Abstract

The present invention relates to a manhole having a see-through window. The purpose of the present invention is to check the status of gathering of waste oil lumps and alien substances inside the manhole by the naked eye through the see-through window of the cover of the manhole such that timely collection and cleaning can be conducted, and to enable convenient use thereof at places with less generation of wastewater that contains oil, such as a detached house, a multiplex house, a parking lot, a gas station, and a road. The present invention provides a manhole comprising: a manhole body having a wastewater inflow tube and a domestic sewage discharge tube; and a cover fitted onto the manhole body, wherein a see-through window is provided in the cover fitted onto the manhole body. The present invention described above has the following advantages: when wastewater that contains oil flows into the manhole, oil and sewage are gravity-separated; gas and odor generated by decay of the oil and sewage inside the manhole are discharged together with the sewage through the discharge tube; the lumps of oil gathered in the manhole grow and generate buoyancy; when the generated buoyancy lifts a floating member, the manager can check the same by the naked eye through a see-through lens of the see-through window; and the oil lump and alien substances can be timely collected and cleaned off, thereby ensuring a convenient use.

Description

Manhole with sight glass

The present invention relates to a manhole provided with a see-through window, and is provided with a see-through window on the cover of the manhole to simplify collection and cleaning.

In the case of industrial sites where large amounts of waste oil (oil) and sewage are generated in a large and constant manner, waste oil and sewage are separated and treated in various ways, such as specific gravity separation method, hydraulic separation method, and adsorptive separation method, depending on the generation amount, frequency, and type of running water. Doing.

However, the amount of sewage generated from single-family homes, multi-family houses, roads, parking lots, gas stations, restaurants, etc. It is unspecified and low in quantity, so it cannot be separated and flowed into the manhole with mixed oil and domestic sewage, and only foreign substances are filtered out and discharged to the wastewater treatment plant through the sewage pipe.

In the above process, when the viscosity is higher than the living sewage and cooled, the oil solidifies into agglomerates with foreign substances and is adsorbed to the inner wall of the pipeline in the process of passing through the manhole and sewage pipe, and the pipeline is narrowed and blocked. Pumps that transfer them are loaded with viscous oil, causing mechanical failures, and purifying the sewage containing oil is a factor that reduces purification efficiency.

As a means of solving this, install an oil separation chamber in the manhole to separate oil and water, collect the oil in the oil storage tank at the bottom of the manhole, discharge it to the outside, and use the manhole configured to discharge living sewage from the manhole to the sewer pipe, Oil and domestic sewage flow into the manhole, and the domestic sewage is discharged into the discharge pipe, and the oil with low specific gravity is used to be configured to be raised and collected on the domestic sewage and to be discharged from the central cleaning pit.

Such a conventional means is difficult to check the collected foreign matter and injured oil mass with the naked eye, and when the collection time of the foreign matter and oil is missed, there is a drawback that the sewer pipe is blocked by the oil mass.
