The rotary feeder is composed of three parts, namely a main valve, a speed reducing mechanism, a protective device and the like, the main valve is composed of a shell, an end cover, an impeller, a bearing, an oil seal, a gas collecting pipe and the like, the rotary valve impeller selected and used is different according to different use working conditions, and the impeller has three forms under the common conditions: closed impellers, semi-open impellers and open impellers. The closed impeller consists of front and back cover plates and middle blades, and the semi-open impeller has no front cover plate and the open impeller has only one part of back cover plate. At present, impeller blades of a rotary feeder are welded on a shaft one by one, and an inner cavity of a valve body is divided into a plurality of small cavities by the blades; the material falls into the impeller cavity from an inlet above the valve body to form a material mass with a small cavity. When the materials are discharged from the valve body outlet, the materials are discharged in a lump. When the working condition demands continuous blanking rather than one batch, the requirement cannot be met. The rotary feeder is required to carry out feeding weighing measurement under certain working conditions, and when the measurement precision requirement is higher, the weight of each mass of materials is far greater than the measurement precision requirement, so that the actual requirement cannot be met. Therefore, if a novel impeller form can be provided, continuous blanking and measurement accuracy meeting can be met, and the novel impeller form has very important significance.
