Description

Technical Field

[0001] The present application relates to the technical field of oil-water separation, and in particular, to a novel oil-water separator. Background Art

[0002] A large amount of wastewater is generated during industrial production processes. This wastewater contains waste oil, and since the density of the waste oil is smaller than that of water, the waste oil will float on the water surface. If the wastewater is directly discharged, it will cause environmental pollution. Therefore, oil removal devices are generally equipped in factories. The commonly used oil removal device in factories is an oil skimmer, which is also known as an oil skimmer, an oil-water separator, a floating oil removal machine, etc. The oil skimmer utilizes specific physical properties between oil and water and continuously works through an annular steel belt to adsorb and remove the floating oil on the surface of the wastewater. However, the amount of oil skimmed by the oil skimmer is relatively small.

[0003] In the prior art, there is an oil-water separation device that does not require power consumption. This oil-water separation device generally has a separation tank, a water outlet pipe, and an oil outlet. The oil outlet is located above the water outlet pipe. Since the oil floats on the water surface, the oil is discharged from the oil outlet, and the water is drained from the water outlet pipe.

[0004] However, during the continuous operation of the existing oil-water separation device, due to the continuous discharge of wastewater into the separation tank, waves are generated on the surface of the separation tank, which easily causes some water on the liquid surface to be discharged from the oil outlet together with the oil. As a result, the separated oil contains a certain amount of water, and the separated water contains a certain amount of oil, leading to poor oil-water separation effect. Summary of the Utility Model

[0005] The purpose of the present application is to provide a novel oil-water separator to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present application provides a novel oil-water separator adopting the following technical solution:

[0007] A novel oil-water separator includes a separation tank. A first partition and a second partition are arranged in the separation tank. The first partition and the second partition divide the separation tank into a liquid inlet chamber, a separation chamber, and a circulation chamber. A water inlet is arranged on the side of the liquid inlet chamber. The first partition is arranged on the side close to the water inlet. A flow stabilizing component, a baffle, a flow blocking plate, a high wall plate, and an oil receiver are arranged in the separation chamber. The flow stabilizing component is arranged on the side close to the first partition. The high wall plate is arranged beside the second partition, and there is a gap between the bottom end of the high wall plate and the bottom of the separation chamber. The height of the upper surface of the high wall plate is higher than the upper surfaces of the first partition and the second partition respectively. The baffle is arranged beside the flow stabilizing component and close to the high wall plate. There is also a gap between the bottom end of the baffle and the bottom of the separation chamber. The flow blocking plate is arranged between the baffle and the high wall plate. The bottom end of the flow blocking plate is hermetically fixed on the bottom wall of the separation chamber. The oil receiver is fixed on the side wall of the high wall plate;

[0008] A drain port is connected to the bottom of the liquid inlet chamber and the separation chamber, and a water return port is connected to the bottom of the circulation chamber.

[0009] Preferably, the flow stabilizing component includes two vertically symmetrically arranged struts, which are fixed on the side walls of the separation tank. A plurality of layers of V-shaped plates are uniformly fixed between the two struts on both sides, and the openings of the V-shaped plates face downward.

[0010] By adopting the above technical solution, during the process of water flowing to the right, through the blockage of the multi-layer V-shaped plates, the up-and-down surging of the water flow can be reduced, thereby stabilizing the fluctuation of the water surface, promoting the oil in the water to float upward, and accelerating the oil-water separation.

[0011] Preferably, in order to slow down the flow rate of water and leave more separation time, a plurality of baffles are provided.

[0012] Preferably, in order to prevent water from impacting the water surface and causing large waves, an inclined baffle is provided at the position of the liquid inlet chamber corresponding to the water inlet.

[0013] A drain pipe is connected to the bottom of the oil collector, and an oil outlet is connected to the bottom end of the separation chamber. The drain pipe is communicated with the oil outlet.

[0014] In summary, the present application includes at least one of the following beneficial technical effects: The new oil-water separator is provided with a flow stabilizing component and multiple baffles. By using the baffles to reduce the flow rate of water in the separation chamber and increase the residence time of water, the separation effect can be improved. And through the multi-layer V-shaped plates in the flow stabilizing component, the route of the up-and-down surging of the water flow is cut off, the fluctuation of the water surface can be stabilized, the oil in the water can be promoted to float upward, and the separation effect is better.

[0018] The following will further describe the present application in detail Figure 1-2 with reference to the accompanying drawings.

[0019] The embodiments of the present application disclose a novel oil-water separator. Refer to Figure 1-2 , which includes a separation tank 1. A first partition 11 and a second partition 12 are arranged in the separation tank 1. The first partition 11 and the second partition 12 divide the separation tank 1 into a liquid inlet chamber 13, a separation chamber 14 and a circulation chamber 15. A water inlet 16 is arranged on the side of the liquid inlet chamber 13. The first partition 11 is arranged on the side close to the water inlet 16. A flow stabilizing component 2, a baffle 3, a flow blocking plate 4, a high wall plate 5 and an oil collector 6 are arranged in the separation chamber 14. The flow stabilizing component 2 is arranged on the side close to the first partition 11. The high wall plate 5 is arranged beside the second partition 12, and there is a gap between the bottom end of the high wall plate 5 and the bottom of the separation chamber 14. The height of the upper surface of the high wall plate 5 is higher than the height of the upper surfaces of the first partition 11 and the second partition 12 respectively. The baffle 3 is arranged beside the flow stabilizing component 2 and close to the high wall plate 5. There is also a gap between the bottom end of the baffle 3 and the bottom of the separation chamber 14. Specifically, the number of the baffles 3 is set to be multiple. The arrangement of the multiple baffles 3 can slow down the flow rate of the water flow and increase the layering time. The flow blocking plate 4 is arranged between the baffle 3 and the high wall plate 5. The bottom end of the flow blocking plate 4 is hermetically fixed on the bottom wall of the separation chamber 14. The oil collector 6 is fixed on the side wall of the high wall plate 5. A drain pipe is connected to the bottom of the oil collector 6. An oil outlet 7 is connected to the bottom end of the separation chamber 14. The drain pipe is communicated with the oil outlet 7;

[0020] A drain port 8 is connected to the bottoms of the liquid inlet chamber 13 and the separation chamber 14. A water return port 9 is connected to the bottom of the circulation chamber 15.

[0021] Refer to Figure 1 and Figure 2 , the flow stabilizing component 2 includes two vertically symmetrically arranged struts 21. The struts 21 are fixed on the side walls of the separation tank 1. A plurality of layers of V-shaped plates 22 are evenly fixed between the two side struts 21. The openings of the V-shaped plates 22 face downward.

[0022] By arranging a plurality of layers of V-shaped plates 22, during the process of water flowing to the right, through the blocking of the plurality of layers of V-shaped plates 22, the up-and-down surging of the water flow can be reduced, so that the fluctuation of the water surface can be stabilized, promoting the oil in the water to float upward and accelerating the oil-water separation.

[0023] Refer to Figure 1 , in order to prevent the water from impacting the water surface and causing large waves, a slantingly arranged shielding plate 17 is arranged at the position of the liquid inlet chamber 13 corresponding to the water inlet 16.

[0024] The implementation principle of a novel oil-water separator in the embodiments of the present application is as follows:

[0025] The wastewater enters the liquid inlet chamber 13 from the water inlet 16. When the liquid inlet chamber 13 is filled with wastewater, it overflows the first partition 11 and enters the separation chamber 14, gradually filling the separation chamber 14. During this process, the water flow is blocked by multiple baffles 3, resulting in a slower flow rate. The lower layer of water flows through the gaps at the bottom of the baffles 3, while the oil layer floats on the upper layer, achieving a better layering effect. At the same time, with the installation of the flow stabilizing component 2, the water continuously rushing down from the first partition 11 will cause the water to surge up and down, generating a large number of waves on the water surface. The multiple V-shaped plates 22 in the flow stabilizing component 2 can effectively cut off the route of the water surging up and down, thus stabilizing the water surface fluctuations, promoting the oil in the water to float upward and the water to be below, achieving a better layering. The upper layer of oil will enter the oil collector 6 and be discharged, while the lower layer of water is discharged from the drain port 8.

[0026] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, any equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
