The present embodiment reduces unnecessary resistance to the slurry and enables more uniform and stable output of the slurry by new improvements, so that a two-part separated structure is specially formed, namely, a special stirring blade t701 stirs and a special slurry scoop t702 scoops the slurry out.

It is mainly noted here that the stirring blade t701 is vertical and is integrally kept vertical to the stirring rotation shaft t7, while the slurry scooping member t702 is similar to a water scoop in structure and keeps away from the stirring rotation shaft t7 as far as possible, so that the water scooping effect can be achieved, the axial dimension of the middle part is reduced, and the effects of reducing resistance and scooping water can be achieved.

The pulp scooping cylinder t7022 should be a cylinder structure with the bottom closed and the top opened, and it is preferable that the opening of the pulp scooping cylinder t7022 is oriented such that when the connecting arm t7021 is rotated to the front horizontal position, that is, to the position near the front overflow port t60, the opening of the pulp scooping cylinder t7022 is directed forward and upward and toward the front overflow port t60, so that the pulp is scooped optimally, and the pulp scooping cylinder t7022 is inclined forward and upward with respect to the design of the connecting arm t7021 of more than 90 degrees, that is, when the connecting arm t7021 is in the horizontal state. Still further, the pulp scooping barrel t7022 is open at the top and is in a truncated cone shape with the diameter gradually increasing from bottom to top, the pulp scooping barrel t7022 is in a horn-like structure, so that pulp scooping can be carried out more and more in a guiding manner, the pulp scooping barrel t7022 can be integrally formed with the connecting arm t7021, and when the pulp scooping barrel is in operation, the pulp scooping tool t702 is observed on the right side of the equipment and is rotated anticlockwise.

Preferably, the front area of the front side groove wall of the pulp overflow temporary storage tank t6 is provided with a protective baffle t600 at the positions of two sides of the front side overflow port t60 respectively, the protective baffle t600 can be directly installed and connected on the front side part of the pulp overflow temporary storage tank t6, and the pulp overflow temporary storage tank is mainly used for preventing pulp from being scattered to two sides and ensuring that the pulp can be effectively filtered and dehydrated.

Further, the stirring blades t701 at the leftmost side and the stirring blades t701 at the rightmost side are both spiral blades and feed toward the center of the pulp overflow temporary storage tank t6, and as mentioned above, each stirring blade t701 is vertical as much as possible, while in order to better match the structure of the embodiment, the stirring blades t701 at the leftmost and rightmost sides are spiral blades, which are similar to the existing propeller blades, so that the pulp has better stirring effect in the axial direction, namely a dynamic system is formed from the pulp, the pulp at the leftmost and rightmost sides leans towards the middle, the middle flows up and down and goes to the leftmost and rightmost sides, a flowing loop is formed in a three-dimensional space, so that the components in the pulp are in a relatively uniform state, and the uneven problems such as paper grain accumulation are not easy to occur. While the stirring blade t701 positioned between the left and right can also adopt a spiral blade for discharging to the center, other stirring blade structures without axial guiding capability can be adopted, and only the stirring in the circumferential direction can be adopted.

Through these specific settings, just can make and get effectual stirring and output after the thick liquids get into paper pulp overflow temporary storage pond t6 for the quality of thick liquids is better, and the operation can be more smooth, just can filter the dehydration after the thick liquids reaches filtering mechanism on, just can be better.

Of course, the present embodiment also provides a paper medium processing apparatus including the dewatering device of the present embodiment, and of course, the paper medium processing apparatus may also include a pulp dissolving device capable of feeding pulp into the pulp overflow temporary storage tank t6, and the like, which has a very good use effect.

While the utility model has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
