Abstract
A method for screening material by a dedicated electromagnetic vibration sieve includes such steps as feeding material onto the sieving net inclined by +/- 15 degree, moving the sieving net for conveying material while sieving it, and turning-on an electromagnetic vibration exciter attached to said sieving net for vibration screening. Said dedicated electromagnetic vibration sieve is also disclosed.
Description
Technical field:
The present invention relates to a kind of solid separating screening method and equipment of industrial use, particularly sieve the method and the special-purpose electromagnetic vibrating screen of material with electromagnetic vibrating screen.
Background technology:
Screening operation is to use a kind of very widely operating type in industries such as coal, metallurgy, cement, pottery, building materials, food processing.Present employed screening plant mostly is vibrating formula and complete machine oscillation formula.In the structure of complete machine oscillation formula, screen cloth and screen box are fixed together, and screen box and screening mechanism vibrate simultaneously during screening operation.Because the screen box ginseng is shaken, and needs bigger exciting force, easily cause screen box or other drive disk assembly to damage, cause the increase of maintenance of equipment amount and reduce service life.In addition, the mechanical vibration force that complete machine oscillation formula screen(ing) machine is passed to ground is very big, and is high to the bearing capacity requirement of ground.Vibrating formula structure is separated screen cloth with screen box, exciting force is directly passed to screen cloth, has reduced to join shake parts and weight, and power consumption reduces, and the life-span of equipment prolongs relatively.In the prior art, vibration sieve often adopts fixed screen cloth, and compass screen surface and horizontal plane have bigger inclination angle.Because screen cloth and material have very big relative displacement, cause the screen cloth serious wear, screening efficiency is very low; The complete machine spatial volume is big, and install and use at the scene of being not easy to.The unit are disposal ability is low.Bring certain trouble for work such as on-the-spot production management, material transportation.In addition, the screen cloth of common electromagnetic vibrating screen is fixed, the easily stifled screening efficiency that also largely reduced of course of work sieve screen apertures.
Summary of the invention:
The object of the invention provides a kind of method and special-purpose electromagnetic vibrating screen with electromagnetic vibrating screen screening material, and install and use at the scene of can being convenient to, and improves screening efficiency and disposal ability, solves the problems referred to above that background technology exists.
The present invention seeks to realize by following technical scheme.
Method with electromagnetic vibrating screen screening material comprises the steps
1. material is by the top feed of screen cloth;
2. screen cloth the inclination angle scope between plane and the ground be set be ± 15 °;
3. screen cloth is movable, sieves in convey materials;
4. the screen cloth of electromagnetic vibrating screen coupling electromagnetic exciter carries out vibrosieve;
5. by electromagnetic exciting screening and screen movement screening material is filtered out oversize and screenings.
Screen cloth can be a horizontal positioned, the inclination angle scope can also be ± and 8 °, whole screen cloth is the ring-type screen cloth, external force drives the screen cloth shuttling movement, increases work efficiency.Said screen cloth can be common screen cloth, also can be the chain type screen cloth, can also be with materials such as rubber the metallic sieve more than two to be bonded together.With the sieve screen apertures of stopping up on the electromagnetic exciter cleaning one such trash screen.
The composition of electromagnetic vibrating screen comprises sieve nest, screen cloth, electromagnetic exciter, frame, and screen cloth is arranged in the sieve nest, and sieve nest is arranged on the frame, electromagnetic exciter and screen cloth coupling, its special feature be screen cloth inclination angle scope between plane and the ground be set be ± 15 °.
Screen cloth can and ground between the inclination angle be 0 °, horizontal positioned; Whole screen cloth is the ring-type screen cloth, is arranged on two volume net wheels, and volume net wheel is arranged on the frame, and external force drives the screen cloth wheel and rotates, and the screen cloth shuttling movement as known belt conveyor, sieves in convey materials, increases work efficiency.The circular flow of ring-type screen cloth is provided with the some electromagnetic exciters that mate with screen cloth in the screening workspace of screen cloth, carries out the exciting screening; Also be provided with the some electromagnetic exciters that mate with screen cloth in the non-screening workspace of screen cloth, screen cloth is carried out exciting cleaning, the sieve screen apertures that cleaning is stopped up; Screening work district is positioned at the top of volume net wheel, and non-screening work district is positioned at the below of volume net wheel.Because also be provided with the some electromagnetic exciters that mate with screen cloth in the non-screening workspace of screen cloth, the present invention has realized the automated cleaning to screen cloth, make the sieve screen apertures of sieving not have situation about stopping up, improve screening efficiency.
The screening feed can be on screen cloth any position, comprise two ends and middle part; The discharging of backwater side.
The present invention also is provided with known screen cloth tension mechanism and volume net wheel drive mechanism.
Adopt the present invention, because the inclination angle that screen cloth is arranged is less, the screen cloth shuttling movement, material is by screen cloth top feed, by the exciting screening of electromagnetic exciter and the motion screening acting in conjunction of screen cloth, finish screening work, can save equipment occupation space, reduce the compass screen surface wearing and tearing, improve screening efficiency, be convenient to the screen cloth cleaning, avoid stopping up sieve screen apertures, screen(ing) machine self has the function in cleaning one such trash screen hole, brings great convenience for field management, mass transport.
That the present invention has is rational in infrastructure, increase work efficiency, save the equipment occupation space characteristics.The present invention is applicable to various high-frequency electromagnetic vibration sieves, comprises common screen(ing) machine, revolution screen(ing) machine, stacked screen(ing) machine etc.
