Description

Technical Field

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

[0002] Molecular sieves are solid materials with a highly regular microporous structure, typically composed of aluminosilicates or other porous substances. Their unique crystal structure results in uniform pore sizes, which precisely screen and adsorb molecules of specific sizes. Due to their excellent selective adsorption properties, molecular sieves are widely used in processes such as gas and liquid separation, purification, and drying, playing a particularly important role in the chemical, pharmaceutical, and petrochemical industries. However, after production, the pore structure of molecular sieves is easily occupied by moisture or other impurities, resulting in a decrease in adsorption performance. Therefore, ensuring the dryness and proper storage of molecular sieves is key to maintaining their efficient adsorption capacity.

[0003] The patent with publication number CN214268398U discloses a molecular sieve drying storage box, including a storage box cover, a stacking bracket, a handle groove, a storage box cover buckle, a device touch panel, a storage box body, a working status indicator light, a side handle and a dryer loading window. The storage box body is connected to the storage box cover through several steel hinges. Several stacking brackets are respectively installed on the upper part of the storage box cover and the lower part of the storage box body. More than two grooves are opened on the upper part of the storage box cover to install the handle grooves respectively. The front surface of the storage box cover is provided with a storage box cover buckle, which can provide a constant storage environment for the molecular sieve so that the molecular sieve can be kept in a standby state for a long time.

[0004] In practice, the above-mentioned prior art primarily relies on an internal air flow pump to generate airflow, which is then absorbed by a dehumidifier to achieve dehumidification. While this method can reduce ambient humidity to a certain extent, it relies on ambient airflow to effectively and thoroughly dry the moisture within the molecular sieve. This is particularly true in high-humidity environments, where the dehumidification effect is often unsatisfactory, resulting in a prolonged drying time for the molecular sieve and a reduction in its efficiency. In light of this, we propose a molecular sieve drying and storage device. Utility Model Content
