Description

Technical Field

[0002] At present, when producing water-soluble sulfonated phenolic resin, it is mainly prepared by condensing and sulfonating phenol, formaldehyde and sodium bisulfite, and then performing resinization and complexation reaction with water. Before sulfonation, phenol and sodium bisulfite need to be mixed according to a ratio.

[0003] In the prior art, when phenol and sodium bisulfite are mixed, phenol and sodium bisulfite with a good ratio are usually added to a vertically distributed mixing tank in sequence, and then the phenol and sodium bisulfite are stirred and mixed by a stirring mechanism arranged in the mixing tank. However, in the above method, in order to avoid affecting the rotation of the stirring mechanism, a certain gap is usually left between the bottom of the stirring mechanism and the inner bottom surface of the mixing tank. Since phenol and sodium bisulfite are both powdery materials, in the prior art, the powdery materials such as phenol and sodium bisulfite located at the bottom of the mixing tank cannot be stirred during mixing, so that the phenol and sodium bisulfite powdery materials cannot be mixed evenly; in addition, after the mixing of phenol and sodium bisulfite powdery materials is completed, it is not convenient to discharge the materials from the mixing tank. Therefore, there are still shortcomings and deficiencies in the prior art. Utility Model Content
