Description

Technical Field

[0001] This utility model relates to the technical field of environmentally friendly hexane purification equipment, specifically an environmentally friendly hexane purification equipment that can improve the purification degree. Background Technology

[0002] The environmentally friendly hexane purification unit is a chemical equipment specifically designed for the separation and purification of industrial-grade hexane. Its core function is to improve the purity of hexane through efficient separation technology. It uses electric heating plates combined with heat-conducting plates for uniform heat transfer, which vaporizes the crude hexane and avoids local overheating that could lead to decomposition. Through a multi-stage distillation and dynamic filtration system, crude hexane can be purified to ≥99% n-hexane or isohexane.

[0003] However, most environmentally friendly hexane purification devices require contact mixing with sulfuric acid before use. Typically, a single stirring rod is used for stirring, resulting in a slow stirring speed and poor mixing between sulfuric acid and hexane. Consequently, the purification effect of environmentally friendly hexane is poor. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly hexane purification device that can improve the purity of the purified hexane, thereby solving the problem of slow stirring speed of sulfuric acid and hexane in the environmentally friendly hexane purification devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly hexane purification device that can improve purification efficiency, comprising a first tank, a second tank, a distillation tank, and connecting pipes. The second tank is disposed on one side of the first tank, and the distillation tank is disposed on the side of the second tank away from the first tank. Connecting pipes connect the distillation tank, the second tank, and the first tank. Symmetrically distributed filling ports are disposed at the top of the first tank. A fixing frame is disposed on one side of each filling port. A drive motor is mounted at the top of the fixing frame. The output end of the drive motor is connected to a first rotating rod via a coupling.

[0006] Preferably, a rotating rod connected by a bearing is provided inside the fixed frame on the side near the first rotating rod, and a gear set is provided between the rotating rod and the first rotating rod for meshing connection. A second rotating rod connected by a bearing is provided on the side of the rotating rod away from the first rotating rod.

[0007] Preferably, a pulley assembly is connected between the second rotating rod and the rotating rod, and uniformly distributed stirring plates are provided between the second rotating rod and the first rotating rod.

[0008] Preferably, the first tank has a discharge port on the side away from the second tank.

[0009] Preferably, the interior of the second tank is provided with a uniformly distributed column of sodium hydroxide alkali, a heating plate is installed at the bottom of the interior of the distillation tank, a protective frame is provided at the top of the distillation tank, a connecting pipe is connected between the protective frame and the distillation tank, and another connecting pipe is connected to the top of the protective frame.

[0010] Preferably, a mounting plate is provided on one side of the protective frame, and symmetrically distributed activated carbon plates are provided on one side of the mounting plate. Positioning plates are provided on both sides of the interior of the protective frame near the activated carbon plates, and symmetrically distributed positioning blocks are provided on the side of the protective frame near the mounting plate.

[0011] Preferably, an adjustment frame is provided on the side of the mounting plate near the positioning block, and symmetrically distributed pinch plates are provided on one side of the adjustment frame.

[0012] Preferably, one end of each of the two pinch plates is connected to a limiting rod, and one end of each of the two limiting rods is connected to a limiting spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This environmentally friendly hexane purification device, which can improve the purity, starts the drive motor so that the first and second rotating rods can stir and mix sulfuric acid and hexane through the stirring plate. Since they rotate in opposite directions, the mixing effect during stirring is improved. Therefore, the environmentally friendly hexane purification device can accelerate the contact between sulfuric acid and hexane during operation, thereby improving the purification effect. By installing the mounting plate along with the activated carbon plate inside the protective frame along the positioning plate, the activated carbon plate filters the distilled gas, thereby removing large molecular impurities. This allows the environmentally friendly hexane purification device to have a better filtration and purification effect during operation.

[0014] 1. This environmentally friendly hexane purification device, which improves purification efficiency, typically operates slowly when mixing and stirring with sulfuric acid, affecting the purification effect. This can be improved by adding sulfuric acid and hexane separately through the inlet, followed by starting the drive motor after addition. This allows the drive motor to rotate the first rotating rod connected to the output end. The first rotating rod, in turn, rotates a rotating rod on one side via a gear set. This rotating rod, in turn, rotates a second rotating rod via a pulley set. The second rotating rod rotates in the opposite direction to the first, thus stimulating the stirring surfaces on both the first and second rotating rods. The plates rotate in opposite directions, which improves the stirring and mixing of sulfuric acid and hexane inside the first tank, allowing for rapid stirring. After stirring, the sediment at the bottom is discharged, and the purified hexane inside the first tank is drawn through a connecting pipe equipped with a pump, allowing it to flow into the second tank and come into contact with the sodium hydroxide column. The pumping allows the hexane to be purified multiple times in the first and second tanks, resulting in a higher purity after subsequent purification. Then, distillation is carried out in the distillation tank to obtain environmentally friendly hexane with a higher concentration. Thus, the environmentally friendly hexane purification device can accelerate the contact between sulfuric acid and hexane during operation, thereby improving the purification effect.

[0015] 2. This environmentally friendly hexane purification device, which improves purity, addresses the issue that slight impurities may remain during distillation, affecting the final purity. By squeezing two pinch plates, the device moves a connected limiting rod, which in turn compresses a limiting spring on one side. The limiting rod then retracts into the adjusting frame, moving the mounting plate and allowing it to install an activated carbon plate along the positioning plate into the protective frame. The mounting plate then engages with the positioning block. Loosening the pinch plates releases the limiting spring, causing it to reset the limiting rod and fix it to the positioning block. This fixes the mounting plate, allowing the activated carbon plate to filter the distilled gas, removing large molecular impurities. This results in a more effective filtration and purification process for the environmentally friendly hexane purification device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3This utility model provides a technical solution: an environmentally friendly hexane purification device that can improve purification efficiency, comprising a first tank 1, a second tank 2, a distillation tank 3, and a connecting pipe 4. The second tank 2 is located on one side of the first tank 1, and the distillation tank 3 is located on the side of the second tank 2 away from the first tank 1. Connecting pipes 4 connect the distillation tank 3, the second tank 2, and the first tank 1. Symmetrically distributed filling ports 5 are located at the top of the first tank 1. A fixing frame 6 is located on one side of each filling port 5, and a drive motor 7 is mounted on the top of the fixing frame 6. The drive motor 7... The outlet is connected to a first rotating rod 8 via a coupling. Inside the fixed frame 6, a rotating rod 9 connected by a bearing is provided on the side near the first rotating rod 8. A gear set 10 is provided between the rotating rod 9 and the first rotating rod 8. A second rotating rod 11 connected by a bearing is provided on the side of the rotating rod 9 away from the first rotating rod 8. A pulley set 12 is connected between the second rotating rod 11 and the rotating rod 9. A uniformly distributed stirring plate 13 is provided between the second rotating rod 11 and the first rotating rod 8. A discharge port 14 is provided on the side of the first tank 1 away from the second tank 2.

[0025] In practice,

[0026] See Figures 1-3 It is known that when the environmentally friendly hexane purification device is in use, the mixing speed with sulfuric acid is usually slow, which affects the purification effect of hexane. This can be addressed by adding sulfuric acid and hexane separately through the filling port 5, and then starting the drive motor 7 after the filling is completed. This allows the drive motor 7 to rotate the first rotating rod 8 connected to the output end. When the first rotating rod 8 rotates, it can rotate the rotating rod 9 on one side through the gear set 10. In turn, the rotating rod 9 rotates, which in turn rotates the pulley set 12 connected to the surface. This allows the pulley set 12 to rotate, which in turn rotates the second rotating rod 11 connected to the other side. At this time, the rotation direction of the second rotating rod 11 is opposite to that of the first rotating rod 8, so that the first rotating rod 8 and the second rotating rod 11 rotate in opposite directions. The stirring plates 13 on the surface of the rotating rod 11 rotate in opposite directions, which improves the stirring and mixing of sulfuric acid and hexane inside the first tank 1, enabling rapid stirring. After stirring, the sediment at the bottom is discharged after settling. The purified hexane inside the first tank 1 is then drawn out through the connecting pipe 4 equipped with a pump, allowing it to flow into the second tank 2 and come into contact with the sodium hydroxide column 15. The pumping allows the hexane to be repeatedly purified multiple times in the first tank 1 and the second tank 2, resulting in a higher purity after subsequent purification. Then, distillation is performed in the distillation tank 3 to obtain environmentally friendly hexane with a higher concentration. Thus, the environmentally friendly hexane purification device can accelerate the contact between sulfuric acid and hexane during operation, thereby improving the purification effect.

[0027] The second tank 2 has a uniformly distributed sodium hydroxide alkali column 15 inside. The bottom of the distillation tank 3 is equipped with a heating plate 16. The top of the distillation tank 3 is equipped with a protective frame 17. A connecting pipe 18 connects the protective frame 17 and the distillation tank 3. Another connecting pipe 18 is connected to the top of the protective frame 17. A mounting plate 19 is provided on one side of the protective frame 17. A symmetrically distributed activated carbon plate 20 is provided on one side of the mounting plate 19. Positioning plates 21 are provided on both sides of the protective frame 17 near the activated carbon plate 20. A symmetrically distributed positioning block 22 is provided on the side of the protective frame 17 near the mounting plate 19. An adjusting frame 23 is provided on the side of the mounting plate 19 near the positioning block 22. A symmetrically distributed pinch plate 24 is provided on one side of the adjusting frame 23. A limit rod 25 is connected to one end of each pinch plate 24. A limiting spring 26 is connected to one end of each limit rod 25.

[0028] In practice,

[0029] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 It is known that when the environmentally friendly hexane purification device is distilling, it may still contain slight impurities, affecting the final purity. This can be addressed by squeezing the two pinch plates 24, which move the connected limiting rod 25. As the limiting rod 25 moves, it compresses the limiting spring 26 connected to one side, and the limiting rod 25 is retracted into the adjusting frame 23. This, in turn, moves the mounting plate 19, causing the activated carbon plate 20 on one side to be installed into the protective frame 17 along the positioning plate 21. Internally, the mounting plate 19 can be inserted into the positioning block 22. Then, the pinched plate 24 is loosened, so that the limiting spring 26 can lose its restraint. In turn, the limiting spring 26 can drive the limiting rod 25 to reset, so that the limiting rod 25 can limit the positioning block 22, thereby fixing the position of the mounting plate 19. This allows the distilled gas to be filtered through the activated carbon plate 20, thereby removing large molecular impurities. This ensures that the environmentally friendly hexane purification device has a good filtration and purification effect during operation.

[0030] In summary, the environmentally friendly hexane purification device is a chemical equipment specifically designed for the separation and purification of industrial-grade hexane. Its core function is to improve the purity of hexane through efficient separation technology. Starting the drive motor 7 allows the first rotating rod 8 and the second rotating rod 11 to mix sulfuric acid and hexane via the stirring plate 13. Since they rotate in opposite directions, the mixing effect is enhanced. This allows the environmentally friendly hexane purification device to accelerate the contact between sulfuric acid and hexane during operation, thereby improving the purification effect.
