[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] Refer to Figure 1 、 Figure 3 and Figure 4, an embodiment provided by the present utility model: a large-scale reactor, including a bottom plate 1, the top wall of the bottom plate 1 is fixedly connected with a support frame 3, and a reactor device 4 is placed on the top of the support frame 3. Through the support frame 3, the reactor device 4 can be placed and supported. The top wall of the reactor device 4 is communicated with a connecting shell 5, and both the front and rear sides of the connecting shell 5 are communicated with side shells 6. Through the connecting shell 5, materials can be added into the interior of the reactor device 4. The inner wall of the side shell 6 is fixedly connected with a porous nozzle 7, and the top wall of the porous nozzle 7 is communicated with an access valve 8. Under the connection of the access valve 8, steam can be ejected through the porous nozzle 7. A servo motor 10 is fixedly connected to the right side of the reactor device 4, and the output end of the servo motor 10 is fixedly connected with a stirring rod 11. When the servo motor 10 is started, the stirring rod 11 can stir the materials, thereby improving the reaction rate of the materials. A plurality of discharge valves 13 are equidistantly communicated with the front side of the bottom wall of the reactor device 4, and the bottom end of the discharge valve 13 is communicated with a collection box 15. Through the collection box 15, the condensed water discharged from the discharge valve 13 can be collected. A plurality of temperature measuring probes 14 are equidistantly fixedly connected to the rear side of the bottom wall of the reactor device 4. Under the action of the temperature measuring probes 14, the temperature at the bottom of the reactor device 4 can be detected. A plurality of stabilizing mechanisms 2 are arranged on the inner wall of the support frame 3;

[0040] Specifically, the temperature measuring probe 14 can capture the temperature data at the bottom of the reactor in real time and accurately, so that the discharge time and interval of the discharge valve 13 can be adjusted, and the condensed water is discharged into the collection box 15, avoiding the accumulation of condensed water in the reactor, affecting the temperature distribution of the equipment and the reaction efficiency. After discharging the condensed water, the connecting shell 5 can be opened to add new materials into the reactor device 4. The stirring rod 11 is driven by the servo motor 10 to rotate in the reactor to uniformly mix the materials, not only improving the reaction efficiency, but also ensuring the full contact and reaction between the materials, laying a solid foundation for the subsequent process steps. When the steam enters the reactor device 4 through the access valve 8, it will be sprayed through the porous nozzle 7, quickly and evenly covering every corner of the reactor, thereby accelerating the working rate and effectively avoiding the situation of too high or too low temperature in some sections, solving the problem that the steam heating area is reduced and the temperature is low due to the large accumulation of condensed water in some working sections, thus improving the production efficiency and product quality.

[0041] Refer to Figure 1 , Figure 2 and Figure 5, the stabilizing mechanism 2 includes a plurality of fixing plates 201. The top walls of the plurality of fixing plates 201 are respectively fixedly connected to the inner top wall of the support frame 3. One side of the fixing plate 201 is fixedly connected with a swing cylinder 202. One end of the swing cylinder 202 is fixedly connected with a rotating rod housing 203. By driving the swing cylinder 202, the rotating rod housing 203 rotates. The top end of the rotating rod housing 203 is rotatably connected with a clamping plate 204 through a torsion spring. The top wall of the clamping plate 204 is fixedly connected with a plurality of arc plates 205 at equal intervals, so that the clamping plate 204 rotatably connected through the torsion spring can clamp the reactor device 4. A plurality of arc-shaped grooves 206 are equidistantly opened on the front and rear sides of the reactor device 4. One side of each of the plurality of arc plates 205 is respectively engaged with the corresponding arc-shaped groove 206. Furthermore, under the engagement connection between the arc plates 205 and the arc-shaped grooves 206, the stability of the reactor device 4 during operation is improved;

[0042] Specifically, when the swing cylinder 202 is started, the rotating rod housing 203 swings. The two clamping plates 204 rotatably connected through the torsion spring can rotate towards or away from each other according to the swing of the rotating rod housing 203. Utilizing the elastic potential energy of the torsion spring, the clamping plate 204 can automatically adjust the angle and force when clamping the reactor device, thereby achieving a more fitting clamping effect. The plurality of arc plates 205 thereon also move accordingly and are precisely engaged with the arc-shaped grooves 206 on the reactor device 4, not only enhancing the clamping stability but also further improving the stability of the reactor device during operation, effectively reducing the shaking and vibration of the device, thereby reducing the risk of device damage and improving the safety and efficiency of production.

[0043] Refer to Figure 1 、 Figure 4 and Figure 5 , the stabilizing mechanism 2 further includes a rubber plate 207. One side of the rubber plate 207 is fixedly connected to one side of the clamping plate 204; a control switch 16 is fixedly connected to the left side of the top wall of the support frame 3. The control switch 16 is electrically connected to the servo motor 10, the temperature measuring probe 14, and the swing cylinder 202 respectively; sealing rings 9 are fixedly connected to the top walls of both access valves 8. The outer shape of the sealing ring 9 is designed in a cylindrical shape;

[0044] Specifically, through the rubber plate 207, the clamping and fixing effect of the clamping plate 204 on the reactor device 4 is improved. Through the control switch 16 electrically connected to the servo motor 10, the temperature measuring probe 14, and the swing cylinder 202 respectively, the control switch 16 can complete the opening and closing of the device. Through the sealing ring 9, the sealing performance during the access of the access valve 8 is improved.

[0045] Refer to Figure 1 、 Figure 2 and Figure 3, a plurality of square grooves 12 are formed on the outer wall of the stirring rod 11, and the plurality of square grooves 12 are all designed at equal intervals; both the left and right sides of the inner wall of the bottom plate 1 are fixedly connected with two connecting seats 17, and the top walls of the plurality of connecting seats 17 are all threadedly connected with bolts 18; rubber rings 19 are fixedly connected to the middle parts of the plurality of bolts 18, and the plurality of rubber rings 19 are all designed symmetrically;

[0046] Specifically, the plurality of square grooves 12 improve the shearing force during the stirring of the stirring rod 11, thereby improving the mixing effect on the materials. The connecting seats 17 and the bolts 18 facilitate the fixing and installation of the device. The rubber rings 19 reduce the rotational damage of the bolts 18 to the connecting seats 17.

[0047] Working principle: When starting to use, through the temperature measuring probes 14 at the bottom wall of the plurality of reaction kettle devices 4, the temperature at the bottom of the reaction kettle devices 4 can be detected. Furthermore, the discharge valve 13 can be adjusted for different discharge times and intervals to discharge the condensed water, so that the condensed water is collected by the collection box 15. After discharging the condensed water, the connecting shell 5 is opened and materials are added to the reaction kettle devices 4. When the servo motor 10 drives the stirring rod 11, the materials can be mixed. Then, the steam pipeline is connected to the access valve 8, so that the porous nozzle 7 can output a steam flow, thereby accelerating the working rate, avoiding the situation where the temperature in some sections exceeds the process temperature or the temperature in some sections is lower than the process temperature, eliminating the situation where a large amount of accumulated condensed water in some working sections reduces the heating area of the steam in this section, resulting in a lower temperature in this section of the reaction kettle, and avoiding the possibility that the instability of the key process seriously affects the product quality;

[0048] And by starting the swing cylinder 202, the rotating rod shell 203 swings, so that the two clamping plates 204 rotatably connected to the rotating rod shell 203 through torsion springs can rotate towards or away from each other, so that the clamping plates 204 can clamp the reaction kettle device and can complete adaptive rotation at the same time, achieving the purpose of being more fitted to the reaction kettle device 4. Furthermore, the plurality of arc plates 205 are engaged with the corresponding arc grooves 206, thereby improving the stability of the reaction kettle device 4 during operation, reducing the situation where the reaction kettle device shakes during operation and affects the stability of the device, and improving the working quality of the reaction kettle device 4.
