Description

Technical Field

[0001] The utility model relates to a stirring device, more specifically, to a polystyrene stirring device. Background Art

[0002] Polystyrene refers to a polymer synthesized from styrene monomers through free radical addition polymerization. It is a colorless and transparent thermoplastic. It has a glass transition temperature higher than 100°C, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes. Polystyrene generally uses a reactor as a stirring device to mix the raw materials. Inhomogeneous mixing will result in poor quality of the final product.

[0003] In order to solve the problem that the polystyrene is not mixed evenly in the reactor, resulting in poor quality of the final product, a multi-directional stirring device for polystyrene production in China with publication number CN115674476A has a material barrel rotatably mounted on the lower side of the mounting frame, and a rotating device is mounted on the material barrel. The rotating device drives the material barrel to rotate, and the lateral reciprocating motion of the stirring frame can be achieved through the cooperation of the lever and the grooved sliding rod, so that the polystyrene can be stirred at different angles, which can not only change the stirring position, but also prevent the material barrel from being touched during the lateral reciprocating motion.

[0004] After polystyrene is stirred in the reactor, residues are likely to remain on the inner wall of the reactor, which is time-consuming, labor-intensive and inefficient to handle manually. Therefore, it is necessary to design a polystyrene stirring device with the function of scraping the residues on the inner wall to solve the above problem. Utility Model Content
