[0002] A lot of waste paper is generated in the papermaking process. The waste paper is divided into dry waste and wet waste. Dry waste refers to the waste paper generated in the dryer section and later of the paper machine, including the waste paper generated in the dryer section when the paper machine breaks, the paper edges cut off after rewinding after soft pressing, the waste paper generated during packaging, and the defective products with quality problems, etc. Generally, it passes through the waste paper machine and then through the refining and pulping for repulping. Wet waste refers to the waste paper generated in the wet section (wire section, press section). Generally, it directly enters the wet waste pond and is adjusted to a certain concentration for repulping after passing through the pulper under the wet waste pond.

[0003] At present, most of the openings of the sizing waste paper pond are open designs and lack inlet protection devices. However, there is a stirrer installed inside the waste paper pond, which is a rotating cutter. Since these cutters are very sharp, there are certain safety risks during the process of pouring waste paper into the waste paper pond.
