[0030] In one embodiment, Figure 1-Figure 7 As shown, a mixed aromatic solvent distillation separation device comprises a reaction tank 1, a connecting mechanism 2 and a discharging mechanism 3, wherein the connecting mechanism 2 is equidistantly distributed in an annular manner on the outside of the reaction tank 1, one end of the connecting mechanism 2 is connected to the discharging mechanism 3, a top cover 6 is fixedly installed on the top of the reaction tank 1, a stirring mechanism 7, a feeding pipe 8 and a heating mechanism 9 are respectively arranged on the top of the top cover 6, a second water trough 13 is opened on the inner wall of the reaction tank 1, a second water inlet pipe 11 and a second water outlet pipe 12 are respectively arranged on the outside of the reaction tank 1, and the second water outlet pipe 12 is located above the second water inlet pipe 11, and a discharging pipe 10 is arranged at the bottom of the reaction tank 1.

[0031] In this embodiment, the connection mechanism 2 and the fixing mechanism 14 are provided to facilitate the installation or disassembly of the discharge mechanism 3 and the reaction tank 1. When the discharge mechanism 3 is damaged or needs to be cleaned, the discharge mechanism 3 is disassembled and replaced with a new one to avoid the disassembly and installation time of the discharge mechanism 3 being too long, which leads to a decrease in the separation work efficiency. Hot water is injected into the second water tank 13 through the second water inlet pipe 11. After the hot water fills the second water tank 13, it is discharged through the second water outlet pipe 12. The discharged water is heated again and introduced into the second water tank 13 through the second water inlet pipe 11 to complete the circulation of hot water. The mixed aromatic solvent in the reaction tank 1 can be quickly heated by the hot water. At the same time, the water heating improves the uniformity of heating. The mixed aromatic solvent can be heated by electric heating through the setting of the heating mechanism 9. The mixed aromatic solvent can be stirred by the setting of the stirring mechanism 7 to ensure that the temperature of the mixed aromatic solvent is uniform and the separation efficiency is improved.

[0032] In one embodiment, Figure 3As shown, the connecting mechanism 2 includes a first connecting block 201, the first connecting block 201 is fixedly installed on the outside of the reaction tank 1 in an equidistant ring, a second connecting tube 202 is fixedly installed inside the first connecting block 201, a third connecting tube 203 is fixedly installed inside the second connecting tube 202, a mounting groove 204 is provided inside the third connecting tube 203, a moving sleeve 205 is slidably installed inside the mounting groove 204, a first spring 206 is placed inside the mounting groove 204, and one end of the first spring 206 is fitted with one side of the moving sleeve 205, a sliding groove 207 is symmetrically provided on the outside of the second connecting tube 202, a connecting rod 208 is symmetrically fixedly installed on the outside of the moving sleeve 205, and the connecting rod 208 passes through the second connecting tube 202 through the sliding groove 207, a rack 209 is fixedly installed on one end of the connecting rod 208, and a fixed block 210 is symmetrically fixedly installed on the outside of the third connecting tube 203, and a first gear 211 and a second gear 211 are rotatably installed on one side of the plurality of fixed blocks 210. The first gear 211 and the second gear 212 are meshed with each other, the first gear 211 and the rack 209 are meshed with each other, and a cover plate 213 is fixedly installed on the outside of the second gear 212. When the first connecting block 201 is not connected to the air inlet pipe 301, since the first spring 206 is in a compressed state, the movable sleeve 205 is located at the outermost part, and the cover plate 213 blocks one end of the third connecting pipe 203, and a sealing gasket is provided between the cover plate 213 and the third connecting pipe 203 to ensure sealing. The air pipe 301 is inserted into the movable sleeve 205, so that the movable sleeve 205 slides toward the inside of the installation groove 204, the first spring 206 is compressed, and the rack 209 moves together due to the setting of the connecting rod 208, the rack 209 drives the first gear 211 to rotate, the first gear 211 drives the second gear 212 to rotate, and the second gear 212 drives the cover plate 213 to flip, so that one end of the third connecting pipe 203 is opened. At this time, the substance heated and evaporated inside the reaction tank 1 is introduced into the interior of the air pipe 301 through the third connecting pipe 203.

[0033] In one embodiment, Figure 3 As shown, a fixing mechanism 14 is symmetrically provided at one end of the third connecting pipe 203, and the air inlet pipe 301 and the third connecting pipe 203 can be effectively fixed by the fixing mechanism 14. When the air inlet pipe 301 needs to be removed, it only needs to be rotated, which is efficient and quick.

[0034] In one embodiment, Figure 4As shown, the fixing mechanism 14 includes a mounting block 1401, and the mounting block 1401 is symmetrically fixedly mounted on one end of the third connecting pipe 203. A sliding rod 1402 is slidably mounted on one side of the outer side of the mounting block 1401, and a second latching tooth 1403 is fixedly mounted on one end of the sliding rod 1402. A second spring 1404 is sleeved on the outer side of the sliding rod 1402, and the second spring 1404 is located between the mounting block 1401 and the second latching tooth 1403. During the insertion of the air inlet pipe 301, the first latching tooth 302 and the second latching tooth 1403 are fixedly mounted. The second latch tooth 1403 contacts the first latch tooth 302, and since the two are adapted to each other, the second latch tooth 1403 moves during the insertion of the air inlet pipe 301, and the second spring 1404 is always in a compressed state, causing the second latch tooth 1403 to always fit with the first latch tooth 302, making it impossible for the air inlet pipe 301 to be pulled out. When the air inlet pipe 301 needs to be removed, the air inlet pipe 301 is rotated to change the positions of the first latch tooth 302 and the second latch tooth 1403, causing the engagement between the two to be released, and the air inlet pipe 301 can be removed at this time.

[0035] In one embodiment, Figure 4 and Figure 5 As shown, the discharging mechanism 3 includes an air inlet pipe 301, and the air inlet pipe 301 is installed inside the movable sleeve 205. The outside of the air inlet pipe 301 is symmetrically fixed with a first latch tooth 302, and the first latch tooth 302 is adapted to the second latch tooth 1403, and the second latch tooth 1403 is adapted to the first latch tooth 302, so that the air inlet pipe 301 can only move inward and cannot be pulled out.

[0036] In one embodiment, Figure 6 As shown, a fixed cover 303 is fixedly installed at one end of the air inlet pipe 301, an air outlet pipe 304 is fixedly installed on the outside of the fixed cover 303, a groove 305 and a thread groove 306 are respectively opened at the bottom of the fixed cover 303, the groove 305 is communicated with the air inlet pipe 301, the air outlet pipe 304 is communicated with the thread groove 306, the inner thread of the thread groove 306 is connected with a threaded cylinder 307, a filter element 308 is fixedly installed at the bottom of the threaded cylinder 307, and the bottom of the fixed cover 303 is fixedly installed A separation tank 309 is provided, and the separation tank 309 is located outside the filter element 308. A discharge pipe 313 is fixedly installed at the bottom of the separation tank 309. The heated and volatilized substance enters the groove 305 through the air inlet pipe 301, and then enters the interior of the separation tank 309 through the groove 305. By cooling the separation tank 309, the gaseous substance is cooled into liquid substance, and finally discharged through the discharge pipe 313, while the exhaust gas is filtered by the filter element 308 and enters the interior of the threaded groove 306, and finally discharged outwardly through the air outlet pipe 304.

[0037] In one embodiment, Figure 6As shown, a first water tank 310 is provided on the inner wall of the separation tank 309, and a first water inlet pipe 311 and a first water outlet pipe 312 are fixedly installed on the outside of the separation tank 309, and the first water outlet pipe 312 is located above the first water inlet pipe 311. Cold water is injected into the first water tank 310 through the first water inlet pipe 311. After the cold water fills the first water tank 310, it is discharged through the first water outlet pipe 312. The discharged water is cooled and then introduced into the first water tank 310 again through the first water inlet pipe 311, forming a cold water circulation, which effectively reduces the temperature inside the separation tank 309 and cools the gaseous substance into liquid substance.

[0038] In one embodiment, Figure 1 As shown, a sampling tube 4 is fixedly installed on the outside of the reaction tank 1, and the sampling tube 4 is located below the connecting mechanism 2. The bottom of the sampling tube 4 is threadedly connected to a sampling bottle 5. When the distillation is completed, the valve of the sampling tube 4 is opened to allow the internal solvent to enter the interior of the sampling bottle 5. After the valve is closed, the sampling bottle 5 is removed to test the solvent to determine whether the solvent still contains the substance to be extracted. If not, the solvent is discharged through the discharge pipe 10.

[0039] In one embodiment, Figure 1 and Figure 7 As shown, the stirring mechanism 7 includes a motor 701, and the motor 701 is fixedly installed at the top center point of the top cover 6. The output end of the motor 701 is connected to a transmission shaft 702, and the transmission shaft 702 is located inside the reaction tank 1. The external equidistant key grooves of the transmission shaft 702 are connected to stirring blades 703. The motor 701 drives the transmission shaft 702 to rotate, and the rotation of the transmission shaft 702 drives the stirring blades 703 to rotate, thereby effectively stirring the solvent and ensuring the uniformity of heating.

[0040] In one embodiment, Figure 1 and Figure 7 As shown, the heating mechanism 9 includes an electrical interface 901, and the electrical interface 901 is fixedly installed at an equal distance on the top of the top cover 6. The bottom end of the electrical interface 901 is electrically connected to a heating rod 902, and the heating rod 902 is located inside the reaction tank 1. The electrical interface 901 is connected to a power source, and the heating rod 902 is powered through the electrical interface 901 to generate heat, thereby heating the solvent to reach a specified temperature.

[0041] The working principle of the present invention is: the aromatic hydrocarbon mixture refers to a mixture of various aromatic hydrocarbons such as benzene, toluene, and xylene. Since these compounds have similar physical and chemical properties but different boiling points, the substances are volatilized into gases for separation by heating the solvent to different temperatures. First, hot water is injected into the second water tank 13 through the second water inlet pipe 11. After the hot water fills the second water tank 13, it is discharged through the second water outlet pipe 12. The discharged water is heated again and introduced into the second water tank 13 through the second water inlet pipe 11 to complete the circulation of hot water. The mixed aromatic hydrocarbon solvent in the reaction tank 1 can be heated by the hot water, and then the mixed aromatic hydrocarbon solvent can be quickly heated by the heating mechanism 9. When the agent temperature reaches between 80.1°C and 110.6°C, a large amount of benzene evaporates. The benzene gas enters the interior of the discharging mechanism 3 through the connecting mechanism 2, and cold water is injected into the interior of the first water tank 310 through the first water inlet pipe 311. After the cold water fills the first water tank 310, it is discharged through the first water outlet pipe 312. The discharged water is cooled and then introduced into the interior of the first water tank 310 again through the first water inlet pipe 311, forming a cold water circulation, which effectively reduces the temperature inside the separation tank 309, so that the gaseous benzene is cooled and turned into liquid benzene, and finally discharged through the discharge pipe 313, while the exhaust gas enters the interior of the threaded groove 306 through the filtration of the filter element 308, and is finally discharged to the outside through the air outlet pipe 304.

[0042] The mixed aromatic solvent is then heated to a temperature between 110.6°C and 137°C, toluene is volatilized in large quantities, and the toluene is separated and collected by the above method.

[0043] Finally, the temperature of the mixed aromatic solvent is heated to between 137° C. and 144° C., and a large amount of xylene is volatilized. The xylene is separated and collected by the above method to complete the distillation separation of the mixed aromatic solvent.

[0044] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
