Detailed Implementation

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

[0027] Please see Figure 1-7 This utility model provides a technical solution: a reaction vessel for producing a high-performance water-reducing agent, comprising a vessel body 1, a central component 2 inside the vessel body 1, the central component 2 including a connecting cylinder 21, a central cylinder 22, and connecting rods 23, the connecting cylinder 21 being movably installed at the middle position of the upper wall of the vessel body 1, the central cylinder 22 being sleeved at the end of the connecting cylinder 21, the connecting cylinder 21 and the central cylinder 22 being fixedly connected by the connecting rods 23, the connecting rods 23 being arranged in a circumferential array, the upper and lower ends of the central cylinder 22 being connected to the vessel body. A gap is left between the two parts. The inner wall of the central cylinder 22 is arranged with an inner stirring rod 3 in a circumferential array. The outer wall of the central cylinder 22 is arranged with an outer stirring rod 4 in a circumferential array. The end of the outer stirring rod 4 is fixedly installed with a scraper 5 by a fastening bolt. The scraper 5 slides in contact with the inner side wall of the vessel body 1. A temperature sensor 6 is fixedly installed in the middle position of the inner part of the connecting cylinder 21. A driving component 7 is provided at the upper end of the vessel body 1 to drive the connecting cylinder 21 to rotate. A feeding component 8 is provided at the upper edge of the vessel body 1 and a discharging component 9 is provided at the lower center position.

[0028] The vessel body 1 is the main container of the reactor, used to hold chemical reactants. The central component 2 includes a connecting cylinder 21, a central cylinder 22, and connecting rods 23. They work together to enhance the stirring effect, forming a rotatable structure. This design can effectively convert mechanical energy into fluid kinetic energy, promoting the mixing of reactants. The connecting cylinder 21 is movably installed in the middle of the upper wall of the vessel body 1, allowing rotation. The central cylinder 22 is sleeved on the end of the connecting cylinder 21 and fixed by the connecting rods 23. These connecting rods 23 are arranged in a circumferential array. The inner stirring rod 3 and the outer stirring rod 4 are located on the inner and outer sides of the central cylinder 22, respectively, which can generate complex flow patterns, further enhancing the mixing of reactants. The uniformity of the material helps to mix the reactants and promotes a more uniform reaction. The scraper 5 is fixed to the end of the outer stirring rod 4 and is installed by fastening bolts. It can slide in contact with the inner wall of the vessel 1 to help remove the material adhering to the inner wall of the vessel 1 and avoid the accumulation of material affecting the reaction. The temperature sensor 6 is placed in the middle of the connecting cylinder 21 to monitor the temperature change inside the reactor and ensure that the reaction conditions meet the requirements. The drive component 7 is located at the upper end of the vessel 1 and is responsible for driving the connecting cylinder 21 to rotate, thereby making the entire central component 2 rotate to realize the stirring function. The feed component 8 and the discharge component 9 are located at the upper edge and lower center of the vessel 1, respectively, for adding reactants and discharging products.

[0029] Specifically, the external stirring rod 4 includes a sleeve rod 41, a telescopic rod 42, a spring 43, and a piston plate 44. The sleeve rod 41 is fixedly installed on the outer side wall of the central cylinder 22, and a movable cavity 411 is opened inside the sleeve rod 41. One end of the telescopic rod 42 extends into the movable cavity 411 and is fixedly installed with the piston plate 44. The spring 43 is fixedly installed at one end of the piston plate 44 adjacent to the central cylinder 22, and the other end of the telescopic rod 42 is fixedly connected to the scraper 5.

[0030] The sleeve rod 41 is fixedly installed on the outer wall of the central cylinder 22, and has an internal movable cavity 411. The sleeve rod 41 provides space for the telescopic rod 42 to move and is the basic support part of the entire device. One end of the telescopic rod 42 extends into the movable cavity 411 inside the sleeve rod 41 and is fixedly connected to the piston plate 44, while the other end is fixedly connected to the scraper 5. By moving the telescopic rod 42, the position of the scraper 5 can be adjusted to adapt to different operating conditions. The spring 43 is located between the piston plate 44 and the central cylinder 22, providing an elastic force that allows the telescopic rod 42 to extend and retract freely within a certain range. This allows the scraper 5 to automatically adjust its pressure according to the condition of the inner wall of the vessel, ensuring good contact without damaging the inner wall. The piston plate 44 is fixed to the extension... One end of the telescopic rod 42 is located in the movable cavity 411 of the sleeve rod 41. It works together with the spring 43 to ensure that the telescopic rod 42 can move smoothly in the movable cavity 411 and return to the initial position when no external force is applied. Due to the presence of the spring 43, when the scraper 5 encounters resistance, such as encountering hard deposits or encountering uneven pressure distribution during the rotation of the reactor, the telescopic rod 42 can be compressed or extended accordingly, thereby reducing the risk of equipment damage. The scraper 5 can fit more tightly against the inner wall of the reactor body 1 as needed, which is particularly effective for removing residues attached to the inner wall, thereby reducing cleaning time and cost. If it is necessary to replace or repair the scraper 5 or other parts, this will be easier to perform due to its modular design.

[0031] Specifically, the driving component 7 includes a servo motor 71, a driving gear 72, a driven gear 73, and a protective cover 74. The servo motor 71 is fixedly installed on the upper end of the vessel body 1, and the driving gear 72 is fixedly installed on the output end of the servo motor 71. The driven gear 73 is fixedly installed on the outer wall of the connecting cylinder 21. The driving gear 72 and the driven gear 73 are meshed together. The protective cover 74 is fixedly installed on the upper end of the vessel body 1. The servo motor 71, the driving gear 72, and the driven gear 73 are all located inside the protective cover 74.

[0032] Efficient power transmission can be achieved through the meshing of the driving gear 72 and the driven gear 73. This mechanical connection method is relatively simple but very effective and can withstand high torque loads. The presence of the protective cover 74 increases the safety of the equipment, reduces its sensitivity to external factors, and makes the internal components easier to maintain and clean, thus extending the service life of the equipment.

[0033] Specifically, the feeding component 8 includes a feeding cylinder 81 and a threaded cover 82. The feeding cylinder 81 is fixedly installed through the upper edge of the vessel body 1, and the threaded cover 82 is threadedly connected to the upper end of the feeding cylinder 81. The discharging component 9 includes a discharging cylinder 91 and a control valve 92. The discharging cylinder 91 is fixedly installed at the lower center of the vessel body 1, and the control valve 92 is disposed on the discharging cylinder 91.

[0034] The feed unit 8 adopts a threaded cap 82 design to ensure sealing and avoid the risk of leakage during the reaction process. The presence of the control valve 92 in the discharge unit 9 can effectively control the discharge of materials and prevent accidental overflow. The reasonable feed and discharge design helps to improve the efficiency of the entire production process, reduce material loss, and optimize resource utilization.

[0035] Specifically, the vessel body 1 includes a top plate 11, a hollow cylinder 12, a maintenance plate 13, a bottom plate 14, and support legs 15. The top plate 11 and the hollow cylinder 12 are fixedly connected by fastening bolts, and the hollow cylinder 12 and the bottom plate 14 are fixedly connected by fastening bolts. The support legs 15 are arranged in a circumferential array at the lower end of the bottom plate 14. The side wall of the hollow cylinder 12 has a maintenance port, and the maintenance plate 13 is fixedly installed in the maintenance port by fastening bolts.

[0036] The modular design is achieved by connecting the various components with fastening bolts, which not only facilitates installation and disassembly, but also makes subsequent maintenance and upgrades easier. The design of the inspection plate 13 allows operators to perform internal inspections and maintenance without completely disassembling the reactor, which greatly improves work efficiency and reduces downtime. The sturdy support legs and reasonable structural design can effectively resist the influence of external environment, such as earthquakes or strong winds, while also reducing the risk of equipment damage caused by vibration.

[0037] Specifically, the adjacent outer stirring rods 4 in the circumferential direction are arranged in a staggered manner;

[0038] By staggering adjacent outer stirring rods 4 in the circumferential direction, the symmetry of fluid flow can be broken, increasing turbulence and thus improving the mixing effect between materials. This asymmetrical design helps prevent the formation of fixed flow patterns and avoids mixing dead zones. In the longitudinal direction, the distance between adjacent scrapers 5 is less than the length of the scraper 5. When the distance between adjacent scrapers 5 is less than the length of the scraper 5 itself, it means that there is a certain overlap area between the scrapers 5, ensuring that even if there are slight deviations or incomplete alignment during the movement of the scrapers 5, all parts of the inner wall of the vessel 1 can be covered without leaving any dead zones. In addition, the smaller distance also helps to increase the contact frequency of the scrapers with the vessel wall, further improving the cleaning effect and reducing the accumulation of residues.

[0039] Working Principle: The vessel body 1 is the main container of the reactor, used to hold chemical reactants. The central component 2 includes a connecting cylinder 21, a central cylinder 22, and connecting rods 23. They work together to enhance the stirring effect, forming a rotatable structure. This design can effectively convert mechanical energy into fluid kinetic energy, promoting the mixing of reactants. The connecting cylinder 21 is movably installed in the middle of the upper wall of the vessel body 1, allowing rotation. The central cylinder 22 is sleeved on the end of the connecting cylinder 21 and fixed by the connecting rods 23. These connecting rods 23 are arranged in a circumferential array. The inner stirring rods 3 and the outer stirring rods 4 are located on the inner and outer sides of the central cylinder 22, respectively, which can generate complex flow patterns, further enhancing the mixing effect. The uniformity of the materials helps to mix the reactants and promotes a more uniform reaction. The scraper 5 is fixed to the end of the outer stirring rod 4 and is installed by fastening bolts. It can slide in contact with the inner wall of the vessel body 1 to help remove the material adhering to the inner wall of the vessel body 1 and avoid the accumulation of material affecting the reaction. The temperature sensor 6 is placed in the middle position inside the connecting cylinder 21 to monitor the temperature change inside the reactor and ensure that the reaction conditions meet the requirements. The drive component 7 is located at the upper end of the vessel body 1 and is responsible for driving the connecting cylinder 21 to rotate, thereby causing the entire central component 2 to rotate and realize the stirring function. The feed component 8 and the discharge component 9 are located at the upper edge and lower center of the vessel body 1, respectively, for adding reactants and discharging products.
