Problems solved by technology

[0002] Lignin is a complex class of organic polymers that form important structural materials in the supporting tissues of vascular plants and some algae, lignin is particularly important in the formation of cell walls, especially in wood and bark, Because they impart rigidity and are not easy to rot, the lignosulfonate further undergoes hydrolysis reaction in the acidic cooking liquid to depolymerize the hemicellulose combined with lignin, thereby dissolving the lignosulfonate and realizing the lignosulfonate Separatio

Abstract

The invention discloses a lignin purification method. An adopted device comprises a bearing barrel, a door plate is arranged at the top of the bearing barrel, a main shaft rotationally penetrates through the middle of the lower surface of the door plate in a sleeving mode, a plurality of stirring rods are symmetrically and fixedly connected to the bottom of the outer wall of the main shaft at equal intervals, and a bearing frame slidably sleeves an inner cavity of the bearing barrel; a filter screen is fixedly sleeved with an inner cavity of the bearing frame, a discharging hole is formed in the front face of the bearing barrel, a sealing plate is arranged on the front face of the bearing barrel, a sealing block is fixedly connected to the back face of the sealing plate, the outer wall ofthe sealing block is slidably sleeved with an inner cavity of the discharging hole, and sealing leather cushions are fixedly connected to the outer wall of the sealing block and the back face of the sealing plate. By means of the arrangement mode of the bearing barrel, the discharging holes are formed in the front face of the bearing barrel, so that the sealing plate is detached, impurities filtered on the filter screen can be removed, the production efficiency of the filter screen is improved, damage caused by frequent detaching of the filter screen can be reduced, and the practical performance of the filter screen is improved.
