Copper-nickel-cadmium removal reagent adding device

The utility model provides a copper, nickel and cadmium removal reagent adding device which comprises a main body, a bottom mounting frame is fixed below the main body, baffles are fixed on two sides of the bottom mounting frame, and a weighing and feeding mechanism is mounted above the bottom mounting frame. According to the copper-nickel-cadmium removal reagent adding device, the interior of the adding device body is used for containing copper-nickel-cadmium removal reagent particles, when a worker wants to put the reagent particles into a boiler to conduct copper-nickel-cadmium removal operation, opening of the discharging valve can be controlled at the first time, and a reagent is discharged from a valve opening to the position above a metering weighing scale which is arranged below in an aligned and preset mode; at the moment, reagent particles can be prevented from falling off due to blocking of pushing plates on the left side and the right side of the metering and weighing scale and limiting of baffles
