentric wheel to drive the sieve vibration and sieves.But it is simple in structure, and sieve material down need artificially collect, and outsifting can't be recycled, and labour intensity is big, and the screening machine of prior art only can carry out individual layer and sieve, and screening effect is not ideal enough.
Summary of the invention:
The objective of the invention is to, overcome the deficiencies in the prior art part, provide a kind of rational in infrastructure, easy to use, can carry out multi-stage screening, screening effect is good, and labour intensity is little, safe and reliable multi-layer multi-function electric screen grader.
Multi-layer multi-function electric screen grader of the present invention includes frame, hopper, movable screen frame (unit), feed back plate, motor, eccentric wheel and interlock connecting lever and forms.Said frame is the wire support member of multi-function electric screen grader of the present invention.Integral body is frame structure, can be welded with angle steel or channel-section steel.On frame, be provided with hopper.Said hopper is up big and down small inverted trapezoidal structure, is charging aperture above, is discharging opening below, is provided with movable screen frame (unit) in frame.Said movable screen frame (unit) can be provided with several layers of sub-sieve as required, generally is advisable with three layers.Ground floor carries out scalping, and the second layer carries out dusting cover, and the 3rd layer is carried out fine screen, in the bottom of screen frame (unit), is provided with the sieve end below promptly bottom one deck sub-sieve.For improving screening effect, the sub-sieve on the said movable screen frame (unit) all is set to the inclination form at certain angle of inclination.One end of said movable screen frame (unit) is set to closing form, and the high-end sealing of movable screen frame (unit) just is connected with the sub-sieve discharge port on each layer of low side sub-sieve of the other end.Sub-sieve low side at ground floor is provided with upper strata sub-sieve discharge port, is provided with middle level sub-sieve discharge port at the sub-sieve low side of the second layer, is provided with lower floor's sub-sieve discharge port at the 3rd layer sub-sieve low side.Said middle level sub-sieve discharge port adopts the form that draws off forward, and upper strata sub-sieve discharge port and lower floor's sub-sieve discharge port then are arranged to the form that draws off to both sides.On said movable screen frame (unit), be respectively arranged with the feed back plate below ground floor and the second layer sub-sieve, said feed back plate be arranged on movable screen frame (unit) below, be the relative tilt state with movable screen frame (unit), that is to say, the low side of movable screen frame (unit) connects the high-end of feed back plate, and in other words, just the sub-sieve on feed back plate and the movable screen frame (unit) is the form that is provided with of " Z " font.For ease of connecting material the arrangement straggly of said discharge port.Lower position at the bottom of the lowermost sieve of movable screen frame (unit) also is provided with the screenings discharging opening with the arrangement straggly of sub-sieve discharge port.Be provided with motor below frame, the back of frame is provided with eccentric wheel, and eccentric wheel is connected with the rear end of movable screen frame (unit) by the interlock connecting lever.
When using multi-function electric screen grader of the present invention, the motor drives eccentric wheel rotates, eccentric wheel makes screen frame (unit) produce vibration by the interlock connecting lever, material is in hopper falls into ground floor sub-sieve on the screen frame (unit), and after the scalping of first order sub-sieve, oversize draws off from ground floor sub-sieve discharge port, screenings drops on the following feed back plate, by the feed back plate, the screenings after the scalping drops on the high end position of second layer sub-sieve, carries out second level dusting cover.Behind the dusting cover of the second level, oversize draws off by the middle level sub-sieve discharge port that staggers with ground floor sub-sieve discharge port, and screenings drops on the following feed back plate, by the feed back plate, drops on the 3rd layer high-end again and carries out fine screen.Draw off by lower floor's sub-sieve discharge port that the sub-sieve discharge port with the ground floor and the second layer staggers respectively through the oversize after the fine screen.Screenings falls into the sieve end, draws off from the screenings discharging opening, can finish the operation sequence of screening.
Multi-function electric screen grader of the present invention can be adjusted mesh order number as required, just selects the screen cloth of different meshes for use, and simultaneously material is carried out multi-stage screening.Easy to use, safe and reliable, when using multi-function electric screen grader of the present invention, pocket can be placed on sub-sieve discharge ports at different levels and the screenings discharging opening, finish screening operation automatically, can obviously reduce labour intensity.Material through sub-sieves at different levels can reclaim respectively.Owing to adopted the feed back plate structure, material slides to low side from the high-end of sub-sieves at different levels, has improved screening effect greatly.
