Description

Technical Field

[0001] The utility model belongs to the technical field of oil-water separation, and specifically relates to an oil-water separator for preparing hexamethyldisiloxane. Background Art

[0002] With the rapid development of the organosilicon industry, the output of organosilicon chlorosilane monomers is also increasing. Hexamethyldisiloxane is a colorless, transparent liquid with volatile properties. It can gradually decompose in the atmosphere. It is insoluble in water but soluble in most organic solvents. Hexamethyldisiloxane is commonly used and there are many preparation methods. During the preparation process, the reaction liquid is cooled, washed, separated, and distilled under reduced pressure to finally obtain refined hexamethyldisiloxane.

[0003] In the prior art, since the preparation process of hexamethyldisiloxane requires multiple washing of the reaction solution, the resulting oil-water mixture is usually separated from the oil and water by distillation. However, the long distillation process results in a low oil-water separation efficiency, and it is not easy to fully separate and discharge the oil and water, resulting in the consumption of oil and water separation during the muscle-building preparation process.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1 , Figure 3 As shown, the utility model is an oil-water separator for preparing hexamethyldisiloxane, comprising a separation tank 1, wherein a accommodating chamber 2 is provided inside the separation tank 1, a driving assembly 3 is arranged on the top of the separation tank 1, an inlet pipe 4 is fixedly installed on one side of the separation tank 1, a guide plate 5 is provided on the inner wall of the accommodating chamber 2, and a guide port 6 is provided on the top of the guide plate 5, a screw-in mechanism 7 is provided on the outer surface of the driving assembly 3, a driving screw 8 is provided at the output end of the driving assembly 3, an oil filter device 9 is threadedly connected to the outer surface of the driving screw 8, a first guide pipe 10 and a second guide pipe 11 are respectively arranged on the outer surface of the separation tank 1, a second separation tank 12 is arranged at one end of the first guide pipe 10, and an isolation mechanism 13 is arranged inside the second separation tank 12.

[0031] When it is necessary to separate the oil-water mixture produced in the preparation process of hexamethyldisiloxane, when the oil and water are introduced into the separation tank 1 through the inlet pipe 4, the top driving component 3 is started so that its output end drives the screw-in mechanism 7 to rotate inside the accommodating chamber 2. When the oil and water enter the accommodating chamber 2, they flow into the separation tank 1 through the guide port 6 on the top of the guide plate 5. At this time, the internal liquid level gradually rises. At the same time, the driving screw 8 at the bottom is driven by the driving component 3 to drive the oil filter device 9 to move inside the separation tank 1. Since the oil filter device 9 is lipophilic, the oil is adsorbed on its surface when it rises, and the water is filtered below. After the inlet pipe 4 stops guiding, the oil level gradually rises to the top of the guide plate 5, and the screw-in mechanism 7 continues to rotate to generate centrifugal force to make the oil enter the first guide pipe 10 and be discharged into the second separation tank 12. The water separated at the bottom is introduced into the second separation tank 12 by the second guide pipe 11 and is blocked in the lower layer by the isolation mechanism 13.

[0032] The utility model provides a screw-in mechanism 7 at the output end of the driving component 3 so that it can continuously operate above the guide plate 5, and cooperates with the driving screw 8 to drive the oil filter device 9 to perform longitudinal displacement below it, so that when the oil and water enter the interior of the accommodating chamber 2, the oil located in the upper layer is driven to flow upward by the oil filter device 9 through the displacement from bottom to top, so that the liquid level gradually rises to the top of the guide plate 5, and then cooperates with the continuously operating screw-in mechanism 7 to quickly rotate and guide it to the interior of the first guide pipe 10, and cooperates with the second guide pipe 11 to guide the water into the lower layer inside the second separation tank 12, and at the same time, the isolation mechanism 13 is used to store it in layers for subsequent fractionation, thereby improving the oil-water separation efficiency and increasing the separation effect of a small amount of water in the oil, and reducing the time consumption in the oil-water separation process.

[0033] In one embodiment, for the above-mentioned separation tank 1, a top cover 14 is provided on the top of the separation tank 1, the driving assembly 3 includes a driving motor 301, a driving shaft 302 is provided at the output end of the driving motor 301, the screw-in mechanism 7 is fixedly connected to the outside of the driving shaft 302, and the screw-in mechanism 7 is located above the guide plate 5.

[0034] By starting the driving motor 301 to drive the driving shaft 302 to rotate, the bottom of the motor 301 penetrates the bottom of the guide plate 5 to drive the driving screw 8 to rotate, and at the same time, the driving shaft 302 drives the screw-in mechanism 7 to rotate above the guide plate 5 to guide the flow.

[0035] By fixing the driving motor 301 on the top of the top cover 14, the driving shaft 302 extends to the interior of the separation tank 1, so that the driving shaft 302 can cooperate with the screw-in mechanism 7 and the oil filter device 9 at the bottom to continuously provide driving force, so that the oil in the oil and water can be effectively and quickly separated.

[0036] In one embodiment, for the above-mentioned screw-in mechanism 7, the screw-in mechanism 7 includes a sleeve 701, and a swirl plate 702 is fixedly installed on the outer surface of the sleeve 701. The swirl plates 702 are distributed outside the sleeve 701 in a cross shape.

[0037] When the driving shaft 302 is driven to rotate, the sleeve 701 is driven to rotate to drive the cross-distributed swirl plates 702 to move in a circle above the guide plate 5, so that the swirl plates 702 continue to rotate to push the oil to generate centrifugal force and gradually flow into the first guide pipe 10, thereby improving the oil separation and discharge efficiency.

[0038] In one embodiment, for the above-mentioned oil filter device 9, the oil filter device 9 includes a threaded sleeve 901, the outer surface of which is fixedly connected to an oil filter plate 902, the outer surface of which is symmetrically provided with a guide sliding block 903, and the guide sliding block 903 is slidably connected to the inner wall of the separation tank 1.

[0039] When the driving screw 8 is driven to rotate, the threaded sleeve 901 is driven to move from bottom to top on its outside, and at the same time, the guide sliding blocks 903 on both sides are driven to slide on the inner wall of the separation tank 1. When the threaded sleeve 901 moves, it drives the oil filter plate 902 to move upward and pushes the oil upward, and the lower layer of water is gradually filtered by the oil filter plate 902 and flows downward.

[0040] By fixing the oil filter plate 902 on the outside of the threaded sleeve 901 and cooperating with the drive shaft 302 to drive the drive screw 8 to rotate, the oil filter plate 902 is provided with a displacement driving force, so that the lipophilic oil filter plate 902 can block the oil and adsorb it on the upper surface of the oil filter plate 902 and gradually push it to the top of the guide plate 5, and cooperate with the cyclone plate 702 to gradually discharge the upper layer of oil, so that the oil-water separation efficiency is higher.

[0041] In one embodiment, for the above-mentioned driving screw 8, the outer surface of the driving screw 8 is fixedly connected to a connecting rod 15, and one end of the connecting rod 15 is fixedly connected to a closing plate 16, and the closing plate 16 is arc-shaped, and the outer surface of the closing plate 16 is in contact with the inner wall of the separation tank 1.

[0042] When the driving screw 8 rotates, the connecting rod 15 at the bottom thereof is driven to rotate and then drives the closing plate 16 to rotate in close contact with the inner wall of the separation tank 1. When the closing plate 16 is rotated to a point away from the outlet of the second guide tube 11, its guide port is opened, and the lower layer of water enters the interior of the second guide tube 11. When the closing plate 16 rotates, its outlet is blocked and closed at the guide port, and the lower layer of water no longer continues to flow, thereby slowing down the guide rate of the lower layer of water inside the separation tank 1, preventing the water from flowing too fast and carrying away part of the oil and reducing the oil-water separation effect.

[0043] In one embodiment, for the second separation tank 12 , a heating bucket 17 is disposed at the bottom of the second separation tank 12 , a top cover 18 is disposed at the top of the second separation tank 12 , and a vent hole 19 is opened at the top of the top cover 18 .

[0044] By setting the heating bucket 17 at the bottom of the second separation tank 12, when the lower layer of water enters the interior of the second separation tank 12 through the second guide pipe 11, it is blocked on the west side of the isolation mechanism 13. After being heated by the heating bucket 17, the water is evaporated, and its steam flows upward to distill the oil on the top of the isolation mechanism 13.

[0045] In one embodiment, for the above-mentioned isolation mechanism 13, the isolation mechanism 13 includes an isolation plate 1301, and the top of the isolation plate 1301 is fixedly connected with an isolation tube 1302.

[0046] By setting the isolation plate 1301 at the upper position inside the second separation tank 12, when the oil enters, it is blocked at the top by the isolation plate 1301, and the bottom heating bucket 17 heats up the water inside to generate steam and flow to the inside of the isolation tube 1302, while distilling the oil, so that the small amount of water contained in the temporal part is separated again, so that the oil is distilled again through the separated lower layer water, so that the oil-water separation is better.

[0047] In one embodiment, for the second separation tank 12 , an oil drain pipe 20 and a bottom outlet pipe 21 are respectively disposed on the outer surface of the second separation tank 12 .

[0048] The oil discharge pipe 20 is located at the upper position of the second separation tank 12, so as to provide a discharge channel for the oil after distillation, and the bottom outlet pipe 21 provides a discharge channel for the lower layer residual water after distillation.

[0049] Through the above technical scheme, 1. By respectively arranging a screw-in mechanism 7 at the output end of the driving assembly 3 so that it can continuously operate above the guide plate 5, and cooperate with the driving screw 8 to drive the oil filter device 9 to perform longitudinal displacement below it, and then when the oil and water enter the interior of the accommodating chamber 2, the oil located in the upper layer is driven to flow upward by the oil filter device 9 from bottom to top, so that its liquid level gradually rises to the top of the guide plate 5, and then cooperates with the continuously operating screw-in mechanism 7 to quickly rotate and guide it to the interior of the first guide pipe 10, and cooperates with the second guide pipe 11 to guide the water into the lower layer of the second separation tank 12, and at the same time, the isolation mechanism 13 is used to After being stored in layers, it is convenient for subsequent distillation, which improves the oil-water separation efficiency while increasing the separation effect of a small amount of water in the oil and reduces the time consumption in the oil-water separation process; 2. By setting the isolation plate 1301 at the upper layer inside the second separation tank 12, when the oil enters, it is blocked at the top by the isolation plate 1301, and the bottom heating bucket 17 heats and raises the temperature so that the water inside generates steam and flows into the isolation tube 1302, and at the same time distills the oil, so that the small amount of water contained in its temporal part is separated again, so that the oil is distilled again through the separated lower layer of water, so that the oil-water separation is better.
