The utility model discloses a crushing device for preparing ultrafine guanidine nitrate, which comprises a feeding box, a cyclone separator and a dust collecting box. The feeding box and the cyclone separator are connected by a feeding pipe, and the cyclone separator and the dust collecting box are connected by a feeding pipe. The dust collecting box is equipped with a fire extinguisher with a temperature control switch, and the fire extinguisher is opened/closed by a temperature control switch. The dust collector is equipped with a temperature control tester connected with a temperature control switch. If the temperature of the temperature control tester exceeds the set value, the temperature control switch opens the fire extinguisher. If the temperature of the temperature control tester is lower than the set value, the temperature control switch closes the fire extinguisher. The utility model sets a fire extinguisher controlled by a temperature control tester on the dust collector. When the temperature of the temperature control tester exceeds the set value, the temperature control switch opens the fire extinguisher, and when the temperature of the temperature control tester is lower than the set value, the temperature control switch closes the fire extinguisher, which can effectively avoid the high temperature and open ignition of guanidine nitrate production accidents and ensure the safety of personnel.

一种制备超细硝酸胍用粗粉碎装置
本技术属于化工设备领域,具体涉及一种制备超细硝酸胍用粗粉碎装置。
技术介绍
硝酸胍与盐酸胍、碳酸胍、磷酸胍是常用的四种胍盐,可用于生产磺胺脒、磺胺嘧啶等磺胺类药物和硝基胍、碳酸胍等胍盐的原料,也用于照相材料和消毒剂等。工业上通过双氰胺与硝酸铵反应制备硝酸胍成品。硝酸胍又名“硝酸亚氨脲”,有中等毒性,呈白色颗粒状,溶于水和乙醇,微溶于丙酮,在高温时分解爆炸。在受高热、猛撞或接触明火时,有引起燃烧爆炸的危险。与硫、磷及还原剂混合,有形成爆炸性混合物的危险。因此在硝酸胍生产的过程中怎样避免高温和明火成为研究的重点。
