Abstract

The application relates to the technical field of sodium hydroxide dilution, and discloses a precise metering device for sodium hydroxide diluent, which comprises a diluent metering tank, the outer wall of the diluent metering tank is provided with a display, the top cover of the diluent metering tank is provided with a sealing cover, a group of flow guide pipes are circumferentially equidistantly arranged at the top end of the sealing cover, a feeding metering hopper is fixed to the top end of the flow guide pipe, a group of shunt pipes are equidistantly distributed on the outer wall of the bottom end of the diluent metering tank, a shunt metering pipe is connected to the output end of the shunt pipe, and an adjusting valve is arranged on the shunt metering pipe. The precise metering system is formed by the feeding metering hopper, the pressure sensor and the display, so that the raw material ratio is accurate; the stirring shaft, the mixing blades, the stirring claws and the scraping pieces are matched to realize omnibearing and dead angle-free mixing of the diluent, and the concentration is uniform. The shunt pipe and the shunt metering pipe with a scale bar flexibly control the flow through the adjusting valve, and the diversified distribution requirements are met.
