Polymer dispersing device

A polymer dispersing device relates to the technical field of oil extraction. An inner hole of the barrel is in clearance fit connection with a material distributing roller, the material distributing roller is connected with a shaft through a flat key, containing grooves which are evenly distributed in the circumference are machined in the outer circle of the material distributing roller, the upper portion of the barrel is connected with a hopper through a flange, the barrel is provided with a feeding channel below the hopper, the lower portion of the barrel is provided with a discharging pipe, and a water inlet hole is formed in one side of the discharging pipe. The device has the beneficial effects that the rotary material distributing roller and the containing grooves are arranged, each containing groove can carry one polymer particle when rotating to the feeding channel, the polymer particles fall down and are mixed with water when the polymer particles are rotated to the discharging pipe through the mate
