Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, in particular to an oil-water separator for ship sewage treatment. Background Technique

[0002] An oil-water separator is a device used to separate oil pollutants in liquids, and is widely used in the fields of industry, transportation and environmental protection. Its basic function is to effectively remove the oil content in the oily wastewater to reduce environmental pollution and protect water resources.

[0003] Common oil-water separators generally use an inlet pipe to guide the oily water mixture to be treated into the device, separate the oily water mixture through a separation barrel, use an outlet pipe to discharge the clean water, and discharge the separated oil through a drain pipe.

[0004] However, since the oil-water separation is based on the principle of gravity separation, the oil molecules rise to the water surface and are discharged through the oil collection area. After the oil is discharged, there will still be oil remaining in the part where the oil contacts the water surface. When the water is discharged, the remaining oil will also be discharged, resulting in poor oil-water separation effect. Content of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides an oil-water separator for ship sewage treatment to solve the problem that after the oil is discharged, there is still oil remaining in the part where the oil contacts the water surface, and when the water is discharged, the remaining oil will also be discharged, resulting in poor oil-water separation effect as mentioned in the above background technique.

[0007] (II) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solution: An oil-water separator for ship sewage treatment, comprising:

[0009] A base, on the upper surface of which an installation frame is installed;

[0010] A separation barrel, arranged on the upper surface of the base, with a drain pipe installed on the upper left side of the separation barrel and an outlet pipe installed on the lower right side of the separation barrel;

[0011] A driving machine, arranged on the lower surface of the top plate of the installation frame, the rotor of the driving machine is coaxially installed with a driving rod, and a fixing plate is screwed on the surface of the driving rod;

[0012] An installation seat, arranged at the bottom of the fixing plate, and a cleaning sponge is installed at the bottom of the installation seat.

[0013] Preferably, a motor is installed at the bottom of the separation barrel. The rotor of the motor coaxially penetrates through the bottom of the separation barrel and is installed with a rotating rod. Stirring rods are evenly installed on the surface of the rotating rod. Starting the motor can drive the rotating rod to rotate, thereby driving the stirring rods to rotate, preventing the oil droplets from emulsifying and promoting the separation of oil.

[0014] Preferably, valves are installed on the surfaces of both the drain pipe and the water outlet pipe. The cleaning sponge is adhesively bonded to the bottom of the mounting seat. Opening the valves can drain the oil through the drain pipe and drain the water through the water outlet pipe.

[0015] Preferably, threaded holes are opened at the four corners of the upper surface of the base. Positioning rods are screwed into the threaded holes of the base. The base can be fixed through the positioning rods, improving the stability of the device.

[0016] Preferably, sliding rails are welded to both sides of the lower surface of the top plate of the mounting frame. Sliders are installed on both sides of the fixing plate. The sliders are embedded in the inner cavities of the sliding rails. The sliders and the sliding rails enable the fixing plate to move vertically.

[0017] Preferably, fixing rods are evenly installed at the bottom of the fixing plate. The bottom ends of the fixing rods are connected to the upper surface of the mounting seat, enabling the mounting seat to rise and fall with the fixing plate.

[0018] Beneficial effects

[0019] Compared with the prior art, the present utility model provides an oil-water separator for ship sewage treatment, having the following beneficial effects:

[0020] This oil-water separator for ship sewage treatment uses a separation barrel to separate oil and water by gravity. The heavier water sinks, while the lighter oil floats. The separated oil can be drained through the drain pipe. Starting the drive motor can drive the drive rod to rotate, thereby driving the fixing plate to rise and fall, and further driving the mounting seat to move downward and extend into the inner cavity of the separation barrel, bringing the cleaning sponge into contact with the upper surface of the water. Since the density of oil is less than that of water, it will float on the upper surface of the water body, enabling the cleaning sponge to absorb the oil remaining on the water surface, preventing oil from remaining in the discharged water body and improving the effect of oil-water separation.
