[0035] Please see Figure 1-4 This utility model provides a new technical solution: a convenient and portable experimental device for the synthesis of high-purity methylal, comprising a distillation column body 1, a feed pipe 2 and a water outlet pipe 3 fixedly connected to the rear side of the distillation column body 1, the feed pipe 2 and the water outlet pipe 3 being arranged vertically and both communicating with the interior of the distillation column body 1, a steam inlet pipe 4 fixedly connected to the rear side of the distillation column body 1, the steam inlet pipe 4 communicating with the interior of the distillation column body 1, and a top cover 5 installed on the upper side of the distillation column body 1. A steam outlet pipe 6 is fixedly connected to the upper side of the distillation column body 1. The steam outlet pipe 6 is connected to the interior of the top cover 5. A fixed base 7 is fixedly fitted onto the outer surface of the distillation column body 1. The fixed base 7 is located below the water outlet pipe 3. A moving mechanism is provided on the fixed base 7. The device can be moved easily and conveniently through the moving mechanism. The moving mechanism includes a sliding groove 8, a sliding block 9, two connection ports 10, four moving wheel assemblies 11, a transmission groove 12, four rotating rods 13, four threaded rods 14, four synchronous pulleys 15, and a motor assembly 17.

[0036] Furthermore, a sliding groove 8 is formed inside the fixed base 7. The sliding groove 8 has a U-shaped groove structure. A sliding block 9 is slidably connected inside the sliding groove 8. Two connection ports 10 are both formed on the lower side of the fixed base 7, and the upper sides of the two connection ports 10 extend into the sliding groove 8. The two connection ports 10 are respectively set on the left and right sides of the distillation column body 1. Four moving wheel assemblies 11 are all fixedly connected inside the sliding block 9. The four moving wheel assemblies 11 are arranged in a rectangular array. The two moving wheel assemblies 11 on the left extend out of the fixed base 7 through the left connection port 10, and the two moving wheel assemblies 11 on the right extend out of the fixed base 7 through the right connection port 10. A transmission groove 12 is formed inside the fixed base 7. The transmission groove 12 also has a U-shaped groove structure. The transmission groove 12 is set on the upper side of the sliding groove 8. All four rotating rods 13 are rotatably connected to the top wall of the transmission groove 12. The lower ends of the four rotating rods 13 extend into the interior of the sliding groove 8. The four threaded rods 14 are fixedly connected to the lower ends of the four rotating rods 13. The lower ends of the four threaded rods 14 are threaded through the sliding block 9. The lower ends of the four threaded rods 14 are rotatably connected to the bottom wall of the sliding groove 8. The four synchronous pulleys 15 are fixedly sleeved on the outer surfaces of the four rotating rods 13. The four synchronous pulleys 15 are all located inside the transmission groove 12. The four synchronous pulleys 15 are connected by a synchronous belt 16. The motor assembly 17 is fixedly connected to the upper side of the fixed base 7. The output end of the motor assembly 17 is fixedly connected to a transmission shaft. The lower end of the transmission shaft extends into the interior of the fixed base 7. The lower end of the transmission shaft is fixedly connected to the left front rotating rod 13.

[0037] Furthermore, when starting work and needing to move the device, the operator starts the motor assembly 17. The motor assembly 17 transmits power from the output end, driving the drive shaft to rotate. The drive shaft drives the left front rotating rod 13 to rotate synchronously. The left front rotating rod 13 drives the left front synchronous pulley 15 to rotate synchronously. The left front synchronous pulley 15 drives the other three synchronous pulleys 15 to rotate synchronously via the synchronous belt 16. The other three synchronous pulleys 15 drive the other three rotating rods 13 to rotate synchronously. In turn, the four rotating rods 13 drive the four threaded rods 14 to rotate synchronously. In turn, the four threaded rods 14 drive the threaded sliding block 9 downward. The four moving wheel assemblies 11 on the lower side of the sliding block 9 will move out through the two connection ports 10, allowing the user to move the device using the four moving wheel assemblies 11. When using the device, as mentioned above, the motor assembly 17 is started in the opposite direction, and the four moving wheel assemblies 11 will move into the sliding groove 8, so that the lower side of the distillation column body 1 and the lower side of the fixed base 7 can contact the ground, thus ensuring the stability of the device during use. During use, materials are added into the interior of the distillation column body 1 through the feed pipe 2, and steam enters the interior of the distillation column body 1 through the steam inlet pipe 4, thereby performing distillation on the materials.

[0038] Furthermore, this method improves the ease of moving the distillation apparatus, allowing users to easily move it to or remove it from the experimental area, thus enhancing user convenience.

[0039] Structural Description: Distillation Column Body 1: As the core container for distillation operations, it provides space and environment for material distillation, enabling the separation and purification of different components within the column. In the methyl acetal synthesis experiment, the material undergoes distillation within Distillation Column Body 1 to achieve the synthesis of high-purity methyl acetal.

[0040] Feed pipe 2: Connected to the interior of the distillation column body 1, it is used to add the material to be distilled into the distillation column body 1, serving as the channel for the material to enter the distillation column body 1. Researchers use feed pipe 2 to transport the raw materials required for the synthesis of methyl acetal into the distillation column body 1.

[0041] Water outlet pipe 3: Also connected to the interior of the distillation column body 1, it is used to discharge water or other by-products generated during the distillation process, maintaining the material balance within the distillation column body 1 and ensuring the normal operation of the distillation process. During the distillation process, by-products such as water will be discharged through water outlet pipe 3 to prevent them from accumulating inside the column and affecting the distillation effect.

[0042] Steam inlet pipe 4: Connected to the interior of the distillation column body 1, it is used to introduce steam into the distillation column body 1. The steam serves as a heat source to provide heat for the distillation process, causing the different components in the material to vaporize, thereby achieving separation. The steam introduced through the steam inlet pipe 4 ensures that the temperature inside the distillation column body 1 reaches a suitable level, guaranteeing the progress of the distillation reaction.

[0043] Top cover 5: Installed on the upper side of the distillation column body 1, it serves a sealing function to prevent gas leakage inside the distillation column body 1. At the same time, the interior of the top cover 5 is connected to the steam outlet pipe 6, providing a channel for steam discharge. The sealing function of the top cover 5 ensures a relatively stable environment inside the distillation column body 1, which is beneficial to distillation operation.

[0044] Steam outlet pipe 6: Connected to the interior of the top cover 5, it is used to discharge the steam generated after distillation inside the distillation column body 1 for further processing or collection. The steam after distillation in the distillation column body 1 carries specific components and, after being discharged through the steam outlet pipe 6, can be subjected to subsequent condensation, separation, and other operations to obtain products such as high-purity methylal.

[0045] Fixed base 7: Fixedly sleeved on the outer surface of the distillation column body 1, located below the outlet pipe 3, providing support for the distillation column body 1. Simultaneously, the movable mechanism mounted on it facilitates the movement of the apparatus. The fixed base 7 ensures the stable placement of the entire experimental apparatus, and its supporting movable mechanism can meet the needs of transferring the apparatus between different experimental areas.

[0046] Sliding groove 8: Located inside the fixed base 7, it is a U-shaped groove structure in which the sliding block 9 slides, providing sliding space for the lifting and lowering of the moving wheel assembly 11. The structural design of the sliding groove 8 enables the sliding block 9 to move along a predetermined trajectory, ensuring the stability of the lifting and lowering of the moving wheel assembly 11.

[0047] Sliding block 9: Slidingly connected inside the sliding groove 8, with four movable wheel assemblies 11 fixedly connected inside. By sliding within the sliding groove 8, the movable wheel assemblies 11 can extend and retract. When the device needs to be moved, the sliding block 9 moves downward, causing the movable wheel assemblies 11 to extend out of the fixed base 7; when the device needs to be fixed for use, the sliding block 9 moves upward, causing the movable wheel assemblies 11 to retract.

[0048] Connection ports 10: Two ports are located on the lower side of the fixed base 7, one on the left and one on the right side of the distillation column body 1. Both ports extend into the sliding groove 8. The two moving wheel assemblies 11 on the left extend out of the fixed base 7 through the left connection port 10, and the two moving wheel assemblies 11 on the right extend out of the fixed base 7 through the right connection port 10. These ports provide a path for the moving wheel assemblies 11 to move, allowing them to smoothly extend and retract from the fixed base 7.

[0049] Moving wheel assembly 11: There are four moving wheel assemblies 11 in total, which are fixedly connected inside the sliding block 9 in a rectangular array. When the sliding block 9 drives the moving wheel assembly 11 to extend out of the fixed base 7, the device can be moved on the ground, making it convenient for users to move the device to or from the experimental area. The moving wheel assembly 11 reduces the friction between the device and the ground, making the movement of the device easier and more convenient.

[0050] Transmission groove 12: Located inside the fixed base 7, it also has a U-shaped groove structure and is positioned above the sliding groove 8. It provides installation and movement space for transmission components such as the rotating rod 13, synchronous pulley 15, and synchronous belt 16. The structural design of transmission groove 12 enables the orderly installation and normal operation of each transmission component, ensuring the stability of power transmission.

[0051] Rotating rods 13: There are four rotating rods 13 in total, all rotatably connected to the top wall of the transmission groove 12. The lower ends of each rod extend into the interior of the sliding groove 8. Their rotation can drive the threaded rod 14 to rotate synchronously, thereby realizing the lifting and lowering of the sliding block 9. The rotating rods 13 play an intermediate transmission role in the transmission process, transmitting the power transmitted by the motor assembly 17 to the threaded rod 14.

[0052] Threaded rods 14: There are four threaded rods 14, each fixedly connected to the lower end of one of the four rotating rods 13. The lower end of each rod is threaded through the sliding block 9 and rotatably connected to the bottom wall of the sliding groove 8. Rotation of the threaded rods 14 causes the threaded sliding blocks 9 to move up and down within the sliding groove 8. The threaded connection between the threaded rods 14 and the sliding blocks 9 converts the rotational motion of the rotating rods 13 into the linear motion of the sliding blocks 9, thus achieving the lifting and lowering of the moving wheel assembly 11.

[0053] Synchronous pulleys 15: There are four synchronous pulleys 15, each fixedly sleeved on the outer surface of one of the four rotating rods 13. They are all located inside the transmission groove 12. The four synchronous pulleys 15 are connected by a synchronous belt 16. When the left front synchronous pulley 15 rotates, it drives the other three synchronous pulleys 15 to rotate synchronously via the synchronous belt 16, thus achieving synchronous rotation of the four rotating rods 13. The cooperation between the synchronous pulleys 15 and the synchronous belt 16 ensures that the four rotating rods 13 can rotate synchronously and stably, making the lifting and lowering of the sliding block 9 more smooth.

[0054] Synchronous belt 16: Connected between the four synchronous pulleys 15, it transmits power, enabling the four pulleys 15 to rotate synchronously, thereby ensuring the synchronous rotation of the four rotating rods 13 and the four threaded rods 14. Synchronous belt 16 improves the efficiency and stability of power transmission, avoiding problems such as jamming of the sliding block 9 caused by asynchronous rotation of the four rotating rods 13.

[0055] Motor assembly 17: Fixedly connected to the upper side of the fixed base 7, its output end is fixedly connected to a drive shaft. The lower end of the drive shaft extends rotatably into the interior of the fixed base 7 and is fixedly connected to the left front rotating rod 13. When the motor assembly 17 is started, power is transmitted from the output end, driving the drive shaft to rotate, which in turn drives the left front rotating rod 13 to rotate, providing a power source for the lifting and lowering of the moving wheel assembly 11. The motor assembly 17 is the power core of the entire moving mechanism, realizing the movement and fixing functions of the device through electric drive.

[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
