Description

Technical Field

[0001] The invention relates to the technical field of chemical production equipment, and more specifically to a reaction kettle for producing polyolefin glue with an anti-caking structure. Background Art

[0002] Reactor is a kind of equipment that can fully mix, react and polymerize the poured raw materials by stirring at the same time. When manufacturing products such as polyolefin glue, reactor is an indispensable equipment in production. The stirring blades in the reactor can fully stir the raw materials placed inside, make them fully mixed and reacted, and improve the production efficiency of the product.

[0003] Based on the above, the inventors found that the agitator of the traditional reactor is mostly composed of a single stirring rod. During the stirring process, the reactants may not be fully mixed, and lumps are easily formed in the reactor, affecting the quality of the product. At the same time, polyolefin glue and other products usually need to be heated during processing, and the traditional reactor is usually heated by immersing the whole in hot water for water bath heating or by heating with a resistance wire and using heat conduction. The water bath heating has a slow heating and cooling speed and low efficiency, while the resistance wire heating has a fast heating speed but difficult temperature control. Therefore, in view of this, the existing structure is studied and improved, and a reactor for polyolefin glue production with an anti-caking structure is provided, in order to achieve a more practical purpose. Summary of the invention
