[0002] Benzene is the simplest aromatic hydrocarbon. It is insoluble in water but soluble in organic solvents. It can also be used as an organic solvent. In actual production and storage, benzene may absorb moisture from the air, so the benzene you buy usually contains some moisture. In addition, benzene may also come into contact with water in certain chemical experiments or industrial processes. For example, when used as a solvent, it may mix with water-containing substances, resulting in water in benzene.
[0003] In the prior art, benzene inevitably carries water during storage, which affects the purity of benzene. Therefore, the water in benzene needs to be removed before it is used. However, both water and benzene are colorless liquids, and the separation layer of benzene and water cannot be visually seen. Therefore, it is difficult to remove the water in benzene by stratified separation, which may result in incomplete water separation or benzene being discharged and wasted. Utility Model Content

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0024] Example:
[0025] Reference Figure 1 - Figure 5 The utility model discloses an automatic benzene-water separation device, comprising a liquid separator 1, a liquid inlet pipe 2 for inputting a solution is fixedly connected to the top of the outer wall of the liquid separator 1, a drain pipe 3 is arranged at the bottom of the liquid separator 1, an outer wall of the drain pipe 3 is connected to a solenoid valve 4, a laser generator 5 is arranged on the outer side of the liquid separator 1, both sides of the laser generator 5 are rotatably connected to support plates 6, a side of the support plate 6 away from the laser generator 5 is fixedly connected to the outer wall of the liquid separator 1, a light sensor 7 for receiving a laser signal is embedded in the inner bottom wall of the liquid separator 1, and a centrifugal component 8 for accelerating stratification is arranged in the liquid separator 1.
[0026] In this embodiment, because benzene will inevitably come into contact with air during the production and storage process, causing the benzene solution to absorb moisture in the air, the benzene solution needs to be separated from water before use to increase the purity of benzene and avoid the presence of water affecting the addition of benzene.
[0027] Because the density of benzene and water is different, the water will automatically separate from the benzene during the static process of the benzene-water mixed solution and gather at the bottom of the liquid separator 1. This static time is usually long, which will affect the efficiency of benzene-water separation. Therefore, it is necessary to observe Figure 2 It can be found that a centrifugal component 8 is provided in the separator 1, and the centrifugal component 8 is used to drive the benzene-water mixed solution in the separator 1 to rotate at a high speed, so that the water with higher density is thrown on the outer circle of the mixed solution, and the benzene is located in the inner circle of the mixed solution. After the centrifugation is completed, the water located in the outer circle will directly contact the inner wall of the separator 1 and will directly converge downward along the inner wall of the separator 1, which can effectively accelerate the stratification of the crushed mixed solution, thereby improving the efficiency of benzene-water separation.
[0028] Since benzene and water are both colorless liquids, although benzene and water will separate due to different densities, it is impossible to intuitively determine where the separation interface between benzene and water is, so the mixed solution of benzene and water cannot be separated by the separation method. Figure 1 It can be found that a laser generator 5 is arranged on the outside of the liquid separator 1. The laser emitted by the laser generator 5 is deflected when passing through materials of different densities to determine the layering of benzene and water. This can be used to control the discharge of water after the benzene-water mixed solution is stratified, avoid the waste of benzene due to discharge, and effectively improve the water separation efficiency.
[0029] However, due to the interference of the outer shell of the liquid distributor 1, when using the deflection of light to determine the stratification level, the observation field of view needs to be kept horizontal with the stratification level to obtain the best observation field of view, which will lead to the need for continuous observation during the drainage process, increasing the physical consumption of the operator, so the observation Figure 1 It can be found that a light sensor 7 is embedded in the inner bottom wall of the liquid dispenser 1, and a solenoid valve 4 is provided on the drain pipe 3. The light sensor 7 can be used to receive the optical signal of the laser generator 5 to control the opening and closing of the solenoid valve 4, so that the automatic benzene-water separation device can automatically control the drainage, which can effectively reduce the difficulty of using the automatic benzene-water separation device and improve the efficiency of benzene-water separation.
[0030] observe Figure 3 It can be found that when using, the purified benzene is first injected (as shown in A1 in the figure), and then Figure 3 As shown in the figure, the irradiation angle of the laser generator 5 is adjusted so that the laser falls on the light sensor 7 after refraction, and the calibration of the laser generator 5 and the light sensor 7 is completed. Then the pure benzene solution is extracted and the benzene-water mixed solution to be purified is poured in. At this time, the mixed solution is as follows Figure 4 As shown in A2 in FIG. 1 , the density of the mixed benzene aqueous solution changes, causing the refraction angle of the light to change, thereby changing the landing point of the laser after refraction, so that the light sensor 7 cannot receive the laser signal. Then, the centrifugal assembly 8 is started to centrifuge the benzene-water mixed solution, so that the benzene and water are mixed as shown in FIG. Figure 5 The separation is shown as A3 and A4 in FIG. Figure 6 As shown in A5 and A6 in the figure, water flows down along the inner wall of the liquid separator 1 to the bottom of the liquid separator 1, while the benzene solution with a smaller mass will be gathered above the water. At this time, the solenoid valve 4 is opened and the water is discharged through the drain pipe 3.
[0031] As the water is discharged, the separation layer of benzene and water will gradually move downward, thereby causing the refraction point of the laser to move downward until the water is completely discharged and only high-purity benzene solution exists in the liquid separator 1. At this time, the refraction point of the laser will return to the original calibrated position, causing the light sensor 7 to close the solenoid valve 4 after receiving the signal to prevent the benzene solution from being discharged, making the use of the benzene-water automatic separation device simpler and easier to operate, and effectively improving the efficiency of benzene-water separation.
[0032] Finally, after the benzene-water separation is completed, the remaining benzene solution is discharged into the benzene solution storage tank through the drain pipe, and then the new benzene-water mixed solution is discharged into the separator 1. The above operation is repeated to separate the benzene and water, and the water in the benzene solution can be separated efficiently.
[0033] In a further preferred embodiment of the present invention, Figure 2 As shown, the bottom diameter of the liquid distributor 1 gradually decreases from top to bottom to form a closing portion 9 , and the bottom diameter of the closing portion 9 is larger than the diameter of the drain pipe 3 .
[0034] In this embodiment, water will gradually enter the drain pipe 3 and be discharged under the pressure of gravity and the benzene solution, and form a very thin water film on the inner bottom wall of the dispenser 1 when it is about to be discharged. This water film has little interference with the refraction deviation angle of the laser, so that when the light sensor 7 receives the light signal, less water will remain in the dispenser 1, which will cause incomplete discharge of the water.
[0035] So observe Figure 2 It can be found that gradually reducing the bottom diameter of the separator 1 from top to bottom to form a closing portion 9 can be used to reduce the area of the bottom of the separator 1, thereby reducing the total amount of water film and minimizing water residue, thereby improving the purification effect of the benzene solution.
[0036] In a further preferred embodiment of the present invention, Figure 3 As shown, the light sensor 7 is arranged on a side of the closing portion 9 close to the drain pipe 3 , and the top of the light sensor 7 is flush with the inner bottom wall of the closing portion 9 .
[0037] In this embodiment, by placing the light sensor 7 close to the drain pipe 3, the bottom area of the liquid separator 1 can be made as small as possible to improve the benzene-water separation effect. By making the top of the light sensor 7 flush with the inner bottom wall of the closing portion 9, the inner bottom wall of the liquid separator 1 can be kept flat, which is used to prevent the light sensor 7 from extending out of the bottom of the liquid separator 1, resulting in some undischarged water remaining at the bottom of the liquid separator 1 when the light sensor 7 receives the light signal, which can effectively avoid water residue and improve the purification effect of the benzene solution.
[0038] In a further preferred embodiment of the present invention, Figure 2As shown, both sides of the laser generator 5 are connected with dampers through a rotating shaft, and the side of the damper away from the laser generator 5 is rotatably connected to the support plate 6.
[0039] In this embodiment, because the laser generator 5 needs to rotate to adjust the refraction point of the light, the laser generator 5 cannot be fixed on the outer wall of the dispenser 1. Because the laser generator 5 itself has weight, the laser generator 5 will gradually deflect around the rotation axis under the action of gravity after the angle adjustment is completed, affecting the final landing point of the laser, thereby affecting the drainage effect of benzene-water separation. Therefore, a damper is provided on the outer wall of the laser generator 5, so that when the laser generator 5 is deflected by gravity, it will also be supported by the damping force of the damper, which can avoid the laser generator 5 from deflecting, thereby ensuring the purification accuracy of the benzene solution of the benzene-water automatic separation device.
[0040] In a further preferred embodiment of the present invention, Figure 2 and Figure 5 As shown, the centrifugal assembly 8 includes a motor 81, a connecting rod 82 and a stirring blade 83. The motor 81 is fixedly connected to the top of the dispenser 1. The output shaft of the motor 81 extends into the interior of the dispenser 1 and is fixedly connected to the connecting rod 82. The outer wall of the connecting rod 82 is provided with a plurality of stirring blades 83 in a circular array.
[0041] In this embodiment, because water needs to squeeze out the benzene solution at the bottom during its downward movement under gravity, the water will not only be affected by the electrostatic force of the benzene solution on the side, but also by the support force of the benzene solution at the bottom, which makes the separation efficiency of benzene and water low. Figure 2 It can be found that a motor 81 is provided at the top of the liquid dispenser 1, and the motor 81 drives the connecting rod 82 to rotate at a high speed, so that the stirring blade 83 on the outer wall of the connecting rod 82 stirs the benzene-water mixed solution, so that the benzene-water mixed solution is Figure 5 The separation shown in A3 and A4 in the figure makes the water with higher density be centrifuged to the outside of the solution, so that the water will not be supported by the benzene solution during its downward movement, which can effectively improve the efficiency of benzene-water stratification and thus improve the efficiency of benzene-water separation.
[0042] In a further preferred embodiment of the present invention, Figure 2 As shown, the bottom of the connecting rod 82 is rotatably connected to a collar 10 , and the outer wall of the collar 10 is fixedly connected to the inner wall of the dispenser 1 via a support rod 11 .
[0043] In this embodiment, by providing a collar 10 at the bottom of the connecting rod 82 and fixing the collar 10 to the liquid dispenser 1 by using a support rod 11, the connecting rod 82 can remain stable when rotating at high speed, thereby reducing the wear generated during the operation of the centrifugal assembly 8, and effectively extending the service life of the automatic benzene-water separation device, thereby reducing the use cost of the automatic benzene-water separation device.
[0044] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
