Description

Technical Field

[0001] The utility model relates to the technical field of an ethanol distillation device, and specifically relates to an ethanol distillation device. Background Art

[0002] Ethanol is a simple organic compound with the chemical formula C2H5OH. It is a colorless, transparent, volatile liquid with a special smell at room temperature. Ethanol is widely used in many fields, including industry, medicine, cosmetics, food and beverages, etc., and the ethanol distillation unit is a device used to separate ethanol and water in a mixture. The principle is to use the difference in boiling points of ethanol and water at different temperatures to separate them. Since the boiling point of ethanol is lower than that of water, by heating the mixture, the ethanol will first be vaporized and rise through the distillation tower, and then cooled into a liquid in the condenser, and finally pure ethanol will be separated.

[0003] The ethanol distillation device in the prior art has the following technical problems during use: the existing working method is to heat and stir the ethanol solution to be processed so that the ethanol solution can quickly heat up, and then after reaching the boiling point, the vaporized ethanol moves to the condensation component with water vapor, and then the condensed ethanol solution is collected, that is, the distillation operation is performed by the method of absorbing the vaporized ethanol while distilling. However, this processing method is only suitable for small-batch diversion operations. In large-scale operations, it is necessary to manually continuously add new solution to be distilled to the distillation device to ensure the distillation efficiency of the ethanol solution. The newly added ethanol solution will mix with the heated ethanol solution to lower the overall temperature. The heating chamber needs to be heated repeatedly, and the heating time needs to be waited, which reduces the heating efficiency of the ethanol solution and increases the diversion time of ethanol, thereby reducing the diversion efficiency of the ethanol solution, while increasing energy loss and reducing practicality.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0023] like Figure 1 to Figure 5As shown, this embodiment proposes an ethanol distillation device, including a distillation shell 32, a water storage tank 324 for storing the ethanol solution to be distilled and a water outlet tank 325 for discharging the ethanol solution containing most of the water content, which are respectively arranged on the upper and lower sides of the distillation shell 32, and a plurality of diversion chambers 321 for distilling and diverting the ethanol solution are arranged between the water storage tank 324 and the water outlet tank 325, and the upper and lower ends of each diversion chamber 321 are respectively connected to the water storage tank 324 and the water outlet tank 325, a feed pipe 31 is fixedly connected to the upper end of the distillation shell 32, a water outlet pipe 33 is fixedly connected between the lower end of the water outlet tank 325 and the inner wall of the distillation shell 32, and a pressure dividing component 2 for increasing the diversion efficiency of the ethanol solution is connected between the feed pipe 31 and the water outlet pipe 33. The pressure divider component 2 can automatically replenish the distilled ethanol solution in the water tank 324 and discharge the ethanol solution after distillation. No manual operation is required, which reduces the labor intensity of the operator. It can be suitable for large-scale processing operations and increases practicality. At the same time, it increases the diversion effect of the ethanol solution and improves the diversion efficiency, and accelerates the condensation efficiency of vaporized ethanol, reduces the condensation time loss of vaporized ethanol, and further improves the diversion efficiency of the ethanol solution. The driving component that drives the pressure divider component 2 and performs stirring operations in each diversion chamber 321 is connected to one side of the pressure divider component 2. The driving component and the heating strip 34 that heats each diversion chamber 321 are detachably fixedly connected in the distillation shell 32.

[0024] like Figure 2 to Figure 4As shown, the pressure dividing assembly 2 includes an active column 21, which is rotatably connected to the distillation shell 32, and a first blocking plate 22 and a second blocking plate 25 are fixedly connected to the upper and lower ends of the active column 21 respectively. The first blocking plate 22 abuts against the bottom wall of the water storage tank 324, and the second blocking plate 25 abuts against the upper wall of the water outlet tank 325. The first blocking plate 22 and the second blocking plate 25 are used to seal each diversion chamber 321 into a separately closed cavity, laying the foundation for subsequent diversion operations. The outlet pipe 24 is fixedly connected to the first blocking plate 22. When the ethanol gas is discharged through the outlet pipe 24, it can be separated from the ethanol solution with distillation above the first blocking plate 22 so that they do not interfere with each other. At the same time, the ethanol solution to be distilled outside the outlet pipe 24 can The outlet pipe 24 has a cooling effect so that the high-temperature vaporized ethanol passing through the outlet pipe 24 can be quickly condensed, that is, the condensation efficiency of the vaporized ethanol is increased. At the same time, the diameter of the outlet pipe 24 is smaller than the diameter of the diversion cavity 321. According to Bernoulli's principle, when the fluid flows through a smaller cross-sectional area, its velocity will increase and the pressure will decrease. When the air flow flows from a large aperture to a small aperture, the cross-sectional area becomes smaller, the air flow velocity increases, and the pressure decreases. According to the ideal gas law, the pressure and temperature of the gas are proportional. Therefore, a decrease in pressure will lead to a decrease in temperature, thereby further increasing the condensation efficiency of the vaporized ethanol. The cover plate 23 is fixedly connected to one end of the outlet pipe 24 away from the first blocking plate 22, and the cover plate 23 is rotatably connected to the upper inner wall of the water storage tank 324.

[0025] like Figure 2 to Figure 4 As shown, the water inlet hole 322 and the drainage hole 323 are respectively concentrically opened on the upper and lower sides of the diversion chamber 321, the first water down hole 221 is opened on the first blocking plate 22, the first water down hole 221 and the air outlet pipe 24 are both concentric with the water inlet hole 322, the second water down hole 251 is opened on the second blocking plate 25, and the second water down hole 251 is concentric with the drainage hole 323, so that the first water down hole 221, the air outlet pipe 24 and the second water down hole 251 can work in conjunction with the same diversion chamber 321 in sequence.

[0026] like Figure 2 to Figure 5 As shown, the first water hole 221, the air outlet pipe 24 and the second water hole 251 are not concentric, so that the plurality of diverter chambers 321 can work independently. When the water storage tank 324 is filled with ethanol solution, when the first water hole 221 is connected with one of the diverter chambers 321, the ethanol solution will flow into the diverter chamber 321 through the water inlet hole 322 according to its own weight. The aperture of the water inlet hole 322 can limit the flow rate entering the diverter chamber, and the rotation speed of the transmission gear 16 can limit the flow rate entering the diverter chamber at a single time. At this time, one diverter chamber 321 starts to work and performs diverting operation on the ethanol solution therein;

[0027] Further explanation, when the first water hole 221, the air outlet pipe 24 and the second water hole 251 are not connected to any of the diverter chambers 321, the diverter chamber 321 is an independent closed chamber at this time, and the diverter chamber 321 is heated, and the highest temperature of the heating is between the boiling point of water and the boiling point of ethanol. The vaporization of ethanol will pressurize the closed chamber, so that the pressure of the closed chamber is greater than the external pressure. At the same time, the closed chamber ensures the heating effect, so that the heating efficiency of ethanol is faster, and the heating efficiency is improved. When the first water hole 221 is heated, the air outlet pipe 24 and the second water hole 251 are connected to any of the diverter chambers 321, and the diverter chamber 321 is heated, and the highest temperature of the heating is between the boiling point of water and the boiling point of ethanol. The vaporization of ethanol will pressurize the closed chamber, so that the pressure of the closed chamber is greater than the external pressure. At the same time, the closed chamber ensures the heating effect, so that the heating efficiency of ethanol is faster, and the heating efficiency is improved. When 221 is connected to the next shunt chamber 321, similarly, it indicates that the outlet pipe 24 is connected to the previous shunt chamber 321, and high pressure is instantly released from the outlet pipe 24. This high pressure increases the flow rate of the ethanol gas through the outlet pipe 24, thereby reducing the temperature and increasing the condensation effect. The outlet pipe 24 can also condense the ethanol gas in the outlet pipe 24 through the external ethanol liquid to be distilled, reducing the loss of the external condensation equipment. With the rotation of the transmission gear 16, the shunt chamber 321 returns to the closed state;

[0028] Because the earliest diverter chamber 321 has diverted most of the vaporized ethanol, the overall mass of the ethanol solution in this diverter chamber 321 is reduced, but it is still in a heated state, so that part of the vaporized ethanol and water continue to be separated in the remaining ethanol solution, the vaporized ethanol solution is at the top, and the water is at the bottom. When the second water hole 251 is connected to the earliest diverter chamber 321, the water, which is heavier than the vaporized ethanol, will be discharged through the second water hole 251 first, ensuring that when this diverter chamber 321 is reclosed, there will still be a small amount of water remaining in this diverter chamber 321. In order to block that part of the vaporized ethanol and prevent the distillation shell 32 from exploding due to waterless heating, thereby increasing the service life of the distillation shell 32, the pressure in the earliest cavity at this time has been greatly reduced, waiting for the next communication with the first water hole 221, and then the new ethanol solution to be distilled can be added through the first water hole 221. The newly added room temperature ethanol solution will not affect other heated ethanol solutions, thereby increasing the output efficiency of the ethanol solution.

[0029] like Figure 2 to Figure 5As shown, the driving assembly includes a sealing plate 18, which is fixedly connected to the lower side of the distillation shell 32. The sealing plate 18 is used to protect the components between the sealing plate 18 and the distillation shell 32. The first linkage column 131 and the two second linkage columns 132 are rotatably connected between the sealing plate 18 and the distillation shell 32. Each stirring blade 12 is fixedly connected to the first linkage column 131 and the two second linkage columns 132 at one end away from the sealing plate 18. The driving motor 17 is fixedly connected to the lower end of the sealing plate 18, and the driving shaft of the driving motor 17 is fixedly connected to the first linkage column 131. The stirring blade 12 stirs the heated ethanol solution in each diversion chamber 321 to increase the heat conduction inside the ethanol solution, so that the ethanol solution can reach the boiling point of ethanol faster, thereby shortening the diversion time and improving the diversion efficiency of the ethanol solution.

[0030] like Figure 2 to Figure 5 As shown, each synchronous wheel 14 is fixedly connected to the first linkage column 131 and the two second linkage columns 132 at one end away from the stirring blade 12, and each synchronous wheel 14 is meshed with a synchronous belt 15. The rotation of the first linkage column 131 is synchronized to the second linkage column 132 through the synchronous belt 15, so that the ethanol solution can be stirred in each diversion chamber 321, the heat conduction effect of the ethanol solution under high temperature is increased, and the ethanol with a lower melting point can be diverted out faster, that is, the diversion effect of the ethanol solution is increased.

[0031] like Figure 3 and Figure 5 As shown, the first linkage column 131 is fixedly connected to the intermittent gear 11, one side of the intermittent gear 11 is meshed with the transmission gear 16, and the transmission gear 16 is fixedly connected to the lower end of the active column 21. The intermittent gear 11 can make the transmission gear 16 rotate intermittently, that is, the rotation speed of the transmission gear 16 can be controlled by the rotation speed of the intermittent gear 11, so that the pressure dividing component 2 can reasonably cooperate with each diversion chamber 321.

[0032] The working principle of this embodiment is:

[0033] After ensuring that each of the diverter cavities 321 is dry, the water storage tank 324 is filled with ethanol solution. When the first water discharge hole 221 is connected to one of the diverter cavities 321, the ethanol solution will flow into the diverter cavities 321 through the water inlet hole 322 according to its own weight. The aperture of the water inlet hole 322 can limit the flow rate entering the diverter cavity. The rotation speed of the transmission gear 16 can limit the flow rate entering the diverter cavity at a single time. At this time, one of the diverter cavities 321 starts to work and performs diversion operation on the ethanol solution therein.

[0034] When the first water hole 221, the air outlet pipe 24 and the second water hole 251 are not connected to any of the diverter chambers 321, the diverter chamber 321 is an independent closed chamber. The diverter chamber 321 is heated. The highest temperature of the heating is between the boiling point of water and the boiling point of ethanol. The vaporization of ethanol will pressurize the closed chamber, making the pressure of the closed chamber greater than the external pressure. At the same time, the closed chamber ensures the heating effect, making the heating efficiency of ethanol faster and improving the heating efficiency. When the first water hole 221 is heated, the air outlet pipe 24 and the second water hole 251 are connected to any of the diverter chambers 321. When the outlet pipe 24 is connected to the next shunt chamber 321, similarly, it indicates that the outlet pipe 24 is connected to the previous shunt chamber 321, and high pressure is released from the outlet pipe 24 instantly. This high pressure increases the flow rate of the ethanol gas through the outlet pipe 24, thereby reducing the temperature and increasing the condensation effect. The outlet pipe 24 can also condense the ethanol gas in the outlet pipe 24 through the external ethanol liquid to be distilled, thereby reducing the loss of the external condensation equipment. As the transmission gear 16 rotates, the shunt chamber 321 returns to the closed state;

[0035] Because the earliest diverter chamber 321 has diverted most of the vaporized ethanol, the overall mass of the ethanol solution in this diverter chamber 321 is reduced, but it is still in a heated state, so that the remaining ethanol solution continues to separate part of the vaporized ethanol from the water, and the vaporized ethanol solution is at the top and the water is at the bottom. When the second water hole 251 is connected to the earliest diverter chamber 321, the water, which is heavier than the vaporized ethanol, will be discharged through the second water hole 251 first, ensuring that when this diverter chamber 321 is reclosed, there will still be a small amount of water remaining in this diverter chamber 321. In order to block that part of the vaporized ethanol and prevent the distillation shell 32 from exploding due to waterless heating, thereby increasing the service life of the distillation shell 32, the pressure in the earliest cavity at this time has been greatly reduced, waiting for the next communication with the first water hole 221, so that new ethanol solution to be distilled can be added through the first water hole 221.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
