Description

Oil and water treatment device

The present invention relates to oil and water treatment devices.

Whether industrial wastewater or household wastewater is often a mixture of oil and water, it can easily cause pollution if it is directly discharged into the environment, especially the oil-water mixture containing metal shavings from factories. Therefore, the oil-water mixture usually needs to go through a separation operation to separate the oil body from the non-oil body (such as water) as much as possible.

A common method of oil-water separation is through an oil-water separation tank. Using the difference in specific gravity, the oil body will float above the water to form an oil layer. The separation operation is further carried out by sucking the oil body above or discharging the liquid below. However, the method of directly introducing the oil-water mixture into the oil-water separation tank may cause the impurities in the oil-water mixture to clog the holes of the oil-water separation tank, thereby causing the flow to be sluggish and the separation efficiency to be low.

Another way to separate oil and water is to use an oil scraper, which uses the characteristic that the viscosity of oil is greater than the viscosity of water. It uses a turntable or chain to stick the oil and take it away from the water to achieve the purpose of oil-water separation. However, the cost of this type of oil scraper is relatively expensive, and the oil body is easy to accumulate on the scraper, resulting in low separation efficiency.

Therefore, it is necessary to provide a novel and progressive oil and water treatment device to solve the above problems.

The main purpose of the present invention is to provide an oil-water treatment device that can effectively and quickly scoop out oil-water mixture to assist and improve the efficiency of oil-water separation from the oil-water mixture.

In order to achieve the above object, the present invention provides an oil and water treatment device, including: a power unit, a transport unit and at least one scooping piece. The transport unit is a disk. The transport unit is connected to the power unit and driven by it. The transport unit is partially immersed in an oil-water mixture in a tank. The area where the transport unit is immersed in the oil-water mixture is defined as A scooping area, the area where the transport unit is not immersed in the oil-water mixture is defined as a moving area; the at least one scooping piece is positioned on the disc body and can move cyclically between the scooping area and the moving area, The at least one scooping piece includes a communicating scooping opening and an accommodating space. In the radial direction of the disc body, the accommodating space is located within the circumferential range of the disc body; wherein, when the at least one scooping piece When a scooping piece moves to the scooping area, part of the oil-water mixture enters the accommodation space through the scooping opening for storage, and then when the at least one scooping piece moves toward the moving area with the disk, , the at least one scooping piece takes away the scooped oil-water mixture away from the container.
