Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifugal pulverizer technology, specifically a centrifugal pulverizer for molecular sieve raw materials. Background Technology
[0002] The main raw materials for molecular sieves include sodium aluminate, one of the primary aluminum sources in molecular sieve synthesis. Aluminum plays a crucial role in the structure of molecular sieves, forming structural units such as aluminum-oxygen tetrahedra, which constitute the framework of the molecular sieve. Sodium silicate, as a silicon source, is used to form the silicon-oxygen tetrahedral structure in the molecular sieve. Silicon-oxygen tetrahedra and aluminum-oxygen tetrahedra are linked together by shared oxygen atoms, forming the basic framework structure of the molecular sieve. Liquid alkali acts as a mineralizing agent in the synthesis process, promoting the dissolution and reaction of sodium silicate and sodium aluminate, and adjusting the pH of the reaction system to favor the formation of molecular sieves.
[0003] Centrifugal pulverizers are needed in the production of molecular sieve raw materials. Utility model patent CN205288535U discloses a multi-stage centrifugal pulverizer, including a conveying mechanism connected to a pulverizing drum via a material discharge channel. The inner wall of the pulverizing drum is equipped with primary, secondary, and tertiary pulverizing teeth arranged sequentially from top to bottom. A main shaft is installed inside the pulverizing drum, and a primary, secondary, and tertiary rotating support plate is arranged sequentially from top to bottom on the main shaft. Each of the primary, secondary, and tertiary rotating support plates has a powder discharge port. A slurry scraper is located on the lower side of the main shaft. A powder outlet pipe is located at the bottom of the pulverizing drum. Feet are provided on the outer wall of the pulverizing drum. A motor drive mechanism for driving the main shaft is located on the lower side of the pulverizing drum. This method improves grain crushing efficiency and achieves good crushing results.
[0004] However, common centrifugal pulverizers have filters during multi-stage pulverization, and molecular sieve raw materials can easily clog the filters, affecting the pulverization effect. Therefore, a centrifugal pulverizer for molecular sieve raw materials is proposed to solve the problems mentioned above. Utility Model Content
