Background technology
Linear vibrating screen is coal preparation plant's capital equipment, linear vibrating screen produces vibration by harmonic excitation power, this harmonic excitation power and horizontal direction be (homemade linear vibrating screen adopts 40 ° ~ 45 °) at an angle, order about the screening material and make continuous oblique upper paraboloiding movement at compass screen surface, material is loose when throwing, collision is sieved granule thoroughly when meeting with compass screen surface, thereby realizes classification, dehydration, de-mediated, the desliming of material.The quality of linear vibrating screen screening effect directly has influence on the effect of equipment thereafter, and the quality of final products has been played important effect.Therefore the efficient that how to improve classification, dehydration, desliming and the de-mediated of linear vibrating screen is the problem that people pay close attention to always.
Under certain pan feeding condition, the factor that influences the efficient of its classification, dehydration, desliming and de-mediated is mainly:
(1) increases oscillation intensity and improve amplitude, but the structural strength of screen(ing) machine is proposed bigger requirement;
(2) increase vibrating direction angle, but reduced the speed of service of material, reduced treating capacity;
(3) according to the vibration characteristics of screening material, change the structure of compass screen surface.
From these three kinds of approach, improving the straight-line oscillation screen capacity by the above two has certain limitation, and improving the straight-line oscillation screen capacity by the structure that changes compass screen surface then may have bigger enforcement space.According to the synthetic and decomposition principle of power, the linear vibrating screen harmonic excitation is advocated and will be made up of two parts component, the component on the horizontal direction and the component on the vertical direction.Because the compass screen surface of linear vibrating screen generally is horizontal structure at present, when the oblique upper paraboloiding movement of material sieves thoroughly, component on the horizontal direction orders about the screening material toward the discharge end motion, and is not used to the sieve effect, has only the component on the vertical direction to play the sieve effect.If therefore to the innovation by the compass screen surface structure, the component of horizontal direction also can be fully used, play the sieve effect, will improve the screening efficiency of linear vibrating screen effectively.
Summary of the invention
