Description

Technical Field

[0001] The invention relates to the technical field of synthesis devices, and more specifically to a synthesis device for prothioconazole chlorination reaction. Background Art

[0002] Prothioconazole is a broad-spectrum plant protection agent, belonging to the triazole fungicide. It is mainly used to prevent and treat fungal diseases on a variety of crops, such as wheat, corn, beans, etc. Prothioconazole has low toxicity, no teratogenicity, no mutagenicity, no toxicity to embryos, and is safe for humans and the environment. In order to improve the photochemical and thermal stability of the compound, prothioconazole needs to be chlorinated. By changing the polarity of its molecules, the absorption and distribution of the agent in the plant can be improved.

[0003] In the prior art, the chlorination reaction synthesis of prothioconazole is generally carried out by using a reactor and other devices. First, ensure that all systems of the device are operating normally, add the prepared raw materials into the reactor, and then start the stirring system. During the stirring process, the raw materials inside are heated to a specific temperature (the reaction temperature of prothioconazole is generally room temperature or above room temperature), and then the reaction reagent is added. During the reaction, the flow rate needs to be controlled to avoid a violent reaction. The cooling system is used to prevent the reaction from overheating, so that the inside of the reactor is always kept within the ideal temperature range of the reaction. After the reaction is completed, separation is performed to obtain the final product. However, due to the special shape and structure of the reactor, the raw materials will be unevenly mixed when stirred inside, resulting in uneven distribution of the reactants and reduced reaction efficiency. At the same time, uneven stirring will cause excessive accumulation of raw materials, and the raw materials at the bottom of the reactor cannot be turned over, resulting in the bottom temperature being higher than the top temperature. At this time, the reactants react quickly in the high temperature zone and slowly in the low temperature zone, which leads to the problem of low overall reaction efficiency of the reactants.

[0004] In view of the above situation, the present invention designs a synthesis device for prothioconazole chlorination reaction to solve the above technical problems. Summary of the invention

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0020] refer to Figure 1 , Figure 2 , Figure 3A synthesis device for chlorination reaction of prothioconazole, used for controlling the continuous and uniform chlorination reaction of prothioconazole, comprises a device body 1, a shell 11 is arranged on the device body 1, and a device base 111 is arranged at the bottom of the shell 11, and the device base 111 is used to control the stability of the whole device, an outer cylinder 12 is coaxially arranged inside the shell 11, a driving member 121 is coaxially arranged on the top of the outer cylinder 12, and a feeding pipe 122 is arranged on one side of the driving member 121, the feeding pipe 122 passes through the outer cylinder 12, a discharge pipe 123 is arranged at the bottom of the outer cylinder 12, a storage cylinder 13 is coaxially arranged inside the outer cylinder 12, and the storage cylinder 13 is fixed to the bottom of the outer cylinder 12 through a support frame 131 at the bottom, and a fixed The output end of the driving member 121 is connected to a driving shaft 2, and the end of the driving shaft 2 away from the driving member 121 is connected to a driving mechanism 3, and a flow control component 4 is arranged on one side of the driving mechanism 3, and the flow control component 4 extends into the interior of the storage barrel 13, and the flow control component 4 is close to the bottom of the storage barrel 13, and the flow control component 4 is fixed by a fixing frame 132; the end of the driving mechanism 3 away from the driving shaft 2 is connected to a drainage component 5, and the driving mechanism 3 is in contact with the flow control component 4, and the driving shaft 2 drives the driving mechanism 3 to move synchronously, and the driving mechanism 3 controls the flow direction of the raw materials inside the storage barrel 13 through the drainage component 5, and the driving mechanism 3 drives the flow control component 4 to move when the driving mechanism 3 moves, and the flow control component 4 rotates so that the raw materials inside the storage barrel 13 are fully chlorinated.

[0021] During the working process, the operator first ensures that the entire device can operate normally, and then the operator adds the reactants into the storage barrel 13 through the feed pipe 122 on the top of the outer barrel 12. During the reaction, the outer shell 11 can keep the entire device warm to avoid temperature differences inside the device. A stop valve is provided in the discharge pipe 123. The stop valve is closed before the reaction starts. After the reactants are added, the operator starts the driving member 121. The rotation of the driving member 121 drives the driving shaft 2 to rotate. The rotation of the driving shaft 2 drives the driving mechanism 3 to rotate. The rotation of the driving mechanism 3 drives the flow control component 4 to rotate. At this time, the reactants inside the storage barrel 13 can be evenly distributed in the storage barrel 13 through the rotation of the flow control component 4. At this time, the operator adds the reaction reagents through the feed pipe 122. When adding reaction reagents, the flow control component 4 can repeatedly stir the reactants by driving the flow control part 44. The stirring of the flow control part 44 can make the reactants and the reaction reagents fully react, thereby ensuring the reaction efficiency of the entire device and preventing the reactants in the corners of the storage tube 13 from being unable to react with the reaction reagents. The driving mechanism 3 is driven to move by the driving shaft 2. The driving mechanism 3 mobilizes the drainage part 5 to allow the reactants inside the storage tube 13 to circulate between the storage tube 13 and the outer tube 12. The reactants circulate between the storage tube 13 and the outer tube 12, so that the temperature of the top and bottom of the reactants is uniform, avoiding large temperature differences inside the reactants, thereby avoiding different reaction rates at the top and bottom, resulting in over-reaction or non-reaction of the reactants, and thus avoiding the overall reaction efficiency being affected.

[0022] The driving member 121 includes a driving motor, the output end of which vertically penetrates the housing 11 and is connected to the driving shaft 2, and the driving motor directly drives the driving shaft 2 to rotate. The vertically arranged driving motor can avoid shaking during movement, and the driving motor directly drives the driving shaft 2 to rotate. During the movement, the energy loss in the transmission system is reduced, and the overall energy efficiency can be improved. In addition, direct drive can achieve precise speed control.

[0023] The driving mechanism 3 includes a fixed block 31, a driving shaft 32 and a driving gear 33. The fixed block 31 is arranged at the bottom end of the driving shaft 2, and a small pulley 311 is arranged above the fixed block 31. A large pulley 313 is arranged on one side of the small pulley 311. The small pulley 311 and the large pulley 313 are connected by a transmission belt 312. The large pulley 313 is coaxially provided with the driving shaft 32, and the driving gear 33 is connected to the side of the driving shaft 32 away from the large pulley 313.

[0024] During the working process, the driving shaft 2 rotates. At this time, the small pulley 311 arranged above the fixed block 31 can transmit the rotation of the small pulley 311 to the large pulley 313 through the transmission belt 312 connected between the small pulley 311 and the large pulley 313. Since the large pulley 313 is coaxially provided with a driving shaft 32, the large pulley 313 drives the driving shaft 32 to move synchronously. When the driving shaft 32 rotates, it drives the coaxially arranged driving gear 33 to rotate. Through such a setting, during the reaction process, the rotation of the driving gear 33 can drive the flow control component 4 to stir the reactants inside the storage barrel 13, thereby ensuring that the reactants inside the storage barrel 13 fully react while making the reactants evenly distributed at the bottom of the storage barrel 13.

[0025] The fixed block 31 is divided into two parts, one part of the fixed block 31 is fixedly connected to the driving shaft 2, and the other part of the fixed block 31 is rotatably connected to the flow control component 4, and the part of the fixed block 31 connected to the flow control component 4 is tilted to the part of the fixed block 31 connected to the driving shaft 2. Through such a setting, since one part of the fixed block 31 is tilted to the other part, and the other part is connected with the driven shaft 41 in the control component, the driven shaft 41 is rotatably connected to the fixed block 31. When the driving shaft 2 drives the driven shaft 41 to rotate through the fixed block 31, the driven shaft 41 performs an eccentric motion at one end connected to the fixed block 31, and the other end of the driven shaft 41 performs the same eccentric motion, so that the flow control component 4 can stir the reactants in a larger range, thereby avoiding the accumulation of reactants.

[0026] refer to Figure 4 , Figure 5 The flow control component 4 includes a driven shaft 41, a control block 42, a driven gear 43 and a flow control member 44. The driven shaft 41 is coaxially arranged with the fixed block 31, and the driven shaft 41 is arranged through the fixed frame 132. A driven gear 43 is arranged in the middle part of the driven shaft 41, and the driven gear 43 is meshed with the driving gear 33. The driven gear 43 is respectively provided with control blocks 42 above and below, and the control block 42 is rotatably arranged with the fixed frame 132. The other end of the driven shaft 41 away from the fixed block 31 is connected to the flow control member 44, and the flow control member 44 is used to control the flow direction of the raw materials inside the storage tube 13.

[0027] During operation, the control block 42 arranged in the middle of the driven shaft 41 is in the middle position of the fixed frame 132, and the shape of the control block 42 is semi-elliptical, and the contact position between the control block 42 and the fixed frame 132 is ball contact. When the driving gear 33 drives the driven gear 43 to rotate, the driven gear 43 can drive the control block 42 arranged in the middle of the driven shaft 41 to reciprocate on the fixed frame 132, and because the driven shaft 41 and the fixed block 31 are rotatably connected, when the driven gear 43 rotates, it can drive the driven shaft 41 to rotate on the fixed block 31, and the rotation of the driven shaft 41 can drive the flow control member 44 to rotate synchronously, so that the flow direction of the reactant inside the storage cylinder 13 is controlled by the flow control member 44.

[0028] The flow control component 44 includes a support block 441, a support plate 443, a support column 444 and a spiral blade 445. The support block 441 is connected to one end of the driven shaft 41. A plurality of support plates 443 are arranged in an array on the circumferential surface of the support block 441, and a support column 444 is arranged below the support plate 443. The circumferential surface of the support column 444 is provided with a spiral blade 445, and the spiral blade 445 is rotatably arranged on the circumferential surface of the support column 444.

[0029] During the operation, the driven shaft 41 rotates, and the driven shaft 41 drives the support block 441 to rotate. The rotation of the support block 441 can drive the support plate 443 and the support column 444 on its circumferential surface to stir the reactants inside the storage barrel 13. When the reactants are stirred and flowed by the support column 444, the reactants can push the spiral blade 445 to rotate. The rotation of the spiral blade 445 can repeatedly flip the reactants, thereby ensuring that the reactants inside the storage barrel 13 are fully reacted.

[0030] The circumferential surface array of the support block 441 is provided with a plurality of flow control plates 442, and the flow control plates 442 are arc-shaped and rotatably arranged on the circumferential surface of the support block 441. Through such an arrangement, the arc-shaped flow control plates 442 can make the reactants inside the storage barrel 13 slide along the surface of the flow control plates 442. At this time, the reactants flow upward along the flow control plates 442, and then flow downward along the flow control plates 442, so that the reactants at the bottom of the storage barrel 13 fall repeatedly, thereby avoiding the reactants inside the storage barrel 13 from having an excessively high temperature, thereby avoiding the problem of low or excessive reaction efficiency of the reactants.

[0031] The drainage member 5 includes a sealing ring 51, a drainage hole 52 and a gear ring 53. The sealing ring 51 is coaxially arranged with the storage tube 13. A plurality of circulation holes 133 are arranged on the circumferential surface of the storage tube 13, and a plurality of drainage holes 52 are arranged in an annular manner on the circumferential surface of the sealing ring 51. A gear ring 53 is arranged above the sealing ring 51. The gear ring 53 is meshed with the driving gear 33. The driving gear 33 rotates to drive the sealing ring 51 to rotate. The sealing ring 51 rotates so that the drainage hole 52 coincides with the circulation hole 133.

[0032] During operation, the driving gear 33 meshes with the gear ring 53 on the sealing ring 51. When the driving gear 33 rotates, the sealing ring 51 is driven to rotate. At this time, the drainage hole 52 on the sealing ring 51 coincides with the circulation hole 133 on the circumferential surface of the storage cylinder 13. When the drainage hole 52 coincides with the circulation hole 133, the reactant will flow into the interlayer between the storage cylinder 13 and the outer cylinder 12. When the drainage hole 52 does not coincide with the circulation hole 133, the reactant will remain inside the storage cylinder 13, thereby realizing the periodic circulation of the reactant and ensuring the uniform temperature inside the reactant.

[0033] The drainage hole 52 is a conical structure with a large inlet and a small outlet, and the circulation hole 133 is a conical structure with a small inlet and a large outlet. Through such an arrangement, when the reactants flow from the drainage hole 52 to the circulation hole 133, the flow path gradually becomes smaller, reducing the risk of reactant accumulation and blockage. When the reactants flow out of the circulation hole 133, the smaller outlet limits the flow rate, allowing the reactants to flow in an orderly manner.

[0034] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
