Description

TECHNICAL FIELD

[0004] 1: Although the ton barrel has a discharge port at the lower side, it can directly discharge or be connected with the pipe opening to make the liquid raw material in the ton barrel automatically flow out and discharge under the action of gravity, but the ton barrel needs to be lifted so that the discharge port is higher than the inlet of the treatment pool or the storage tank, and when a large number of ton barrels are stacked together, it is also difficult to unload, and workers need to use forklifts to transfer the ton barrels one by one to the appropriate position, which consumes manpower and resources;

[0005] 2: If a material suction pipe is inserted into the ton barrel from the upper opening of the ton barrel, the liquid raw material is sucked out by the suction force of the pump, which can reduce the work intensity of the workers and improve the discharging efficiency, but the pipe opening of the traditional material suction pipe is flat, and when it is inserted into the ton barrel, the pipe opening of the material suction pipe will be attached to the bottom surface of the ton barrel, and as the material suction is gradually formed, the material suction pipe is sucked to the bottom surface of the ton barrel, which causes the material suction pipe to be unable to normally suck the material;

[0006] 3: In order to solve the problem of the ton barrel being sucked by the material suction pipe due to the vacuum adsorption of the ton barrel, the material suction pipe needs to be held by hand when it is inserted into the ton barrel, and the material suction pipe needs to be held to avoid being sucked, which can cause the liquid raw material in the ton barrel to be not completely sucked, and the pipeline part can also cause backflow, which consumes labor.
