Improvement On The Process And Equipment Of Obsolescence Corrugated Cardboard Mass Pulping Production

Obsolescence Corrugated Cardboard(OCC)prices continue to rise,and its quality are also continued to deteriorate,in order to solve due to the decrease of the quality of the waste corrugated paper bring problems to the production,people into production equipment unceasingly,makes waste corrugated paper processing process increasingly tend to be complicated,to increase investment,energy,production cost,bring a lot of pressure to waste corrugated paper pulping industry.Therefore,for the waste corrugated paper processing technology,people expect to get more compact,more perfect and high yield of technology and equipment.Analyzed the mass production of high yield pulping obsolescence corrugated paper production technology and equipment,as well as the problems of OCC pulping process line,and put forward the domestic OCC pulp and other pulping line slag mixed in certain proportion as the concept of raw materials,analyses the basic design parameters of corrugated paper,obsolescence corrugated paper pulping production line of the main technological process,water balance,every pulp system and the key technology and main production line of debugging test,the feasibility of the whole OCC pulp production line was verified through the final production debugging.Aiming at high production efficiency,the concept of discharging heavy slag at the bottom of the screening equipment in the pulping production line was put forward,and the up-flow pressure screen was analyzed and planned,which effectively prevented the heavy impurities from entering the screening area,realized the high production and prevented the damage of the larger impurities to the screening equipment,and increased the service life of the equipment.In view of the breaking circuit in the process,the process parameters of pulp in the breaking process are analyzed and analyzed.The concept of optimizing the pulping process of waste paper was put forward to improve the production efficiency.In view of the existing waste paper pulping production line of its recommendations and to plan,through the method of combining theory and practice based on technical requirements and pulping equipment manufacturer of many years of experience in planning,put forward the programming and four positive slag separator group with two light slag separator with the use of concept,implements the discharge rate of ascension and the reducing of the fiber losses,eventually the pulping production line of pulp rate as high as ninety percent.
