Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology for oily wastewater, and in particular to an oil-water separation tank with an adjustable weir plate for oily wastewater. Background Technology

[0002] An oil-water separator is a device used to treat industrial or domestic wastewater containing oil. Its main function is to separate oil and water in wastewater through physical methods in order to purify water, recover oil, or meet emission standards.

[0003] Currently, commonly used oil-water separation equipment mainly includes gravity oil separators, inclined plate oil separators, air flotation devices, and membrane separation equipment. Among them, gravity separation is widely used in the primary treatment stage of oily wastewater due to its simple structure, low operating cost, and convenient maintenance. A typical gravity oil-water separator utilizes the density difference between oil and water to achieve a natural separation process where oil floats and water sinks under static or slow-flow conditions. However, traditional oil-water separators have technical defects: because the outlet position is fixed, it is impossible to dynamically adjust the outlet water level according to the actual influent water quality, water volume fluctuations, or oil layer thickness. This easily leads to the floating oil in the upper part of the separation zone overflowing from the outlet with the water flow, resulting in excessive oil content in the effluent.

[0004] Therefore, an oil-water separator with an adjustable weir plate is needed for oily wastewater. Utility Model Content

[0005] To overcome the shortcomings of traditional oil-water separators, which have fixed outlet positions and cannot dynamically adjust the outlet water level according to the actual water quality, water volume fluctuations, or oil layer thickness, which easily leads to the floating oil in the upper part of the separation zone overflowing from the outlet with the water flow and causing the oil content of the effluent to exceed the standard, this utility model provides an oil-water separator for oily wastewater with adjustable weir plates.

[0006] The technical solution of this utility model is: an oil-water separator for oily wastewater with an adjustable weir plate, comprising a support frame, a separator tank, a water outlet pipe, an interceptor plate, an oil outlet pipe, and a valve. The separator tank is fixedly connected to the top of the support frame. The water outlet pipe is connected and communicated to the lower right side of the separator tank. The water outlet pipe is inclined. An interceptor plate is installed inside the separator tank. The interceptor plate is inclined from left to right. An oil outlet pipe is connected and communicated to the right side of the interceptor plate. The oil outlet pipe passes through the separator tank. A valve is installed on the oil outlet pipe. The separator tank also includes a connecting rod, a weir plate, a damping ring, and a handle. Connecting rods are rotatably installed on both the front and rear sides of the separator tank. The two connecting rods are fixedly connected to the weir plate, which is in contact with the water outlet pipe. Damping rings are installed on both the front and rear sides of the separator tank. The damping rings are in close contact with the connecting rods. A handle is fixedly connected to the connecting rod.

[0007] Furthermore, it also includes a clamping plate, a filter plate, and a pull rod. The clamping plates are slidably installed on both the left and right sides of the separation tank. The two clamping plates are of different lengths. The filter plate is fixedly connected to the clamping plate. The filter plate is located in the upper part of the separation tank. The pull rod is fixedly connected to the top of the clamping plate.

[0008] Furthermore, it also includes a fixing plate, an angle ruler, and a pointer plate. The front and rear sides of the lower part of the separation tank are fixedly connected to the fixing plate, the angle ruler is installed on the fixing plate, and the pointer plate is fixedly connected to the connecting rod.

[0009] Furthermore, it also includes a connector, with a connector installed at the right end of the oil outlet pipe.

[0010] Furthermore, it also includes an anti-slip sleeve, which is fitted onto the handle.

[0011] Furthermore, it also includes rubber rings. Rubber rings are provided on both the left and right sides of the upper part of the separation tank, and the rubber rings are inserted into the limiting grooves of the card plate.

[0012] Compared with the prior art, this utility model provides an oil-water separator for oily wastewater with an adjustable weir plate, which has the following beneficial effects: 1. By turning the handle, the connecting rod can be rotated, thereby synchronously adjusting the angle of the weir plate fixed on the connecting rod, controlling the discharge level of the water phase in the tank, ensuring that the oil layer has sufficient thickness and stable space to accumulate, and at the same time, allowing the separated clear water to overflow smoothly when it reaches the predetermined level, thereby achieving efficient oil-water separation and preventing the oil phase from being carried out by the water phase.

[0013] 2. When oily wastewater enters from the top of the tank, it will first pass through this filter plate, thereby removing solid impurities from the wastewater and improving the subsequent oil-water separation effect.

[0014] 3. The real-time tilt angle of the weir plate can be read visually from the outside using the pointer plate and the angle gauge on the outside of the separation tank, thereby achieving precise control of the rotation angle of the weir plate and improving the convenience of operation.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: An oil-water separator for oily wastewater with an adjustable weir plate. Please refer to [link / reference]. Figures 1-5 The system includes a support frame 1, a separation tank 2, a water outlet pipe 3, a baffle plate 4, an oil outlet pipe 5, and a valve 6. The separation tank 2 is fixedly connected to the top of the support frame 1. The water outlet pipe 3 is connected and connected to the lower right side of the separation tank 2. The water outlet pipe 3 is inclined. The baffle plate 4 is installed inside the separation tank 2. The baffle plate 4 is inclined from left to right. The oil outlet pipe 5 is connected and connected to the right side of the baffle plate 4. The oil outlet pipe 5 passes through the separation tank 2. The valve 6 is installed on the oil outlet pipe 5. The system also includes a connecting rod 8, a weir plate 9, a damping ring 10, and a handle 11. The connecting rod 8 is rotatably installed on both the front and rear sides of the separation tank 2. The two connecting rods 8 are fixedly connected together. There is a weir plate 9, which contacts the water outlet pipe 3. Damping rings 10 are provided on both the front and rear sides of the separation tank 2. The damping rings 10 are in close contact with the connecting rod 8. A handle 11 is fixedly connected to the connecting rod 8. The damping rings 10 on both the front and rear sides of the separation tank 2 are in close contact with the connecting rod 8, providing sufficient frictional damping to ensure that the weir plate 9 can be stably maintained after being adjusted to the required angle, and will not easily move due to external forces such as water flow impact. A connector 7 is provided at the right end of the oil outlet pipe 5 to facilitate the connection of the oil outlet pipe 5 to external conveying equipment. An anti-slip sleeve 12 is fitted on the handle 11 to increase the friction between the hand and the handle 11 and prevent slippage.

[0023] When using an oil-water separator for oily wastewater, the oily wastewater first enters the tank from the top of the separator 2 through the inlet pipe. Under gravity, it undergoes natural sedimentation and oil-water separation. Since the density of oil is less than that of water, oil droplets float to the surface to form an oil layer, while the heavier water phase sinks to the lower layer, achieving initial separation. During this process, the inclined interceptor plate 4 effectively blocks and guides the upper oil layer to gather on the right and discharge it through the connected oil outlet pipe 5. The valve 6 on the oil outlet pipe 5 is used to control the opening and closing of the oil discharge process, facilitating intermittent or on-demand discharge. While discharging floating oil, the connecting rod 8 can be rotated by turning the handle 11, thereby synchronously adjusting the angle of the weir plate 9 fixed on the connecting rod 8. Since the lower edge of the weir plate 9 and the inlet of the water outlet pipe 3 together form a variable water outlet weir, adjusting the angle of the weir plate 9 essentially changes the effective height of the water outlet weir, thereby controlling the discharge level of the water phase in the tank, ensuring that the oil layer has sufficient thickness and stable space to accumulate, and at the same time, allowing the separated clear water to overflow smoothly when it reaches the predetermined level, thereby achieving efficient oil-water separation and preventing the oil phase from being carried out by the water phase.

[0024] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 4 It also includes a clamping plate 13, a filter plate 14, and a pull rod 15. The clamping plates 13 are slidably installed on both the left and right sides of the separation tank 2. The two clamping plates 13 have different lengths. The filter plate 14 is fixedly connected to the clamping plate 13. The filter plate 14 is located in the upper part of the separation tank 2. The pull rod 15 is fixedly connected to the top of the clamping plate 13. Rubber rings 16 are provided on both the left and right sides of the upper part of the separation tank 2. The rubber rings 16 are inserted into the limiting groove of the clamping plate 13 to enhance the stability of the clamping plate 13 installation and prevent the clamping plate 13 from loosening.

[0025] Before using the oil-water separator for oily wastewater, two clamping plates 13 of different lengths can be slidably installed at the two openings on the top of the separator 2. A filter plate 14 is connected to the inside of the clamping plates 13. When the clamping plates 13 are installed in place, the filter plate 14 extends into the upper space of the separator 2. When the oily wastewater enters from the top of the tank, it will first pass through this filter plate 14, thereby filtering out solid impurities in the wastewater and improving the subsequent oil-water separation effect.

[0026] Please see Figure 1 and Figure 5 It also includes a fixing plate 17, an angle ruler 18 and a pointer plate 19. The fixing plate 17 is fixedly connected to both the front and rear sides of the lower part of the separation tank 2. An angle ruler 18 is provided on the fixing plate 17, and the pointer plate 19 is fixedly connected to the connecting rod 8.

[0027] When adjusting the weir plate 9, the real-time tilt angle of the weir plate 9 can be read visually from the outside through the pointer plate 19 and the angle ruler 18 on the outside of the separation tank 2, thereby achieving precise control of the rotation angle of the weir plate 9 and improving the convenience of operation.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
