High frequency vibration vortex sieve for domestic initiative, is a new, efficient, energy-saving coal washing equipment. 
 Uses and characteristics: 
 Vortex sieve high frequency vibration and the end of the main coal preparation plant to the coarse slurry before dehydration, mud, slime and other rough classification can also be used for other materials similar to dehydration, mud, grading purposes. 
 The device is a new high off mud, dehydration, grading the energy-saving equipment, with a drive power is small, no moving parts, no lubrication, equipment, light weight, large capacity per unit area of screen, when running without a fixed political parties personnel to operate, can achieve automatic control, noise and so on. 
 Works; 
 With constant pressure tank or pump the material into solid and liquid mixed swirl nozzle 1 screen, the nozzle into the guide slot along the tangent direction 2, in the centrifugal force, friction and material under the action of gravity, the linear motion into a downward spiral , the guide groove 2 into 3 conical sieve, the material in the course of the campaign to achieve solid-liquid separation, sieve through the sieve material sewn together with liquid 8 through the filtrate exit discharge, dehydration cone of solid materials are solid materials, the lower screen export 10 discharge.
