Flash dryer with adjusting function for magnesium hydroxide production

The utility model provides a flash dryer with an adjusting function for magnesium hydroxide production, and relates to the technical field of flash dryers, the flash dryer comprises a drying cylinder and an air blower, a stirring assembly is arranged in the drying cylinder, and a discharging pipe is fixedly connected to the position, close to the right side, of the outer surface of the drying cylinder. The telescopic rod drives the rack to move up and down so as to drive the first gear to rotate, all the flow plates are driven to rotate synchronously through mutual matching of the second gear and the transmission toothed belt, when all the flow plates tend to be horizontal, the discharging flow is the maximum, and when all the flow plates tend to be vertical, the discharging channel is closed. When materials cannot be discharged into the discharging pipe, the discharging flow of the materials can be controlled by controlling the movement amount of the telescopic rod, so that the retention time of the material
