Sodium hydride dryer

 
White to light gray fine crystals, dispersed in oil at a ratio of 60% to 65%, decomposed at 800 ° C, flammable when wet. Sodium hydride is most commonly used for the deprotonation of 1,3-dicarbonyl compounds, maleates and similar compounds, and the corresponding sodium compounds can be alkylated to produce a wide variety of organic compounds. Corresponding reactions can be found in the Dieckmann condensation reaction, the Stobbe condensation reaction, the Darzens condensation reaction and the Claisen condensation reaction; it is also used to synthesize sulfur ylide to effect the conversion of ketones to epoxy compounds.

 
The  type vacuum dryer comprises a casing, and left and right sides of the casing are respectively provided with a left rotating shaft and a right rotating shaft which are rotated by a motor, and a left rotating sleeve is arranged on the outer side of the left rotating shaft, The outer side of the right rotating shaft is provided with a right rotating sleeve, the upper rotating sleeve is provided with a plurality of upper masts, the left rotating sleeve is provided with a plurality of lower masts, and the right rotating sleeve is provided with a plurality of upper right masts, There are several right lower masts arranged under the right rotating sleeve, and several adjacent upper right masts are respectively connected by the upper right connecting rod, and several adjacent right lower masts are respectively connected by the lower right connecting rod, the dryer The left and right rotating shafts rotate in opposite directions.


The sodium hydride sputum dryer has a simple structure and reasonable design, and changes the original single-rotation structure, which becomes a double rotation in the dryer body, speeding up the drying speed and drying evenly.


A mechanical device that vaporizes moisture in a material (generally referred to as moisture or other volatile liquid component) by heating to obtain a solid material having a specified moisture content, and has different types of dryers depending on the field of use. The type of dryer is mainly used in the fields of medicine, food, chemical industry, etc. Nowadays, the drier type dryer is generally driven by the same motor to drive the shaft. Although the mast and the caries can stir the material to speed up drying, but such The material is not uniformly stirred, the drying speed is slow, the drying effect is not satisfactory, and if a relatively viscous object is easily adhered to the inside of the casing of the dryer.
