AI Technical Summary

Technical Problem

The existing lignin hydrolysis tanks lack supporting components for the stirring shaft, which leads to excessive motor load, affects rotation efficiency and may damage the motor. At the same time, the materials are not mixed evenly, affecting the reaction efficiency.

Method used

The long shaft driven by a servo motor is connected to the spiral stirring blades, and the stirring shaft is supported by a horizontal support rod and a conical cylinder structure. Combined with a temperature-controlled electric heater and an internal guide plate, stable stirring and temperature control are achieved, improving mixing uniformity and reaction efficiency.

Benefits of technology

It effectively disperses the weight of the stirring shaft, prevents motor damage, ensures stable rotation, improves the uniformity of material mixing and reaction efficiency, enhances unloading efficiency, and improves the quality and yield of hydrolysis products.
