The invention provides multi-process impurity removal equipment for rapeseed. The multi-process impurity removal equipment for the rapeseed comprises a horn type feeding pipe, a magnetic separation device shell, a rapeseed spreading plate assembly, a magnetic belt, a transmission drum, a return drum and a belt outlet. The magnetic separation device shell is connected to the lower end of the horn type feeding pipe. The belt outlet is mounted in the magnetic separation device shell. The magnetic belt is arranged at the lower end of the magnetic separation device shell. The transmission drum is mounted in the left end of the magnetic belt. The return drum is assembled in the right end of the magnetic belt. The rapeseed spreading assembly is mounted in the magnetic separation device shell. The middle portion of the rapeseed spreading plate assembly is mounted above the magnetic belt. The lower ends of the two ends of the rapeseed spreading plate assembly are connected with the bottom of the magnetic separation device shell. The upper half portion of the transmission drum is mounted in the magnetic separation device shell. The lower half portion of the transmission drum is assembled below the magnetic separation device shell. The multi-process impurity removal equipment for the rapeseed solves the problem that metal impurities cannot be removed and is convenient to use and convenient to operate, production efficiency is improved, labor intensity is lowered, and water resources are saved.
