Detailed Implementation

The support base 2 is located on the side of the reactor body 1, and the reactor body 1 and the support base 2 are connected by welding. The polydextrose feed port 3 is located on the upper part of the reactor body 1, and the polydextrose feed port 3 is connected to the reactor body 1 by welding. The polydextrose discharge port 4 is located at the bottom of the reactor body 1, and the polydextrose discharge port 4 is connected to the reactor body 1 by welding. The shaft seat 5 is located on the upper part of the reactor body 1, and the shaft seat 5 is connected to the reactor body 1 by welding. The following components are connected: a sleeve 6 is located on the upper part of the reactor body 1 and is connected to the reactor body 1 by welding. The sleeve 6 has an annular cylindrical structure and an annular flange is provided on the top of the sleeve 6; a hinged sealing cover 9 is located on the upper part of the sleeve 6 and is fixedly connected to the sleeve 6 by bolts. The hinged sealing cover 9 has a circular structure, with a sealing structure on the upper part and an annular flange welded to the bottom of the hinged sealing cover 9; a stirring rotating shaft 10 is located inside the reactor body 1 and is connected to the shaft seat 5; a stirring motor support 11 is located on the upper part of the hinged sealing cover 9 and is connected to the hinged sealing cover 9 by welding; a stirring motor 12 is located on the upper part of the stirring motor support 11 and is connected to the stirring rotating shaft 10 by a coupling 13; Figure 1 and Figure 2 As shown, by setting a bearing 5, a sleeve 6, and an openable sealing cover 9 at the connection between the stirring shaft 10 and the reactor body 1, the connection between the stirring shaft 10 and the reactor body 1 is sealed twice, thereby enhancing the sealing ability of this part and improving the sealing performance of the device.

[0015] Specifically, the connecting pipe 7 is located on the side of the sleeve 6, and the connecting pipe 7 is connected to the sleeve 6 by welding. The connecting pipe 7 has a cylindrical structure, and an annular flange is provided at the end of the connecting pipe 7. The pressure gauge 8 is located on the side of the connecting pipe 7, and the pressure gauge 8 is fixedly connected to the connecting pipe 7 by bolts. Flanges are provided on both sides of the pressure gauge 8, and a sealing flange plate is provided at the right end of the pressure gauge 8. The PLC control component 14 is located on the side of the pressure gauge 8, and the PLC control component 14 is electrically connected to the pressure gauge 8. The audible and visual alarm 15 is located on the side of the PLC control component 14, and the audible and visual alarm 15 is electrically connected to the PLC control component 14.

[0016] Specific implementation steps: When using this device, the material is fed into the interior of the reactor body 1 through the feeding port 3. Then, the stirring motor 12 drives the stirring shaft 10 through the coupling 13 to carry out stirring. During the reaction, if the reaction is too fast and causes rapid expansion, the connection between the stirring shaft 10 and the shaft seat 5 is relatively weak compared to the reactor body 1. When leakage occurs, it will be detected by the pressure gauge 8, and an alarm will be triggered by the PLC control component 14 and the audible and visual alarm 15. The staff can open the polydextrose discharge port 4 in time to release the material to avoid the risk of explosion. The side of the pressure gauge 8 can also be connected to a solenoid valve and pipeline. In case of emergency, if the pressure is too high, the solenoid valve will be automatically opened to release the pressure, which can effectively protect personal and property safety.

[0017] In summary, this polydextrose production reactor, by incorporating a sleeve and a hinged sealing cover at the top of the reactor body, provides a secondary seal for the connection of the stirring shaft, thus ensuring strong sealing performance. Furthermore, the presence of a connecting pipe and pressure gauge on the side of the sleeve allows for rapid detection of leaks at the connection between the stirring shaft and the shaft seat. This triggers the PLC control unit and the audible and visual alarm, prompting operators to take appropriate action. This timely warning system effectively addresses the problems and shortcomings of existing equipment.
