Neutralization reaction tank for oil refining

The invention discloses a neutralization reaction tank for oil refining, and relates to the technical field of oil refining, in particular to a top cover and a discharging port, a tank body is arranged at the lower end of the top cover, a fixing disc is installed on the outer surface of the tank body, a connecting disc is arranged at the lower end of the fixing disc, and a supporting frame is arranged at the lower end of the connecting disc; and a fixing plate is mounted on the outer side surface of the supporting frame. According to the neutralization reaction tank for grease refining, through interaction of a rotating shaft and a servo motor, assemblies, connected with a first hydraulic air rod, on a connecting disc can synchronously rotate, through rotation of a barrel body, a cleaning brush can be driven to synchronously rotate outside a discharging opening, and the cleaning efficiency of the discharging opening can be effectively improved; and when the discharging opening does not need to be cleaned, a c
