Multi-degree-of-freedom control electric magnetic suspension screen

Abstract

The invention provides a multi-degree-of-freedom control electric magnetic suspension screen. The electric magnetic suspension screen comprises an outer box body, a box body upper cover, a screen box,a screen cover, an electromagnetic coil system and a control system, wherein the screen box is arranged in the outer box body; the electromagnetic coil system comprises a plurality of electromagneticcoil devices, and is divided into four electromagnetic coil device sets which are correspondingly arranged on the side wall of the screen box, the inner side wall of the outer box body, the outer side wall of the screen cover and the inner side wall of the box body upper cover; and the control system is electrically connected to a micro-current controller in each electromagnetic coil device, andis used for controlling the current in a coil of each electromagnet, so that the screen box linearly moves forwards and backwards, leftwards and rightwards, and upwards and downwards, or swings forwards and backwards, and leftwards and rightwards or self rotates. According to the electric magnetic suspension screen, the screen box is suspended in the outer box body through the electromagnetic coilsystem and can move in the outer box body, so that the automatic screening of the chemical material powder is realized, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of material screening, in particular to an electromagnetic levitation screen controlled by multiple degrees of freedom. Background technique [0002] In chemical experiments, the size and quality of chemical material powders directly affect the success or failure of chemical experiment results, and most of the purchased chemical material powders have problems such as excessive particle size, poor uniformity, and impurities. Material powder is screened. At present, experimenters mainly use ordinary sieve boxes to manually screen. A device for automatic screening. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an electromagnetic suspension sieve controlled by multiple degrees of freedom, which realizes automatic screening of chemical powders and improves screening efficiency. [0004] The present invention achieves the above-mentioned technical purpose ...
