Description
Technical Field
[0001] The utility model relates to the technical field of rocking granulators, and specifically to a material receiving mechanism of a rocking granulator. Background Technique
[0002] Rocking granulators are widely used in multiple industries such as medicine, food, and chemical industry. In the pharmaceutical industry, it is used to grind wet mixed powder raw materials into granules, which are dried and then used for pressing tablets. The material receiving mechanism is responsible for collecting and discharging the granule products made by the granulator.
[0003] The material receiving mechanism of a rocking granulator usually includes a discharge port, a collection container, and possibly a guiding device. The granules fall through the discharge port into the lower collection container, and the guiding device may be used to guide the flow direction of the granules to ensure that the granules can accurately fall into the collection container.
[0004] In the traditional material receiving method, the materials are often collected without sufficient screening, resulting in a large amount of impurities and unformed granules in the finished products, which affects the quality of the materials; at the same time, the dust generated during the operation of the granulator, if directly discharged into the production environment, will not only cause air pollution, but may also pose a threat to the health of the operators; therefore, a material receiving mechanism of a rocking granulator is proposed to address the above problems. Content of the Utility Model
