The main component of vibrating screen equipment


Vibrating screen using the motor or electric or natural vibration source driving outside the ordinary motor drag, material do the direction along a straight line on the surface of the screen as a parabola, the screen body along the direction of vibration force do periodic reciprocating vibration, material under the movement by screening, achieve the aim of screening materials.Vibrating screen is mainly composed of sieve body, vibrator, elastic component and other components.
1, the screen body
Such as transport tank, screen box, mesa and balance the body, etc., but in some vibrating screen extension no balance in the body.In order to complete a variety of processes, they usually do periodic motion.The screen box as the main support of vibrating screen, its stress and load conditions will directly affect the life of the vibrating screen, so the force of the screen box should be given special attention, we can make use of the finite element software understanding of the specific load analysis of screen box, thus can be targeted to the screen box structure make improvements, for the part of the need to strengthen to strengthen.
2, vibrator,
Used to produce cycle vibration force, make the work the body produces a continuous vibration.Commonly used vibrator have inertia vibrator, elastic connecting rod type vibrator, electromagnetic vibrator, hydraulic or pneumatic vibrator, and CAM type vibrator, etc.For inertia vibrating screen, and it USES is inertia vibrator.Inertia vibrator set one eccentric block, mainly by the eccentric block rotary motion generated by the eccentric force to achieve the purpose of the vibration.
3, elastic element
Including vibration isolation spring (its role is to support the body vibration, to make the body to achieve the required vibration, and reduce the dynamic load to the foundation or structure frame), the main vibration spring (that is, the resonance spring or spring energy storage) and connecting rod spring (deliver exciting force, etc.).In the practical application, often spring set is used to realize vibration or vibration isolation.This is because the spring is also a kind of standard parts, the specification is relatively fixed, for certain specific numerical requirements of spring, we only by a few spring cooperate to meet these conditions.
