Description

An oil spill treatment device Technical Field

[0001] This invention relates to the field of liquid separation device technology, and more specifically, to an oil spill treatment device. Background Technology

[0002] During the cold rolling process of steel coils and steel products, emulsion is sprayed onto the rolling mill rolls. However, during rolling, leaks of hydraulic oil and lubricating oil, as well as deterioration of the emulsion itself due to temperature changes, can all cause floating oil to form on the surface of the emulsion, affecting its usability. Therefore, it is necessary to separate the emulsion and the floating oil. Since the emulsion is stored in the main oil tank, the floating oil produced after the emulsion deteriorates will float on its surface. To separate the emulsion and floating oil, an oil pump is typically used to transfer the mixture to a separation tank. After the emulsion and floating oil have settled, they automatically separate into two layers due to their different densities, thus separating the floating oil from the emulsion.

[0003] However, when transferring the mixture of emulsion and floating oil into the separation tank, the mixture may contain more emulsion and less floating oil. The amount of floating oil separated in the separation tank is also less, resulting in a smaller amount of floating oil being separated at one time. This requires transferring the mixture of emulsion and floating oil in the main tank multiple times, which takes a lot of time and is not conducive to the rapid separation of emulsion and floating oil.

[0004] Meanwhile, the transfer and separation processes of emulsions and floating oil often require manual adjustment, which cannot meet the needs of automated production. Summary of the Invention

[0005] The problem addressed by this invention is how to improve the separation efficiency of emulsions and floating oil.

[0006] To solve the above problems, the present invention provides an oil spill treatment device, including a main oil tank, a separation tank, an oil spill adsorption mechanism, a first driving mechanism, a second driving mechanism, a first pipeline, and a second pipeline. The main oil tank is used to hold an emulsion, and the surface layer of the emulsion is oil. The oil spill adsorption mechanism floats on the surface of the emulsion and is used to absorb the emulsion and the oil.

[0007] One end of the first pipeline near the main oil tank is connected to the upper end of the floating oil adsorption mechanism, and the other end of the first pipeline is connected to the separation tank; the first drive mechanism is disposed on the first pipeline and is used to drive the floating oil and the emulsion through the first pipeline into the separation tank;

[0008] The lower end of the second pipeline is connected to the lower end of the floating oil adsorption mechanism, and the upper end of the second pipeline is connected to the upper end of the main oil tank; the second drive mechanism is disposed on the second pipeline and is used to drive the emulsion and the floating oil in the main oil tank to circulate.

[0009] The technical effects of this invention are as follows: The first driving mechanism acts on the upper end of the oil adsorption mechanism, causing the upper layer of liquid in the main oil tank to move upward. Since the upper layer of liquid in the main oil tank mainly contains a large amount of oil and a small amount of emulsion, the first driving mechanism can guide a large amount of oil through the first pipeline into the separation tank. After the oil and emulsion settle in the separation tank, they can quickly separate into layers. Since the amount of oil is large and the amount of emulsion is small, the amount of oil separated in the separation tank at one time is large, thereby accelerating the efficiency of oil and emulsion separation.

[0010] The second driving mechanism acts on the lower end of the oil adsorption mechanism, causing the lower layer of liquid in the main oil tank to move downwards. Since the lower layer of liquid in the main oil tank mainly contains a large amount of emulsion and a small amount of floating oil, the second driving mechanism can guide more emulsion through the second pipeline from the lower layer of the main oil tank to the upper layer of the main oil tank. On the one hand, this provides power to the liquid in the main oil tank, making it easier for the liquid in the upper layer of the main oil tank to enter the oil adsorption mechanism. On the other hand, it can transfer the floating oil in the lower layer of the main oil tank to the upper layer of the main oil tank, making it easier for the oil adsorption mechanism to absorb more floating oil. As a result, the amount of floating oil separated in the separation tank at one time is larger, which can further accelerate the efficiency of oil and emulsion separation.

[0011] Meanwhile, the negative pressure generated by the driving action of the first driving mechanism and / or the second driving mechanism enables the floating oil adsorption mechanism to continuously absorb the emulsion and floating oil in the main oil tank, which can realize continuous and automated liquid separation and help to achieve automated production.

[0012] Optionally, the oil adsorption mechanism includes a funnel, an adsorption structure, and a flow-generating pipe. The funnel floats on the surface of the emulsion. A first notch is provided on the funnel to connect the funnel and the main oil tank. The funnel has openings at both the top and bottom. One end of the adsorption structure is connected to the first pipeline, and the other end is connected to the upper opening of the funnel. One end of the flow-generating pipe is connected to the second pipeline, and the other end is connected to the lower opening of the funnel.

[0013] Optionally, the oil adsorption mechanism further includes a guide ring. Both the funnel and the guide ring are cylindrical structures. The guide ring has a second notch. The guide ring is located outside the funnel and is used to fit into the funnel. The second notch is used to connect with the first notch.

[0014] Optionally, multiple first notches are provided, and the multiple first notches are evenly distributed around the funnel. Multiple second notches are provided, and the multiple second notches are evenly distributed around the guide ring. The multiple first notches and the multiple second notches correspond one-to-one.

[0015] Optionally, both the first notch and the second notch are configured as V-shaped.

[0016] Optionally, the openings of both the first notch and the second notch face upwards.

[0017] Optionally, the oil adsorption mechanism further includes a filler, and a cavity is provided below the funnel. The filler is used to be placed in the cavity and to adjust the draft of the funnel.

[0018] Optionally, the oil adsorption mechanism further includes a guide sleeve and a guide tube. The guide sleeve is vertically arranged and fixedly connected to the funnel. The guide tube is vertically arranged and fixedly connected to the main oil tank. The guide sleeve is slidably connected to the guide tube in the vertical direction.

[0019] Optionally, the adsorption structure includes an adsorption tube, a guide rail, and a slider. The guide rail is vertically arranged and detachably connected to the flow guide ring. The slider is slidably connected to the guide rail in a vertical direction. The adsorption tube is detachably connected to the slider. One end of the adsorption tube is connected to the first pipeline, and the other end is inserted into the liquid surface from the upper opening of the funnel.

[0020] Optionally, the oil spill treatment device further includes a first liquid component detection instrument and a second liquid component detection instrument, which are located on the upper and lower sides of the separation tank, respectively, and are both used to detect the conductivity of the liquid in the separation tank.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] In this embodiment, an X-axis coordinate system is established, with the positive X-axis pointing upwards and the negative X-axis pointing downwards.

[0035] To solve the above problems, as shown in Figure 1, an oil spill treatment device according to an embodiment of the present invention includes a main oil tank 1, a separation tank 2, an oil spill adsorption mechanism 3, a first driving mechanism 41, a second driving mechanism 42, a first pipeline 51, and a second pipeline 52. The main oil tank 1 is used to hold emulsion, and the upper layer of the emulsion is oil. The oil spill adsorption mechanism 3 floats on the surface of the emulsion and is used to absorb the emulsion and the oil.

[0036] The first pipeline 51 is connected to the upper end of the main oil tank 1 at one end, and the other end of the first pipeline 51 is connected to the separation tank 2. The first drive mechanism 41 is installed on the first pipeline 51 and is used to drive the floating oil and emulsion through the first pipeline 51 into the separation tank 2.

[0037] The lower end of the second pipeline 52 is connected to the lower end of the floating oil adsorption mechanism 3, and the upper end of the second pipeline 52 is connected to the upper end of the main oil tank 1; the second drive mechanism 42 is installed on the second pipeline 52 and is used to drive the emulsion and floating oil in the main oil tank 1 to circulate.

[0038] Specifically, the first drive mechanism 41 can be configured as a pneumatic diaphragm pump, pressure pump, or other structures, and the second drive mechanism 42 can be configured as a flow pump, pressure pump, or other structures. The first pipeline 51 and the second pipeline 52 can be configured as flexible or rigid pipes as needed.

[0039] In this embodiment, the emulsion and floating oil enter the floating oil adsorption mechanism 3. Since the density of the floating oil is less than that of the emulsion, the floating oil and emulsion will form layers within the floating oil adsorption mechanism 3, with the floating oil on the upper layer and the emulsion on the lower layer. When separating the emulsion and floating oil, the first driving mechanism 41 is driven to act on the liquid at the upper end of the floating oil adsorption mechanism 3. Based on the characteristic that the floating oil is on the upper layer and the emulsion is on the lower layer, most of the floating oil and a small portion of the emulsion can be guided through the first pipeline 51 from the main oil tank 1 into the separation tank 2. The second driving mechanism 42 is driven to act on the liquid at the lower end of the floating oil adsorption mechanism 3. Based on the specific characteristic that the floating oil is on the upper layer and the emulsion is on the lower layer, most of the emulsion and a small portion of the floating oil can be guided through the second pipeline 52 from the lower layer of the liquid surface in the main oil tank 1 to the upper layer of the liquid surface in the main oil tank 1. Furthermore, the negative pressure generated by the driving action of the first driving mechanism 41 and / or the second driving mechanism 42 can also enable the floating oil adsorption mechanism 3 to continuously absorb the emulsion and floating oil in the main oil tank 1.

[0040] In summary, the first driving mechanism 41 acts on the upper end of the oil adsorption mechanism 3, causing the upper liquid in the oil adsorption mechanism 3 to move upward. Since the upper liquid in the oil adsorption mechanism 3 mainly consists of a large amount of oil and a small amount of emulsion, the first driving mechanism 41 can guide a large amount of oil through the first pipeline 51 into the separation tank 2. After the oil and emulsion settle in the separation tank 2, they can quickly separate into layers. Since the amount of oil is large and the amount of emulsion is small, the amount of oil separated in the separation tank 2 at one time is large, which can accelerate the efficiency of oil and emulsion separation.

[0041] The second driving mechanism 42 acts on the lower end of the oil adsorption mechanism 3, causing the lower layer of liquid in the oil adsorption mechanism 3 to move downwards. Since the lower layer of liquid in the oil adsorption mechanism 3 mainly contains a large amount of emulsion and a small amount of floating oil, the second driving mechanism 42 can guide a large amount of emulsion through the second pipeline 52 from the lower layer of the main oil tank 1 to the upper layer of the main oil tank 1. On the one hand, it can provide power to the liquid in the main oil tank 1, making it easier for the liquid in the upper layer of the main oil tank 1 to enter the oil adsorption mechanism 3. On the other hand, it can transfer the floating oil in the liquid in the lower layer of the main oil tank 1 to the upper layer of the main oil tank 1, making it easier to use the oil adsorption mechanism 3 to absorb more floating oil. As a result, the amount of floating oil separated in the separation tank 2 at one time is larger, which can further accelerate the efficiency of oil and emulsion separation.

[0042] Meanwhile, the negative pressure generated by the driving action of the first driving mechanism 41 and / or the second driving mechanism 42 enables the floating oil adsorption mechanism 3 to continuously absorb the emulsion and floating oil in the main oil tank 1, which can realize continuous and automated liquid separation and help to realize automated production.

[0043] Optionally, as shown in Figures 2-5, the oil adsorption mechanism 3 includes a funnel 31, an adsorption structure, and a flow-generating pipe 35. The funnel 31 floats on the surface of the emulsion. A first notch 311 is provided on the funnel 31 for connecting the funnel 31 and the main oil tank 1. The funnel 31 has openings at both the top and bottom. One end of the adsorption structure is connected to the first pipeline 51, and the other end is connected to the upper opening of the funnel 31. One end of the flow-generating pipe 35 is connected to the second pipeline 52, and the other end is connected to the lower opening of the funnel 31.

[0044] Specifically, the funnel 31 can be configured as a cylindrical structure with openings at both the top and bottom. The first notch 311 is located on the side wall of the funnel 31, and the funnel 31 and the flow-generating pipe 35 are connected by a contraction tube. The upper opening of the contraction tube is larger and it is connected to the lower end of the funnel 31, while the lower opening of the contraction tube is smaller and it is connected to the flow-generating pipe 35.

[0045] In this embodiment, the oil adsorption mechanism 3 is configured as a funnel 31, an adsorption structure, and a flow-generating pipe 35. When the second drive mechanism 42 is activated, the upper end of the flow-generating pipe 35 near the lower end of the funnel 31 generates suction, which can drive the liquid in the main oil tank 1 to flow into the funnel 31. Then, the first drive mechanism 41 is activated, and the lower end of the adsorption structure near the upper end of the funnel 31 generates suction, which can drive the liquid in the funnel 31 to flow into the separation tank 2. Thus, by configuring the oil adsorption mechanism 3 as a funnel 31, an adsorption structure, and a flow-generating pipe 35, it is convenient to use the oil adsorption mechanism 3 to absorb the liquid in the main oil tank 1 and to transfer the liquid in the main oil tank 1 to the separation tank 2.

[0046] Optionally, as shown in Figures 2, 5, 7 and 8, the oil adsorption mechanism 3 further includes a guide ring 32. Both the funnel 31 and the guide ring 32 are cylindrical structures. The guide ring 32 is provided with a second notch 321. The guide ring 32 is located outside the funnel 31 and is used to fit with the funnel 31. The second notch 321 is used to connect with the first notch 311.

[0047] Specifically, the first notch 311 and the second notch 321 can be configured as one or more shapes such as a square, a triangle, or a V. Furthermore, the first notch 311 and the second notch 321 can be configured as structures of the same size and shape that are corresponding and connected to each other.

[0048] In this embodiment, when the first notch 311 and the second notch 321 correspond, the first notch 311 expands to its maximum size, allowing floating oil and emulsion to enter the funnel 31 through this maximized first notch 311. By rotating the guide ring 32 and the funnel 31, the first notch 311 and the second notch 321 can be misaligned, thus reducing the size of the first notch 311, allowing floating oil and emulsion to enter the funnel 31 through this reduced first notch 311. Therefore, by setting the funnel 31 and the guide ring 32, the size of the first notch 311 can be controlled, thereby controlling the content of floating oil and emulsion in the funnel 31.

[0049] Optionally, as shown in Figures 2-5, 7 and 8, multiple first notches 311 are provided, and the multiple first notches 311 are evenly distributed around the funnel 31. Multiple second notches 321 are provided, and the multiple second notches 321 are evenly distributed around the guide ring 32. The multiple first notches 311 and the multiple second notches 321 correspond one-to-one.

[0050] In this embodiment, multiple first notches 311 are provided, allowing floating oil and emulsion to enter the funnel 31 through these notches, which facilitates faster transfer and separation of the floating oil and emulsion. Simultaneously, multiple second notches 321 are provided, allowing rotation of the guide ring 32 to partially or completely correspond to the multiple first notches 311. This enables adjustment of the aperture size of the multiple first notches 311, which helps control the transfer speed of the floating oil and emulsion.

[0051] Optionally, as shown in Figure 8, both the first notch 311 and the second notch 321 are set to a V-shape.

[0052] In this embodiment, both the first notch 311 on the funnel 31 and the second notch 321 on the guide ring 32 are V-shaped. By rotating the guide ring 32, the first notch 311 and the second notch 321 are staggered, allowing the first notch 311 to gradually decrease in size and the lowest point of the V-shape to increase in height. Therefore, by making both the first notch 311 and the second notch 321 V-shaped, rotating the guide ring 32 increases the lowest point of the V-shape of the first notch 311, allowing only the floating oil on the upper layer of the emulsion to enter the first notch 311. This facilitates the transfer of a large amount of floating oil and a small amount of emulsion into the separation tank 2, improving separation efficiency.

[0053] Optionally, as shown in Figures 7 and 8, the openings of the first notch 311 and the second notch 321 both face upwards.

[0054] Specifically, both the first notch 311 and the second notch 321 are V-shaped, and the openings of the first notch 311 and the second notch 321 both face upwards.

[0055] In this embodiment, both the first notch 311 and the second notch 321 are V-shaped, and both face upwards. Rotating the guide ring 32 causes multiple smaller V-shaped notches to appear on the funnel 31 when the first notch 311 and the second notch 321 partially align, and multiple larger V-shaped notches to appear on the funnel 31 when all the first notches 311 and the second notch 321 align. Since the flow rate at the bottom of the V-shaped notch is relatively low, and considering the stratification of floating oil and emulsion within the main oil tank 1, more floating oil and less emulsion can enter the funnel 31. This further improves the separation effect.

[0056] Optionally, as shown in Figure 6, the oil adsorption mechanism 3 further includes a filler 313. A cavity 312 is provided below the funnel 31. The filler 313 is used to be placed in the cavity 312 and to adjust the draft of the funnel 31.

[0057] Specifically, one or more cavities 312 can be provided below the funnel 31. The filling material 313 can be a sponge, weight, etc. The opening of the cavity 312 faces downward, and the funnel 31 also includes a cover plate 36, which is configured as a disc-shaped annular structure. The filling material 313 is placed inside the cavity 312 and is bolted to the funnel 31 using the cover plate 36.

[0058] In this embodiment, a cavity 312 is provided on the funnel 31, which can reduce the weight of the funnel 31 and increase its buoyancy, thereby facilitating the floating of the funnel 31 on the liquid surface of the main oil tank 1. At the same time, the filling material 313 is provided in the cavity 312, which can increase the weight of the funnel 31, thereby adjusting the buoyancy of the funnel 31, so as to adjust the draft of the funnel 31, so that the first notch 311 corresponds to the floating oil, so that more floating oil and less emulsion can enter the funnel 31, thereby facilitating the separation of floating oil and emulsion.

[0059] Optionally, as shown in Figures 2-4, the oil adsorption mechanism 3 further includes a guide sleeve 331 and a guide tube 332. The guide sleeve 331 is vertically arranged and fixedly connected to the funnel 31, and the guide tube 332 is vertically arranged and fixedly connected to the main oil tank 1. The guide sleeve 331 is slidably connected to the guide tube 332 in the vertical direction.

[0060] Specifically, the guide sleeve 331 can be a hollow cylindrical tube open at both ends, and the guide tube 332 can be a solid cylinder, with the guide sleeve 331 fitted onto the guide tube 332. As shown in Figure 9, the cover plate 36 also has an installation port 361 opposite to the guide sleeve 331.

[0061] In this embodiment, when the liquid level of the emulsion in the main oil tank 1 changes, the floating adsorption structure 34 will change accordingly. Specifically, the funnel 31 and the guide ring 32 will synchronously change height in the vertical direction as the liquid level changes. Since the guide sleeve 331 is slidably connected to the guide tube 332 in the vertical direction, the guide sleeve 331 and the guide tube 332 can guide the funnel 31 to limit the movement trajectory of the funnel 31, that is, limit the funnel 31 to move only in the vertical direction, which can prevent the funnel 31 from moving in the horizontal direction. Therefore, by setting the guide sleeve 331 and the guide tube 332, and the guide sleeve 331 is slidably connected to the guide tube 332 in the vertical direction, the funnel 31 can only move in the vertical direction, which can avoid driving the adsorption structure 34 to move horizontally as a whole, thereby avoiding the disconnection between the adsorption structure 34 and the first pipeline 51, which is beneficial to transferring the floating oil and emulsion to the separation tank 2.

[0062] Optionally, as shown in Figure 2, the adsorption structure 34 includes an adsorption tube 341, a guide rail 342, and a slider 343. The guide rail 342 is vertically arranged and detachably connected to the flow guide ring 32. The slider 343 is slidably connected to the guide rail 342 in the vertical direction. The adsorption tube 341 is detachably connected to the slider 343. One end of the adsorption tube 341 is connected to the first pipeline 51, and the other end is inserted into the liquid surface from the upper opening of the funnel 31.

[0063] Specifically, as shown in Figure 10, the guide rail 342 is configured as a long strip structure, and a track 3421 is also provided on the guide rail 342, which is vertically arranged. Meanwhile, the adsorption tube 341 is L-shaped and may include a first connecting tube and a second connecting tube. The first connecting tube is horizontally arranged, and the second connecting tube is vertically arranged. One end of the first connecting tube is connected to the first pipeline 51, and the other end is connected to the upper end of the second connecting tube. The lower end of the second connecting tube is located below the liquid surface in the funnel 31. Two sliders 343 are provided, each with a semi-circular groove, and they are arranged opposite each other. The first connecting tube is placed between the two sliders 343, and the two sliders 343 are connected using bolts. The slider 343 closer to the track is slidably connected to the track. A mounting part 344 is welded onto the guide ring 32. A mounting hole 3422 is provided at the lower end of the guide rail 342, and bolts are used to connect the guide rail 342 to the mounting part 344 through the mounting hole 3422.

[0064] In this embodiment, the adsorption structure 34 consists of an adsorption tube 341, a guide rail 342, and a slider 343. The adsorption tube 341 adsorbs floating oil, and by driving the slider 343 to slide on the guide rail 342, the adsorption tube 341 can move synchronously in the vertical direction. This allows the lower end of the adsorption tube 341 to be positioned precisely within the floating oil layer, facilitating the adsorption of a large amount of floating oil and a small amount of emulsion. Therefore, by adjusting the height of the adsorption tube 341, the amount of floating oil and emulsion adsorbed by the adsorption tube 341 can be controlled, which is beneficial for the separation of floating oil and emulsion.

[0065] Optionally, as shown in Figure 1, the oil spill treatment device further includes a first liquid component detection instrument 21 and a second liquid component detection instrument 22. The first liquid component detection instrument 21 and the second liquid component detection instrument 22 are located on the upper and lower sides of the separation tank 2, respectively, and both are used to detect the conductivity of the liquid in the separation tank 2.

[0066] Specifically, the oil spill treatment device also includes a third pipeline 53, a fourth pipeline 54, a drain valve 71, an emulsion discharge valve 72, and a waste liquid tank 6. One end of the third pipeline 53 is connected to the lower end of the separation tank 2, and the other end is connected to the waste liquid tank 6. The drain valve 71 is installed on the third pipeline 53. One end of the fourth pipeline 54 is connected to the separation tank 2, and the other end is connected to the main oil tank 1. The emulsion discharge valve 72 is installed on the fourth pipeline 54.

[0067] In this embodiment, when the liquid level in the separation tank 2 reaches the level of the first liquid component detection instrument 21, the conductivity of the liquid is detected using the first liquid component detection instrument 21. If the conductivity exceeds the set value, it indicates that the emulsion content is high. Therefore, the emulsion discharge valve 72 is opened and the drain valve 71 is closed, transferring the emulsion from the separation tank 2 to the main oil tank 1. When the liquid level in the separation tank 2 reaches the level of the second liquid component detection instrument 22, the conductivity of the liquid is detected using the second liquid component detection instrument 22. If the conductivity is lower than the set value, it indicates that the floating oil content is high. Therefore, the drain valve 71 is opened and the emulsion discharge valve 72 is closed, transferring the floating oil to the waste liquid tank 6. Thus, by setting the first liquid component detection instrument 21 and the second liquid component detection instrument 22, the emulsion content in the separation tank 2 can be detected, allowing for the control of opening the emulsion discharge valve 72 and the drain valve 71 as needed, which is beneficial for separating the floating oil and emulsion in the separation tank 2. Both the emulsion discharge valve 72 and the drain valve 71 can be configured as electrically controlled valves, which can be automatically controlled as needed to achieve continuous and automated liquid separation, thus facilitating automated production.

[0068] Optionally, as shown in Figure 1, the oil spill treatment device further includes a liquid level detection instrument 23, which is installed on the separation tank 2 and is used to detect the height of the liquid level inside the separation tank 2.

[0069] Specifically, the liquid level detection instrument 23 is installed at the upper end of the separation tank 2.

[0070] In this embodiment, a liquid level detection instrument 23 is installed on the separation tank 2 to detect the height of the liquid level inward. When the liquid level reaches the set value, the pneumatic diaphragm pump can be controlled to shut down to prevent the floating oil and emulsion from being transferred into the separation tank 2, thereby preventing the leakage of floating oil and emulsion in the separation tank 2.

[0071] Optionally, the oil spill treatment device also includes a level sight glass, which is installed on the separation tank 2 and used to observe the height of the liquid level inside the separation tank 2.

[0072] In this embodiment, a liquid level sight glass is provided, which allows observation of changes in the liquid level inside the separation tank 2. This enables manual control of the drain valve 71, the emulsion discharge valve 72, and the pneumatic diaphragm pump. When the first liquid component detection instrument 21, the second liquid component detection instrument 22, and the liquid level detection instrument 23 are damaged, manual operation can be used to control the drain valve 71, the emulsion discharge valve 72, and the pneumatic diaphragm pump.

[0073] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
