Continuous pipeline oxidation equipment and process for preparing nitrobenzoic acid

The invention discloses continuous pipeline oxidation equipment and process for preparing nitrobenzoic acid, and relates to the technical field of nitrobenzoic acid preparation equipment. According to the continuous pipeline oxidation equipment and process for preparing nitrobenzoic acid, by arranging the synchronous driving mechanism, after materials are fed and put into the inner side of the reaction kettle, stirring work is carried out, meanwhile, a sealing cover can press and seal a feeding opening, it can be guaranteed that the sealing cover always covers the feeding opening in the stirring process, and therefore the continuous pipeline oxidation equipment and process have the advantages of being simple in structure and convenient to use. The feeding port can be automatically opened after stirring is finished, automation of opening and closing of the sealing cover and synchronization of the sealing cover and the stirring assembly are achieved, independent manual operation is not needed, and timeliness of
