Description

Device for producing crude ammonium perchlorate by cold double decomposition Technical Field The utility model relates to the technical field of ammonium perchlorate production, in particular to a device for producing crude ammonium perchlorate by cold double decomposition. Background Ammonium perchlorate is an important oxidant and is widely applied to the fields of solid rocket propellants, pyrotechnic compositions and the like. Traditional production methods include electrolytic methods and double decomposition methods, wherein the double decomposition method is widely adopted due to low cost and simple process. However, the existing double decomposition method has the problems of low crystallization efficiency, uneven heat transfer and limited crystal growth caused by easy scaling of the inner wall of the reaction kettle and the stirring part, low crystal recovery rate, and material waste caused by incapability of thoroughly removing crystals on the kettle wall and the stirring shaft by the traditional scraper. Disclosure of utility model The utility model solves the problems of uneven heat transfer and limited crystal growth caused by easy scaling of the inner wall and stirring parts of a reaction kettle and low recovery rate of crystals, and solves the technical problems that the traditional scraper cannot thoroughly remove crystals on the kettle wall and the stirring shaft, so that materials are wasted. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a cold method double decomposition production crude ammonium perchlorate device, includes the cauldron body, filling tube, charging valve, PH governing tank and discharge valve, filling tube and charging valve are installed to cauldron body lateral wall, the charging valve is connected with the PH governing tank, the discharge valve is installed to cauldron body bottom, the internal carousel of installing that rotates of cauldron, carousel downside rotates installs a plurality of (mixing) shaft, crystal removal mechanism that strikes off on cauldron body inner wall and the (mixing) shaft outer wall is installed to the carousel bottom. Preferably, a cooling pipe is arranged in the kettle body and is connected with the cooling device. Preferably, the turntable is connected with the kettle body through a bearing, and external teeth are arranged on the outer side of the turntable. Preferably, a motor is arranged on the kettle body, a rotating tooth is arranged at the output end of the motor, and the rotating tooth is meshed with the external tooth. Preferably, a pneumatic cylinder is arranged on the top side of the kettle body, and the telescopic end of the pneumatic cylinder penetrates through the center of the turntable and the lifting scraping disc to be connected in a rotating manner through a bearing.
