Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve forming and drying, in particular to a molecular sieve forming and drying mechanism. Background Art

[0002] Molecular sieve is a synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. The production of molecular sieve starts with the preparation of raw materials. The main raw materials include kaolin, alumina, sodium silicate, etc. The raw materials are mixed evenly in a certain proportion and wet mixed with an appropriate amount of water or other solvents. Then, the materials are made into particles or spheres of a certain shape and size through molding processes such as extrusion, ball rolling or granulation. The formed molecular sieve particles will be dried to remove moisture and volatile organic compounds. However, when the formed molecular sieve is dried, if it is to be stacked, not only will it not be fully dried, but the molecular sieve pressed at the bottom may also be deformed or even cracked. In addition, the formed molecular sieve should also be avoided from stacking, otherwise, it will be deformed or even cracked. For this reason, we propose a molecular sieve forming and drying mechanism to solve these problems. Utility Model Content
