Embodiment Construction
[0024] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited by the embodiments.
[0025] In the pulp mixing process in alumina production, the stripping pulp 2 is self-pressurized into the dilution tank 1, and the red mud washing liquid 5 sent by the delivery pump 6 and the aluminum hydroxide washing solution 8 sent by the delivery pump 9 are in the dilution tank 1. Effective mixing is carried out inside, and the mixed and diluted diluted slurry is transported to the red mud separation and washing process through the delivery pump 7.
[0026] Such as figure 1 Shown, the slurry mixing equipment in alumina production of the present invention, structure is as follows:
[0027] Replace the dilution tank with a dilution tank. A spiral ascending plate is installed in the dilution tank to slow down the flow rate of the secondary steam and effectivel...
