Abstract

The invention provides cellulose pulp pretreatment equipment, including a vertical stirring kettle, a kettle cover is arranged above the kettle body, a motor is arranged on the kettle cover, the stirring shaft is connected with the motor, the stirring shaft extends into the kettle body, and the stirring shaft is provided with Stirring paddle, a porous pressing plate is provided above the stirring paddle in the kettle body, the porous pressing plate is provided with a central through hole, and the stirring shaft is set through the central through hole, the porous pressing plate is arranged in cooperation with the section of the kettle body, and the porous pressing plate is provided with There are many holes, and the porous pressing plate can move up and down in the still body. The beneficial effect of the present invention is that the porous press plate can complete the technological requirements of pressing the pulp into the solvent, and the swelling, mixing and pulping of the pulp soaked in the solvent are completed in one kettle, which saves equipment investment and engineering investment, and saves manufacturing and energy. Consumption and management costs are reduced, and the cellulose pulp pretreatment process is shortened.

Description

technical field [0001] The invention belongs to material mixing equipment, especially relates to a cellulose pulp pretreatment equipment, which is used for impregnating solvent, swelling, pulping and mixing of cellulose pulp, especially suitable for but not limited to the new solvent method cellulose fiber (Lyocell ) Pretreatment of cellulose pulp. Background technique [0002] The production of viscose fiber has gone through a history of more than one hundred years, and its existence has met the needs of human society to develop differentiated fibers to a certain extent. However, due to the use of a large number of environmentally harmful chemicals (such as CS 2 , NaOH, ZnSO 4 , H 2 SO 4 etc.), the sewage waste discharged in the production process also contains a large amount of toxic chemicals (such as H 2 S, CS 2 etc.), will cause huge pollution to the environment, and the cost of harmless treatment of these environmentally harmful chemical substances is very high, ...
