Problems solved by technology

[0009] Aiming at the problem that the existing waste magnetorheological fluid is difficult to recycle, and directly discarded causes environmental pollution and energy waste, the present invention provides a recycling and treatment method for waste magnetorheological fluid, which can recover unused magnetorheological fluid through centrifugation and electromagnetic adsorption. The magnetorheological fluid that has been preliminarily treated by any treatment agent is treated, and the main dispersed substance and carrier liquid are separated and recovered. The pure physical method is used for separation and recovery without introducing any new substances. The recovery efficiency of magnetic substances is high, and the recovered carrier liquid is slightly It can be used as a new carrier liquid after processing

Abstract

The invention discloses a recycling and treatment method of waste magneto-rheological liquid and belongs to the technical field of recycling and treatment of magnetic waste liquid. The method comprises the following steps: controlling a rotary speed of an inner barrel body to be 3600r / min-3650r / min; after running for 20min, electrifying a coil in an adsorption pipe to generate a magnetic field; controlling the intensity of the magnetic field to be 6.5T-6.7T, and keeping for 10min-12min; reducing the rotary speed of the inner barrel body to be 10r / min and keeping for 2min-3min; accelerating the inner barrel body to be 3800r / min-3850r / min; after stably running, adjusting the intensity of the magnetic field of the coil to be 7T-7.2T and keeping for 7min-9min; reducing the rotary speed of the inner barrel body to be 10r / min and keeping for 2min-3min; then adjusting the rotary speed of the inner barrel body to be 3900r / min-3920r / min; after stably running, adjusting the intensity of the magnetic field of the coil to be 8.3T-8.5T and keeping for 5min-6min; and reducing the rotary speed of the inner barrel body to be 10r / min and keeping for 2min-3min. The method utilizes a physical method to treat, a bonding effect of main dispersible particles and carrier liquid can be disconnected and the main dispersible particles and the carrier liquid are separated; new components are not introduced into the magneto-rheological liquid; and post-treatment is simple, the operation is simple and the separation rate is high.

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 method for recovery and treatment of waste magnetorheological fluid. 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 temperature application range, and not ea...
