Description

Technical Field

[0001] The utility model relates to the technical field of temperature monitoring, in particular to a molecular sieve heating waste nitrogen temperature point monitoring and alarm device. Background Art

[0002] Molecular sieves are synthetic hydrated aluminosilicates or natural zeolites that have the ability to screen molecules. They possess numerous uniformly sized channels and neatly arranged pores, enabling them to separate and screen molecules based on their size, shape, polarity, and degree of unsaturation. Molecular sieves are widely used in the chemical industry, environmental protection, soil improvement, water desalination, and radioactive chemistry, among other fields, for their primary functions, including adsorption, catalysis, drying, vacuuming, separation, and purification.

[0003] An existing Chinese utility model patent with reference publication number CN211628386U discloses an alarm device for monitoring the internal temperature of a molecular sieve oxygen production system. The device comprises a main body, a support member, a connector, and a locking member. The main body is fixed to the top of the connector, which is connected to the support member. Locking members are fixed to both sides of the support member. The locking members include a housing, a pin, and a spring. The housing has a through-slot internally configured, and connecting ears are integrally formed on both sides of the housing. Each set of connecting ears has two sets of through holes. A stopper is integrally formed at one end of the pin. The stopper is connected to a guide rod on the side away from the pin. The end of the guide rod, away from the stopper, extends through the housing and is connected to a circular ring outside the housing. A spring is mounted on the guide rod. This alarm device for monitoring the internal temperature of a molecular sieve oxygen production system is easy to install and disassemble, saving time.

[0004] Existing temperature monitoring and alarm devices are generally integrated. Since the steam flow direction needs to be restricted by the pipeline structure when the molecular sieve is used, so that the steam passes through the molecular sieve, the integrated temperature monitoring and alarm device cannot be installed inside the pipeline. At the same time, existing temperature monitoring and alarm devices generally use thermistors to realize the conversion between temperature signals and electrical signals. When in use, thermistors are generally wrapped by metal structures, resulting in a decrease in sensitivity. Utility Model Content
