AI Technical Summary

Technical Problem

In existing pulping equipment, low solid-liquid interface leads to low solid-liquid mixing degree and low mixing efficiency, which affects pulping efficiency.

Method used

A hybrid impeller is designed, including a spindle and an impeller body, with a conveying cavity on the spindle, a cavity is provided with an inner wall of the impeller body and a transmissible channel is provided with a side wall. The liquid flows from bottom to top in the delivery chamber, and after entering the cavity, it is dispersed again under the action of centrifugal force, and is thrown out through the overflow channel and mixed with the solid.

Benefits of technology

The height of the solid-liquid mixing interface is improved, the mixing degree and mixing efficiency of the solid-liquid are enhanced, and the pulping efficiency is improved.

Abstract

The invention relates to the technical field of pulping, and discloses a mixing impeller and pulping equipment. The mixing impeller comprises a main shaft and an impeller body; liquid enters the conveying cavity of the main shaft and flows from bottom to top, and the liquid flows from the conveying cavity into the cavity of the impeller body. During the rotation of the impeller, the liquid is dispersed again in the cavity under the action of centrifugal force, and a flow passage connected to the cavity is provided on the side wall of the impeller body. The liquid after redispersion is thrown out from the flow passage under the action of centrifugal force and mixed with the solid phase in the flow channel outside the impeller. The setting of the conveying cavity in the main shaft extends and raises the flow path of the liquid. After the liquid flows through the conveying cavity and the cavity, it is thrown out from the flow passage on the side wall surface of the impeller body, and the height of the mixing interface between the liquid and the solid is increased. In addition, the cavity can increase the dispersion of the liquid, so that the mixing of the solid and the liquid is more sufficient, the mixing quality is improved, and the mixing efficiency is further improved.
