This invention discloses a mixing impeller and a pulping device. The mixing impeller includes an impeller body with a cavity extending from its bottom end towards its top end. A flow-through hole communicating with the cavity is formed on the side wall of the impeller body. The impeller body can rotate around its own axis. During rotation, solid material is conveyed from top to bottom along the external flow channel of the impeller body; liquid material is conveyed from bottom to top through the cavity of the impeller body. The liquid material flows through the cavity and exits through the flow-through hole on the side wall of the impeller body, mixing with the solid material. The cavity and flow-through hole on the impeller body raise the liquid level, thereby increasing the mixing interface height between the solid and liquid materials and further improving the mixing efficiency.

The invention belongs to the field of pulping and papermaking, and particularly relates to an efficient cotton pulp cooking method based on fiber wax coat pretreatment. According to the method, the cotton fiber raw material is effectively pretreated to remove a wax coat on the surface of the fiber, so that the hydrophilicity and the liquid medicine permeability of the fiber are improved. The method comprises the following steps: carrying out infiltration expansion treatment on a cotton fiber raw material to loosen a fiber structure; then, an alkaline solution and / or enzyme are / is adopted for removing a wax layer on the surface of the cotton fiber; and washing, neutralizing and then carrying out conventional alkaline cooking. Through the pretreatment process, the wax coat on the surface of the cotton fiber is effectively stripped, the surface energy of the fiber is obviously improved, the liquid medicine can quickly permeate into the fiber, and the cooking reaction is more uniform, so that the comprehensive effects of shortening the cooking time and improving the slurry yield are realized. The method is easy and convenient to operate, low in environmental load and suitable for the preparation process of high-quality cotton pulp and specialty paper raw materials.

This invention discloses a shearing and dispersing device and a continuous pulping equipment. The shearing and dispersing device includes a cylinder, a stator unit, and a rotor unit. The stator unit and the rotor unit are alternately installed in the cylinder. The rotor unit is fixedly sleeved on the shaft core. The stator unit has multiple first through holes along its own axial direction, and the rotor unit has multiple second through holes along its own axial direction. When the driving component drives the shaft core to rotate, it drives the rotor unit to rotate, so that the multiple first through holes and multiple second through holes are interleaved. When the rotor unit rotates relative to the stator unit, a large shearing force is formed at the connection between the first through holes and the second through holes. As the pulp flows from the first through holes to the second through holes, it is sheared and dispersed to improve the dispersion of the pulp. The multiple stator units and multiple rotor units are alternately arranged, and the shaft core drives the rotor unit to rotate, which shears the pulp and promotes the flow of the pulp at the same time, so as to achieve the purpose of rapid and continuous pulping and improve pulping efficiency.
