Problems solved by technology

[0009] Aiming at the problem that the existing discarded magnetorheological fluid is difficult to recycle, and directly discarded causes environmental pollution and energy waste, the present invention provides a magnetorheological fluid recovery device and treatment method based on temperature change, ionization and centrifugal action, The magnetorheological fluid can be recovered through temperature change and centrifugation, and the main dispersed particles and carrier liquid can be separated and recovered. There is no need for any treatment agent for preliminary treatment in the early stage, and the recovery efficiency of magnetic substances is high. At the same time, no new substances are introduced in the treatment. , 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 temperature change, ionization and centrifugal action. 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 pr...
