All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0029] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted.

[0030] See also Figure 1-4 The utility model provides a technical solution: a petrochemical oil-water impurity separation and processing device, comprising a separation barrel 1 with an input port and an output port respectively provided on the top surface and the side surface; a filter plate 2 for filtering impurities and a stirring mechanism for eliminating bubbles are provided between the input port and the output port in the separation barrel 1; the stirring mechanism rotates with the separation barrel 1, one end of the filter plate 2 slides with the separation barrel 1, a linkage component is provided between the filter plate 2 and the stirring mechanism, and the linkage component can drive the filter plate 2 to slide in the separation barrel 1 under the drive of the stirring mechanism.

[0031] The stirring mechanism and the filter plate 2 are installed up and down in the separation barrel 1, that is, the oil passes through the input port, the stirring mechanism and the filter plate 2 in sequence. The outer surface of the filter plate 2 is provided with a rectangular frame, which extends toward the top surface of the filter plate 2.

[0032] During use, the operator delivers a mixed solution of oil and water (hereinafter referred to as the mixed solution) into the separation barrel 1 through the input port. Under the influence of gravity, the mixed solution naturally flows downward and first contacts the stirring mechanism, which stirs the mixed solution. The shear force generated by the stirring breaks the surface tension of the bubbles, making the bubbles easier to burst. The mixed solution then flows to the filter plate 2 and filters impurities through the filter holes on the filter plate 2. The linkage component causes the filter plate 2 to slide, making it difficult for impurities on the filter plate 2 to block the filter holes on the filter plate 2, thereby allowing the mixed solution to better pass through the filter holes on the filter plate 2. The mixed solution that passes through the filter holes accumulates at the bottom of the separation barrel 1. Over time, under the influence of gravity, the density difference between water and oil is used to make the oil float on the water surface in a static state.

[0033] When the oil-water impurity separation and treatment device for petrochemical industry described in the utility model is used to treat a mixed solution, the mixed solution is stirred by the stirring mechanism, which eliminates bubbles and slows down the downward flow speed of the mixed solution. The residence time of the mixed solution after the bubbles are eliminated and the flow rate is slowed down on the filter plate 2 is prolonged, and the probability of bubbles covering the filter holes on the filter plate 2 is reduced, which increases the chance of impurities being intercepted by the filter screen, thereby improving the filtering effect. The linkage component drives the filter plate 2 to slide, reducing the situation where impurities block the filter holes on the filter plate 2, thereby improving the purity and quality of the separated petroleum.

[0034] In this embodiment, the two ends of the filter plate 2 are respectively a fixed end 201 and a movable end 202. The fixed end 201 rotates with the inner wall of the separation barrel 1, and the movable end 202 is connected to a linkage component, which can push and pull the movable end 202 up and down.

[0035] During specific use, since the linkage assembly and the rotating surface of the stirring assembly are connected at an axially misaligned position, and the linkage assembly is limited in length, when the connecting portion of the linkage assembly and the stirring assembly rotates in a direction away from the filter plate 2, the linkage assembly pulls the movable end 202 of the filter plate 2 upward.

[0036] When the linkage assembly and the connection portion of the stirring assembly rotate in a direction close to the filter plate 2 , the linkage assembly pushes the movable end 202 of the filter plate 2 downward.

[0037] In this embodiment, the stirring mechanism includes two stirring rollers 3 and two gears 4. The two gears 4 are installed on the outer wall of one side of the separation barrel 1 and are meshed with each other. The two gears 4 are coaxially connected to one end of the two stirring rollers 3 respectively. A plurality of stirring blades 301 are evenly distributed on the outer surface of the stirring roller 3 along the circumferential direction of the stirring roller 3, and one end of one of the stirring rollers 3 is connected to a drive motor 5.

[0038] Among them, the drive motor is a mature existing technology, and the model that can be used is: YE3100L-4.

[0039] During specific use, one of the stirring rollers 3 is driven to rotate by starting the driving motor 5. Since the two stirring rollers 3 are connected by two relatively meshing gears 4, the other stirring roller 3 and the two gears 4 are caused to rotate synchronously. Since the other stirring roller 3 is driven by two gears 4, the rotation directions of the two stirring rollers 3 are opposite. The two stirring rollers 3 stir the mixed solution in opposite directions. During the stirring process, the stirring blade 301 generates shear force on the mixed solution, and the stirring blade 301 itself can also break the bubbles by contacting them.

[0040] In this embodiment, a vertically extending slide groove 101 is opened on the side wall of the separation barrel 1, and the linkage assembly includes a connecting bar 6 and a connecting rod 601. The connecting rod 601 is located in the slide groove 101 and slides with the slide groove 101. The two ends of the connecting rod 601 are respectively rotatably engaged with the movable end 202 of the filter plate 2 and one end of the connecting bar 6, and the other end of the connecting bar 6 is rotatably engaged with one of the gears 4.

[0041] During specific use, since the connecting bar 6 is a rigid connecting piece, its length is not easy to change, which causes the connecting bar 6 to be driven by the gear 4 to move away from or close to the filter plate 2 during the rotation of the gear 4, and then the connecting rod 601 is driven to move synchronously through the connecting bar 6. Since the connecting bar 6 and the connecting rod 601 are rotatably connected, the connecting rod 601 is driven to move up and down in the slide groove 101, and then the movable end 202 of the filter plate 2 is driven to move up and down through the connecting rod 601, causing the filter plate 2 as a whole to flip around the fixed end 201 as the axis.

[0042] In this embodiment, the area where the filter plate 2 and the stirring mechanism are located in the separation barrel 1 is the upper chamber, and the area below the upper chamber in the separation barrel 1 is the lower chamber. The output port is connected to the side wall of the lower chamber, and a delivery pipe 7 is provided at the output port. One end of the delivery pipe 7 is connected to the lower chamber, and the other end is connected to a pump.

[0043] During specific use, the mixed solution processed by the stirring mechanism and the filter plate 2 naturally falls into the lower chamber through the upper chamber. As time goes by, under the influence of gravity, the density difference between water and oil is used to make the oil float on the water surface in a static state, thereby promoting the separation of oil and water. Then, the oil and water can be extracted separately through the delivery pipe 7 in conjunction with the pump.

[0044] In this embodiment, the conveying pipe 7 includes a transverse section and a vertical section. The ends of the transverse section and the vertical section are vertically connected. A pumping hole is opened on the side wall of the vertical section and the vertical section has a stretching performance and extends vertically.

[0045] The horizontal section and the vertical section are vertically connected to form an "L" shape, and the vertical section is a flexible pipe, such as a corrugated pipe, so that the vertical section has extensibility.

[0046] In this embodiment, a fixing piece 701 coaxial with the vertical section is provided at the lower portion of the vertical section. The fixing piece 701 is fixedly sleeved on the outer surface of the vertical section, and the diameter of the fixing piece 701 is larger than that of the vertical section.

[0047] During specific use, when the mixed solution falls downward after passing through the filter plate 2, part of the mixed solution will fall onto the top surface of the fixed plate 701. The fixed plate 701 will be pressed downward by the impact during the fall or the gravity of the accumulation, thereby driving the vertical section to extend, causing the lower part of the vertical section to be located in the mixed solution. As the oil and water gradually separate, the vertical section comes into contact with the water below. At this time, the operator can start the pump to pump out the water first, and then pump out the remaining oil.

[0048] In this embodiment, an airbag 8 is provided at the lower part of the vertical section, and an air tube 801 is provided on the top surface of the airbag 8. One end of the air tube 801 is connected to the airbag 8, and the other end passes through the side wall of the separation barrel 1 and is connected to the air pump. The air tube 801 has stretchability and can extend vertically.

[0049] During specific use, the air bag 8 is inflated by the air pump and the air pipe 801, causing the air bag 8 to float upward in the mixed solution until it floats on the top surface of the mixed solution. As the oil and water gradually separate, the vertical section contacts the oil above. At this time, the operator can start the pump to extract the oil first. As the oil decreases, the air bag 8 gradually descends along with the top surface of the oil. After the oil is pumped out, the vertical section contacts the water to extract the water.

[0050] In this embodiment, two drainage blocks 9 are respectively provided on opposite sides of the input port of the separation barrel 1, and a through opening connected to the upper chamber is formed between the two drainage blocks 9. The through opening is located directly above the two stirring rollers 3, and the top surfaces of the two drainage blocks 9 are inclined surfaces inclined downward toward the direction of the through opening.

[0051] Among them, the two drainage blocks 9 are respectively provided with grooves for accommodating the stirring roller 3 on the opposite sides. The two grooves are connected with the through-port to form a stirring chamber. The stirring chamber cooperates with the rotating stirring roller 3 to slow down the flow speed of the oil when passing through the stirring chamber.

[0052] In this embodiment, an observation window 10 is further provided on the side wall of the separation barrel 1. A transparent plate is provided in the observation window 10. The side wall of the separation barrel 1 is further provided with scale lines 11 located on one side of the observation window 10. The scale lines 11 are arranged vertically.

[0053] During specific use, the operator can view the separation progress of the mixed solution in the separation barrel 1 through the observation window 10, and can intuitively see the amount of water and mixed solution according to the scale line 11, and then the operator can calculate the ratio of oil and water in the mixed solution through a series of calculations.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
