In modern industrial production, whether it is coatings, paints, food slurries, traditional Chinese medicine extracts, or even chemical raw materials, many industries are facing the problems of separation, filtration, and classification of liquid and solid particles. Traditional static filtration or centrifugal separation methods often have pain points such as low efficiency, easy blockage, and inconvenient cleaning.Liquid vibrating screenIt is precisely the efficient and precise screening equipment designed to solve these problems.
1、 Working principle of liquid vibrating screen: combination of three-dimensional power and precision screening
The core working principle of liquid vibrating screen relies on a unique power system——Vertical vibration motorThe motor is equipped with unbalanced weights at both ends, which generate a comprehensive excitation force through its rotation, thereby driving the screening machine to perform complex three-dimensional movements.
1. Power source: vertical vibration motor
Structure:There are unbalanced weights with adjustable angles at both ends of the motor.
Motion generation:When the motor starts, the high-speed rotation of the upper and lower hammers generates centrifugal force. By adjusting the relative phase angle between two heavy hammers, the direction, magnitude, and proportion of the excitation force can be precisely controlled.
2. Core form of motion: Three dimensional rotational vibration
Horizontal and vertical synthesis:The motor design allows the excitation force to act simultaneously in both horizontal and vertical planes, forming a unique three-dimensional rotational vibration rather than a simple circle or linevibration.
Motion trajectory:The motion trajectory of materials on the screen surface presents a complex spiral forward trend, which can be decomposed into:
Vertical component:Generate upward ejection force on the material, increase the chance of fine particles passing through the sieve, and effectively prevent the sieve from clogging.
Horizontal component:Spiral diffusion of materials from the center of the screen surface to the surrounding areas, prolonging the residence time of materials and improving screening accuracy and efficiency.
3. Screening process
Feed:The liquid slurry to be processed is fed into the top inlet of the equipment and evenly falls into the center of the sieve.
Screening:Under the action of three-dimensional vibration, the slurry rapidly spreads out. Solid particles or droplets smaller than the sieve aperture quickly pass through the sieve under the action of gravity and vibration force, enter the lower sieve frame or are directly discharged.
Sorting out impurities:Impurities, clumps, or large particles larger than the sieve aperture are blocked by the sieve and move along the edge of the screen under vibration, ultimately being discharged from the top outlet to achieve solid-liquid separation or particle classification.
Summarize its work characteristics:Efficient anti blocking, high screening accuracy, large processing capacity, compact structure, and easy to clean and maintain.
