Description
Technical field
The present invention relates to a kind of sieve, especially relate to a kind of double-deck roto-siofter.
Background technology
Now general roto-siofter be one columnar structured, circular framework has some pieces of curved screens form, by the rotary motion of driven by motor cylinder screen, the particle being less than sieve aperture is sifted out, thus reaches the object of particle screening.Roto-siofter mainly contains mechanism's compositions such as motor, reductor, drum apparatus, frame, and drum apparatus is in being in tilted layout.Motor, through reductor, links together with cylinder mechanism, and head roll mechanism rotates around its axis.After material enters drum apparatus, due to inclination angle and the rotation of drum apparatus, qualified material is discharged through the screen cloth of cylinder cylindrical, and screening materials carrying is discharged through cylinder end.Roto-siofter drum apparatus is by body seal cap sealing, thus the equipment of guarantee in the course of the work, effectively prevents dust from escaping, stop dust pollution.When changing screen cloth, only body seal cover need be opened namely replaceable, easy to operate.But such roto-siofter equipment purposes is single, structure falls behind, and is not suitable with high accuracy modern production needs, particularly require sieving doses comparatively greatly and particle diameter difference is less time, the screening effect of above-mentioned sieve is poor, is difficult to reach expection screening effect.
Summary of the invention
in order to overcome the deficiency in background technology, the invention discloses a kind of double-deck roto-siofter, carrying out a series of improvement in screening principle, structure etc., the purposes of sieve is wide, and screening effect is good.
In order to realize described goal of the invention, the present invention adopts following technical scheme: a kind of double-deck roto-siofter, is fixed on supporting seat, comprise shell, outer sieve and interior sieve, interior sieve is arranged on the internal layer of outer sieve, and shell is arranged on the outside of outer sieve, and the sieve plate of outer sieve and interior sieve is provided with sieve aperture.The inside of described interior sieve arranges some arc liner plates, and interior sieve is close to by arc liner plate, and adjacent two arc liner plates head and the tail are affixed and surround the cylindrical shape identical with interior sieve; Wherein one end of each arc liner plate and the inwall ledges of interior sieve are connected through the hinge, the other end is movable, in interior sieve cylinder rotary course, arc liner plate is along with rotation, and end falls gradually, vertically falls to high point, screening materials carrying is fallen again by Action of Gravity Field, realize screening again, avoid sieve pore blockade, screening effect is better.
Outer sieve of the present invention is made up of some camber parts, every adjacent arcs shaped piece cylindrical shape surrounded that joins end to end is sieved outward, and described interior sieve is cylindrical shape, with outer sieve concentric circles each other, outer sieve and interior sieve are fixed in rotating shaft simultaneously, and rotating shaft is connected with reducing motor by driving chain.
Camber part of the present invention is involute shaped piece, and the involute direction of described involute shaped piece is consistent with the direction of rotation of sieve.
The tail end of involute shaped piece of the present invention sets up lifting blade.
The inside of double-deck roto-siofter of the present invention is also provided with vibrating device.
The mesh size of outer sieve of the present invention is identical with the mesh size of interior sieve.
Camber part of the present invention is 6-8 block.
Owing to have employed technique scheme, the present invention has following beneficial effect: the camber part of outer sieve is designed to involute-type camber part by original positive circular arc type part, the circular arcuate member area of involute camber part area ratio is large, extend the sieving time of material at compass screen surface, thus raising screening efficiency, each block involute-type camber part tail end design lifting blade, the material that lifting blade drives not sieved to fall rotates with cylinder, involute-type camber part is rotated and is raised in the process of high point, screening materials carrying gravitate falls, due to speed and gravity double action, material falls again, screening effect is better, solve again outer sieve sieve pore blockade problem, along with the continuous revolution of roto-siofter is rotated, partial material is brought to again the top of sieve, gravity is relied on to scatter interior sieve top, second time screening is carried out to material.The fines sieved is fallen in interior sieve, outer sieve is again fallen into for preventing fines, liner plate is set up at interior sieve internal layer, liner plate shape is the same with sieve plate, one end adopts hinge type to fix together with sieve plate, along with roto-siofter upwards rotates, liner plate is slowly opened, and when forwarding top to, liner plate is all opened, after the partial material that liner plate drives crosses top, by Action of Gravity Field, material falls, and solves the sieve pore blockade problem of screening plant, liner plate is slowly fallen again on sieve plate, overlap with sieve plate when forwarding bottom to, thus screened material is collected, so move in circles.Outer sieve is in the process of screening, the camber part of outer sieve is designed to involute-type camber part by original positive circular arc type part, increase camber part sieving area, each block involute-type camber part tail end design lifting blade, extend the sieving time of material at compass screen surface, the material that lifting blade drives not sieved to fall rotates with cylinder, every block involute-type camber part is rotated and is raised in the process of high point, screening materials carrying gravitate falls, due to speed and gravity double action, material falls to having speed and strength, screening effect is better, solve again outer sieve sieve pore blockade problem, along with the continuous revolution of roto-siofter is rotated, partial material is brought to again the top of sieve, gravity is relied on to scatter interior sieve top, second time screening is carried out to material, sieve aperture is cleared up, improve screening efficiency.
