Novel bell jar type oil tank wall structure

The utility model discloses a novel bell jar type oil tank wall structure, comprising a front wall, a rear wall, a side wall A and a side wall B; the front wall is respectively aligned and connected with the edge at one side of the side wall A and the side wall B; the rear wall is respectively aligned and connected with the edge at the other side of the side wall A and the side wall B; the front wall, the rear wall, the side wall A and the side wall B are all made of a steel plate and are bent to form a bent part respectively. The steel plates are bent to form the bent parts integrated with an oil tank wall, and the bent parts replace reinforced ribs welded at the outside of the oil tank wall, so the heavy workload of welding the reinforced ribs is effectively avoided, and the strength use needs of an oil tank are met; the bent parts with the action of the reinforced ribs are integrally made with the tank wall, so the integrity and attraction of the oil tank wall are further improved.
