Description

Technical Field

[0001] This invention belongs to the technical field of catalyst addition devices, and more specifically, relates to a catalyst addition device for a reaction vessel. Background Technology

[0002] In chemical production, operators often need to weigh a fixed amount of catalyst using tools such as electronic scales, and then add that amount of catalyst into the reactor. Since operators need to take out the catalyst and electronic scales to weigh it each time it is added, the work is quite cumbersome. Currently, there is a lack of a device on the market that can reduce the cumbersomeness of catalyst addition. Utility Model Content

[0003] The purpose of this invention is to provide a catalyst addition device for a reaction vessel, aiming to solve the problem that there is currently a lack of a device on the market that can reduce the cumbersomeness of catalyst addition work.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A catalyst adding device for a reaction vessel is provided, comprising a feed pipe, a distributing trough, a rotating shaft, multiple partition plates, and a driving assembly. The feed pipe is vertically arranged and is fixed to the vessel body of the reaction vessel and communicates with the vessel body. The distributing trough is fixed to the feed pipe with its opening facing upwards, and the bottom wall of the distributing trough has a discharge hole communicating with the feed pipe. The rotating shaft is vertically arranged and rotatably inserted into the bottom wall of the distributing trough, and the rotating shaft has a middle section located within the distributing trough. Multiple partition plates are located within the distributing trough, and the middle section is evenly distributed. One end of each partition plate is fixedly connected to the middle section, and the corresponding other end slides against the inner surface of the distributing trough. The multiple partition plates and the middle section divide the distributing trough into multiple distributing chambers. The driving assembly drives the rotating shaft to rotate, so that the multiple distributing chambers can sequentially communicate with the discharge hole.

[0005] In one possible implementation, the cross-section of the discharge hole, the cross-section of the internal space of the feed pipe, and the cross-section of the distribution chamber are all matched.

[0006] In one possible implementation, the rotating shaft further has a first connecting section located below the intermediate section, the diameter of the first connecting section being smaller than the diameter of the intermediate section, and the first connecting section being rotatably inserted into the bottom wall of the dispensing trough.

[0007] In one possible implementation, the catalyst addition device for the reactor further includes a cover plate. The cover plate is horizontally positioned, sleeved on the rotating shaft and covering the distribution trough. The cover plate has a feed hole, and rotation of the rotating shaft allows the plurality of distribution chambers to sequentially communicate with the feed hole.

[0008] In one possible implementation, the cover plate is fixedly connected to the material distribution trough, the middle section has a second connecting section located above the middle section, the diameter of the second connecting section is smaller than the diameter of the middle section, and the cover plate is sleeved over the second connecting section.

[0009] In one possible implementation, the drive assembly includes a drive motor and two meshing gears. The drive motor is fixed to the cover plate. The two meshing gears are respectively sleeved and fixed to the second connecting section and the output shaft of the drive motor.

[0010] In one possible implementation, the catalyst addition device for the reactor further includes a plugging member and a limiting strip. The plugging member is slidably inserted into the feed port. The limiting strip is fixed to the plugging member and abuts against the upper surface of the cover plate.

[0011] In one possible implementation, the catalyst adding device for the reactor further includes a connecting rod, a sliding shaft, and a compression spring. The connecting rod is located above the limiting strip and is used to connect to the cover plate. The sliding shaft is vertically arranged and slidably passes through one end of the connecting rod, and is fixed to the limiting strip. The compression spring is sleeved on the sliding shaft, and its two ends abut against the connecting rod and the limiting strip, respectively.

[0012] In one possible implementation, the catalyst adding device for the reactor further includes a fixed shaft. The fixed shaft is vertically arranged and fixed to the cover plate, and the other end of the connecting rod is rotatably sleeved on the fixed shaft. The side wall of the fixed shaft has two outwardly protruding limiting parts, which respectively abut against the upper and lower surfaces of the connecting rod.

[0013] In one possible implementation, the catalyst adding device for the reactor further includes a pull ring. The pull ring is fixed to the top end of the sliding shaft.

[0014] In this embodiment, when weighing the catalyst, except for the distribution chamber connected to the discharge port, a fixed amount of catalyst is placed in each of the remaining distribution chambers. Since the drive assembly drives the rotating shaft to rotate, multiple distribution chambers can sequentially connect to the discharge port. When a distribution chamber containing catalyst connects to the discharge port, the catalyst in that chamber can fall into the reactor body through the discharge port and the feed pipe. Therefore, by driving the rotating shaft to rotate, multiple additions of catalyst to the reactor body can be achieved. This eliminates the need for operators to weigh the catalyst and electronic scales each time it is added to the reactor, thus reducing the cumbersome nature of the work and addressing the current market lack of a device that reduces the complexity of catalyst addition.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0027] Please also refer to Figures 1 to 4 The catalyst adding device for a reactor provided by this utility model will now be described. The catalyst adding device for a reactor includes a feed pipe 1, a distribution trough 2, a rotating shaft 3, multiple partition plates 4, and a drive assembly 5. The feed pipe 1 is vertically arranged and is fixed to the reactor body 140 and communicates with the interior of the reactor body 140. The distribution trough 2 is fixed to the feed pipe 1 with its opening facing upwards, and the bottom wall of the distribution trough 2 has a discharge hole 21 communicating with the feed pipe 1. The rotating shaft 3 is vertically arranged and rotatably inserted into the bottom wall of the distribution trough 2. The rotating shaft 3 has a middle section 31 located within the distribution trough 2. Multiple partition plates 4 are located within the distribution trough 2, with the middle section 31 evenly distributed. One end of each partition plate 4 is fixedly connected to the middle section 31, and the corresponding other end slides against the inner surface of the distribution trough 2. The multiple partition plates 4 and the middle section 31 divide the distribution trough 2 into multiple distribution chambers 22. The drive assembly 5 is used to drive the rotating shaft 3 to rotate so that the multiple material distribution chambers 22 can be connected to the material discharge hole 21 in sequence.

[0028] The catalyst adding device for a reactor provided by this utility model, compared with the prior art, allows for the addition of a fixed amount of catalyst to each of the remaining distribution chambers 22, excluding the one connected to the discharge hole 21, during catalyst weighing. Since the drive assembly 5 drives the rotating shaft 3 to rotate, multiple distribution chambers 22 can sequentially connect to the discharge hole 21. When a distribution chamber 22 containing catalyst connects to the discharge hole 21, the catalyst in that chamber can fall into the reactor body 140 along the discharge hole 21 and the feed pipe 1. Therefore, by driving the rotating shaft 3 to rotate, the drive assembly 5 can add catalyst to the reactor body 140 multiple times. This eliminates the need for operators to weigh the catalyst and electronic scales each time it is added to the reactor body 140, thus reducing the complexity of the work and addressing the current market lack of a device that reduces the complexity of catalyst adding.

[0029] In this embodiment, the internal space of the material distribution trough 2, which is used to place the intermediate section 31 and multiple partition plates 4, has a cylindrical structure.

[0030] In some embodiments, see Figure 3 and Figure 4 The cross-sections of the discharge hole 21, the internal space of the feed pipe 1, and the distribution chamber 22 are all matched. Thus, when the distribution chamber 22 is aligned and connected with the discharge hole 21, the discharge hole 21, the internal space of the feed pipe 1, and the distribution chamber 22 combine to form a vertically arranged columnar channel, thereby allowing the catalyst in the distribution chamber 22 to fall completely into the reactor body 140.

[0031] In some embodiments, the aforementioned rotating shaft 3 can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The rotating shaft 3 also has a first connecting section 32 located below the middle section 31. The diameter of the first connecting section 32 is smaller than the diameter of the middle section 31. The first connecting section 32 is rotatably inserted into the bottom wall of the material distribution trough 2. The bottom wall of the material distribution trough 2 limits the middle section 31, which restricts the downward movement of the rotating shaft 3.

[0032] In some embodiments, see Figure 3 The catalyst adding device for the reactor also includes a cover plate 6. The cover plate 6 is horizontally positioned, fitted onto the rotating shaft 3, and covers the dispensing trough 2. The cover plate 6 has a feed hole 61. Rotation of the rotating shaft 3 allows multiple dispensing chambers 22 to sequentially connect to the feed hole 61. When catalyst needs to be weighed, two adjacent dispensing chambers 22 are connected to the feed hole 61 and the discharge hole 21, respectively. A measured amount of catalyst is added to the dispensing chamber 22 connected to it through the feed hole 61. Then, the driving assembly 5 drives the rotating shaft 3 to rotate, causing the dispensing chamber 22 connected to the discharge hole 21 to rotate to the position connected to the feed hole 61. Catalyst is then added to this dispensing chamber 22, and so on.

[0033] In some embodiments, see Figure 2 and Figure 3 The cover plate 6 is fixedly connected to the material distribution trough 2. The middle section 31 has a second connecting section 33 located above the middle section 31. The diameter of the second connecting section 33 is smaller than the diameter of the middle section 31. The cover plate 6 is sleeved on the outside of the second connecting section 33. The upward movement of the rotating shaft 3 can be restricted by limiting the middle section 31 by the cover plate 6.

[0034] In some embodiments, the feature-driving component 5 described above may employ, for example... Figure 2 The structure shown. See also Figure 2 The drive assembly 5 includes a drive motor 51 and two meshing gears 52. The drive motor 51 is fixed to the cover plate 6. The two meshing gears 52 are respectively sleeved and fixed on the second connecting section 33 and the output shaft of the drive motor 51. The output shaft of the drive motor 51 drives the rotating shaft 3 to rotate through the two meshing gears 52.

[0035] In some embodiments, see Figure 2 The catalyst addition device for the reactor also includes a sealing element 7 and a limiting strip 8. The sealing element 7 is slidably inserted into the feed hole 61. The limiting strip 8 is fixed to the sealing element 7 and fits against the upper surface of the cover plate 6, thereby restricting the downward sliding of the sealing element 7. The sealing element 7 blocks the feed hole 61, thus allowing the sealing element 7 and the cover plate 6 to cover all the dispensing chambers 22, thereby protecting the catalyst in the dispensing chambers 22. When it is necessary to add catalyst into the dispensing chambers 22, the sealing element 7 is driven to slide upward and exit the feed hole 61.

[0036] In some embodiments, see Figure 2 The catalyst addition device for the reactor also includes a connecting rod 9, a sliding shaft 10, and a compression spring 110. The connecting rod 9 is located above the limiting strip 8 and is used to connect to the cover plate 6. The sliding shaft 10 is vertically arranged and slides through one end of the connecting rod 9, and is fixed to the limiting strip 8. The compression spring 110 is sleeved on the sliding shaft 10, with its two ends abutting against the connecting rod 9 and the limiting strip 8, respectively. Because the connecting rod 9 is connected to the cover plate 6, the rebound force of the compression spring 110 increases the resistance to the upward sliding of the sealing member 7, thereby increasing the reliability of the sealing member 7 in sealing the feed hole 61.

[0037] In some embodiments, see Figure 2 and Figure 5 The catalyst adding device for the reactor also includes a fixed shaft 120. The fixed shaft 120 is vertically arranged and fixed to the cover plate 6. The other end of the connecting rod 9 is rotatably sleeved on the fixed shaft 120. The side wall of the fixed shaft 120 has two outwardly protruding limiting parts 1201, which are respectively attached to the upper and lower surfaces of the connecting rod 9, thereby restricting the movement of the connecting rod 9 in the vertical direction, so that the connecting rod 9 is rotatably connected to the cover plate 6 through the fixed shaft 120. When the sealing member 7 slides upward and exits the feed hole 61, the rotation of the connecting rod 9 causes the sealing member 7 to reach one side of the feed hole 61, thereby facilitating the addition of catalyst into the dispensing chamber 22 through the feed hole 61.

[0038] In some embodiments, see Figure 2 The catalyst addition device for the reactor also includes a pull ring 130. The pull ring 130 is fixed to the top of the sliding shaft 10. By pulling the sliding shaft 10 upward through the pull ring 130, the sealing member 7 slides upward and exits the feed hole 61.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
