Multifunctional upward continuation device for producing antimonous oxide

The utility model relates to a multifunctional upward continuation device for producing antimony trioxide. The multifunctional upward continuation device comprises an inlet pipe, an abdomen pipe and an exhaust pipe which are sequentially connected and communicated, wherein the inner diameter of the abdomen pipe is greater than the inner diameter of the inlet pipe and the inner diameter of the exhaust pipe; the inlet end of the inlet pipe is mounted at the outlet end of an antimonous oxide reaction chamber; the outlet end of the exhaust pipe is connected with the inlet end of an antimonous oxide crystallizer. According to the multifunctional upward continuation device, the product granularity of the antimony trioxide can be arbitrarily regulated; the product quality of the antimony trioxide is effectively controlled; the crystallized oxygen generated during the production of the antimony trioxide is recycled in time. Thus, the technical and economical indexes such as the yield of the antimony trioxide and the
