Description

High frequency vibration dewatering screen in order to adapt slime recovery and fine material dehydration classification and processing a large quantity, good dewatering effect, strong adaptability, the high frequency and high vibration strength and mechanical properties.

According to the needs of the mechanical structure and process parameters, vibrator is arranged on the screen at the top of the box center of gravity. This arrangement the sieve in the feeding end is elliptical, central to the circular trajectory, discharging end is elliptic, elliptic a circular elliptical motion.

Small contact as soon as possible with the long axis of the elliptical motion because of the unique characteristics of the screen the enemies into the feed end of the sieve and the angle between a sharp angle, end to the major axis of the ellipse and the screen plane angle is an obtuse angle. This makes the material in the feeding side movement speed is greater than the discharge end of the moving speed, to ensure the material in the sieve and the feeding end soon loose so material layer is thin, so that the fine material layered sieve and sieve through water dry membrane rupture dehydration; and a discharge end of the speed of material, can extend the material in the sieve surface dehydration time and improve the effect of dehydration. Screening machine has the characteristics, strengthen the dehydration effect.

Effect of the frequency of the use of folding and editing on the dewatering efficiency

The frequency of high frequency vibrating screen can be adjusted through the test of the effect of different frequency on the screening index, the results show that: when the frequency is *3.*3Hz, the amplitude is 1.*2mm, the best index of the screen is the best choice.

Effect of feed concentration and particle size on the moisture content of the product

Moisture in the product size and check in concentration and particle size have close relationship, high frequency vibrating screen. Processing roughly the same amount, feeding low concentration, high moisture products; feed concentration is high, low moisture products; size grading, low moisture products; particle size of feed hours, aquatic products high
