Cellulose pulp pretreatment equipment

The invention provides cellulose pulp pretreatment equipment, which comprises a vertical stirring kettle. A kettle cover is arranged above the kettle body, a motor is disposed on the kettle cover and is connected to a stirring shaft, and the stirring shaft extends into the kettle body and is provided with stirring paddles. A porous pressing plate is disposed above the stirring paddles in the kettle body and is equipped with a center through hole, and the stirring shaft runs through the center through hole. The porous pressing plate matches with the kettle body cross section. The porous pressing plate is equipped with a plurality of holes, and can move up and down in the kettle body. According to the invention, the porous pressing plate can complete the technological requirements of pressing the pulp into a solvent. Pulp impregnation solvent swelling, mixing and pulping are finished in one kettle, equipment investment and engineering investment are saved, the manufacturing, energy consumption and management costs are saved, and the cellulose pulp pretreatment process is shortened.
