[0002] Purified terephthalic acid is an important organic chemical raw material with specific physical and chemical properties and a wide range of applications. When purified terephthalic acid is generated, crystallization separation is required. The crystallization separation process refers to the precipitation of solutes from the solution, which can be divided into two stages: nucleation and crystal growth. The driving force of both stages is the supersaturation of the solution. In this process, the raw materials and solutions used in the production of terephthalic acid need to be mixed. Previous crystallization separation devices usually use stirring to mix the two in a cylinder. During the stirring and mixing process, the mixture of the raw material and the solution will move toward the inner wall of the cylinder due to centrifugal force, and part of the mixture will adhere to the inner wall of the cylinder. The existing crystallization separation devices are often not convenient for cleaning the mixture adhered to the inner wall of the cylinder during the stirring process, thereby reducing the internal space of the cylinder.
