Abstract

The invention discloses a magnetic powder vacuum mixer. The mixer comprises a frame, a mixing device, a hydraulic driving device, a condensation recovering device, a heating device and an electric controlling device. The mixing device comprises a material chamber, a lifting platform, a main motor, a transmission shaft, a stirring mechanism, a material chamber cap and a discharging port. The hydraulic driving device comprises a hydraulic oil pump, a sliding plate, a horizontal hydraulic cylinder, a slideway, a sliding sleeve and a lifting hydraulic cylinder. The condensation recovering device comprises a condensing machine set, a vacuum pump, a vacuum valve, a recovering tank and pipelines. The heating device comprises a heater, a heat circulating pump and a heat conducting water pipe. Theelectric controlling device comprises an electric controlling box and a frequency converter. The material chamber cap is provided with a gas discharging valve, two through holes and a camera hole. A display screen is arranged on one side of the lifting platform. With the mixer provided by the invention, magnetic powder can be prevented from being oxidized during a mixing procedure, the cost of nitrogen protection can be saved, and the product quality can be ensured. With the condensation recovering device, acetone can be recovered and reused, such that the production cost is saved, and the production process is green and environment-friendly.

Description

technical field [0001] The invention relates to a material mixing device used in a bonded magnet compression molding process, in particular to a magnetic powder vacuum mixing agitator. Background technique [0002] As a special equipment for bonded NdFeB permanent magnets, the magnetic powder mixing mixer is applied to the mixing procedure in the bonded magnet compression molding process. The traditional magnetic powder mixing mixer is to mix the raw material rare earth permanent magnet powder and epoxy resin binder under the protection of nitrogen, which has the following defects: 1. During mass production, the quality of the product will vary; 2. In order to To prevent the rare earth permanent magnet powder from being oxidized during the stirring process, it is necessary to use nitrogen protection, which is expensive and increases the production cost; 3. During the mixing process, a large amount of acetone gas volatilized by acetone as a solvent cannot be effectively recov...
