AI Technical Summary

Problems solved by technology

[0002] The medium-consistency pulp tower is mostly used for pulp storage or bleaching. It includes a tower body, a pulp inlet arranged at the top of the tower body, a pulp outlet arranged at the bottom of the tower body, and a pulp outlet arranged at the bottom of the tower body cavity. The inner cavity at the bottom of the tower is divided into the central column of the annular inner cavity. The pulp propeller installed in the annular inner cavity at the bottom of the tower is used to make the pulp at the bottom of the tower rotate and flow, so as to ensure that the pulp is evenly mixed and reacts. Thorough and convenient pulping; the disadvantage of the existing technology is that the inner cavity of the pulp tower is connected from top to bottom. When the pulp propeller is pushing the pulp, the flowing pulp gradually transmits the kinetic force upwards, causing unnecessary swirling of the upper layer of pulp. It causes energy waste; and the pulp tower with this structure has a large starting resistance of the pulp propeller, which is easy to damage the propeller motor
