Description

Technical Field

[0001] The utility model relates to the technical field of resin production devices, in particular to a reaction kettle for resin processing. Background Art

[0002] Resin usually refers to an organic polymer that softens or melts after being 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 product processing is called a resin. Resin needs to be modified and produced by a dedicated reactor with different materials. The reactors in the prior art have the following disadvantages: 1. The inner wall of the reactor will slowly stick to a large amount of resin, which is not conducive to full stirring, and the resin is not cleaned on the inner wall, resulting in mixing with the residue during the next physical and chemical reaction, thereby affecting subsequent production and processing. 2. The stirring system is single and difficult to stir evenly. 3. The existing reactor is prone to cause the material to precipitate and adhere to the bottom of the reactor during the processing, which is not conducive to the discharge of the device. 4. Heating is required during the reaction process to make the resin react quickly, and it is also necessary to cool down in time after the reaction. Different reactors will set the heating pipe and cooling pipe on the inner and outer sides of the shell respectively, and their ability to transfer temperature will be reduced, which is not conducive to improving the processing efficiency of the resin.
