| With the rapid development of China’s economy and science and technology,people’s living standards have been continuously improved.The ever-increasing demands for the quality of the living environment and the increasingly serious industrial pollution have created irreconcilable contradictions.To this end,the state has continuously strengthened the efforts to rectify industrial pollution,and invested a large amount of funds and manpower to comprehensively control the industrial "three wastes" waste gas,waste liquid and solid waste.As an important condition guarantee for colleges and universities and research institutes,the laboratory also supports the development of teaching and research undertakings,and the waste generated in the work of experimental equipment also has an impact on the environment.Among them,the treatment of waste oil from experimental equipment is one of the problems to be solved urgently.The subject is aimed at the practical problems of difficult recovery of waste oil from laboratory equipment and environmental pollution.The research and development of automatic oil purification treatment equipment for experimental equipment is carried out by using ultracentrifugation technology,hydraulic transmission technology and automatic control technology.Mobile oil purification equipment.Focus on the research and design of the purification method,mechanical structure,control system and waste oil collection method of the equipment,and provide a solution for the recovery and reuse of the experimental equipment oil.Firstly,based on the in-depth analysis of current domestic and international oil purification treatment technologies,the oil purification method based on ultracentrifugation technology is discussed.From the aspects of oil purification process,control means and methods,operation and application,the overall scheme of the experimental oil automatic purification treatment device is conceived and designed,and the oil automatic purification treatment system of the experimental equipment is constructed.Secondly,through the analysis of equipment control requirements,the requirements of equipment in the control system software are clarified.Then,the whole purification process is analyzed in detail,and the principle of equipment control and the overall control scheme of equipment are determined.On this basis,a reasonable control process is designed.Finally,the programming and human interaction interface are combined to design the control system software to realize the automation and intelligent operation of the whole deviceThirdly,based on the analysis of equipment hardware,the overall scheme of the mobile oil automatic purification processing system hardware was developed.The hydraulic system and control system hardware of the equipment are analyzed separately,and the unique purification hydraulic circuit and the complete hardware control system principle are designed.The combination of the two functions realizes the related functions of the oil purification treatment of the equipment.Finally,through the analysis and calculation of the expected function and processing capacity of the equipment,the components of the hydraulic and control system system were selected.Finally,the prototype of the equipment is manufactured on the basis of the design,and the design is continuously improved during the manufacturing assembly process.The test experiment of the oil treatment process is carried out on the completed prototype,and the experimental results are recorded and studied.The equipment is analyzed by verifying the on-off state of the relevant components and the oil purification condition,and verifying the experimental equipment oil.The feasibility of purifying the treatment system. |
