Abstract
A rectilineal vibrating screen with banana-shaped multiple section screening surface is designed for the shortage that: the flow rate of materials on the prior vibrating screen with multiple section screening surface changes unexpectedly, causing serious abrasion for the screening surface part, no obvious layer for the big and small particles, not complete leaking screen, and relative less throughput. The whole screening surface comprises 4 to 8 sections of screening surfaces with different dip angles, the included angle between screening surface and the water level is arrayed by the stepped decreasing type from a material inlet end, the layer number of the screening surface is from one layer to a plurality of layers, the relative fine materials always approaches the screening surface, the thickness of each section of the material layer is uniform, the layer of big and small particles is obvious, the screening effect is good. The utility model can be used for the grading work for undersize, and the work for dewatering, desliming, and de-mediating for the materials.
Description
Technical field the utility model relates to the vibration screening machinery field, can keep the uniform banana-shaped multistage of the thickness of feed layer of material on the compass screen surface compass screen surface linear vibrating screen that is sized.
Background technology is the straight line equal-thickness vibrating screen of operation at present, because sieve nest is longer, move not steadily, and it is big to take up an area of the space, easy plug-hole, and treating capacity is less relatively.As the equal-thickness vibrating screen at 2-3 section inclination angle, because material flow changes suddenly, be prone to material in two compass screen surface junctions and assemble, cause compass screen surface concentrated wear phenomenon serious, influence screening efficiency, reduce the compass screen surface life-span.
Utility model content the utility model provides a kind of banana-shaped multistage compass screen surface linear vibrating screen, and when its material moved on compass screen surface, the size particles material layering was obvious, and thickness of feed layer is even, and screening efficiency is higher, and treating capacity is big.
The utility model is realized by following measure, vibratory sieve is made up of compass screen surface, screen frame, vibrator, transmission device and vibration damping base, whole compass screen surface is made up of the folding face of 4-8 section different angle, the compass screen surface number of plies by one deck to multilayer, the inclination angle of compass screen surface is value between 5 ° to 40 °, it is that the mode of successively decreasing is step by step arranged that the angle of compass screen surface and horizontal plane begins from feeding end, and the translational speed of material from fast to slow.Compass screen surface also can be the camber line shape compass screen surface recessed down that successively decreases gradually and forms by begin curvature from feeding end.Whole section compass screen surface camber line is evenly smooth, shape such as same well-done banana.If be used for graded operation, what the compass screen surface sieve aperture adopted is rectangular opening, and the length-width ratio of rectangular opening is successively decreased along with successively decreasing of compass screen surface angle.During the vibratory sieve operation, different separately movement velocitys and different impelling intensity take place in material on each section compass screen surface, remain thinner material near compass screen surface, and speed slows down gradually, and reaches desirable screening effect.
The utility model has the advantages that, because adopting the compass screen surface of multistage different angles forms, make the material size particles layering on the vibratory sieve obvious, thickness is even, saturating sieve thoroughly, it is big to have treating capacity, and screening efficiency is high and occupy the little characteristics in space, can be applicable to the operations such as dehydration, desliming, de-mediated of more graded operation of undersize material and material.
Appended drawings is the structural representation of five sections compass screen surface vibratory sieves of the utility model, and 1-5 is that five sections compass screen surfaces, 6 are that the eccentric external vibrator of piece, 7 is that transmission device, 8 is that screen frame, 9 is the vibration damping base device among the figure.
The embodiment that this use of specific embodiment accompanying drawings is novel, screen frame 8 is fixing by vibration damping base device 9, is provided with eccentric block external vibrator 6 above screen frame 8.The angle of five sections compass screen surface 1-5 and horizontal plane is arranged in the mode of successively decreasing gradually from feeding end.The angle of compass screen surface 1 is that 25 °, the angle of compass screen surface 2 are that 20 °, the angle of compass screen surface 3 are that 15 °, the angle of compass screen surface 4 are that 10 °, the angle of compass screen surface 5 are 5 °.When being used for graded operation, the length-width ratio of compass screen surface sieve aperture was reduced to 1: 1 gradually from 4: 1.
