Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.

Oil water enters the sundry separating box (2) from the water inlet (1), sundries are separated through the filter screen (5), the oil water after sundries separation enters the oil water separating box through the communicating pipeline (4), and the aeration device (9) at the bottom of the oil water separating box continuously releases bubbles to promote the separation of the oil water. The separated oil is discharged through an oil discharge valve (13), and the heating device (11) and the temperature sensor (12) in the oil collecting area prevent the oil from being condensed when the temperature is low. Separated water enters a water collecting tank through a communicating pipeline (15), when the liquid level in the water collecting tank rises to a low liquid level position set by a liquid level switch, a liquid level signal is fed back to an electric cabinet (21) through a signal line (27), the electric cabinet automatically controls one sewage pump to start for draining, when the drainage of one sewage pump cannot meet the requirement, the liquid level rises to the liquid level set by the liquid level switch and the liquid level of two sewage pumps needs to be started, the liquid level signal is fed back to the electric cabinet (21) through the signal line (27), the electric cabinet automatically controls the other sewage pump to start for draining, when the liquid level rises to a set alarm liquid level, the liquid level signal is fed back to the electric cabinet (21) through the signal line (27), the electric cabinet gives an alarm, and informs personnel of handling abnormity; on the contrary, when the liquid level drops below the set alarm liquid level, the electric cabinet automatically relieves the alarm, when the liquid level drops below the liquid level which is set by the liquid level switch and needs to start the two sewage pumps, the electric cabinet automatically controls to reduce the operation of one sewage pump, and when the liquid level drops below the low liquid level which is set by the liquid level switch, the electric cabinet automatically controls to reduce the operation of one sewage pump. And the electric cabinet has the functions of controlling the sewage pump to start and stop first and to alternate with each other, so that the service life of the water pump is effectively ensured.

Alternatively, the sewage pump can be one or a plurality of sewage pumps.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
