Description

Technical Field

[0001] The utility model relates to the technical field of polypropylene production, and particularly relates to a polypropylene impurity removal and adsorption molecular sieve. Background Technique

[0002] The polypropylene impurity removal and adsorption molecular sieve is an adsorbent specifically used for removing impurities in the polypropylene production process. During the synthesis and post-treatment of polypropylene, some by-products, catalyst residues, oxides, moisture, and other organic or inorganic impurities may be generated or mixed in. The presence of these impurities may affect the physical properties, processing properties, and the quality of the final product of polypropylene. There are usually two ways to use the molecular sieve in the polypropylene production: Static adsorption: Mix the polypropylene particles with the molecular sieve and let it stand for a period of time to allow the molecular sieve to fully adsorb the impurities. Dynamic adsorption: Set up a molecular sieve adsorption bed on the continuous production line. When the polypropylene particles or melt pass through the adsorption bed, the impurities are adsorbed by the molecular sieve. Therefore, using the molecular sieve for deep purification is a very important step.

[0003] When the existing polypropylene molecular sieve mixing device discharges the mixture, centralized separation is carried out through a separation net arranged at the discharge port of the mixing device. However, in this separation method, due to the narrow discharge port, the polypropylene molecular sieve is easily concentrated and blocked on the separation net. At this time, workers still need to use external dredging tools to dredge the blockage, which increases the workload of the workers. Moreover, the separated molecular sieve still needs to be recycled by the workers, which undoubtedly increases the process of repeated discharging operations and is not convenient to use. Therefore, we have proposed a polypropylene impurity removal and adsorption molecular sieve with the function of being easy to use and urgently need to be developed. Summary of the Utility Model
