Chemical reagent drying device

Abstract

The invention discloses a device for drying a chemical reagent. The device is used for drying a granular or powdery solid chemical reagent. The device comprises a drying box, a feeding port is formed in the top of the drying box, a discharging port is formed in the bottom of the drying box, and an assembly for drying reagents after heating is arranged in the drying box. The assembly comprises two drying hoppers, the drying hoppers are transversely and horizontally arranged, the first ends of the two drying hoppers are seamlessly connected and communicated, the second ends of the two drying hoppers are rotatably connected to drying boxes through first rotating shafts, and the drying boxes are supported through electric telescopic rods. The drying box can be driven to rotate around the first rotating shaft through stretching and retracting of the electric telescopic rod. The bottom plate of the drying hopper is of a wave-shaped structure, by means of the structural characteristics of continuous wave crests and wave troughs, reagents make full and even contact with the heating bottom plate in the continuous stirring, climbing and downhill processes of the reagents, the reagent drying efficiency and effect are improved, and the experiment accuracy can be guaranteed.

Description

technical field [0001] The invention relates to the field of chemical laboratory appliances, in particular to a device for drying chemical reagents. Background technique [0002] Chemical reagents are relative standard substances for chemical research and component analysis, and are an important condition for scientific and technological progress. They are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. They are used in the daily work of factories, schools, hospitals and research institutes. Inseparable from chemical reagents. [0003] Many chemical reagents have strict requirements on the storage environment. When the reagent is placed in the air, the reagent will absorb water and become damp. When it is weighed accurately, the reagent content of the same quality will be less, and even the reagent will undergo a chemical reaction. changes that affect experimental data.

AI Technical Summary

Problems solved by technology

[0003] Many chemical reagents have strict requirements on the storage environment. When the reagent is placed in the air, the reagent will absorb water and become damp. When it is weighed accurately, the reagent content of the same quality will be less, and even the reagent will undergo a chemical reaction. Changes that affect experimental data

[0004] In particular, solid chemical reagents generally need to be dried. Existing equipment for drying solid particles and powder chemical reagents has drying blind spots, uneven contact between reagents and heat sources, and low drying efficiency.
