Abstract

The invention relates to an anchor type stirring device, which comprises a stirring shaft, wherein the lower end of the stirring shaft is provided with an anchor type stirring paddle; two connecting arms are arranged between the stirring shaft and the anchor type stirring paddle; each connecting arm is a downwards pushing inclined blade; two short downwards pushing inclined blades are arranged in the positions of the connecting arms of the stirring shaft in the direction vertical to the plane of the anchor type paddle blades; the inclination angle of the downwards pushing inclined blades and the short downwards pushing inclined blades is 40 to 50 degrees; the diameter of each short downwards pushing inclined blade is 0.4 to 0.5 times of the diameter of the anchor type paddle blades. The anchor type stirring device has the advantages that materials can be promoted to be integrally and uniformly mixed; the evaporation concentration process is favorably, stably and uniformly performed; meanwhile, the stirring power consumption is reduced; the paddle blade or motor damage is reduced.

Description

technical field [0001] The invention relates to a stirring device, in particular to a stirring device for mixing materials with high solid content when preparing alkali metal alkoxides. Background technique [0002] The alkali metal alkoxide reaction kettle adopts anchor type or frame type stirring paddle. When the alkali metal alkoxide liquid is evaporated and concentrated in the later stage of the reaction, the viscosity of the reaction system increases continuously, especially in the later stage, a large amount of solid powder is generated, resulting in an increase in stirring power. , high power consumption. In addition, the increased viscosity of the system greatly increases the torque force of the agitator, causing the agitator to be deformed and damaged. These problems increase the energy consumption of the production process, increase the cost of equipment, and also affect the enlargement of the reactor. Anchor or frame impellers are usually used in the stirring pr...
