Special additive dripping tank for preparing ion exchange resin catalyst

The utility model discloses a special assistant dripping tank for preparing an ion exchange resin catalyst, and relates to the technical field of resin catalysts, the special assistant dripping tank comprises a main body and a quantifying mechanism, and the quantifying mechanism is arranged on the front side of the main body. According to the resin catalyst feeding device, the situation that too much resin catalyst is added, so that the densities of processed objects are different, and produced objects are unqualified is avoided, firstly, the resin catalyst enters a material tank through a discharging pipe, and at the moment, a micro motor is started and drives a ball screw to rotate through a first rotating shaft; the rotating ball screw drives the ball nut, the supporting rod and the extrusion block to fall downwards, meanwhile, the extrusion block extrudes downwards on the inner wall of the material tank, the cover plate is opened downwards under the action of pressure, the resin catalyst is discharged dow
