摘要

2. Improve the liquid storage tank and use a more effective way to accumulate undesirable materials from the bottom of the tank. A cylindrical tank consists of a bottom or sink, with its center position lower than the edge level, where waste is concentrated. From this center, drain the slide type water ski with slide plate or side plate, bring the bad material to the edge of the tank, and then discharge it through the drain pipe or other drainage system.
