Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation, and in particular to a turbid water stratification separation device for oil refining production. Background Art

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figures 1 to 12As shown: a turbid water stratification separation device for oil refining production, including a separation tank 1, a floating island structure 2 and an oil collection structure 3; the separation tube includes a rectangular tank body 11, and a liquid inlet 111 is opened on the rectangular tank body 11. The height of the liquid inlet 111 is lower than the lowest height of the floating island structure 2 in the rectangular tank body 11, and an arc-shaped baffle 12 for guiding the downward flow of the floating water is arranged at the liquid inlet 111; the floating island structure 2 includes a floating platform 21, and the floating platform 21 floats in the rectangular tank body 11 by the buoyancy of the floating water. The middle part of the floating platform 21 is hollowed out, and a gantry 22 is arranged on the upper end of the floating platform 21, and the gantry 22 is horizontally arranged above the hollow part; the oil collection structure 3 includes a first oil collection box 31, and the inner cavity of the first oil collection box 31 gradually shrinks from top to bottom to facilitate the collection of oil, and both ends of the first oil collection box 31 are provided with There is a second guide structure 32, which includes a horizontal slide 321. The horizontal slide 321 drives the first oil collection box 31 to rise and fall in the vertical direction. The second guide structure 32 also includes a first connecting plate 322 and two second guide columns 323. The middle part of the first connecting plate 322 is connected to the gantry 22. The two second guide columns 323 are respectively vertically arranged at both ends of the first connecting plate 322. The two ends of the horizontal slide 321 are respectively slidably connected to the two second guide columns 323. A downward pressure structure 33 is provided on the two horizontal slides 321. The downward pressure structure 33 includes a downward pressure block 331. The downward pressure block 331 applies a downward force to the first oil collection box 31. An oil transfer structure 34 is provided inside the first oil collection box 31. The oil transfer structure 34 is used to transfer the oil collected in the first oil collection box 31.

[0035] During the oil refining production process, the sluicing water is injected into the rectangular tank body 11 from the liquid inlet 111. As the water level of the sluicing water in the rectangular tank body 11 rises, the sluicing water provides an upward buoyancy to the first oil collection box 31. The first oil collection box 31 is hollow inside, which makes the upper end of the first oil collection box 31 much higher than the liquid level of the sluicing water. The two pressing blocks 331 apply the same vertical downward force to the two ends of the first oil collection box 31, so that the force of the first oil collection box 31 is balanced. At the same time, the two second guide structures 32 provide a guiding effect on the first oil collection box 31. The two pressing blocks 331 press the first oil collection box 31 into the sluicing water and keep the upper end of the first oil collection box 31 slightly higher than the liquid level of the sluicing water. As the amount of sluicing water injected into the rectangular tank body 11 increases, the floating platform 21 and the first At the same time, an oil collection box 31 rises with the rising water. Since the buoyancy exerted by the oil on the first oil collection box 31 is limited, the height difference between the upper end of the first oil collection box 31 and the interface between the oil and the rising water remains unchanged, and the total amount of oil in the rectangular tank body 11 is also increasing. The thicker the oil layer, the more the oil layer will gradually pass over the upper end of the first oil collection box 31 and converge toward the inner bottom of the first oil collection box 31. Then the oil transfer structure 34 collects and transfers the oil in the first oil collection box 31 out of the separation device. Since the floating platform 21 and the first oil collection box 31 change their own heights synchronously with the change in the rising water volume, only oil can enter the first oil collection box 31, thereby effectively preventing the rising water from mixing into the oil layer and entering the first oil collection box 31, thereby improving the separation efficiency.

[0036] Reference Figure 5 , Figure 6 and Figure 7 As shown: the downward pressure structure 33 also includes a mounting seat 332 and a pressure adjustment structure 333; the mounting seat 332 is fixed on the horizontal slide 321, and at least two third guide columns 3321 parallel to each other are vertically arranged on the mounting seat 332, and the two ends of the downward pressure block 331 are slidably connected with the two third guide columns 3321; the pressure adjustment structure 333 is arranged on the gantry 22, and the pressure adjustment structure 333 is used to adjust the downward pressure force of the downward pressure block 331 on the first oil collection box 31, and the pressure adjustment structure 333 includes a roller 3331, a pull rope 3332 and an insertion rod 3333, the roller 3331 is fixed on the gantry 22, the pull rope 3332 bypasses the horizontal section and the vertical section of the roller 3331, the vertical section of the pull rope 3332 is connected to the upper end of the insertion rod 3333, and the lower end of the insertion rod 3333 is inserted into the middle part of the downward pressure block 331 and connected to the downward pressure block 331.

[0037] As the amount of oil entering the first oil collection box 31 increases, the vertical downward force on the first oil collection box 31 will gradually become greater than the buoyancy on the first oil collection box 31, causing the first oil collection box 31 to gradually descend, and the upper end of the first oil collection box 31 will gradually approach the interface between the oil and the water, or even be lower than the interface, which can easily cause the water to enter the first oil collection box 31. By providing a mounting seat 332 and a pressure adjustment structure 333, the lower pressing block 331 is placed on the mounting seat 332, and the downward force applied by the lower pressing block 331 to the first oil collection box 31 remains unchanged. When an oil collection box 31 is subjected to a vertical downward force, the pressure adjustment structure 333 works, and the force applied to the lower pressure block 331 is adjusted by adjusting the tension of the horizontal section of the pull rope 3332. As the amount of oil collected increases, the downward force of the lower pressure block 331 on the first oil collection box 31 can be gradually reduced by increasing the tension on the horizontal section of the pull rope 3332, thereby maintaining a constant distance between the upper end of the collection box and the interface between the oil and the liquid, thereby achieving stable control of the first oil collection box 31 during the collection process, effectively preventing liquid from mixing into the oil collection box, and improving the purity and efficiency of oil collection.

[0038] Reference Figure 6 and Figure 7 As shown: the pressing structure 33 also includes an elastic structure 334, which is arranged at one end of the pressure adjustment structure 333. The elastic structure 334 is used to keep the pressing block 331 in contact with the mounting seat 332 when adjusting the pressing force of the pressing block 331. The elastic structure 334 includes a sleeve 3342, a pull rod 3341 and a third spring 3343. One end of the sleeve 3342 is coaxially connected to the horizontal section of the pull rope 3332, the pull rod 3341 is inserted in the sleeve 3342, the third spring 3343 is sleeved on the outside of the sleeve 3342, and the two ends of the third spring 3343 are respectively connected to the end of the sleeve 3342 and the end of the pull rod 3341.

[0039] When the force acting on the pull rope 3332 increases to a state close to its taut state, if the pulling force continues to increase, the downward pressure block 331 may be separated from the mounting seat 332, thereby losing the downward pressure on the first oil collection box 31. After the elastic structure 334 is introduced, even if the pull rope 3332 can no longer be stretched, the compression of the third spring 3343 can absorb the additional pulling force, ensuring that the downward pressure block 331 maintains contact with the mounting seat 332, ensuring that during the entire oil collection process, the downward pressure block 331 can apply a stable and continuous downward pressure to the first oil collection box 31, thereby maintaining an appropriate distance between the collection box and the interface between the oil and the liquid.

[0040] Reference Figure 5 , Figure 8 and Fig. 9As shown: the oil transfer structure 34 includes a horizontal hanging plate 341, an extraction structure 342 and a lifting structure 343; the two ends of the horizontal hanging plate 341 are respectively connected to the two second guide structures 32; the extraction structure 342 is arranged below the horizontal hanging plate 341, and the extraction structure 342 includes an extraction pipe 3421, the extraction pipe 3421 is arranged horizontally, a plurality of extraction heads 3422 are arranged at the lower end of the extraction pipe 3421, an extraction head 3422 is arranged at the upper end of the extraction pipe 3421, and lifting shafts 3424 are vertically arranged at both ends of the extraction pipe 3421, and the upper end of the lifting shaft 3424 passes through the horizontal hanging plate 341 upwards; the lifting structure 34 The lifting structure 343 is arranged at the upper end of the horizontal hanging plate 341, the lifting structure 343 is connected with the two lifting shafts 3424, and the lifting structure 343 is used to simultaneously drive the two lifting shafts 3424 to move up and down, the lifting structure 343 includes four driving plates 3431, two connecting shafts 3432 and two moving blocks 3433, the four driving plates 3431 are respectively arranged at the two ends of the two lifting shafts 3424, the two ends of the connecting shaft 3432 are respectively connected with the two driving plates 3431 on the same side of the two lifting shafts 3424, the two moving blocks 3433 are respectively arranged at the middle of the two connecting shafts 3432, and the two moving blocks 3433 can move closer to or farther from each other.

[0041] The horizontal hanging plate 341, the extraction structure 342 and the lifting structure 343 are all structures symmetrically arranged about the center of the floating platform 21, so that the forces at various locations of the floating platform 21 are balanced. The first oil collection box 31 is deep. If the oil in the deepest part of the first oil collection box 31 is to be extracted, the extraction structure 342 needs to be inside the first oil collection box 31, which will cause the oil to adhere to the extraction structure 342. By setting the lifting structure 343, in the initial state, the extraction structure 342 is located above the first oil collection box 31, and the two moving blocks 3433 drive The two connecting shafts 3432 move away from each other, and the two connecting shafts 3432 drive the two driving plates 3431 on both sides of the lifting shaft 3424 to move, so that the angle between the two driving plates 3431 increases, and the connection between the two driving plates 3431 moves toward the horizontal lifting plate 341. As the oil level in the first oil collecting box 31 decreases, the two lifting shafts 3424 gradually move toward the first oil collecting box 31 at the same time, so that the extraction tube 3421 translates toward the first oil collecting box 31, thereby ensuring that the extraction head 3422 is always inserted below the oil level.

[0042] Reference Fig. 9 As shown, the oil transfer structure 34 also includes four fourth springs 344 , which are respectively arranged on the four corners of the horizontal hanging plate 341 , and the two ends of the fourth spring 344 are respectively connected to the horizontal hanging plate 341 and the horizontal sleeve 232 .

[0043] When the extraction structure 342 extracts oil from the first oil collection box 31, as the amount of oil decreases, the downward pressure on the first oil collection box 31 decreases rapidly, and it may rise rapidly. By providing four fourth springs 344, the four fourth springs 344 are respectively mounted on the four second guide columns 323. When the first oil collection box 31 rises due to the reduction of oil, the first oil collection box 31 will interact with the fourth springs 344 through the horizontal sleeve 232, driving the entire horizontal lifting plate 341 to move horizontally upward, and the horizontal lifting plate 341 drives the extraction structure 342 and the lifting structure 343 to move synchronously as a whole, thereby ensuring the stability of the relative position between the extraction structure 342 and the first oil collection box 31 during the extraction process, thereby improving the accuracy and safety of the operation.

[0044] Reference Figure 3 , Figure 4 and Fig.10 As shown: the oil collection structure 3 also includes a second oil collection box 35 and a guide cover plate 36; the second oil collection box 35 is arranged inside the first oil collection box 31, and there is a gap between the second oil collection box 35 and the first oil collection box 31; the guide cover plate 36 is arranged at the upper end of the first oil collection box 31, the guide cover plate 36 covers the gap between the first oil collection box 31 and the second oil collection box 35, and the guide cover plate 36 extends to the inside of the second oil collection box 35, and the surface of the guide cover plate 36 is provided with an inclined surface inclined toward the inside of the second oil collection box 35.

[0045] In actual application, most of the first oil collection tank 31 is immersed in the swirling water. In the process of continuously collecting oil, the swirling water will inevitably be introduced, causing the swirling water in the rectangular tank body 11 to shake, which may then cause the first oil collection tank 31 to shake as well, and then collide with the extraction structure 342. By providing the second oil collection tank 35 and the guide cover plate 36, the gap between the second oil collection tank 35 and the first oil collection tank 31 can prevent the first oil collection tank 31 from colliding with the second oil collection tank 35. The influence of external disturbance on the collection process of the second oil collection tank 35 is effectively isolated. The guide cover plate 36 is installed at the upper end of the first oil collection tank 31, which not only covers the gap between the first oil collection tank 31 and the second oil collection tank 35, but also guides the oil to flow smoothly into the second oil collection tank 35 through the inclined slope on its surface. The extraction structure 342 extracts oil from the second oil collection tank 35 in a stable state, thereby avoiding the extraction structure 342 from colliding with the shaking first oil collection tank 31.

[0046] Reference Figure 4 , Figure 6 and Fig.11As shown: the oil collection structure 3 also includes a shock-absorbing connection structure 37, which has two shock-absorbing connection structures 37. The two shock-absorbing connection structures 37 are respectively arranged at the two ends of the first oil collection box 31, and the shock-absorbing connection structure 37 includes a vertical connecting plate 371 and a first buffer structure 372; the vertical connecting plate 371 is arranged between the horizontal slide 321 and the first oil collection box 31; the first buffer structure 372 is arranged at the upper end of the vertical connecting plate 371, and the first buffer structure 372 hoists the vertical connecting plate 371 below the horizontal slide 321, and the first buffer structure 372 includes at least two horizontally arranged first guide rods 3721, and the two first guide rods 3721 are arranged in parallel, the upper end of the vertical connecting plate 371 is slidably connected to the two first guide rods 3721, and the two first guide rods 3721 can keep the vertical connecting plate 371 translated along the first guide rods 3721, and both ends of the first guide rods 3721 are sleeved with fifth springs 3722.

[0047] Although the shaking of the first oil collection box 31 will not be directly transmitted to the second oil collection box 35, the first oil collection box 31 will be transmitted to the oil transfer structure 34 through the second guide structure 32. By setting the first buffer structure 372, when the shaking of the water causes the first oil collection box 31 to be subjected to a force along the axial direction of the first guide rod 3721, the first oil collection box 31 moves along the first guide rod 3721, and will compress or stretch the fifth springs 3722 on both sides. The elastic deformation process of the fifth spring 3722 absorbs and disperses the action of the external force, so that the vibration received by the first oil collection box 31 along the direction of the first guide rod 3721 will not be transmitted to the second guide structure 32.

[0048] Reference Figure 6 and Fig.11 As shown: the shock-absorbing connection structure 37 also includes a second buffer structure 373, which is arranged at the lower end of the vertical connecting plate 371. The second buffer structure 373 is used to connect the vertical connecting plate 371 and the first oil collection box 31. The second buffer structure 373 includes a plurality of second guide rods 3731, and the plurality of second guide rods 3731 are arranged parallel to each other. One end of the second guide rod 3731 is connected to the first oil collection box 31, and the other end of the second guide rod 3731 is slidably connected to the vertical connecting plate 371. Each second guide rod 3731 is sleeved with a sixth spring 3732, and the two ends of the sixth spring 3732 are respectively abutted against the end of the second guide rod 3731 and the vertical connecting plate 371.

[0049] When the shaking of the water causes the first oil collection box 31 to be subjected to a force along the axial direction of the second guide rod 3731, the first oil collection box 31 moves along the second guide rod 3731, compressing or stretching the sixth spring 3732 on both sides. The elastic deformation process of the sixth spring 3732 absorbs and disperses the action of the external force, so that the vibration of the first oil collection box 31 along the direction of the second guide rod 3731 will not be transmitted to the second guide structure 32.

[0050] Reference Figure 5 and Fig.12 As shown: the floating island structure 2 also includes a first guide structure 23, which has four first guide structures 23. The four first guide structures 23 are respectively arranged at the four corners of the floating platform 21. The first guide structure 23 includes a first guide column 231, a sliding sleeve 232 and a first spring 233. The first guide column 231 is vertically arranged in the rectangular tank body 11, the sliding sleeve 232 is slidably arranged on the first guide column 231, and the sliding sleeve 232 is connected to the floating platform 21. The first spring 233 is arranged at the lower end of the floating platform 21, and the first spring 233 is sleeved on the first guide column 231.

[0051] The increase of the swamp water in the rectangular tank body 11 will cause the floating platform 21 to swing uncontrollably. The swing of the floating platform 21 will cause the first oil collection box 31 to swing greatly to the left and right. One side of the first oil collection box 31 may tilt to be lower than the interface between the oil and the swamp water, causing the swamp water to enter the oil collection structure 3. By setting four first guide structures 23, in the initial state, the four corners of the floating platform 21 are respectively in contact with the four first springs 233 through the sliding sleeves 232, so that the floating platform 21 is higher than the liquid inlet 111 as a whole, ensuring the safety of the oil collection structure 3. When the swamp water level in the rectangular tank body 11 rises, the floating platform 21 rises due to the buoyancy. During the rising process, the four first guide columns 231 limit the horizontal movement of the floating platform 21, ensuring that the floating platform 21 rises steadily in the vertical direction, thereby protecting the oil collection structure 3 from the invasion of swamp water.

[0052] Reference Figure 3 As shown, an overflow port 112 is also provided on the rectangular tank body 11 , and the height of the overflow port 112 is lower than the maximum height that the floating platform 21 can reach.

[0053] The height of the rectangular tank body 11 is limited. When the floating platform 21 rises to the highest position, if the wet water continues to be injected into the rectangular tank body 11, the wet water will exceed the first oil collection box 31. By opening an overflow port 112 on the rectangular tank body 11, when the height of the oil layer does not exceed the overflow port 112, the overflow port 112 is in a closed state. When the oil layer exceeds the overflow port 112, the overflow port 112 is opened, and the overflow port 112 discharges the wet water out of the rectangular tank body 11, thereby preventing the height of the wet water in the rectangular tank body 11 from increasing, thereby preventing the wet water from overflowing the upper end of the first oil collection box 31.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
