For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0027] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature.

[0028] The present utility model provides an orientation separation device for an intermittent caustic refining process. Referring to Figure 1 and Figure 2 , in an embodiment, the orientation separation device for the intermittent caustic refining process includes: a first settling tank 2, a second settling tank 4 and a water absorption device 8. An inlet 6 and a first through hole 9 are provided in the first settling tank 2. The height of the inlet 6 is greater than that of the first through hole 9. The second settling tank 4 is provided with an outlet 83 and a second through hole 5. The second through hole 5 and the outlet 83 are arranged in a staggered manner. The height of the second through hole 5 is not lower than that of the outlet 83. The first through hole 9 communicates with the second through hole 5. The water absorption device 8 is arranged in the second settling tank 4 and is connected to the outlet 83.
[0029] Among them, in this embodiment, it is not limited that each settling tank is in an independent state, and one settling tank can also be separated into multiple settling tanks by setting baffles; the higher the height of the settling tank, the better the static separation effect of the oil-water mixture. Exemplarily, the size of each settling tank is 1.5×1.5×1.3 m, and the sizes of the first through hole 9 and the second through hole 5 are 15×8 cm; the first through hole 9 and the second through hole 5 can be connected by a water pump or a pipeline, etc., or can be directly joined as the same through hole. When the first through hole 9 and the second through hole 5 are connected by a pipeline, the height of the first through hole 9 is not lower than that of the second through hole 5, and the bottom of the second settling tank 4 is not lower than the bottom of the first settling tank 2; when the first through hole 9 and the second through hole 5 are directly joined as the same through hole, the bottoms of the first settling tank 2 and the second settling tank 4 are on the same horizontal plane, and the height of the second settling tank 4 is not lower than the height of the inlet 6.
[0030] It should be understood that in the refining of grease, alkali needs to be added to remove free fatty acids in the grease, and water is added to wash away soluble phospholipids. The alkali solution and free fatty acids will form soapstock, and thus some means are needed to separate the grease from the soapstock and water. After adding alkali and water to the oil and reacting, let it stand for a period of time, and the formed soapstock will settle at the bottom.
[0031] Specifically, the oil-water mixture is injected from the liquid inlet 6 into the first sedimentation tank 2. The oil-water mixture will move in a zigzag motion due to the height difference when flowing from the liquid inlet 6 to the first sedimentation tank 2. Since the density of water is greater than that of oil, the oil-water mixture will stratify, with water sinking and oil rising. The water at the lower layer of the first sedimentation tank 2 will first flow into the second sedimentation tank 4 through the first through-hole 9 and the second through-hole 5 communicated therewith. At the same time, since the second through-hole 5 and the liquid outlet 83 are staggered, and the height of the second through-hole 5 is greater than that of the liquid outlet 83, the liquid will flow in a second zigzag manner, and the remaining diluted oil-water mixture will further settle and separate.
[0032] In this embodiment, by setting the height difference between the liquid inlet 6 and the first through-hole 9 in the first sedimentation tank 2, the oil-water mixture first undergoes zigzag sedimentation in the directional separation device of the batch caustic refining process. At the same time, the second sedimentation tank 4 is provided to enable the oil-water mixture to flow in a second zigzag manner. The progressive zigzag sedimentation of the oil-water mixture makes the oil-water separation more thorough.
[0033] In one of the embodiments, as Figure 1 shown, the directional separation device of the batch caustic refining process further includes a third sedimentation tank 3. A third through-hole 9 and a fourth through-hole 5 are provided in the third sedimentation tank 3. The height of the third through-hole 9 is not lower than that of the fourth through-hole 5. The third through-hole 9 and the fourth through-hole 5 are arranged in a staggered manner. The third through-hole 9 is communicated with the first through-hole 9, and the fourth through-hole 5 is communicated with the second through-hole 5.
[0034] Among them, the first through-hole 9 and the third through-hole 9 can be connected by a water pump or a pipeline, etc., or can be directly joined as the same through-hole. The fourth through-hole 5 and the second through-hole 5 can be connected by a water pump or a pipeline, etc., or can be directly joined as the same through-hole. Different connection situations can refer to the above embodiments and will not be elaborated here.
[0035] It should be understood that in other embodiments, a fourth sedimentation tank and a fifth sedimentation tank, etc. may also be included. The more the number of sedimentation tanks, the better the effect of oil-water static stratification.
[0036] In this embodiment, the third sedimentation tank 3 is provided to enable the oil-water mixture to perform one more zigzag motion in the third sedimentation tank 3. The progressive zigzag sedimentation separation of the oil-water mixture through the first sedimentation tank 2, the third sedimentation tank 3, and the second sedimentation tank 4 can better complete the oil-water separation.
[0037] In one of the embodiments, as Figure 1 shown, the bottoms of the first sedimentation tank 2, the third sedimentation tank 3, and the second sedimentation tank 4 are at the same horizontal height. The height of the first through-hole 9 is not lower than that of the third through-hole 9, and the height of the fourth through-hole 5 is not lower than that of the second through-hole.
[0038] Among them, the first sedimentation tank 2, the third sedimentation tank 3, and the third sedimentation tank 3 are connected in sequence, and can be connected by pipelines or by direct fitting.
[0039] Specifically, the directional separation device of the batch alkali refining process includes: a first sedimentation tank 2, a second sedimentation tank 4, and a water absorption device 8. An inlet 6 and a first through hole 9 are provided in the first sedimentation tank 2. The height of the inlet 6 is greater than that of the first through hole 9. The second sedimentation tank 4 is provided with an outlet 83 and a second through hole 5. The second through hole 5 and the outlet 83 are arranged in a staggered manner. The height of the second through hole 5 is not lower than that of the outlet 83. The first through hole 9 communicates with the second through hole 5. The water absorption device 8 is arranged in the second sedimentation tank 4 and connected to the outlet 83. The directional separation device of the batch alkali refining process further includes a third sedimentation tank 3. A third through hole 9 and a fourth through hole 5 are provided in the third sedimentation tank 3. The height of the third through hole 9 is not lower than that of the fourth through hole 5.

The height of the first through hole 9 is not lower than that of the third through hole 9. The height of the fourth through hole 5 is not lower than that of the second through hole 5.
[0040] In this embodiment, the first sedimentation tank 2, the second sedimentation tank 4, and the third sedimentation tank 3 are connected in sequence at the same height, making the directional separation device more space-saving. The pressure in each sedimentation tank is the same, enhancing the separation effect and keeping the flow of the liquid more stable and uniform during the separation process.
[0041] In one of the embodiments, as Figure 1 shown, the first through hole 9 is in contact with the third through hole 9, the fourth through hole 5 is in contact with the second through hole 5, and the third through hole 9 and the fourth through hole 5 are equal in height and close to the bottom of the tank.
[0042] Among them, this embodiment can also be understood as the first through hole 9 and the third through hole 9 being the same through hole, the fourth through hole 5 and the second through hole 5 being the same through hole, and the first sedimentation tank 2, the third sedimentation tank 3, and the second sedimentation tank 4 being adjacent to each other and connected by fitting.
[0043] Specifically, the directional separation device of the batch alkali refining process includes: a first sedimentation tank 2, a second sedimentation tank 4, and a water absorption device 8. An inlet 6 and a first through hole 9 are provided in the first sedimentation tank 2. The height of the inlet 6 is greater than that of the first through hole 9. The second sedimentation tank 4 is provided with an outlet 83 and a second through hole 5. The second through hole 5 and the outlet 83 are arranged in a staggered manner. The height of the second through hole 5 is not lower than that of the outlet 83. The first through hole 9 communicates with the second through hole 5. The water absorption device 8 is arranged in the second sedimentation tank 4 and connected to the outlet 83. The directional separation device of the batch alkali refining process further includes a third sedimentation tank 3. A third through hole 9 and a fourth through hole 5 are provided in the third sedimentation tank 3. The height of the third through hole 9 is not lower than that of the fourth through hole 5. The third through hole 9 and the fourth through hole 5 are arranged in a staggered manner. The third through hole 9 communicates with the first through hole 9. The fourth through hole 5 communicates with the second through hole 5. The height of the first through hole 9 is not lower than that of the third through hole 9. The height of the fourth through hole 5 is not lower than that of the second through hole 5. The bottoms of the first sedimentation tank 2, the third sedimentation tank 3, and the second sedimentation tank 4 are at the same horizontal height. The first through hole 9 is in contact with the third through hole 9. The fourth through hole 5 is in contact with the second through hole 5. The third through hole 9 and the fourth through hole 5 are equal in height and close to the bottom of the tank.
[0044] In this embodiment, by arranging the third through hole 9 and the fourth through hole 5 close to the bottom of the tank, the water at the bottom of the sedimentation tank first enters the next sedimentation tank, improving the oil-water separation efficiency of the device.
[0045] In one of the embodiments, as Figure 1 and Figure 3 shown, the inlet 6 and the first through hole 9 are respectively arranged at both ends of the body diagonal of the first sedimentation tank 2. The third through hole 9 and the fourth through hole 5 are respectively arranged at both ends of the bottom diagonal of the third sedimentation tank 3. The second through hole 5 and the outlet 83 are respectively arranged at both ends of the bottom diagonal of the second sedimentation tank 4.
[0046] Among them, as Figure 3 shown by the dotted line with an arrow in, the broken-line sedimentation path of the oil-water mixture in the first sedimentation tank 2 is the body diagonal of the first sedimentation tank 2. The broken-line sedimentation path of the oil-water mixture in the third sedimentation tank 3 is the bottom diagonal of the third sedimentation tank 3. The broken-line sedimentation path of the oil-water mixture in the second sedimentation tank 4 is the bottom diagonal of the second sedimentation tank 4.
[0047] In this embodiment, by setting the broken-line sedimentation path on the various diagonals of the sedimentation tank, the broken-line flow path of the oil-water mixture in the sedimentation tank is maximized, increasing the sedimentation time and area, reducing turbulence, and enhancing the oil-water separation effect.
[0048] In one embodiment, as Figure 1 shown, the directional separation device of the batch caustic refining process further includes a two-way separation hinge 1, and the two-way separation hinge 1 is arranged at the liquid inlet 6.
[0049] It should be understood that after adding alkali and water to the oil and the reaction is completed, after standing for a period of time, the formed soap stock will settle at the bottom, and the separation of oil and water requires the soap stock to be discharged first.
[0050] Among them, the orifice of the two-way separation hinge 1 is rotatable.
[0051] Specifically, when the discharged material starts to be an oil-water mixture, align the two-way shunt orifice with the first sedimentation tank 2.
[0052] In this embodiment, by setting the two-way separation hinge 1, the separation process of oil and water is made more convenient.
[0053] In one embodiment, as Figure 1 shown, the directional separation device of the batch caustic refining process further includes a liquid storage tank 7 for storing soap stock.
[0054] It should be understood that after adding alkali and water to the oil and the reaction is completed, after standing for a period of time, the formed soap stock will settle at the bottom, and the separation of oil and water requires the soap stock to be discharged first.
[0055] Exemplarily, when the discharged material in the pipeline is soap stock, align the two-way shunt orifice with the liquid storage tank 7 for discharging, and when the discharged material starts to be an oil-water mixture, reverse the two-way shunt orifice to align with the first sedimentation tank 2 to discharge the oil-water mixture.
[0056] In one embodiment, referring to Figure 2 , the water absorption device 8 includes a first pipeline 81 and a second pipeline 82. One end of the first pipeline 81 is lower than the other end of the first pipeline 81. The second pipeline 82 is communicated with the pipe wall of the first pipeline 81. One end of the first pipeline 81 is blocked by the water in the second sedimentation tank 4.
[0057] Among them, one end of the first pipeline 81 is the inlet. One end of the first pipeline 81 being blocked by the water in the second sedimentation tank 4 means that a liquid seal is set for the first pipeline 81 in the second sedimentation tank 4.
[0058] Specifically, the bottoms of the first sedimentation tank 2, the third sedimentation tank 3, and the second sedimentation tank 4 are at the same horizontal height. When the liquid level height in the second sedimentation tank 4 reaches the connection point (bifurcation point) of the second pipe 82 and the first pipe 81, for example, the height of this connection point (bifurcation) is 1.1 m, the water in the second sedimentation tank 4 will be sucked up and discharged from the second pipe 82; when the zigzag sedimentation and static settlement of the three sedimentation tanks are completed and in equilibrium, the two-way shunt joint releases an appropriate amount of oil-water mixture into the first sedimentation tank 2. The water sedimented below the first sedimentation tank 2 enters the third sedimentation tank 3, the water below the third sedimentation tank 3 enters the second sedimentation tank 4, and the excess water below the second sedimentation tank 4 will flow into the second pipe 82 through the first pipe 81 and be discharged. The first sedimentation tank 2, the third sedimentation tank 3, and the second sedimentation tank 4 will be in equilibrium due to the same pressure.
[0059] In this embodiment, by arranging the first pipe 81 and the second pipe 82 to form a siphon device, the separated water is discharged under a stable state by using the pressure.
[0060] In one of the embodiments, the water absorption device 8 is integrally formed.
[0061] In this embodiment, the integrally formed water absorption device 8 (the first pipe 81 and the second pipe 82) can reduce the assembly process, reduce the risk of material fatigue and fracture, avoid loosening between the first pipe 81 and the second pipe 82, etc., and improve the reliability and durability of the product; in other embodiments, the first pipe 81 and the second pipe 82 can be connected by means of ferrule and bonding, etc. This connection method is more flexible, and the height of the connection point (bifurcation height) between the first pipe 81 and the second pipe 82 can be adjusted by replacing the first pipe 81.
[0062] In one of the embodiments, as Figure 2 shown, the first pipe 81 is perpendicular to the bottom of the second sedimentation tank 4, and the second pipe 82 is perpendicular to the first pipe 81.
[0063] Specifically, the water absorption device 8 includes a first pipe 81 and a second pipe 82. The first pipe 81 is perpendicular to the bottom of the second sedimentation tank 4, the second pipe 82 is communicated with the pipe wall of the first pipe 81, one end of the first pipe 81 is sealed by the water in the second sedimentation tank 4, and the second pipe 82 is perpendicular to the first pipe 81.
[0064] In this embodiment, by making the first pipe 81 perpendicular to the bottom of the second sedimentation tank 4 and the second pipe 82 perpendicular to the first pipe 81, compared with the inclined pipes, the vertical pipes reduce the manufacturing cost of the water absorption device 8 and are the simplest and best water absorption device 8 (siphon device).
[0065] In one embodiment, as Figure 2 shown, the water absorption device 8 further includes an emptying valve 84, and the emptying valve 84 is connected to the liquid outlet 83.
[0066] Specifically, when the directional separation device of the batch caustic refining process is working, the emptying valve 84 is in a closed state. When the directional separation device of the batch caustic refining process is used up, the emptying valve 84 is opened to empty the liquid in the directional separation device of the batch caustic refining process.
[0067] In one embodiment, referring to Figure 1 and Figure 3 , the directional separation device of the batch caustic refining process further includes a waste water tank, and the waste water tank is connected to the outlet of the water absorption device 8.
[0068] In this embodiment, by providing a waste water tank to receive the separated waste water, the waste water can be centrally treated. In other embodiments, the waste water tank is also connected to the emptying valve 84.
[0069] In one embodiment, the directional separation device of the batch caustic refining process further includes a vacuum pump suction pipe, and the vacuum pump suction pipe is used to suck the oil in the first sedimentation tank 2, the third sedimentation tank 3 and the second sedimentation tank 4.
[0070] In one embodiment, the first through hole 9 and the third through hole 9 are connected by a water pump, the fourth through hole 5 and the second through hole 5 are connected by a water pump, the height of the third through hole 9 is greater than that of the fourth through hole 9, and the height of the second through hole 5 is greater than that of the liquid outlet 83.
[0071] In this embodiment, the liquid inlet 6 and the first through hole 9 are respectively located at the two ends of the body diagonal of the first sedimentation tank 2, the third through hole 9 and the fourth through hole 5 are respectively located at the two ends of the body diagonal of the third sedimentation tank 3, and the second through hole 5 and the liquid outlet 83 are respectively located at the two ends of the body diagonal of the second sedimentation tank 4. In this case, the zigzag sedimentation path of the oil-water mixture in each sedimentation tank is maximized, and the oil-water separation effect is optimal.
[0072] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
