Abstract

The invention discloses a magnetorheological fluid recovery device and a treatment method based on ionization and centrifugation, and belongs to the technical field of magnetic waste liquid recovery and treatment. The device includes an outer barrel, an inner barrel, an adsorption tube, and a filter screen. The inner barrel is rotatably mounted in the outer barrel through a bearing and driven by a motor. The sidewall of the inner barrel is provided with filter holes that communicate with the inside and the outside, and the adsorption tube is arranged in the inner barrel. In the middle of the body, a coil is arranged in the adsorption tube, an electrode plate is arranged in the inner barrel, a filter screen is arranged on the inner side wall of the inner barrel and covers the filter hole, and a recovery stop valve is arranged on the outer wall of the outer barrel. The method of the invention realizes the separation and recovery treatment of the magnetorheological fluid through ionization treatment, centrifugal breaking treatment and centrifugal separation treatment. The present invention processes the magnetorheological fluid, separates and recovers the main dispersed particles and the carrier liquid, does not need any treatment agent for preliminary treatment in the early stage, and has high recovery efficiency, and the recovered carrier liquid can be used as a new carrier liquid after a little treatment.

Description

technical field [0001] The invention belongs to the technical field of recovery and treatment of magnetic waste liquid, and more specifically relates to a magnetorheological fluid recovery device and treatment method based on ionization and centrifugation. Background technique [0002] Magnetorheological Fluid (MR fluid for short) is a controllable fluid, which is an emerging intelligent material. It is mainly composed of magnetic particles, carrier liquid and stabilizer. Suspension liquids with characteristic non-colloidal properties. Magnetorheological fluid can produce obvious magnetorheological effect under a magnetic field, and can realize rapid and reversible conversion between liquid and solid or semi-solid. During this process, the viscosity of magnetorheological fluid keeps changing continuously, and the entire conversion process is extremely fast. And controllable, has the characteristics of extremely small energy consumption, convenient preparation, wide temperat...
