Description

Technical Field

[0001] This utility model relates to the technical field of reaction vessel stirring equipment, and in particular to a stirring device for a dichlorvos reaction vessel. Background Technology

[0002] The stirring device for a reaction vessel is a core functional component installed inside the reaction vessel to achieve material mixing, heat transfer, and mass transfer. It is widely used in reaction processes in industries such as chemical, pharmaceutical, and food. Its core function is to drive the stirring element to rotate, breaking the static state of the materials, ensuring uniform contact between different components, enhancing the temperature field distribution within the vessel, accelerating heat transfer, and promoting the diffusion and exchange of reaction products and raw materials, thus ensuring efficient and stable reaction. The device typically consists of a stirring shaft, stirring paddles (such as paddle, turbine, or anchor types), a drive motor, and a reduction gear mechanism. The appropriate structural form must be selected based on the material viscosity and reaction process requirements to ensure both effective stirring and production safety.

[0003] However, the existing stirring devices in the reactors are mostly single-speed stirring components, which cannot adapt to the different stages of the dichloroxychloride reaction. In the early stage of the reaction, the raw materials need to be dispersed quickly, and in the later stage, the crystals need to be scraped off slowly. Therefore, it is necessary to stop the machine to replace the stirring components or adjust the structure. The interruption of the reaction process during the shutdown not only increases the number of operation steps, but also prolongs the overall reaction time, which greatly affects the production efficiency. In addition, the existing equipment mostly relies on the unidirectional power of the rotating stirring blades, which results in insufficient flow of raw materials in the reactor and slow dispersion speed. This can easily lead to situations where the raw material concentration is too high in some areas and too low in others. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stirring device for a dichloroxychloride reaction vessel includes a stable base, a swing base slidably mounted on the inner side of the stable base, a reaction vessel fixedly mounted on the inner side of the swing base, a cover detachably mounted on the top of the reaction vessel via a flange, and a drive housing fixedly mounted on the top of the cover; two guide columns are fixedly mounted on each side of the swing base, and the four guide columns slide through the inner walls of both sides of the stable base.

[0006] Specifically, inertia grooves are provided on both sides of the swing base, and eccentric blocks are rotatably installed on the inner side of the two inertia grooves, so that inertia is generated by the rotation of the two eccentric blocks, thereby driving the swing base to swing.

[0007] Specifically, the swing base has two motor slots inside, and a swing servo motor is fixedly installed on the inner side of each of the two motor slots. The output shafts of the two swing servo motors are respectively fixedly connected to the corresponding eccentric blocks, so as to drive the eccentric blocks to rotate through the swing servo motors.

[0008] Specifically, springs are fitted on the outer sides of the four guide pillars. The two ends of the four springs are fixedly connected to the two sides of the swing base and the inner wall of the stable base, respectively. When the swing base swings, the four springs provide traction force and rebound force respectively, thereby reducing its swing and floating but increasing the swing frequency.

[0009] Specifically, the drive housing has a drive chamber inside, and a double row of drive wheels is rotatably mounted on the bottom inner wall of the drive chamber. The drive housing also has a drive groove inside, and a drive servo motor is fixedly mounted on the inner side of the drive groove. The output shaft of the drive servo motor is fixedly connected to the double row of drive wheels, so as to drive the double row of drive wheels to rotate through the drive servo motor.

[0010] Specifically, a fast wheel is rotatably mounted on the bottom inner wall of the drive chamber, and a slow wheel is rotatably mounted on the top inner wall of the drive chamber. The diameter of the slow wheel is larger than that of the fast wheel, so there is a speed difference between the slow wheel and the fast wheel.

[0011] Specifically, the same slow belt is wound between the double-row drive pulley and the slow pulley, and the same fast belt is wound between the double-row drive pulley and the fast pulley.

[0012] Specifically, a fast shaft is fixedly installed at the bottom of the fast wheel, and the fast shaft extends into the reactor. A slow shaft is fixedly installed at the bottom of the slow wheel, and the slow shaft rotates through the fast shaft.

[0013] Specifically, the outer side of the high-speed shaft is fixedly fitted with a disc-type stirring blade and multiple paddle-type stirring blades, which can realize the rapid dispersion of raw materials and avoid local concentration differences.

[0014] Specifically, an anchor-type stirring blade is fixedly installed at the bottom of the slow-speed shaft. The bottom of the anchor-type stirring blade slides in contact with the inside of the reactor, which can scrape the crystallized material, prevent it from sticking to the wall and coking, and ensure the purity of the product.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The stirring device of the dichloroxychloride reaction vessel of this utility model can make a speed difference between the fast shaft and the slow shaft by setting a fast wheel and a slow wheel. The fast shaft drives the disc and paddle stirring blades to meet the initial raw material dispersion, while the slow shaft drives the anchor stirring blades to complete the later wall scraping. There is no need to stop the machine to replace parts or adjust the structure. The reaction is carried out continuously throughout the process, saving the time spent on shutdown operation, effectively shortening the overall reaction cycle and greatly improving production efficiency.

[0017] (2) The stirring device of the dichloroxychloride reaction vessel of this utility model can quickly disperse the raw materials by setting the high speed of the fast shaft. At the same time, the shearing force and tumbling force generated by the swing base form a compound stirring effect, which accelerates the flow and mixing of materials, makes the materials evenly distributed in the vessel, avoids the generation of local concentration differences, and enhances the practicality of the equipment.

[0024] Reference Figure 1-5 A stirring device for a dichlorvos-sulfuron-methyl reactor includes a stable base 1, a swing base 2 slidably mounted on the inner side of the stable base 1, a reactor 7 fixedly mounted on the inner side of the swing base 2, a cover 8 detachably mounted on the top of the reactor 7 via a flange, and a drive housing 9 fixedly mounted on the top of the cover 8; two guide columns 5 are fixedly mounted on both sides of the swing base 2, and the four guide columns 5 slide through the inner walls of both sides of the stable base 1 respectively.

[0025] In this embodiment, inertia grooves are provided on both sides of the swing base 2, and eccentric blocks 3 are rotatably installed on the inner side of the two inertia grooves, so that inertia is generated by the rotation of the two eccentric blocks 3, thereby driving the swing base 2 to swing.

[0026] In this embodiment, two motor slots are provided inside the swing base 2. A swing servo motor 4 is fixedly installed on the inner side of each of the two motor slots. The output shafts of the two swing servo motors 4 are respectively fixedly connected to the corresponding eccentric blocks 3, so as to drive the eccentric blocks 3 to rotate through the swing servo motors 4.

[0027] In this embodiment, springs 6 are fitted on the outer sides of the four guide posts 5. The two ends of the four springs 6 are fixedly connected to the two sides of the swing base 2 and the inner wall of the stable base 1, respectively. When the swing base 2 swings, the four springs 6 provide traction force and rebound force to it, thereby reducing its swing floating but increasing the swing frequency.

[0028] In this embodiment, a drive chamber is provided inside the drive housing 9, and a double row of drive wheels 10 is rotatably mounted on the bottom inner wall of the drive chamber. A drive groove is provided inside the drive housing 9, and a drive servo motor 11 is fixedly mounted on the inner side of the drive groove. The output shaft of the drive servo motor 11 is fixedly connected to the double row of drive wheels 10, so as to drive the double row of drive wheels 10 to rotate through the drive servo motor 11.

[0029] In this embodiment, a fast wheel 17 is rotatably mounted on the bottom inner wall of the drive chamber, and a slow wheel 13 is rotatably mounted on the top inner wall of the drive chamber. The diameter of the slow wheel 13 is larger than the diameter of the fast wheel 17, so there is a speed difference between the slow wheel 13 and the fast wheel 17.

[0030] In this embodiment, the same slow belt 12 is wound between the double-row drive pulley 10 and the slow pulley 13, and the same fast belt 16 is wound between the double-row drive pulley 10 and the fast pulley 17.

[0031] In this embodiment, a fast shaft 18 is fixedly installed at the bottom of the fast wheel 17, and the fast shaft 18 extends into the reactor 7. A slow shaft 14 is fixedly installed at the bottom of the slow wheel 13, and the slow shaft 14 rotates through the fast shaft 18.

[0032] In this embodiment, a disc-type stirring blade 19 and multiple paddle-type stirring blades 20 are fixedly sleeved on the outer side of the high-speed shaft 18, which can realize the rapid dispersion of raw materials and avoid local concentration differences.

[0033] In this embodiment, an anchor-type stirring blade 15 is fixedly installed at the bottom end of the slow-speed shaft 14. The bottom of the anchor-type stirring blade 15 slides in contact with the inside of the reactor 7, which can scrape the crystallized material, prevent it from sticking to the wall and coking, and ensure the purity of the product.

[0034] Working Principle: During the dichloroxylenol-sulfuron-methyl stirring reaction, the operator adds the material to the reaction vessel 7, then closes the sealing cap 8 and starts the drive servo motor 11. The drive servo motor 11 drives the double-row drive wheels 10 to rotate. The rotation of the double-row drive wheels 10 drives the corresponding slow-speed wheels 13 and fast-speed wheels 17 to rotate via the slow-speed belt 12 and the fast-speed belt 16, respectively. The diameter of the slow-speed wheel 13 is larger than that of the fast-speed wheel 17, so the speed of the slow-speed wheel 13 is lower than that of the fast-speed wheel 17. The slow-speed wheel 13 is fixedly sleeved on the slow-speed shaft 14, and the fast-speed wheel 17 is fixedly sleeved on the fast-speed shaft 18, so the speed of the fast-speed shaft 18 is higher than that of the slow-speed shaft 14. That is, the speed of the disc-type stirring blades 19 and the multiple paddle-type stirring blades 20 is higher than that of the anchor-type stirring blades 15, so that the raw materials can be rapidly dispersed synchronously in the early stage of the reaction, avoiding localized mixing. The concentration difference reduces side reactions, and the material is scraped and crystallized simultaneously in the later stage to prevent sticking and coking, ensuring product purity. No machine shutdown or switching is required, shortening the reaction cycle. While stirring, the operator starts two swing servo motors 4, which drive the corresponding eccentric blocks 3 to rotate. The rotation of the two eccentric blocks 3 generates inertia, which drives the same swing base 2 to move left and right. Two guide columns 5 are fixedly installed on both sides of the swing base 2, and springs 6 are sleeved on the outside of the four guide columns 5. The four springs 6 provide traction force and rebound force to the swing base 2 when it swings, which reduces the swing floating of the swing base 2 but increases the frequency. Through the combined effect of shear force and overturning force generated by the shaking, the stirring efficiency is greatly improved, enhancing the practicality of the equipment and the quality of the finished product.

[0035] The technological advancements of this invention compared to existing technologies are as follows: It eliminates the need for machine shutdown to replace parts or adjust the structure, allowing for continuous reaction throughout the entire process. This saves time spent on shutdown operations, effectively shortens the overall reaction cycle, and significantly improves production efficiency. Furthermore, the high-speed stirring can quickly disperse the raw materials, and combined with the shearing and tumbling forces generated by the oscillating base 2, a compound stirring effect is formed, accelerating the flow and mixing of materials. This ensures uniform distribution of materials within the reactor, avoids localized concentration differences, and enhances the practicality of the equipment.
