Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cross-linked polyvinylpyrrolidone production and processing, in particular to a purification device for cross-linked polyvinylpyrrolidone production. Background Art
[0002] Crospovidone is a solid polymer. It usually appears as a white to milky white powder. At room temperature, crospovidone is in a solid state with good solubility. It can be dissolved in water and many organic solvents. Due to its high molecular weight and cross-linked structure, crospovidone has good stability and solubility. It is widely used in the fields of medicine, cosmetics, food, etc. It is often used in the medicine, cosmetics and food industries. During its production process, purification is required to ensure the quality and purity of the product.
[0003] After searching, a potassium fluorotitanate refining and purification equipment with announcement number CN218189190U is found, including a potassium fluorotitanate refining and purification equipment, including an equipment body, and legs are fixed at the four corners of the bottom of the equipment body. The potassium fluorotitanate refining and purification equipment is used to drive the lever to stir, agitate and dry the potassium fluorotitanate solid when the internal shaft rotates. A fixed rod is fixed on one side of the second stirring rod, and multiple groups of wire brushes are fixed at equal intervals on one side of the fixed rod. When the shaft rotates, the wire brush can be driven to rotate inside the equipment body. The potassium fluorotitanate solid adhering to the inner wall of the equipment body can be swept and cleaned by the wire brush to keep the inside of the equipment clean, solving the problem of facilitating the cleaning of the potassium fluorotitanate material adhering to the inner wall of the equipment during the drying process.

If there are large particles or lumps in the cross-linked polyvinylpyrrolidone, it may increase the difficulty of subsequent processing. For example, unevenness or agglomeration may occur during the dissolution, mixing or granulation process, thereby affecting production efficiency and product quality. Therefore, in response to the above problems, a purification equipment for cross-linked polyvinylpyrrolidone production is proposed. Utility Model Content
