Background In the ammonium molybdate production process flow, efficient material conveying is a key link for guaranteeing continuous and stable production. At present, the guide mechanism who adopts in the trade mostly is single spiral propelling movement structure, and it promotes the material through rotatory helical blade along body axial displacement, and this structure obtains wide application because of simple and reliable, but current single spiral conveying structure still can have following problem when using: however, ammonium molybdate materials are very hygroscopic and harden during storage and transport, resulting in frequent plugging of the single screw structure during operation. Once the blockage occurs, the rotation resistance of the spiral plate is suddenly increased, the conveying efficiency is rapidly reduced, the mechanism cannot dredge the blockage part by itself, and the mechanism must be stopped for manual cleaning, so that the use is very inconvenient. And when the material blocking situation is aggravated and a serious blocking phenomenon occurs, the spiral pushing mechanism is completely locked. At the moment, the driving motor enters a locked-rotor state due to overlarge load, current rises sharply, and if the power supply is not cut off in time, the motor is extremely easy to overheat and burn out, so that the maintenance cost is high, and serious potential safety hazards are brought to continuous production.
