我厂的乳化液系统现有的二手刮板式撇污装置从5.19使用至今,发现在乳化液槽液面上漂浮着很厚的一层粘稠的沥青状污染物,难以满足生产工艺的要求,问题主要存在于以下两个方面:(1)由于液位不能总保持在高位,此时固定的刮板就不能刮到污物,而且刮板走行速度过低;另外因为刮板必须是软性材料才能贴紧槽内隔板,但由于橡胶刮板长时间浸泡在温热的乳化液中会变形,最终导致失效。(2)乳化液槽结构设计得不合理,导致
The existing second-hand scraping scraping device of the emulsion system of our factory has been used from 5.19 up till now, and found that a thick layer of viscous bituminous pollutant floats on the liquid surface of the emulsion tank, which is difficult to meet the requirements of the production process. The problem mainly exists in the following two aspects: (1) As the liquid level can not always remain high, then the fixed scraper can not scratch the dirt, and the scraper travel speed is too low; the other because the scraper must be soft The material can be pressed against the partition, but the rubber scraper will deform in the warm emulsion for a long time so as to eventually fail. (2) emulsion tank design is not reasonable, resulting
