Description

Technical Field

[0001] This application relates to the technical field of equipment for treating oily liquids, and in particular to an oil-water separation device for oily mixed liquids. Background Technology

[0002] In some industrial cleaning processes, a certain amount of oily mixed liquid is generated. If this oily liquid is discharged directly, it will have an impact on the environment. Therefore, oil-water separation is required before discharge to facilitate subsequent purification treatment. Among the existing oil-water separation methods, static separation is the main method. However, static separation is slow, and it is still difficult to separate wastewater with low oil content after static separation. It is not suitable for separating some large-volume, flowing oily wastewater. Therefore, some automatic separation equipment is used to assist in oil-water separation. However, in some areas such as gas stations where it is not convenient to operate mechanical equipment, non-powered separation structures are still required. Therefore, it is necessary to improve the existing static separation tanks to solve these problems. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this application is to provide an oil-water separation device for oil-containing mixed liquids that does not require external power, has good separation effect, is easy to install, and has a wide range of applications.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] An oil-water separation device for an oil-containing liquid mixture includes: a support tank, a connecting frame, an annular distributor, an inlet channel, an outlet tank, a partition plate, a first distributor port, a second distributor port, a partition plate A, an outlet A, a drain port, and an outlet B. The support tank is rectangular in shape, with an open upper end. The connecting frame is symmetrically fixed to both sides of the middle position of the support tank. The annular distributor is fixedly connected to the inner side of the connecting frame. The annular distributor has a spiral flow channel inside, with the outer side of the bottom surface of the spiral flow channel lower than the inner side. The inlet channel is obliquely arranged, and its lower end is connected to the upper end of the annular distributor. The inlet channel enters along the tangent of the upper end of the annular distributor. One end of the outlet tank is connected to the lower end of the annular distributor, and the outlet tank is obliquely arranged. The liquid outlet trough is connected tangentially along the lower end of the spiral channel of the annular diverter. The partition plate is fixedly connected to the inner wall of the middle part of the support box. The liquid outlet trough passes through the upper end of the support box separated by the partition plate. The first diversion port is located on the lower surface of the outer side of the liquid outlet trough, and the second diversion port is located on the lower surface of the end of the liquid outlet trough. The first diversion port and the second diversion port are located at the upper ends of the partition plate. The partition plate A is fixedly connected to the inner wall of the partition plate near the upper position on one side of the liquid outlet trough. There is a gap between the bottom of the partition plate A and the support box. The liquid outlet A is located below the support box on the side of the partition plate away from the liquid outlet trough. The liquid drain is located on the support box on the side of the first diversion port. The liquid outlet B is vertically opened on the support box near the side of the second diversion port.

[0006] Optionally, the lowermost end of the liquid outlet B is higher than the uppermost end of the liquid outlet A, and the uppermost end of the gap between the partition A and the bottom of the support box is lower than the lowermost end of the liquid outlet A.

[0007] Optionally, a flow guide seat is also included, which is fixedly connected to the surface of the bearing box corresponding to the outside of the liquid outlet B.

[0008] Optionally, a sealing plate is also included, which is connected between the guide seat and the liquid outlet B.

[0009] Optionally, it also includes a bottom baffle and a baffle plate. The bottom baffle is fixedly connected to the bottom of the carrying box near the first diversion port. The baffle plate is fixedly connected to the inner wall of the carrying box on the side of the bottom baffle away from the first diversion port. The other side of the baffle plate is fixedly connected to a partition plate. A gap is provided between the bottom of the baffle plate and the bottom of the carrying box, and the gap is lower than the height of the bottom baffle.

[0010] Optionally, a sealing door panel is also included, which is fitted and connected to the outside of the drain port.

[0011] Optionally, it also includes support legs, which are fixedly connected to the lower surface of the support box in a rectangular array.

[0012] This oil-water separation device for oily mixed liquids accelerates the flow rate of the liquid through the inlet channel. As the oily liquid enters the annular distributor, it forms a thinner water flow. Under the action of neutralization, the water flows towards the edge, while the oil flows towards the center, thus achieving the separation of the two.

[0013] In this oil-water separation device for oily mixed liquids, the liquid flows downwards, and because the bottom surface of the annular channel is lower on the outside and higher on the inside, the flow velocity of the water is further increased, making the velocity difference between the two liquids greater and the separation effect more obvious.

[0014] This oil-water separation device for oily mixed liquids separates the water and the oil-enriched liquid into two spaces formed by a partition plate inside the support tank. Furthermore, the two spaces are equipped with partition plates A and other structures to achieve further separation or enrichment, greatly improving the rapid separation process of oily mixed liquids.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] To better understand the technical solutions presented in the embodiments of this application, the working principle of existing oil-water separation devices for oil-containing mixed liquids will first be introduced.

[0023] Existing oil-water separation structures use pool-like structures for storage, allowing the oil and water to separate after settling. The top oil-containing layer is then extracted and purified separately. However, existing structures suffer from low separation efficiency, require large containers for storage, are time-consuming, and have poor separation results. Therefore, it is necessary to improve existing oil-containing mixed liquid separation structures to solve these problems.

[0024] Please see Figures 1 to 5 This application discloses an oil-water separation device for an oil-containing liquid mixture, comprising: a support box 1, a connecting frame 2, an annular diverter 3, an inlet channel 4, an outlet tank 5, a partition plate 6, a first diverter port 7, a second diverter port 8, a partition plate A9, an outlet port A10, a drain port 11, and an outlet port B12. The support box 1 is rectangular in shape, with an open upper end. The connecting frame 2 is symmetrically fixed to both sides of the middle position of the support box 1. The annular diverter 3 is fixedly connected to the inner side of the connecting frame 2. The annular diverter 3 has a spiral flow channel inside, with the outer side of the bottom surface of the spiral flow channel lower than the inner side. The inlet channel 4 is obliquely arranged, with its lower end communicating with the upper end of the annular diverter 3. The inlet channel 4 enters along the tangent of the upper end of the annular diverter 3. One end of the outlet tank 5 is communicating with the lower end of the annular diverter 3, and the outlet... The trough 5 is inclined and the outlet trough 5 is connected through the tangent at the lower end of the spiral channel of the annular diverter 3. The partition plate 6 is fixedly connected to the inner wall of the middle part of the carrier box 1. The outlet trough 5 passes through the upper end of the carrier box 1 separated by the partition plate 6. The first diversion port 7 is set on the lower surface of the outer side of the outlet trough 5, and the second diversion port 8 is set on the lower surface of the end of the outlet trough 5. The first diversion port 7 and the second diversion port 8 are respectively located at the upper ends of the partition plate 6. The partition plate A9 is fixedly connected to the inner wall of the partition plate 6 on one side of the outlet trough 5 at the upper position. There is a gap between the bottom of the partition plate A9 and the carrier box 1. The outlet A10 is located at the lower position of the carrier box 1 on the side of the partition plate A9 away from the outlet trough 5. The drain port 11 is located on the carrier box 1 on the side of the first diversion port 7. The outlet B12 is vertically opened on the carrier box 1 on the side of the second diversion port 8.

[0025] Specifically, during use, oily liquid flows through a certain flow rate to the top of the inlet channel 4, where it accelerates downwards under gravity and enters the annular distributor 3 tangentially. The annular distributor 3 contains multiple layers of annular channels, causing the liquid to rotate. During this process, the water experiences greater centrifugal force and travels along the edge of the annular channels. Furthermore, the channels are designed with the outer side lower than the inner side, further causing water to flow outwards while oil converges towards the inner side of the annular structure, achieving oil collection. Upon reaching the bottom of the annular distributor 3, the outlet channel 5 is also tangential, with a first diversion port 7 on its outer side to allow water to drain, while oil or liquids with a high oil content flow inwards. The liquid flows forward from the side of the outlet tank 5 and then enters the second diversion port 8 to achieve the separation process. The partition plate 6 can divide the space inside the carrying tank 1 into two spaces for holding the two liquids respectively. The partition plate A9 can further isolate the water contained in the separated oil, so that the water is discharged from the lower end of the partition plate A9 through the outlet port A10, while the oil is collected on the other side. The drain port 11 is used to discharge the water, and the drain port 11 has a large diameter, which facilitates subsequent maintenance and repair. Compared with the existing oil-water separation structure, this structure improves the separation efficiency and the processing speed. It can accelerate the oil-water separation process without the participation of external power, improve the wastewater purification speed, and has good practicality, making it suitable for use in special places such as oil depots and factories.

[0026] Please see Figure 1 As another specific embodiment provided in the application, the lowest point of the liquid outlet B12 is higher than the upper point of the liquid outlet A10, and the uppermost point of the gap between the partition A9 and the bottom of the bearing box 1 is lower than the lowest point of the liquid outlet A10.

[0027] Specifically, the setting of outlet B12 being higher than outlet A10 allows for more thorough water discharge.

[0028] Please see Figure 2 As another specific embodiment provided in the application, it also includes a flow guide seat 13, which is fixedly connected to the surface of the bearing box 1 corresponding to the outside of the liquid outlet B12.

[0029] Specifically, the guide seat 13 can guide the oil discharged from the outlet B12, making it easier for subsequent processing equipment to collect it. Alternatively, other collection structures can be used to replace it to meet the oil processing requirements.

[0030] Please see Figure 2 As another specific embodiment provided in the application, it also includes a sealing plate 14, which is connected between the flow guide seat 13 and the liquid outlet B12.

[0031] Specifically, the sealing plate 14 can seal the elongated liquid outlet B12, and during the sealing process, it moves downward to adjust the overflow position at the upper end of the liquid outlet B12, which is convenient for continuous processing.

[0032] Please see Figure 3 As another specific embodiment provided in the application, it also includes a bottom baffle 15 and a baffle plate 16. The bottom baffle 15 is fixedly connected to the bottom of the carrier box 1 on the side close to the first diversion port 7. The baffle plate 16 is fixedly connected to the inner wall of the carrier box 1 on the side of the bottom baffle 15 away from the first diversion port 7. The other side of the baffle plate 16 is fixedly connected to the partition plate 6. A gap is provided between the bottom of the baffle plate 16 and the bottom of the carrier box 1, and the gap is lower than the height of the bottom baffle 15.

[0033] Specifically, the bottom baffle 15 creates resistance to the flow of liquid, allowing the oil remaining in the water to be separated. When the flow rate is constant, the remaining oil will collect at the top in the space of the bottom baffle 15 on the side of the first diversion port 7, while the water will pass through the holes at the lower end of the baffle plate 16 and be discharged, thus achieving the re-collection of the remaining oil. When a certain amount is reached, it can be extracted from the carrier box 1 by means of extraction or other methods. Compared with the existing separation structure, the separation of this structure is more thorough.

[0034] Please see Figure 1 As another specific embodiment provided in the application, it also includes a sealing door plate 17, which is connected to the outside of the drain port 11.

[0035] Specifically, the sealing door 17 can seal the drain port 11 or adjust its discharge speed.

[0036] Please see Figure 1 As another specific embodiment provided in the application, it also includes support legs 18, which are fixedly connected to the lower surface of the bearing box 1 in a rectangular array.

[0037] Specifically, the support legs 18 can stably support the load-bearing box 1 to a certain height, which facilitates actual installation and use.

[0038] The embodiments described in this specific implementation are 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.
