Description

Technical Field

[0001] This utility model relates to the field of pyrimidine compound production technology, and in particular to an extraction device for the production of pyrimidine compounds. Background Technology

[0002] An existing extraction device for producing pyrimidine compounds (publication number CN 217340150 U) involves feeding pyrimidine compounds and extractant into a mixing tank via feed pipes a and b. A servo motor drives a stirring paddle to rotate, mixing and extracting the extractant and pyrimidine compounds. This increases the extraction contact area between the extractant and the pyrimidine compounds, accelerating the extraction and increasing the extraction rate. However, this device only rotates the stirring paddle in one direction, resulting in poor mixing between the extractant and the pyrimidine compounds, increasing the mixing time, and affecting production efficiency.
