Problems solved by technology

The cooked slurry in the cooking tube is discharged from the bottom of the cooking tube. Since the cooked slurry has a high concentration and contains impurities, if it is directly discharged from the cooking tube, the pulp with a high concentration will block the pipes, additionally, impurities in the slurry can affect the quality of the pulp

Abstract

The invention discloses a vertical discharging device of a continuous digester. The vertical discharging device comprises a shell, an electromotor, a vertical shaft and scraping plate impellors, wherein the upper part of the shell is provided with a slurry inlet, and a slurry outlet is formed in the one middle side of the shell; the electromotor is installed on the bottom of the shell; the output end of the electromotor is connected with the lower end of the vertical shaft; the vertical shaft extends into the shell; the scraping plate impellors are connected to the upper end of the vertical shaft; the shell is provided with diluted liquid receiving pipes and an impurity discharging pipe connected with the bottom of the shell. The vertical discharging device of the continuous digester can be used for smoothly discharging slurry, and moreover can be used for removing impurities in paper slurry.

Description

technical field [0001] The invention relates to a digester device, in particular to a vertical unloading device for a continuous digester. Background technique [0002] Paper is one of the four great inventions of ancient China. Together with the compass, gunpowder and printing, it provided the material and technological foundation for the prosperity of ancient Chinese culture. The invention of paper ended the complicated history of bamboo slips and slips in ancient times, and greatly promoted the spread and development of culture. Paper is the accumulation of long-term experience and wisdom of the working people of the Han nationality. It is a sheet-like fiber product used for writing, printing, painting or packaging. [0003] The production of general printing paper is divided into two basic processes of pulping and papermaking. Pulping is to use mechanical methods, chemical methods or a combination of both to dissociate plant fiber raw materials into natural pulp or blea...
