Description

Technical Field

[0001] This invention relates to the field of cyclosulfonone preparation technology, and more specifically to an apparatus for preparing cyclosulfonone technical. Background Technology

[0002] Tembotrione is a highly effective triketone herbicide, mainly used in cornfields to control broadleaf weeds and some grass weeds. Its production process involves multiple organic synthesis reactions, the core of which lies in constructing the benzoxazinone ring, sulfonyl group, and key substituent groups in the molecule.

[0003] The main starting materials for cyclosulfonones include: o-methoxy / chlorobenzoyl chloride derivatives (such as 3-chloro-2-methylbenzoyl chloride): used to construct the benzoyl group structure; p-aminobenzenesulfonamide compounds (such as N-acetyl-p-aminobenzenesulfonamide): providing sulfonamide groups and amino active sites; other reagents: such as strong acids (hydrochloric acid, sulfuric acid), bases (sodium hydroxide, potassium carbonate), solvents (dichloromethane, DMF, toluene), catalysts (such as triethylamine, potassium iodide), etc. The core structure of cyclosulfonones is the benzoxazinone ring (formed by the fusion of a benzene ring and an oxazinone ring). Its synthesis usually involves the following steps: acylation reaction: 3-chloro-2-methylbenzoyl chloride and p-aminobenzenesulfonamide are condensed under alkaline conditions (such as potassium carbonate) to generate N-(4-sulfonamidophenyl)-3-chloro-2-methylbenzamide; cyclization reaction: The above amide intermediate is heated under acidic conditions (such as hydrochloric acid) to undergo intramolecular dehydration cyclization, forming the benzoxazinone ring structure (i.e., key intermediate A).

[0004] In the chemical preparation of active pharmaceutical ingredients, reaction vessels are crucial chemical equipment. Patent CN119565554A discloses a reaction vessel belonging to the field of pharmaceutical technology. It includes a reaction vessel with a lid movably mounted on top. A first motor is mounted at the center of the lid's top. A stirring assembly, fixedly connected to the drive shaft of the first motor, is located below the lid. Several sets of stirring rods are fixedly connected to both sides of the stirring assembly. A sealing assembly is provided at the connection between the lid and the reaction vessel. A mounting frame is located on the outer periphery of the reaction vessel near its bottom. A rotating assembly is located at the connection between the reaction vessel and the mounting frame. This invention not only seals the connection between the reaction vessel and the lid during the reaction process, effectively preventing heat leakage from affecting the reaction effect, but also allows for more thorough mixing of the raw materials through the different counter-rotation of the stirring rods and the reaction vessel body, effectively improving the reaction rate. The above technical solution has the following technical problems: When raw materials are prepared in the reaction vessel, different raw materials are added to the inside of the reaction vessel and then mixed evenly by stirring so that the different raw materials can fully react. However, in industrial production, the reaction vessel is relatively large. When a large amount of raw materials are added at one time and mixed together, it is inconvenient to mix them fully, and different chemical agents cannot react fully. Summary of the Invention

The inner diameter of the feed pipe is equal to the inner diameter of the through pipe.

[0012] An adjusting disc is slidably inserted into the trough. A threaded rod is installed on the upper end of the adjusting disc.

[0020] In summary, the present invention has the following beneficial effects: 1. This invention, by setting up components such as a secondary mixing chamber group and a secondary mixing mechanism, allows the material transfer mechanism to add raw materials into the secondary mixing chamber group while rotating. The active coupling drives the secondary mixing mechanism to first pre-mix the raw materials in the secondary mixing chamber group. The pre-mixed raw materials are discharged from the bottom and then mixed as a whole, ensuring the efficiency of mixing and allowing the various chemical agents to react fully.

[0021] 2. This invention, by setting up components such as a movable base, a mixing sub-cylinder, a ring frame, and a mixing ring, ensures that the ring frame and movable base cannot rotate within the constraints of the mixing sub-cylinder. As the reciprocating screw drum rotates, the ring frame gradually drives the mixing ring and mixing plate downwards. The reciprocating screw drum, through a vertical rod, drives the mixing ring and mixing plate to rotate and stir the raw materials inside the mixing sub-cylinder. Simultaneously, as the mixing plate rotates downwards, it continuously mixes the raw materials at different heights within the mixing sub-cylinder. After the mixing ring contacts the movable base, it continues to move downwards, causing the movable base to gradually move downwards, allowing the gap in the mixing sub-cylinder to leak out from the upper side of the movable base. The raw materials, after preliminary stirring, can be discharged from the gap in the mixing sub-cylinder.

[0022] 3. This invention, by setting up components such as a ring column, a material trough, and an adjusting material tray, allows the rotating threaded rod to mesh with the ring column, controlling the height of the adjusting material tray within the material trough. When the ring column drives the material trough to connect with the feeding pipe, multiple feeding pipes can add raw materials to different material troughs. Simultaneously, the amount of material added at one time is controlled according to the height of the adjusting material tray. Then, when the ring column drives the material trough to connect with the feeding pipe, the raw materials in the material trough can be added to the mixing auxiliary cylinder in a certain proportion, with the raw materials added in proportion each time.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: The following is in conjunction with the appendix Figure 1-10 The present invention will be described in further detail below.

[0029] A secondary stirring chamber assembly 4 is installed at the upper part of the reactor body 1. The secondary stirring chamber assembly 4 includes a secondary stirring cylinder 41 and a movable base 42. The movable base 42 is slidably inserted into the secondary stirring cylinder 41. The inner ring surface of the secondary stirring cylinder 41 is multi-faceted. The outer ring surface of the movable base 42 is adapted to the inner ring surface of the secondary stirring cylinder 41. The movable base 42 can only move vertically within the secondary stirring cylinder 41. The secondary stirring cylinder 41 is installed at the upper part of the reactor body 1. The lower end of the secondary stirring chamber assembly 4 can be opened to discharge materials downwards. 2. The bottom surface is elastically connected to the lower end of the stirring auxiliary cylinder 41. The elastic connection is preferably a spring. The lower end of the stirring auxiliary cylinder 41 is located on the lower side of the movable base 42 with a notch. The movable base 42 is located on the upper side of the notch of the stirring auxiliary cylinder 41 under the elastic connection with the stirring auxiliary cylinder 41, so that the raw material is inside the stirring auxiliary cylinder 41. When the movable base 42 is subjected to pressure and moves downward, the notch leaks out from the upper side of the movable base 42. The mixed raw material is discharged from the notch at the lower end of the stirring auxiliary cylinder 41 into the raw material on the lower side of the reactor body 1 for mixing.

[0030] The active coupling 2 is installed through the axis of the auxiliary mixing chamber group 4. The main mixing mechanism 3 is located on the lower side of the auxiliary mixing chamber group 4. The main mixing mechanism 3 includes multiple main mixing frames 31. The main mixing frames 31 are fixed to the active coupling 2. The multiple main mixing frames 31 are spirally distributed inside the reactor body 1. The active coupling 2 drives the main mixing frames 31 to mix the raw materials in the reactor body 1. The spirally distributed main mixing frames 31 can mix the raw materials in different directions at the same time.

[0031] A secondary mixing mechanism 5 is provided inside the secondary mixing chamber 4. The secondary mixing mechanism 5 is fixed coaxially with the active coupling shaft 2, and the lower end of the active coupling shaft 2 is installed coaxially with the main mixing mechanism 3.

[0032] The auxiliary stirring mechanism 5 is located on the upper side of the movable base 42 inside the auxiliary stirring cylinder 41.

[0033] The auxiliary stirring mechanism 5 includes a reciprocating screw 51 and a ring frame 52. The reciprocating screw 51 is rotatably sleeved on the outer surface of the drive shaft 2. The lower end of the reciprocating screw 51 is rotatably connected to the lower end of the stirring auxiliary cylinder 41. The ring frame 52 is slidably inserted into the inner side of the stirring auxiliary cylinder 41. The ring frame 52 can only move up and down relative to the stirring auxiliary cylinder 41. The ring frame 52 is threadedly sleeved on the outer surface of the reciprocating screw 51.

[0034] A stirring ring 53 is rotatably sleeved at the upper axis of the ring frame 52. Multiple stirring plates 55 are fixed on the outer ring surface of the stirring ring 53. A vertical rod 54 is fixed on the upper surface of the stirring ring 53. The upper end of the reciprocating screw spool 51 is slidably sleeved on the outer surface of the vertical rod 54. The stirring ring 53 rotates synchronously with the reciprocating screw spool 51 through the vertical rod 54. A circular groove 56 is opened on the inner side of the upper end of the reciprocating screw spool 51. A rib groove 57 is opened on the bottom wall of the circular groove 56. A cylinder 58 is slidably inserted into the inner side of the circular groove 56. An outer rib sleeve 510 is fixed on the bottom surface of the cylinder 58. The outer ring surface of the outer rib sleeve 510 is adapted to the rib groove 57.

[0035] As the cylinder 58 moves downwards, causing the outer rib sleeve 510 to insert into the rib groove 57, it drives the reciprocating screw drum 51 to rotate. The stirring plate 55, through the stirring ring 53 and the upright rod 54, follows the rotation of the reciprocating screw drum 51 to mix the raw materials in the mixing auxiliary cylinder 41. The stirring plate 55 is initially at the top, and during its rotation, it collides with the flowing raw materials, causing them to disperse and fall. Simultaneously, the ring frame 52 engages with the rotating reciprocating screw drum 51. The ring frame 52 first moves downwards, causing the stirring plate 55 to follow the rotation of the ring frame 51. The frame 52 moves downward to mix and stir the raw materials at different heights in the mixing sub-cylinder 41. When the stirring ring 53 moves downward to apply a pushing force to the movable base 42, the movable base 42 gradually moves downward, allowing the mixed raw materials on the upper side of the movable base 42 to be discharged. After the raw materials are discharged, the reciprocating screw drum 51 continues to rotate, and the ring frame 52 engages with the reciprocating screw drum 51 and moves upward again to reset, causing the movable base 42 to move upward again to seal the lower end of the mixing sub-cylinder 41, making it easier for the raw materials to be added to the mixing sub-cylinder 41 again for mixing.

[0036] A transmission mechanism 59 is slidably inserted at the axis of the active coupling 2. The lower end of the transmission mechanism 59 slides through the inner wall of the active coupling 2 and is fixed to the inner wall of the cylinder 58. The transmission mechanism 59 controls the cylinder 58 to move up and down.

[0037] The apparatus for preparing cyclosulfonone technical material in this embodiment further includes: a material transfer mechanism 6, on the bottom surface of which is installed an equal number of feed pipes 7 and feed tubes 8. Raw materials are added from the feed pipes 7. The feed pipes 7 and feed tubes 8 are distributed alternately at equal arc angles around the circumference. The other end of the feed tube 8 passes through the upper end of the reactor body 1. One end of the feed tube 8 located inside the reactor body 1 is connected to the auxiliary stirring chamber group 4. The material transfer mechanism 6 can rotate alternately and is connected to the feed pipes 7 and feed tubes 8. When the material transfer mechanism 6 is connected to the feed tubes 8, the raw materials in the material transfer mechanism 6 can be added to the auxiliary stirring chamber 41.

[0038] A material-aggregating cylinder 43 is coaxially arranged on the upper side of the stirring auxiliary cylinder 41. The upper end of the material-aggregating cylinder 43 is conical and recessed, and the center of the cone of the material-aggregating cylinder 43 is circularly open. The material-aggregating cylinder 43 is coaxially fixed inside the reactor body 1. The material-aggregating cylinder 43 aggregates the raw materials added into the reactor body 1, ensuring that the added raw materials flow into the inside of the material-aggregating cylinder 43.

[0039] The material transfer mechanism 6 includes a fixed outer cylinder 61 and an annular column 62. The annular column 62 is rotatably inserted into the inner side of the fixed outer cylinder 61. The fixed outer cylinder 61 is fixedly installed on the upper end of the reactor body 1. Multiple material troughs 63 are opened on the bottom surface of the annular column 62. The number of material troughs 63 is equal to the number of feed pipes 7. The width between two adjacent material troughs 63 is greater than the inner diameter of the feed pipe 7. During the rotation of the annular column 62, the material troughs 63 will not be connected to the feed pipe 7 and the through pipe 8 at the same time. The inner diameter of the feed pipe 7 is equal to the inner diameter of the through pipe 8.

[0040] The transmission mechanism 59 includes a transmission shaft 591. Both the upper and lower ends of the transmission shaft 591 slide through the inner wall of the drive coupling 2. The drive coupling 2 is in the form of a vertical groove at both the upper and lower ends of the transmission shaft 591. The lower end of the transmission shaft 591 is located on the outer side of the drive coupling 2 and is fixed to the cylinder 58.

[0041] The upper end of the drive shaft 591 is fixed with a sleeve 592 outside the active coupling 2. An angle plate 593 is rotatably sleeved on the outer surface of the sleeve 592. An elastic telescopic rod 594 is installed through the upper end of the angle plate 593. The lower end of the elastic telescopic rod 594 is fixed to the reactor body 1. The elastic telescopic rod 594 has the tendency to push the angle plate 593 upward, so that the outer rib sleeve 510 is disengaged from the rib groove 57. The active coupling 2 will not drive the reciprocating screw 51 to rotate during rotation. When there is no raw material in the stirring auxiliary cylinder 41, the ring frame 52 and the stirring plate 55 will not rotate, reducing the power consumption when the active coupling 2 rotates. An annular bending plate 595 is contacted at the upper end of the elastic telescopic rod 594. The annular bending plate 595 is fixed to the upper end of the ring column 62.

[0042] The annular bending plate 595 is coaxial with the active coupling 2. The two ends of the annular bending plate 595 are annular plate structures with different heights. The middle position of the annular bending plate 595 is inclined. When the material trough 63 is connected to the feeding pipe 7, the elastic telescopic rod 594 contacts the highest point of the annular bending plate 595, causing the outer rib sleeve 510 to disengage from the rib groove 57. When the material trough 63 is connected to the feeding pipe 8, the upper end of the elastic telescopic rod 594 is located at the lowest point of the annular bending plate 595. Through the transmission shaft 591, the outer rib sleeve 510 and the rib groove 57 are engaged, causing the reciprocating screw drum 51 to rotate.

[0043] An adjusting material tray 64 is slidably inserted into the material trough 63. A threaded rod 66 is installed on the upper end of the adjusting material tray 64. The threaded rod 66 passes through the inner top wall of the material trough 63. A power mechanism 65 for controlling the swing of the ring column 62 is installed on the outside of the fixed outer cylinder 61. Rotating the threaded rod 66 engages with the ring column 62, controlling the height of the adjusting material tray 64 in the material trough 63, controlling the amount of raw material that the feeding pipe 7 can fill into the material trough 63, and controlling the proportion of raw material added so that the raw material added each time is added into the mixing auxiliary cylinder 41 in the same proportion.

[0044] The power mechanism 65 includes a gear ring plate 651, which is coaxially mounted on the upper surface of the ring column 62. A motor 652 is fixed on the outer ring surface of the fixed outer cylinder 61. A drive gear 653 meshes with the outer ring surface of the gear ring plate 651. The drive gear 653 is elastically rotated and sleeved on the output end of the motor 652.

[0045] The upper end face of the toothed ring plate 651 is provided with an arc groove 654 that runs vertically through it. A positioning post 655 is slidably inserted into the arc groove 654. The positioning post 655 is fixed to the fixed outer cylinder 61. The range of motion of the positioning post 655 in the arc groove 654 is equal to the angle between the axes of the adjacent feed pipe 7 and the feed pipe 8. When the drive gear 653 rotates and meshes with the toothed ring plate 651, the positioning post 655 moves in the arc groove 654. When the positioning post 655 is located at both ends of the arc groove 654, the material trough 63 is connected to the feed pipe 7 and the feed pipe 8 respectively. When the motor 652 controls the drive gear 653 to rotate forward and backward, it drives the ring post 62 to rotate forward and backward.
