Stirring and mixing device for acidolysis solution and flocculant

The utility model discloses a stirring and mixing device for acidolysis solution and flocculant, and belongs to the technical field of titanium white production by sulfuric acid process. The structure of the stirring and mixing device for the acidolysis solution and the flocculant comprises a buffer tank, a mixing tank and a subsider, one side of the top of the mixing tack is communicated with the buffer tank through a pipeline, the other side of the top of the mixing tack is communicated with a flocculant storage tank through another pipeline, the upper portion of the mixing tank is communicated with the subsider through a overflow pipe, a blender is arranged in the mixing tank, a discharging pipe is arranged on the side of the inside of the mixing tank, the bottom end of the discharging pipe is located at the lower portion of the inner cavity of the mixing tank, the top end of the discharging pipe is communicated with an empty pipe, and the upper portion of the discharging pipe is communicated with the overflow pipe. According to the stirring and mixing device for the acidolysis solution and the flocculant, enough stirring time (6-8 min) for mixing the flocculant and the acidolysis solution evenly is guaranteed; foam formed in the flocculant stirring process can be eliminated, so that it is guaranteed that no foam exists in the flocculant and the acidolysis solution when the flocculant and the acidolysis solution enter a settling basin, and the settling quality is improved; the mixing tank can not be blocked, and the stability and continuity of the operation are guaranteed.
