Abstract
The utility model relates to a solid separating plant for industry, in particular to an electromagnetic vibrating screen, which technical scheme is that: the utility model comprises a screen body (1), a screen mesh (6), a plurality of electromagnetic vibration excitors (2) and a frame (7). The screen mesh (6) is positioned inside the screen body (1), and the screen body (1) is positioned on the frame (7); the electromagnetic vibration excitor (2) is matched with the screen mesh (6); the angle between the screen mesh (6) positioning plane and the ground is ranged in plus or minus 15 degree. By completing the screening by utilizing the vibrating screening of the electromagnetic vibration excitor and the moveable screen mesh, the utility model can save the space occupy of the equipment, lower the screen abrasion and improve the screen efficiency, which therefore is convenient for cleaning the screen mesh and prevents the screen mesh form block as well as greatly facilitates the field management and the materials transmission. The utility model is characterized by reasonable structure, improved working efficiency and saved equipment space occupy, which is suitable for various electromagnetic vibration screen meshes with high frequency comprising general screening machine, revolving screening machine and cascade screening machine, etc.
Description
Technical field:
The utility model relates to a kind of solid separation screening equipment, particularly electromagnetic vibrating screen of industrial use.
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, and 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 utility model purpose provides a kind of electromagnetic vibrating screen, and install and use at the scene of being convenient to, and improves screening efficiency and disposal ability, solves the problems referred to above that background technology exists.
Technical solutions of the utility model are: electromagnetic vibrating screen is formed and is comprised sieve nest, screen cloth, electromagnetic exciter, frame, screen cloth is arranged in the sieve nest, 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 be a horizontal positioned, the inclination angle scope can also be ± 8 °, whole screen cloth is the ring-type screen cloth, be arranged on two volume net wheels, volume net wheel is arranged on the frame, and external force drives the screen cloth wheel and rotates, the screen cloth shuttling movement, as known belt conveyor, in convey materials, sieve, increase 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 utility model also is provided with known screen cloth tension mechanism and volume net wheel drive mechanism.
Adopt the utility model, 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.
The utlity model has rational in infrastructure, increase work efficiency, save the equipment occupation space characteristics.The utility model is applicable to various high-frequency electromagnetic vibration sieves, comprises common screen(ing) machine, revolution screen(ing) machine, stacked screen(ing) machine etc.
Description of drawings:
Accompanying drawing is a user mode structural representation among the utility model embodiment.
Among the figure: sieve nest 1, electromagnetic exciter 2, electromagnetic exciting arm 3, volume net wheel 4, volume net wheel 5, screen cloth 6, frame 7, frame resiliency supported 8, volume net actuation 9.
The specific embodiment:
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
In an embodiment, the utility model is formed and is comprised sieve nest 1, screen cloth 6, some electromagnetic exciters 2, frame 7, screen cloth 6 is arranged in the sieve nest 1, sieve nest 1 is arranged on the frame 7, be provided with frame resiliency supported 8 below the frame, electromagnetic exciter 2 mates by electromagnetic exciting arm 3 with screen cloth 6, and the inclination angle between screen plane and the ground is 0 °, setting just parallel to the ground, horizontally disposed.Whole screen cloth is the ring-type screen cloth, is arranged on two volume net wheels 4,5, and volume net wheel is arranged on the frame 7, known volume net actuation 9 drives the screen cloth wheel and rotates, and the screen cloth shuttling movement is as known belt conveyor, in convey materials, sieve, increase work efficiency.Material is dropped on the screen cloth of motion by screen cloth top feed, by the exciting screening of electromagnetic exciter and the motion screening acting in conjunction of screen cloth, finishes screening work.
