Small-flow solid particle flow meter

The small-flow solid particle flow meter comprises a box body, a rotating assembly and a special-shaped funnel, the rotating assembly and the special-shaped funnel are installed in the box body, and an inlet connecting pipe is arranged on the outer side of the top of the box body; the rotating assembly comprises a rotating shaft installed on the box body, a rotating disc fixed to the rotating shaft and at least one metering barrel evenly distributed along the circumferential edge of the rotating disc. And the special-shaped funnel is positioned on one side of the rotating shaft and is used forreceiving solid particles in the metering barrel. Compared with the prior art, the small-flow solid particle flow metering device has the advantages that small-flow solid particle flow metering and adjusting are achieved, the small-flow solid particle flow metering device is suitable for metering solid particles or powder flow of various densities and is not limited by high temperature and otherenvironmental conditions,
