Description

Technical Field

[0001] This utility model relates to the field of granulator feeding technology, specifically to a material conveying and mixing device for a granulator. Background Technology

[0002] A granulator is a molding machine that can shape materials into specific shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, ceramics, rubber, and plastics industries. Currently, granulators use various feeding devices to transport raw materials and additives to a mixing device for mixing and stirring. After mixing, the materials are then transported back to the granulator for further processing.

[0003] Chinese Patent No. CN210236285U discloses a material conveying and mixing device for a granulator, including a granulator body, a conveyor frame, a feeding frame, a feeding hopper, a motor, a stabilizing frame, an adjusting column, a feeding hopper, a mixing chamber, a collecting hopper, a stirring rod, a connecting column, and a screw rod. The feeding hopper is mounted on the upper surface of the granulator body, and the feeding frame is connected inside the feeding hopper. The conveyor frame is installed on the left end of the feeding frame, and the mixing chamber is installed on the upper end of the conveyor frame. The motor is installed on the right side of the mixing chamber, and the feeding hopper is installed on the upper end of the mixing chamber. The adjusting column is installed inside the feeding hopper, and the connecting column is installed in the middle of the mixing chamber. A screw rod is fixed on the upper end of the connecting column, and a collecting hopper is installed on the annular side of the screw rod. A stirring rod is installed on the annular side of the connecting column. This design solves the problem of poor performance of existing material conveying and mixing devices for granulators. This utility model has a reasonable structure, is easy to assemble and install, and has a good mixing effect.

[0004] However, the above technical solution has the following shortcomings: the mixing mechanism simply divides the stirring into two simple steps, and only performs a simple preliminary mixing before mixing, which makes the entire stirring path longer. Materials with high density are prone to sinking during the mixing process, resulting in uneven material distribution. In severe cases, even stratification may occur, affecting subsequent granulation operations. Utility Model Content
