Description

Technical Field

[0001] The invention belongs to the technical field of cyclopentanone preparation, and in particular relates to a production device for a cyclopentanone product. Background Art

[0002] In the prior art, the preparation of cyclopentanone generally adopts the following steps: adipic acid and barium hydroxide are uniformly mixed, and then heated within a certain temperature range. The temperature is generally between 285-295°C. At this temperature, adipic acid undergoes a decomposition reaction under the catalytic action of barium hydroxide to produce cyclopentanone. Subsequently, a distillation operation is performed to separate the produced cyclopentanone from the reaction mixture.

[0029] like Figures 1 to 9As shown, a production device of a cyclopentanone product of the present invention comprises a stirring reaction mechanism, wherein the stirring reaction mechanism comprises a hollow mounting cylinder 1, one end of the mounting cylinder 1 is closed, a support leg 3 is arranged on the outer surface of the mounting cylinder 1 facing the ground, one end of the support leg 3 is fixed to the outer surface of the mounting cylinder 1, a plurality of partitions 6 are arranged in the axial direction inside the mounting cylinder 1, the edges of the partitions 6 are in sliding contact with the inner wall of the mounting cylinder 1, an arc-shaped connecting plate 8 is arranged between adjacent partitions 6, the two side surfaces of the arc-shaped connecting plate 8 are respectively fixed to the end surfaces of two adjacently arranged partitions 6, a notch is arranged between the two ends of the arc-shaped connecting plate 8, and the notch faces the side of the mounting cylinder 1 away from the ground. The surface is arranged, and a feeding pipe 2 is provided on the installation cylinder 1 just above the notch of the arc-shaped connecting plate 8, and the feeding pipe 2 is connected to the notch. A rotating bearing 7 is provided in the middle of several partitions 6, and the outer ring of the rotating bearing 7 is fixed on the partition 6. The inner ring of the rotating bearing 7 is provided with a rotating shaft 5, and the inner ring of the bearing is fixed on the rotating shaft 5. A stirring rod 10 is provided on the rotating shaft 5 between two adjacent partitions 6, and one end of the stirring rod 10 is fixed on the rotating shaft 5. A driving motor 4 is provided on the end of the rotating shaft 5 located outside the installation cylinder 1, and the output end of the driving motor 4 is fixed on the rotating shaft 5. A sliding mechanism is provided on the unclosed end of the installation cylinder 1, and the driving motor 4 is fixed on the sliding mechanism.

[0030] The working principle of the above technical solution is:

[0031] When preparing cyclopentanone, first add barium hydroxide particles between each adjacent partition 6, and then slide the partition 6 arranged side by side into the interior of the mounting cylinder 1 so that the partition 6 at the end is tightly set against the closed end of the mounting cylinder 1. It should be noted that at this time, the gap between the ends of the arc-shaped connecting plate 8 should be set facing upward, and then a certain amount of adipic acid is added to the position between the two partitions 6 through the feeding pipe 2, and then the driving motor 4 is rotated to drive the stirring rod 10 to rotate, so as to glue the space between the adjacent partitions 6, so that the barium hydroxide and adipic acid in the area can be fully mixed and reacted.

[0032] It is not difficult to understand that this method separates a large amount of raw materials (barium hydroxide) into multiple different reaction areas (composed of adjacent reaction tanks and the arc-shaped connecting plate 8 between the two) for mixed reaction, and stirs each reaction area separately, which can improve the stirring and mixing effect and the reaction effect at the same time; this technical solution separates a large amount of raw materials into small amounts of raw materials in multiple areas in a "breakdown" manner, thereby solving the problem of raw materials being easily accumulated in traditional vertical stirring tanks, resulting in insufficient mixing.

[0033] In one practicable manner, the sliding mechanism includes a symmetrically arranged arc guide rail 14, one end of the arc guide rail 14 is fixed on the mounting cylinder 1, and the inner wall of the arc guide rail 14 is flush with the inner wall of the mounting cylinder 1, that is, it can be understood that the inner ring diameter of the arc guide rail 14 is consistent with the inner ring diameter of the mounting cylinder 1, and an installation spacing is provided between the two arc guide rails 14. A slider 15 is provided on the two arc guide rails 14, and both ends of the slider 15 are respectively slidably connected to the two arc guide rails 14. A fixed block 16 is provided on the slider 15, and the drive motor 4 is fixed on the fixed block 16. The length of the arc guide rail 14 is greater than the length of the mounting cylinder 1.

[0034] With the guidance and support of the arc guide rail 14, when installing or removing several partitions 6 in the installation cylinder 1, it is only necessary to manually pull the slider 15 to pull the partition 6 onto the arc guide rail 14. Since the inner wall of the arc guide rail 14 is flush with the inner wall of the installation cylinder 1, the guidance of the partition 6 is smoother. At the same time, an installation spacing is provided between the two arc guide rails 14. The notch can be aligned with the installation spacing by rotating the partition 6, and the product after the reaction is completed can be poured out.

[0035] In one feasible manner, a retaining ring is provided on the arc guide rail 14, and the retaining ring is detachably connected to the arc guide rail 14, and is used to block the sliding of the slider 15. The function of the retaining ring is to block the movement of the slider 15 when the drive motor 4 is working, so as to prevent the partition 6 from slipping off to the outside of the mounting cylinder 1.

[0036] In one practicable manner, two groups of symmetrically arranged communicating holes 11 are provided on the plurality of partitions 6 located in the middle, and the communicating holes 11 groups include a plurality of vertically arranged communicating holes 11, and the two groups of communicating holes 11 groups are located on both sides of the rotating shaft 5. The arrangement of the communicating holes 11 can play a connecting role, even if the pages of adipic acid in each reaction area are flush, that is, when an equal amount of barium hydroxide is added to each reaction area, when adipic acid is added, there is no need to accurately control the amount of addition to each reaction area separately, so that the amount of adipic acid added to each area can be guaranteed to be consistent. At the same time, it can be understood here that the addition of adipic acid in each area is "rounded off", and only the adipic acid required to meet the total amount of barium hydroxide needs to be added, so as to achieve rapid addition of adipic acid. Of course, the part where the cylinder 1 is installed can be transparent, so as to facilitate observation of the amount of adipic acid added.

[0037] like Figure 7-Figure 9As shown, in an implementable manner, a card plate 12 is provided on the outer side of any group of connecting holes 11, the card plate 12 is fixed on the partition 6 and is arranged near the middle of the partition 6, a plurality of baffles 13 corresponding to the positions of the connecting holes 11 are provided on the card plate 12, the baffle 13 is slidably connected to the card plate 12, and one end of the baffle 13 is arranged toward the connecting holes 11, a first magnetic block 23 is provided on the other end of the baffle 13, one end of the first magnetic block 23 is fixed on the baffle 13, and the two first magnetic blocks 23 arranged opposite to each other have different magnetic properties from the end fixed to the baffle 13, a second magnetic block 24 is provided on the outer side of the first magnetic block 23, a mounting rod 25 is provided in the middle of the second magnetic block 24, the second magnetic block 24 is rotatably connected to the mounting rod 25, and both ends of the mounting rod 25 are detachably connected to the partition 6.

[0038] The baffle 13 is provided to block and close the connecting hole 11, that is, one connecting hole 11 in the group of several vertical connecting holes 11 can be selected according to needs to remain unobstructed (selecting the height of the connecting hole 11 can also be understood as selecting the height of adding adipic acid). The advantage of this is that the connecting holes 11 at a lower position can be closed to prevent the barium hydroxide particles in each reaction area from moving through the connecting holes 11 during stirring, resulting in uneven distribution of barium hydroxide in each reaction area. At the same time, it also prevents the connecting holes 11 at a lower position from being blocked, resulting in a large amount of cleaning work in the later stage (it is not difficult to understand that the unobstructed connecting holes 11 are located above the accumulated barium hydroxide, that is, they will not be blocked during stirring).

[0039] It is not difficult to understand that the two magnetic poles of the second magnetic block 24 can respectively pull the ends of the first magnetic blocks 23 set on both sides, that is, the connecting hole 11 is in an open state at this time, and the baffle 13 at the connecting hole 11 at other positions does not need to be opened. At this time, you only need to rotate the second magnetic block 24 on the mounting rod 25 to swap the magnetic poles of the second magnetic block 24. That is, at this time, the two ends of the second magnetic pole repel the ends of the first magnetic blocks 23 on both sides, that is, push the baffle 13 to move to close the connecting hole. In this way, the position state of the baffle 13 can be guaranteed, and there will be no problem of the baffle 13 slipping on the card plate 12 due to vibration.

[0040] The sealing piston 9 is provided with a sealing piston 9 on the part of the rotating shaft 5 close to the unsealed end of the mounting cylinder 1. The middle part of the sealing piston 9 is rotatably connected to the rotating shaft 5, and the end face is fixed on the partition 6 arranged at one end. The edge of the sealing piston 9 is squeezed and contacted with the inner wall of the mounting cylinder 1 to prevent liquid leakage. The edge of the sealing piston 9 facing the mounting cylinder 1 is conical. The conical setting can guide the sealing piston 9 to enter the mounting cylinder 1 to avoid the problem that it cannot enter the mounting cylinder 1 due to its relatively large diameter. Horizontal marking lines are provided on the unsealed end of the sealing piston 9 and the mounting cylinder 1. The horizontal marking lines are convenient for positioning and adjusting the partition 6 and the arc connecting plate 8 to ensure the position accuracy of the notch. It is not difficult to understand that bolts or the like can be set on the end face of the sealing piston 9 to tighten it against the mounting cylinder 1 to prevent it from rotating due to vibration. Furthermore, the part where the partition 6 and the sealing piston 9 are rotatably connected to the rotating shaft 5 needs to be sealed, such as the shaft seal in the prior art, which will not be described in detail.

[0041] In an practicable manner, a collection box 22 is provided directly below the arc-shaped guide rail 14 , and the collection box 22 can collect the slag after the reaction.

[0042] In one practicable manner, a distillation mechanism is also included, and the distillation mechanism includes a heat transfer block 17, the upper surface of the heat transfer block 17 is in arc-shaped contact with the outer surface of the middle and lower part of the installation cylinder 1, and the interior of the heat transfer block 17 is provided with a heating wire 18, which is a prior art and will not be described in detail here. The heat transfer block 17 is in contact with the installation cylinder 1 to transfer heat, so that the heat transfer is more uniform, that is, the reaction temperature applied to the internal reactants is more uniform. At the same time, a higher temperature can be applied to achieve a distillation operation on the product after the reaction, thereby obtaining cyclopentanone. It is not difficult to find that during the distillation operation, the evaporated cyclopentanone can be discharged through the feed pipe for condensation and collection.

[0043] In one feasible manner, support rods 19 are provided at both ends of the heat transfer block 17, one end of the support rod 19 is fixed on the heat transfer block 17, a slide plate 20 is provided on the other end of the support rod 19, one side of the slide plate 20 is fixed on the support rod 19, a linear push rod 21 is provided in the middle of the other side of the slide plate 20, and the output end of the linear push rod 21 is fixed on the slide plate 20. By changing the distance between the heat transfer block 17 and the mounting cylinder 1, the heat transfer block 17 can perform thermal radiation heating on the mounting cylinder, that is, the reaction temperature can be controlled by controlling the distance between the two. It is not difficult to understand that the distance between the heat transfer block 17 and the mounting cylinder 1 can be controlled by electrically connecting the temperature sensor and the linear push rod 21.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
