Abstract

The utility model relates to a novel corrugated sieve, comprising a screen frame, a platen and a corrugation sieve deck. The screen frame is fixedly welded by four channel sections and is a rectangular frame. The sieve frame is welded by three steel plates. The bottom margin is fixedly welded with the outer margin of the three sides of the screen frame. The discharging opening at one side of the opening is fixedly welded with the screen frame. The inner of the lower part of the sieve frame on the three sides is welded with weight at equal distance. The lower part of the screen frame is fixedly welded with four same cross beams. The screen frame is rectangular frame welded by angle steels. Two reinforcements are arranged in the longitudinal direction. The corrugation sieve deck is in corrugation type. The lowest point of the trough is consistent with the flat surface of the edge. The peak is above the flat surface of the edge and the both ends of the peak are plough-shaped seals. Screen apertures are equispaced on the trough, the peak and the flat surface on the four sides. The bottom margin of the screen frame is matched with the surface of the screen frame. The platen is provided with light apertures. The bolt is fixed with the light apertures on the sieve frame through the light aperture on the platens. The corrugation sieve deck is matched with the sieve pressing wood by the three sides of the sieve frame. The upper surface and the lower surface of the wedge and the sieve pressing wood are matched and fixed to the corrugation sieve deck. The corrugation sieve deck adopting the corrugation shape can sufficiently flip bulk material, enlarges the sieving area and has obvious sieving effect.

Description

A kind of novel ripple sieve

Affiliated technical field

The utility model relates to the sieve plate that a kind of sieving machine uses, and especially can help the Wave screen plate technology of material loosening.

Technical background

At present, the sieve plate of sieving machine use all is a flat shape.The vertical tremor of sieving machine and have certain gradient makes the material that is sized do bob on sieve plate and advances, and material is loose in the process that bob advances, the size particles transposition, and the granule motion causes sieve plate, and it is separated to pass the sieve plate hole.Use the sieve plate of flat shape can only play the effect that holds up material at present, material loosening is not had help, be unfavorable for strengthening screening operation, the loose of material can only rely on the vibrations of machinery loose naturally.Material movement resistance less than sieve aperture in screening process mainly is those materials greater than sieve aperture, and those big materials form the bulky grain layer on sieve plate usually, hinders little granule materials and moves to sieve plate, and screening efficiency is reduced.And because the restriction of sieving machine, the sieving area of sieve plate is restricted, and energy discharging is than undesirable.

Summary of the invention

Do not help the loose of material and screening in order to overcome existing sieve plate, in screening process, can not play the loose effect of stirring to material, and energy discharging is than unfavorable deficiency, the utility model provides a kind of sieve plate of novel bellows-shaped, being sized material is upwards beated to crest by trough, because the variation of spatial area, material can obtain fully loose, material travels forward on sieve plate, dislocation through the joint of several sieve plates Wave crest and wave trough is played tipping effect to material, owing to adopt bellows-shaped, the area of material contact is the area that launches, and has increased the effective sifting area of sieving machine.

The utility model is that the technical scheme that its technical barrier of solution is taked is by screen frame (unit), pressing article, Wave screen plate constitutes, screen frame (unit) is by suitable beam, sieve group, foundary weight, crossbeam, discharging opening is formed, screen frame (unit) is by four rectangular frames of channel-section steel diagonal angle solid welding, vertically be welded with the six roots of sensation in the frame along beam, two channel-section steels are one group dorsad, meet between channel-section steel, sieve group is by three block plates weldering system, the outside, upper edge is welded with reinforcement, three outer rim solid weldings of base and screen frame (unit), discharging opening of opening and screen frame (unit) solid welding, three sieve group lower inside equidistantly are welded with foundary weight, the crossbeam solid welding that the screen frame (unit) bottom is identical with four, sieve plate is by screen frame, Wave screen plate is formed, screen frame is the rectangle frame of angle bar weldering system, two lacing wires are laterally arranged, Wave screen plate is a corrugated, there is flat edge at the four sides, the both sides flat edge of longitudinal ripple is wide plane and narrow plane, unthreaded hole is arranged, the trough minimum point is consistent with the plane, limit, crest exceeds the plane, limit, the crest two ends are that plow-shape seals trough, crest and four limit plane surfaces are evenly equipped with sieve aperture, and Wave screen plate cooperates solid welding to constitute sieve plate with screen frame, screen frame base and screen frame (unit) surface engagement, pressing article is made by the steel plate bar, and unthreaded hole is arranged on the pressing article, pressing article and Wave screen plate side seam surface engagement, push down Wave screen plate intermediate gap and discharging opening one end margin, bolt is fastening through unthreaded hole on the pressing article and the unthreaded hole on the screen frame (unit), and Wave screen plate cooperates with pressing sieve wood by three limits of sieve group, and the timber wedge top and bottom are with foundary weight and press sieve wood to cooperate fixedly Wave screen plate.

The beneficial effects of the utility model are to take the sieve plate of bellows-shaped can fully stir bulk material, and have strengthened sieving area, and screening effect is obvious.
