Description

Technical Field

[0001] The invention belongs to the field of molecular sieve production equipment, and more specifically, relates to a molecular sieve device with cooling and heat dissipation functions. Background Art

[0002] Molecular sieves, as a highly refined material, are unique in their special structure, which is artificially synthesized or derived from natural zeolites. This structure gives molecular sieves the extraordinary ability to screen molecules. The core lies in the carefully constructed pore system with uniform pore size and orderly arranged pore network. These microstructures are like the precision sieves in nature, which can efficiently screen and separate molecules according to their size and shape, thus showing a wide range of application prospects in many fields such as chemical industry, petroleum processing, gas separation and purification, etc.

[0003] At present, the preparation process of molecular sieves is relatively mature, mainly including the precise proportion and mixing of raw materials, granulation through a specific process to form the desired particle shape, fine screening to ensure the consistency of particle size, strict drying process to remove excess water and high temperature roasting to stabilize its crystal structure and enhance performance. However, in this series of complex and sophisticated preparation processes, the cooling link after roasting often becomes one of the bottlenecks to improve the overall efficiency.

[0004] Traditional cooling methods mostly use natural cooling at room temperature, that is, allowing the molecular sieve that has just been calcined at high temperature to cool down slowly at room temperature. Although this method is simple and easy, the cooling efficiency is low. On the one hand, it not only prolongs the production cycle, but also may cause adverse effects on the crystal structure of the molecular sieve due to long-term high-temperature exposure, thereby affecting its ultimate performance and service life; on the other hand, the cooling equipment in the prior art, such as the cooling tank, often needs to rely on manual operation to remove the molecular sieve from the tank after the molecular sieve is cooled; such operation is too complicated and cumbersome, resulting in poor cooling and heat dissipation efficiency of the molecular sieve.
