[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 2 As shown in the embodiment of this utility model, an auxiliary reaction device for an ethoxylation dual-circulation reactor includes a base plate 1; a reaction chamber 11 is fixedly connected to the top of the base plate 1; a pair of rotating shafts 12 are rotatably connected to the top of the reaction chamber 11; a sealing cover 13 is fixedly connected to the surface of the rotating shaft 12; one of the sealing covers 13 has a protrusion on its side wall; the other sealing cover 13 has a groove on its side wall; the pair of sealing covers 13 are mutually fitted; an air inlet pipe 14 is connected to the side wall of the reaction chamber 11; a first valve 15 is fixedly connected to the middle of the air inlet pipe 14. During operation, the sealing cover 13 is first opened by rotating the rotating shaft 12, then the reactor is placed inside the reaction chamber 11, then the sealing cover 13 is closed to make them interlock, then the end of the air inlet pipe 14 is connected to a heating device, and then the air inlet pipe 14 is opened to allow it to perform an auxiliary reaction in the reactor. By equipping this device, the reaction time of the reactor to the material can be accelerated, thereby improving production efficiency. At the same time, since a sealing cover 13 is provided on the top of the reaction chamber 11, which fits into each other during operation, it helps to improve the sealing of the middle part of the reaction chamber 11.

[0024] like Figure 2 As shown, a first electric actuator 2 is fixedly connected to the bottom of the reaction chamber 11; a tray 21 is fixedly connected to the top of the first electric actuator 2. By providing this device at the bottom of the reaction chamber 11, when the reactor enters the reaction chamber 11, the first electric actuator 2 can be controlled to extend or retract first, then the reactor can be placed on top of the tray 21, and then the tray 21 can be controlled to return to its original position. This setting enables automatic lifting and lowering of the reactor, maintaining stable operation during the lifting and lowering process, and reducing the occurrence of problems such as shaking and vibration that could cause spillage of materials inside the reactor when the reactor enters the reaction chamber 11.

[0025] like Figure 4 As shown, a plurality of second electric actuators 3 are fixedly connected to the middle of the reaction chamber 11; a limiting plate 31 is fixedly connected to the end of the second electric actuator 3. After the reactor is placed inside the reaction chamber 11, the second electric actuators 3 are controlled to extend and retract. At this time, the limiting plate 31 moves toward the reactor. When the surface of the limiting plate 31 contacts the reactor, the second electric actuators 3 stop extending and retracting. By providing this device in the middle of the reaction chamber 11, the reactor can be fixed, reducing the possibility of displacement or tilting of the reactor during the reaction process inside the reaction chamber 11, which could lead to spillage of materials inside the reactor. At the same time, it can improve the stability of the equipment during operation.

[0026] like Figures 3 to 4 As shown, multiple rubber pads 4 are fixed to the surface of the limiting plate 31. When the limiting plate 31 fixes the reactor, the shape of the rubber pads 4 changes as the second electric push rod 3 extends and retracts. At this time, the rubber pads 4 first adhere to the surface of the reactor. By providing this device on the surface of the limiting plate 31, the friction or scratching of the reactor surface caused by the limiting plate 31 when fixing the reactor can be reduced. At the same time, the stability of the limiting plate 31 in fixing the reactor can be improved.

[0027] like Figure 1 As shown, a heat-insulating cotton 5 is fixedly attached to the top of the base plate 1; the end of the heat-insulating cotton 5 is fixedly attached to the reaction chamber 11; the heat-insulating cotton 5 is wrapped around the middle of the reaction chamber 11. By providing heat-insulating cotton 5 on the outer wall of the reaction chamber 11, the heat-insulating cotton 5 can reduce heat loss during operation through its own heat-insulating properties. Through this device, the internal temperature of the reaction chamber 11 can be kept uniform, reducing the impact on the reactor's reaction effect on the materials due to heat loss inside the reaction chamber 11.

[0028] like Figure 5 As shown, a detector 6 is installed on the side wall of the reaction chamber 11; a pressure relief pipe 61 is connected to the side wall of the reaction chamber 11; and a second valve 62 is fixedly connected to the middle of the pressure relief pipe 61. During operation, by providing this device on the side wall of the reaction chamber 11, the internal temperature and pressure of the reaction chamber 11 can be detected in real time. When the internal pressure of the reaction chamber 11 is too high, the second valve 62 is opened to reduce the pressure inside the reaction chamber 11 through the pressure relief pipe 61. Through this device, the pressure change inside the reaction chamber 11 can be monitored in real time, so as to accurately control the internal pressure of the reaction chamber 11 and improve the safety of the equipment during operation.

[0029] The working principle is as follows: First, open the sealing cover 13, then place the reactor inside the reaction chamber 11, and then close the sealing cover 13 to make them fit together. Next, connect the end of the air inlet pipe 14 to the heating device, and then open the air inlet pipe 14 to assist the reactor in the reaction. Because this device is provided at the bottom of the reaction chamber 11, when the reactor enters the reaction chamber 11, the first electric actuator 2 can be controlled to extend or retract, then the reactor can be placed on top of the tray 21, and then the tray 21 can be controlled to return to its original position. After the reactor is placed inside the reaction chamber 11, the second electric actuator 3 can be controlled to extend or retract. At this time, the limiting plate 31 moves towards the reactor. When the limiting plate 31 contacts the reactor, the second electric push rod 3 stops extending and retracting. When the limiting plate 31 fixes the reactor, the shape of the rubber pad 4 changes as the second electric push rod 3 extends and retracts. At this time, the rubber pad 4 first adheres to the surface of the reactor. By providing insulation cotton 5 on the outer wall of the reaction chamber 11, the insulation cotton 5 can reduce heat loss through its own insulation properties during operation. By providing this device on the side wall of the reaction chamber 11, the internal temperature and pressure of the reaction chamber 11 can be detected in real time. When the internal pressure of the reaction chamber 11 is too high, the second valve 62 is opened to reduce the pressure inside the reaction chamber 11 through the pressure relief pipe 61.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
