Reagent storage cabinet for laboratory

Abstract

The invention provides a reagent storage cabinet for a laboratory. The reagent storage cabinet comprises a cabinet body, wherein a plurality of partition plates are arranged in the cabinet body to divide the cabinet body into a plurality of independent storage chambers; a ventilation system which comprises an air inlet system and an air exhaust system, wherein the two side walls of the cabinet body are provided with an air inlet channel and an air exhaust channel respectively, the air inlet system is connected with the air inlet channel, and the air exhaust system is connected with the air exhaust channel, and airflow flows from the air inlet channel to the exhaust channel along the storage chamber corresponding to the air inlet channel; and a refrigerating system which is arranged at thebottom of the cabinet body and used for refrigerating the cabinet body, wherein a spiral air guide pipe is arranged in the refrigerating system, the air inlet end of the spiral air guide pipe is connected with the air inlet system, and the air outlet end of the spiral air guide pipe is connected with the air inlet channel. A plurality of independent airflow channels are formed by the ventilation system, the air inlet channel, the air outlet channel and the independent storage chambers. The airflow in the spiral air guide pipe is refrigerated through the refrigerating system so that the temperature of airflow flowing through each storage chamber in the cabinet body of the ventilation system is reduced, and safety and environmental protection are realized.

Description

technical field [0001] The invention belongs to the technical field of chemical experiment equipment, and in particular relates to a high-safety laboratory reagent storage cabinet. Background technique [0002] A large amount of chemical reagents are usually used in chemical experiments. Because different chemical reagents have different physical and chemical properties, two points should be paid attention to during storage: one is different cabinets for acids and alkalis; the other is the combination of upper solid and lower liquid in principle. When solid reagents and liquid reagents are stored in a reagent storage cabinet at the same time, since the liquid reagents at the bottom of the reagent storage cabinet are constantly volatilizing, the solid reagents at the top of the reagent storage cabinet tend to be affected as the storage time prolongs, and the occurrence is slow. Chemical reactions, such as decomposition, changing chemical properties, etc.; or physical reactio...

AI Technical Summary

Problems solved by technology

In addition, a variety of liquid reagents are stored in the reagent storage cabinet for a long time. With the mixing of the volatilized liquid reagents, certain chemical reactions often occur in the air, and even due to the concentration of the flammable liquid volatilized into the reagent storage cabinet Excessively high and prone to fire and other safety hazards

[0003] In order to solve the above potential safety hazards, a ventilation system is currently installed in the reagent storage cabinet. However, the air flow of the ventilation system is from the bottom side of the reagent storage cabinet to the top of the reagent storage cabinet, and there is still an air flow from the liquid reagent to the solid reagent. The long-term storage of solid reagents is affected by the tendency of flow
