[0001] The utility model relates to the technical field of oil-water separators, and particularly relates to a combined oil-water separator. Background Art

[0002] An oil-water separator is a device specifically designed to effectively separate oil and water. Its working principle is mainly based on the density difference between oil and water. By using the method of gravity sedimentation, this device can effectively remove impurities and moisture in the mixed liquid. Just like all mechanical equipment, the oil-water separator also requires regular maintenance and cleaning work. After running for a period of time, if it is not cleaned regularly, a large amount of grease and other residues will accumulate on the inner wall of the oil-water separator, which will not only affect the separation efficiency of the device, but also reduce the overall service life of the oil-water separator device.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment, please refer to Figures 1-3 , the present utility model provides a technical solution:

[0021] A combined oil-water separator includes a mounting bracket 1. A heat insulation housing 2 is installed on the outer wall of the mounting bracket 1. A heating tube 3 is provided on the inner wall of the heat insulation housing 2. A separator housing 4 is provided on the inner wall of the heat insulation housing 2. A cleaning assembly 5 is installed at the port of the separator housing 4. A sieve frame housing 6 is provided on the inner wall of the separator housing 4, and sieve holes 7 are evenly formed on the outer wall of the sieve frame housing 6. A partition 8 is provided on the inner wall of the separator housing 4. An oil outlet pipe 9 is installed on the outer wall of the separator housing 4. A liquid outlet pipe 10 is installed on the outer wall of the separator housing 4. A sewage discharge pipe 11 is installed on the outer wall of the separator housing 4 on one side of the liquid outlet pipe 10;

[0022] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3, the cleaning assembly 5 includes an upper cover 501 which is installed at the port of the separator housing 4. A water storage housing 502 is installed on the outer wall of the upper cover 501. A controller 503 is installed on the side wall of the water storage housing 502. An electric control water pump 504 is installed on the outer wall of the water storage housing 502. The liquid outlet of the electric control water pump 504 is connected to a conduit 505. One end of the conduit 505 penetrates through the upper cover 501 and extends to the inner wall of the upper cover 501 where an electric control pressurized spray head 506 is installed. There are multiple groups of electric control pressurized spray heads 506 which are respectively located on the outer wall of the conduit 505. The liquid inlet pipe 507 is located on one side of the conduit 505. The liquid inlet pipe 507 is installed on the outer wall of the upper cover 501. One end of the liquid inlet pipe 507 penetrates through the upper cover 501 and extends into the inner cavity of the upper cover 501.

[0023] Furthermore, the heating pipe 3 is located between the heat insulation housing 2 and the separator housing 4. When the controller 503 is electrically connected to the heating pipe 3, the electric control pressurized spray head 506 and the electric control water pump 504 through wires, the device is powered on. The mounting bracket 1 is of a frame structure. The screen frame housing 6 is located directly below the liquid inlet pipe 507. There are multiple groups of partitions 8 which are respectively located on the opposite inner walls of the separator housing 4. The partitions 8 sequentially divide the inner cavity of the separator housing 4 into a liquid inlet cavity, a separation and precipitation cavity, and a liquid outlet cavity. The screen frame housing 6 is located inside the liquid inlet cavity. The oil outlet pipe 9 is located inside the separation and precipitation cavity. The liquid outlet pipe 10 and the sewage discharge pipe 11 are both located inside the liquid outlet cavity. The sewage discharge pipe 11 is located at the bottom of the separator housing 4. The liquid outlet pipe 10 is located above the sewage discharge pipe 11 and the liquid outlet pipe 10 is located on one side of the partition 8.

[0024] Furthermore, when the oil and grease mixed liquid flows into the liquid inlet cavity through the liquid inlet pipe 507, large particles of debris are intercepted by the screen frame housing 6, and the liquid flows into the liquid inlet cavity. Subsequently, the liquid flows into the separation and precipitation cavity through the through groove below the partition 8 for precipitation. The oil and grease floats on the upper part of the liquid and flows out through the oil outlet pipe 9. At the same time, the liquid flows into the liquid outlet cavity through the through groove below the partition 8. The clean liquid above is also intercepted by the partition 8 on one side of the liquid outlet pipe 10, and the clean liquid flows out through the liquid outlet pipe 10.

[0025] Working process of the utility model: When the combined oil-water separator designed by this solution is in operation, hot water is stored in the inner cavity of the water storage housing 502. Under the action that the controller 503 is electrically connected to the heating pipe 3, the electronically controlled pressurized spray head 506 and the electronically controlled water pump 504 through wires respectively, the switch of the controller 503 is turned on to energize the device. An electronically controlled water pump 504 is installed on the outer wall of the water storage housing 502. The liquid outlet of the electronically controlled water pump 504 is connected to a conduit 505. One end of the conduit 505 penetrates through the upper cover 501 and extends to the inner wall of the upper cover 501 where an electronically controlled pressurized spray head 506 is installed. Only by turning on the switch of the controller 503, the controller 503 controls the electronically controlled water pump 504 to operate, so that the electronically controlled water pump 504 pumps out the hot water in the water storage housing 502 to fill the conduit 505 with hot water. Subsequently, the controller 503 controls the electronically controlled pressurized spray head 506 to open, so that the hot water sprays out high-pressure hot water through the electronically controlled pressurized spray head 506 to wash the inner cavity of the separator housing 4. At the same time, the controller 503 controls the heating pipe 3 to heat, so that the heating pipe 3 heats the separator housing 4, causing the liquid in the inner cavity of the separator housing 4 to heat up, and the oil-absorbing substances to melt, facilitating the flushing by the electronically controlled pressurized spray head 506, making it easier to clean the separator housing 4. The sewage from the cleaning flows out through the sewage pipe 11. The device does not need to be manually flushed. By combining multiple structures, the cleaning efficiency is higher, which helps to solve the problem that after a period of operation, if not cleaned regularly, a large amount of grease and other residues will accumulate on the inner wall of the oil-water separator, which will not only affect the separation efficiency of the equipment but also reduce the overall service life of the oil-water separator equipment.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
