Description

Technical Field

[0001] This utility model relates to the technical field of ammonium perchlorate production equipment, and in particular to an ammonium perchlorate crystallization device with a rate control mechanism. Background Technology

[0002] Ammonium perchlorate crystallization refers to the process of crystallizing from an ammonium perchlorate solution through methods such as cooling or evaporating water. Commonly, this is done in a crystallization vessel with heating and stirring to obtain crystals. For example, application number CN201920319839.X discloses a lithium hexafluorophosphate stirring crystallization device. This device uses a specially structured impeller for stirring and employs a frequency converter to control the stirring mode and speed, controlling the cooling rate of the crystallization based on the stirring speed. However, during the crystallization process, the material changes from liquid to solid, and the output torque on the connecting rod connected to the impeller increases accordingly. If the motor's output power is controlled by a frequency converter, long-term operation can easily cause motor overload and damage. Utility Model Content
