Abstract
A multi-unit combined vibrating screen belonging to vibrating screening mechanical field, which is researched for solving the problems in damp and fine granules screening. The vibrating screen is composed of a plurality of independent vibrating screen units connected in sequence. Each vibrating screen unit is composed of independent screen box, screen surface, vibrator, motor transmission device and cushion device, etc. The obliquity of each screen surface of vibrating screen unit is arranged in decrease (increase) from feeding end to discharging end. As a result, the entire screen surface is in inferior fovea (protruding) shape. It has fulfilled the screening theory of combining multi-unit, multi-screen surface leaning angle, high and low frequency and large and small amplitudes and quick layering, lowed vibration weight and dynamic load of equipment, avoided resonance and facilitated macro-scale operation of equipment. Each unit screen box can realize beeline, round or elliptic motion. The vibrating screen can be applied for materials screening for each sector, in particular the screening of damp and fine granule material.
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 multi-unit combined vibration screen of the disposal ability and the screening efficiency of vibratory sieve.
Background technology
Present various vibratory sieve is gradually to maximizing and high efficiency direction develops, and problems such as the structure heaviness of thereupon bringing, difficult in maintenance, manufacturing cost height are also given prominence to gradually.The amplitude and the frequency ratio of a vibratory sieve are more single, the movement locus of material on compass screen surface is single, especially in the screening operation of moist fine granular materials (water content 7-14%, partition size 3mm-13mm), the material plug-hole, screening percentage is low, treating capacity is little etc., and problem can not get knot determines.Though segmental appendage sieve part has changed the kind of drive of its structure and compass screen surface, has increased the sieve plate rib in the both sides of compass screen surface, it is heavy that whole screen box seems equally, safeguards also very inconveniently, do not satisfy the requirement of difficult screened material classification.
The utility model content
The utility model provides a kind of multi-unit combined vibration screen, can carry out classification to moist fine granular materials effectively, improves the disposal ability and the screening efficiency of vibratory sieve.
The utility model is realized by following measure.Multi-unit combined vibration screen is made up of screen box, compass screen surface, vibrator, transmission gear for electric motor, vibration damping holder device etc., it is characterized in that: complete machine oscillation sieve by 2-10 independently the vibratory sieve unit link together and form, each vibratory sieve unit is by compositions such as screen box, compass screen surface, vibrator, transmission gear for electric motor and vibration absorber independently; Whole compass screen surface is by the compass screen surface of each vibratory sieve unit head and the tail overlap joint successively, and the screen angle of each vibratory sieve unit (angle of compass screen surface and horizontal plane) is-10-36 °; For preventing the material spilling of compass screen surface junction, the discharge end transition portion of a last vibratory sieve unit screen box places in the feeding end of next vibratory sieve unit screen box.
For adapting to the needs of different material sieving technology, vibratory sieve also has following feature: the mode that the inclination angle of each vibratory sieve unit compass screen surface tapers off from the feeding end to the discharge end is arranged, and makes whole compass screen surface be spill down; Or the inclination angle of each vibratory sieve unit compass screen surface is the mode that increases progressively and arranges from the feeding end to the discharge end, makes whole compass screen surface present convex; Or the inclination angle of each vibratory sieve unit compass screen surface is identical, makes whole compass screen surface be planar shaped.The compass screen surface of each vibratory sieve unit is the arc that raises up.Simultaneously the amplitude of each vibratory sieve unit and frequency are by the high-frequency of feeding end, little magnitude transition low frequency, the large amplitude to discharge end; Or the amplitude of each vibratory sieve unit and frequency are by the low frequency of feeding end, the high-frequency that large amplitude carries out the transition to discharge end, little amplitude; Or frequency, the amplitude of each vibratory sieve unit equates from the feeding end to the discharge end.According to the needs of screening material, the eccentric mass direction of rotation of each vibratory sieve unit vibrator can be the feeding flow path direction or predicts flow path direction.The number of plies of compass screen surface can be the 1-3 layer.
Whole compass screen surface is from the feeding end to the discharge end, and material is in operation, and on the vibratory sieve unit compass screen surface different movement velocity and different impelling intensity is taking place separately, and speed from fast to slow or from slow to fast helps the layering of material, saturating sieve.Such mechanism effectively reduces the intergranular coefficient of friction of accumulation material at screen(ing) machine feeding end place, destroy the cohesive force between viscosity bulk material body granules, reduces adhesion between viscous material and screen cloth, is convenient to loose, the saturating sieve of material.On other vibratory sieve unit compass screen surface, make the material after the loose layering be fluidized state, strengthen the acceleration of gravity of the saturating sieve of material particles, the very fast sedimentation of small particles material contact with compass screen surface and sieve thoroughly fast, reach desirable screening effect.
The utility model has the advantages that, because the compass screen surface that adopts 2-10 section different angle sieve nest compass screen surface to form, the operation principle that height frequency, big or small amplitude combine makes the material on the vibratory sieve compass screen surface, particularly viscosity bulk material loose rapidly, spread out, the size particles layering is obvious, thickness is even, the non-blocking screen hole, and saturating sieve is thoroughly, it is big to have treating capacity, the characteristics that screening efficiency is high.Realized that multiple-unit body, many screen angles, height frequency, big or small amplitude combine, the screening theory of rapid layering; The ginseng that the has reduced equipment weight of shaking has reduced the dynamic load of equipment, has avoided the generation of resonance, is convenient to the large scale development of equipment, has broad prospects and practicality widely.Each unit screen box can be realized straight line, circle or elliptical trajectory, is applied to the screening operation of every profession and trade material, is particularly suitable for the screening operation of moist fine granular materials (water content 7-14%, partition size 3mm-13mm).
