[0032] As Figure 1 , Figure 4 and Figure 5 shown, the present application provides a separation device for separating the aqueous phase substance and the oil phase substance in a mixed liquid. The embodiments of the separation device of the present application include: a separation tank 10, a liquid inlet structure 20, a partition structure 30, an aqueous phase liquid outlet structure 40, an oil phase liquid outlet structure 50, and a bubble generator 60; the separation tank 10 has a separation chamber 11; the liquid inlet structure 20 is arranged on the separation tank 10 and communicates with the separation chamber 11 to input the mixed liquid into the separation chamber 11; the partition structure 30 is arranged in the separation chamber 11 and is located below the liquid inlet structure 20. The partition structure 30 includes a plurality of partitions 31 arranged at intervals in the vertical direction and extending in the horizontal direction. A plurality of flow holes are provided on the partitions 31. The plurality of partitions 31 include a first partition 311 and a second partition 312 arranged adjacent to each other. There is a first flow gap 32 between the first partition 311 and the inner surface of the separation tank 10, and there is a second flow gap 33 between the second partition 312 and the inner surface of the separation tank 10. The projections of the first flow gap 32 and the second flow gap 33 on the horizontal plane partially overlap or do not overlap; the aqueous phase liquid outlet structure 40 is arranged on the separation tank 10 and communicates with the separation chamber 11; the oil phase liquid outlet structure 50 is arranged on the separation tank 10 and communicates with the separation chamber 11; the bubble generator 60 is arranged in the separation chamber 11 and is located below the partition structure 30.

[0033] Applying the technical solution of this embodiment, the separation tank 10 provides an installation basis for each component of the separation device. The liquid inlet structure 20 is arranged on the separation tank 10 and communicates with the separation chamber 11 to input the mixed liquid into the separation chamber 11. The partition structure 30 is arranged in the separation chamber 11 and is located below the liquid inlet structure 20. The partition structure 30 can separate the aqueous phase material and the oil phase material in the mixed liquid. The aqueous phase liquid outlet structure 40 can discharge the separated aqueous phase material from the separation chamber 11, and the oil phase liquid outlet structure 50 can discharge the separated oil phase material from the separation chamber 11. Specifically, the partition structure 30 includes a plurality of partitions 31 arranged at intervals in the vertical direction and extending in the horizontal direction. A plurality of flow holes are arranged on the partitions 31. The bubble generator 60 is arranged in the separation chamber 11 and is located below the partition structure 30. The bubble generator 60 can generate a large number of bubbles. The mixed liquid flows downward through the plurality of partitions 31, and the bubbles move upward. The bubbles will adhere to the oil phase material in the mixed liquid and combine with it to form oil dregs with a density less than that of the aqueous phase material. The oil dregs can pass through the flow holes and then move upward in the separation chamber 11, thereby realizing the separation of the aqueous phase material and the oil phase material. More specifically, the plurality of partitions 31 include a first partition 311 and a second partition 312 arranged adjacent to each other. There is a first flow gap 32 between the first partition 311 and the inner surface of the separation tank 10, and there is a second flow gap 33 between the second partition 312 and the inner surface of the separation tank 10. The projections of the first flow gap 32 and the second flow gap 33 on the horizontal plane partially overlap or do not overlap. With such a setting, it can make the flow path of the mixed liquid longer when it flows through the first partition 311, the first flow gap 32, the second partition 312, and the second flow gap 33, so that the bubbles can fully contact the oil phase material in the mixed liquid, thereby ensuring the oil removal effect of the separation device and making the oil removal effect of the separation device better. Therefore, the technical solution of this embodiment can effectively solve the problem of poor oil removal effect in the related art.

[0034] As Figure 5 shown, the separation tank 10 includes a first side plate 12 and a second side plate 13 arranged opposite to each other. The first flow gap 32 is formed between the first side plate 12 and the first partition 311, and the second flow gap 33 is formed between the second side plate 13 and the second partition 312. Specifically, in this embodiment, the separation tank 10 is of a cuboid structure. With the above setting, it can make the distance between the first flow gap 32 and the second flow gap 33 in the horizontal direction relatively far, so that an S-shaped flow path is formed between the first partition 311 and the second partition 312, so that the flow path of the mixed liquid is longer, and further ensuring that the oil phase material can fully contact the bubbles, thereby ensuring the oil removal effect of the separation device.

[0035] As Figure 5As shown, the multiple partition plates 31 include multiple first partition plates 311 and multiple second partition plates 312. In the vertical direction, the first partition plates 311 and the second partition plates 312 are arranged alternately. Specifically, during the process of the mixture flowing from top to bottom, it can flow through the above-mentioned S-shaped flow path, further making the flow path of the mixed liquid longer, and thus ensuring that the oil-phase substance can fully contact the bubbles.

[0036] As Figure 3 and Figure 5 shown, the liquid inlet structure 20 includes a liquid inlet pipe 21, and the projection of the liquid inlet pipe 21 on the horizontal plane overlaps at least partially with the topmost partition plate 31. Specifically, in this embodiment, the first flow-through gap 32 is close to the first side plate 12, and the liquid inlet pipe 21 is close to the second side plate 13. Compared with the scheme where the liquid inlet pipe 21 is directly arranged at the first flow-through gap 32, this embodiment can make the mixed liquid flow through a certain distance after flowing out of the liquid inlet pipe 21 and then flow down from the first flow-through gap 32, so that the mixed liquid can contact the bubbles after flowing out of the liquid inlet pipe 21 and then flow down from the first flow-through gap 32, which also has the effect of ensuring that the oil-phase substance can fully contact the bubbles.

[0037] In addition, in this embodiment, in each partition plate 31, the ratio of the total area of the multiple flow-through holes to the area of the partition plate 31 is greater than or equal to 28:100 and less than or equal to 35:100. Specifically, meeting the above requirements can, on the one hand, enable smaller oil droplets to converge into larger sizes below the partition plate 31 and then flow upward through the flow-through holes under greater buoyancy, so that the smaller oil droplets will not stay below the partition plate 31, avoiding the situation where due to too many openings, although the smaller oil droplets pass through the flow-through holes, they stay in the middle of the separation chamber 11 due to insufficient buoyancy. On the other hand, it can also avoid the situation where it is difficult for oil droplets to pass through the partition plate 31 due to too few openings. The ratio of the total area of the multiple flow-through holes to the area of the partition plate 31 can be 28:100, 29:100, 30:100, 32:100, or 35:100; the multiple flow-through holes can be arranged on the partition plate 31 in an array manner, and the multiple flow-through holes can also be arranged in a way that two adjacent rows or two columns of flow-through holes are arranged in a staggered manner.

[0038] As Figure 3 , Figure 4 and Figure 6As shown, the aqueous phase outlet structure 40 has an aqueous phase channel 41. The aqueous phase channel 41 communicates with the separation chamber 11. The aqueous phase outlet structure 40 further includes an aqueous phase outlet member 42 and a liquid level adjusting member 43. The aqueous phase outlet member 42 is disposed on the separation tank 10 and communicates with the aqueous phase channel 41. The liquid level adjusting member 43 is movably disposed in the aqueous phase channel 41 to adjust the liquid level height of the aqueous phase substance. With such a setting, the staff can adjust the liquid level height of the aqueous phase substance by adjusting the position of the liquid level adjusting member 43, and further adjust the liquid level height of the oil phase substance, which is beneficial to the oil phase outlet structure 50 to discharge the oil phase substance from the separation chamber 11.

[0039] As Figure 3 , Figure 4 and Figure 6 As shown, the aqueous phase outlet structure 40 includes a first baffle 44. The first baffle 44 extends in the vertical direction. The lower end of the first baffle 44 is spaced from the separation tank 10. The first baffle 44 and the inner surface of the separation tank 10 form the aqueous phase channel 41. Specifically, the first baffle 44 includes a first plate body and a second plate body that extend vertically and are angled. The first baffle 44 is disposed at the corner of the separation tank 10, so as to form the aqueous phase channel 41 with the inner surface of the separation tank 10 (specifically, in this embodiment, the aqueous phase channel 41 is a channel with a rectangular cross-section formed between the first plate body, the second plate body, and two adjacent inner surfaces of the separation tank 10). The liquid level of the aqueous phase substance in the aqueous phase channel 41 is kept consistent with the liquid level of the aqueous phase substance in the separation chamber 11. Of course, in other embodiments, the aqueous phase channel can also be formed at other positions in the separation tank, as long as the above effects can be achieved.

[0040] As Figure 3 , Figure 4 and Figure 6As shown, the aqueous phase liquid outlet structure 40 includes a second baffle 45. The liquid level adjusting member 43 includes a water outlet pipe 431. The second baffle 45 is arranged between the first baffle 44 and the inner surface of the separation tank 10. The water outlet pipe 431 is connected to the second baffle 45 through a threaded structure. The upper end of the water outlet pipe 431 is provided with a liquid outlet 432. The liquid outlet 432 is located above the second baffle 45. The aqueous phase liquid outlet member 42 is communicated with the aqueous phase channel 41 located above the second baffle 45. Specifically, the second baffle 45 divides the aqueous phase channel 41 into an upper chamber and a lower chamber that are isolated from each other. The lower chamber is communicated with the separation chamber 11. The arrangement of the water outlet pipe 431 can communicate the upper chamber and the lower chamber. The upper end of the water outlet pipe 431 is provided with a liquid outlet 432. The liquid outlet 432 is located above the second baffle 45, that is, the liquid outlet 432 is located in the upper chamber. It should be noted that no matter how the water outlet pipe 431 moves, the liquid outlet 432 is always located in the upper chamber. The position of the lower edge of the liquid outlet 432 is the liquid level of the aqueous phase substance in the aqueous phase channel 41, that is, the liquid level of the aqueous phase substance in the separation chamber 11. In addition, an operation window communicated with the separation chamber 11 is also arranged on the separation tank 10. The operation window is correspondingly arranged with the water outlet pipe 431. A handle structure is also arranged on the water outlet pipe 431 to facilitate the staff to rotate the water outlet pipe 431, so as to adjust the height of the lower edge of the liquid outlet 432.

[0041] As Figures 2 to 5 shown, the oil phase liquid outlet structure 50 has an oil phase channel 51. The oil phase channel 51 is communicated with the separation chamber 11. The oil phase liquid outlet structure 50 further includes an oil phase liquid outlet member 52. The oil phase liquid outlet member 52 is arranged on the separation tank 10 and is communicated with the oil phase channel 51. With such an arrangement, the oil phase substance can be discharged to the outside of the separation chamber 11.

[0042] As Figures 2 to 5 shown, the oil phase liquid outlet structure 50 includes a third baffle 53. The third baffle 53 and the inner surface of the separation tank 10 form an oil phase channel 51. The oil phase channel 51 is a trough structure with an upward opening. Specifically, the third baffle 53 includes a third plate body and a fourth plate body. The third plate body is a vertical plate and is arranged parallel to the side plate of the separation tank 10. The fourth plate body is connected between the third plate body and the side plate of the separation tank 10 to form an oil phase channel 51 (the fourth plate body is the bottom wall of the oil phase channel 51). When the liquid level of the oil phase substance is higher than the upper surface of the third plate body, part of the oil phase substance will overflow the third plate body and enter the oil phase channel 51, and then be discharged.

[0043] In addition, the bottom wall of the oil phase channel 51 is inclined downward in the direction close to the oil phase liquid outlet member 52. That is to say, the fourth plate body is inclined downward in the direction close to the oil phase liquid outlet member 52, which is beneficial to the oil phase substance flowing in the oil phase channel 51 towards the oil phase liquid outlet member 52. The inclination angle of the fourth plate body is between 2° and 5°.

[0044] In addition, asFigure 4 and Figure 5 As shown in Figure 5 , the bubble generator 60 includes an air inlet pipe and a plurality of bubble generating parts communicated with the air inlet pipe. A plurality of air holes are arranged on the upper surface of the bubble generating parts. When gas enters each bubble generating part from the air inlet pipe and then flows out through the air holes, dense and rich bubbles are formed.

[0045] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0046] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure of the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "beneath other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations should be made for the spatial relative descriptions used here.

[0047] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meanings. Therefore, it should not be construed as a limitation to the protection scope of the present invention.

[0048] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
