刮刀式自清洗过滤器刮刀机构的设计

Design on Scraper Facility Used in the New Type Self-cleaning Filters with Scraper

刮刀式自清洗过滤器是一种新型的过滤设备,其关键部件是刮刀机构,而目前市场上现有的刮刀机构往往难于彻底清污,针对刮刀机构的这一缺陷,应广州某化工厂的要求,在分析了国内外许多刮刀机构结构的基础下,联合开发了新型刮刀机构,工作过程中保证刮刀机构始终与滤网接触,能有效彻底地清除沉积在滤网上的杂物,通过用户使用证明,使用效果良好。文中介绍了刮刀式自清洗过滤器的工作原理、刮刀机构的结构和设计方法。

The type of self-cleaning filters with scraper is a new type of filtering equipment and its key part is scraper facility.And now most of the scraper facilities are difficult to remove sundries existed at market.Aimed at the defects,the scraper facility was developed to satisfy the customer demand of Guangzhou the requirements of a chemical plant based on the analysis of the domestic and foreign many structure of Scraper facility.During work process the scraper facilities always contacts with strainer,this can remove particles thoroughly deposited in the strainer.Use effect is good through the use.According to identify by department of henan science and technology,it achieved the domestic leading level.The paper introduced the working principle of the New Type Self-cleaning Filters with Scraper,the structure and design procedures of scraper facility.
