[0033] ​When working, the metering controller measures according to the proportioning of the boiler water treatment agent, and when working, the rotary metering valve 4 works, which can send the solid raw material components in the closed tank body 5 into the feeding pipe 1. When feeding, the excess solid raw material components are temporarily stored in the buffer pipe 6. When metering, since the rotary metering valve 4 can complete volume metering once per rotation, the total solid raw material feeding amount can be obtained by counting the number of times of rotation of the rotary metering valve 4 and multiplying the volume of single rotation. When each group of components reaches the set solid raw material feeding amount, the water feeding unit works, and the pump set 2 extracts pure water from the pure water tank 3. The pure water sends the solid raw material components in the feeding pipe 1 into the production kettle. At the same time, the purge valve is opened, and the purge gas source purges the buffer pipe 6 through the purge valve and the first gas pressure pipe 12, so that the dust of the raw materials remaining in the buffer pipe 6 is blown into the feeding pipe 1, and finally is blown into the production kettle.
