【技术实现步骤摘要】
罐车刷洗密封盖本专利申请案主张申请号为“201720537672.5”、名称为“罐车刷洗密封盖”、申请日为“2017.05.14”的中国技术专利申请的优先权。
本技术涉及油品运输装置领域,具体涉及一种罐车刷洗密封盖。
技术介绍
我国轻质油品及化工品的运输主要是以铁路油罐车为运载工具,罐车装车前通常要进行清洗作业,而清洗过程需要进行蒸汽蒸煮、吹风干燥等环节。而这些作业环节是在敞口的情况下进行,部分有毒有害气体会挥发到大气中,为避免这种现象,需要在清洗过程中对车口密闭、气体收集处理。罐车刷洗密封盖就是为了实现这个过程的密封作业。现有技术中通常采用敞口作业,蒸煮、吹风干燥过程有害气体外溢。
技术实现思路
本技术提供一种罐车刷洗密封盖,可实现在密封条件下完成罐车的高温清洗与干燥过程。本技术采用的技术方案为:一种罐车刷洗密封盖,包括盖体、密封装置与清洗装置;所述盖体设置盖体上腔、盖体下部与清洗通道,盖体上腔设置在盖体下部上方,且盖体上腔与盖体下部均环绕清洗通道设置,盖体上腔与盖体下部通过泄气道连通,所述泄气道设置控制阀,盖体设置进气口和排气口,进气口与清洗通道连接,排气口与盖体上腔连接;清洗装置设置在清洗通道内,包括污水管线与蒸汽管线。罐车完成清洗后,关闭泄气道,通过进气口进入的空气将污水或气体经清洗通道排出,排出完成后打开泄气道,进气口进入的空气经清洗装置、盖体下部、盖体上腔与排气口排出,完成干燥过程。优选的,所述泄气道环绕清洗通道设置,控制阀为密封盘,密封盘设置在泄气道下方,所述密封盘设置控制手柄。泄气道环形设置可保证气体流通更加均匀。优选的,所述清洗装置还包括套体,污 ...
