Abstract
The utility model relates to an amplitude increasing ellipse banana screen, belonging to the machinery field of a vibrating screening; aiming at the disadvantages of the existing banana-shaped linear vibrating screen, for example, when the linear vibrating screen is used for material size grading operation (in particular to the grading operation of more materiel particle content on the screen), a single linear motion trial is generated on a screen surface, thereby causing slow material moving speed at the discharge end on the screen and leading material layers to be accumulated; a throwing <dead area> exists, so as to lead the material on the screen surface to form blocking holes, screening percent is low, and the handling capacity is small, and the like, the amplitude increasing ellipse banana screen is designed. The utility model provides an amplitude increasing ellipse banana screen, and the key technology of the screen is that: the ellipse motion trial is arranged on the screening surface on each section, and the discharge end with small leaning angle of the screening surface has high amplitude, and the feeding end with large leaning angle of the screening surface has low amplitude, thereby leading the material to not be accumulated on the screening surface of the discharge end and to not be blocked, in addition, the screening rate is high and the handling capacity is large. The amplitude increasing ellipse banana screen can be widely applied to the material size grading operation in all the industries.
Description
Technical field:
The utility model belongs to the vibration screening machinery field, mainly relates to the screening operation of every profession and trade material, can effectively improve the oval banana screen of amplitude progressively increase type of the disposal ability and the screening efficiency of vibratory sieve.
Background technology:
The banana-shaped linear vibrating screen of present utilization, what adopt is straight-line trajectory, screen angle is the arcs of recesses layout that tapers off from the feeding end to the discharge end, when being used in the raw meal particle size graded operation (the particularly more graded operation of oversize material granule content), produce single straight-line trajectory on its compass screen surface, material translational speed on compass screen surface is along with successively decreasing of screen angle from fast to slow, make material at discharge end compass screen surface section bed of material progressive additive, the formation wedge shape is piled up, cause screening efficiency sharply to descend, treating capacity reduces thereupon.The screen(ing) machine of straight-line trajectory in addition, the impelling direction of material is unique, there is throwing " dead band " in critical particle and hole clipping makes the material group on the whole compass screen surface easily form plug-hole in the vibrating deflection direction in the material.
The utility model content:
The utility model provides a kind of amplitude progressively increase type oval banana screen, material is when overall concave arc compass screen surface top sieve componental movement, change less before and after the translational speed, thickness of feed layer is even, the size particles layering is obvious, and critical particle is difficult for hole clipping, and compass screen surface remains great percent opening, make its screening efficiency height, treating capacity is big.
The utility model realizes that by following measure the body vibration sieve is made up of screen frame, compass screen surface, vibrator, transmission gear for electric motor, vibration damping holder device.Its vibrator is two-axis, transmission between the diaxon is adopted is the motor synchronizing structure or forces synchronization structure, the vertical line and the horizontal plane angle α of line are 40-60 ° between corresponding two axle center, eccentric weight near corresponding eccentric block on the compass screen surface discharge end vibrator shaft is greater than the eccentric weight that another goes up corresponding eccentric block, makes the diaxon switched in opposite during work.The utility model principal character is: the eccentric mass on the corresponding diaxon of vibrator is unequal; Be elliptical trajectory on each section compass screen surface; The discharge end amplitude that screen angle is little is big, and the big feeding end amplitude little (being that amplitude is to progressively increase along with successively decreasing of each section screen angle) of screen angle.Also can be according to characteristics that are sized material and requirement, regulate the major axis and the minor axis amplitude of elliptical orbit: the major axis value of its elliptical orbit is by eccentric mass on the vibrator diaxon and decision; The minor axis value is determined by the eccentric mass difference on the vibrator diaxon.The number of plies of compass screen surface can be by the technological requirement that is sized operation by the selection design of one deck to multilayer.
The utility model has the advantages that, material is elliptical trajectory on overall concave arc compass screen surface, promptly roll and climb the operation of jump state, and the stroke (amplitude) that jumps is to increase gradually along with reducing of screen angle, these characteristics, compensated the weak point of banana screen in the past, can be widely used in the grading operation of every profession and trade material, particularly the more graded operation of oversize material granule content.
Description of drawings:
Accompanying drawing 1 and Fig. 2 are structural representation of the present utility model, and promptly the oval banana screen of amplitude progressively increase type is assemblied by screen frame 1, vibrator 3, compass screen surface 5, vibration damping holder device 6, transmission gear for electric motor 7.Vibrator 3 is two-axis, transmission between the diaxon is adopted is the motor synchronizing structure or forces synchronization structure, eccentric block 2 on it is assemblied near on the discharge end axle, eccentric block 4 is assemblied near on the feeding end axle, the eccentric weight of eccentric block 2 is greater than the eccentric weight of eccentric block 4, produce the elliptical orbit that varies in size when can make screen(ing) machine work by adjusting, on the vibrator 3 between the corresponding axle center of diaxon the vertical line and the horizontal plane angle α of line be 40-60 °.Fig. 2 be the A of Fig. 1 to view, expression be that the layout of transmission gear for electric motor 7 and vibrator 3 is connected and drive connection, make eccentric block 2 and eccentric block 4 switched in opposite during work.
The specific embodiment:
In conjunction with the accompanying drawings 1 and Fig. 2 one of them embodiment of the present utility model is described: the oval banana screen YXF3073/6 of a kind of amplitude progressively increase type is assemblied by screen frame 1, vibrator 3, compass screen surface 5, vibration damping holder device 6, transmission gear for electric motor 7.Its vibrator 3 is two-axis, what the transmission between the diaxon was adopted is the motor synchronizing structure, promptly drive simultaneously with two identical motors of specification, and reverse rotation, make eccentric block 2 and eccentric block 4 on 3 of the vibrators also produce backward rotation, the vertical line and the horizontal plane angle α of line are 45 ° between corresponding two axle center of two axles on the vibrator 3, and the eccentric mass of corresponding eccentric block 2 is 121kg on the close compass screen surface discharge end axle, and another eccentric mass of going up eccentric block 4 is 92kg.The utility model principal character is: be elliptical trajectory on each section compass screen surface; The discharge end amplitude that screen angle is little is big, and the big feeding end amplitude little (being that amplitude is to progressively increase along with successively decreasing of each section screen angle) of screen angle.The oval banana screen of YXF3073/6 type amplitude progressively increase type, the compass screen surface design is one deck, and mass of vibration is 17000kg, and the same motor that is 30KW with two power drives, and the elliptical orbit major axis that the screen(ing) machine feeding end is produced is 9mm; Minor axis is 3mm, and the elliptical orbit major axis that the screen(ing) machine discharge end is produced is 11mm; Minor axis is 5mm.When this screen(ing) machine was used in the grading operation of iron ore, sieve aperture was 10 * 25mm, and screening efficiency reaches 87%, and treating capacity reaches 800-850t/h.
