[0002] Waste paper processing is the process of reprocessing recycled waste paper to obtain qualified fibers for the production of paper products. The recycling and utilization of waste paper is beneficial to protecting the environment, protecting forests and saving resources. Waste paper can be reused many times. After the waste paper is recycled, it needs to be stirred into pulp by a machine. However, when the machine stirs, the pulp tends to settle at the bottom, so anti-sedimentation equipment is needed.

[0003] At present, most paperboard pulp mixing equipment for papermaking does not have an anti-sedimentation device. When mixing the recycled waste paper, the pulp is easy to settle at the bottom of the equipment, resulting in uneven mixing. Moreover, the mixing device itself does not have a cleaning mechanism. When the pulp is stirred, pulp is easy to remain on the inner wall of the equipment, resulting in the inconvenience of cleaning the equipment, which has great limitations.

[0004] Therefore, those skilled in the art provide a paperboard pulp stirring and anti-sedimentation device for papermaking to solve the problems raised in the above background technology. Utility Model Content
