Description
Technical Field
[0001] The utility model belongs to the technical field of granulation equipment, in particular to a product granulation device. Background Art
[0002] Bio-based materials refer to a new type of materials made from renewable biomass or raw materials obtained through biological manufacturing through biological, chemical, physical and other means, such as bioplastics, biomass functional polymer materials, etc. In the preparation process of bio-based materials, it is necessary to mix and stir a variety of raw materials, and then granulate the fully mixed materials, that is, process the above-mentioned bio-based material mixture into granules for later transportation and use.
[0003] For the preparation of bio-based materials, when it comes to mass production, a granulator is needed to granulate the raw material mixture of the bio-based material. Therefore, the performance of the granulator has become an important indicator for judging the efficiency of the bio-based material preparation process and the quality of the finished product. A granulator is a molding machine that can make materials into a specific shape. The existing granulators mainly include two categories, namely, a drum granulator and a ring die granulator. The ring die granulator is a granulation equipment that uses the interaction force between the ring die and the pressure roller in the granulation chamber to extrude the powder material to obtain the required particles. It has the advantages of continuous and stable production process, high production efficiency, strong raw material adaptability, low energy consumption, good molding effect, and high molding rate. During the working process, it was found that the gap between the roller ring die of the ring die granulator has a great influence on the performance of the granulator, including the life of the roller ring die and the quality of particle molding. If the gap is too small, the extrusion pressure between the roller and the ring die will increase, resulting in increased resistance between the two, aggravated wear of the components and increased noise; if the gap is too large, it will lead to difficulty in discharging, too low granulation density and loose particles.
[0004] However, the gap adjustment structure between the pressure roller and the ring die of the traditional ring die granulator is often complicated, and the adjustment process is cumbersome. In addition, during the granulation process, due to the high water content in the material, steam will be generated as the temperature rises. The generated steam fills the granulation chamber. If it is not discharged in time, the material and the steam will be mixed again, resulting in unstable material humidity, cracks in the finished product, and affecting the forming rate of the finished granules. However, the above-mentioned traditional ring die granulator does not have an exhaust function and cannot discharge the steam in the granulation chamber in time, affecting the quality of the finished product.
