Description

Technical Field

[0001] This utility model relates to the field of methanol production technology, and in particular to a methanol synthesis apparatus for methanol production. Background Technology

[0002] Methanol is a colorless, transparent liquid that is volatile and miscible with water. Although it has an odor similar to ethanol, it is highly toxic and can cause serious harm to the human body if ingested. Its applications are extensive. In the chemical industry, it serves as a basic raw material for the production of chemical products such as formaldehyde, acetic acid, and polyoxymethylene. In the energy sector, it can be used as fuel for ships and trucks or blended with gasoline. It can also be used to produce hydrogen through cracking, serving as a hydrogen energy carrier, and can be used for storing electrical energy as chemical energy in grid peak shaving. Furthermore, it can be used as a solvent, antifreeze, and steel desulfurizing agent, playing an important role in multiple industries such as pharmaceuticals, pesticides, and metallurgy. It is a key substance with dual properties as both a chemical raw material and an energy carrier.

[0003] Currently, traditional methanol synthesis plants mostly adopt a production mode of mixing raw materials and catalysts for reaction. During the synthesis process, if the catalyst supply is insufficient, it needs to be added manually. This operation requires employees to be in close contact with the reactor. Methanol synthesis reaction is not only accompanied by high temperature and high pressure conditions, but also releases toxic and harmful gases. Frequent manual addition of catalyst significantly increases the occupational health risks for employees. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a methanol synthesis apparatus for methanol production, which aims to improve the problems in the prior art where the catalyst cannot be automatically added when it is insufficient, and where the catalyst and raw materials are not mixed sufficiently.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A methanol synthesis apparatus for methanol production includes a reactor, a feed pipe fixedly connected to the top of the reactor, a cover plate provided on the top of the feed pipe, a support fixedly connected to the outer periphery of the reactor, an outer shell fixedly connected to the bottom of the reactor, an addition component provided inside the feed pipe, and a drive component provided inside the outer shell. The added component includes an electric push rod, the bottom of which is fixedly connected to the top of the reactor. A temporary storage frame is fixedly connected to the output end of the electric push rod. A baffle is fixedly connected to the top of the temporary storage frame. A baffle is rotatably connected to the bottom of the temporary storage frame. Two inclined blocks are fixedly connected inside the feeding pipe. The temporary storage frame is slidably connected between the two inclined blocks. A partition is fixedly connected inside the feeding pipe. As a further description of the above technical solution: The drive assembly includes a motor, which is fixedly connected to the bottom of the outer casing. A rotating rod 2 is fixedly connected to the output end of the motor. A bevel gear 2 is fixedly connected to the outer periphery of the rotating rod 2. A stirring rod 1 is fixedly connected to the top end of the rotating rod 2. A connecting rod is rotatably connected to the inner wall of the outer casing. A bevel gear 1 is fixedly connected to the end of the connecting rod away from the outer casing. The bevel gear 1 and the bevel gear 2 are meshed together. A rotating rod 1 is rotatably connected to the outer wall of the rotating rod 2. A bevel gear 3 is fixedly connected to the bottom end of the rotating rod 1. The bevel gear 3 is meshed with the bevel gear 1. A stirring rod 2 is fixedly connected to the top end of the rotating rod 1. As a further description of the above technical solution: The outer side of the baffle is slidably connected to the inside of the feed pipe, and the end of the baffle near the temporary storage frame is slidably connected to the inner side of the partition. As a further description of the above technical solution: The temporary storage frame passes through and is slidably connected to the inner side of the partition, and the second baffle abuts against the feed pipe; As a further description of the above technical solution: An exhaust pipe is fixedly connected to the top of the reactor, and a drain pipe is fixedly connected to the outside of the reactor. As a further description of the above technical solution: A scraper is fixedly connected to one side of the rotating rod, and the scraper is slidably connected to the inner wall of the reactor. As a further description of the above technical solution: The bottom of the second rotating rod is rotatably connected to the inside of the outer shell, and the first rotating rod passes through and is rotatably connected to the inside of the reaction vessel; As a further description of the above technical solution: A handle is fixedly connected to the top of the cover plate.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the temporary storage frame is pushed outward by an electric push rod. After the temporary storage frame slides to a specific position, the feed pipe no longer supports the second baffle. Under the action of the catalyst's own weight, the second baffle automatically flips, allowing the catalyst to fall accurately into the reactor. No manual intervention is required throughout the process, effectively avoiding operational risks. At the same time, during the outward movement of the temporary storage frame, the first baffle moves synchronously, forming a dynamic barrier structure to prevent the catalyst from falling outside the temporary storage frame during the addition process. After all the catalyst in the temporary storage frame has been added, the electric push rod reverses and moves the temporary storage frame, and the second baffle resets, preparing for the next addition. This ensures that the catalyst replenishment process is efficient, continuous, and requires no manual intervention.

[0007] 2. In this utility model, the rotating rod 2 is driven to rotate by a motor, which in turn drives the bevel gear 2 to rotate synchronously. Since the bevel gear 1 meshes with both the bevel gear 2 and the bevel gear 3, the rotation of the bevel gear 2 is transmitted through the bevel gear 1, which drives the bevel gear 3 and the rotating rod 1 to rotate in the opposite direction. This results in the stirring rod 1 and the stirring rod 2 forming a dynamic stirring mode of opposite rotation. Through bidirectional shearing and convection, the mixing effect of the raw materials and the catalyst is greatly enhanced, and the efficiency of the methanol synthesis reaction is significantly improved.

[0010] 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.

[0011] Reference Figures 1-3The present invention provides an embodiment of a methanol synthesis apparatus for methanol production, comprising a reactor 1, a feed pipe 4 fixedly connected to the top of the reactor 1, a cover plate 3 provided on the top of the feed pipe 4, by opening the cover plate 3, pouring raw materials and catalyst into the reactor 1, and then mixing and stirring to produce methanol, a support 2 fixedly connected to the outer periphery of the reactor 1, the support 2 being used to support the reactor 1 so that the reactor 1 can operate stably, an outer shell 23 fixedly connected to the bottom of the reactor 1, an adding component being provided inside the feed pipe 4, the adding component being used to automatically add catalyst, and a driving component being provided inside the outer shell 23, the driving component being used to accelerate the mixing rate of raw materials and catalyst, so that the two are mixed more thoroughly; The added components include an electric push rod 9, whose bottom is fixedly connected to the top of the reactor 1. A temporary storage frame 12 is fixedly connected to the output end of the electric push rod 9. A baffle 8 is fixedly connected to the top of the temporary storage frame 12, and a second baffle 13 is rotatably connected to the bottom of the temporary storage frame 12. Two inclined blocks 11 are fixedly connected inside the feed pipe 4, and the temporary storage frame 12 is slidably connected between the two inclined blocks 11. A partition 10 is fixedly connected inside the feed pipe 4. When catalyst is added to the feed pipe 4, the catalyst slides into the temporary storage frame 12 due to the action of the inclined blocks 11. When catalyst needs to be replenished, the electric push rod 9 is activated, causing its output end to move the temporary storage frame 12 outwards. When the temporary storage frame moves to a certain extent, the second baffle 13 will lack support. At this time, the weight of the catalyst will act on the top of the second baffle 13, causing the second baffle 13 to rotate downwards, and then the catalyst will fall downwards. When all the catalyst in the temporary storage frame 12 has slid out, the electric push rod 9 drives the temporary storage frame 12 to move in the opposite direction. At this time, the second baffle 13 will slowly contact the bottom of the feed pipe 4, thereby resetting the second baffle 13 and facilitating the next addition operation. Furthermore, a first baffle 8 is set on the top of the temporary storage frame 12. As the temporary storage frame 12 moves outwards, the first baffle 8 will move synchronously, thereby preventing the catalyst from falling into the outside of the temporary storage frame 12. Reference Figure 1 and Figure 4The drive assembly includes a motor 6, which is fixedly connected to the bottom of the outer casing 23. A rotating rod 19 is fixedly connected to the output end of the motor 6. A bevel gear 16 is fixedly connected to the outer periphery of the rotating rod 19. A stirring rod 20 is fixedly connected to the top of the rotating rod 19. A connecting rod 14 is rotatably connected to the inner wall of the outer casing 23. A bevel gear 15 is fixedly connected to the end of the connecting rod 14 away from the outer casing 23. The bevel gear 15 and the bevel gear 16 are meshed together. A rotating rod 18 is rotatably connected to the outer wall of the rotating rod 19. The bottom end of the rotating rod 18 is fixedly connected to the outer wall of the rotating rod 19. A bevel gear 17 is fixedly connected to the top of a rotating rod 18, which meshes with a bevel gear 15. A stirring rod 21 is fixedly connected to the top of the rotating rod 18. When the motor 6 is started, the motor 6 can convert electrical energy into mechanical kinetic energy, thereby driving the rotating rod 29 and the bevel gear 26 to rotate together. Then, through the transmission of the bevel gear 15, the bevel gear 17 and the rotating rod 18 are driven to rotate in the opposite direction, which in turn causes the stirring rod 20 and the stirring rod 21 to rotate in the opposite direction as well. This allows the catalyst and raw materials to be fully mixed, increasing the methanol production efficiency. Reference Figure 2 and Figure 3 The outer side of the baffle 8 is slidably connected to the inside of the feed pipe 4, and the end of the baffle 8 near the temporary storage frame 12 is slidably connected to the inner side of the partition 10. When the temporary storage frame 12 moves, it will drive the baffle 8 to move synchronously, thereby preventing the catalyst from sliding down. Reference Figure 2 and Figure 3 The temporary storage frame 12 is slidably connected to the inner side of the partition 10. The second baffle 13 abuts against the feed pipe 4. When the temporary storage frame 12 moves through the partition 10, it will drive the second baffle 13 to move synchronously. When the second baffle 13 slides away from the feed pipe 4, it will rotate downward due to the gravity of the catalyst, thereby automatically adding the catalyst. When the temporary storage frame 12 is reset, the second baffle 13 will contact the feed pipe 4, thereby resetting the second baffle 13. Reference Figure 1 The top of the reactor 1 is fixedly connected to an exhaust pipe 5. Some gas will be generated during the methanol production process. If it is not discharged in time, the internal pressure of the reactor 1 will increase. Therefore, it is necessary to discharge the gas in time to ensure the safety and reliability of the production process. The discharged gas needs to be treated before being discharged into the air to avoid polluting the air. The outside of the reactor 1 is fixedly connected to a drain pipe 7. After the methanol production is completed, it will be discharged from the drain pipe 7. Reference Figure 4 A scraper 22 is fixedly connected to the outside of the rotating rod 18. The scraper 22 is slidably connected to the inner wall of the reactor 1. The scraper 22 is used to scrape off the residual material on the inner wall of the reactor 1, thereby reducing resource waste. Reference Figure 4The bottom of the rotating rod 19 is rotatably connected to the inside of the outer shell 23, and the rotating rod 18 passes through and is rotatably connected to the inside of the reactor 1. When the rotating rod 19 is driven, it will rotate inside the outer shell 23, and then indirectly drive the rotating rod 18 to rotate inside the reactor 1. Reference Figure 1 A handle 24 is fixedly connected to the top of the cover plate 3. By setting the handle 24, the cover plate 3 can be opened quickly.

[0012] Working principle: First, open the cover plate 3, add raw materials and catalyst to the feed pipe 4, and then add a certain amount of catalyst between the two inclined blocks 11 to replenish the catalyst. When catalyst needs to be replenished, start the electric push rod 9. The output end of the electric push rod 9 will push the temporary storage frame 12 to slide outward. When it slides to a certain extent, the bottom of the feed pipe 4 will no longer support the baffle 13. At this time, the baffle 13 will rotate downward due to the gravity of the catalyst itself, so that the catalyst falls into the reactor 1, thus automatically adding the catalyst and avoiding manual addition of the catalyst. In addition, the temporary storage frame 12 will drive the baffle 8 to move together during the outward movement. The baffle 8 can prevent the catalyst from sliding down and reduce waste. After all the catalyst inside the temporary storage frame 12 has fallen into the reactor 1, the electric push rod 9 will drive the temporary storage frame 12 to retract. At this time, the baffle 13 will slowly rotate to the bottom of the temporary storage frame 12 due to contact with the feed pipe 4, so as to carry out the next addition operation.

[0013] When it is necessary to fully mix the raw materials and catalyst, start motor 6. The output of motor 6 will drive rotating rod 19 to rotate, which in turn drives bevel gear 16 to rotate. At this time, since bevel gear 15 is meshed with bevel gear 16 and bevel gear 17, bevel gear 15 will drive bevel gear 17 to rotate, which in turn drives rotating rod 18 to rotate. Therefore, stirring rod 20 and stirring rod 21 can rotate in opposite directions, so that the raw materials and catalyst are mixed more thoroughly and the methanol production efficiency is improved.

[0014] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
