Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide production equipment technology, specifically to a multi-stage tubular reaction device for pesticide production. Background Technology
[0002] In the production of pesticides, it is usually necessary to mix and react multiple compounds. During the pesticide production process, a reaction device is used to react the required compound materials according to the reaction steps. Currently, the reaction devices used in agricultural production usually include batch reactors, tubular reactors, etc.
[0003] In actual pesticide production using the aforementioned tubular reactor, it was found that due to the continuous flow and reaction of materials in the long tube of the reactor, the inner side of the long tube is prone to blockage over time. These blocked materials are unstable and can easily affect the normal flow and reaction of materials. At the same time, there are sudden flow separations during the pesticide production reaction, which affect the ratio of the mixed materials and are not conducive to ensuring the quality of the pesticide production reaction.
[0004] In summary, there is a need for a tubular reaction apparatus that facilitates the stable reaction of compounds. Utility Model Content

[0008] The reaction assembly includes a reaction tube, a first reflux tube, and a second reflux tube. The first reflux tube is distributed in opposite directions, and its two ends are connected to the ends of the first reflux tube and the second reflux tube, respectively. The reaction mechanism includes a crossbar and baffles. The crossbar is arranged correspondingly to the reaction tube, and baffles are provided on the outside of the crossbar. Multiple sets of baffles are provided at equal intervals on the inside of the reaction tube.
[0009] Furthermore, the reaction mechanism also includes an electric push rod, a mounting plate, and a second motor. The electric push rod is located on the side of the return pipe, and the end of the electric push rod is provided with a mounting plate. The second motor is located in the middle of the side of the mounting plate away from the electric push rod. The output end of the second motor is connected to the crossbar. The edge of the baffle plate is in close contact with the inside of the reaction pipe, and the baffle plate is engaged and slides with the reaction pipe.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] To address the technical problems in the background section, the following multi-stage tubular reaction apparatus for pesticide production is provided:
[0024] Combination Figures 1-4 As shown, this utility model provides a multi-stage tubular reaction device for pesticide production, including a reaction chamber 1. Multiple reaction components 2 containing reactants are arranged inside the reaction chamber 1. A mixing component 3 for mixing the reactants is located at one end of each reaction component 2. A reaction mechanism 4 for mixing the reactants is located at the end of the reaction component 2 opposite to the mixing component 3. A temperature control component 5 for stabilizing the reaction is located outside the reaction component 2. The reaction component 2 includes a reaction tube 21, a first reflux tube 22, and a second reflux tube 23. The first reflux tube 22 is relatively distributed, and the reflux... The two ends of the first tube 22 are connected to the ends of the first return tube 22 and the second return tube 23, respectively. The arrangement of the reaction tube 21, the first return tube 22 and the second return tube 23 enables the material to flow and mix during the reaction. The reaction mechanism 4 includes a crossbar 41 and a baffle 42. The crossbar 41 is correspondingly arranged with the reaction tube 21. The baffle 42 is provided on the outside of the crossbar 41. Multiple sets of baffles 42 are equally spaced on the inside of the reaction tube 21. The multiple sets of baffles 42 can turbulent and cut the material during the material flow reaction, thereby improving the uniformity of material mixing.
[0025] As an improvement to the above scheme, the reaction mechanism 4 also includes an electric push rod 43, a mounting plate 44, and a second motor 45. The electric push rod 43 is located on the side of the second return pipe 23. The electric push rod 43 can move the crossbar 41 and the baffle 42 repeatedly in the reaction pipe 21. The end of the electric push rod 43 is provided with a mounting plate 44. The second motor 45 is located in the middle of the side of the mounting plate 44 away from the electric push rod 43. The output end of the second motor 45 is connected to the crossbar 41. The edge of the baffle 42 is in close contact with the inner side of the reaction pipe 21. The baffle 42 engages and slides with the reaction pipe 21. The baffle plate 42, which is attached to the reaction tube 21, can move inside the reaction tube 21. While cutting the baffle material, it keeps the material flow in the reaction tube 21 smoothly and prevents the material from settling and blocking in the reaction tube 21. At the same time, the motor 45 drives the baffle plate 42 to rotate. At this time, the baffle plate 42 can push the material during the cutting of the baffle material, further reducing the possibility of material settling and blocking. This is conducive to the stable flow reaction of the material in the reaction component 2 and maintains the mixing reaction effect of the material.
[0026] In this embodiment, the temperature control component 5 includes a temperature control sleeve 51 and a liquid guide tube 52. The temperature control sleeve 51 is correspondingly arranged with the reaction tube 21 and is located outside the reaction tube 21. The end of the liquid guide tube 52 is connected to the temperature control sleeve 51, and the end of the liquid guide tube 52 away from the temperature control sleeve 51 extends to the outside of the reaction chamber 1. The liquid guide tube 52 can send media of different temperatures into the temperature control sleeve 51 to adjust the reaction environment in the reaction tubes 21 at different levels, which is beneficial to adapting to the reaction conditions of different steps of pesticides.
[0027] In this embodiment, a feed pipe 11 is provided at the top of the reaction chamber 1, and the bottom end of the feed pipe 11 is connected to the first return pipe 22. Multiple feeding pipes 12 are provided on the side of the reaction chamber 1, and the feeding pipes 12 are correspondingly arranged with the first return pipe 22. The feeding pipes 12 are used to deliver the additives required for different steps of the pesticide reaction into the reaction components 2 at different levels. A discharge pipe 24 is provided at the bottom of the second return pipe 23, and a discharge valve 25 for controlling the flow of materials is provided in the middle of the discharge pipe 24. The discharge pipe 24 is connected to the interior of the second return pipe 23 below.
[0028] To ensure that the added materials can be mixed and reacted quickly and promptly within the reaction apparatus, this embodiment presents the following design:
[0029] The mixing assembly 3 includes a motor 31, a drive rod 32, a support plate 33, and mixing rods 34. The motor 31 is located at the end of the return pipe 23. The output end of the motor 31 is equipped with a drive rod 32. The support plate 33 is located on the outside of the drive rod 32. Multiple sets of mixing rods 34 are located in the middle of the support plate 33. A flow divider 35 is located on the inside of the return pipe 23. The flow divider 35 is arranged in a ring. When the added material enters the return pipe 22 from the addition pipe, the support plate 33 and the mixing rods 34 driven by the motor 31 can work with the multiple flow dividers 35 to quickly divide and disperse the reactants and the added material, so that the reactants and the added material are quickly mixed and then enter the reaction pipe 21 for mixing and flow reaction.
[0030] Working principle and usage process of this utility model:
[0031] When using:
[0032] First, the materials for pesticide production are sequentially fed into the return pipe 22 of the reaction assembly 2 located at the top inside the reaction chamber 1 through the feed pipe 11. Next, the liquid guide pipe 52 in the temperature control assembly 5 introduces external hot and cold media into the temperature control sleeve 51, changing the reaction environment in the reaction tube 21. At this time, the materials flow and react in the return pipe 22. When the flowing materials pass through multiple sets of baffles 42, the baffles 42 can turbulently cut the materials, improving the uniformity of material mixing. After the materials have mixed and reacted, they flow into the next stage of the reaction assembly 2 through the discharge pipe 24 for further reaction. Then, the secondary reaction component 2 is fed into the return pipe 22 through the feeding pipe 12 with the materials required for different steps and mixed with the materials. During this process, the motor 31 in the mixing component 3 drives the drive rod 32 to rotate. The support plate 33 on the outside of the drive rod 32 can drive the mixing rod 34 to rotate. With the help of multiple diversion rods 35, the added materials and the flowing reaction materials are quickly and fully mixed together to ensure that the materials can react stably and fully according to the steps of pesticide production. The products after multiple reactions are discharged from the reaction box 1 and made into pesticides by distillation or recrystallization as needed.
[0033] During the reaction process of pesticide production:
[0034] During operation of the reaction device, monitoring equipment such as pressure sensors and flow sensors can be installed to monitor the pressure and flow changes in the reaction tube 21 in real time. When the reaction effect of materials at different levels is not good, motor 2 45 can drive the crossbar 41 and the baffle 42 to rotate. Then, the electric push rod 43 drives the crossbar 41 and the baffle 42 to move back and forth in the reaction tube 21 to ensure that there is no material deposition or blockage in the reaction tube 21 that affects the flow and mixing reaction of materials. This allows the materials to flow stably in the reaction tube 21, the first return tube 22 and the second return tube 23. The materials can continuously mix and react during the flow, achieving the purpose of stable mixing reaction of materials in the reaction component 2, thereby ensuring that the materials reach the expected mixing reaction state.
