Abstract

The invention discloses a device and a treatment method for recovering and treating magnetorheological fluid, belonging to the field of recovery and treatment of magnetic waste fluid. The device includes an outer barrel and a pressurized filter device. A filter screen is provided at the bottom of the pressurized filter device, and a cooling duct is provided on the filter screen; an adsorption tube is provided above the filter screen, and a coil is provided in the adsorption tube; an electrode is provided above the adsorption tube. plate, the bottom wall of the pressurized filter device is provided with several filter holes, and its side wall is provided with an upper vent pipe, a lower vent pipe and several groups of heating resistors; the side wall of the outer barrel is provided with a recovery shut-off valve . The invention combines temperature change treatment, high-pressure filtration and breaking treatment, and ionization to treat waste magnetorheological fluid without adding chemical treatment agents in the early stage, which will not cause secondary pollution to the carrier liquid and increase the cost of subsequent treatment, and improves Efficiency, saving processing cost, the best separation effect of magnetorheological fluid can reach 99.9%.

Description

technical field [0001] The invention belongs to the field of recovery and treatment of magnetic waste liquid, and more specifically relates to a device and a treatment method for recovery and treatment of magnetorheological fluid. Background technique [0002] Magneto-rheological polishing is a technology that uses the rheology of magnetorheological polishing fluid in a magnetic field to locally modify and polish the workpiece. Magnetorheological fluid is composed of carrier liquid (such as water, silicone oil, etc.), discrete polarizable micron-sized magnetic sensitive particles, surfactants, polishing particles and additives with other functions. The magnetorheological fluid is circulated by the polishing disc into the polishing area with a small distance formed between the workpiece and the polishing disc. In this area, the magnetorheological fluid undergoes a rheological effect under the action of a high-gradient magnetic field to become hard, As the viscosity increases...
