Defoaming device in wet-process phosphoric acid production

The utility model relates to the technical field of wet-process phosphoric acid defoaming, and discloses a defoaming device in wet-process phosphoric acid production, which comprises a defoaming box, a supporting bottom plate arranged at the bottom of the defoaming box, a feeding pipe and a discharging pipe which are respectively arranged at the top of the defoaming box, and a mixing defoaming mechanism, and the mixing defoaming mechanism comprises a servo motor mounted at the top of the outer wall of the defoaming box. According to the defoaming device in wet-process phosphoric acid production, under the action of the mixed spraying mechanism, when the rotating shaft rotates, the mixing rod is driven to rotate, and wet-process phosphoric acid materials continuously added into the defoaming box can be scattered and stirred according to the rotating action of the mixing rod, so that the wet-process phosphoric acid materials are fully scattered, and the defoaming effect is improved.
