【摘要】：从渗透现象的发现到反渗透膜片的成功应用至今已有近200年的历史,但从历史的长河中看该技术仍属于个新兴行业范畴,以反渗透膜法的海水淡化技术具有极其广阔的发展空间。基于Rochem公司开发的盘管式模柱(DTRO)的独特结构设计及先进的系统控制极大地提高了过滤元件的使用效率及使用寿命,在海水淡化及垃圾处理行业中凸显其重要价值,从行业的发展趋势看,膜法海水淡化技术在未来仍会占据主导地位。本文根据盘管式模柱的工艺特点,结合目前业内膜片的加工方式及模柱的组装方式,提出了对膜片加工及模柱组装的自动化装备的研发方案,在膜片的加工装备设计中,创新采用多套分度系统与超声波焊接系统相结合,攻克解决了过滤膜片切割焊接工艺设备中的关键技术难点,研制成功全套自动化加工设备。本文研制的新设备可以实现焊接及切割同步,焊接及切割后工位的自动更换,原料及成品的自动化抓取等。相比传统膜片加工设备,新型加工设备可大幅降低外界人为因素对产品品质的影响,显著提高加工效率及产品的成品率。设备测试结果表明,单片成型周期由180s提高至24s,效率提高了7.5倍；生产线成品合格率由80%显著增至99%以上；同时,对模柱组装的压缩锁紧工序的装备研制,对提高模柱装配的质量起到了决定性意义,伴随设备自动化程度的提高,极大地节省了人工成本并降低了劳动强度。本文研究成果已实现规模化生产,并成为盘管式模柱膜片加工及模柱装配的主体加工设备,具有十分重要的工业应用价值。
[Abstract]:From the penetration phenomenon found successful application of reverse osmosis membrane has been nearly 200 years of history, but from the history of the technology still belongs to a new industry category, in the reverse osmosis membrane desalination technology has the extremely broad space for development. The coil type die column Rochem developed based on DTRO (the unique design of the structure) and advanced control system can greatly improve the efficiency and service life of the filter element, highlights its important value in seawater desalination and waste disposal industry, from the industry's development trend, membrane desalination technology in the future will still occupy the dominant position. According to the process characteristics of coil type die column, combined with the current processing industry and the film mode column assembly way, put forward assembly on the membrane processing and die column automation equipment R & D project, in the design of the processing equipments of a diaphragm, innovation The set of index system and ultrasonic welding system combining solving filtration film cutting key welding equipment, full automatic processing equipment was developed successfully. The new equipment developed in this paper can realize synchronous welding and cutting, welding and automatic replacement after cutting station, raw materials and finished products automatic grabbing etc. compared with the traditional film processing equipment, new processing equipment can greatly reduce the influence of artificial factors on the product quality, improve processing efficiency and product yield. Equipment test results show that the monolithic molding cycle increased from 180s to 24s, the efficiency is increased by 7.5 times; production line yield by 80% significantly increased to more than 99%; at the same time the mold assembly, column compression locking process equipment development, the decisive significance to improve the quality of the mold assembly column, with the degree of automation equipment It has greatly saved labor costs and reduced labor intensity. This research achievement has been realized in large-scale production, and has become the main processing equipment of coil die diaphragm machining and die column assembly. It has very important industrial application value.
