Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to a material uniform distribution mechanism. Background Art

[0002] Dryer is a highly efficient drying equipment, which can achieve fast and uniform drying by making the material particles fully contact with hot air in a fluidized state. In this state, the heat and mass transfer rates between the material particles and the hot air are significantly improved, which accelerates the evaporation process of water. It is widely used in chemical, food, ceramic, pharmaceutical, polymer and other industries. They are particularly suitable for drying powders, crystals and granular materials with a particle size greater than 50μm.

[0003] SIS plastic elastomers are a special type of material that is often used to make elastomeric parts and structures. "SIS" stands for "Styrene-Isoprene-Styrene", which is the chemical composition of the material. This material is a thermoplastic elastomer that combines the properties of both plastic and elastic. It is suitable for many applications that require a combination of plastic and elastic properties.

[0004] SIS plastic elastomer materials need to be dried during the preparation process. Drying can effectively remove moisture from the material to ensure that it is not affected by moisture during subsequent processing or use. The presence of moisture may affect the performance and structural stability of the material.

[0005] Therefore, when carrying out drying treatment, it is necessary to reasonably control the drying conditions according to the properties and requirements of the specific materials to ensure that the desired effect is achieved and minimize possible negative effects.

[0006] The dryer is divided into a feeding section, a drying section, a cooling section and a discharging section. A swing feeder is installed at the feed end of the dryer. The existing materials are conveyed forward to the wide-width drying machine bed plate of the feeding section by the swing feeder through vibration or a belt conveyor. However, the materials conveyed to the wide-width drying machine bed plate by the swing feeder are unevenly laid, which affects the drying of subsequent materials and the quality of the final dried materials, thereby reducing the quality of the finished products made from the materials.

[0016] Furthermore, the crank-rocker mechanism comprises a connecting rod and a rocker arm, one end of the connecting rod is connected to the rocker arm, the eccentric wheel is connected to the other end of the connecting rod, and the rotating shaft is connected to the other end of the rocker arm.

[0017] Furthermore, the upper end of the discharge hopper is connected to the discharge cyclone separator through a discharge pipe, and a suction pipe is installed at the upper end of the discharge cyclone separator.
