Problems solved by technology
[0002] At present, many industries are facing the problem of oil-water separation. For example, various oils used in oil fields and oil-water separation in sewage sedimentation tanks are mostly used to manually remove oil slicks, which is time-consuming, laborious and dangerous. Another example is catering. The oil-water separation in the garbage disposal process adopts a fixed liquid surface oil-water separation. The above separation methods have limitations in application, that is, they are not suitable for oil-water separation under fluctuating liquid surface conditions.

Embodiment Construction
[0007] In the figure, a float (9) and a guide rail (7) are installed in the oil-water mixing reservoir (10), the guide rail (7) is fixed on the guide rail fixing frame (8), and the float (9) is under the control of the guide rail (7) Floating up and down, the oil inlet adjustment threaded cock (6) is installed on the float (9), the float (9) is connected with the oil collecting tank (2) through the float connecting hose (4), and the oil collecting tank (2) is equipped with an oil discharge pump (3), when the oil-water mixed liquid enters the oil-water mixed liquid storage tank (10), the oil-water mixed liquid is separated by gravity, and the residual oil floats on the liquid surface to form a residual oil layer (5), and the residual oil passes through the oil inlet adjustment screw cock (6) flows into the float (9), and flows into the oil sump (2) through the float communication hose (4) communicated with the oil sump (2), and finally discharged by the oil discharge pump (3).

The invention provides a separation method of a float-type oil-water separator. A float and a guide rail are installed in an oil-water mixed liquid storage tank, the float floats up and down under thecontrol of the guide rail with a fluctuation liquid surface, an oil inlet adjusting threaded cock is installed on the float, so that an oil inlet interface is adjusted; and an oil-water mixed liquidcommunicates with an oil collection tank through a float communication hose, and an oil discharge pump is installed in the oil collection tank. According to the method provided by the invention, whenthe oil-water mixed liquid flows into the oil-water mixed liquid storage tank, under the action of gravity separation, residual oil floats on the water surface to form a residual-oil layer, and the residual oil firstly enters the oil inlet adjusting threaded cock installed on the float and then flows into the oil collection tank through the float communication hose and finally is discharged by theoil discharge pump.
Description
technical field [0001] The invention relates to a separation method of a float type oil-water separator, which has a good oil-water separation effect especially for fluctuating liquid levels. Background technique [0002] At present, many industries are facing the problem of oil-water separation. For example, various oils used in oil fields and oil-water separation in sewage sedimentation tanks are mostly used to manually remove oil slicks, which is time-consuming, laborious and dangerous. Another example is catering. The oil-water separation in the waste treatment process adopts fixed liquid surface oil-water separation. The above separation methods have application limitations, that is, they are not suitable for oil-water separation under fluctuating liquid surface conditions. Contents of the invention [0003] In order to solve the above problems, the present invention provides a float type oil-water separator separation method. The technical solution adopted in the pre...
