Description

Technical Field

[0001] The utility model relates to the technical field of papermaking machines, in particular to a pulping device for a pulp feeding box of a multi-disc thickener. Background Art

[0002] The multi-disc thickener is mainly used for the concentration and washing of pulp line slurry. The slurry flows into the slurry inlet box through the slurry inlet pipe, and then enters the slurry tank by overflow. When the central axis rotates, the fan-shaped plates on the disc (the disc is formed by the combination of fan-shaped plates and is in the shape of a disc) are immersed in the slurry under atmospheric pressure, and the slurry is separated by the filter medium. A vacuum is gradually formed inside the water retreat. At this time, the slurry layer adsorbed on the surface of the fan-shaped plate is relatively thin, and a large number of fine fibers and filler solids are still present in the filtered filtrate. The concentration of this part of the filtrate is relatively high, which is called turbid filtrate. As the fan-shaped plates continue to operate, the slurry layer on the fan-shaped plates gradually becomes thicker. At this time, the slurry layer itself plays the role of a good filter medium and can intercept A large amount of fine solids, the quality of the filtrate gradually improves, the filtrate in this area is called clear filtrate; with the rotation of the fan-shaped plate, the pulp layer thickens, and when the fan-shaped plate turns out of the liquid surface, it continues to dehydrate under the action of vacuum, and the dryness of the pulp layer is further improved, and then enters the atmospheric area, when the stripping water peels off the edge of the fan-shaped plate, the pulp layer forms a self-roll under the action of its own gravity, falls into the pulp trough, and is spirally transported into the pulp pool. The fan-shaped plate with the peeled pulp layer is transferred to the washing area, and enters the next filtration cycle after washing. The existing pulp inlet box homogenization device can control the stirring component to move horizontally and vertically in the pulp pool through the setting of the homogenization mechanism, so that different areas in the pulp pool can be fully stirred to improve the uniformity of the pulp in the entire pulp pool.

[0003] Due to the existing pulp inlet box homogenizing device, the stirring blades can only stir in the circumferential direction when in use. If there are lumps in the pulp, the lumps can only remain on a certain circular surface and roll repeatedly, and are not easy to disperse. In addition, the stirring force in the inner wall area of ​​the pulp pool is not high, and the lumps on the inner wall surface are not easy to fall off, making it still inconvenient to use. Utility Model Content
