Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, in particular to an oil-water separator which is easy to clean. Background Art

[0002] Wastewater is often produced in the chemical industry production process, and the wastewater contains oil. If the oil in the chemical wastewater is not separated and discharged, it will cause great damage to the environment. Therefore, an oil-water separator is needed. The oil-water separator is an instrument that separates oil and water.

[0003] Publication No. CN219314646U discloses an oil-water filter separator, and in particular, relates to an oil-water filter separator, wherein a honeycomb metal grid is provided inside the oil-water separation tank, a cooling coil is provided inside the honeycomb metal grid, a transmission shaft is inserted in the reserved groove in the middle of the honeycomb metal grid, and a stirring short paddle is connected in the middle of the transmission shaft, and a stirring long paddle is connected at the bottom of the transmission shaft; the upper end of the transmission shaft is connected to the driving motor at the top of the oil-water separation tank, and drives the stirring short paddle and the stirring long paddle to rotate; the bottom of the oil-water separation tank is provided with several aeration nozzles, and the aeration nozzles are connected to an external pressurized air pump. It uses a honeycomb grid with a low-temperature coil to cool the oil-water mixture, so that the oil condenses on the honeycomb grid to achieve oil-water separation; at the same time, the aeration equipment can drive the oil to float to avoid mixing residual oil in the drainage during the stirring process. However, the separator cannot concentrate the oil in the wastewater when in use, which is inconvenient for the staff to clean up, reducing the use effect of the separator. The separator still has shortcomings and needs to be improved. Utility Model Content

By setting up structures such as a fixed plate 9, a motor 10, a threaded rod 11, a connecting plate 12 and a scraper 13, the motor 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the connecting plate 12 and the scraper 13 to slide inside the oil-water separation tank 1 during the rotation process. The scraper 13 pushes the oil floating on the surface of the wastewater to the location of the step 20 during the sliding process. Then the staff can climb the step 20 to clean up the gathered oil. This structure can quickly concentrate the oil in the wastewater, thereby making it convenient for the staff to clean up and improving the use effect of the separator.

[0025] See also Figure 1-2 and Figure 4 The air pipe 7 is fixedly connected to the oil-water separation tank 1, and the scraper 13 is slidably connected to the oil-water separation tank 1. The sliding connection improves the limiting effect of the connecting plate 12. A protective cover 14 is fixedly installed on the side of the fixed plate 9 close to the motor 10. The protective cover 14 improves the protection effect of the motor 10. The oil-water separation tank 1 is interconnected with the water inlet pipe 2 and the drain pipe 3.

The ladder 20 facilitates the staff to climb up to handle the oil in the oil-water separation tank 1.

[0026] Embodiment 2

[0027] See also Figure 2-3, slots 15 are symmetrically provided on both sides of the bottom plate 5, and a plug strip 16 is slidably connected inside the slot 15. The plug strip 16 drives the protective shell 17 to slide inside the slot 15, thereby improving the removal efficiency of the protective shell 17. The outer side of the plug strip 16 is fixedly installed with a protective shell 17, and the protective shell 17 improves the protection effect of the air pump 6. The outer surface of the protective shell 17 is fixedly installed with a handle 18. The two sides of the protective shell 17 are symmetrically provided with heat dissipation grooves 19, and the heat dissipation effect of the air pump 6 is improved by the heat dissipation grooves 19. By setting the slot 15, the plug strip 16, the protective shell 17 and the handle 18 and other structures, the protective shell 17 improves the protection effect of the air pump 6. When the air pump 6 is damaged, the handle 18 can be pulled, and the protective shell 17 and the plug strip 16 can be driven to slide inside the slot 15 by the handle 18. After sliding a certain distance, the protective shell 17 can be removed. This structure improves the protection effect of the air pump 6 through the protective shell 17. At the same time, when the air pump 6 is damaged, the protective shell 17 can also be quickly disassembled, thereby making it convenient for the staff to repair the air pump 6.

[0028] Working principle: when in use, first transport the wastewater from the water inlet pipe 2 to the inside of the oil-water separation tank 1, and start the air pump 6 after transporting a certain amount. The air pump 6 will transport gas into the air pipe 7 when working. After transporting a certain amount, the gas in the air pipe 7 will be sprayed out from the nozzle 8. After the gas is sprayed out, bubbles will be generated in the wastewater in the oil-water separation tank 1. After the bubbles are generated, the oil in the wastewater will float up. When there is too much floating oil, the motor 10 can be started, and the threaded rod 11 can be driven to rotate by the motor 10. During the rotation, the threaded rod 11 will drive the connecting plate 12 and the scraper 13 to slide inside the oil-water separation tank 1. During the sliding process, the scraper 13 will push the oil floating on the surface of the wastewater to the location of the step 20, and then the staff can climb the step 20 to clean the gathered oil. After the cleaning is completed, the valve 4 can be opened, and the wastewater will be discharged from the drain pipe 3 after opening. When the air pump 6 is in use, the protective shell 17 can be used to improve the protection effect of the air pump 6. When the air pump 6 is damaged, the handle 18 can be pulled to drive the protective shell 17 and the insert 16 to slide inside the slot 15. After sliding a certain distance, the protective shell 17 can be removed, and then the damaged air pump 6 can be repaired.
