AI Technical Summary
Existing building water supply and drainage collection devices allow hair and other debris to enter the sewage pipes through floor drains, resulting in poor filtration and an inability to effectively remove oil from sewage, leading to pipe blockage.
A collection device including a water seal structure, a collection pipe and a drain pipe is designed. Wastewater is collected through the collection pipe to a filter screen inside the water seal structure for secondary filtration. The water seal structure is equipped with an inverted L-shaped partition to divide it into a filtration chamber and a drain chamber. The filter screen is installed on the frame and is removable. It is equipped with a sealed top cover and an observation window. An oil collection trough and an oil scraper are provided under the filter screen for separate collection of floating oil.
It improves filtration efficiency, prevents gas from entering the room, avoids sewage overflow, and allows for timely replacement or cleaning of the filter screen to prevent grease from clogging the pipes. It is suitable for oily wastewater from the kitchen.
