[0002] In order to increase the amount of clean coal collected in coal mines, distilled water magnetization flotation pulp is usually used. Distilled water magnetization flotation can improve the flotation effect of clean coal. At present, a magnetization device is usually used to magnetize the pulp to reduce the possibility of impurities in the pulp. Floatability, improve the buoyancy of clean coal, but the magnetization device currently used has the following defects: 1. The time for the ore body to undergo dissolved oxygen metamorphism in distilled water should not be too long, too long will lead to the output of medium metamorphic coal, medium The output of metamorphic coal will be affected by dissolved oxygen oxidation, and the current magnetized pulp is not only affected by dissolved oxygen oxidation in distilled water during flotation, but also oxidized by outside air, thereby reducing the output of medium metamorphic coal. 2. Ore pulp The particles are relatively large, and during the flotation process, the magnetized distilled water cannot fully contact the pulp, thereby reducing the magnetization effect of the pulp. Some magnetized flotation devices usually use dynamic stirring blades for stirring, and the structure of this stirring method is relatively complicated. 3. Magnetization The device usually uses a large amount of distilled water for pulp flotation, and the distilled water becomes dirty water after use. Usually, it is discharged and treated, which will cause a large amount of waste of water resources. Therefore, the present invention provides a flotation pulp magnetization machine
