Abstract
The utility model discloses a new-style screen surface of a linear vibration screen, which is used for the size grading of materials. A screen bar adopts the reasonable shapes of geometric bodies; the screen bar is arranged in a reasonable way to form the new open section of screen openings; a screening surface is changed into the wave type form the smooth type; the screen openings bear the exciting force in a vertical or approximate vertical way; the material particles can not block up and generate the minimum abrasion to the screen surface when entering in the screen surface. The utility model can extend the service period of the screening surface, reduce the cost, improve the working quality and the screening efficiency and increase the processing ability. The utility model can be spread to use in the enterprises of metallurgy, mines, chemical industry, manufacture of building materials, coal wash, dreg removal, etc.
Description
The utility model belongs to a kind of improvement that industrial and mineral is made the linear vibrating screen sieve nest structure of material gradation or slagging-off usefulness, specially refers to the improvement to horizontal and elevation angle formula linear vibrating screen compass screen surface.
Widely used linear vibrating screen in the present industrial and mining enterprises, because its critical piece compass screen surface is unreasonable on design and structural configuration, produce in the motion process that material particles is worked under level and elevation angle state and glide, cause the wearing and tearing of material to compass screen surface, not only cause the compass screen surface life cycle short, reduce operating efficiency, increase cost, but also, influence the classification of material particles and reduce work quality because of the wearing and tearing of the sieve aperture of compass screen surface.In addition, also because of the sieve aperture aperture arrangement is unreasonable, the downslide of material particles in addition causes the sieve pore blockade of compass screen surface, and influence is produced.
Yet, special construction of the present utility model is arranged and has successfully been solved the problems referred to above, both former compass screen surface was improved, adopt rational sieve aperture open section, and improved grating its geometry shape of forming compass screen surface, rearrange simultaneously, change compass screen surface into wave by traditional level and smooth shape, sieve aperture is vertically born or near normal is born exciting force.Finally make the irrational wearing and tearing of sieve aperture and clogging significantly reduces or eliminate substantially.
The novel compass screen surface that the purpose of this utility model is to provide that a kind of cost is low, the life-span long, work quality and classification efficiency and disposal ability all improve greatly.
The utility model is achieved in that a kind of novel linear sieve of design compass screen surface, by a plurality of sections is that trapezoidal grating is formed according to equidistant arrangement, the sieve aperture of compass screen surface changes awave open section into by traditional level and smooth shape, make the vertical or near normal of sieve aperture bear exciting force, unlikely obstruction and to compass screen surface generation minimal wear when making material particles enter compass screen surface.
Advantage of the present utility model and good effect be: overcome downslide that linear vibrating screen promotes to produce when material moves upward at exciting force and caused to the wearing and tearing of compass screen surface with to the obstruction of sieve aperture.Can prolong the life cycle of compass screen surface, reduce cost, improve work quality and screening efficiency, increase disposal ability.
Be described further below in conjunction with accompanying drawing:
Accompanying drawing 1 is the schematic diagram of linear vibrating screen, and among the figure: 1 is compass screen surface, and 2 is screen frame, and 3 is shock-absorbing spring, and 4 is bearing, and 5 is charging aperture, and 6 for discharging opening α is the exciting angle, and F is an exciting force.
Accompanying drawing 2 is sectional drawings of former compass screen surface.
Accompanying drawing 3 is sectional drawings of the present utility model, among the figure, and α
1Be the exciting angle, and α
1=90 ° or α
190 ° of ≈, F
1Be exciting force.
In the accompanying drawing 1: compass screen surface 1 is installed in the screen frame 2, and screen frame 2 is seated on the bearing 4 by the connection of shock-absorbing spring 3.Wherein, the two ends of screen frame 2 are respectively equipped with charging aperture 5 and discharge gate 6, and charging aperture 5 is lower than discharge gate 6.During work, material feeds compass screen surface 1 by charging aperture 5, under the vibration of shock-absorbing spring 3, material particles is owing to upspring by the effect of exciting force to leave forward, wherein thin rank particle spills along sieve aperture and enters next procedure, thick rank particle continues to be dished out forward and returns last process through discharging opening 6 and continued processing and handle, and goes round and begins again.
The utility model is applicable to the enterprise of usage level formulas such as metallurgy, mine, chemical industry, building materials, coal washing or elevation angle formula linear vibrating screen, is specially adapted to technologies such as ore dressing, coal washing and slagging-off.
