Description
Technical field
The present invention relates to vibrosieve and conveying machinery equipment, particularly relate to a kind of novel mining vibrating screen of efficient energy-saving.
Background technology
Owing to be subjected to the limitation of traditional design theory, for a long time, in the employed inertia vibrating screen of Mineral Engineering, it is several to only limit to justify vibration shape track vibratory sieve, straight line vibration shape track vibratory sieve and general oval vibration shape track vibratory sieve etc., wherein:
Circle vibration shape track vibratory sieve, its " screen blinding " phenomenon that screen cloth (or sieve plate) is gone up critical particle has stronger " unfreezing " ability, makes the critical solid phase particles of blocking screen cloth or sieve plate eyelet tremble up or fall down.But the solid phase particles rebound on its compass screen surface seriously reaches excessive vibrating deflection and has reduced sediment transport chip removal speed.Simultaneously, the wearing and tearing to compass screen surface strengthen the service life of having reduced screen cloth or sieve plate.
Straight line vibration shape vibratory sieve sieves the sediment transport chip removal speed that can improve compass screen surface, the wearing and tearing that alleviate screen cloth or sieve plate than the circle vibration shape.But, owing to exist " dead band " of exciting force, sieve so maximum defective can not show a candle to the round vibration shape with regard to the ability that is " unfreezing " and alleviates " screen blinding ", " sticking screen ".Particularly be used for de-mediated work, if when liquid phase medium has certain viscosity, the linear pattern vibratory sieve more can not well adapt to.
General elliptical orbit vibration shape vibratory sieve also has the existing same defective of round vibration shape track vibratory sieve.
The balanced elliptic vibration shape track vibratory sieve that the present invention relates to, because it has the advantage that round vibration shape vibratory sieve and straight line vibration shape vibratory sieve are had concurrently, and round vibration shape vibratory sieve and the existing inherent shortcoming of straight line vibration shape vibratory sieve have been overcome, thereby, on " screen blinding " problem that effectively alleviates the last critical particle of screen cloth (or sieve plate) and " sticking screen " problem in the de-mediated process, has original advantage, thereby, be necessary to develop this novel balanced elliptic mining vibrating screen.
What the present invention relates to is elemental body, twin shaft (or multiaxis), motor synchronizing, balanced elliptic vibration shape track, inertia mining vibrating screen.
Summary of the invention
Technical problem to be solved by this invention is: a kind of novel elemental body, twin shaft (or multiaxis), motor synchronizing, balanced elliptic vibration shape track, inertia mining vibrating screen are provided, this vibratory sieve not only can overcome the disadvantage of existing inertia vibrating screen, has the advantage of efficient energy-saving simultaneously.
The technical solution adopted in the present invention is: mainly the base of vibrator, automatic control apparatus switch-box and the vibratory sieve of being made up of vibratory sieve screen box, two or four shock electric machines is formed.Wherein: the vibratory sieve screen box is bearing on the base by four unequal damping springs of spring rate.Vibrator is installed on the vibratory sieve screen box by bolster or connecting axle.Automatically the control apparatus switch-box is installed on the base.On the support of vibratory sieve screen box front end, the jack mechanism that adjusts vibratory sieve screen box inclination angle is installed.
The present invention compared with prior art has following major advantage:
(1) broken through the limitation of traditional design theory, designed a kind of have elemental body, twin shaft (or multiaxis), motor synchronizing, balanced elliptic vibration shape track, novel inertia mining vibrating screen, it belongs to domestic and international initiative in the mining vibrating screen product.
(2), realize switching electricity in turn automatically, when making motor be in " rest " state of outage in turn but do not influence the operate as normal of this vibratory sieve to motor owing to adopted the appliance switch box of built-in automatic control technology.Therefore energy-conservation, can save electric power 37%～58%.
(3) owing to adopted balanced elliptic vibration shape track, thereby have higher disposal ability, and extensively compare at present, can improve screening percentage 6%～10% at straight line vibration shape vibratory sieve with similar parameter to solid material.
The present invention also has advantages such as simple in structure, easily manufactured, with low cost except having above-mentioned advantage, be a kind of novel mining vibrating screen that is worthy to be popularized.
