Description

Technical Field

[0001] This utility model relates to the field of lignin modification mixing equipment, and more particularly to a lignin modification mixing equipment. Background Technology

[0002] Lignin is an amorphous aromatic polymer widely found in plants, whose molecular structure contains oxyphenylpropanol or its derivative structural units. The xylem of plants contains a large amount of lignin, which enables the xylem to maintain extremely high hardness to support the weight of the entire plant.

[0003] A search revealed a Chinese patent disclosure: a modified asphalt mixing and stirring device (authorization announcement number: CN214131430U). This utility model discloses a modified asphalt mixing and stirring device, belonging to the field of modified asphalt processing technology. The modified asphalt mixing and stirring device includes a housing with a mixing chamber in the center of the top surface. A discharge port is located at the lower end of the front wall of the housing, and an asphalt-specific valve is connected to the front end of the discharge port. Two shafts are symmetrically arranged through the upper part of the mixing chamber. The right end of each shaft extends through the inner wall of the mixing chamber and is fitted with a gear. A driven wheel is coaxially fixedly connected to the right end of the front shaft. A roller is fitted in the middle of the shaft. Multiple compaction rollers are linearly and equally spaced and staggered on the outer walls of the two rollers. A guide block is provided on the upper part of the outer side of each roller. A mixing assembly is located in the middle of the mixing chamber. This utility model can simultaneously crush and grind the filler material added to the mixing chamber using the rollers and compaction rollers, while thoroughly mixing the asphalt and filler mixture within the mixing chamber, saving time and labor, and is highly practical.

[0004] However, in the actual application of this patented technology, when stirring lignin, the existing equipment lacks an adjustment structure for the stirring device, making it impossible to stir lignin at different depths. This results in uneven stirring, which affects the later use of lignin. Utility Model Content
