Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, and more specifically, to a resin reaction kettle. Background Art

[0002] Resin usually refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic products is called a resin.

[0003] In the production and processing of resin, the resin raw materials need to be heated and mixed in a reactor. Most of the existing reactors have a heating structure installed in the shell, so that the resin raw materials inside the reactor are heated from the outside. This easily leads to uneven heating of the resin raw materials in the reactor, thereby affecting the heating efficiency of the resin raw materials.

[0004] In addition, since the resin raw material is sticky, when the resin raw material is discharged from the reactor, it is easy to adhere to the inner wall of the reactor shell, and the discharge cleanliness is poor;

[0005] In addition, the stirring structure used for stirring the resin raw materials in the existing reactor is relatively simple, and most of them adopt a combination of a stirring shaft and a stirring rod, or a combination of a stirring shaft and a single spiral blade, which causes the resin raw materials to easily flow in one direction when being stirred, affecting the mixing uniformity of the resin raw materials.

[0042] See also Figure 1 and Figure 3 As an implementation of the upper and lower driving structure: the upper and lower driving structure includes two sets of driving columns 20 symmetrically rotatably mounted in the housing 1 through bearings, two sets of scraper rings 10 are threadedly sleeved on the driving columns 20, and the housing 1 is provided with a driving assembly to match the two sets of driving columns 20;

[0043] The driving assembly includes a driving motor 21 . Top ends of the two sets of driving columns 20 extend outward and are provided with a synchronous belt structure 22 . The driving motor 21 is transmission-connected to one of the driving columns 20 .

[0044] Specifically, the drive motor 21 is started, and the corresponding drive column 20 can be controlled to rotate through the drive motor 21. The other drive column 20 can be driven to rotate synchronously through the cooperation of the synchronous belt structure 22. The scraper ring 10 can be controlled to rise and fall inside the shell 1 through the threaded cooperation relationship between the drive column 20 and the scraper ring 10, thereby scraping the surface inside the inner shell 13 and avoiding the residue of resin raw material inside the shell 1.

[0047] See also Figure 1 As an implementation of the shell 1 , a supporting leg 25 is disposed at the bottom end of the shell 1 , and a fixing foot 26 is disposed at the bottom end of the supporting leg 25 .

[0048] Specifically, the overall stable support is achieved through the cooperation of the supporting legs 25 and the fixing feet 26 .

[0049] In summary, when the overall equipment is in use:

[0050] The resin raw material is delivered to the inside of the housing 1 through the feed port, and the heating medium is delivered to the cavity 6 inside the stirring shaft 2 through the heating medium inlet pipe 23, and is distributed to the heating cavity 7 inside the first spiral stirring blade 4 and the second spiral stirring blade 5 through the cavity 6, so as to achieve the heating of the first spiral stirring blade 4 and the second spiral stirring blade 5, and the middle part of the resin raw material inside the housing 1 is stirred and heated by the cooperation of the first spiral stirring blade 4 and the second spiral stirring blade 5;

[0051] At the same time, the heating medium is transported to the interior of the heating coil, and the inner shell 13 is heated by the heating coil, so that the peripheral heating of the resin raw material is achieved when the resin raw material is heated and stirred inside the shell 1, thereby improving the heating effect of the resin raw material in the reactor;

[0052] Synchronously, the first motor 3 is started, and the stirring shaft 2 is driven to rotate by the first motor 3, and the first spiral stirring blade 4 and the second spiral stirring blade 5 are driven to rotate by the stirring shaft 2. Since the first spiral stirring blade 4 and the second spiral stirring blade 5 are arranged in opposite directions, the flow direction of the resin raw material when being stirred in the reactor can be completely disrupted, thereby improving the mixing and stirring efficiency of the resin raw material in the reactor;

[0053] During this process, the first spiral stirring blade 4 and the second spiral stirring blade 5 can stir and heat the resin raw material, thereby improving the reaction effect of the resin raw material in the reactor;

[0054] After the resin raw materials are heated, stirred and mixed in the reactor, the discharge pipe is opened so that the resin raw materials that have completed the reaction can be discharged outward through the discharge pipe;

[0055] After the resin raw material is discharged, the drive motor 21 is started. The drive motor 21 can control the corresponding drive column 20 to rotate. The synchronous belt structure 22 can drive another drive column 20 to rotate synchronously. The threaded matching relationship between the drive column 20 and the scraper ring 10 can control the scraper ring 10 to rise and fall inside the shell 1, thereby scraping the surface inside the inner shell 13 to avoid the resin raw material remaining inside the shell 1.

[0056] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one.
