Description

Technical Field

[0001] The utility model relates to the technical field of pulp processing equipment, in particular to a stirring device for pulp bleaching. Background Technique

[0002] The unbleached pulp is treated with a bleaching agent to remove the colored substances and other sundries in the pulp to improve the whiteness and purity. This kind of pulp is bleached pulp. After bleaching, the use of the pulp is expanded, and various high-grade papers and refined pulp can be produced. Due to the different properties of the bleaching agents, the action principles on the pulp are also different. Oxidizing bleaching agents can not only remove colored substances, but also further remove residual lignin and other sundries, improving the whiteness and purity of the pulp and making the whiteness persistent. For high-yield pulps such as groundwood pulp and semi-chemical pulp, reducing bleaching agents can only decolorize the coloring substances and will not cause loss of fiber components, maintaining the original properties of the pulp, but the whiteness is not persistent and it is easy to turn yellow, so it is not suitable for making papers that need to be retained for a long time.

[0003] In pulp bleaching, the bleaching agent needs to be mixed with the pulp. The stirring effect of the existing stirring devices is poor, which easily causes the pulp to accumulate inside the device and cannot be fully mixed with the bleaching agent, resulting in a very poor bleaching effect of the pulp.
