Ultrafine powder ultrasonic linear sieve

Abstract

The invention discloses an ultrafine powder ultrasonic linear sieve, which comprises a feeding plate, a linear sieve group, and a vibration support table, the linear sieve group is arranged on the upper surface of the vibration support table, and the feeding plate is arranged on the upper surface of the linear sieve group , the linear sieve group is composed of several layers of linear sieves, the planar shape and size of the feed plate, the linear sieve group, and the vibrating support table are the same, and the contact surfaces between the layers are fitted closely. The surface is bonded with a sealing strip. The screening system adopts a linear sieve structure, which better solves the problems existing in multi-layer screening and realizes the simultaneous separation of multiple products in a screening system; the vibration mode has the characteristics of high frequency and low amplitude, which makes the powder and metal sieve The friction of the mesh surface is small, which can better protect the powder surface; it adopts dual vibration motors and ultrasonic generators, and has multiple working modes to adjust the trajectory of the powder.

Description

technical field [0001] The invention belongs to the technical field of vibrating sieves, in particular to an ultrafine powder ultrasonic linear sieve. Background technique [0002] Ultrafine powder is widely used in today's process production. The powder produced by physical manufacturing methods needs to be sieved according to the particle size, usually by ultrasonic vibrating sieve. Ultrasonic vibrating screen is a device that vibrates the vibrating screen through an ultrasonic transducer, superimposed on the screen surface to form a high-frequency and low-amplitude ultrasonic vibration wave, when the ultrafine powder is close to the screen surface, it receives ultrasonic acceleration and improves the material The dispersibility when passing through the sieve keeps the material in a suspended state on the sieve surface, the particles larger than the sieve mesh are sieved to the discharge port, and the particles smaller than the sieve mesh fall through the mesh, especially ...

AI Technical Summary

Problems solved by technology

At present, ultrasonic circular vibrating sieves are commonly used in the screening of ultrafine powders, which make the powders move away from the center of the circle, and can only effectively separate the fine powders of 25 microns to 150 microns. The powders are easily damaged by collision and friction during screening, and due to the circular The type vibrating screen adopts an eccentric motor, and the equipment will have a tendency to swing left and right when in use, and it is impossible to superimpose multi-layer screens to achieve the purpose of screening powders of various particle sizes
