Pressure self-balancing steady-state stirring device

The pressure self-balancing steady-state stirring device comprises a stirring barrel and a pressure relief assembly, the pressure relief assembly comprises a pressure relief pipe with one end communicated with the upper portion of the stirring barrel and a dust removal component communicated with the other end of the pressure relief pipe, and the pressure relief pipe is connected with a pressure relief opening formed in the upper end of the stirring barrel. The pressure relief opening is far away from a powder inlet which is formed in the upper end of the stirring barrel and is used for feeding cementing powder. The stirring barrel is communicated with the outside by arranging the pressure relief pipe, so that the pressure at the upper part in the stirring barrel is released from the pressure relief pipe, the balance of the pressure inside and outside the stirring barrel is realized, and the continuous and steady-state blanking of each component material is ensured; the problems that due to the fact that the
