The utility model provides a high-pressure jet mixing device for polycarboxylate superplasticizer production, which comprises a reaction kettle, a jet pipe and a circulating pump, the top of the reaction kettle is provided with a manhole, the lower part of the reaction kettle is provided with the jet pipe, a feed pipe is arranged below the jet pipe, one end of the feed pipe is connected with the reaction kettle, the other end of the feed pipe is connected with the circulating pump, and an inlet of the jet pipe is connected with a discharge pipe. The other end of the discharge pipe is connected with the circulating pump. Liquid mixed materials in the reaction kettle are driven by the circulating pump to circulate through the feeding pipe and the discharging pipe and are sprayed out through the Venturi nozzle on the jet pipe, the materials are sprayed out from the conical nozzle at a high speed, a low-pressure area is formed around a guide opening of the Venturi nozzle, the area pressure difference and the liqu
