[0002] After entering winter in northern my country, the temperature is relatively low, and polystyrene particles are sensitive to temperature when foaming. In the prior art, polystyrene particles are usually transported to a foaming tank, and then a foaming agent is added. After high-temperature steam is passed through, the foamed polystyrene particles are stirred and foamed. The foamed polystyrene particles discharged from the foaming tank are dried in a fluidized bed and then transported to a maturation bin for maturation. Generally, the best maturation temperature is 20-28°C. If it is lower than 20°C, it is easy to fail to swell, and if it is higher than 40°C, it is easy to die.
[0003] If the temperature of the aging warehouse is too low, especially in winter, the insulation facilities of ordinary factories are not well done, and the temperature inside the factory is similar to the outdoor temperature. The temperature inside the aging warehouse is very low, and the foaming agent in the foamed polystyrene particles is in liquid state and cannot be vaporized and expanded, resulting in the shrinkage of the foamed polystyrene particles and the poor feel of the finished product. If you want to make a lightweight board, it will be heavier. Therefore, in the cold winter, it is very important to control the foaming conditions of polystyrene particles.
[0004] In addition, in the cold winter, the foamed polystyrene particles after drying in the fluidized bed are also prone to agglomeration, and it is inconvenient to transport them to the maturation bin through the fan. This is the shortcoming of the prior art. Utility Model Content

After being dried in the fluidized bed, the foamed polystyrene particles enter the stirring box. Under the action of the stirring device, the unagglomerated foamed polystyrene particles pass through the filter plate and enter the scraper box below it. The agglomerated foamed polystyrene particles are also broken up and enter the scraper box below it through the filter plate. Under the rotation of the scraper shaft, a large number of foamed polystyrene particles are contained in adjacent scraper plates.
