Tank type container

ActiveCN101301952AImprove the forceOptimize usage efficiencyLarge containersStress conditionsEngineering
The invention relates to a tank-shaped container, comprising a tank body, a reinforcing ring arranged on the outer side of the tank body and a bottom discharging valve arranged below one end of the tank body. A manhole, a safety valve, an air-phase valve, a top discharging hole and an overflowing box are arranged on the top of the tank body. An overflowing tube used for guiding liquid in the overflowing box to the outside of the tank-shaped container is arranged at the bottom of the overflowing box. The two ends of the tank body are respectively welded onto the end frames of the two ends by apron rings, and the end frames of the two ends are respectively connected with a vertical bottom beam and a reinforcing inclined support. A stair fixedly arranged on the end frame of one end is led to a path board fixedly arranged on the top of the tank-shaped container. An angle part, an angle column, a top beam, a bottom beam, the reinforcing inclined support and a top angle board are connected to form the end frame. A reinforcing plate is welded on the internal surface of the lower wall of a rectangular tube of the bottom beam. The tank-shaped container has the main advantages that the distance between the lower surface of the end part of the bottom beam of the end frame and the lower surface of the angle part of the end frame is enlarged, therefore, the stressing condition of the bottom beam of the end frame during conveying is enhanced and the service efficiency of the tank-shaped container is improved.
