Preparation device for TPA (terephthalic acid) slurry

The utility model relates to a preparation device for TPA (terephthalic acid) slurry, which belongs to the technical field of production equipment for chemical raw materials. The preparation device for the TPA slurry is characterized in that the preparation device comprises a TPA slurry mixing tank (3), an IPA (isophthalic acid) mixing tank (5) and a TPA feeding tank (7), wherein a mass flow meter (6) is arranged between the TPA slurry mixing tank (3) and the TPA feeding tank (7); and the mass flow meter (6) is also arranged between the IPA slurry mixing tank (5) and a liquid inlet of the TPA feeding tank (7). The preparation device adopts the mass flow meter to control the proportioning of the slurry, so that the conventional weight flow meter and the twin-screw feeder are replaced, the problems of easy damage of the weight flow meter and the leakage and dust raising of the screw extruder during the feeding process can be avoided, the production cost is reduced, the production environment is not polluted, an
