| The red as well calls red mire and refines the industrial solid discard of oxidizing the aluminum rear row from the aluminum soil the mineral.Generally contain to oxidize iron to have great capacity, the external appearance is similar to red mud, as a result get.Red mud percolation is mix allied method production to oxidize to do obeisance an Er method in the aluminum with burn knot method to connect up properly of important link.This text Chien said branch in Chinese aluminum industry, Shandong to oxidize the aluminum red mire to filter craft process and pointed out the key equipments in the process-turn the drum percolation machine existent problem.Along with oxidize the significant increment of aluminum yield, the production ability which filters machine has been obviously not enough, and have become a serious check and supervision to oxidize aluminum to lift to produce of bottleneck link.Filter the work preface actual need according to the red mire, this thesis with 100 m2s turn drum percolation machine for research object, pass theories analysis, built up to turn the mathematics model that the drum filters machine, put forward a new design project, do to turn drum percolation the virtual kind machine of the machine, make a physical kind machine to apply in produce.The thesis concretely openned an exhibition a thorough research in several following aspects:1.The thesis analysis introduced domestic and international filter technical development trend, especially the vacuum filter a technique.Its structure is simple and cover area small, the processing have great capacity, the price is low and maintain workload small.The point was analytical to relatively to turn the characteristics, application and characteristic etc. that the drum vacuum filters machine.2.The vacuum percolation belongs to constant pressure percolation, this text according to think to the Lu of constant pressure filter equational analysis, material property and percolation which influence vacuum to sign dish percolation machine to filter the main factor of the efficiency and the vacuum of the system, filter time, filter area and filter a liquid lie quality to contain very great relation.3.Pass to turn drum percolation to the domestic and international market existing vacuum machine and carry on a survey and discovered the problem of existence. Aim at analysis and survey, turn to aim at these impact factors in the design of drum percolation machine in the vacuum, improve a design to filter an efficiency by exaltation respectively. Exist to filter drum in the manufacturing of rigid worse, easily the occurrence transform of phenomenon, and not repair, filter drum for the sake of the exaltation of rigid, filter a drum frame to design into mesh structure. For the sake of exaltation system of vacuum, adopt measure decrease to the related conjunction part the vacuum reveal and weld structure towards moving allotment valve adoption, the aggrandizement filters liquid tube diameter and lets up to filter liquid tube length, is filtering the pressure loss of passage while canning reduce filter. The space grid that passes to improve filtering of design room structure and improvement design solved to filter a liquid to remain a problem, and canned conveniently and alone replace space grid.Drive the way adoption asunder drives, then filter drum, mix blend and unload to anticipate to independently drive respectively, control software to carry out catena through a work, convenience credibility. For making to filter a round flat cake to get full rinse, improved to wash away dirt device, made to wash away dirt water to get fog to turn, distribute even.4.Make use of from the design method of crest but bottom, carry on parameter to turn a design towards turning drum percolation machine, created to turn drum percolation the virtual kind machine of the machine, lay solid foundation for the later new product development.Through improvement and design, vacuum rotary drum filters machine is getting more reasonable and filter an efficiency higher.
