Reaction equipment for preparing azamethiphos

The utility model provides reaction equipment for preparing azamethiphos. The reaction equipment comprises a first reaction unit, a second reaction unit and a third reaction unit which are respectively communicated with the first and second reaction units. The first reaction unit consists of a first reaction kettle, an oxazolo[4,5-b]pyridine-2(3H)-thione storage tank, an N,N-dimethylformamide storage tank and a paraformaldehyde storage tank. The second reaction unit consists of a second reaction kettle and a sulphur storage tank. The first reaction unit further comprises a first powder-liquid mixing pump, the oxazolo[4,5-b]pyridine-2(3H)-thione storage tank, the N,N-dimethylformamide storage tank and the paraformaldehyde storage tank are communicated with the first reaction kettle by the first power-liquid mixing pump. The second reaction unit further comprises a second powder-liquid mixing pump. The sulphur storage tank is communicated with the second reaction kettle by the second power-liquid mixing pump. T
