Energy-saving sodium acetate rapid drying equipment and drying process thereof

Abstract

The invention relates to the field of chemical product drying, in particular to energy-saving sodium acetate rapid drying equipment and a drying process thereof. The drying equipment comprises a rack, a crushing and grinding device and a drying device, the drying device dries crushed and ground materials, the crushing and grinding device comprises a material bin, a rotating shaft, an inner elastic frame and an outer elastic frame, the inner elastic frame comprises an upper ring, a lower ring and an inner elastic strip, the outer elastic frame comprises an upper plate, a lower ring and an outer elastic strip, a discharging port is formed in the material bin, and a feeding port is formed in the upper plate. When ground materials are increased to enable the lower ring to move downwards or grinding resistance is increased to enable the lower ring to rotate, the upper plate can rotate, the discharging port and the feeding port are staggered, the feeding amount is reduced, meanwhile, the upper plate rotates to drive the upper ring to rotate, the inner elastic strip contracts inwards, the gap between the inner elastic strip and the rotating shaft is reduced, the crushing strength is increased, and therefore through cooperation of the inner elastic frame and the outer elastic frame, the feeding amount and the crushing strength are automatically controlled according to the grinding condition, the crushing effect is improved, and the drying effect is guaranteed.

Description

technical field [0001] The invention relates to the field of chemical product drying, in particular to energy-saving sodium acetate rapid drying equipment and a drying process thereof. Background technique [0002] Anhydrous sodium acetate is colorless transparent crystal or white granules, which can be weathered in the air, and has hygroscopicity and flammability. Drying of anhydrous sodium acetate is an essential process in the production process. [0003] Because there are many problems in the crystallization operation of existing sodium acetate, such as: uneven stirring of the feed liquid, crystals are easy to hang on the wall during the crystallization process, low production efficiency, long crystallization time, uneven distribution of product particles, high proportion of small particles, etc., resulting in acetic acid After sodium crystallization, hardening is easy to form, which will affect the subsequent drying process. Therefore, it is necessary to first crush the...
