Mixture transportation leaking stoppage device for multiphase mediums and slurry mixing method

The invention belongs to the technical field of leaking stoppage machinery of drilling engineering and particularly relates to a mixture transportation leaking stoppage device for multiphase mediums and a slurry mixing method. The device comprises an electric control box, a conveying hopper, a stirrer special for leaking stoppage, a conveying device and a chassis. The stirrer special for leaking stoppage and the conveying device are connected to the chassis, the conveying device is located below the stirrer special for leaking stoppage, and the conveying hopper is connected to the right end ofthe chassis; the electric control box is installed at the left end of the chassis and connected with the conveying hopper, the stirrer special for leaking stoppage and the conveying device separately. The problems are solved that in the prior art, in the process of preparing leaking stoppage slurry, the slurry mixing time is long, the loss of a leaking stoppage material is large, large-particle materials cannot be mixed
