Description

Technical Field

[0001] This application relates to the technical field of oil-water separation equipment, and in particular to a separation component of an oil-water separator. Background Technology

[0002] Oil-water separators are widely used in industrial production and daily life to treat oily wastewater, and the performance of the separation components directly affects the efficiency and effectiveness of oil-water separation. In existing oil-water separators, the cylindrical filter screen used to filter impurities accumulates a large amount of oil and solid impurities on its surface over long-term use, causing it to gradually become clogged. If not cleaned in time, this significantly reduces the filtration efficiency. However, traditional cleaning methods require removing the filter screen from the storage cylinder for cleaning, which is cumbersome and interrupts the oil-water separation process, affecting the overall work progress.

[0003] A search revealed that Chinese Patent Publication No. CN222631141U discloses a high-efficiency oil-water separation and filtration device, including a tank. The tank contains a coalescing filter element and a separating filter element, which are arranged symmetrically on the left and right sides. The bottom of the coalescing filter element is fixed with a coalescing filter seat that is fixedly connected to the inner wall of the tank. The bottom of the separating filter element is fixed with a separating filter seat that is fixedly connected to the inner wall of the tank. The bottom of the separating filter seat is fixed with an outlet pipe that penetrates the bottom of the tank. The bottom of the coalescing filter seat is fixed with an inlet pipe that penetrates the bottom of the tank. The bottom of the tank is fixed with a drain pipe that communicates with the interior of the tank.

[0004] Regarding the aforementioned related technologies, the inventors discovered the following drawbacks: Existing technologies require the filter screen to be removed from the placement cylinder for cleaning, leading to interruptions in the oil-water separation operation. This application addresses the technical problem in existing oil-water separators where oil and solid impurities adhere to the surface of the filter cartridge, causing blockages and necessitating disassembly and cleaning, thus interrupting operations. By installing two filter components in the settling tank with identical inlet pipes, T-junctions, and connecting structures, each equipped with a filter cartridge and scraper, and utilizing impeller and bevel gear transmission to rotate the filter cartridge, coupled with a detachable lower end cover, the invention achieves uninterrupted operation through filter channel switching, automatic impurity removal via filter cartridge rotation and scraper, convenient impurity cleaning, and efficient oil diversion and collection. Utility Model Content

[0005] To improve the continuity of oil-water separation operations, this application provides a separation component for an oil-water separator.

[0006] This application provides a separation component for an oil-water separator, employing the following technical solution: It includes a settling tank with an inlet pipe; a three-way pipe connects to the bottom of the settling tank; one end of the three-way pipe is connected to a first filter component via a first valve, and the other end of the three-way pipe is connected to a second filter component with the same structure as the first filter component via a second valve; the first filter component includes a storage cylinder connected to the three-way pipe, within which a rotatable filter cylinder is coaxially arranged, and the filter cylinder has multiple filter holes on its peripheral wall; a scraper is installed inside the storage cylinder; a drain pipe is installed inside the storage cylinder and communicates with the inner cavity of the filter cylinder, with the other end of the drain pipe connected to a suction pump.

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] This application discloses a separation component for an oil-water separator. For example... Figure 1 As shown, it includes a settling tank 1, an inlet pipe 2, a three-way pipe 3, a first filter assembly, and a second filter assembly. The settling tank 1 is cylindrical, and an inlet pipe 2 is provided on the upper part of its side wall for introducing oily wastewater. The bottom center of the settling tank 1 is connected to the three-way pipe 3, and the two ends of the three-way pipe 3 are connected to the first filter assembly and the second filter assembly through the first valve 4 and the second valve 5, respectively, to realize the switching of the two filter channels.

[0025] Please see Figure 1 and Figure 2A first funnel 6 is fixedly installed on the lower inner wall of the settling tank 1. Its funnel opening faces downward and is connected to the inlet end of the three-way pipe 3. It is used to guide the settled liquid to flow into the three-way pipe 3 in a concentrated manner, thereby improving the flow efficiency. An inverted second funnel 7 is fixedly installed on the upper inner wall of the settling tank 1. Its funnel opening faces upward and is connected to the oil pump through a pipe. It is used to collect the floating grease and discharge it from the separation component through the oil pump. Several table legs 8 are fixedly connected to the bottom of the outer wall of the settling tank 1. Anti-slip pads are provided at the lower end of the table legs 8 to stably support the entire separation component.

[0026] Please see Figures 2-5 The first filtration assembly includes a liquid storage cylinder 9, which is connected to one end of a three-way pipe 3 via a pipe. A filter cylinder 10 is coaxially arranged inside the liquid storage cylinder 9. Multiple filter holes 11 are evenly opened on the peripheral wall of the filter cylinder 10 to intercept solid impurities in the liquid. A scraper 12 is fixedly installed on the inner wall of the liquid storage cylinder 9. The edge of the scraper 12 is in close contact with the outer wall of the filter cylinder 10 to scrape off impurities attached to the surface of the filter cylinder 10. The lower end face of the liquid storage cylinder 9 is open, and a detachable lower end cap 13 is threadedly connected to its lower part to facilitate the cleaning of deposited impurities. A drain pipe 14 is provided at the top of the liquid storage cylinder 9. One end of the drain pipe 14 extends into the inner cavity of the filter cylinder 10, and the other end is connected to a suction pump. When the suction pump is working, it can extract the filtered liquid.

[0027] Please see Figure 3 and Figure 4 An impeller 15 is installed inside one end of the three-way pipe 3 corresponding to the first filter assembly. The rotating shaft of the impeller 15 is coaxially fixed with the first bevel gear 16. A second bevel gear ring 17 is coaxially fixed to the outer side of the peripheral wall of the filter cylinder 10. The first bevel gear 16 meshes with the second bevel gear ring 17. When oily wastewater flows through the three-way pipe 3, the water flow drives the impeller 15 to rotate, which drives the filter cylinder 10 to rotate inside the liquid storage cylinder 9 through the bevel gear transmission.

[0028] Please see Figure 1 The first and second filter components have the same structure, and the liquid flow direction is controlled by the valves at both ends of the three-way pipe 3. When the filter cylinder 10 of one of the filter components is blocked by impurities, the corresponding valve is closed and the other filter component is turned on to achieve uninterrupted separation operation. At the same time, the blocked filter components can be cleaned.

[0029] The implementation principle of the separation component of the oil-water separator in this application embodiment is as follows: oily wastewater enters the settling tank 1 from the inlet pipe 2 and is initially settled in the settling tank 1. The denser solid particles sink to the first funnel 6, and the grease floats to the second funnel 7. The liquid flows into the three-way pipe 3 through the first funnel 6, the first valve 4 is opened (the second valve 5 is closed), and the liquid enters the storage cylinder 9 of the first filter component.

[0030] When the corresponding suction pump is started, the filter cylinder 10 rotates under the drive of the impeller 15. The liquid enters the inner cavity of the filter cylinder 10 through the filter hole 11 and is discharged through the drain pipe 14. Solid impurities are intercepted by the filter hole 11 and adhere to the outer wall of the filter cylinder 10. They are scraped off by the scraper 12 as the filter cylinder 10 rotates and are deposited at the bottom of the liquid storage cylinder 9. The grease is collected through the second funnel 7 and discharged by the oil pump, thus achieving oil-water separation.

[0031] The rotation of the filter cartridge 10, in conjunction with the scraper 12, can automatically remove impurities from the surface of the filter holes 11, preventing clogging. When a large amount of impurities accumulate at the bottom of the liquid storage cylinder 9, the lower end cap 13 can be removed for cleaning without disassembling the filter cartridge 10, making the operation convenient.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
